Title:
MOVABLE BLADE
Document Type and Number:
Japanese Patent JPS62173398
Kind Code:
A
Abstract:
An aircraft wing with a trailing edge flap and a flap-supporting system toward each end of the flap. The flap-supporting systems are completely housed within the wing of the aircraft when the flap is in its stowed or retracted position. Each of the flap-supporting systems includes a first track (54) to which the flap is attached. That track is displaceable in a chordwise direction between extended and retracted positions. Also included in each flap-supporting system is a second, immobile program track (44) and a crank-and-follower (96) system which cooperates with that track to change the angle of the flap as the flap is extended. Lead screw type drives are employed to extend and retract the flap, and cans are used to keep fuel from leaking out of the wing through openings provided in the latter's rear spar to accommodate the first-mentioned tracks of the flap-supporting mechanismus.
