Detailed Description
Specific embodiments of the present invention will now be described with reference to the accompanying drawings. The dimensions of the various elements in the drawings are not necessarily to scale, and any description is meant as an illustration and not as a limitation.
Referring to fig. 1 to 4, the piston type multi-bullet serial launching structure of the invention comprises a barrel 1, a medicine chamber 7 and an integral bullet, wherein the integral bullet and the medicine chamber 7 are both positioned in the barrel 1, and the medicine chamber 7 is positioned behind the integral bullet; the integral elastic body comprises a shell 2, an air chamber 8, a piston 9, two elastic belts 4, M elastic balls 3 and N elastic clips 5, wherein M is more than or equal to 2, and N=M; the shell 2 is a thin-walled cylinder, the top surface is an open end, the bottom surface is provided with a bottom cover, and a plurality of vent holes 6 are annularly distributed on the bottom cover; m pellets 3 are sequentially filled in the cartridge case 2 from back to front, and the pellets 3 are connected with the cartridge case 2 through a cartridge clip 5; the two elastic bands 4 are fixed on the outer side wall of the shell 2 at intervals and are matched with the inner wall surface of the barrel 1; the cartridge 5 is used for fixing and positioning the projectile 3; a baffle plate is arranged in the shell 2 to divide the shell 2 into a front cavity and a rear cavity, the baffle plate is positioned behind the projectile 3, and the rear cavity is an air chamber 8; the center of the partition plate is provided with a through hole, the piston 9 penetrates through the through hole, one end of the piston 9 is positioned in the air chamber 8, the other end of the piston is positioned in the front cavity of the cartridge case 2, and the piston 9 moves back and forth along the through hole. According to the piston type multi-bullet serial-connection emission structure provided by the invention, ignition powder is combusted to generate high-temperature and high-pressure gas, so that the integral elastic body is pushed to move forwards in the barrel 1, and is radially restrained when moving in the barrel 1. The high-temperature high-pressure gas enters the air chamber 8 through the vent holes 6 at the tail parts of the integral elastic bodies, so that the pressure in the air chamber 8 is increased, the piston 9 is pushed, and the piston 9 is changed from a buckled state to a unbuckled state. Along with the continuous rising of the pressure of the air chamber 8, the piston 9 is continuously pushed, the piston 9 is changed from the unbuckled state to the buckled state, and the high-temperature high-pressure air enters the front cavity of the cartridge case 2 through the air guide hole on the piston 9, so that the pressure in the front cavity of the cartridge case 2 slowly rises. When the integral projectile flies away from the muzzle and enters water, the internal and external pressure difference of the integral projectile breaks at the connecting notch of the multi-petal projectile, so that the integral projectile is disassembled. After that, the projectile 3 is separated from the shell 2, the projectile 3 moves in water at certain intervals, supercavitation is formed around the serial projectiles, the resistance of the projectiles is effectively reduced, and the resistance of the rear projectiles is greatly reduced. The invention can be applied to drag reduction of an underwater serial navigation body.
