Abstract

The invention discloses an ejection device for an air cannon. The ejection device comprises an ejection system and a stabilizing system. The ejection system comprises flange plates, multiple sliding rods, muzzle brakes, springs and nuts. The flange plates are connected with a muzzle of the air cannon, one end of each sliding rod is connected with the corresponding flange plate, the other end of each sliding rod is connected with the corresponding nut, the muzzle brakes penetrate the corresponding sliding rods and are arranged between the corresponding flange plates and the corresponding nuts,and the springs penetrate the corresponding sliding rods and are arranged between the corresponding muzzle brakes and the corresponding nuts. The stabilizing system comprises a shell support and a guide tube, wherein the shell support is arranged in a gun tube. A shell opening for containing a shell is formed in the end, in the muzzle direction, of the shell support. The guide tube is arranged atthe tail of the shell. The guide tube is connected with the shell. A guide hole for containing the guide tube is formed in the tail of the shell opening. By means of the ejection device for the air cannon, the flying posture of the shell after being separated from the shell support can be stabilized.

Description

technical field [0001] The invention relates to the technical field of air cannons, in particular to an ejection device for air cannons. Background technique [0002] In the study of structural protection, the research on the anti-penetration performance of structures under the impact of non-explosive shrapnel or projectiles is an important direction of anti-damage. In the early research, it was mainly for the protection requirements of armored vehicles. With the emergence of various high-performance weapons and the need for higher survivability of structures, this problem is becoming more and more important in the field of aeronautical structural engineering. Such as the anti-ballistic penetration design of the aircraft fuselage and fuel tank. [0003] In the field of aeronautical structural engineering, with the continuous development of civil aviation, the increasing flight envelope of aircraft, and the widespread application of composite materials on aircraft, the risk...
