Abstract
The presented work combines an innovative morphing actuation system and a new morphing structure to comprise a morphing airfoil with active trailing edge. The morphing actuation system has compliant rods driven by linear ultrasonic motors, which serve as actuator runners as well as structural elements that carry the load while naturally form smooth curvature under bending, and have the potential to become sensors and dataRlink. The morphing structure with compliant truss has shown satisfactory specific loading capacity in finite element simulation and static loading test, and allows morphing with multiple degrees of freedom. All degrees of freedom are fully controlled and could provide multiple morphing strategies, which, as proved by Xfoil analysis and wind tunnel tests, could benefit the aerodynamic efficiency at different flight conditions, and provide pitching moment control independent of lift.
