This final report documents the Helicopter Payload Position Sensors Program. This program was an 8-mo investigation of techniques for determining position and motion of helicopter slung loads. Initial program tasks included a review of slung load dynamics due to 1 aerodynamic instabilities in the higher speed range, and 2 vehicle-load interactions during low-speed maneuvers and hover. This review and an analysis of current and projected load stabilization concepts, provided the basic performance requirements for the payload position sensor. The investigation included the influence of suspension systems configurations and load types.
