A description of a gas turbine engine simulator, designated the AFAPL engine simulator, and a discussion of the results obtained using the simulator are presented. The AFAPL engine simulator was designed to provide a flexible test facility with the capability of closely simulating the critical temperatures and oil flow variables experienced by the lubricant in the full-scale engine. The No. 4-5 bearing compartment areas of a J57 turbine engine are used as the basic section of the simulator. The simulator is driven by a 100-hp variable-speed drive system through the accessory drive gearbox, providing simulator mainshaft speeds up to 10,000 rpm. Electrical resistance heaters are used to heat the air surrounding the oil-wetted areas within the No. 4-5 bearing compartment areas to the controlled test temperatures.
