technical field

Background technique

Explosives, explosive substances, also known as explosives, can produce a rapid chemical reaction when subjected to an appropriate excitation impulse, and emit enough heat and a large amount of gas products, thereby forming a certain mechanical destruction effect and Throwing effect. Explosives are divided into four categories according to their properties and uses: primary explosives, high explosives, gunpowder and pyrotechnic powders. Among them, the main purpose of the priming charge is as a priming agent in the explosion process, which is used to excite the high explosive for detonation. The main purpose of the high explosive is that it has considerable stability as the main charge of various explosives and blasting equipment, and can only cause detonation under the action of a considerable external force, usually under the excitation of the priming charge. The main use of gunpowder is as a propellant, used to launch bullets and shells, and as a fuel for propelling rockets, of which propellant belongs to gunpowder. The main uses of pyrotechnic charges are as charges for flares, smoke bombs, incendiary bombs, and signal flares, as well as tracers to indicate ballistics. The characteristics of propellant and explosive mainly include energy performance, combustion performance, explosive performance, stability and compatibility, etc. Among them, energy performance is an important performance index for designing propellant and explosive formula. For example, for solid propellants, specific impulse It is the energy performance index of solid propellant.

At present, the formulation design of explosives is based on the experience and knowledge of experts in the field combined with chemical experiments, which has disadvantages such as high cost, long cycle, and many repeated experiments. According to conventional practical experience, it takes several years to more than ten years to design, debug, and finalize a practical formula, and it takes a long time to design a practical formula. Therefore, there is currently a lack of a propellant formulation design method based on dual adjustment of dynamic measures and dynamic components, which is simple in method steps, convenient to implement, low in input cost, and short in time, which can effectively solve the problem of existing propellant formulation design methods. The problems of high cost, long period, and repeated experiments are many.

Example 1

In this embodiment, as shown in Figure 1, a formula design method for propellant and explosive based on dual adjustment of dynamic measures and dynamic components, the energy performance of the designed propellant and explosive is between n ₀ and n ₁ , and n ₀ is the designed propellant The lower limit value of the energy performance of the explosive, n ₌ the upper limit value of the energy performance of the designed propellant; the formula design method may further comprise the steps:

Step 1. Basic formula selection: From the pre-established basic formula library, select a basic formula with an energy performance close to that of the designed propellant and explosive as the basic design formula.

In actual use, the designed pyrotechnics are primary explosives, high explosives, gunpowder or pyrotechnic powder.

In this embodiment, the designed explosive is a solid propellant. Moreover, the solid propellant is a modified double-base solid propellant. When carrying out formula design actually, adopt the present invention to also can carry out formula design to primary explosive, high explosive, pyrotechnic powder and other gunpowder.

A plurality of basic formulas of the designed propellants and explosives and the energy properties of each basic formula are stored in the basic formula library. The basic formula includes the names of multiple components used in preparing the designed propellant and explosives and the types, weight percentages, minimum design content and maximum design content of each component. The weight percentages of multiple components in the basic formula The sum of the contents is 100%.

Among them, the minimum design content and the maximum design content are the reference design content to be used in the process of energy performance reduction adjustment in step 3 and energy performance increase adjustment in step 4.

When actually selecting, the energy performance of each basic formula stored in the basic formula library is compared with _n0 and n1 respectively, and _a basic formula or energy index whose energy index is closest to _n0 is found The basic formula closest to n ₁ is used as the basic design formula.

In the actual operation process, it is also possible to first find out a basic formula with an energy index closest to n ₀ (denoted as basic formula 1) and a basic formula with an energy index closest to n ₁ (denoted as basic formula 2), and then calculate The difference between the energy index of the basic formula 1 and n ₀ and the difference between the energy index of the basic formula 2 and n ₁ , and then compare the two differences, and find the basis with the smaller difference Formula (specifically, basic formula 1 or basic formula 2) is used as the basic design formula.

