Organization: SAE
Publication Date: 1 January 2017
Status: active
Page Count: 26
scope:

This SAE Aerospace Recommended Practice (ARP) provides design and test requirements for high pressure, factory pre-charged, welded bellows hydraulic accumulators.

Purpose

The requirements contained in this ARP are compiled for inclusion in a Procurement Specification for this type of accumulator.

NOTES:

As there are many uses for this type of accumulator in aircraft hydraulic systems, the requirements in this ARP should be reviewed by the procuring activity and only those requirements that are applicable for a specific application should be incorporated in the Procurement Specification.

In the event of a conflict between the requirements in this ARP and the Procurement Specification, the Procurement Specification will take precedence.

Field of Application

The accumulator is intended for use in commercial and military aircraft hydraulic systems with rated pressures up to 5000 psi (34474 kPa).

NOTE: As this ARP is for high pressure accumulators, it should not be used for hydraulic reservoirs in Electrohydrostatic Actuator Applications (EHAs). This is because EHA reservoirs are essentially low pressure accumulators and have different technical and qualification requirements.
