Novel Airframe Design for the Dual-aircraft Atmospheric Platform Flight Concept
註釋"A high-altitude, long-endurance unmanned aerial airframe was designed for the innovative Dual-Aircraft Atmospheric Platform flight concept that exploits stratospheric wind velocity gradients to remain aloft indefinitely. Classical aircraft techniques and high-fidelity tools were used to establish a baseline configuration. The innovative tandem-wing design exhibits exceptional performance characteristics required for the flight concept."--Leaf iv.
