Abstract

Aircraft high-lift device (1) of a lifting surface (2) including an upper skin (3), lower skin (4) and a nose (5), the high-lift device (1) includes: a flexible skin allowing for a morphing high-lift device (1), having a rear upper edge (7.1) and a rear lower edge (7.2), at least the rear upper edge (7.1) sliding along the chordwise direction between a retracted position and an extended position, and a linear actuator (6) connected to the nose (5) and pivotably connected to the lifting surface (2) between the retracted position and the extended position, so that in the extended position the nose (5) is located in a downward location with respect to its location in the retracted position and at least the rear upper edge (7.1) is located in an anterior location with respect to its location in the retracted position.

Dependent claims

An aircraft high-lift device coupled to a lifting surface of an aircraft, the high-lift device has a chordwise direction and a spanwise direction, the high-lift device includes:

an upper skin including a flexible skin having a shape which morphs as the high-lift device moves between a retracted position and an extended position related to the lifting surface;
a lower skin including a flexible skin having a shape which morphs as the high-lift device moves between the retracted position and the extended position;
a nose forward of and attached to the upper skin and the lower skin,
a linear actuator between the upper skin and the lower skin, and connected to the nose, wherein the linear actuator is configured to be pivotably connected to the lifting surface and move the high-lift device between the retracted position and the extended position,
wherein the upper skin includes a rear upper section extending in the chordwise direction which is adjacent the lifting surface and is configured to slide along the lifting surface in the chordwise direction as the high-lift devices moves between the retracted position and the extended position,
wherein the lower skin includes a rear lower section extending in the chordwise direction which is adjacent the lifting surface and the rear lower section is configured to slide along the lifting surface in the chordwise direction as the high-lift devices moves between the retracted position and the extended position,
wherein, while the high-lift device is in the extended position, the nose is in a downward position relative to a position of the nose while the high-lift device is in the retracted position, and
wherein at least the rear upper section advances in the chordwise direction as the high-lift device moves from the retracted position to the extended position to increase lift generated by the lifting surface and the high-lift device.

5 more elements

A wing of an aircraft including:

a fixed wing including a first upper skin having a forward upper edge and a first lower skin with a forward lower edge, and
a high-lift device including:
a second upper skin including a flexible skin having a shape which morphs as the high-lift device moves between a retracted position and an extended position relative to the fixed wing;
a second lower skin which includes a flexible skin having a shape which morphs as the high-lift device moves between the retracted position and the extended position;
a nose forward of and attached to the second upper skin and the second lower skin of the high-lift device,
a linear actuator between the second upper skin and the second lower skin, and the linear actuator includes a first end region connected to the nose and a second end region pivotably connected to the fixed wing, wherein the linear actuator moves the high-lift device between the retracted position and the extended position,
wherein the first upper skin includes a rear upper section which is adjacent the lifting surface and is configured to slide along the lifting surface in the chordwise direction as the high-lift device moves between the retracted position and the extended position,
wherein the lower skin includes a rear lower section which is adjacent the lifting surface and is configured to slide along the lifting surface in the chordwise direction as the high-lift device moves between the retracted position and the extended position,
wherein, while the high-lift device is in the extended position, the nose is in a downward position relative to the lifting surface relative to a potion of the nose while the high-lift device is in the retracted position,
wherein the rear upper section and the rear lower section advance in the chordwise direction as the high-lift device moves from the retracted position to the extended position, and
wherein the rear upper edge is configured to slide in the chordwise direction against and remain in contact with the fixed wing as the high-lift device moves between the retracted position and the extended position.
