Actuation system for an active element in a rotor blade

摘要

In accordance with one embodiment of the present application, an actuation system (115) is configured for actuation of an airfoil member (113) with a flap mechanism (117). The actuation system can include an upper drive tape (125) and a lower drive tape (127), each partially wrapped around a first bearing (129) and second bearing (131). An inboard frame (119) can be actuated by at least one linear actuator. Similarly, an outboard frame can be actuated by at least one linear actuator (123a, 123b). The inboard frame is coupled to the upper drive tape, while the outboard frame is coupled to the lower drive tape. Actuation of the inboard frame (119) and outboard frame (121) in a reciprocal manner acts to move a flap input lever reciprocally upward and downward. A flap mechanism is configured to convert the movement of the flap input lever (133) into rotational movements of the airfoil member (113).
