A device for ejecting a rod-shaped projectile after high-speed impact

This invention relates to a projectile ejection device suitable for high-speed impact experiments with rod-shaped projectiles, comprising a sabot system and an ejection system. The sabot system is used to mount the rod-shaped projectile and allow it to be positioned along the axial direction of the gun barrel. The ejection system includes a collection bucket, a buffer pad, and an interceptor. The end of the collection bucket away from the sabot system has a baffle with a first through hole in its center. The buffer pad is disposed inside the collection bucket and abuts against the baffle, and has a second through hole. The first and second through holes are coaxially aligned and continuous. One end of the interceptor is embedded in the second and first through holes, and the other end has at least two spaced buffer layers along its axial direction. The interceptor has a through-channel for the rod-shaped projectile to pass through. This design allows the sabot system to completely separate from the rod-shaped projectile without affecting its original flight attitude, ensuring the projectile is ideally isolated when passing through the magnetic velocity measurement test area and impacting the target.