In this embodiment, the design index and requirements of the designed solid propellant are as follows:

The energy performance of the designed solid propellant is: specific impulse=2220.00N·S/kg～2230.00N·S/kg. The low characteristic signature of the designed solid propellant is no or slight smoke. The designed solid propellant is a platform propellant and its burning rate pressure platform range is 6.00Mpa to 9.00Mpa, and the solid propellant charge adopts the screw compression molding manufacturing process.

That is, n ₀ =2220.00N·S/kg, n ₁ =2230.00N·S/kg.

In the present embodiment, the formula components and weight percentages of the selected basic formula are as follows: nitrocellulose (N=12.6%), 52.4%; nitroglycerin, 34.9%; Gena, 8.7%; %; petrolatum, 0.30%; carbon black, 0.20%; RDX, 1.00%; lead phthalate (leadphthalatedibasic, also known as dibasic lead phthalate), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) n _i =2469.8.

In actual use, the role of nitrocellulose (N=12.6%) in the formulation is: binder and energy substance; functional description: energetic binder, which is a single-base, double-base or modified double-base propellant main mechanical skeleton.

The role of nitroglycerin in the formula: plasticizer and energy substance; functional description: nitroglycerin is used to plasticize nitrocellulose (ie, nitrocellulose (N=12.6%)), and the two form a double-base adhesive, bonding Covering the solid components constitutes the mechanical skeleton of the propellant, and the propellant charge is formed by compression or pouring. Nitroglycerin itself is also an oxygen-rich energetic material. In addition to acting as a plasticizer in the propellant, it also has an oxidation effect. It provides the necessary conditions for propellant oxidative combustion even without a dedicated oxidizer in the propellant.

The role of Gena in the formula: Energetic co-solvent; Functional description: Gena is an energetic solvent that assists nitroglycerin to plasticize high-nitrogen nitrocellulose. When using nitrocellulose with a nitrogen content > 13.1%, Gena is usually added to improve the plasticizing effect of nitroglycerin on nitrocellulose.

The role of RDX in the formula: high-energy elemental explosive; functional description: RDX metal nitramine high-energy elemental explosive, adding RDX can greatly increase the energy of the propellant, and it is relatively cheaper than HMX. Its addition does not cause a higher temperature rise to the metal powder.

The role of lead phthalate in the formula: catalyst; function description: form a low-pressure burning rate adjustment effect with graphite (or carbon black) and copper oxide.

No. 2 centralizing agent Diphenyldimethylurea (centralite-2), plays the role of chemical stabilizer in the formula; function description: reduce the decomposition of nitro esters, prolong the storage life of the charge and stabilize it.

The role of Vaseline in the formula: process additive; functional description: Vaseline: propellant charge screw forming process aid or process additive, which acts as a lubricant and reduces the ignition rate caused by friction.

Components with minimum design content = 0 in the basic formula are unnecessary components of the designed propellant and explosive, and components with minimum design content > are essential components of the designed propellant and explosive. In this example, nitrocellulose and nitroglycerin are two essential components of the designed modified double-base solid propellant.

Step 2. Judgment of energy performance: compare the energy performance n _i of the basic design formula selected in step 1 with n ₀ and n ₁ respectively: when n _i >n ₁ , go to step three; when n _i <n When n ₀ ≤n i ≤n 1, enter step four; when n ₀ ≤n _i ≤n ₁ , the formula design process ends, and the basic design formula is a designed formula.

In this embodiment, when the energy performance n _i of the currently selected basic formula is >n ₁ , go to step three.

Step 3: Energy performance reduction adjustment, the process is as follows:

Step 301, determining the level of energy adjustment measures: according to the types of components in the basic design formula and the attribute information of N components in the pre-established component type attribute information database, multiple groups in the basic design formula The level of energy regulation measures for the points is determined.

The attribute information of the N types of components of the designed propellant and explosive is stored in the component type attribute information library, and the attribute information of each component includes the type of the component and the level of energy adjustment measures. The grades of energy regulation measures of N components are arranged according to the contribution of various components to the energy performance of the designed propellants and explosives, and the greater the contribution to the energy performance of the designed propellants and explosives, the higher the level of energy regulation measures . Wherein, N is a positive integer and N≥2.

