| 摘 要： | 故障无人机地面滑跑起飞时的运动特性与正常无人机不同。描述了无人机两轮起飞滑跑的过程,通过详细分析方向舵卡死在固定角度时,无人机两轮滑跑的受力情况,建立了纵向和侧向的非线性动力学方程。并在此基础上通过无人机的安全起飞要求和最小离地速度,确定了使无人机可控的方向舵最大卡死角度。最后以某型飞机为例进行计算,结果证明本文分析的有效性。为故障无人机起飞安全提供了理论依据,对控制律的设计具有重要的指导作用。

| Abstract: | In the course of taxiing takeoff,the faulty UAV has the unique dynamical characteristics in ground motion different from normal UAV.The process of a UAV during two-wheel take off and taxiing is described,the strength pressed on the UAV in the course of two-wheel taxiing is analysed when rudder is locked in place,and the longitudinal and the lateral dynamic equations are established.The authority of rudder finite locking is determined through the safety take-off requirement and the minimum lift off speed.Fin... |
