Abstract

Scaled model of a dual-mode ramjet engine with large backward-facing step, as a component of the rocket-based combined cycle engine, was designed. Design parameters were derived for this engine with the consideration of application for the rocket-based combined cycle engine. Design methodology was established for these design parameters. The design was partially verified through numerical study. Flow characteristics of the dual-mode ramjet engine with large backward-facing step was investigated experimentally. The design methodology for relevant design parameters established in this study was verified as feasible.

로켓 기반 복합 사이클 엔진의 구성 요소로서 큰 후향 계단을 가진 이중 모드 램젯 엔진의 축소 모델을 설계하였다. 로켓 기반 복합 사이클 엔진에 적용하기 위해 설계 단계에서 고려하여야 하는 인자를 도출하였고 이 설계 인자에 대한 설계 방법을 정립하였다. 이러한 방법을 통하여 설계한 모델에 대하여 전산유체해석과 공력 시험을 수행함으로써 설계 검증을 일부 수행하고 큰 후향 계단을 가진 이중 모드 램젯 엔진의 유동 특성을 파악하였으며 이 연구에서 정립한 주요 설계 인자에 대한 설계 방법이 타당함을 확인할 수 있었다.
