The following report represents a compendium of selected speaker presentation materials and observations made by Prof. O. Pinkus at the NASA/ASME/Industry sponsored workshop entitled "Tribological Limitations in Gas Turbine Engines" held on September 15-17, 1999 in Albany, New York. The impetus for the workshop came from the ASME's Research Committee on tribology whose goal is to explore new tribological research topics which may become future research opportunities. Since this subject is of current interest to other industrial and government entities the conference received cosponsorship as noted above. The conference was well attended by government, industrial, and academic participants. Topics discussed included current tribological issues in gas turbines as well as the potential impact (drawbacks and advantages) of future tribological technologies especially foil air bearings and magnetic bearings. It is hoped that this workshop report may serve as a starting point for continued discussions and activities in oil-free turbomachinery systems.DellaCorte, Chris and Pinkus, OscarGlenn Research CenterGAS TURBINES; FOIL BEARINGS; MAGNETIC BEARINGS; GAS BEARINGS; TURBOMACHINERY; TRIBOLOGY; OILS; INDUSTRIES

When it was first published some two decades ago, the original Handbook of Lubrication and Tribology stood on technology's cutting-edge as the first comprehensive reference to assist the emerging science of tribology lubrication. Later, followed by Volume II, Theory and Design and Volume III, Monitoring, Materials, Synthetic Lubricants, and Ap

Volume III extends this handbook series to cover new developments and topics in tribology that have occurred during the past decade. It includes in-depth discussions on revolutionary magnetic bearings used in demanding applications in compressors, high-speed spindles, and aerospace equipment. Extensive coverage is given to tribology developments in office machines and in magnetic storage systems for computers. Monitoring sensors are addressed in the first chapter, followed by chapters on specific monitoring techniques for automobiles, diesels, and rotating machines. One chapter is devoted to procedures used for tracking the remaining life of lubricants. Synthetic lubricants are discussed by outstanding specialists in this rapidly developing field. Synthetics are increasingly important in widely diverse areas, including compressors using the new ozone-layer-friendly refrigerants and a variety of extreme-temperature and environmentally-sensitive applications. Water- and gas-lubricated bearings are given similar attention. The contributors also develop a new, unified coverage for fatigue life of ball and roller bearings; for design and application of porous metal bearings; for self-contained lubrication, involving oil rings, disks, and wicks; and for plastic bearings. Each of these classes of bearings are used by the millions daily throughout industry. The three-volume handbook is an essential reference to tribologists and lubrication, mechanical, and automotive engineers. It is invaluable to lubricant suppliers; bearing companies; those working in the aerospace industry; and anyone concerned with machine design, machinery wear, and maintenance.

The 24th Leeds-Lyon Symposium was held in London from 4th-6th September 1997, where it was hosted by the Imperial College of Science, Technology and Medicine.The meeting addressed the topic of "Tribology for Energy Conservation" and attracted a wide range of stimulating papers and speakers. Some 150 delegates from nineteen countries attended and about sixty papers were presented in fifteen sessions. These covered the topics of lubricants, wear, friction reduction, hydrodynamics, elastohydrodynamic lubrication, surface roughness, manufacturing, component life (including condition monitoring), and automotive aspects.
