성형작약 제트를 이용한 Ammonium DiNitramide (ADN) 단일추진제 추력기 성능 분석

Abstract

A performance analysis using CFD (Computational Fluid Dynamics) simulation was carried out for the solid propellant engine based on shaped charge jet. The purpose of this study is to find the optimal thrust efficiency geometry according to the change of propellants and nozzle shapes. In order to improve the thrust efficiency in relation to weight, the shape and weight of the engine were modified with the shaped charge principle. The thrusters of various shapes were modeled, and thrust performance was analyzed through CFD simulations. The results show that the shape of the propellants and nozzles using the shaped charge jet was the efficient thruster modeling relative to weight.
