摘要

An Active Camber Rotor (ACR) concept with integrated piezoceramic layers and continuous shape adaptation is proposed. Due to the interaction of the load carrying and shape adaptation capabilities, it is an aeroelastically unbalanced smart structure concept. Therefore, aeroservoelastic design and optimization is essential. For this purpose, a multiphysics simulation capability for the coupled piezo-aero-elasticity of smart helicopter rotor blades with integrated piezoelectric layers in transonic flow is developed. The numerical method is based on time-discontinuous Galerkin finite elements including Galerkin/least-squares stabilization and nonlinear higher order discontinuity capturing operators. We present numerical results of a design study for a smart tab actuated in bending. The aerodynamic effectiveness is investigated and the effect of the aeroservoelastic coupling is discussed.
