Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

As shown in figure 1, the utility model provides a special artificial snow-increasing rocket for spreading catalyst at low altitude (0.5 km-3 km) based on BL-1A type rain-increasing rocket in 9394 factory in Jiangxi, which comprises a catalyst spreading system 1, a self-destruction system 2, an engine 3 and a tail wing 4. Wherein the catalyst spreading system 1 is sleeved at the head part of the self-destruction system 2 and is fixed by adhesive. The tail part of the self-destruction system 2 is arranged at the head part of a shell 8 of the engine 3, so that the connection between the engine 3 and the self-destruction system 2 is realized. The tail fin 4 is bonded to the rear portion of the engine 3 by an adhesive.

The engine 3 is composed of an engine igniter, an engine charge and a housing 8, and the engine charge is ignited by the engine igniter to burn to generate thrust of rocket flight.

As shown in fig. 2, the catalyst spreading system 1 is composed of a hood 6, a catalyst delay igniter 7, and a catalyst charge 5. The catalyst spreading system 1 is sleeved at the head of the self-destruction system 2 through a hood 6, and the catalyst delay igniter 7 is used for spreading the catalyst within a preset height range (0.5 km-3 km) through delay time control, so that the catalyst and a cloud layer are promoted to perform sufficient micro-physical reaction, and the snow increasing effect is improved.

The self-destruction system 2 consists of a self-destruction delay igniter, a self-destruction medicament and a self-destruction medicine box, wherein the self-destruction delay igniter ignites the self-destruction medicament to realize that the rocket is self-destroyed in the high altitude, and the remains fall off in the form of floccules not larger than 100 g.

Fig. 3 is a block diagram of the working principle of the rocket dedicated for artificial snow enrichment according to the embodiment of the present invention, the catalyst spreading of the rocket is to control the catalyst start-up time through the catalyst delay igniter 7, and the delay of the catalyst delay igniter 7 is to realize the control of the delay time through the combustion of the delay agent assembled inside. In order to reduce the delay time from 12s of the original BL-1A rain-increasing rocket to 2s, the delay time can be realized by reducing the loading of delay agents. By changing the loading of the delay agent, the catalyst delay igniter 7 can reliably ignite and stably burn the catalyst 2s after the rocket is ignited, and the catalyst is spread.

As shown in figure 4, a first-stage delay tube 9 is arranged beside a self-destruction delay igniter 10 of the self-destruction system 2, the input end of the first-stage delay tube 9 is aligned with a catalyst spreading end, and the output end of the first-stage delay tube is aligned with a self-destruction medicament in a self-destruction medicament box. As the self-destruction control of the self-destruction device 2 is a double-channel working mode of the ignition of the self-destruction delay igniter 10 and the first-stage delay tube 9, the self-destruction device 2 starts to work as long as the self-destruction delay igniter 10 and the first-stage delay tube 9 have one output flame, thereby realizing the self-destruction. The self-destruction delay igniter 10 controls the working time through the built-in delay medicament, the delay medicament starts to work when the rocket bomb starts to ignite, and the delay time of the output flame is 24 s. The medicament combustion of the first-stage delay tube 9 needs to depend on flame when the catalyst starts to be spread, and then the medicament combustion in the delay tube realizes delay, so that the time from the starting of the rocket bomb to the outputting of the flame by the first-stage delay tube 9 comprises two parts, one part is the time when the catalyst starts to be spread, and the other part is the delay time when the medicament of the first-stage delay tube 9 is combusted. Because the spreading time of the modified snow-enriched rocket is reduced by 10 s (the spreading time of the original BL-1A type rocket catalyst is 12 s) compared with the spreading time of the original BL-1A type rocket catalyst, the delay time of the self-agent combustion of the first-stage delay tube 9 is 22 s (10 s is increased on the basis of the original 12 s) to ensure that the rocket projectile self-destruction delay igniter 10 and the first-stage delay tube 9 output flame 24 s after the rocket projectile is ignited to realize the rocket self-destruction.

In order to realize that the catalyst is scattered in 2s without changing the self-destruction time, the delay time of the catalyst delay igniter and the delay time of the first-stage delay tube 9 need to be changed on the original BL-1A type rocket projectile, and other indexes are not changed. The modification of the two is realized by modifying the charging amount of the delay medicament, so that the delay time of the catalyst delay igniter is 2s, and the delay time of the first-stage delay tube 9 is 22 s.

In conclusion, with the aid of the technical scheme of the utility model, realize through the control of delay time that the catalyst scatters the catalyst at predetermined altitude range to promote the catalyst and carry out abundant little physical reaction with the cloud layer, improve the snowing effect.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
