摘要
海上实施空投时往往对弹体在空中的姿态、入水速度、入水姿态以及落点的散布有着严格的要求。采用减速伞能有效地降低弹体的速度并能迅速调整弹体的姿态,研究带减速伞弹体的空间三维弹道是确定弹体各运动参数的理论依据。本文根据弹伞系统纵平面内运动的动力学简化假设,将弹伞弹道模型拓展为空间三维弹道。通过对弹道模型进行仿真计算,确定了弹伞系统空间运动的形态。本文所建立的带减速伞弹体三维弹道模型有效地解决了空投弹伞弹道的仿真问题。
We generally have strict requests for the missile＇s posture, speed, and the dispense of the fall point when aerial-launches on the sea. The parachute can effectively decelerate and adjust the posture of the missile. The 3D trajectory model is the theoretical basis of missile with parachute. By the simplified assumptions of vertical plane motions, this paper created a 3D trajectory model for the missile with parachute. The result of the simulation provided parameters of missile with parachute we need. The simulation model created in this paper is effective for the research on missile and parachute＇s movement.