In the actual formula design, among the various components of the solid propellant, the energy adjustment measures from high to low are high-energy elemental explosives, metal combustion agents, inert co-solvents, plasticizers and adhesives.

In this example, the basic design formula contains nitrocellulose (N=12.6%), nitroglycerin, Gena, No. 2 neutralizer, petrolatum, carbon black, RDX, lead phthalate and copper oxide and other eight components. In this embodiment, the energy adjustment measures of each component in the basic design formula are, from high to low, high-energy elemental explosive (i.e. RDX), co-solvent (i.e. Gena), plasticizer (i.e. nitroglycerin ) and paste (ie nitrocellulose (N=12.6%)).

After the energy performance judgment in step 2, one or more components whose weight percentages in the basic formula described in step 1 cannot be adjusted should be marked as non-adjusted components.

In this embodiment, No. 2 neutralizer, vaseline, carbon black, lead phthalate and copper oxide contribute very little to the energy performance, and No. 2 neutralizer, petrolatum, carbon black, phthalate Components such as lead formate and copper oxide are marked as non-adjusting components. In the process of actually carrying out formula design, the weight percentages of No. 2 intermediate fixative, vaseline, carbon black, lead phthalate and copper oxide etc. remain unchanged.

Step 302, adopting the dual adjustment method of energy adjustment measures and component content adjustments to adjust the formula: combine the pre-established component attribute information database, and follow the order of energy adjustment measures from high to low, from first to last One or more recipe adjustments. The number of component attribute information databases is N. The component attribute information of N components is respectively stored in the N component attribute information databases; the component attribute information of each component includes the attribute information of multiple components belonging to the same category, and each component The attribute information includes the name of the component, the energy contribution level, the minimum design content and the maximum design content, and the energy contribution level of multiple components is determined according to the contribution of each component to the energy performance of the designed propellant and explosive from high to low. Arrangement, and the greater the contribution to the energy performance of the designed propellant and explosive, the higher the energy contribution level. In this embodiment, the minimum design content and the maximum design content of each component in the component attribute information database are in the process of energy performance reduction adjustment in step 3 and energy performance increase adjustment in step 4. The reference design content. When formula adjustment is actually performed, the formula adjustment method for each energy adjustment measure level is the same, and the process is as follows:

Step 3021, energy adjustment measure adjustment: first reduce the weight percentage of the components corresponding to the currently adjusted energy adjustment measure level in the basic design formula to the minimum design content, and then adjust the weight percentage of the remaining components Increase in the same proportion to obtain the adjusted formula; the sum of the weight percentages of all components in the adjusted formula is 100%; in this step, the component corresponding to the currently adjusted energy adjustment measure level is recorded as the currently adjusted components.

Step 3022, energy performance judgment: compare the energy performance n _j of the adjusted formula in step 3021 with n ₀ and n ₁ respectively: when n ₀ ≤ n _{j ≤} n ₁ , the formula design process ends, and in step 3021 The adjusted formula is a designed formula; when n _j <n ₀ , enter step 3023, and adjust the component content through the currently adjusted component; when n _j >n ₁ , enter step 3024, and proceed to the next energy Recipe adjustments at the level of regulatory measures;

Step 3023, component content adjustment: according to the minimum design content and maximum design content of the currently adjusted component, first increase or decrease the weight percentage of the currently adjusted component, and then adjust the weight percentage of the remaining components All are reduced or increased in the same proportion until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends; in this step, the weight percentages of all components in the adjusted formula The sum is 100%, and the adjusted formula is the designed formula;

Step 3024, formula adjustment for the next energy regulation measure level: follow the method described in step 3021 to step 3023, carry out the formula adjustment process for the next energy regulation measure level;

Step 3025, repeating step 3024 one or more times until an adjusted formula with energy properties between n ₀ -n ₁ is obtained, and the formula design process ends.

