This report describes the second year's effort on a program that has as its objective the development of nitrogen gas lubricated bearings that have the best potential for stable operation at temperatures up 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 the equipment, instrumentation and experimental work. Quantitative performance data and a dimensionless map which summarizes the stable speed capability of the 360-degree hybrid bearing are provided.
