Page Count: 40
scope:

This Aerospace Recommended Practice provides general requirements for Electrohydrostatic Module (EHM) that is used in Electrohydrostatic Actuator (EHA) for aerospace applications

This document includes design, performance and test (production and qualification) requirements

Purpose

This document is intended to be used as a guide by the EHA manufacturer in preparing a detail specification for a specific EHM application. This document may be read in conjunction with ISO 22072 which defines the general characteristics, requirements and design data for an Electrohydrostatic Actuator (EHA)

The requirements contained in this document are confined to interface definition and input/output characteristics of an EHM. The information presented should be useful in standardizing

The terminology

The specification of design and performance parameters, and

The test procedures used in conjunction of these components

The requirements do not restrict nor attempt to define the internal design characteristics of an EHM. As such the material is equally applicable to an EHM having

Different internal functioning

Different ratings

Different physical sizes, etc

In certain instances, standards for an EHM design are recommended to achieve component interchangeability, for example, command signal polarity, mounting bolts and fluid ports location

Field of Application

This document applies to both balanced and unbalanced area EHA and EBHA applications

The specification information is directed towards an EHM for use in aircraft flight control systems. However, it shall be recognized that it may also be applicable to many other control systems, for example, landing gear actuation and steering systems. Unless otherwise indicated in the rest of this document, EHA term is used to describe actuators using EHM concept
