DIGEST A description of the application of Axial Face Seals to Aircraft Gas Turbine Main Shaft Bearings, Gear Boxes or Accessory Pads and Accessories; their limitations with respect to sealing media, temperatures, pressures and rubbing surface speeds; the influence of these factors on the selection of materials of construction. A statement of the current status of the art and projected future requirements.

The Controlled Gap Seal consists of a carbon sealing ring with a steel retaining ring shrink fitted on the outside diameter, two steel mating rings, a spacer ring, and an outer shell. In operation under ideal conditions there is a pressure differential across the seal with the air side pressure being higher than the oil side. This differential prevents oil leakage and holds the carbon sealing ring against the oil side mating ring while the shaft turns freely within the sealing ring. The Controlled Gap Seal will operate with unlimited axial movement, is of rugged construction and will give long life and very low heat generation. It is good for high temperature operation since there are no rubber or plastic materials used.

This paper describes some of the problems encountered in sealing various media in aircraft gas turbine engine main shaft and accessory drive applications. The major types of seals are illustrated, and the individual design and operating limits of each are discussed. The seal performance requirements for the present and near future gas turbine engines are indicated. An evaluation program directed towards the development of a seal materials combination which will be compatible for extremely high speed and high temperature operation is described and some tests results enumerated. The equipment used for testing of materials and complete seal assemblies is described and pictured.

This standard provides a method of applying surface roughness, waviness and lay control. The data included herein also covers the method of applying surface roughness symbols and related designations to drawings and specifications of parts when applicable. This standard is based on the Arithmetical Average (AA) method of instrumentation. Data compiled are based on current manufacturing practices. It also includes a summary of data published in the latest issue of the American Standards Association publication ASA B46.1.

To establish design recommendations that will provide a basis for safe and reliable connections to threaded screw- or stud-type electrical equipment terminations. These recommendations are directed primarily, but not solely, to the aerospace and ground support equipment industries. Since individual design criteria may alter the details as outlined, it is therefore important that this Aerospace Information Report (AIR) not be considered mandatory, but be used only as a design guide.

Certain techniques involved in determining the dirt or abrasive content of aircraft greases are considered inadequate. It is desirable to develop a method of analysis which will definitely identify the quantity, size, and degree of abrasiveness of foreign substances in lubricating greases.
