This document covers military aircraft wheel and brake equipment.

This SAE Aerospace Standard (AS) sets forth the minimum quality required for aircraft wheel and brake castings. Its use will establish minimum acceptable requirements for internal structure and surface conditions and is predicated on the use of a casting factor for the ultimate load of more than 1.51 through 2.00. When casting factors of 1.25 through 1.50 are used, visual, penetrant, and radiographic or other approved equivalent nondestructive inspection methods shall all be required on each production casting. Where specific parts, or areas of parts, require a quality level exceeding that described by this document, the requirements shall be established by negotiation between the purchaser and vendor.

This standard sets forth the minimum quality required for aircraft wheel and brake castings. Its use will establish minimum acceptable requirements for internal structure and surface conditions and is predicated on the use of a casting factor for the ultimate load of 1.51 (minimum) to 2.00 (maximum). When casting factors of 1.25 minimum to 1.50 maximum are used, visual, penetrant, and radiographic or other approved equivalent non-destructive inspection methods shall all be required on each production casting. Where specific parts or areas require a quality level exceeding that described by this standard, the requirements shall be established by negotiation between the purchaser and vendor.

This SAE Aerospace Standard (AS) defines the configuration of aircraft wheel inflation valve assemblies, including required tolerances, materials, and appropriate finishes.

The purpose of this document is to relate areas where carbon brake technology may differ from traditional steel brake technology in design and performance. Carbon brakes have been used on military aircraft for many years and are now frequently used on newly commercial developed aircraft. This document presents some of the lessons learned.

This SAE Aerospace Information Report (AIR) has been prepared by a panel of the SAE A-5A Committee and is presented to document unique design approaches used for aircraft wheels and brakes.

This SAE Aerospace Information Report (AIR) documents general technical data associated with many of the wheels used in the Air Force.

The focus of this SAE Aerospace Standard (AS) is the integration of thermally actuated pressure release devices, hereafter referred to as fuse plugs, with the wheel and brake assembly. It does not address the manufacturing, quality or acceptance test requirements pertaining to the production of these fuse plugs. It establishes minimum design, installation, qualification, and operational requirements for fuse plugs which are used only in tubeless tire type aircraft braked wheels. Fuse plugs are designed to completely release the contained inflation pressure from a tubeless tire and wheel assembly when brake generated heat causes the tire or wheel to exceed a safe temperature level. The objective is to prevent tire or wheel rupture due to brake generated heat that could cause an unsafe condition for personnel or the aircraft.

The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This test is designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions.

The scope of the test method is to provide stakeholders including fluid manufacturers, brake manufacturers, aircraft constructors, aircraft operators and airworthiness authorities with a relative assessment of the effect of deicing chemicals on carbon oxidation. This simple test is only designed to assess the relative effects of runway deicing chemicals by measuring mass change of contaminated and bare carbon samples tested under the same conditions. It is not possible to set a general acceptance threshold oxidation limit based on this test method because carbon brake stack oxidation is a function of heat sink design and the operating envirnoment.
