초록

배기노즐 형상변화에 따른 엔진성능특성 변화와 그에 따른 적외선 신호특성을 이해하기 위하여 마이크로 터보제트 엔진을 이용한 성능특성 및 적외선 신호 측정 연구를 수행하였다. 엔진 배기노즐은 원형노즐과 가로세로비가 서로 다른 5개의 사각형 노즐을 제작하여 실험을 진행하였다. 엔진의 추력 및 연료소모율은 배기노즐 형상에 따라 큰 차이를 나타내지는 않았다. 그러나 배기가스에서 방출되는 적외선 신호의 경우 가로세로비가 큰 사각형 노즐에서 적외선 신호가 점차 감소하는 경향을 확인하였다.

Micro turbojet engine test and infrared signal measurement were conducted to understand the characteristics of the engine performance and infrared signal with the variants of the exhaust nozzle configuration. A cone type nozzle and five rectangle type nozzles which has aspect ratio from one to five were used for the experimental work. The results show that there are not much difference between cone and rectangle nozzles of the thrust and specific fuel consumption. However infrared signal from exhaust gas become smaller as increasing aspect ratio.
