Study on bootstrap reservoir type pressurized system for civil aircraft hydraulic supply system

Bootstrap reservoir type Pressurized system is designed to maintain the return pressure in the reservoir to ensure the pumps working without cavitation. Different pressurized systems for the bootstrap reservoirs are analyzed and then the hydraulic type pressurized system for the civil aircraft hydraulic reservoir is selected and designed. Then the bootstrap pressure, pressure maintaining time, assistant flow capacity of the selected hydraulic type bootstrap reservoir is simulative calculated. Finally, the EDP restarting and full flow working profile is used to confirm the designed hydraulic type bootstrap pressurized system is confirmed to be suitable of the civil aircraft system.
