In this embodiment, the high-pressure gas-driven automatic loading and launching device is installed on the rotating platform with the magazine facing upward. The rotating gantry is installed on the pedestal base, and through the rotation of the planetary reduction gear rotating the gantry, the up and down deflection of the automatic loading and launching device is realized through the turbine worm. Use a magazine hose to connect the magazine mounting hole to the magazine air supply hole on the rotary air supply valve, and the ammunition in the magazine hose is fed into the gun body by high-pressure gas. The intake end of the main air supply pipe is connected with the high-pressure gas cylinder, and the high-pressure gas cylinder is connected with the air compressor or aero-engine through the air-driven compression pump. The gas from the main gas supply pipe to the firing gas supply hole is controlled by a high-pressure solenoid valve installed on this section of the pipeline.

When working, the vent hole of the rotary air supply valve is aligned with the vent hole of the piston cavity to ensure that there is no gas in the piston cavity; the solenoid valve is closed before the inlet of the air supply hole is fired; the projectile in the magazine hose plays the role of the top ball screw of the magazine is confined to the magazine. Open the high-pressure gas cylinder, the required high-pressure gas of 8Mpa flows in from the main gas supply pipe, and the firing gas supply hole is closed because the solenoid valve is in a closed state, and no gas flows in. The rotary air supply valve rotates, the air supply hole of the rotary air supply valve is first aligned with the air supply hole of the magazine, the rotary air supply valve stays at this angle for a short time, and the projectile in the magazine hose is impacted by the high pressure gas and then squeezes the magazine Screw the top ball to retract the top ball at the front end, and then fall into the barrel, and then the top ball pops up to prevent the next projectile from falling into the barrel.

At this angle, the rotary air supply valve stays for a short time, the piston cavity of the gun body is inflated, and the sliding sleeve is overcome by the action of the return spring. Push forward until the sealing slope of the sliding sleeve is in contact with the sealing slope of the inner wall of the barrel. During the forward movement of the sliding sleeve, the projectiles that fell into the gun bore before are pushed by the sliding sleeve to the top ball screw of the gun to be fixed. At the same time, the sliding sleeve also plays a role in sealing the magazine to prevent projectiles from falling. At this point, the automatic reloading process is complete.
