Description
Art
The present invention relates to a kind of stratospheric airship.
Background technology
Stratospheric airship had both been different from the aircraft of flight at aviation layer, be different from the traditional dirigible of flight in low latitude, also the satellite of flight on low track is different from, it even can hover over the specific region of advection layer needs at stratospheric height flying for long time, it is a kind of desirable aerospace applicator platform integrating high altitude surveillance, monitoring and communicate, due to the special purpose particularly military use of stratospheric airship, its economic value, military value and social value are deeply military by various countries, the attention of enterprise and scientific circles.Now, although " product " of various media relevant stratospheric airship report, picture and paper cover the sky and the earth, up to the present, also do not see one really can be practical stratospheric airship fly upper advection layer by power.The at present general traditionally principle of dirigible and structure design stratospheric airship per capita, this dirigible must be failed.
1, be difficult to fly into 20Km advection layer by traditional dirigible structure design " stratospheric airship ".
Tradition dirigible has huge balloonet, air is full of in interior, dirigible is when flying into 20Km advection layer, atmospheric density only has about 7% of ground, in dirigible, helium volume is by expansion about 14 times, and the air in the balloonet that traditional dirigible is huge is difficult to discharge in lift-off process, and does not discharge these air, the weight of these air just will become the load of dirigible, and this huge load makes dirigible be difficult to fly into 20Km advection layer.
2, suppose that traditional dirigible can fly to 20Km high-altitude advection layer, because utricule is huge, the inside helium is few again, and helium permeability rate is very high, the leakage of helium quickly, make large dirigible on high the residence time very short, frequently to descend to supplement helium to ground, not only make to safeguard and operating cost very high, and the life-span of its capsule will be very of short duration.
An above difficult problem for stratospheric airship, makes real practical actual stratospheric airship still arrhea on hope and pursue.
Summary of the invention
The object of the invention is to the actual stratospheric airship inventing a kind of real practicality, it can fly the advection layer height of 20Km by means of the power of self and pressure controling mode, and state designed when its utricule itself keeps designing; When returning, it can rely on the power of self to return to ground from the advection layer height of 20Km, and its utricule itself keeps virgin state when taking off from ground; It can have than tradition " stratospheric airship " long number delay sky time doubly.
The technical solution adopted for the present invention to solve the technical problems is: a kind of airbag telescopic type stratospheric airship, be made up of air bag (2), the external air bag of Foldable telescopic (1), empennage (4), gondola (7) etc. in Foldable telescopic body, it is characterized in that: in Foldable telescopic body, air bag (2) entirety is placed among the external air bag of Foldable telescopic (1); Buoyance lift gas is filled with in air bag (2) in Foldable telescopic body, be generally helium or hydrogen, air is full of between air bag (2) and the external air bag of Foldable telescopic (1), to keep the profile of the outer air bag (1) of Foldable telescopic in Foldable telescopic body.
Due to the stretching structure of interior air bag and outer air bag, when dirigible is from ground to stratosphere flight, flight bar pressure limit, limit reduces, expand in inside and outside air bag limit, airship envelope can not be destroyed, add control pressurer system, can ensure that dirigible flies into advection layer safely, need not resemble traditional dirigible and release air a large amount of in balloonet; When returning to ground, action is contrary.As shown in Figure 1.
As can be seen from Figure 1; there is not that main gasbag and the balloonet of traditional dirigible in this dirigible; only have interior air bag and outer air bag; interior air bag is overall as among outer air bag; between them, space is very little, and the air namely deposited is little, the use just in order to protect interior air bag and equilibrium of pressure; there is not dirigible to fly to advection layer from ground and put and do not win air, and fill the problem of not winning air when advection layer flies back ground.
On the other hand, interior air bag entirety is placed among outer air bag, air is full of between interior air bag and outer air bag, owing to being soft pneumatophore, interior air bag is just the same with the pressure within outer air bag, helium in interior air bag outward leakage rate will reduce greatly, just leak in the space between interior air bag and outer air bag when simultaneously, in air bag, helium leakage is gone out, do not drain to outside the outer air bag of dirigible at once, therefore the buoyancy of dirigible is still belonged to, these " leakages " go out the helium of interior air bag, also to carry out second time to leak, spill outer air bag, just calculate and really leaked out dirigible, and this " for the second time " leaks, because in, between outer air bag, the ratio of helium and air is very little, leakage will be very slow.Therefore, the leakage of this dirigible helium is the part of traditional dirigible (prevailing condition limit, and measure not necessarily accurate, the conclusion drawn is about 1/7), and namely this dirigible hang time on high can reach about 7 times of traditional dirigible.
