Abstract
This paper examines the application of a relatively new type of piezoelectric actuator, termed a Macro Fiber Composite, on small unmanned air vehicles with a wingspan of 0.61 m for the purpose of active flight control. The design is examined on a local–global level with the primary goals being to maximize curvature and load bearing capacity of the actuator-substrate component while also maximizing the effective roll and pitch moment when the actuator component is applied on the aircraft. Within this document the strain of the individual MFC is measured, the performance of various substrates and adhesives examined within a cantilever setup and a four point bend setup, and the overall performance of the MFC actuators evaluated when embedded on an innovative forward swept Micro Air Vehicle wing. The wing incorporates composite material bend-twist coupling to allow passive load alleviation while providing a planform for sufficient control authority using only two MFC actuators.
