Abstract
A mechanism for increasing the ride height of aircraft by selectively increasing the hydraulic fluid content within landing gear struts. By increasing the hydraulic fluid volume within a strut, the strut is lengthened without adversely affecting its spring rate while the ability to withdraw fluid from a strut maintains the ability of the strut to absorb the impact of landing. The mechanism is readily retrofitable to existing landing gear systems to accommodate more efficient under the wing intake designs and to reduce the likelihood of FOD during taxiing at minimal cost and with very a minimal increase in the aircraft weight.
