摘要
针对以往对雷伞系统入水参数分析时,只考虑了投雷速度、投雷姿态角以及风速,存在对影响因素考虑不全、不深入等不足的情况,该文建立了雷伞系统三维空间弹道数学模型,对鱼雷的空中弹道进行了仿真计算,并根据仿真结果分析了投雷高度及速度、姿态角、降落伞设计参数以及气象风等对雷伞系统入水参数及弹道稳定性的影响,并得出了有意义的结论,可为空投试验及射表编制提供技术支持。
For the water entry parameters analysis of torpedo-parachute system, the existing studies only considered torpedo＇s dropping speed, attitude angle, and wind speed, but neglected other factors. This paper establishes a three-dimensional space trajectory model of torpedo-parachute system, and simulates torpedo trajectory in air. According to the simulation results, the influences of the comprehensive factors on water entry parameter and trajectory stability of the torpedo-parachute system are analyzed, and some valuable conclusions are drawn. Those factors include dropping altitude, speed and attitude angle of a torpedo, design parameters of a parachute, and wind speed. This research may provide a technical support to air drop test and firing form scheduling of torpedoes.
