Abstract

In the development of propulsion system for missiles and space launch vehicles, a variety of tests are performed to ensure that it meets the design requirements. The most efficient method is to conduct high-altitude environmental simulation tests under ground conditions. In this study, the high-altitude simulation tests were performed on an ejector system with parallel-connected steam generator. Three parallel-connected steam generators generated steam about 5 kg/s, and the design points of the ejector and diffuser were verified. However, it was confirmed that various problems occurred when operating the parallel-connected steam generator using a single supply system and an integrated nozzle.

미사일 및 우주발사체의 추진시스템 개발 시 운용고도에서 설계 요구조건을 만족하는지 확인하기 위해 다양한 방법을 활용한다. 가장 효율적인 방법은 지상 조건에서 고고도 환경 모의시험을 수행하는 것이다. 본 연구에서는 병렬 연결 증기발생기가 적용된 이젝터 시스템으로 고도모의시험을 수행하였다. 3기의 병렬 연결된 증기발생기는 5 kg/s 이상의 증기를 생성하였고, 이젝터 및 디퓨저의 설계점을 검증하였다. 다만, 단일 공급시스템과 통합 노즐을 사용하여 병렬 연결 증기발생기 운용 시 다양한 문제가 발생될 수 있음을 확인하였다.
