导弹外头罩分离及落区预测仿真

Some missiles use head cover to protect the internal equipment during the launching process. In order to prevent the head cover from damaging the people or equipment after separation, researchers need to predict the landing position range and take protective measures. This paper designs a separation scheme for a missile head cover separation based on solid propellant gas generator and solid rocket. In this study, we establish a dynamic simulation model of head cover separation and falling procedure. The simulation calculation of the head cover location range considering multiple factors using Monte-Carlo method is developed. And the motional curve of separation bodies and the danger zone of head cover landing location are obtained. The simulation results in this paper will provide technical support for rocket launcher and personnel protection design.
