N2 - This work focuses on the design and testing of a piezoelectric actuator for a Miniature Trailingedge Effector (MiTE). MiTEs have the ability to increase performance of rotorcraft. A MiTE actuator is designed for a VR-12 rotorcraft airfoil with a chord of 0.356 m (14 in.). The requirements for this design include having a natural frequency of greater than 50 Hz to allow for quasi-static operation and a maximum deflection of 3.56 mm. Design of this actuator, a piezoelectric bimorph augmented by centrifugal loads, was done in conjunction with the design of a flap assembly. A tapered bimorph connected to a flexure hinge was the result of the design process. A full scale bench-top model was fabricated and tested and the design requirements were met.
