Abstract : Test methods, developed during the first year of this program and described in ASD-TDR-63-264, Part I, were used to evaluate the high-temperature capabilities of candidate lubricants intended for use in the advanced gas turbine engines of the commercial supersonic transport. The candidate lubricants were evaluated in the following tests: (1) lubricant oxidationcorrosion test, (2) lubricant deposits and degradation test, and (3) gear load-carrying capacity test. In addition, preliminary tests were conducted on the 3-ball/cone fatigue tester to determine its operating capabilities and to study the mode of fatigue failures obtained with the tester. Of the nearly 40 different candidate lubricants evaluated in one or more of the high-temperature tests described, only one lubricant, a 5P4E polyphenyl ether, exhibits adequate performance up to 600 F.
