Flap Configuration and Control Law,aerodynamic model used in that chapter did not include the unsteady effects due to the motion of trailing-edge flaps. Also, the effects of the rotor wake were captured using a simple linear inflow model. In this chapter, a two-dimensional unsteady aerodynamic model for a flapped airfoil in compressi

Consequence

Piezoceramic Actuator Hysteresis,material and mechanical hysteresis in the piezoelectric actuator is modeled using the classical Preisach model. Experimental data from literature is used to estimate the Preisach distribution function.

Active Rotating Beams,oser approximation to rotating beams due to their high aspect ratios. However, the structural dynamic and aerodynamic behavior are highly coupled for helicopter rotor blades. To obtain an idea about the physics behind the active twist concept and to validate the formulation and analysis developed in

Box-Beam Active Rotor Blades, more on the development and validation of the concept of induced-shear-based piezoceramic actuation in helicopter rotor blades considering a simple two-cell box cross section. It is known that two-cell cross-section model is closer approximation to a realistic rotor blade section and is a good mode
