This SAE Aerospace Standard (AS) establishes the general requirements for the design, construction, acceptance, and qualification testing of flat cut-off pressure compensated, variable delivery hydraulic pumps used in military aircraft hydraulic systems. It also provides parameters for a Procurement Specification to be used in conjunction with this AS. The hydraulic pumps defined by this AS are generally for use in aircraft hydraulic systems conforming to and as defined in AS5440 and MIL-H-8891, as applicable. NOTES: 1. Hydraulic pumps may incorporate features such as a clutch in the input drive, which will not be covered by this standard. 2. AS595 should be used for commercial aircraft hydraulic pumps. 3. This document should not be used for hydraulic pumps in Electro-Hydrostatic Actuator applications (EHAs).

This SAE Aerospace Information Report (AIR) is a review of the general characteristics of power sources that may be used to provide secondary, auxiliary, or emergency power for use in aircraft, space vehicles, missiles, remotely piloted vehicles, air cushion vehicles, surface effect ships, or other vehicles in which aerospace technology is used. The information contained herein is intended for use in the selection of the power source most appropriate to the needs of a particular vehicle or system. The information may also be used in the preparation of a power source specification. Considerations for use in making a trade study and an evaluation of the several power sources are included. More detailed information relating to specific power sources is available in other SAE Aerospace Information Reports or in Aerospace Recommended Practices.

This Specification covers constant displacement hydraulic motors, generally remotely mounted, using hydraulic fluid under pressure as the energy transfer medium for driving various accessories. Hydraulic motors shall be suitable for use in aircraft hydraulic systems conforming to and as defined in MIL-H-5440 and MIL-H-8891 as applicable.
