Abstract
초소형 공중발사용 발사체를 위한 HTPB/LOX 조합의 하이브리드 모터의 적용 가능성검토와, 기초설계를 실시하였다. 설계검증을 위하여 Pegasus XL의 자료를 사용하여 설계결과를 비교하였고, 하이브리드 모터의 평균 비추력이 330sec일 때 고체추진 발사체를 대체할수 있음을 확인하였다. 초소형 공중발사체를 위한 임무를 설정하고 기초설계를 실시하였다. 설계변수인 포트개수, 초기 산화제 플럭스, 연소실 압력의 변화에 대하여 임무제한조건을 충족시킬수 있는 비추력(Isp)의 영역을 알아내었으며, 이 영역에서 최적화를 실시 할 경우 발사체 총중량을 최소화하는 하이브리드 모터를 설계할 수 있음을 확인하였다. In this paper, the feasibility study and the parametric design of hybrid motor with HTPB/LOX were conducted for micro air launch system. Design results were compared with 1st stage of Pegasus XL for verification of hybrid motor. Results showed that hybrid motor replace solid booster if Isp of hybrid motor reaches 330sec. In addition, mission analysis was established for micro air launch system, and parametric design was conducted with design variables: number of port, initial oxidizer flux, and chamber pressure. And the region of Isp was identified by parametric study which satisfied design constraints and mission analysis.
