Abstract: Main developmental trend of aircraft, especially military aircraft, hydraulic systems is summarized. And some research works on aircraft hydraulic systems of domestic and overseas are introduced. Light, smallness, high pressure, high power, variable pressure, etc. are the main developmental trend of aircraft hydraulic systems. Especially, high pressure variable pressure hydraulic pump source is very important for the development of future aircraft.

Key words: aircr aft hydraulic systems, high-pr essur e, variable pressure
