Simulation analysis of the influence of contact state on the damage effect of shaped charge jet

Attack UAV anti-tank operations generally use air-to-ground missile with a shaped charge warhead. In order to improve the damage effect of shaped charge jet, this paper focuses on analyzing the influencing factors of contact state on the damage effect of shaped charge jet, proposing the measurement index of damage effect, studying the simulation methods of damage effect, and finally the simulation analysis of damage effect was carried out. The analysis of the damage effect simulation results shows that, in the range of 45°~90° of the impact angle, the damage effect of shaped charge jet by changing the impact angle is not obvious; the shaped charge jet in the impact speed range of 2km/s~3km/s, the damage effect of shaped charge jet gradually increased with the increasing impact speed.
