Paper Abstract

Three methods of decoupling and one method of increasing actuator strain throughenhanced directional attachment (EDA) are presented. Directionally attached piezoelectric(DAP) elements are laminated to an uncoupled plate to generate 44°/m in bending without twistand 31°/m of twist without bending. The strains are enhanced 5 to 12% when the elements aretransversely stiffened. Analytical EDAP models are presented with experiment and theory inclose agreement. A comparison of EDA to current laminating techniques demonstrates 50 to 1000%higher strain rates in twist. Data from a wing using EDAP elements is also briefly summarized.
