SAE ARP 5879:2010 PDF Download

The SAE ARP 5879:2010 standard provides an overview of the tests and issues specific to Electrohydrostatic Actuators (EHAs). An EHA is a system that combines a hydraulic actuator, an electric servomotor, and a hydraulic pump to control movement. This standard discusses the tests necessary for EHAs and the methodologies used to achieve the testing objectives.

The document also includes a list of tests that are not unique to EHAs but are still applicable. For these tests, the reader is referred to ARP1281, a separate standard that addresses test issues for electrohydraulic flight control servoactuators used in aircraft flight controls.

It is important to note that the standard does not provide numerical definitions or specifications for the test parameters to be imposed or measured. These definitions and specifications should be developed in accordance with the requirements of the applicable EHA technical specification document and consider factors such as instrumentation accuracy and test temperature.
