Abstract

Nozzleless booster is one of the applicable components for integral rocket ramjet (IRR). In order to predict nozzleless solid booster performance, the simplified theoretical analysis was applied for L/D=5, 6, 7, 9, 11, and 13. Al-HTPB and Zr-HTPB propellant with a high metal content were used to increase the hardness because of the combustion gas flow effect. It was found that the trends between the simplified theoretical analysis and experiments were similar.

무노즐 부스터는 통합형 로켓 램제트 추진기관에 적용되는 구성품 중 하나이다. 무노즐 고체 부스터의 성능을 예측하기 위해서 간단한 이론적 해석이 L/D=5, 6, 7, 9, 11, 그리고 13에 적용되었다. 연소가스 유동 효과 때문에 경도를 증가시키기 위해서 금속함량이 높은 Al-HTPB 및 Zr-HTPB 추진제가 사용되었다. 간단한 이론 해석과 시험결과 사이의 경향은 유사하게 나타났다.
