In order to assess the safety of the explosive anti-riots munition, proceeding with the pellet fragment’s force condition was analysed in the flying process, the trajectory model of the pellet fragment for the explosive anti-riots munition was deduced, the trajectory curve of the pellet fragment were calculated and analyzed also. The results show that the air resistance and the gravitation have a significant impact on the movement of the pellet fragments, and the former is more obvious than the latter.

Anti-violent rocket on small UAV creatively combines the anti-riot shell with the UAV,utilizing the theory of rocket lanching,realizing that Anti-violent Shell is launched far in the sky.It is significant for CAPF to realize variety of targets battle in the emergency and mission. This paper focuses on sumulation and testing of anti-violent rocket engine on Small UAV,and the flight test-fired experimental of engine is carried on with control system,which demonstrates its feasibility.
