Extending wing flap for aircraft - has slot on trailing edge of flap for one or more extensions operated on flap pivoting

摘要

The trailing flaps for the aircraft wing have slots at the trailing edges so that extension flaps can be fitted. These are extended to increase the action of the flaps for landing etc. and to improve the performance of the aircraft. The flaps can be extended by cable drives, hydraulic rams, electric servos or by hinged support arms. They can be fitted to any design of aircraft and require simple controls to operate.
