Abstract : This report describes the third year's effort on a program that has as its objective the development of nitrogen gas lubricated journal and thrust bearings that have the best potential for stable operation at temperatures to 1900 F and speeds to 60,000 rpm with low flow rates. The program concentrated on attaining quantitative performance data on dynamic rotor bearing behavior. The report summarizes equipment, instrumentation, and experimental work. Quantitative performance data and a dimensionless map which summarizes the stable speed capability of the 306 degree hybrid bearing are provided as well as the summary of work on the flex pad bearing.
