摘　　要：针对小型无人直升机动力失效后的自转着陆问题,建立了直升机自转飞行动力学模型。根据直升机自转飞行过程中的下降速度变化,将飞行过程分为加速下降、稳定下降和减速着陆3个阶段,设计了相应的控制策略。仿真结果表明,该模型具有较高的精度,实现了直升机自转飞行的安全着陆。研究成果对小型无人直升机自转飞行的研究具有一定的参考意义。Aiming at the autorotation landing problem of small unmanned helicopter after power failure,a helicopter autorotation flight dynamics model is established.According to the change of descent speed during helicopter rotation flight,the flight process is divided into three stages:accelerated descent,stable descent and deceleration landing,and the corresponding control strategy is designed.The simulation results show that the model has high accuracy,and achieves the safe landing of helicopter rotation flight.The research results have some reference significance for the research of small unmanned helicopter rotation flight.
