Actuation system for leading edge high-lift device

摘要

An actuation system configured to deploy a high-lift device on a leading edge of an aircraft wing. The system comprises: a link pivotally connected to the wing at a first pivot point and to the high-lift device at a second pivot point; a first actuation mechanism configured to rotate the high-lift device about the first pivot point; and a second actuation mechanism configured to rotate the high-lift device about the second pivot point. The second actuation mechanism is operable independently of the first actuation mechanism, and can be operated in order to generate a sealing force between the high-lift device and the leading edge of the aircraft wing.

1. An actuation system configured to deploy a high-lift device on a leading edge of an aircraft wing, the system comprising:
a. a link pivotally connected to the wing at a first pivot point and to the high-lift device at a second pivot point; b. a first actuation mechanism configured to rotate the high-lift device about the first pivot point in order to move the high-lift device downward around the leading edge from a stowage position to an intermediate position; and c. a second actuation mechanism configured to rotate the high-lift device about the second pivot point, wherein the second actuation mechanism is configured to operate independently of said first actuation mechanism when the high-lift device is in both the stowage position and the intermediate position, to generate a sealing force between the high-lift device and the leading edge of the aircraft wing, and is configured to release said sealing force to move the high-lift device from the intermediate position to a fully extended position, said fully extended position including a slot between said high-lift device and said leading edge of said wing.
