An aircraft undercarriage suspension includes a liquid filled telescopic suspension strut and a gas spring. Liquid displaced by the strut into the gas spring is selectively directed through alternative flow restrictors, one of which is matched for optimum damping during aircraft landing and the other of which is matched for optimum damping during taxing. A ride control valve operates on the nose wheel undercarriage to control aircraft pitching, the ride control hydraulic system being separated from the damping oil by a floating piston.

Aircraft undercarriage suspension

An aircraft undercarriage includes a liquid filled telescopic suspension strut and a compressed gas chamber separated from the liquid in the strut by a floating piston. Liquid is added to or taken away from the strut by a ride control valve operated by a ride control mechanism sensitive to relative displacement of the airframe and undercarriage wheel so that the aircraft is maintained at a constant height during taxiing. Shut-off valves isolate the strut from the hydraulic system of the aircraft during flight and landing touchdown.
