Pyropolycarboranes: The base for self‐lubricating materials with gas lubricant

Journal of Applied Polymer Science, 1979
AbstractThis paper reports the results of an investigation of pyropolycarboranes, nondeformable thermally stable cross‐linked polymeric materials obtained by pyrolysis of carborane‐containing polymers. Carborane‐containing polyamides and polyesters were heated in air under pressure and analyzed by thermomechanical and thermogravimetric methods ...

Lubrication of GAS TURBINES

Scientific Lubrication, 1956
MAKERS OF STATIONARY GAS TURBINES for industrial uses claim that the lubricating cost of medium-size power units ranges between 1 and 2% of the fuel costs. Comparative figures for average Diesel engines are 5 to 10%. These savings have an effect on the total running cost economy.

Gas-Lubricated Bearings

2017
Abstract This article describes the characteristics of three types of gas bearings, such as aerostatic bearing, precision aerodynamic bearing (PAB), and compliant aerodynamic bearing (CAB). It discusses the applications for aerostatic bearings and advantages in lubricating a bearing with a compressible gas. The article also describes the

Gas Lubricated Spherical Bearings

Journal of Basic Engineering, 1963
The gas lubricated hemispherical bearing is considered theoretically. First, the isothermal Reynolds’ equation for a thin film between arbitrary curved surfaces is derived. The equation is then applied to a hemispherical bearing. External pressurization is considered by assuming a “point” source at the pole.

Synthetic Lubricants for Gas Turbines

Aircraft Engineering and Aerospace Technology, 1961
SINCE the Second World War, no lubrication problem has offered a greater challenge to chemists than that posed by the aircraft gas turbine engine. Mineral oils, which for many years had provided satisfactory lubrication of piston‐engined aircraft, had obvious limitations when considering jet engines, and more than ten years ago the need for new ...

A review of progress in gas lubrication

Reviews of Physics in Technology, 1970
The past decade has witnessed a rapid evolution in the technology of gas lubrication which has been accompanied by the application of gas bearings on an increasing scale. Before 1960, existing applications were restricted to two specialized areas: gyroscopes for inertial navigation and gas circulators in nuclear reactors.

On the Dynamics of Gas Lubricated Triboelements

ASME/STLE 2007 International Joint Tribology Conference, Parts A and B, 2007
Gas lubricated triboelements are ubiquitous in many applications, from gas turbines seals, high speed dental drills, cryogenic refrigerators, oil-free bearings for turbo chargers, to read-write self acting heads in magnetic recording. In all these application the film must be maintained sufficiently precise especially in the presence of disturbances ...
