A landing gear for an aircraft includes a shock absorber strut ( 1 ) with upper and lower telescoping portions ( 2, 3 ), the upper portion ( 2 ) being connectable to the airframe of the aircraft. An arm ( 4 ) extends fore and aft relative to the aircraft and carrying a landing wheel, ( 7, 7 1 ), and pivotally connects by a main pivot ( 5 ) to the lower portion ( 3 ) of the shock absorber strut. A load reacting unit ( 9 ) connects between the arm ( 4 ) and the shock absorber strut ( 1 ) for reacting to load applied between the arm and shock absorber strut on landing. An indicator ( 60 ) monitors the load applied to the load reacting unit ( 9 ) on landing. The load reacting unit ( 9 ) may be connected between a forward end of the arm ( 4 ) and the upper portion ( 2 ) of the shock absorber strut to make the gear act as a semi-levered landing gear. Alternatively, the load reacting unit ( 9 ) may be connected between the arm ( 4 ) and the lower portion ( 3 ) of the shock absorber strut to act as a pitch trimmer. The arm ( 4 ) may include a bogie beam with fore and aft landing wheels ( 7, 7 1 ) with the main pivot ( 5 ) therebetween. The load reacting unit ( 9 ) preferably has a fluid pressure unit and the indicator ( 60 ) includes a mechanical indicator that operates at a predetermined pressure threshold.

Load detection in an aircraft landing gear

A steerable and retractable aircraft nose landing gear assembly including a cross link for rapidly connecting and disconnecting the nose wheels from the aircraft steering mechanism and a common locking arrangement for locking the wheels in retracted or extended positions is disclosed. The cross link arrangement connects a movable collar attached to the steering mechanism to a collar affixed to the wheels when the wheels are to be steered by the steering mechanism. Opening of the cross link separates the wheels from the steering mechanism and, thus, allows the aircraft to be freely moved by a towing vehicle without feedback to the steering mechanism occurring. The common locking mechanism comprises a bungee spring operated pair of off-center locking links running between the drag strut linkage and a flange affixed to the aircraft. The operation of an actuator rotates the links against the force created by the bungee spring to unlock the mechanism. When in either the extended or the retracted position, the off-center locking links prevent movement of the drag strut linkage in a manner such that the wheels are prevented from moving to the opposite position.

Steerable and retractable aircraft nose landing gear assembly

An aircraft landing gear includes an axle on which wheel and brake assemblies are mounted. An adaptor member is mounted on the axle and arranged to define a brake rod connection point that is distinct from a conventional brake rod connection point defined by the brake assembly. The adaptor member is coupled to the brake assembly via an adaptor linkage that is arranged to react brake torque but arranged to permit relative movement between the adaptor member and the brake assembly in degrees of freedom which are not required to react brake torque.

Aircraft landing gear assembly

A reduced-volume casing for a landing gear including a chassis for fixing and taking up loads, to which the landing gear is exposed and an envelope-type structure arranged on the chassis for taking up pressurization forces. The chassis can include, in particular, a frame which is even to the output opening of the landing gear and is provided with beams used for receiving means for maintaining the fastening bearings of the gear and also including polygons which are used for receiving the fastening bearings of the gear manoeuvring strut and are fixed to the beams, wherein the beams and polygons form a lattice structure.
