Terminology and Definitions for Aerospace Fluid Power, Actuation, and Control Technologies
|Publication Date:||1 September 1994|
This document comprises the technical terms and nomenclature together with their definitions and abbreviations used in the field of aerospace fluid power, actuation, and control technologies. The terms listed herein, both general and specific, are believed to be most useful as a reference in the design of future aerospace vehicle fluid power, actuation, and control systems.
Field of Application:
The data contained herein applies to all types of aerospace vehicles including manned and unmanned aircraft, fixed and rotary winged aircraft, commercial and military aircraft, missiles and space systems and their related fluid power, actuation, and control systems.
The purpose of this revised document is to present an updated version of the original document dated 27 April 1991. As an updated document it contains a number of subsections concerning current technology which were not covered originally, e.g., Space Terminology, Fluidics, and Terminology of Aerospace Vehicles in Flight.
In order to achieve the intended purpose and meet SAE Standards, the following guidelines have been established:
a. Use the outline prepared and approved by the SAE A-6 Panel sponsoring this revised document, which is represented by the Table of Contents.
b. Use "SAE Format Guidelines for the Electronic Capture of SAE Documents" dated November 21, 1989 and "SAE Guide for Preparation of Aerospace Documents, AS, ARP, AIR, MA, and MAP" dated January, 1987.
c. Use recommendations of users which apply to the basic equipment and tasks that come under the A-6 Committee.
d. Use terms suggested or recommended by SAE and A-6 Committee members.
e. Comply with SAE Technical Board Policy on Metrication, Metric units (SI).
f. Identify terms common with DP 8625 as agreed in Harmonization Meeting.
The primary source for added terms and definitions to this revised document has been from the recommendations and suggestions of members of the SAE A-6 Committee.
Other sources include:
a. SAE documents which listed terms but were not used because of the Ground Rules in effect on preparation of the original document.
b. Industry and government technical reports associated with SAE activities containing terms and definitions that have common acceptance and usage.
The selection of terms has been based on recommendations that recognized a need for a standard definition or a void, i.e., terms in frequent use but not covered by a definition: e.g., bootstrap reservoir, or mission adaptive wing.
When a term is used in more than one discipline it may have different applications and consequently the definitions vary. Where this occurs in this document, the capital letters (A), (B), etc. are used to distinguish such.
