Abstract

Abstract

The emission environment can be transformed from water medium to gas medium by water immersion gap-exist launch mode. In order to study the driving impact load of high speed projectile under this condition, the theoretical model of projectile impact load is established. The inlet impact loads of the projectile under different conditions of inlet velocity, head cone angle and inlet attack angle are calculated. The influences of inlet velocity, warhead parameters and inlet angle of attack on driving impact load are analyzed. The research results are of great significance to the prediction of the driving impact load of high-speed underwater projectile and the design of warhead.
- diving impact load,
- inlet veloctiy,
- half cone angle,
- entry angle of attack
