Title

Rotordynamics Of Ultra High Speed Lightweight Compact Cryocooler

Abstract

This paper concerns the rotordynamics modeling and analysis, which is an integral part of a larger effort of a novel design, fabrication and testing of a reliable, efficient, compact and lightweight cryocooler. The cryocooler is being developed by the research team at the University of Central Florida to serve NASA's missions. Cryocoolers are the key component of zero-boil off propellant storage systems. The goal is to make a smaller and more efficient Reverse Turbo Brayton Cycle (RTBC) cyrocooler with an operational life span sufficient for Mars travel and other in-space operations. Due to the size restrictions, the internal rotating components must spin in excess of 150,000 rpm, with an optimal rate of 200,000 rpm. The design must assure critical speeds above this operational speed. A detailed model, including bearings and damping, is developed and analyzed. The "numerical" results obtained proved a "correct" design and allowed the proceeding with fabrication.
