Abstract:
Apparatus for improving flow characteristics around aircraft wings by obstructing air flow through an aperture formed in a wing skin for a movable duct or track are disclosed. In one embodiment, the apparatus comprises a substantially rigid panel movable at least partially across the aperture for at least partially occluding the aperture and for accommodating movement of a slat track extending through the aperture. In another embodiment, the apparatus comprises a hinged panel configured to swing outwardly from an outer side of the wing skin toward an open position to accommodate movement of an anti-icing duct extending through the aperture and to swing toward a closed position at least partially occluding the aperture.
Abstract:
A support unit for a structure within a pressure vessel that includes an external load distribution plate, an internal load distribution plate, a standoff unit between the external load distribution plate and the internal load distribution plate that extends through an opening in a pressure vessel.
Abstract:
A flap roller arrangement for supporting a flap on a wing of an aircraft is disclosed herein. The flap roller arrangement includes, but is not limited to, a roller assembly that is configured for rolling engagement with a flap track of the wing and for engagement with a flap fitting. The flap roller arrangement further includes a retaining member that is removably coupled to the roller assembly. The roller assembly is configured to egress through an opening in the flap fitting in a direction away from the flap track. The retaining member is configured to obstruct egress of the roller assembly through the opening when the retaining member is coupled to the roller assembly. The roller assembly is enabled to egress through the opening when the retaining member is removed from the roller assembly.
Abstract:
The invention relates to an auxiliary flap arrangement for modifying the profile of an aerodynamic body, in particular the trailing edge of the aerodynamic body. The auxiliary flap arrangement here exhibits at least two auxiliary flaps (20, 40) that can be adjusted by means of an adjustment device (60) while coupled to each other.
Abstract:
System and method for minimising buffeting in the case of an aircraft (2), wherein buffeting load control elements (10) which are provided in aerofoils of the aircraft (2) can be at least partly moved out of the aerofoils by a control means (1) to reduce buffeting loads acting on the aircraft (2).
Abstract:
A method of providing conditional electrical isolation for a bearing is disclosed. An inner race coupled to a first structure and an outer race coupled to a second structure are provided. An isolative means is provided for conditionally electrically isolating the first structure from the second structure.
Abstract:
El sistema incorpora medios (16) de transmisión de deflexión para proporcionar una posición de deflexión de un dispositivo (8) hipersustentador móvil, instalado en el HTP (2) móvil de una aeronave (1), para cada posición del ángulo de calado del HTP (2). Preferiblemente, los medios (16) de transmisión de deflexión (18, 20, 23) consisten esencialmente en una ligadura mecánica conectada entre el dispositivo (8) hipersustentador y la aeronave (1).
Abstract:
An actuation system configured to deploy a high-lift device on a leading edge of an aircraft wing. The system comprises: a link pivotally connected to the wing at a first pivot point and to the high-lift device at a second pivot point; a first actuation mechanism configured to rotate the high-lift device about the first pivot point; and a second actuation mechanism configured to rotate the high-lift device about the second pivot point. The second actuation mechanism is operable independently of the first actuation mechanism, and can be operated in order to generate a sealing force between the high-lift device and the leading edge of the aircraft wing.
Abstract:
In one embodiment, an apparatus is provided for covering and uncovering a flap opening in an aircraft. The apparatus comprises a door member, a torque tube roller member, at least one roller member, and a biasing member. The door member may be adapted to cover and uncover a flap opening. The torque tube roller member may be attached with the door member, and may be adapted to be pushed by a torque tube member attached with a flap of an aircraft. The door member may be adapted to be driven from a closed position covering a flap opening into an open position uncovering a flap opening. The roller member may be attached with the door member and may be adapted to follow at least one track member. The biasing member may be attached with the door member for biasing the door member towards a closed position covering a flap opening.
Abstract:
An aircraft can include a wing (42) with a leading edge (64) and a trailing edge (66). The wing has a main body (74) and movable control surfaces (80, 82) coupled to the main body. The wing (42) generates lifting forces when the aircraft is in flight. The movable control surfaces can be used to control the generated lifting forces. A spanwise flow inhibitor (70) extends from the outer wingtip (96) of the wing. At least one gurney flap (100, 102) extends generally downwardly from at least a portion of the trailing edge (66) of the wing. The flap at least partially counteracts a change in center of lift attributable to the spanwise flow inhibitor.
