  • Hanwha Corporation Daejeon Plant have developed apogee Kick Motor of KSLV-I that is the first among nation space launch vehicle for five years from 2003. Now, we are joining in KSLV-II(Korea Space Launch Vehicle-II) project and developing Pyro starter which is turbo pump for the first start-up of liquid propulsion supply.

  • Thus paper summarizes the procedures to develop the downscaled payload kick motor for KSR-III by KARI. Filament winding-a well-known method of manufacturing composite motor case - is adopted to reduce structural weight. Netting and lamination theories are used to determine adequate winding thickness under required internal pressure. Dome shapes are designed considering feasible winding patterns and easiness of mandrel manufacturing. T-800 carbon fiber and Novolac type resin are selected for weight-reduction. The separate mandrels are disassembled and removed after filament winding. The manufacturing process of real payload kick motor is developed from the design experience of downscaled ones.

  • KSLV-1 2nd stage Kick Motor Nozzle was exposed to high temperature and pressure during the firing. Under the high pressure environment, Kick Motor Nozzle hydro-pressure test was done for verifying the structural safety of the nozzle. The differences with the KM hydro-pressure test [1] are that the real immerged heat resistance material is assembled and the throat heat resistance material is similar with the real one. The hydro-pressure tests were done for the two times of the 125 % of MEOP (975 psi) and the 153 % of the MEOP.
