Abstract
A trailing edge flap mechanism for an aircraft incorporates a flap actuator 28 and a fore flap link 30 that pivots by actuation of the flap actuator. The fore flap link has a hinged end 32 pivotally coupled to a fore flap structure 34 and a clevis end 36 pivotally coupled to a fixed wing structure 18 at a first hinge axle 38. A rocking lever 40 is pivotally coupled to a second hinge axle 42 on the fixed wing structure. A connector bar 44 has a first end 46 pivotally coupled to the fore flap link at a first connection axle 48 and a second end 50 pivotally coupled to the rocking lever at a second connection axle 52. Pivotal movement of the fore flap link causes movement of the connector bar that is translated into rotational movement of the rocking lever about second hinge axle 42 to move an aft flap link 54 pivotally coupled to an aft flap structure 56 at a first pivot axle 58 and pivotally coupled to the rocking lever at a second pivot axle 60, thereby deploying the flap to a lowered position relative to a trailing edge portion of the wing.