In this embodiment, when the energy performance is judged in step 2, the energy performance _ni of the basic design formula selected in step 1 is the specific impulse of the selected basic design formula; when the energy performance is judged in step 3022, the adjustment in step 3021 The energy performance n _j of the formulated formula is the specific impulse of the adjusted formula.

In this embodiment, before selecting the basic formula in step 1, it is necessary to use the data processor to establish an energy performance estimation model for energy performance judgment, and the energy performance estimation model is based on the designed propellant and explosive The formula calculates the calculation model of the energy performance of the propellant and explosive; when the energy performance is judged in step 2, step 3022 and step III, the data processor first calls the energy performance estimation model to estimate the energy performance .

In this embodiment, the energy performance estimation model is a theoretical specific impulse calculation model, and the established theoretical specific impulse calculation model is In the formula: _Isp is the theoretical specific impulse (N s/Kg), _Tc is the combustion chamber temperature ( _K ), _Pe is the pressure at the outlet of the engine nozzle (Pa), Pc is the pressure in the combustion chamber (Pa), is the average relative molecular mass of gas phase combustion products, R is the universal gas constant (Kg m/mol K), k is the adiabatic index and the ratio of its specific heat at constant pressure to specific heat at constant volume, where T _c and Both are thermodynamic parameters calculated according to the principle of minimum free energy combined with the mass ratio conversion of solid propellant, and P _e and P _c are engine design parameters input in advance through the parameter input unit. Among them, R=8.3144Kg·m/mol·K, k=1.1～1.3.

In this embodiment, when the dual adjustment method combining energy adjustment measures and component content adjustments is used in step 302 to adjust the formula, it is not necessary to adjust the formula for the energy adjustment measures marked as non-adjusted components; in step 3021, all After the weight percent content of the components corresponding to the currently adjusted level of energy adjustment measures in the above-mentioned basic design formula is reduced to the minimum design content, the weight percentage content of all components marked as non-adjusted components remains unchanged, and the remaining components All components except the adjusted components are increased in the same proportion to obtain the adjusted formula; the sum of the weight percentages of all components in the adjusted formula is 100%.

In this embodiment, in step 3025, step 3024 is repeated one or more times, and after the formula adjustment of the lowest level of energy adjustment measures in the basic design formula is completed, the energy performance n _j of the adjusted formula in the current state is still less than n When ₀ , enter step 3026 to adjust the components; and record the component corresponding to the lowest level of the energy adjustment measure in the adjusted formula in the current state as the currently adjusted component.

Step 3026, component adjustment, the process is as follows:

Step i, component replacement: according to the type of the currently adjusted component and the component attribute information of the component, determine the energy contribution level of the currently adjusted component, and use the component attribute information of the component The stored component with a lower level of energy contribution replaces the currently adjusted component, and the replaced component is recorded as the currently adjusted component.

Step ii. Adjustment of energy regulation measures: first increase the weight percentage of the currently adjusted components to the highest design content, and then reduce the weight percentages of the remaining components in the same proportion to obtain the adjusted formula; after adjustment The sum of the weight percentages of all components in the formula is 100%.

In this step, the currently adjusted component is the component replaced in step i.

Step Ⅲ, energy performance judgment: compare the energy performance n _tmax of the adjusted formula in step ii with n ₀ and n ₁ respectively: when n ₀ ≤ n _tmax ≤ n ₁ , the formula design process ends, and in step ii The adjusted formula is the designed formula; when n _tmax >n ₁ , go to step ⅳ, adjust the component content through the currently adjusted component; when n _t <n ₀ , return to step i, and adjust the component .

Step ⅳ, component content adjustment: according to the method described in step 3023, adjust the component content through the currently adjusted components until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends .

