Foil Face Seal Development

Abstract

This paper describes the development to date of a novel combination of a foil gas thrust bearing and conventional face seal secondary to produce a hybrid design. The thrust-bearing portion has demonstrated an ability to handle sea face distortion far in excess of any other gas film riding seal. Some seal leakage has been sacrificed to accomplish this. Testing of the complete seal package including the secondary seal remains to be done. This will allow determination of actual seal leakage rates. The hybrid concept has some flexibility to tailor leakage rates and distortion capability. It is expected that an optimized configuration will be tested in the AADC/GE Phase III JTDE engine.
