摘要： An actuator arm lock (28) suitable for use with an actuator (10) which has an actuator arm (14) and an actuator body (12) is disclosed. The actuator arm lock (28) comprises a lock ring (26) suitable for clamping around an actuator arm (14). The lock ring (26) comprises a circumferentially extending element (30) and a locking element (32). The circumferentially extending element (30) comprises first and second element ends (34, 36) and an inner surface (74) which faces towards the actuator arm (14) when the actuator arm lock (28) is in use, and the circumferentially extending element (30) is configured to partially extend around the actuator arm (14). The locking element (32) comprises first and second locking ends (44, 46) and is configured to extend at least between the first and second element ends (34, 36) of the circumferentially extending element (30). The first locking end (44) of the locking element (32) is engaged with or engageable with the first element end (34) of the circumferentially extending element (30), and the locking element (32) is engaged with or engageable with the second element end (36) of the circumferentially extending element (30). The locking element (32) may be reversibly reconfigured between a locked configuration in which the actuator arm lock (28) clamps onto the actuator arm (14), and an unlocked configuration in which the actuator arm lock (28) is loose on the actuator arm (14).

摘要： A pin assembly for insertion into a pin joint (4) of an aircraft landing gear (2) is disclosed. The pin assembly includes a reservoir (18) for storing a lubricating agent and a piston (22) mounted for reciprocal movement within the reservoir (18), the piston (22) dividing the reservoir into a first chamber (19a) and a second chamber (19b). A bi-directional flow path between the first and second chambers (19a, 19b) via the surface to be lubricated (33, 37) is provided by means of a first bi-directional flow path between the first chamber (19a) and the exterior of the pin assembly and a second bi-directional flow path between the second chamber (19b) and the exterior of the pin assembly. A pin assembly including an indicator system, and a pin insert in the form of a replaceable cartridge is also disclosed along with associated methods.

摘要： A retractable landing gear on an aircraft is operated by a landing gear control system 20 having a manually operable lever 26 movable from a first, e.g. gear-down, position to a second, e.g. gear-up position, in response to which a signal (e.g. a gear-up command) is outputted causing the landing gear to move to an up position. The landing gear control system 20 also includes a motor 40 configured to move the lever 26 in dependence on a signal, for example a signal received by a landing gear lever control unit 42 from a take-off detection system 46 which indicates that the aircraft has taken-off. Thus, the lever 26 may be considered as being configured both to be operated by a pilot of the aircraft manually and to be operated by the motor automatically.

摘要： An aircraft landing gear structure (18, 152) according to the present disclosure includes a retract actuator (32) and a shrink mechanism (22). The retract actuator (32) is configured to transition a strut assembly (100, 154) of the aircraft landing gear structure (18, 152) between an extended configuration (74) and a retracted configuration (72) via the shrink mechanism (22), thereby reducing the overall longitudinal length of the strut assembly. The retract actuator (32) is also configured to retract the aircraft landing gear into a stowage area of the aircraft during flight, via a retraction mechanism. In some examples, the retraction mechanism is a walking beam that rotates about a retraction axis to retract the aircraft landing gear structure, while simultaneously actuating the shrink mechanism (22), such as via a drive link coupling the retraction mechanism (32) and the shrink mechanism (22). In some examples, the shrink mechanism (22) is mechanically slaved to the retraction mechanism. The shrink mechanism (22) is a locking link assembly in some examples.
