DYNAMIC SHAFT SEALS IN SPACE

Abstract

Investigations continued concerning techniques for sealing high speed rotating shafts under the operating condition of high temperature liquid metals and vapors, the near-vacuum environments of space, and o provide long seal life. The requirements are: the working fluid is K, the operating temperature is from melting point of K to 1400 F, the internal pressure is 15 psi and external pressure of 10 to the -6th power mm Hg, the speed of the rotating is a maximum of 36,000 rpm., and it shall have an operating life of 10,000 hr.
