Publication number: 20110031348Abstract: An aircraft landing gear comprising: an arm mounted to a pivot and carrying one or more wheel assemblies; and a composite leaf spring which is coupled to the arm and arranged to provide a resilient biasing force which opposes rotation of the arm about the pivot. The arm can be made relatively stiff in comparison with the leaf spring, so that load is transferred directly into the pivot without a large amount of bending of the leg. The leaf spring shock absorber typically has a reduced part count compared with a conventional oleo-pneumatic shock absorber. By forming the leaf spring from a composite material, its weight is significantly reduced in comparison with a conventional metal spring, making it suitable for use on a relatively large aircraft.Type: ApplicationFiled: February 24, 2009Publication date: February 10, 2011Applicant: AIRBUS UK LIMITEDInventor: Robert Ian Thompson

Publication number: 20100301172Abstract: An aerodynamic structure (1) comprising a series of shock bumps (3a, 3b, 3c) extending from its surface. The shock bumps are distributed along a line (7) with a smaller mean angle of sweep than an unperturbed shock (4) which would form adjacent to the surface during transonic movement of the structure in the absence of the shock bumps. Instead of being distributed along the line of the unperturbed shock, the shock bumps are distributed along a line which is less swept than the mean angle of sweep of the unperturbed shock. When the structure is moved at a transonic speed; a shock forms adjacent to its surface and the shock bumps perturb the shock (9) so as to reduce its angle of sweep.Type: ApplicationFiled: February 17, 2009Publication date: December 2, 2010Applicant: AIRBUS UK LIMITEDInventor: Norman Wood

The hinge assembly includes a spar bracket attached to a rear spar in the main structure element, and a control device bracket attached to control device spar. The hinge assembly is pivotally coupled to the spar bracket about a hinge line, about which the actuator rotates the control device. The actuator is pivotally coupled to the main element at a first pivot point and to the control device at a second pivot point, the length of the actuator between the pivot points being adjustable for rotation of the control device. The hinge line is positioned closer to the rear spar than to the control device spar.

Patent number: 7813830Abstract: A drilling machine drills at a multiplicity of target locations on a component. Two robots, calibrated with calibration data, move the component in a 6-D coordinate system. A metrology system ascertains the position of the component relative to the drilling machine. The movement of the robots is effected by commands generated by off-line programming. The component is moved relative to the drilling machine to a target position, ready for drilling, by a closed-loop process in which the differences in position between the expected position (the target position) and the actual position (as viewed by the metrology system) are corrected.Type: GrantFiled: January 26, 2006Date of Patent: October 12, 2010Assignee: Airbus UK LimitedInventors: Mark Derren Summers, Roger Holden, Brett Jason Green

Patent number: 7802753Abstract: Unsafe electric energies can exist in aircraft fuel tanks as a result of static build-up or induced currents from lightning strikes. The invention provides an aircraft having a ground circuit 19 and including a fuel tank having a fuel probe circuit having its own ground circuit. Multiple discharge paths allow the safe discharge of electricity from the tank before it reaches levels where an arc, spark or other electric discharge, able to ignite fuel in the tank, could occur. The discharge paths all pass via a conductive foam having a relatively high impedance that allow static bleed, but does not significantly increase the risk of currents induced by lightning reaching levels at which an ignition-causing electrical discharge might occur. The foam is securely bonded to both the aircraft ground circuit and the fuel probe ground, the bonds having a large area of surface-to-surface contact.Type: GrantFiled: August 2, 2005Date of Patent: September 28, 2010Assignee: Airbus UK LimitedInventors: Franklin George Tichborne, Kim Michael Ley
