Extract

Hydraulic systems are used extensively in aircraft for actuating flight control and other surfaces and in retraction, steering and braking mechanisms. Their weight is of the order of 9% to 13% of the payload in present day civil aircraft and about twice these values in military aircraft. This investigation is aimed at finding whether lighter and more compact systems would result from a change of working pressure and at providing general relationships in the form of dimensionless curves to enable designers readily to optimise aircraft hydraulic systems.
