Flight Demonstration of Novel Atmospheric Satellite Concept

The Dual-Aircraft Platform (DAP) is a Phase II NASA Innovative and Advanced Concepts (NIAC) research effort investigating a novel concept for achieving a low-cost atmospheric satellite in the lower stratosphere which utilizes a combination of wind and solar energy capture. DAP consists of two glider-like unmanned aircraft connected via a thin, ultra-strong cable. Long duration flight simulations have shown the platform could literally sail without propulsion, using levels of wind shear persistently found near 60,000-ft, and substantially increase the energy available for useful payload operations. The central objective of the Phase II effort is to perform autonomous proof-of-concept flight demonstrations of the DAP concept using a small-scale prototype at low altitude. Related objectives are developing specific flight maneuvers and mechanisms required for station keeping and validate the autonomous guidance and control software.
