摘要
Abstract
For a certain type of aircraft, the hydraulic reservoir pressurization system is a hybrid of hydraulic oil and gas.Aimed to solve the failure of the hydraulic reservoir pressurization system's pipeline and a part of the airborne products, a new hydraulic reservoir pressurization system is designed.By the use of membrane water separation from the air principle, a reservoir pressurization unit is developed.This reservoir pressurization unit has three functions,which are air filter, water separation and air depressurization.By the use of the extruded non-flaring tube, the whole aircraft's reservoir pressurization pipes and related accessories are optimized.The main performance of before and after the design improvement, the improved system and a certain type of Airbus' aircraft are analyzed and compared separately.Test results show that the maintainability of the hydraulic reservoir pressurization system is improved, weight of the aircraft and failure rate of the system are reduced.关键词
