Duty Cycle Considerations for Electrohydrostatic Actuators
- Aerospace Standard
To enable the comparison of the severity of different EHA/EHM applications. This allows the use of previously qualified designs without the need for repeat testing.
To define parameters for endurance-test design of EHAs; e.g., a way of executing a life-equivalent test in a shorter duration by increasing the speed of cycles and/or the level of applied loads.

A-6B2 Electrohydrostatic Actuation Committee
The Electrohydrostatic Actuation Panel is the panel to promote the advancement of Electrohydrostatic Actuation and control in sciences, technologies, engineering practices, and standards associated with the design, manufacture, operation, and support of Commercial and Military aerospace vehicles. The scope of panel activities shall include the specification, design, development, verification, and support of electrohydrostatic actuators (including their components) and actuation systems by providing information and documents discussing technical information, regulatory updates, recent technology developments, issues related to system development and in service operation and lessons learned. The scope of these efforts will cover primary, secondary, and utility actuation employed on current and future manned and unmanned aircraft, spacecraft, and missiles.
