Abstract
An airfoil, a flap mechanism and an associated method are provided to controllably actuate a flap positioned proximate the trailing edge of an airfoil body. The flap mechanism includes a carrier beam hingedly connected to an airfoil body and also pivotally connected to a flap proximate the trailing edge of the airfoil body. The flap mechanism further includes an actuator, a first plurality of links and a second plurality of links. The first plurality of links is operably connected to the airfoil body, the actuator and the carrier beam. The first plurality of links causes the carrier beam to be rotated with respect to the airfoil body in response to actuation by the actuator. The second plurality of links is responsive to rotation of the carrier beam with respect to the airfoil body. The second plurality of links causes the flap to be rotated with respect to the carrier beam.
