액체 질소로 윤활되는 극저온 하이브리드 저널 베어링의 성능 측정

Abstract

The current work shows the performance measurements of cryogenic hybrid journal bearings with nine square recesses for liquid rocket engines. Liquid nitrogen is used as a test fluid for cryogenic lubricant in rocket engines. The measured bearing characteristics are significant design inputs in the design procedure of bearings in cryogenic turbopumps.
