    摘要: An actuator (2) comprises first and second linear motion devices, each able to extend the actuator (2) and arranged such that jamming of one of the first or second linear motion devices does not preclude operation of the other. The first linear motion device comprises a first linear screw (10), a first nut (12), and a first prime mover (14) arranged to impart relative linear motion between the screw and nut. Similarly, the second linear motion device comprises a second linear screw (20), a second nut (22), and a second prime mover (24) arranged to impart relative linear motion between the second screw and nut. The first linear screw (10) may have a bore (18) in which the second linear screw (20) is accommodated when the actuator (2) is in the retracted position.

    摘要: The invention refers to a method for operating a landing gear system, preferably in a tricycle configuration, wherein main landing gear (MLG) and the nose landing gear (NLG) are operable from a retracted position where they are housed respectively inside landing gear bays, to a fully extended position where they are extended for landing the aircraft. According to the invention, the extension of the nose landing gear (NLG) is delayed in time with respect to the extension of the main landing gear (MLG), and the nose landing gear (NLG) is kept retracted during a major part of the time that the main landing gear doors (MLGD) are extended. In this manner, vibrations on the main landing gear doors are reduced and incidents caused by fatigue are also reduced, with in turn implies that the maintenance cost of the aircraft is greatly reduced.

    摘要: Landing gear doors may be opened in an emergency event, e.g., a failure of the normal landing gear actuation system that requires a gravity free-fall deployment. The retractable aircraft landing gear door actuation mechanism will include a landing gear door (12-1) and a door support bracket (22) attached to the landing gear door. The support bracket (22) is attached to aircraft structure (10-1) for pivotal movement about a pivot axis (22-1a) between a closed condition whereby the landing gear door covers an aircraft landing gear when retracted relative to the aircraft structure, and an opened condition whereby the landing gear door is moved laterally and upwardly relative to the aircraft landing gear when extended relative to the aircraft structure. A gear door actuation assembly (40) is operatively connected to the door support bracket (22) for moving the door support bracket and the gear door supported thereby between the closed and opened conditions thereof. The gear door actuation assembly will include an over-the-center spring assembly (50) which assists in pivotal movement of the door support bracket (22) and the gear door (12-1) supported thereby from the closed condition into the opened condition thereof.

    摘要: An actuator assembly includes an actuation member, a release member, and a source of pressurized gas, wherein during a normal mode of operation, the actuation member and the release member are engaged to move in unison, and wherein during an emergency mode of operation, pressurized gas automatically decouples the actuation member from the release member to move separately. In accordance with yet other aspects of the present disclosure, an electro-mechanical actuator includes an electro-mechanical drive system and an integrated backup system operated by a gas generator, wherein when the backup system is activated, the electro-mechanical drive system is decoupled and the actuator moves to a predetermined position and mechanically locks in place.
