APPLIED RESEARCH ON A HERMETICALLY-SEALED DRIVE COUPLING FOR SPACE POWER TRANSMISSION

Abstract

A one to one speed ratio hermetically sealed coupling for a 15 KW, 24,000 rpm unit is to be developed and the problems encountered in scaling the unit from 15 KW to 3 KW and 3000 KW are to be evaluated. The design requirements provide for power transmission through a continuous boundary with a device having a 90%ASSIFIED REPORT DESCRIPTORS: *Liquid metals, *Transmissions, *Auxiliary power plants, *Hydraulic seals, *Vapors, Hydraulic fluids, Sodium, Rubidium.A one to one speed ratio hermetically sealed coupling for a 15 KW, 24,000 rpm unit is to be developed and the problems encountered in scaling the unit from 15 KW to ver-all efficiency and 10,000 hours of maintenance-free design life. Operating conditions will be 20 to 40 psi pressure differential, 1000 F potassium or rubidium vapor on one side of the boundary, and 1/100,000 mm Hg vacuum at the same temperature on the opposite side. Both a deformable membrane and a magnetic coupling will be evaluated experimentally. One of the two devices will be selected for a 1000 hour endurance test. (Author)
