摘要:

针对运载火箭子级可能影响空中回收直升机飞行安全的问题,通过仿真研究了在空中钩取运载火箭子级时直升机飞行轨迹和缆绳拉力的变化情况。首先,建立直升机及火箭子级的运动模型;然后,设计直升机升力和缆绳拉力反馈控制,并采用粒子群优化(particle swarm optimal, PSO)算法在给定约束条件下整定反馈参数;最后,通过仿真求得了钩取过程中缆绳拉力的变化和直升机飞行轨迹的扰动。空中钩取时直升机的飞行速度是影响缆绳最大拉力和长度的主要因素;主动控制缆绳的收放,能够有效缓冲空中钩取导致的冲击载荷,缆绳越长,最大拉力越小。研究结果表明,文中提出的钩取方法可以保证直升机飞行安全。

Abstract:

In view of the potential issue that launch vehicle stages may affect the flight safety of aerial retrieval helicopters, the changes of helicopter flight trajectory and pull force of the rope when hooking a launch vehicle stage in air are studied by simulation. Firstly, motion equations of helicopter and rocket stage in flight profile are built. Secondly, feedback control laws for helicopter left force and pull force of rope are designed. The feedback parameters are optimized under given constraints by the particle swarm optimization (PSO) algorithm. Finally, the variations in pull force of rope and disturbances in helicopter trajectory during the hooking process are obtained by simulation. The helicopter flight velocity is the key factor for maximum rope pull force and length when hooking in the air. The impact load acting on helicopter when hooking in the air can be effectively eliminated through actively controlling the length of rope. The longer the rope, the smaller the maximum pulling force. Research results indicate that the hooking method proposed in the paper can ensure the safety of the helicopter flight.
