چکیده
Abstract. In order to research the air burst dispersion (ABD) of a new multiple launch rocket system, a simulation method is presented in this paper, which is concentrate on analyzing the influence of various random factors on ABD. First a launch dynamic model is established to simulate the initial disturbance that affected by impact force of gas. Then the influence of combustion-gas flow upon back projectile is analyzed with the impact force model of combustion-gas flow in ballistic coordinates system. Finally, the simulation result of ABD is obtained by solving the extern trajectory equations with Monte-Carlo method. The simulation result is validated by experimental data and shows that the simulation models are accurate and credible.
