  Finite Element Modeling of Active Twist in Rotor Blades using IDE-PFC Actuators

  By Partha Bhattacharya

  Abstract: Blade Vortex Interaction in rotating helicopter blades contributes significantly to the instability and high vibration levels during its operations. It is therefore essential to evolve a mechanism to reduce unwanted vibration. Several methods/devices, like the smart trailing edge flap actuators, active blade twist, etc are suggested. Active blade twist concept deals with changing the angle of attack and thereby reducing vibration and noise. The piezoelectric actuators are the promising devices …