In this embodiment, when adjusting the component content in step 3023, the n _j in step 3022 and the n _i in step 2 are compared with the energy design index of n ₀ ~ n ₁ respectively: when the comparison results in n When _j is closer to the energy design index of n ₀ ~ n ₁ , the formulation adjustment is carried out by gradually increasing the weight percentage of the currently adjusted component starting from the lowest design content, until the energy performance is obtained between n ₀ ~ n ₁ , the formula design process ends; when the comparison shows that n _i is closer to the energy design index of n ₀ ~ n ₁ , use the weight percent of the currently adjusted components from the basic design formula The formulation adjustment is carried out by gradually reducing the weight percentage of the currently adjusted component, until the adjusted formulation with energy performance between n ₀ and n ₁ is obtained, and the formulation design process ends.

In step 3023, after increasing or decreasing the weight percentage of the currently adjusted component each time, the weight percentage of the remaining components is first reduced or increased in the same proportion, and all the components are obtained. The sum of the weight percentages of points is 100% of the adjusted formula, and then the energy performance of the adjusted formula is compared with n ₀ and n ₁ respectively.

When adjusting the component content according to the method described in step 3023 in step ⅳ, first reduce the weight percentage of the currently adjusted component described in step ii to the minimum design content, and then reduce the weight percentage of the remaining components The contents are all increased in the same proportion to obtain an adjusted formula whose weight percentage sum of all components is 100%, and then the energy performance n _tmin of the adjusted formula and n _tmax in step Ⅲ are respectively related to n ₀ ～n ₁ energy design index: when n _tmax is closer to the energy design index n ₀ ~ n ₁ , use the method of gradually reducing the weight percentage of the currently adjusted component starting from the highest design content Adjust the formula until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends; when n _tmin is closer to the energy design index of n ₀ to n ₁ , the Starting from the lowest design content, the formula is adjusted by gradually increasing the weight percentage of the currently adjusted component until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends.

In step ⅳ, after each increase or decrease of the weight percentage of the currently adjusted components, the weight percentages of the remaining components are first reduced or increased in the same proportion to obtain all the components The sum of the weight percentages of points is 100% of the adjusted formula, and then the energy performance of the adjusted formula is compared with n ₀ and n ₁ respectively.

In this embodiment, in order to reduce the energy performance (i.e. specific impulse) of the modified double-base solid propellant, the highest energy adjustment measure level is first used to adjust the energy adjustment measure, wherein the components corresponding to the highest energy adjustment measure level are RDX. Since RDX is an unnecessary component of the designed modified double-base solid propellant and its minimum design content is 0.00%, the content of RDX is reduced to 0.00% first. The weight percentage of nitroglycerin and nitrocellulose is determined according to the ratio of 4:6, and the weight percentage of Gena and nitroglycerin is determined according to the ratio of 1:4. The adjusted formula is as follows: nitrocellulose (N=12.6%), 52.91%; nitroglycerin, 35.27%; Gena, 8.82%; No. 2 medium fixative, 1.0%; vaseline, 0.30%; carbon black, 0.20%; RDXOGEN, 0.00%; LEADPHTHALATEDIBASIC, 1.00%; COPPER OXIDE, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2468.3. Therefore, when the energy performance of the adjusted formula n _j >n ₁ , it is necessary to adjust the formula for the next level of energy adjustment measures.

In order to further reduce the energy performance (i.e. specific impulse) of the modified double-base solid propellant, the next level of energy adjustment measures is used to adjust the energy adjustment measures, wherein the component corresponding to the next level of energy adjustment measures is a co-solvent (i.e. Gena). Since Gena is an unnecessary component of the designed modified double-base solid propellant and its minimum design content is 0.00%, so the content of Gena is reduced to 0.00% first. The weight percentage of nitroglycerin and nitrocellulose is determined according to the ratio of 4:6, and the weight percentage of Gena and nitroglycerin is determined according to the ratio of 1:4. The adjusted formula is as follows: nitrocellulose (N=12.6%), 58.20%; nitroglycerin, 38.80%; Gena, 0.00%; No. 2 medium fixative, 1.0%; vaseline, 0.30%; Lead phthalate (leadphthalatedibasic), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2462.2. Therefore, when the energy performance of the adjusted formula n _j >n ₁ , it is necessary to adjust the formula for the next level of energy adjustment measures. In summary, it can be seen from the energy estimation that even if the content of Gena is adjusted to the minimum allowable amount, the energy performance of the designed double-base modified propellant is still higher than the upper limit of the index, and energy adjustment measures with lower energy levels must be adopted to correspond to Components are further adjusted.

