Abstract:

The primary objective of the proposed program is to develop and design a distributed actuation methodology for wing warping in UCAVs aimed at 1 control of higher-order flutter modes, 2 increased maneuverability, and 3 reduced radar signature. Specific milestones achieved during the funded phase of the program include 1 Completed design and testing of high aspect ratio wing model in Duke University Wind Tunnel to correlate computer model used to design wing - LCOFlutter. 2 Completed design and bench testing of V-Stack actuator for integration into airfoil. 3 Completed design specifications for a typical section wind tunnel model to evaluate performance of V-stack actuator with a single control surface. 4 Performed initial design of continuously deformable control surface and evaluated performance for flutter suppression. 5 Developed reduced-order models to evaluate enhanced roll performance of a warped, adaptive, aeroelastic wing.
