Abstract

Smart material actuator technology for operation `on the blade' is now becoming available and has the promise to overcome the size, weight and complexity issues of hydraulic and electric on-rotor actuation. However, the challenges of the limited output capability of the materials and the dynamic operating environment must be fully addressed and resolved. The present study covers the conceptual sizing and design of a full scale demonstration system to provide active control of noise and vibrations as well as inflight blade tracking for the MD-900 helicopter. Active control is achieved via a trailing edge flap and trim tab, both driven by on- blade smart material actuators. Overall, this ARPA sponsored program entails the design, development, and whirl tower testing of the full scale active control rotor system. If successful, an entry in the NASA Ames 40 X 80 foot wind tunnel and flight tests are planned for a follow on program.