In order to further reduce the energy performance (i.e. specific impulse) of the modified double-base solid propellant, the next level of energy adjustment measures is used to adjust the energy adjustment measures, wherein the component corresponding to the next energy adjustment level is plasticizer ( nitroglycerin). Since nitroglycerin is an essential component of the designed modified double-base solid propellant and its minimum design content is 10.00%, the content of nitroglycerin is reduced to 10.00% first. The weight percentage of nitroglycerin and nitrocellulose is determined according to the ratio of 4:6, and the weight percentage of Gena and nitroglycerin is determined according to the ratio of 1:4. The adjusted formula is as follows: nitrocellulose (N=12.6%), 87.00%; nitroglycerin, 10.00%; No. leadphthalatedibasic), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2288.8. Therefore, when the energy performance of the adjusted formula is >n ₁ , it is necessary to adjust the formula for the next level of energy adjustment measures. In summary, it can be seen from the energy estimation that even if the content of nitroglycerin is adjusted to the lowest design content, the energy performance of the designed double-base modified propellant is still higher than the upper limit of the index, and the corresponding energy adjustment measures with lower energy levels must be adopted. Components are further adjusted.

In order to further reduce the energy performance (i.e., specific impulse) of the modified double-base solid propellant, the next level of energy adjustment measures is used to adjust the energy adjustment measures, where the component corresponding to the next level of energy adjustment measures is the adhesive (i.e. nitrocellulose). In this example, after adjusting the content of nitrocellulose (N=12.0%) to the minimum design content, the energy performance of the adjusted formula is still higher than the upper limit of the index. Therefore, component adjustment is required.

In this example, by reducing the nitrogen content in the nitrocellulose in the current formula, it is expected to reduce the specific impulse performance of the designed formula. That is, nitrocellulose (N=12.6%) was replaced with nitrocellulose (N=12.0%). In order to know as soon as possible whether the current reduction of nitrogen content in nitrocellulose can meet the requirements of increasing the energy to the design index, first adjust the content of nitrocellulose (N=12.0%) to the maximum allowable amount (i.e. the highest design content): 90.00%, and at the same time The weight percentage of nitroglycerin is adjusted to 7.00%. The adjusted formula is as follows: nitrocellulose (N=12.0%), 90.00%; nitroglycerin, 7.00%; No. 2 neutralizer, 1.0%; petrolatum, 0.30%; leadphthalatedibasic), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2208.9. Thus, the energy performance of the adjusted formula is <n ₀ .

Due to the low energy of the current formula, the current strategy for increasing the energy is to adjust the content of nitrocellulose (N=12.0%) to the lowest design content: 85.00%. The adjusted formula is as follows: nitrocellulose (N=12.0%), 85.00%; nitroglycerin, 12.00%; No. leadphthalatedibasic), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2245.5. Thus, the energy performance of the adjusted formulation is >n ₁ . In summary, it can be seen from the energy estimation that after adjusting the content of nitrocellulose (N=12.0%) to 85.00%, the energy performance of the designed double-base modified propellant is higher than the upper limit of the index.

Due to the high energy content of the current formula, the current energy reduction strategy is to adjust the content of nitrocellulose (N=12.0%) to 87.00%. The adjusted formula is as follows: nitrocellulose (N=12.0%), 87.00%; nitroglycerin, 10.00%; No. leadphthalatedibasic), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2231.0. Thus, the energy performance of the adjusted formulation is >n ₁ . In conclusion, it can be seen from the energy estimation that after adjusting the content of nitrocellulose (N=12.0%) to 87.00%, the energy performance of the designed double base modified propellant is still higher than the upper limit of the index.

