The invention belongs to the field of
projectile tests and experiments, and particularly relates to a test
projectile recovery device. Partial liquid is filled in a
recovery capsule, a large number ofliquid bubbles can be formed through the links such as a high-pressure air
pipe, a
metal air
pipe, a one-way valve, an air inlet hole and an
open cell foam inner cylinder by utilizing high-pressure gas in a
gas cylinder, the liquid bubbles enter the
recovery capsule, and the liquid containing the large number of liquid bubbles becomes compressible liquid. When a test
projectile rushes into the liquid containing the large number of liquid bubbles at high speed, by utilizing the
compressibility of the air bubbles and the damping characteristic of the liquid, the damage of the projectile causedwhen the projectile enters water is prevented, a speed reducing function of the projectile is realized, and a high-
speed test projectile
recovery function is realized. The test projectile recovery device provided by the invention overcomes the defects of sand box recovery, mechanical buffer recovery, foamed aluminum recovery, water damping recovery and gas recovery, provides a new method for the recovery problem of the projectile experiment process, has a certain value on recovery during the projectile experiment, and is worth to be popularized in the projectile recovery technology.
