Abstract

The utility model relates to an intermittent backward throw type hail-proof combined rocket shrapnel for rainfall, which is composed of a self-destruction device 1, an engine, a tail fin 6 and an inertia flying body 17. A separating mechanism is arranged in front of the engine, and is connected with a shrapnel cabin 11; the separating mechanism makes the engine disengaged from the bullet cabin 11 after the work of the engine is ended, to achieve that the burning shrapnels are thrown backwards and the diameter of a rocket shrapnel and flying resistance forces are reduced. The utility model has the advantages of large airspace for loading and throwing, the great increase of catalyst, short operating time and low cost.

Description

Intermittent after tow type hail-proof and rain rocket shrapnel

The utility model is used for the hail suppression rainfall operation of weather modification, belongs to civilian free rocket.

Disaster caused by hail can bring heavy losses to agricultural production, and this is on record, and the influence of drought is more extensive, and not only to agricultural production, when serious industrial production and people's lives is caused heavy losses.Therefore, hail suppression rainfall operation then becomes an important topic of weather modification scientific domain.In the present prior art, preferably as: " crystal " of the Soviet Union be rocket (Kpucmall), this technology is that the pyrotechnic compound that contains catalyst is made bullet, the internal weapon bays of dishing out after lighting, bullet is packed into along the arranged radially of rocket in the bullet cabin of head, and the bullet side direction is dished out, because the length of bullet is limit, the diameter of rocket can not be very little, and that therefore the rocket diameter certainly will be designed is bigger, (" crystal " rocket diameter of the Soviet Union is 82mm).Must cause bigger flight resistance loss like this, just can be transmitted into predetermined height, thereby make the throw-weight of rocket increase cost up so require that more propellant is housed.And the reaction force that side is thrown has certain interference to the flight of rocket.

In order to overcome above-mentioned deficiency, the utility model provides a kind of can make bullet by the intermittent after tow type hail suppression rain rocket shrapnel of dishing out later the engine jettisoning, has reduced the rocket diameter, has reduced cost.

Concrete structure of the present utility model is provided by accompanying

drawing

1,2,3.

Fig. 1 is an intermittent after tow type hail suppression rain rocket shrapnel overall schematic.

Fig. 2 is the generalized section of intermittent after tow type hail suppression rain rocket shrapnel.

Fig. 3 is the structural representation of intermittent after tow type hail suppression rain rocket shrapnel coasting flight body.

Principal organ is among the figure: self-desttruction equipment 1, and motor body 2 is isolated powder column 3, the middle end 4, starting mix 5, empennage 6, break pin 7, timer delay to manage 8, release sleeve 9, impelling cartridge bag 10, bullet cabin 11, incendiary bullet 12, separate cartridge bag 13, cavity 14, powder column 15, empty tube 16, coasting flight body 17, bullet delay to manage 18, the preceding end 19, medicine cake 20, engine ignition medicine box 21, ignition lead 22.

Below in conjunction with accompanying drawing the utility model is described in detail.

This intermittent after tow type hail suppression rain rocket shrapnel is by self-desttruction equipment 1, the motor body 2 of powder column 15 is housed, empennage 6, bullet cabin 11 is formed, the end 4 in the middle of motor body 2 front ends are equipped with, bottom, the middle ends 4 is equipped with taper along axis direction and is isolated powder column 3, isolate powder column 3 pre-installed starting mixs 5, adjacent starting mix 5 is equipped with in the cavity 14 of front end of the middle ends 4 and separates cartridge bag 13, front end of the middle ends 4 is with the release sleeve 9 that links to each other with bullet cabin 11, the cavity 14 at the end 4 is equipped with timer extension pipe 8 in the middle of release sleeve 9 upper edges, in the tube chamber 16 of release sleeve 9 front ends impelling cartridge bag 10 is housed, the release sleeve 9 outer bullet cabins 11 that are with, release sleeve 9 links to each other with bullet cabin 11 by the break pin 7 and the middle end 4, between release sleeve and the end, centre and the bullet cabin for movingly, at least 15 incendiary bullets 12 of packing in the bullet cabin, the head in bullet cabin is equipped with self-desttruction equipment, and the entity design of rocket projectile diameter is 37mm.

During use, when solid propellant rocket after hours, it has made rocket obtain to reach the necessary speed of predetermined altitude, the task of being it is finished, if it continues to fly down with head, can increase aircraft drag suddenly, make and penetrate high decline, and the back throwing can't be realized.Therefore, the present invention adopts separating mechanism, behind end of burning, finishing the work, and will become the burdensome engine structure of flight jettisoning immediately, making remainder is that coasting flight body 17 flies alone, throwing bullet for the back creates conditions, and, flight resistance is reduced significantly with less caliber flight, receive the effect of killing two birds with one stone.

The operation principle of this carrier rocket is as follows: when the solid propellant rocket ignition operation, isolate powder column 3 and also take fire simultaneously.When the rocket engine end-of-job, isolate powder column and also just in time also lighted starting mix 5 simultaneously by after-flame, starting mix is lighted separating cartridge bag 13 again, cut off the break pin that connects the middle end and release sleeve by the powder pressure that separates the cartridge bag generation, lighting timer simultaneously delays to manage, at this moment the coasting flight body separates under the air drag effect of separation gas pressure that cartridge bag produced and engine generation fully, and the coasting flight body begins unpowered flight alone.Just in time the coasting flight body reaches the operation cloud layer when timer extension plumber does to finish, the impelling cartridge bag 10 that adorn in the release sleeve front end tube chamber this moment is lighted, the pressure that the gunpowder outburst forms is cut off remaining break pin and release sleeve 9 is dished out, at this moment lighted bullet again and delayed to manage 18, the working time of bullet extension pipe is the defer time of bullet impelling.When doing to finish, bullet extension plumber just the impelling cartridge bag between bullet is lighted the internal weapon bays of under the gaseous-pressure effect, submunition cake 20 being lighted and simultaneously bullet is dished out.Meanwhile again the bullet extension pipe of next bullet is lighted, so repeatedly till all bullet impellings are finished.And last bullet is lighted self-desttruction equipment when being dished out, and makes the self-destruction of coasting flight body.

The present invention has following advantage:

1, catalyst to sow the spatial domain very big.

2, the single-shot rocket can carry considerable catalyst, thereby makes the cost of the unit's of carrying catalyst weight very low.

3, the each operation rocket that only need launch very few number gets final product.

4, the activity duration can shorten dramatically, and this has very important significance for sleet-proof work.

5,, can make single-shot cost of the present invention more much lower than side throwing formula because available less caliber is realized the bullet impelling.
