This SAE Recommended Practice covers the design and application of a 120 VAC single phase engine based auxiliary power unit or GENSET. This document is intended to provide design direction for the single phase nominal 120 VAC as it interfaces within the truck 12 VDC battery and electrical architecture providing power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off.
This SAE Recommended Practice covers passive torque biasing axle and center differentials used in passenger car and light truck applications. Differentials are of the bevel gear, helical gear, and planetary types, although other configurations are possible.
This specification provides dimensional standards for crimp type contact wire barrel design and is a replacement for MS3190. Some wire barrel designs may exist in AS39029 but are not considered approved for future use, therefore, will not appear in this specification. The crimp barrel sizes listed in this document have been standardized in AS39029 and AS22520 specifications, tools and contacts are available to support these listed sizes. These crimp barrel requirements shall be used for any contact, regardless of whether it is a standard or non-standard contact configuration. The specification lists details for three types of wire barrels: A, B, and C. Wire barrel type A is not recommended for new design. Table 4 lists each AS39029 detail sheet wire barrel type.
This material type has resistance to hot air, but generally has poor resistance to fuels and lubricants, but usage is not limited to such applications. Each application should be considered separately. This material type has a typical service temperature range of -85 to 500 °F (-65 to 260 °C). The operating temperature range of the material is a general temperature range, but the presence of particular fluids and design parameters may modify this range. Recommendations on the material selection are based on available technical data and are offered as suggestions only. Each user should make his own tests to determine the suitability for his own particular use.
This SAE Aerospace Standard (AS) establishes a uniform procedure for calculation of electron vacancy numbers in superalloys. It is intended for use by suppliers of raw materials and parts, typically castings, for which control of electron vacancy number is required by the raw material specification.
This procurement specification covers inserts made from A286 alloy of the type identified under the Unified Numbering System as UNS S66286 which have self-locking internal threads and integrated locking keys to positively secure the insert against rotation when properly installed in threaded holes.
This SAE Metric Aerospace Standard (MA) provides for helical coil screw thread inserts, both free running and self-locking, installation screw thread dimensional data and guidance on insert length selection. The document also provides formulas for determining requirements when non standard insert lengths are necessary.
The reader of specifications sometimes needs help understanding the format of an AMS and reasoning behind certain usage of terms. The scope of this AIR is to explain the functions of the various sections of the specifications, why some of the terms in AMS specifications are used, and how the specification system works. After the introduction (Section 3 of this document), the topics are presented in the order they usually appear in specifications.
This standard covers oxygen masks and breathing valves used with both panel mounted and mask mounted demand and pressure-demand oxygen regulators. Mask mounted oxygen regulators are covered under other standards, but when the mask mounted regulator incorporates an integral exhalation valve, the performance of this valve shall meet the requirements of this standard.
This AIR is presented in two parts - the first part, to alert the engineer with respect to the environmental factors which he might have to consider - the second part, as tabular data and figures to which he can refer with respect to a specific geographical location.
This aeronautical standard covers two basic types of instruments as follows: Type I - Pitot Pressure, straight and L-shaped, 12 and 14 volt nominal, 2 wire circuit. Type II - Pitot and Static Pressured, straight and L-shaped, 12 and 24 volt nominal, 2 wire circuit.
This specification establishes requirements for automatic shutoff, quick-disconnect coupling assemblies for fuel and oil lines.
