Product Code:SAE ARP5754
Title:Electromechanical Actuator (EMA), General Characteristics & Guidelines for Aircraft Control
Issuing Committee:A-6b3 Electro-Mechanical Actuation Committee
Scope: Define the general characteristics and guidelines for the design of Electro-mechanical Actuator (EMA) for flight control applications or other safety critical applications. This document with provide a boilerplate for air vehicle designers to develop actuation system specifications and guidance to the EMA designers on the key characteristics, their rationale and interpretative material on the meaning and explanation of various terms and definitions on the requirements to be specified through procurements specifications for each application. It will also include guidance material on key verification and validation requirements to demonstrate the compliance of the performance, operational, maintenance (including health monitoring) and safety requirements.
