Abstract
ADVANCED GAS TURBINE ENGINES WILL REQUIRE MAIN SHAFT BEARINGS TO OPERATE OVER A CONTINUOUS TEMPERATURE RANGE FROM -50 TO 500 C. THE FEASIBILITY OF A SYNERGISTIC ASSEMBLY OF LUBRICATION TECHNOLOGIES IS INVESTIGATED. THESE INCLUDE: (1) A NEWLY SYNTHESIZED HIGH TEMPERATURE FLUID BASESTOCK TO EXPAND THE ELASTOHYDRODYNAMIC (EHD) LUBRICATION RANGE, (2) THE MANUFACTURE AND MODIFICATION OF A CERAMIC AND HARD FACE COATING TO OBTAIN MICRO-FINE SURFACES FOR "ULTRA THIN EHD" LUBRICATION AND (3) THE EVALUATION OF VAPOR DEPOSIT LUBRICATION AND A "CHEMICAL CARRIER" TO TRANSITION INTO A HIGH TEMPERATURE "THERMAL DEPOSIT" LUBRICATION MODE. FEASIBILITY STUDIES ARE CONDUCTED WITH A HIGH TEMPERATURE (815 C) TRACTION TEST RIG (WA MACHINE).
