Abstract:
Testing techniques for evaluating experimental gas turbine lubricants in face-riding main shaft jet engine seals at temperatures representative of high mach aircraft have been under development. Using the RTD-1 procedure, a total of six runs were made using five lubricants. These lubricants were rated in regard to test rig life determined by seal-lubricant interaction. Additional information on deposit forming characteristics, viscosity and acid number change, seal wear, and oil consumption is reported for each lubricant evaluated. A portable instrument console and a portable test oil cart were constructed as a part of this contract. These replaced existing items and were constructed to conform with current practice at WPAFB.
