Abstract

For the non-destructive recovery of high-speed flying bodies, the resistance model of flying bodies through soft media was established. The non-destructive recovery device was designed with polyurethane foam that can clearly leave marks as the soft recovery media material. The 7.62 mm and 14.5 mm projectiles were used to simulate high-speed flying bodies for shooting tests, and the non-destructive recovery of 7.62 mm projectiles was achieved within a distance of 3.2 m. The experiment obtains the variation of the distance, speed, and overload of the flying body through the soft medium with time, and obtains the characteristic parameters of the flying body through the soft medium; the space attitude of the flying body passing through the soft medium is obtained by observing the traces of the flying body retained on the surface of the soft recovery medium.

Key words： high-speed flying body; non-destructive recycling; dielectric material; trajectory
