This research addresses a deployable wing for a rapid response high altitude long endurance aircraft that is delivered to a high altitude over a location of interest in a low volume stowed configuration. The challenges are multi-disciplinary and relate to aerodynamics, structures, materials and manufacturing technology. The proposed technical approach is a high L/D inflatable wing with a number of innovations, including: the use of thin film materials for low volume storage, the use of structural fiber reinforcement for tailored strength and stiffness characteristics, a design that transfers of tension from the inflatable spar to the wing skin to promote airfoil accuracy, inflatable ribs, and compatibility with a Hydrazine-based inflation subsystem. A feasibility assessment is made, based on a baseline configuration that uses a high-TRL propulsion system to remain at 90,000 ft altitude for 24 hours. The feasibility assessment is supported by analysis and by a subscale demonstration article. A development plan is created that addresses all technical challenges necessary for a full scale flight demonstration with wing deployment at 90,000 ft. altitude.
