This SAE Aerospace Information Report (AIR) is a review of the general characteristics of power sources that may be used to provide secondary, auxiliary, or emergency power for use in aircraft, space vehicles, missiles, remotely piloted vehicles, air cushion vehicles, surface effect ships, or other vehicles in which aerospace technology is used. The information contained herein is intended for use in the selection of the power source most appropriate to the needs of a particular vehicle or system. The information may also be used in the preparation of a power source specification. Considerations for use in making a trade study and an evaluation of the several power sources are included. More detailed information relating to specific power sources is available in other SAE Aerospace Information Reports or in Aerospace Recommended Practices.
A-6C4 Power Sources Committee
This document recommends general gland design criteria for static and dynamic O-ring seal applications specifically for engines and engine control systems.
A-6C2 Seals Committee
This method is designed to evaluate the coking propensity of synthetic ester-based aviation lubricants under two phase air-oil mist conditions as found in certain parts of a gas turbine engine, for instance, bearing chamber vent lines. Based on the results from round robin data in 2008–2009 from four laboratories, this method is currently intended to provide a comparison between lubricants as a research tool; it is not currently a satisfactory pass/fail test. At this juncture a reference oil may improve reproducibility (precision between laboratories); a formal precision statement will be given when there is satisfactory data and an agreed on, suitable reference oil if applicable.
E-34 Propulsion Lubricants Committee
This SAE Aerospace Recommended Practice (ARP) outlines the design and functional requirements for aircraft passenger lifts, operated manually and self-propelled. The primary function of the lift described in this document is to act as an elevator between ground level and aircraft doorsills to a maximum of 144 in.
AGE-3 Aircraft Ground Support Equipment Committee
This document provides information, guidelines, and practices for the application, use, and administration of two-dimensional and three-dimensional droplet impingement and ice accretion computer codes. The codes provide computational simulations of inflight icing that predict droplet trajectory, water loading, and ice accretion on aircraft components. These ice accretion characteristics are used during the aircraft design and certification process.
AC-9C Aircraft Icing Technology Committee
In order to insure that the remanufactured and/or rebuilt steering gear has and maintains the reliability and performance associated with a new OEM steering gear, it is essential that the following procedures be followed; if in-house engineering capabilities are limited, it may be necessary to consult with an outside laboratory to insure all testing methods used meet with the requirements outlined in this paper.
Motor Vehicle Council
The test is designed to evaluate the frontal impact resistance of wheel and tire assemblies used with passenger cars, light trucks and multi-purpose vehicles. The test is specifically related to vehicle pothole tests that are undertaken by most vehicle manufacturers. The scope has been expanded to allow the use of a striker that can be angled to preferentially impact the inboard and outboard wheel flange. For side impact of the outboard rim flange only, please refer to SAE J175. This SAE Recommended Practice provides a procedure to test a wheel or a tire and the test failure criteria. The specific test for a vehicle requires input from a pothole test on that vehicle to establish the drop height of the striker used in this test.
Wheel Standards Committee
This SAE Recommended Practice covers two levels of high strength structural low-alloy steel bars having minimum Yield Points of 345 MPa (50 ksi) and 450 MPa (65 ksi). The two strength levels are 345 and 450 MPa or 50 and 65 ksi minimum yield point. Different chemical compositions are used to achieve the specified mechanical properties. In some cases there are significant differences in chemical composition for the same strength level, depending on the fabricating requirements. It should be noted that although the mechanical properties for a steel grade sourced from different suppliers may be the same, the chemical composition may vary significantly. The fabricator should be aware that certain compositional differences may effect the forming, welding, and/or service requirements of the material. It is therefore recommended that the fabricator consult with the producer to understand the effect of chemical composition. The products within the scope of this document include bars of the
Metals Technical Committee
This document describes methodologies to determine the causes blow-by oil consumption caused by the power cylinder.
Piston and Ring Standards Committee
This recommended practice covers an instrument which measures and displays angle of deviation of the airstream dependent on mounting location on the aircraft.
A-4 Aircraft Instruments Committee
This SAE Recommended Practice describes the vibration durability testing of a single battery (test unit) consisting of either an electric vehicle battery module or an electric vehicle battery pack that is typically greater than 200 kg in mass and structurally integrated as part of the vehicle. For statistical purposes, multiple samples would normally be subjected to such testing. Additionally, some test units may be subjected to life cycle testing (either after or during vibration testing) to determine the effects of vibration on battery life. Such life testing is not described in this procedure; SAE J2288 may be used for this purpose as applicable. Finally, impact testing, such as crash and pothole, are not included in this procedure. SAE 2464 describes abusive/safety shock tests. Preferably, a specific vibration durability profile should be developed based on actual vehicle measurements for the specific electric vehicle application.
Battery Standards Testing Committee
This recommended practice provides guidance on vehicle Cybersecurity and was created based off of, and expanded on from, existing practices which are being implemented or reported in industry, government and conference papers. The best practices are intended to be flexible, pragmatic, and adaptable in their further application to the vehicle industry as well as to other cyber-physical vehicle systems (e.g., commercial and military vehicles, trucks, busses). Other proprietary Cybersecurity development processes and standards may have been established to support a specific manufacturer’s development processes, and may not be comprehensively represented in this document, however, information contained in this document may help refine existing in-house processes, methods, etc. This recommended practice establishes a set of high-level guiding principles for Cybersecurity as it relates to cyber-physical vehicle systems. This includes: Defining a complete lifecycle process framework that can
Vehicle Cybersecurity Systems Engineering Committee
The purpose of this SAE Recommended Practice is to review factors that influence the behavior of elastomers under conditions of dynamic stress and to provide guidance concerning laboratory procedures for determining the fatigue characteristics of elastomeric materials and fabricated elastomeric components.

These methods cover testing procedures for defining and specifying the dynamic characteristics of simple elastomers and simple fabricated elastomeric isolators used in vehicle components. Simple, here, is defined as solid (non-hydraulic) components tested at frequencies less than or equal to 25 Hz.
Materials, Processes and Parts Council
This SAE Recommended Practice defines a set of measurements and standard procedures for motor vehicle dimensions. The dimensions are primarily intended to measure the design intent of a vehicle within a design environment (i.e., CAD). All dimensions in this practice can be measured this way. In addition, some dimensions can be taken in an actual vehicle. If measurements are taken on physical properties, some differences in values should be expected. Also, care should be taken to not confuse design intent measurements with those taken on a physical property. It is intended that the dimensions and procedures described in this practice be generic in their application to both the HPM, described in SAE J826, and the HPM-II, described in SAE J4002. In some circumstances, the figures may only reflect one or the other. Unless otherwise specified, all dimensions are measured normal to the three-dimensional reference system (see SAE J182), except ground-related dimensions, which are defined
