| Abstract |
Technologies are being investigated that will enable the production and use of high altitude, long endurance (HALE) aircraft. Requirements for this application include a light weight and low storage volume to allow easier delivery of the vehicle to such altitudes. Ultraviolet (UV) light rigidizable inflatable wings offer a means of achieving the high packing efficiency required as well as offering the capability of higher L/D that is required for HALE applications. Rigidization of inflatable wings is the key, providing several potential advantages, including reduced vulnerability to punctures, increasing stiffness and load-carrying capability, allowing a higher aspect ratio for high altitude efficiency and longer missions, and reducing weight by eliminating the make up pressurization supply. |
