The launching device system is a main body part of a launching system, is a high-overload kinetic energy launching system, and uses compressed air to replace high-pressure gas generated by the combustion of traditional gunpowder to complete the launching of the shot according to the similar principle of dynamics. When the projectile is launched, the quick-opening valve is quickly opened, the gas pressure is directly applied to the bottom of the projectile, and the projectile is accelerated to obtain certain kinetic energy and then is ejected from a muzzle. The design of this scheme has fully combined 25mm bore principle model machine design experience in the past, simultaneously according to the requirement of using under the space environment to satisfy the muzzle initial velocity that the index required and be the design basis, accomplish structural security, reliability simultaneously, and accomplish the best optimization of structure on this basis again, in order to guarantee lightweight, miniaturization, the modularization of product.

The quick-opening valve is arranged between the high-pressure air chamber and the inner cavity of the bullet supply section 6 and used for closing the front-end outlet of the high-pressure air chamber to isolate air or quickly opening the front-end outlet of the high-pressure air chamber to communicate the high-pressure air chamber with the inner cavity of the bullet supply section 6.

Specifically, the launching tube is mainly used for completing a launching task of the projectile, and the projectile is pushed by air pressure after being opened through the quick opening valve and accelerated in the gun tube until certain projectile kinetic energy is obtained, and then is ejected from a gun muzzle to complete a launching action. The launching tube is made of high-strength aluminum alloy materials, the bearing in the bore is considered, and the wall thickness of the barrel is reasonable. As shown in fig. 11 and 12, the launching tube 13 comprises a launching barrel and a line bore barrel, one end of the launching barrel is connected with the ammunition supply section 6 of the ammunition supply mechanism, the other end of the launching barrel is connected with the line bore barrel, two reinforcing sections are arranged in the middle of the launching barrel, the whole wall thickness is reasonably reduced while the pressure bearing and strength rigidity of the barrel are ensured, and the mass of the barrel is reduced, and the barrel interface adopts a large-size rectangular threaded connection interface; in order to improve the hitting precision of the launching system, the system also designs a line bore barrel, a plurality of spiral bulges and grooves which form a certain inclination angle with the axis of the barrel are arranged on the wall of the inner bore guide part of the line bore barrel, and the line bore barrel has the function of endowing the shot with a certain rotation speed when the shot goes out of the bore so as to ensure the stability of the shot in the flying process. Meanwhile, the interfaces of the chamber barrel and the launching barrel are kept consistent, so that the chamber barrel and the launching barrel have interchangeability.

Specifically, a quick-opening valve, which serves to isolate gas and open quickly, is usually installed at the front end of the high-pressure chamber. When gas is injected, the quick-opening valve is in a closed state, so that the gas is only injected into the high-pressure gas chamber and does not leak to the transmitting barrel section; when in deflation, the quick-opening valve can be quickly opened, so that a large amount of gas in the high-pressure gas chamber immediately acts on the bottom of the projectile positioned in the projectile feeding section.

At the moment when the projectile is shot out of the muzzle, the projectile has obtained a certain initial velocity kinetic energy. At the moment when the projectile starts to move, the shading quantity is changed through an infrared screen of a first launch correlation ballistic trajectory screen sensor, a first square wave generated by the first sensor is fed back to a controller, the projectile moves through a second launch correlation ballistic trajectory screen sensor, a second square wave generated by the second sensor is fed back to the controller, and the launch time is calculated through the time difference between the first square wave and the second square wave, so that the muzzle initial speed of the projectile is calculated according to a formula.

The launching system optimizes the structural strength and the interface strength while considering the realization of structural functional performance, carries out structural optimization on a local weak structure according to the environmental and mechanical requirements under the space application environment, and leads the whole ammunition supply mechanism to pass the environmental and mechanical requirements required by a space carrying platform.

The launching system controls and releases the high-pressure inert gas, so that the accelerated launching process of the projectile is realized. As the inert gas with high molecular weight is adopted, compared with the traditional gunpowder launching, the gas medium is more single, and the converted kinetic energy is more sufficient due to the high mole number. Meanwhile, the corresponding impact on the launching recoil is small, and the impact on the posture of the system carrying platform is small.

The launching system adopts inert gas as driving energy, the whole launching process can be considered as a cold launching process, and the launching system does not contain an initiating device and has higher reliability and safety.

The launching system adopts the bullet supply mechanism of the vertical bullet disk, the bullet supply mechanism controls the composite action of the bullet poking teeth, the bullets and the bullet drum isolation cover of the bullet drum through the output of a single motor, and the functions of bullet feeding, bullet distribution and bore internal sealing of the bullet supply mechanism are realized.
