High Speed Compressor for Subcooling Propellants

Completed Technology Project

Project Description

High Speed Compressor for Subcooling Propellants
Propellant densification systems for LH2 require compression systems that develop significant head. In the past this has required multiple stages of compressors running at high speed on grease-packed ball bearings with very limited life, large heat leak and questionable rotordynamic stability. This project will utilize foil bearings with an innovative feature that will greatly increase bearing life/rotordynamic stability, drastically reduce number of stages and cost while increasing efficiency.
