A panel assembly for an aircraft comprises a panel rotatably connected to a support structure and moveable between a first position and a second position. The panel has an aerodynamic surface with a slot at one edge thereof which receives a portion of the support structure when the panel is in the first position. The assembly further comprises a resilient seal member which occupies the slot when the panel is in the second position. The panel may be an aircraft flight control surface, or an aircraft landing gear bay door.

An aircraft wing comprising first and second fuel pipe segments which are coupled together with a pipe coupling device comprising a corrugated tube formed from an elastomer filled with conductive material. The pipe coupling device is particularly useful for connecting together fuel pipe segments in an aircraft wing as it removes the need to attach bonding leads between fuel pipe segments to dissipate lightning currents and static.

A method and apparatus is disclosed for joining of composites with thermoplastic surfaces. The process includes the location of the said components within a load bearing frame, and bringing the thermoplastic surfaces to be joined into contact. Pressure application devices, in the form of fluid filled bladders, are also located within the frame, and are located such that pressure is applied evenly to said thermoplastic surfaces. Where components have a high level of curve or twist, form blocks that have the approximate shape of the component surface are located between the frame and bladders. Pressure and heat are applied to the joint area, and heat removed while the joint area is maintained under some pressure. A feature of the present invention is the option of using opposing pressure application devices, reducing the need for substantial tooling in order to maintain component location accuracy. A distinct advantage of this invention is the flexibility to join curved or twisted components, or complete the welding of closed assemblies such as wing boxes.

Process for manufacturing an assembly made of a composite material and wing and stabilizing element obtained by this process.The junction zone for a part (P) made of a composite material comprising two parts (A1, A2) in which the principal directions intersect at a non-singular angle, is made in a single operation by continuous lay-up. The 0° directions of the lay-up coordinate systems (R1, R2) of the parts (A1, A2) are oriented such that these directions make an angle of close to 180°−θ°, where ±θ° represents the other directions of the lay-up coordinate systems (R1, R2). Thus, the layers of fibers oriented at 0° in one of the coordinate systems correspond approximately to a lay-up direction of ±θ° in the other coordinate system.

A method of forming an internal structure within a hollow component (2), the component comprising first and second panels (4, 6) and at least one membrane (8; 10) disposed between the first and second panels (4, 6), the method comprising: selectively bonding the at least one membrane (8; 10) to the first and/or second panels (4, 6); inflating the component (2) by passing a pressurised fluid between the first and second panels (4, 6) such that the first and second panels (4, 6) are inflated into contact with a die assembly (38) and such that the membrane (8; 10) forms an internal structure between the first and second panels (4, 6); and deforming the internal structure by applying the pressurised fluid at a first pressure (P1) on one side of the membrane (8; 10) and at a second pressure (P2) on the other side of the membrane (8; 10).
摘要:
A panel assembly for an aircraft including a panel having an upper aerodynamic surface and a leading edge, and a hinge fitting connected to an underside of the panel, defining a hinge line for the direction of rotation of the panel. The upper surface of the leading edge has an arcuate portion centered about the hinge line, and has an upturned portion forward of the arcuate portion. The panel assembly is pivotally connected to its hinge fitting to the trailing edge of the fixed wing portion and rotatable between a first position wherein the upper surfaces of the fixed wing portion and the panel are substantially flush, and a second position wherein the panel is rotated downwardly from the first position. A seal member attached to the trailing edge of the fixed wing portion, has a lower surface which seals against the upper surface of the panel during its movement.

A system for power generation comprises a wing, a turbine, a tether, and a tether tension sensor. The wing is for generating lift. The turbine is coupled to the wing and is used for generating power from rotation of a propeller or for generating thrust using the propeller. One end of the tether is coupled to the wing. The tether tension sensor is for determining a tension of the tether.
