  • Aircraft landing gear
    Patent number: 9266606
    Abstract: An aircraft landing gear including: a main strut having an upper portion arranged to be coupled to the underside of an aircraft and a lower portion telescopically mounted with respect to the upper portion; a bogie including a bogie beam pivotally coupled to the lower portion of the main strut, the bogie beam having a plurality of axles mounted on it, each axle carrying one or more wheel assemblies; an actuator 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 having a first configuration in which it permits control fluid to be supplied to the control port of the actuator at a first pressure and a second configuration in which the control valve permits the supply of control fluid to the control port at a second pressure less than the first pressure so as to reduce loads
