This document covers the performance requirements for solid dry film lubricants, air dried or heat cured, for use in aerospace applications. These lubricants are intended to prevent galling, and may be capable of remaining effective for extended periods of time after exposure to extreme environmental conditions.
Groove designs presented herein are applicable for use with machined or formed metal seals which are similar in configuration to those shown in figure 3, which operate under internal pressure or in vacuum service and which have been specifically qualified or recommended by the purchaser or the manufacturer for use with this AIR. They are also applicable for use with metal o-rings (e.g., MS9142, MS202 thru MS9205) where interchangeability with machined or formed metal seals is desired. For metal o-ring groove designs where inter-changeability is not a requirement refer to ARP 674.
Orientation of the engine, engine axis and coordinate system referred to herein shall be the conventional terminology used in all references to aircraft gas turbine engines.
This specification covers the requirements for format and outline of contents of operating instructions in published form or in manuscript form suitable for publication.
This paper was prepared to support supersession of MIL-S-8879C with Screw Thread Conformity Task Force selected industry standard AS8879C, published by the Society of Automotive Engineers (SAE). Other documentation changes will be covered by separate papers. Separate papers are anticipated for thread gaging issues, and thread gage calibration procedures. The STC-TF decided that the thread design standard needed to be completed before thread gage definition could be addressed. Thread gage definition has to be known before calibration procedures can be addressed.
This SAE Aerospace Recommended Practice (ARP) provides the definition for a control lever connection with 60° "V" serrations for aircraft engine to aircraft power or control levers.
This SAE Aerospace Information Report (AIR) records the dimensions for the No. 70-90, 70L-90, 80-100, and 80L-100 dual rotation propeller shaft ends, which have been deleted from ARP375.
This SAE Aerospace Standard (AS) provides for aircraft reciprocating engines formats for altitude graph sheets recommended for use when presenting engine performance data.
