Therefore, the initial speed of the cannonball is not affected, and the pressure in the explosive chamber pipe is unloaded, so that the recoil of the cannonball body when the cannonball is launched can be greatly reduced.

The operating principle of the recoil inhibition carbon dioxide gun launching device is as follows:

after the liquid carbon dioxide in the medicine chamber pipe 4 is controlled to detonate by the conventional detonating device, the liquid carbon dioxide is changed into gaseous carbon dioxide, the gas in the medicine chamber pipe 4 rapidly expands, the pressure in the medicine chamber pipe 4 rises, when the pressure rises to a certain value P1, a rupture disk in the deep pipe 1 is broken, the pressure pushes the cannonball 16 to advance, the pressure continues to rise, when the pressure rises to a pressure value P2, the force of pushing the medicine chamber pipe 4 backwards by the pressure of the medicine chamber pipe 4 is greater than the hydraulic pressure of the hydraulic jack 5 (namely the product of P2 and the action area is greater than the product of P3 and the action area), the hydraulic jack 5 retreats under the backward pushing force of the medicine chamber pipe 4, the sealing ring 8 at the end part of the medicine chamber pipe 4 moves backwards, the pressure relief channel 15 between the medicine chamber pipe 4 and the breech 2 is opened, the gas is released, and the medicine chamber pipe 4 is unloaded; in the process, the pressure is reduced due to the principle of the expanding wave (one of the basic concepts of fluid mechanics, namely, the interface exists between a disturbed area and an undisturbed area in a fluid, and the pressure is reduced when the fluid passes through the interface). A typical example of the problem of the expanding wave is the constant flow of supersonic airflow around a convex angle, which is called the Plantt-Meyer flow, in the flow, the airflow gradually turns from one direction to the other direction and is accelerated, the pressure in the deep tube 1 is gradually unloaded from the breech 2 to the muzzle, and finally, when the cannonball 16 is discharged, the pressure is unloaded to the port of the deep tube 1, the initial speed of the cannonball is not influenced, the pressure in the chamber tube 4 is unloaded to a great extent, and the recoil is unloaded to a great extent, so that the recoil when the cannonball is launched is greatly reduced.

The invention provides a carbon dioxide gun launching device with a novel principle by adopting an expansion wave principle, and realizes effective inhibition of recoil of an explosion device.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
