A concept for a Long Endurance Autonomous Powered Paraglider (LEAPP) is developed under a
is considering LEAPP to address various missions with three categories. The largest version will be a slow flying long endurance platform, which could accommodate two men, and be ground transported by a HMMWV. The system will use the largest paraglider wing ever built, spanning over 112 ft. (34 m’) The vehicle will be able to take off from a ground clearing of 50 – 100 ft (15 – 30 m’) or air dropped from C-130 or C-17 from an altitude of 35,000 ft. (10.5 km). LEAPP will be able to stay on a mission for 48 hours and carry mission payloads of up to 200 lbs, in addition to 2,145 lbs (972 kg) of fuel.
A smaller version (LEAPP Type II) will be optimized for shorter missions (u to 24 hours). It will have a gross maximum takeoff of 1,550 lbs (703 kg), compared to 3,000 (1.4 tons) for Type I. It will also be operated aspiloted/pilotless autonomous, and will be able to carry 200 lbs (90.7 kg) of mission payload but significantly less fuel.
The Micro LEAPP (Type III) is a much smaller vehicle, with a maximum gross weight of 75 lbs (34 kg), it will have a payload capacity of 30 lbs (13.6 kg), and mission endurance of four hours. The vehicle can be launched and operated by a single operator. For takeoff, Micro LEAPP requires only 5 – 10 meters of clear surface.
