Comparative laboratory performance of air brake cylinder lubricants

A test method for measuring the low temperature release time and the high temperature cup we ar preventive properties of air brake cylinder lubricants is described. The results of comparative trials of reference and various proprietary lubrlcants are given. Again, a non- soap thickened polyglycol grease containing MoS2 was best at 150°F. ...

The performance of prorietary and AAR specification brake cylinder lubricants at 150ºF. and -50ºF.

The performance of AAR Specification 914 -42 and 914 - 62 and proprietary lubricants , in IQ - in. air brake cylinders, was compared at 150°F . and at - 50°F. A proprietary non- soap thickened polyglycol grease, containing MoS2, was best in endurance tests at 150° F. and in piston release time comparisons at - 50°F . AAR 914 -42 Specification...

Pressure probes in free molecule flow

When the mean free path becomes a significant fraction of a characteristic dimension of a pressure probe, the usual continuum formulae relating the measured pressure to the free-stream pressure and Mach number are no longer valid. The present paper treats the case where the mean free path is so large compared with the probe diameter that...

Recent trends in the mechanics of highly rarefied gases

A review of some recent investigations in the flow of h i ghly rarefied gases is presented. The basic nature of the transport process in free molec ule flow is deduced from the Boltzmann equation for the molecular velocity distribution function. The present semiempirical state of our knowledge of the reflection of molecules from the surface of a...
