Abstract

Multi-port HDPE and Paraffin firing tests are conducted for hybrid gas generator application of a ducted rocket in the low oxidizer mass flux range. A fuel rich gas of O/F ratio from 0.3 to 0.8, a typical O/F operating range of a ducted rocket gas generator, have been achieved with paraffin fuel implying that the hybrid system can be a potential candidate. It was also found that an almost constant O/F ratio regime exists under $35kg/m^2s$ of the oxidizer mass flux, opening a possibility for the paraffin fuel toward the VFDR gas generator application.

본 연구에서는 하이브리드 추진시스템의 덕티드 로켓용 가스발생기 적용을 위하여 낮은 산화제 유속 범위에서 HDPE multi-port(7port) 그레인 및 파라핀 그레인을 이용한 연소 시험을 수행하였다. 파라핀 연료의 경우 일반적인 덕티드 로켓용 가스발생기의 O/F비 작동조건인 0.3~0.8의 범위를 충족시켜 덕티드 로켓용 가스발생기로서의 적용가능성을 확인하였다. 산화제 유속 $35kg/m^2s$ 이하의 구간에서 산화제유속에 따른 O/F비의 변화가 일어나지 않는 구간이 존재함을 확인함으로써 VFDR 가스발생기로서의 적용가능성 또한 확인할 수 있었다.
