EVALUATION OF DESIGNS AND MATERIALS FOR HIGH SPEED-HIGH TEMPERATURE SHAFT SEALS FOR TURBOJET ENGINE APPLICATIONS
The demand for higher performance aircraft engines has resulted in increases in engine operating temperatures and pressures. In turn, this has necessitated the adoption of new shaft seal materials and rTefinement in shaft seal design. This development program was undertaken to develop rubbing seals that would operate for l000 hours, at 1000 deg F, and at a rubbing speed of 300,000 feet per minute. Accordingly, new materials were investigated; these materials were incorporated in seals; and their performance as seals was evaluated. In all, one hundred and sixty-three materials were screened on the basis of room temperature and 1000 deg E, dry, rubbing, wear tests and 1000-hour, 1000 deg F oxidation tests. Material combinations found to be promising were next evaluated ns seals under increased operating conditions, and eventually under conditions duplicating those existing in a jet engine. (auth)
