Introduction to Korea Space Launch Vehicle-II (Nuri)

Korea Space Launch Vehicle-II (KSLV-II) has been developed to launch 1.5 ton mass to Sun Synchronized Orbit.
KSLV-II is a three-stage rocket. The first stage is propelled by four 75 ton class liquid rocket engine of which
propellants are liquid oxygen and kerosene. One 75 ton class liquid rocket is on the second stage. The third stage
rocket generates thrust using 7 ton class liquid oxygen kerosene engine. On each flight event, the KSLV-II must
maintain its attitude with various devices. Reaction control system is a small rocket propulsion system for attitude
control of the KSLV-II. In this seminar, principle of reaction control system and development of real reaction
control system will be presented.
