Abstract

This paper describes the general design procedure of cooling system for liquid rocket engine(LRE). From this design logic, cooling channels are designed and fabricated. The measured heat flux from firing test is similar to the heat flux predicted by design logic. Therefore, the proposed design procedure of cooling channel can be applied to real LRE system. Also the result of firing test indicates that combustion pressure and mixture ratio have an influence on the heat flux to be produced in combustion chamber.

본 연구에서는 액체로켓에서 널리 사용되는 냉각시스템이 장치된 실험용 액체로켓 엔진을 설계하고 제작하여 연소실험을 수행한 내용을 다루었다. 연소실험을 통해 측정한 열유속이 계산에 의한 해석결과와 유사하므로 실제로켓엔진의 설계 및 제작에 설계 프로그램을 이용할 수 있음을 확인하였다. 또한 연소실험결과 연소압과 혼합비가 추력실에서 발생하는 열유속에 미치는 영향을 고찰하였다.
