Power management for landing an unmanned aerial vehicle with vertical lift rotors. In an example, an unmanned aerial vehicle (UAV) is disclosed that includes an avionics system, a propulsion system, a vertical lift rotor, and a controller. The controller performs operations including, in response to detecting that the propulsion system is out of operation, determining energy and time constraints based on (i) a remaining avionics battery life and (ii) a remaining rotor battery life. The operations further include evaluating parameters of a glide descent trajectory and a subsequent rotor powered flight trajectory to a candidate landing point using a rotor edgewise inflow model stored on the controller, to determine whether the estimated energy consumption during the rotor powered flight trajectory and the time required for the UAV to land at the candidate landing point exceed constraints based on the evaluation of the parameters. The operations further include selecting an alternative candidate landing point in response to determining that the estimated energy consumption and the time required exceed the energy and time constraints.
使具有垂直提升旋翼的无人驾驶飞行器着陆的电力管理。在示例中,公开了一种无人驾驶飞行器(UAV),该UAV包括航空电子设备系统、推进系统、垂直提升旋翼和控制器。控制器执行包括以下操作:响应于检测到推进系统失去操作,基于(i)剩余航空电子设备电池寿命和(ii)剩余旋翼电池寿命来确定能量和时间约束。所述操作还包括:使用存储在控制器上的旋翼沿边流入模型,评估到候选着陆点的滑翔下降轨迹和后续的旋翼供电飞行轨迹的参数,以基于对参数的评估来确定旋翼供电飞行轨迹期间的估计能量消耗和UAV着陆在候选着陆点处所需的时间是否超过约束。所述操作还包括:响应于确定估计能量消耗和所需的时间超过能量和时间约束,选择另选候选着陆点。
