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. (Reference: U.S. Department of Transportation FAA Advisory Circular No. 23-17C; Title 14, Code of Federal Regulations (14 CFR) Part 25.735 (j); U.S.

This SAE Aerospace Recommended Practice (ARP) is intended to provide guidance on verifying the integrity of inflation pressure sealing systems of aircraft wheel/tire assemblies.

This SAE Aerospace Recommended Practice (ARP) specifies the minimum design and qualification test recommendations for aircraft wheel overpressurization release devices used with tubeless aircraft tires to protect from possible explosive failure of the contained inflation chamber due to overinflation. Devices of this type provide a means, but not the only means, for showing compliance to Subsection 25.731(d) of Part 25 of Title 14 of the Code of Federal Regulations. Devices of this type will not protect against flash fire explosive conditions within the inflation chamber which may occur due to extremely overheated brakes or spontaneous combustion caused by a foreign substance within the inflation chamber. To help protect against this condition, nitrogen (N2) or other inert gas should be used for inflation.

A panel of the SAE A-5A Committee prepared this SAE Aerospace Information Report (AIR). The document describes the design approaches used for current applications of Brake-by-Wire (BBW) control systems that are used on commercial and military airplanes. The document also discusses the experience gained during service in the commercial and military environments, and covers system, ergonomic, hardware, and development aspects. The treatment includes the lessons that have been learned during application of the technology. Although there are a variety of approaches that have been used in the design of BBW systems, the main focus of this document is on systems that use the electro-hydraulic method of control. The overall range of implementations is briefly described in 2.3. Sections 3, 4, and 5 describe the electro-hydraulic method in detail.

This document suggests the maintainability features which should be considered in the design of aircraft wheels and brakes. The effect on such factors as cost, weight, reliability, and compatibility with other systems should be considered before incorporation of any of these features in the design.

This standard establishes minimum design, installation, qualification, and operational requirements for thermally actuated, pressure release devices for use only in tubeless tire type aircraft wheels. These devices are designed to completely release the contained air pressure from a tubeless tire and wheel assembly when absorbed and/or brake generated heat causes the tire or wheel to exceed a safe pressure/temperature/load operating level. The objective is to prevent tire or wheel rupture from brake generated heat which could cause serious personnel injuries or serious aircraft operational hazards.
