재사용 우주발사체 액체로켓엔진용 터보펌프에 적용하기 위한 하이브리드 유체 스러스트 베어링: 정하중 특성 측정

Abstract

The current work presents a test rig for evaluation of static performance of hybrid fluid film thrust bearings for liquid rocket engine turbopumps in reusable launch vehicles. High speed electric motor drives the rotor and thrust disk while applying static loads on the water-lubricated test thrust bearing. The measured bearing characteristics are compared with predictions.
