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 SAE Standard establishes the test procedure, environment, and instrumentation for determining the sound levels of snowmobiles in the stationary test mode. This test method is intended to provide an accurate measurement of exhaust and other engine noise and may be used to evaluate new and in-use snowmobiles to determine compliance with noise control regulations. Sound level measurements obtained with this test method are not intended as an engineering determination of overall machine noise. For this purpose, the use of SAE J192 is recommended.
This SAE Recommended Practice is intended to provide basic information on properties and characteristics of high-strength carbon and alloy steels which have been subjected to special die drawing. This includes both cold drawing with heavier-than-normal drafts and die drawing at elevated temperatures.
This SAE Aerospace Standard (AS) defines the requirements for a heavy-duty polytetrafluoroethylene (PTFE) lined, metallic reinforced, hose assembly suitable for use in high temperature, high pressure, 4000 psi, aircraft and missile hydraulic fluid systems.
This specification covers a silicone (VMQ) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.
This specification covers a chloroprene (CR) rubber in the form of sheet, strip, tubing, extrusions, and molded shapes.
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
This specification covers the requirements for embrittlement relief (baking) of heat treated steel parts to remove hydrogen infused during plating and certain other chemical processing such as stripping, chemical milling, pickling, and etching.
This SAE Standard establishes the test procedure, environment, and instrumentation for determining the exhaust sound pressure levels of motorcycles under stationary conditions. Since initial publication, it has been successfully applied to regulation and monitoring of sound pressure levels of off-highway vehicles, and that remains its recommended application. Users of SAE J1287 for the purpose of roadside enforcement of sound pressure levels for on-highway motorcycles have reported difficulties with its implementation in that application. In response, SAE J2825 was developed, and is recommended for measurement of exhaust sound pressure levels of stationary on-highway motorcycles. Care must be taken not to confuse stationary sound pressure levels with total motorcycle sound pressure levels. This test does not evaluate total motorcycle sound during operation. For this purpose, SAE J331 or SAE J47 is recommended. Any allowable sound limits (dBA) set in relation to SAE J1287 for exhaust
This SAE Aerospace Recommended Practice (ARP) provides guidance for the design and installation of a commercial aircraft hydraulic system to meet the applicable requirements, including the applicable airworthiness regulations that affect the hydraulic system design. This ARP also provides information and guidelines on the many factors that arise in the design process to provide cost effectiveness, reliability, maintainability and accepted design and installation practices.
This specification covers a nitriding grade of aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock. AMS6497 and AMS6498 cover UNS K23280 having other quality levels.
“An Assessment of Planar Waves” provides background on some of the history of planar waves, which are time-dependent variations of inlet recovery, as well as establishing a hierarchy for categorizing various types of planar waves. It further identifies approaches for establishing compression-component and engine sensitivities to planar waves, and methods for accounting for the destabilizing effects of planar waves. This document contains an extensive list and categorization (see Appendix A) of references to aid both the newcomer and the practitioner on this subject. The committee acknowledges that this document addresses only the impact of planar waves on compression-component stability and does not address the impact of planar waves on augmenter rumble, engine structural issues, and/or pilot discomfort.
This standard outlines the conditions that enhance the risk of hydrogen embrittlement of steel and define the relief procedures required to minimize the risk of hydrogen embrittlement. It is intended to control the process.
This document recommends criteria to assure adequate visibility from the flight deck. The flight-deck windshield must provide sufficient external vision to permit the pilot to perform any maneuvers within the operating limits of the aircraft safely and, at the same time, afford an unobstructed internal view of the flight instruments and other critical components and displays from the same eye position.
This specification covers an aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
This specification covers established inch/pound manufacturing tolerances applicable to carbon steel sheet, strip, and plate ordered to inch/pound dimensions. These tolerances apply to all conditions unless otherwise noted. The term “excl” is used to apply only to the higher figure of the specified range. Tolerances for product sizes not listed herein shall be as agreed upon by purchaser and vendor.
This specification covers a copper-nickel-tin alloy in the form of bars and rods.
This specification covers a two-component compound, an epoxy resin base and a hardener, in the form of a paste.
This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
This specification covers an aluminum alloy in the form of sheet laminated with two or more layers of unidirectional aramid fiber/epoxy prepreg.
In the analysis and measurement of residual stresses of materials, it has been noted that there are frequently differences in interpretation of the terms "macrostrain" and "microstrain." To assist communication among research personnel in this area, definitions for these two terms are suggested by the Fatigue Design and Evaluation Committee of SAE. Since "macrostress" is commonly computed from "macrostrain" in residual stress analysis, to be consistent, the definitions given are for "macrostrain" and "microstrain."
This specification covers a premium aircraft-quality, low-alloy steel in the form of bars, forgings, mechanical tubing, and forging stock.
This document recommends design criteria for an Automatic Braking System. The ABS shall enhance braking performance under most aircraft configurations and all runway conditions.
This specification covers carbon steel (1025) tubing of aircraft quality.
This specification covers an aluminum alloy in the form of extruded bars, rods, wire, profiles, and tubing 2.000 inches (50.80 mm) and under in nominal diameter or least thickness (wall thickness of tubing) with a maximum cross-sectional area of 20 in2 (129 cm2), and a maximum circle size of 10 inches (254 mm) (see 8.8).
