摘要
对于内装式空中发射方案,箭机分离过程中可以采用阻力伞稳定运载火箭点火前的姿态。针对这一过程,利用凯恩方法建立了箭伞系统的9自由度动力学模型,并编制了箭机分离过程仿真程序。仿真结果表明,阻力伞可以使运载火箭获得合适的发动机点火时机,并能够有效抑制运载火箭的偏航扰动运动。
For internally carried air-launch method,a drogue chute can be used to stabilize the attitudes of a rocket when it＇s released from its carrier aircraft.In this paper,a nine-degree-of-freedom dynamic model is built for the rocket-parachute system by applying the Kane method,and a computer program is developed to simulate the motion of rocket-parachute system based on this model.The simulation results show that the drogue chute can make the rocket to obtain appropriate conditions for engine ignition and can suppress the yaw disturbed motion of the rocket effectively.
