    摘要: 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.

    摘要: A rotor hub fairing system (36) for use in a counter-rotating, coaxial rotor system (12) is provided including an upper hub fairing (38) defined about an axis and a lower hub fairing (40) defined about the axis. A shaft fairing (42) is disposed between the upper hub fairing (38) and the lower hub fairing (40). The geometry of the shaft fairing (42) is configured to encourage a wake adjacent the upper hub fairing (38) to form collectively with a wake adjacent the lower hub fairing (40).

    摘要: A self-lubricated actuator for a rotor blade flap of a helicopter having a housing; a motor having a shaft disposed in a bearing is provided. The actuator further has an output rod and a mechanism operatively associated with the motor and the output rod to transmit movement from the motor to the output rod. The housing includes a lubrication medium capable of substantially immersing the bearing, the motor shaft and the mechanism during operation.
