Standard
AMS6372G
This specification covers an aircraft-quality, low-alloy steel in the form of mechanical tubing. This tubing has been used typically for parts, 0.75 inch (19 mm) and under in section thickness at time of heat treatment, requiring a through-hardening steel capable of developing hardness as high as 40 HRC when properly hardened and tempered and for parts of greater thickness but requiring proportionately lower hardness, but usage is not limited to such applications.

Standard
AS1072B
This standard defines the requirements for bulk protective sleeve to provide fire resistance for aircraft hose assemblies, which will enable these assemblies to meet the requirements of AS 1055. Note: Use of this sleeve does not eliminate the need to demonstrate that the sleeved assemblies will meet the applicable requirements of AS1055.

This specification covers lightweight hose assemblies intended for use in high-temperature, 204 °C degrees, high-pressure, 21 000 kPa (210 bar) aircraft hydraulic systems, also for use in pneumatic systems which allow some gaseous diffusion through the PTFE wall.

Abstract RCA has developed a unique technique for the early detection and identification of rolling element bearing failures within gearboxes. This unique technique is not dependent upon any previous measurement taken on the gearbox under test and does not require the collection of data over a lengthy time period for trend analysis. A hand-held analyzer has been constructed that successfully detects minor spalling damage in the ball and roller bearings in a variety of gearboxes.

Turbocharged engines are more exacting than naturally aspirated engines both as regards lubricating oils and engine main components - particularly crankshaft and rod bearings - since they have to cope with the increased loads arising from higher combustion pressures. These problems can be partly solved by improved oil filtration in the lubrication circuit. An effective solution is the so called double filtration. The double filtration filter, described in this paper, is composed of two sections housed in one standard easy-change cartridge. Each section has a specific function: fine filtration in the by-pass section and coarse filtration in the full-flow section. Structure of filter, filtration characteristics and engine test results are described here. Further possible developments are also mentioned.

This paper presents a simultaneous solution of both Reynolds equation for hydrodynamic lubrication and Laplace's equation for a porous matrix, the continuity of pressure at film-bearing interface being maintained. Performance characteristics for an infinitely long bearing are obtained and design charts comprising optimum curves for maximum load capacity, minimum friction loss and maximum utilization of bearing bush porous material are displayed.

Results of experiments conducted on complete as well as partial porous journal bearings operating under steady conditions are herein presented. Performance characteristics presently determined include eccentricity ratio, coefficient of friction and attitude angle. Values of the permeability parameter ranged in experiments between 2.54×10−3and 4.35×10−2. Test results show quite good agreement with theoretical predictions of the authors. Comparison between results obtained for partial bearings, also for complete bearings with holes intensionally drilled in the region of supposedly negative pressure implies the validity of discarding the negative pressure zone as postulated by the authors in their proposed theory.
