Safe Emergency Landing Of A Uav
Abstract: Method for autonomous safe emergency landing of a powered unmanned aerial vehicle (UAV) in the event of an engine failure. A landing approach trajectory is generated including a downwind leg initiating at an initiation point of the trajectory an upwind leg terminating at a selected touchdown point and a U turn leg joining between the downwind leg and the upwind leg. The UAV is directed to the initiation point to follow the downwind leg. A glide ratio of the UAV is repeatedly determined based on current flight conditions. A current turning point is repeatedly determined along the downwind leg based on the determined glide ratio the U turn leg initiating at the current turning point. When the UAV arrives at the current turning point the UAV is directed to follow the U turn leg and the upwind leg for landing the UAV at the selected touchdown point.
