A semi-levered landing gear for an aircraft comprising: a main shock absorber strut with upper and lower telescoping portions, with the upper portion connectable to the airframe; a bogie beam to extend fore and aft of the airframe with at least one forward axle and one aft axle for respective forward and aft wheels (7, 7') and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut; and an auxiliary actuator having an upper connector pivotally connected to the upper portion of the main shock absorber strut and a lower connector pivotally connected to the bogie beam at an auxiliary pivot, the auxiliary actuator comprising a two stage telescopic hydraulic unit comprising an outer casing with a first stage piston and cylinder actuator and a second stage piston and cylinder actuator operating coaxially within the outer casing, wherein the first stage actuator provides damping of pivoting movements of the bogie beam about the main pivot and is operable to an extended position and the second stage actuator is operable between a retracted position and an extended position and serves to control the tilt position of the bogie beam relative to the main shock absorber strut, the second stage actuator, when in the retracted position with the first stage actuator in the extended position, limiting the length of the auxiliary actuator between the upper and lower connectors so as to assume a predetermined intermediate length in which the bogie beam is restrained to tilt about the auxiliary pivot and the landing gear is lengthened during take-off of the aircraft, and the second stage actuator, when in the extended position with the first stage actuator in the extended position, allowing the length of the auxiliary actuator between the upper and lower connectors to assume a predetermined maximum length in which the bogie beam is tilted about the main pivot to a stowing position for stowing the landing gear in the aircraft, characterized in that the second stage actuator is operable between a retracted position and an extended position defined by respective end stops within the outer casing and each of the first and second stage actuators incorporates a piston rod (60, 65) which extends from a respective end of the casing and is connected to a respective one of said upper and lower connectors. a main shock absorber strut with upper and lower telescoping portions, with the upper portion connectable to the airframe; a bogie beam to extend fore and aft of the airframe with at least one forward axle and one aft axle for respective forward and aft wheels (7, 7') and a main pivot between the forward and aft axle pivotally connected to the lower portion of the main shock absorber strut; and an auxiliary actuator having an upper connector pivotally connected to the upper portion of the main shock absorber strut and a lower connector pivotally connected to the bogie beam at an auxiliary pivot, the auxiliary actuator comprising a two stage telescopic hydraulic unit comprising an outer casing with a first stage piston and cylinder actuator and a second stage piston and cylinder actuator operating coaxially within the outer casing, wherein the first stage actuator provides damping of pivoting movements of the bogie beam about the main pivot and is operable to an extended position and the second stage actuator is operable between a retracted position and an extended position and serves to control the tilt position of the bogie beam relative to the main shock absorber strut, the second stage actuator, when in the retracted position with the first stage actuator in the extended position, limiting the length of the auxiliary actuator between the upper and lower connectors so as to assume a predetermined intermediate length in which the bogie beam is restrained to tilt about the auxiliary pivot and the landing gear is lengthened during take-off of the aircraft, and the second stage actuator, when in the extended position with the first stage actuator in the extended position, allowing the length of the auxiliary actuator between the upper and lower connectors to assume a predetermined maximum length in which the bogie beam is tilted about the main pivot to a stowing position for stowing the landing gear in the aircraft, characterized in that the second stage actuator is operable between a retracted position and an extended position defined by respective end stops within the outer casing and each of the first and second stage actuators incorporates a piston rod (60, 65) which extends from a respective end of the casing and is connected to a respective one of said upper and lower connectors.
