High Seed Compressor for Propellant Densification

Completed Technology Project

Project Description

High Seed Compressor for Propellant Densification
Propellant densification systems particularly for H2 require compression systems developing very large amounts of head. Development of this head requires multiple stages of compressors running at high speed. In the past these compressors have run on grease-packed ball bearings with very limited life. This project will utilize special foil bearings in place of the ball bearings and not only greatly increase bearing life but also permit even higher speed operation which will reduce the number of compression stages and increase system efficiency.
