ABSTRACT:
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.