Due to the high energy content of the current formula, the current energy reduction strategy is to adjust the content of nitrocellulose (N=12.0%) to 89.00%. The adjusted formula is as follows: nitrocellulose (N=12.0%), 89.00%; nitroglycerin, 8.00%; No. leadphthalatedibasic), 1.00%; copper oxide, 0.50%. Moreover, the energy performance of the currently selected basic formula (that is, the specific impulse, specifically the specific impulse value under the state of adiabatic expansion) = 2216.3. Therefore, the energy performance of the adjusted formula is between n ₀ and n ₁ , and the formula design process ends at this time.

In this embodiment, the designed formula is: nitrocellulose (N=12.0%), 89.00%; nitroglycerin, 8.00%; No. Lead phthalate (leadphthalatedibasic), 1.00%; copper oxide, 0.50%.

In this embodiment, after the formula design process in step 3 is completed, the obtained adjusted formula with energy performance between n ₀ and n ₁ needs to be added to the basic formula library.

In this embodiment, when the basic formula is selected in step 1, a data processor is used for selection, and an energy index is selected from the basic formula library through difference comparison, which is closest to the energy design index of n ₀ ~ n ₁ The basic formula of is used as the basic design formula. The basic formula library, the component type attribute information library and multiple component attribute information libraries are all established by the data processor and stored in the data storage, and the data storage and the data processing device connected. The processes of judging energy performance in step 2 and reducing and adjusting energy performance in step 3 are both processed by the data processor. Therefore, the present invention has a very high degree of intelligence and is easy to use and operate, and only needs to adjust the design index, and the formula design process meeting the design index can be completed within ten seconds to a few minutes.

The low characteristic signature of the designed solid propellant is no or slight smoke. The designed solid propellant is a platform propellant and its burning rate pressure platform range: 6.00Mpa～9.00Mpa, and the solid propellant charge adopts the screw compression molding manufacturing process; that is to say, n ₀ =2580.00N·S/kg , n ₁ =2590.00N·S/kg; when judging the energy performance in step 2, if the energy performance of the currently selected basic formula is n _i <n ₀ , then enter step 4.

Step 4021, adjustment of energy adjustment measures: first increase the weight percentage of the component corresponding to the highest level of energy adjustment measure in the basic design formula to the highest design content, and then adjust the weight percentage of the remaining components Reduce the same proportion to obtain the adjusted formula; the sum of the weight percentages of all components in the adjusted formula is 100%; in this step, the component corresponding to the currently adjusted energy adjustment measure level is recorded as the currently adjusted group point.

Step 4022, energy performance judgment: compare the energy performance n _k of the adjusted formula in step 4021 with n ₀ and n ₁ respectively: when n ₀ ≤ n _{k ≤} n ₁ , the formula design process ends, and in step 4021 The adjusted formula is the designed formula; when n _k >n ₁ , go to step 4023 to adjust the component content through the currently adjusted component; when n _k <n ₀ , go to step 4024 to adjust the component .

Step 4023, component content adjustment: according to the method described in step 3023, adjust the component content through the currently adjusted components described in step 4021 until the adjusted energy performance between n ₀ and n ₁ is obtained Recipe, the recipe design process ends.

Step 4024, component adjustment, the process is as follows:

Step Ⅰ, component replacement: according to the type of the currently adjusted component and the component attribute information of the component, determine the energy contribution level of the currently adjusted component, and use the component attribute information of the component The stored component with a higher level of energy contribution replaces the currently adjusted component, and the replaced component is recorded as the currently adjusted component.

Step II, adjustment of energy regulation measures: first increase the weight percentage of the currently adjusted components to the highest design content, and then reduce the weight percentages of the remaining components in the same proportion to obtain the adjusted formula; after adjustment The sum of the weight percentages of all components in the formula is 100%.

In this step, the currently adjusted component is the component replaced in step I.

