Abstract
The leading edge (12) of an aircraft wing is equipped with a kruger nose which includes a rigid flap (18) and a mechanism (26,28,30,40) ensuring the deployment of the flap in an intermediate landing position (P3) and in a take-off position (P2). The disposition of this mechanism is such that, in the landing position (P3), a slot exists between the flap (18) and the leading edge, whereas this slot disappears in the take-off position (P2). The mechanism preferably includes two connection rods (28,30) connecting a control reversing lever (26) and an intermediate reversing lever (40).
Claims13
A Kruger nose for deployment over the leading edge of an aircraft wing comprising a rigid flap, a control member housed in the leading edge of the aircraft wing with said rigid flap being responsive to the position of the control member for assuming at least three different positions including a retracted flight position in which the flap forms an intrados region of the leading edge, at least one intermediate position in which a slot is formed between the flap and the leading edge, and a deployed take-off position in which there is no slot between the flap and the leading edge and a movement control mechanism interconnecting the flap and said control member so as to move the flap into anyone of said different positions.
A Kruger nose for deployment over the leading edge of an aircraft wing comprising a rigid flap, a control member housed in the leading edge of the aircraft wing below the median plane thereof with said rigid flap being responsive to the position of the control member for assuming at least three different positions including a retracted flight position in which the flap forms an intrados region of the leading edge, at least one intermediate position in which a slot is formed between the flap and the leading edge, and a deployed take-off position in which there is no slot between the flap and the leading edge and a movement control mechanism interconnecting the flap and said control member so as to move the flap into anyone of said different positions.
