The destruction of waste ammunition is of great significance to eliminate the hidden dangers of explosion accidents.Based on the safety requirements of blasting destruction of various waste ammunition found in civil construction, a small shaped charge destruction device is designed by using the principle of impact detonation of shaped charge to shelled charge. Considering the requirements of size, power and field adaptability, the structural parameters of the destruction device are optimized and determined, and the static armor-piercing and impact detonation simulation projectile body tests are carried out. The test results show that the destruction device has strong impact detonation ability, high reliability for common waste ammunition, and is easy to set up and use, which can provide a reference for the design of similar devices.