Step Ⅲ, energy performance judgment: compare the energy performance n _smax of the adjusted formula in step Ⅱ with the difference between n ₀ and n ₁ respectively: when n ₀ ≤ n _smax ≤ n ₁ , the formula design process ends, and in step Ⅱ The adjusted formula is the designed formula; when n _smax >n ₁ , enter step IV, and adjust the component content through the currently adjusted component; when n _smax <n ₀ , return to step Ⅰ, and adjust the component .

Step IV, component content adjustment: according to the method described in step 3023, adjust the component content through the currently adjusted components until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends .

In this embodiment, in step 4021, after raising the weight percentage of the component corresponding to the highest level of energy adjustment measures in the basic design formula to the highest design content in step 4021, the weight of all components marked as non-adjusted components The percentage content remains unchanged, and all components except the adjusted components in the remaining components are increased in the same proportion to obtain the adjusted formula; the sum of the weight percentages of all components in the adjusted formula is 100%.

After the weight percentage of the currently adjusted component is raised to the highest design content in step II, the weight percentage of all components marked as non-adjusted components remains unchanged, and the remaining components except the adjusted components All other components are reduced in the same proportion to obtain an adjusted formula; the sum of the weight percentages of all components in the adjusted formula is 100%.

In this embodiment, the process of performing energy performance increase adjustment in step 4 is processed by the data processor. Moreover, when judging the energy performance in step 4022, the data processor first invokes the energy performance estimation model to perform energy performance estimation.

In this embodiment, when the energy performance is judged in step 4022, the energy performance _nk of the adjusted formula in step 4021 is the specific impulse of the adjusted formula; when the energy performance is judged in step III, the energy performance of the adjusted formula in step II is Performance n _smax is the specific impulse of the adjusted formula.

In this embodiment, when adjusting the component content in step 4023 according to the method described in step 3023, the n _k in step 4022 and the ni in step 2 are firstly compared with the energy design index of n ₀ ~ _{n 1} respectively For comparison: when the comparison shows that n _k is closer to the energy design index of n ₀ ~ n ₁ , the formula adjustment is carried out by gradually reducing the weight percentage of the currently adjusted components starting from the highest design content, until Obtain the adjusted formula with energy performance between n ₀ ~ n ₁ , and the formula design process ends; when the comparison shows that n _i is closer to the energy design index of n ₀ ~ n ₁ , use the formula from the basic design formula Adjust the formula by gradually increasing the weight percentage of the currently adjusted component until the adjusted formula with energy performance between n ₀ and n ₁ is obtained. The formula design process Finish.

When adjusting the component content according to the method described in step 3023 in step IV, first reduce the weight percentage of the currently adjusted component described in step II to the minimum design content, and then reduce the weight percentage of the remaining components to The contents are all increased in the same proportion, and the adjusted formula with the weight percentage of all components being 100% is obtained, and then the energy performance n _smin of the adjusted formula and n _smax in step III are respectively compared with n ₀ ~n ₁ energy design index: when the comparison shows that n _smax is closer to the energy design index n ₀ ~ n ₁ , start from the highest design content to gradually reduce the weight percentage of the currently adjusted component Adjust the formula until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends; when n _smin is closer to the energy design index of n ₀ to n ₁ , adopt Starting from the lowest design content, the formula is adjusted by gradually increasing the weight percentage of the currently adjusted component until the adjusted formula with energy performance between n ₀ and n ₁ is obtained, and the formula design process ends.

Each time in step 4023 and step IV, after increasing or decreasing the weight percentage of the currently adjusted component, first reduce or increase the weight percentage of the remaining components in the same proportion, Obtain the adjusted formula in which the sum of the weight percentages of all components is 100%, and then compare the energy performance of the adjusted formula with n ₀ and n ₁ respectively.

Thus, the energy performance of the adjusted formula is <n ₀ . In summary, it can be seen from the energy estimation that after adjusting the content of RDX to 50.00%, the energy performance of the designed double base modified propellant is still lower than the lower limit of the index.
