Hydraulic Power Systems for Trunk Line Aircrafts

Yang Huayong1 Ding Fei1 Ouyang Xiaoping1 Lu Qing2 1.State Key Laboratory of Fluid Power Transmission and Control,Zhejiang University,Hangzhou,310027 2.Institute of Shanghai Aircraft Design and Research,Commercial Aircraft Corporation of China,Ltd.,Shanghai,200232  
The background of developing large commercial aircraft was given.The hydraulic power systems of popular and new type commercial aircrafts from Airbus and Boeing Company were introduced.The future trends of hydraulic system for civil aircraft were outlined,namely high pressure,distributed system,DPHM(diagnostics,prognostics and health management),boostrap reservoir and intelligent pumping source system.The hydraulic power systems of A320 and B737 were compared and the two proposals of hydraulic power system for China commercial aircraft were brought forward.The key techniques of developing commercial crafts,namely high reliability,pressure pulsation control,temperature control and contamination control were indicated.
