Abstract
A helicopter rotor blade having a blade body that defines a confined space and a control flap that is secured to the blade body that moves through a range of motion. An electric machine is secured inside of the rotor blade body that rotates a motor shaft. A transmission device is secured to the motor shaft and the control flap that transfers rotary motion of the motor shaft to the control flap to generate movement of the control flap through its range of motion. The transmission device remains substantially within the confined space throughout the range of motion.