The invention has the beneficial effects as follows:
1, there is not dirigible to fly to advection layer from ground and put and do not win air, and when advection layer flies back ground, fill the problem of not winning air, dirigible can be made to keep profile, fly into advection layer smoothly and return to ground from advection layer.
2, interior air bag is overall as among outer air bag, can improve the dirigible hang time significantly.
Wish that first real practical stratospheric airship flies into advection layer in China, serve Defence business and the society of China.

Detailed description of the invention
Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5 are that in one of the present invention, air bag adopts air bag in Foldable telescopic body, and outer air bag adopts the example structure schematic diagram of the external air bag of Foldable telescopic.This figure dirigible is different from traditional dirigible, completely as can be seen from Fig. 1, Fig. 2 and Fig. 3:
1, in shape, it is different from the prolate spheroid profile of traditional dirigible, the outer air bag top (19A) of its external air bag of Foldable telescopic (1), the interior air bag top (26A) of air bag (2) in (19B) and Foldable telescopic body bottom outer air bag, bottom interior air bag, (26B) is (an X in the horizontal direction respectively, Y-direction) be circular, the peculiar ellipsoid profile utricule that vertical direction (Z-direction) is flat, with on (22) in the middle part of (13) in the middle part of outer air bag and interior air bag, descend and be tightly connected integrally, outer air bag.
The object of this profile design is the relative usage in order to reduce envelop materials, obtains as far as possible large utricule space with as far as possible few envelop materials.The shape of horizontal direction (X, Y-direction) also can be designed to any other shape, select to determine according to every platform dirigible needs separately.
2, structurally, this dirigible is the large ellipsoid of a constancy of volume unlike traditional dirigible, which incorporates a special structural element---in the middle part of the external air bag of Foldable telescopic in (13) and Foldable telescopic body in the middle part of air bag (22).
Tradition dirigible has a huge front balloonet and a huge rear balloonet, what main gasbag also will design simultaneously is very large, because when arriving 20Km high-altitude, in utricule, the volume of helium will increase to about 14 times that helium volume is filled on ground, main gasbag is wanted to adapt to this and is changed, and helium can not run out simultaneously.Main gasbag and front and back balloonet overlapped very large, when dirigible needs to fly upper advection layer, main gasbag is filled with and accounts for the little helium of its volume, and front and back balloonet is full of air; When flying to advection layer, main gasbag full volumetric expands, and balloonet full volumetric bleeds off air.Problem is, in huge balloonet, the air of huge volume does not so easily run out, and valve is also not easy to match with dirigible climbing speed, so conventional confguration dirigible is difficult to fly into advection layer when exitting.When traditional dirigible returns to ground from advection layer, along with dirigible height constantly reduces, dirigible ambient atmosphere pressure constantly increases, dirigible helium volume is forced constantly to shrink, front and back balloonet must be filled with same volume air with identical speed enters balloonet, but because balloonet is too large, the flow of aerating air of blower fan is difficult to meet the demands, and profile returns to from original state during ground to cause dirigible not ensure.
Dirigible adds in the middle part of the inside and outside air bag of extrusome after this structural element, and looking from ground, it is the oblate spheroid that a volume is very little, when stratospheric airship is from ground to stratosphere flight, altitude air is more and more thinner, air pressure constantly reduces, ambient temperature constantly changes, in dirigible utricule, the pressure reduction of gas and ambient pressure can constantly increase, dirigible utricule volume is forced constantly to become large, when arriving 20Km high-altitude, in utricule, the volume of helium will increase to about 14 times that helium volume is filled on ground, outer airbag fold formula extrusome (13) and interior airbag fold formula extrusome (22) just can ensure that dirigible utricule changes with ambient pressure variations, dirigible is made to keep its profile, do not need the large quantity of air of discharging huge " balloonet ", do not need the free air capacity of by-pass valve control simultaneously yet, this two problems solves simultaneously.When dirigible returns to ground, its action principle is contrary.
In force, the flying height that these parts will need according to stratospheric airship designs, how highly require that dirigible flies, can ensure after extending with regard to requiring extrusome to make the volume of interior air bag to reach in interior air bag helium the volume that may reach that expands, guarantee utricule safety, even keep pressure certain inside and outside utricule, to keep the profile of utricule.
