This document defines the test procedures and performance limits of steady state and transient voltage characteristics for 12 V, 24 V, or 48 V electrical power generating systems used in commercial ground vehicles.
This specification covers a low-alloy steel in the form of bars, forgings, mechanical tubing, and forging or tubing stock.
This supplement forms a part of SAE Aerospace Specification AS85421. It shall be used to identify fitting standards citing this procurement specification.
This specification covers a perfluoroether elastomer in the form of molded rings.
Following a number of high-visibility collisions between aircraft on the airport surface, overall taxi operations have been brought under greater scrutiny. In addition, observation of taxi operations and the results of associated research programs have revealed that the efficiency of taxi operations could be significantly improved with available technologies and by applying a human centered design approach. Surface operations displays have been tested in prototype form and a number of manufacturers are moving toward product definition. This document provides guidance on the design of elements, which may be part of surface operations displays whose objectives would be to enhance safety and to improve overall efficiency of aircraft operations on the airport surface. Such efficiency increases should be realized not only in day-to-day operations, but should also be manifested in training for surface operations. This document sets forth functional and design recommendations concerning the
This SAE Aerospace Information Report (AIR) discusses characteristics of data communications for the Joint Architecture for Unmanned Systems (JAUS). This document provides guidance on the aspects of transport media, unmanned systems and the characteristics of JAUS itself that are relevant to the definition of a JAUS transport specification.
This specification covers an aluminum alloy in the form of pre-alloyed powder.
The primary purpose of the shipping closure is to protect the aircraft parts or system from damage and foreign material ingress/egress (e.g., dust, dirt or other contaminants) during transport and storage. Shipping closures are not airworthy items. Therefore, their usage is defined as preventative for the parts to be protected as opposed to operational. Military and commercial customer requirements for the prevention of damage or contamination to stored parts are generally limited to the generic instructions “all openings should be sufficiently covered to prevent the entrance of dust, dirt, moisture or other foreign contaminants”. This recommended practice outlines basic minimum parameters for suggested item construction and usage. Additionally, this recommended practice provides instruction on how to apply these closures to various openings.
This specification covers a 100% homopolymer of polychlorotrifluoroethylene (PCTFE) in the form of film and film tape 0.010 inch (0.25 mm) and under in nominal thickness.
The fluid flow treated in this section is isothermal, subsonic, and incompressible. The effects of heat addition, work on the fluid, variation in sonic velocity, and changes in elevation are neglected. An incompressible fluid is one in which a change in pressure causes no resulting change in fluid density. The assumption that liquids are incompressible introduces no appreciable error in calculations, but the assumption that a gas is incompressible introduces an error of a magnitude that is dependent on the fluid velocity and on the loss coefficient of the particular duct section or piece of equipment. Fig. 1A-1 shows the error in pressure drop resulting from assuming that air is incompressible. With reasonably small loss coefficients and the accuracy that is usually required in most calculations, compressible fluids may be treated as incompressible for velocities less than Mach 0.2. At higher velocities and for large loss coefficients (Kt and 4fL/D), compressible flow analysis should
The force, torque, and power methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, surface texture, and non-steady-state tire operations are excluded from the recommended practice because they are still in the research stage.
This specification presents requirements for thin-walled (inside diameter greater than four times the wall thickness and outside diameter 1/4 inch and larger) corrosion-resistant steel tubing in approximately the 1/8 hard condition, of special quality, suitable for use in high-pressure hydraulic systems.
This procedure applies to directional control valves or other valves which in various positions direct or block fluid flow as applied to Off-Road Self-Propelled Work Machines as referenced in SAE J1116.
This document establishes the requirements for screw-on type reattachable couplings for use in low temperature hose assemblies.
The heating value or heat of combustion is a measure of the energy available from the fuel. The fraction or percentage of the heat of combustion that is converted to useful work is a measure of the thermal efficiency of an engine. Thus, a knowledge of the heat of combustion of the fuel is basic to the engineering of automotive engines. This SAE Information Report provides information on the standardized procedures for determining the heat of combustion of fuels that may be used for automotive engines. The changes to SAE J1498 include: SAE Publications - Added SAE Paper 2010-01-1517 Other Publications and Sections 5, 9, and 10 - Updated ASTM alphanumeric designations and titles. Section 10 - Added discussion of a method to calculate net heating value for gasoline-ethanol blends using ASTM D3338.
This specification covers the specific requirements for 5052 aluminum alloy plate and sheet; the general requirements are covered in AMS-QQ-A-250.
