Development of Monopropellant Thruster for Spacecraft Propulsion System

우주추진기관용 단일추진제 추력기 연구개발

In Korea, study of monopropellant thruster have been started from 1990s by KARI (Korea Aerospace Research Institute). 5N hydrazine thruster that is a first Koreanized hydrazine thruster, have been used as flight model for several satellite. In parallel, in order to retain core technology for monopropellant thruster, catalyst and test facility development have been carried out and successfully completed. On the basis of these technology, KARI is performing development of 1N/200N hydrazine thruster and basic research of green propellant thruster.
