This Aerospace Information Report (AIR) has been prepared by a panel of the SAE A-5 Committee and is presented to document the design approaches and service experience from various applications of antiskid systems. This experience includes commercial and military applications.
This information report provides guidance when the ISO International metric tolerance system for limits and fits per ISO/R286 or ANSI B4.2-1978 is applied on a standard, and also provides a selected series of limits and fits for powerplant construction suitable for holes and shafts up to 500 mm. For holes or shafts over 500 mm or for limits and fits not shown, ISO/R286 should be consulted.
The purpose of this AIR is to document some of the valuable lessons learned from several developmental and operational turbine engine monitoring programs. This AIR is not intended to be used as a standard or legal document but rather to provide an objective statement of the more important lessons learned during the development and operation of engine monitoring systems with widely varying operational requirements. It is through the use of ARP 1587 'Aircraft Gas Turbine Engine Monitoring System Guide,' and SP-478 'Aircraft Gas Turbine Engine Monitoring Systems,' an awareness of prior lessons learned and a clear definition of engine operational maintenance concepts that future engine monitoring systems can be developed to meet the specific needs of the user.
Liquid resin and separate catalyst. Primarily for encapsulation, conformal coating, and adhesive applications where dielectric properties are important and a room temperature cure is desired. This specification has been declared "Noncurrent" by the Aerospace Materials Division, SAE, as of March 30, 1987. It is recommended that this specification not be specified for new designs.
This specification covers one type of glass cloth impregnated with a heat-reactive, thermosetting, solution-addition-type PMR-15 polyimide resin system, supplied in the form of continuous rolls of full width cloth or slit tape.
This specification covers an aluminum alloy in the form of drawn seamless tubing 0.029 to 0.500 inch (0.74 to 12.70 mm) in nominal wall thickness. This tubing has been used primarily for structures requiring good fusion weldability and a combination of good strength and resistance to stress corrosion cracking after precipitation heat treatment, but usage is not limited to such applications.
This specification covers an aluminum alloy in the form of drawn, round seamless tubing. This tubing has been used typically for parts, such as brackets, conduits, and low-pressure fluid lines, requiring good weldability, moderate strength, and good resistance to corrosion, but usage is not limited to such applications.