This special structural element solves the problem keeping dirigible profile and safety when dirigible flies into safely advection layer and returns to ground from advection layer.
3, this dirigible another distinguishing feature is structurally exactly, and has cast aside the conventional confguration of traditional dirigible main gasbag and forward and backward balloonet, proposes interior air bag overall as the concept among outer air bag.
Be filled with buoyance lift gas in interior air bag, be generally helium or hydrogen; Be full of air between interior air bag and outer air bag, and make gas and outer air bag external environment gas in outer air bag keep certain pressure reduction, so just can ensure the profile of integral gasbag.
Most importantly, we know, traditional dirigible helium leakage is very serious, the dirigible of flight aloft often will descend to supplement helium to ground, makes traditional dirigible hang time very short, and maintenance difficulties increases, consume helium cost to raise, this is one of traditional dirigible deadly defect.
Because air bag in this dirigible is overall as among outer air bag, helium in interior air bag and the pressure reduction between the air between interior air bag and outer air bag are zero, prevent the leakage of helium by pressure balanced method, this is that any raising utricule cloth quality technique is beyond one's reach effect.Applicant once did experiment in the later stage nineties, used pressure balance method that the helium holding time can be made to bring up to about 700% of original conventional balloon, although experiment condition is good not, experimental technique is simple, and result can not be too wide in the gap.The inside and outside airbag structure of visible dirigible will make the hang time greatly improve.
4, in Stress control principle, traditional stratospheric airship is when climbing, and valve cannot meet the needs of huge balloonet venting; When down landing from advection layer, aeration blower fan cannot meet the needs of huge balloonet inflation.
The dirigible of the present invention proposes the concept of minimum air maintenance, makes Stress control become extreme simple.As can be seen from Figure 1, the principle of design of this dirigible is tried one's best in the space between interior air bag and outer air bag little, when ambient temperature raises, dirigible climb ambient pressure reduce time, at one's discretion, in air bag, helium expands with external environment change, because the air between interior air bag and outer air bag is little, even all few than air in traditional low-altitude airship balloonet, even if use traditional dirigible venting valve also can meet the demands completely; When this stratospheric airship lands earthward from advection layer, no matter interior air bag also can meet the demands completely.
5, when dirigible climbs or land need adjustment dirigible pitch attitude time, tradition " stratospheric airship " is the same with low-altitude airship, adopt tailplane and forward and backward balloonet fills, principle of exit control, dirigible is made to come back or bow, but because the front and back balloonet of tradition " stratospheric airship " is huge, be full of an air bag to make it to adjust airship's posture, charging and discharging valve and aeration blower fan are all difficult to meet the demands.This stratospheric airship proposes the method and structure of two kinds of adjustment flight pitch attitudes:
Climb, by interior air bag termination position control rope (14) before interior air bag (2) by interior air bag to pull-up, simultaneously, interior air bag pulls down by air bag (2) interior air bag termination position control rope (14) below, and whole utricule will be adjusted attitude by interior air bag within tens second time; If falls downward wanted by dirigible, method of operation is contrary.The method relies on than tradition " stratospheric airship " fills to huge forward and backward balloonet, drops a hint, and not knowing will soon how many times.
2) utilize the interior balloon drag-line (29) in interior air bag (2) that balloon (27) in interior air bag is pulled to the rear portion of interior air bag (2), dirigible climbs; Balloon (27) in interior air bag is pulled to the front portion of interior air bag (2), dirigible falls downward.This move, can complete equally within tens seconds.
These two kinds of methods all adopt Flying by wire, do to perform propulsion source, by the switch control rule on control panel in operator's compartment in electric control system with little steering wheel.
Air bag in this dirigible, outer air bag making process are the same with traditional dirigible, adopt heat seal mode.
The job operation of empennage, gondola, power system, various valve, blower fan etc. is consistent with traditional dirigible, but this dirigible adopts double-layer horizontal empennage mode, because after in the middle part of (13) in the middle part of outer air bag and interior air bag, (22) trail, the body of dirigible is higher.
For the envelop materials of dirigible, among utricule due to the overall air bag outside of interior air bag, simultaneously, during air bag work, utricule external and internal pressure is equal, within the envelop materials of air bag mainly emphasize iris action to helium and intensity, toughness aspect, not high to the performance requriements of anti-adverse environment, therefore can use the material that density is lighter; And outer air bag is owing to only needing sealing air, do not require emphasis to the iris action of helium, the performance of the intensity that only requires emphasis and anti-external environment condition, so both emphasized the iris action to helium relative to the envelop materials of tradition " stratospheric airship ", emphasize again the performance to intensity and anti-external environment condition, its weight and cost will reduce greatly.
