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.
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 Standard (AS) defines the configuration of aircraft wheel inflation valve assemblies, including required tolerances, materials, and appropriate finishes.
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 Recommended Practice (ARP) is to provide a recommended minimum laboratory roll performance for main landing gear aircraft wheels without tires installed and applies to both bolted and lock-ring wheel designs for FAA Part 25 and military aircraft main wheels (not required for any nose wheels or main wheels on FAA Part 23, 27 or 29 applications).
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.
