Method and apparatus for controlling a shape of a composite structure. A shape memory structure associated with the composite structure is activated. The shape memory structure changes from a buckled shape to an original shape and causes the composite structure to change from an undeployed shape to a deployed shape. The shape memory structure is deactivated. The shape memory structure changes from the original shape to the buckled shape in response to a load from the composite structure and causes the composite structure to change from the deployed shape to the undeployed shape.

L'invention concerne un aéronef à impact environnemental réduit comprenant deux turbopropulseurs (10) montés sur le dos de l'aéronef à l'arrière de celui-ci et un dispositif de masquage acoustique par turbopropulseur. Le dispositif de masquage acoustique comprend un élément de masquage (32) tel qu'un volet (33) pouvant se déplacer entre une position rétractée dans la voilure et une position déployée vers l'arrière de celle-ci. Dans cette position déployée, le volet (33) intercepte la zone de bruit (18) généré vers l'avant par le turbopropulseur de manière à réduire la perception au sol du bruit.
摘要:
An aircraft control system is presented. The system includes a wing including a flap track, and a shuttle connected to the flap track and configured to slide along a length of the flap track. The system includes a flap panel pivotally attached to the shuttle at a flap pivot. The flap panel is configured to rotate about the flap pivot. When the shuttle is deployed along a length of the flap track, the shuttle is configured to prevent rotation of the flap panel about the flap pivot, and when the shuttle is withdrawn into a stowed position, the shuttle is configured to allow the flap panel to rotate about the flap pivot.

The invention concerns a device for a adjustable flap adjustably mounted on a main wing surface of an aeroplane wing, in particular, a landing flap, with at least one adjustment unit for purposes of adjustment of the adjustable flap, which has an actuator arranged, or that can be arranged, on the main wing surface, and has a kinematic adjustment mechanism running between the actuator and the adjustable flap, wherein the adjustable flap is mechanically coupled with the actuator via the kinematic adjustment mechanism. In the device at least one damping unit for purposes of damping a dynamic loading effected by the adjustable flap on the adjustment unit, which in particular can be brought about as a result of a critical malfunction event occurring in the region of the adjustable flap, is arranged, or can be arranged, between the main wing surface and the adjustable flap.

The invention relates to an aerodynamic body which can be adjusted relative to a main wing of an aircraft by means of an adjusting device, a variable gap (G) being produced on a lateral end (E1, E2) due to the adjustment of the same between the aerodynamic body and a second aerodynamic body or a component of a fuselage or of the main wing. Said aerodynamic body comprises a gap bridging device (1) having a shell part (20) that extends along the gap (G) and that overlaps the outer shell of the aerodynamic body in the span width direction (SW1, SW2) on the front face thereof in such a manner that the shell part (20) can be telescoped relative to the aerodynamic body in the span width direction (SW1, SW2). The invention also relates to a wing for an aircraft comprising a main wing and a plurality of juxtaposed aerodynamic bodies (A1, A2) which are arranged at a right angle to the direction of the chord of wing (S1). The invention further relates to a wing for an aircraft comprising a main wing and an aerodynamic body (A1, A2) which can be adjusted relative to said main wing by means of an adjusting device and which is arranged next to a component of the fuselage or of the main wing at a right angle to the direction of the chord of wing (S1), and to an aircraft comprising said wing.
