In this paper the use of Terfenol-D magnetostrictive rods for actuation of an intelligent rotor is being addressed. The challenge in the use of these actuators in intelligent rotor applications is housing them in the structure of the rotor. The packaging of the Terfenol rod actuators, considered in this work, inside the structure of the rotor blade is based on lining the actuators in the center of the spar along the axis of the blade. This is possible due to the fact that most blades have a hollow D or box spar. The two ends of each actuator is sandwiched between two plates which, for flapwise actuation of the spar, are attached to the top and bottom of the spar, alternatively. This arrangement translate the actuator force to a point moment on the blade, at the actuator location.
