Abstract
A type of piezoceramic composite actuator commonly known as Macro-Fiber-Composite (MFC) is used for actuation in a novel, variable camber airfoil design. The study focuses on kinematical modeling, and theoretical static response characterization under aerodynamic loads. From a broader perspective, the study aims to understand the behavior of solid-state aerodynamic vectoring in high dynamic pressure air flow. The novel airfoil employs a single four-bar (box) mechanism as the internal structure. The MFC 8528 P1 type actuators are implemented in a bimorph configuration. The airfoil produces deflection in both directions from a flat camber line. The box mechanism amplifies the deflection and camber change as predicted. Increase in lift and drag performance is achieved when compared to thin, flat plate airfoil designs.
