摘要:
An aircraft landing gear (10, 50) including: a main strut (12) having an upper portion (12a) arranged to be coupled to the underside of an aircraft and a lower portion (12b) telescopically mounted with respect to the upper portion; a bogie including a bogie beam (14) pivotally coupled to the lower portion of the main strut, the bogie beam having a plurality of axles (16a, 16b) mounted on it, each axle carrying one or more wheel assemblies; an actuator (20, 60) arranged such that a change in its effective length causes a change in the angular position of the bogie relative to the main strut, and a control port arranged to be coupled to a control fluid supply system, wherein the aircraft landing gear includes or is in combination with a control valve (40) having a first configuration (42b) in which it permits control fluid to be supplied to the control port of the actuator at a first pressure (p) and a second configuration (42a) in which the control valve permits the supply of control fluid to the control port at a second pressure (R) less than the first pressure so as to reduce loads experienced by components of the actuator during taxiing.
