摘要:
The invention relates to nose parts of the fairing of vertical and horizontal tails and wings of an aircraft with a skin and a support structure, the skin (2) being disposed on the support structure (4, 6). The support structure is provided with a plurality of ribs (6) and a plurality of stringers (4), the plurality of stringers being arranged on the plurality of ribs to support the skin. Advantageously, an improved deformation behavior can be obtained, e.g. in the event of an impact of a bird, while the weight and cost are minimized by providing the stringers.

Methods and apparatuses for installing and actuating movable components (140), including canards, over multiple ranges. An apparatus in accordance with one embodiment of the invention includes a canard (140) coupled to multiple actuators (161,665), one of which moves the canard over a first range of motion and the other of which moves the canard over a second, extended range of motion. A lockout device (690) can prevent actuation over the second range of motion except when selected conditions are met.

Efficient wing tip devices for use with aircraft wings. In one embodiment, an aircraft wing/winglet combination includes a wing having a wing root portion and a wing tip portion spaced apart from the wing root portion. The wing tip portion can have a wash-out twist relative to the wing root portion. The aircraft wing/winglet combination can further include a winglet extending from the wing tip portion of the wing. The winglet can be swept at least generally forward relative to the wing to favorably change the lift distribution on the wing and in turn reduce the induced drag on the wing.

Methods and apparatuses for rotatably supporting movable components (140), including canards. An apparatus in accordance with one embodiment of the invention includes an airfoil configured positioned external to an aircraft fuselage. A connecting portion (140) can depend from the airfoil portion and can have an attachment portion configured to attach to an aircraft, internal to the aircraft fuselage. Rollers (1080) carried by one of the connecting portion and the fuselage can rotatably contact a track (1070a) carried by the other of the connecting portion and the fuselage.

An aircraft includes a fuselage, a main wing pivotally coupled to an aft portion of the fuselage, and a canard coupled to a forward portion of fuselage, wherein the main wing and the canard are configured to be connected together for supersonic flight and disconnected from each other for subsonic flight.

The object of the invention is an aircraft provided with a device for creating a constant moment in relation to the axis of rotation of an additional control surface placed at the front of the aircraft at an as large as possible distance from the centre of gravity of the aircraft. The aircraft is characterised in that the control of the aerodynamic vertical force (7) is effected by deflecting control elements (3) pivotably mounted on the rotation axis (4), the deflection of said control elements causing rotation of a balance and control surface (1) mounted rotatably on axis (2), wherein the axis (2) is mounted perpendicularly to the plane of symmetry (5) of aircraft (6) forward of the resultant aerodynamic vertical force (7) generated by the balance and control surface (1).

A flight vehicle includes a fuselage 10 having a consumable fuel supply 18,12, main wings 12 each with an elevon 14 and a pair of jettisonable foreplanes 16. The foreplanes provide lift at take-off and during transonic flight and, at higher supersonic speeds they are jettisoned.