Fig. 4 is view when dirigible adopts interior air bag termination position control rope (14) control dirigible to climb in Fig. 1.
Fig. 5 is view when dirigible rises to that about 10Km is flat to fly in Fig. 1, and in the middle part of outer air bag, in the middle part of (13) and interior air bag, (22) trail about half.As can be seen from Figure 5, the extrusome structure of dirigible, makes dirigible less in ground volume; In high-altitude, it is vertical structure, will resemble a skyscraper, different from the structure that traditional dirigible recumbency flies; In actual production technique, even if used dirigible, if needed, it can increase stretchable layer equally in the middle part of utricule with bottom utricule top or utricule, to increase bag volume.Namely this dirigible is different from traditional dirigible, it can carry out the amendment of increase volume to finished product dirigible as required, concrete grammar is: in the middle part of the outer air bag (13) or interior air bag of dirigible, the top of (22) and interior air bag or bottom boundary separate, then, first calculate and will increase how many Kg load, calculate increase one deck again and can increase how many Kg load, more as required, determine the number of plies increasing stretchable layer in the middle part of air bag.
Fig. 6 is that in one of the present invention, air bag adopts air bag in twist-type telescopic body, outer air bag adopts the example structure schematic diagram of the external air bag of twist-type telescopic, this dirigible and the dirigible in Fig. 1 are consistent in principle, only made whole extrusome structure into twist-type telescopic body, all job operations are consistent with dirigible in Fig. 4.
The present invention is very flexibly in the design and use of telescopic interior air bag and telescopic outer air bag, inside and outside air bag all can adopt the extrusome structure of same form, also can air bag in Foldable telescopic body be placed among the external air bag of twist-type telescopic, also can air bag in twist-type telescopic body be placed among the external air bag of Foldable telescopic; The no matter inside and outside air bag of extrusome of which kind of version, top, the bottom of its inside and outside air bag and middle part can not adopt as required, part adopts or all adopt Foldable telescopic body structure or spiral expanding body structure; Some dirigible utricules also can not arrange in the middle part of interior air bag, in the middle part of outer air bag or in the middle part of inside and outside air bag as required and not arrange.
Fig. 8 is exactly that the present invention's one to adopt in part extrusome in air bag top, part telescopic bottom air bag, bottom the outer air bag top of part extrusome, the outer air bag of part extrusome, adopt a kind of example structure schematic diagram in the middle part of the inside and outside air bag of whole extrusome simultaneously.
In Fig. 8, inside and outside extension airbag all have employed accordion structure, the top of inside and outside air bag all adopts extrusome structure at lower part, and the bottom of inside and outside air bag all have employed extrusome structure at the first half, design is mainly in order to reduce academician's volume and install the needs that pitch attitude adjusts control convenience like this.
In Fig. 8, steering wheel (29A) during pitch attitude adjustment controls is as long as balloon (27) in interior air bag just can pull by very little power very soon back and forth, in supposing, in air bag, balloon (27) has been moved to after interior air bag, light before heavy after dirigible, namely head lifts, even if rudder face is failure to actuate, driving engine does not turn to, dirigible also can upwards climb, and by before in interior air bag, balloon (27) is moved to, dirigible is just adjusted to touch down attitude.
Fig. 7 is a kind of dirigible pitch attitude adjustment control method of the present invention, its purposes, usage and processing mode are described above, wherein, in interior air bag, balloon (27) need use and have larger elastomeric envelop materials, and interior balloon net (28) can the higher nylon material of working strength; Interior balloon drag-line (29B) can the higher Nilong rope of working strength, and the rear and front end of interior balloon drag-line (29B) must install pulley additional; Steering wheel (29A) is as long as be contained in any one end of drag-line.
Should illustrate, stratospheric airship emphasizes the quality and weight of utricule very much, accomplish this point, enterprises preferably will carry out GJB9001 qulity management system, from design, the production of product, test, examination of taking a flight test, gate of the quality monitoring to be maintained strict control over everywhere, need raw MAT'L and the parts of test, must could be gone up to the sky by test, if particularly manned stratospheric airship will be produced, also will carry out according to aircraft production and administration pattern.
