An Investigation of Air Bearings for Gas Turbine Engines.
Abstract
Future U. S. Army aircraft will require propulsion systems having significantly improved power-to-weight ratio and specific fuel consumption. To attain these goals, simultaneous increases in engine operating pressures and temperatures are required. These ascending performance conditions, with accompanying high rotational speeds, will impose increasingly severe operating requirements on main engine bearings and seals. Because of the high temperatures and high rotational speeds, conventional oil lubrication techniques may not be adaptable to the next generation of small engines. If this should be the case, new lubrication methods will be required. One such method is the air-lubricated (gas) bearing. This report presents a summary of the results of the work performed during the first six months of an investigation of air bearings for gas turbine engines. (Author)
