The present study covers the analysis of a bearingless rotor with trailing edge flaps for active control of rotor aerodynamics and dynamics. The flaps are actuated by piezoelectric actuators installed in the blade. Two aeroelastic codes are used to explore the aerodynamics and dynamics of this rotor. CAMRAD/JA is based on the mode shape approach and has been modified to account for the flap aerodynamics. CAMRAD II is based on the finite element method and allows for complete aeroelastic modeling of the flap. Results show that the simple but efficient code may be used to predict rotor response and conduct concept development and active control law development. The advanced code must be used to obtain more accurate loads and to study the coupled blade/flap dynamics and stability.
