摘要:
A pivoting panel for an aircraft and to a composite support piece for this kind panel. The support piece (17) is arranged as a part of the frame structure of the panel (3). The support piece has an extension portion (23) to which an actuator connection fitting (7) of an actuator (4) can be fastened. The extension portion (23) distributes the forces to the structures of the panel (3).

An aircraft comprises first and second wings positioned on opposite sides of a longitudinal axis with each of the first and second wings including an upper surface and a lower surface, wherein no control surfaces are attached to the lower surface of the wings. A first forward opening control surface is attached by a first hinge to an upper surface of the first wing and a second forward opening control surface being attached by a second hinge to an upper surface of the second wing. Each of the first and second hinges is canted with respect to a direction perpendicular to the longitudinal axis. A method of yaw control performed by the aircraft is also included.

A supersonic aircraft comprises a fuselage extending forward and aft, wings coupled to lateral sides of the fuselage, and canards coupled to lateral sides of the fuselage forward of the wings. The individual canards are configured to generate shocks that wrap around the fuselage and intersect with wing leading edges on opposing sides of the fuselage.

Systems and methods for controlling aircraft flaps and spoilers are disclosed. Systems in accordance with some embodiments include a wing having a trailing edge, and a flap positioned proximate to the wing trailing edge and being deployable relative to the wing between a first flap position and a second flap position by operation of a first actuator. A spoiler can be positioned at least proximate to the trailing edge and can be movable among at least three positions, including a first spoiler position in which the spoiler forms a generally continuous contour with an upper surface of the wing, a second spoiler position deflected downwardly from the first, and a third spoiler position deflected upwardly from the first. A second actuator can be operatively coupled to the spoiler to move the spoiler among the first, second and third spoiler positions in a manner that is mechanically independent of the motion of the flap.

An aerodynamic including a main body and a control member. The main body is configured to be connected to a wing of an aircraft. The control member is connected to the main body, the control member including a fixed member secured to the main body and a pivotable member configured to increase a drag of the aircraft without substantially changing a lift of the aircraft.
摘要:
Method and spoiler system for ensuring the aerodynamic continuity of the upper surface of an aircraft wing.According to the invention, the spoiler 7 has a chord (C) of adjustable length and means (16, 19, 20) are provided for acting on the length of said chord when said spoiler (7) is in the retracted position.

A supersonic aircraft comprises the fuselage extending forward and aft along a longitudinal axis, a wing coupled to the fuselage, and a canard. The canard is coupled onto the fuselage forward of the wing at an elevated position that enables stretching of the aircraft lifting length and forms an effective area distribution to attain a shaped sonic boom signature.
摘要:
An aircraft with swept back wings and spoilers inlaid into the top surface near the tips of the wings. The aircraft also includes an elevator formed in the center back portion of the aircraft, which is also aft of the spoilers. It is aft to allow an auxiliary control in the elevator signal to cancel the unwanted pitch up moment caused by the spoilers only going up and being aft of the center of gravity of the aircraft. Roll is achieved with these spoilers by the direct action of the lift dumping on one side or the other and by taking advantage of the transformation of yaw into roll by the sweep back of the wings.

摘要:
A method and apparatus is provided for countering asymmetrical aerodynamic forces subjected onto an aircraft. Asymmetrical forces are counteracted by this invention automatically by selectively actuating force inducing elements in response detection of one of (a) differential longitudinal forces induced upon the aircraft by the engines and (b) undesirable rotation of the aircraft about longitudinal axis "c" of the aircraft. The force inducing elements of this invention function independent of primary control elements and other control surfaces of the aircraft.
