Aeroelastic Leveraging and Control through Adaptive Structures
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 - LCO/Flutter. (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.
