Hydraulic Pump Minimum Inlet Pressure Test
This SAE Aerospace Recommended Practice contains technical information for conducting and evaluating Minimum Inlet Pressure for Hydraulic Piston Pumps. The methods used were prepared by system designers and hydraulic engineers from the aerospace industry and government services as part of the SAE Committee A-6, Aerospace Fluid Power, Actuation, and Control Technologies, committee meetings. This practice is intended to provide a standard method to compare pump performance and is not intended to replicate aircraft architecture.
This ARP will supplement Minimum Inlet Pressure Tests defined in SAE-AS-595 paragraph 6.12 and SAE-AS-19692 paragraph 18.104.22.168.10.9 by providing lessons learned on setups and methods to minimize variation of test results. The ARP will address the impacts of system variables such as fluid conditions and inlet pressure rate of change.
