A high-lift device (3) comprises a flap body (11) which is provided at a rear portion of a main wing (2) which generates a lift for the air vehicle such that the flap body is deployed with respect to the main wing and stowed in the main wing and extends along a wingspan direction of the main wing (2); and a gap increasing section (20, 30) provided at an end portion (11a) of the flap body (11) in an extending direction of the flap body, to increase a gap between the rear portion of the main wing (2) and a front portion of the flap body (11) in a state in which the flap body is deployed.

A flap system (2) for an aircraft comprises a flow body (4, 36), a trailing flap (6) and a movement means (18, 20). The flow body (4, 36) comprises an upper surface (13) and a lower surface (15), the lower surface (15) having a recess (28). The movement means (18, 20) is attachable to the flow body (4, 36) and the trailing flap (6). The trailing flap (6) comprises a shape that corresponds to the recess (28) in the lower surface (15). The movement means (18, 20) is adapted for conducting at least a chordwise movement of the trailing flap (6) such that it is movable out of and into the recess (28) of the flow body (4, 36) in absence of a gap between the leading edge of the trailing flap (6) and the flow body (4, 36). Thereby, a clear increase in a lift coefficient may be achieved, while at the same time maintaining a low complexity and a high reliability of the flap system.

An aircraft (10) comprises trailing edge flaps (17), a wing mounted propulsor (26) positioned such that the flaps (17) are located in a slipstream of the first propulsor in use when deployed. The aircraft (10) further comprises a thrust vectorable propulsor configured to selectively vary the exhaust efflux vector of the propulsor in at least one plane. The thrust vectorable propulsor comprises a ducted fan (30) configurable between a first mode, in which the fan (30) provides net forward thrust to the aircraft (10), and a second mode in which the fan (30) provides net drag to the aircraft. (10). The fan (30) is positioned to ingest a boundary layer airflow in use when operating in the first mode.

An airfoil may include a leading edge 200 and a shape control mechanism 400. The leading edge may include a flexible leading edge skin 214 having a first end 216, a second end 218, and an arc length defined therebetween. The shape control mechanism may be attached to the flexible leading edge skin at a plurality of support locations 224 and may transition the flexible leading edge skin from a first shape 228 having a first curvature profile 230 to a second shape 232 having a second curvature profile 234 different than the first curvature profile without a change in the arc length.
摘要:
The present invention provides a high lift system for an aircraft, which extends and retracts the landing flaps of the aircraft in a fully electric manner. In this context, a fully electric drive is used, comprising an electric motor having an internal redundancy, in such a way that the electric motor is configured as a fault-tolerant electric motor. It may thus be possible to do without a coupling gear unit in the electric motor.
摘要:
In a high-lift-device, a wing, and noise reduction device for a high-lift-device that are capable of reducing noise generated when a flap is extended, preventing deterioration of aerodynamics characteristic when retracting the flap, and preventing an increase in weight, a flap main body (5) disposed so as to be extendable/retractable relative to a main wing and a protruding portion (6A-1) that smoothly protrudes at least at the vicinity of one end portion of a positive-pressure surface (PS) of the flap main body (5) in a direction away from the flap main body (5) are provided.
