<p>A trailing edge flap assembly for an aircraft wing includes at its rearward end upper and lower surfaces terminating in a trailing edge portion. The assembly has a flap (15) is located in a stowed position during normal flight. A mounting beam (18) is located to the lower surface (12) of the wing, extending rearwardly thereof and below the flap (15) A carriage (23) is in rolling engagement with longitudinal guideways (53) on the mounting beam (18). To actuate the flap (15), at or about the rearward extremity of the mounting beam (18), there is provided an actuator mounting bracket (21), a rotary actuator (52), and lever arms (27, 28) associated with the actuator about a common substantially transverse axis of rotation.The lever arms (27, 28) extend upwardly and terminate adjacent the undersurface of the flap (15), in a pivotal attachment (22) forwardly extending actuator links (25, 26) pivotally interconnecting the lever arms (27, 28) and the carriage (23). The flap (15) is supported by means of first link (33) interconnecting the carriage (23) to a forward portion of the flap (15), and a second link (36) interconnecting the actuator links (25, 26) to a more rearward portion of the flap (15). Location of a powered actuator (52) at the rear extremity of the mounting beam (18) in direct engagement with an actuating lever (27, 28) in close driving engagement with the flap (15) is both efficient and reduces power requirements.</p> |
