Abstract

The propellants used in the gas generator of the ducted rocket are fuel-rich propellants, which contain an excessive amount of metal fuel and a small amount of oxidizing agent compared to general solid rocket propellants. In this paper, boron powder and MgAl(Magnesium-Aluminium alloy) were applied to produce fuel-rich propellants. The optimum formulation was determined by characterizing these metal fuel-rich propellants. Analysis of combustion products in the gas generators confirmed that the fuel-rich propellants containing fine boron powder itself instead of boron-bead could be useful in gas generators.

덕티드 로켓의 가스발생기에 사용되는 추진제는 연료과농 추진제로서, 일반적인 고체 로켓 추진제에 비하여 과량의 금속연료와 소량의 산화제를 포함한다. 본 논문에서는 연료과농 추진제를 제조하기 위하여 보론 분말과 MgAl(Magnesium-Aluminium Alloy)를 적용하였다. 이 금속연료를 적용한 추진제의 특성을 분석하였고, 이를 통하여 최적의 조성을 연구하였다. 추진제의 연소생성물 분석을 통하여 보론 비드가 아닌 미립의 보론 분말로도 가스발생기용 연료과농 추진제가 가능함을 확인하였다.
