Abstract
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.
