Abstract

본 연구는 재생냉각 시스템 설계를 위한 설계절차를 확립하고, 프로그램을 개발하는 것이다. 재생냉각 시스템 개발을 위한 설계변수를 도출하기 위해서 물을 냉각제로 하는 냉각 시스템을 설계절차에 맞추어 설계하였다. 물을 냉각제로 하는 <TEX>$250kg_{f}$</TEX>급 엔진을 이용한 연소시험을 통해서 제안된 예측결과와 실험결과를 비교하였고, 비교적 일치함을 보였다. 이와 같이 검증된 설계 프로그램이 케로신을 냉각제로 하는 재생냉각 시스템에 적용 가능함을 확인하였다. 본 연구를 통해 얻은 기초 자료와 관계식은 실제 액체로켓엔진 설계에 직접 사용 가능할 것이다. The purpose of the study was to establish the design procedure and develop the program for designing regenerative cooling system. To obtain the design parameter necessary for the realization of regenerative cooling system, water-cooled regenerative cooling system was designed from suggested procedure. To compare experimental results with a present method of analytically predicting the heat transfer loads, <TEX>$250kg_{f}$</TEX> experimental LRE with water-cooled regenerative cooling system was investigated. Based on the investigation, the good correction between the predicted and measured data was verified. Developed design program can be used to designing Kerosene- cooled regenerative cooling system. The basic experimental data and correlations obtained in this study for 250kgf experimental LRE with water-cooled regenerative cooling system can be directly applicable to the real LRE.
