Aerospace. Electrohydrostatic actuator (EHA). Characteristics to be defined in procurement specifications. | Status: Current, Project Underway

1 Scope This International Standard defines the general characteristics, requirements and design data to be included in the procurement technical specification of an electrohydrostatic actuator (EHA) to be used to power aircraft control surfaces or other moving parts of an aerospace vehicle. This type of actuator is an alternative to the hydraulically powered servo-control actuators that are currently used. It is intended that this International Standard cover the unique requirements of EHAs.
