This SAE Aerospace Recommended Practice (ARP) is an application guide for fixed and variable displacement hydraulic motors. It provides details of the characteristics of fixed and variable displacement hydraulic motors, architectures, circuit designs, controls, and typical applications. The applications include airborne and defense vehicles with emphasis on high performance applications.
There is a need for a document to provide guidance to aerospace engineers for understanding and characterizing hydraulic motors for a variety of high speed/high performance aerospace applications. This document provides information that supplements and can be used with accepted industry specifications.
