Abstract

In order to perform the scramejt engine intake ground test using the Scramjet Engine Test Facility(SETF) of the Korea Aerospace Research Institute. we introduced the test availability check procedure that is generally conducted. The design process of the newly manufactured Mach 5 nozzle for the scramjet intake test was summarized, a device for checking the core flow distribution of the nozzle was explained, and the core flow test analysis results were written. Through a series of test results, it was confirmed that the intake was located in the new Mach 5 nozzle core.

한국항공우주연구원 스크램제트 엔진 시험설비를 활용한 스크램제트 엔진 흡입구 지상 시험을 수행하기 위하여 일반적으로 진행하는 시험 가능 여부 확인 절차를 소개하였다. 스크램제트 흡입구 시험을 수행하기 위하여 새롭게 제작된 마하 5 노즐의 설계 과정을 정리하였으며, 노즐의 코어 유동 분포를 확인하기 위한 장치를 설명하고 코어 유동 시험 분석 결과를 기록하였다. 일련의 시험 결과를 통하여 흡입구가 신규 마하 5 노즐 코어에 위치하는 것을 확인하였다.
