Abstract
액체로켓엔진의 질유량과 압력, 에너지의 균형을 이루게 하는 에너지 발란스 프로그램을 개발하였다. 에너지 발란스 프로그램은 액체로켓엔진 시스템의 통합 최적 설계의 기초가 된다. 액체로켓엔진을 추력실, 터보펌프, 터빈, 공급계 부품, 가스발생기, 예연소기로 나누어 모듈화 하였으며 각 모듈 프로그램을 제어하는 방식을 사용하였다. 사이클은 가스발생기 사이클과 단계식 연소 사이클을 대상으로 하였다. 모듈별로 입출력 변수 관계를 정리하여 각 사이클에 맞게 N2 다이어그램을 만들었으며, 이를 이용하여 에너지 발란스 과정을 프로그램으로 만들었다. 가스발생기 사이클은 Dieter K. Huzel과 David H. Huang이 계산한 설계 변수들과 비교하였고, 단계식 연소 사이클은 미국의 우주왕복선 메인 엔진의 데이터와 비교하였다.
