Abstract

A flap actuation mechanism incorporates a flap bracket attached to a flap and coupled to an underwing structure with a pivotal coupling. A crankshaft is configured for over center rotation and has aligned inboard and outboard crank arms extending from axially spaced inboard and outboard journals disposed in the underwing structure and configured to rotate about a rotation axis of the inboard and outboard journals. A crank pin is connected between the inboard and outboard crank arms. An actuating rod has a first end rotatably coupled to the crank pin and a second end coupled to the flap bracket. Rotation of the crankshaft displaces the actuating rod to cause rotation of the flap bracket and the flap.
