An analytical research program was conducted to determine the influence of 12 lubricant properties and characteristics over a wide range of values on the design and performance of three advanced turbine engines, Pratt and Whitney Aircrafts J58, JTF22 and ST9. The lubricant traits investigated were hot spot stability, bulk oil stability and autoignition temperatures gear load vapor pressure low-temperature pumpability long or acceptable bearing life DN number thermal conductivity specific heat specific gravity and kinematic viscosity. If a lubricant having prescribed values of these properties and characteristics could be developed, significant improvements in turbine engine design and performance can be theoretically achieved. Three types of analyses were conducted to accomplish the program objective heat transfer, design and performance. Author
