Liquid-monopropellant Thrusters for the 3-axis Attitude Control of Space Launch Vehicles -Part 2: A Practical Application of Flight-axes/Attitude Control Thrusters to the Space Launch Vehicle and Their Design Development Localization
우주발사체 3축 자세제어용 단일액체추진제 추력기 -Part 2: 비행축/자세제어용 추력기의 우주발사체 적용과 국내 설계개발
Abstract
A practical application of flight-axes/attitude control thrusters to the space launch vehicle and their design development localization are investigated and analyzed. Hydrazine thrusters are mostly used in a final stage of space launch vehicles on account of its higher specific impulse and reliability necessary for the precise attitude control attaining the orbit insertion with higher accuracy.
비행축/자세제어용 단일추진제 추력기의 우주발사체 적용과 국내 설계개발 현황을 조사/분석하였다. 탑재체의 정확한 궤도투입을 위하여 정밀한 자세제어가 요구되는 발사체 최종 단은 대부분 비추력 성능이 우수하고 높은 신뢰도 확보가 가능한 단일추진제 하이드라진 추력기시스템을 장착한다.
