In this embodiment, the high-pressure gas-driven automatic-loading launching device is mounted on the rotating rack in a manner that the magazine faces upward. The rotating rack is arranged on the rack base, and the automatic loading and launching device deflects up and down through the rotation of the planetary reduction gear rotating rack and the worm gear. The magazine mounting hole is connected to a magazine gas supply hole of a rotary gas supply valve by a magazine hose, and ammunition in the magazine hose is fed into the gun body by high-pressure gas. The air inlet end of the main air supply pipe is connected with a high-pressure air cylinder, and the high-pressure air cylinder is connected with an air compressor or an aircraft engine through an 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 arranged on the section of pipeline.

When the rotary air supply valve works, the air leakage hole of the rotary air supply valve is aligned with the air leakage hole of the piston cavity, so that no air exists in the piston cavity; the electromagnetic valve is in a closed state before the inlet of the air supply hole is triggered; the projectiles within the magazine hose are constrained within the magazine by the ball-top screw of the magazine. When the high-pressure gas cylinder is opened, the required high-pressure gas of 8Mpa flows in from the main gas supply pipe, and no gas flows in from the percussion gas supply hole because the electromagnetic valve is in a closed state. The rotary gas supply valve rotates, the gas supply hole of the rotary gas supply valve is firstly aligned with the gas supply hole of the magazine, the rotary gas supply valve stays for a short time at the angle, and the shot in the soft tube of the magazine is impacted by high-pressure gas to extrude the ball-ejecting screw of the magazine, so that the ball-ejecting screw at the front end of the ball-ejecting screw retracts and then falls into the bore, and then the ball-ejecting screw ejects to prevent the next shot from falling into the bore. The rotary air supply valve continues to rotate, then the air supply hole of the rotary air supply valve is aligned with the air supply hole of the piston cavity, the rotary air supply valve stays for a short time at the angle, the piston cavity of the gun body is inflated, the sliding sleeve is pushed to the front by overcoming the action of the return spring until the sealing inclined surface of the sliding sleeve is contacted with the sealing inclined surface of the inner wall of the gun bore. In the process of forward movement of the sliding sleeve, the shot falling into the gun chamber is pushed to the ball-ejecting screw of the gun chamber by the sliding sleeve for fixation, and meanwhile, the sliding sleeve also has a sealing effect on the magazine to prevent the shot from falling. The automatic loading process is now complete. And the rotary gas supply valve continues rotating, before the rotary gas supply valve is rotated to align the gas release hole of the rotary gas supply valve with the gas release hole of the piston cavity, the control system opens the electromagnetic valve, high-pressure gas of 8Mpa flows in from the percussion gas supply hole, and the electromagnetic valve is closed. The ball-ejecting screw of the gun chamber fails under the action of high-pressure air, the shot is ejected at high speed, and the ball-ejecting screw of the gun chamber is reset. When the air release hole of the rotary air supply valve is rotated to be aligned with the air release hole of the piston cavity, high-pressure air in the piston cavity is released, the sliding sleeve moves backwards under the action of the reset spring, the sealing effect on the magazine is relieved, and the next loading process is facilitated. A complete set of loading and firing processes is completed.
