Accelerating projectile support and method for non-empennage projectile body

The invention belongs to the technical field of ballistic tests and particularly relates to the projectile high-speed loading technology. According to the technical scheme, an accelerating projectile support for a non-empennage projectile body comprises a projectile support body (1) composed of 2-4 clamping petals in a sticking manner and a bottom pusher (4). Stable loading and launching of a launching body tube with the length ranging from 10 mm to 30 mm are adopted for the non-empennage projectile body with the length-diameter ratio ranging from 3 to 7, reliability of high-speed loading tests of the projectile body is improved, and the test cost is lowered. Stretching of the clamping petals and stable separation between the projectile body and the clamping petals are achieved in the projectile flying process through aerodynamic force and an inverted-conical structure at the front end, and a good target touching posture of the projectile body is ensured while the machining difficulty is lowered. Due to the rigid bottom pusher, it is ensured that the projectile body cannot be seated backwards when being launched, chamber pressure directly acts on the bottom pusher, the bottom pusher pushes the projectile support to move through a positive conical face and pushes the projectile body to move through an upper surface, it can be avoided that angles of attack are generated during fragment flying, and damage to the launching body tube can also be reduced; and good universality is achieved.
