Abstract

한국항공우주연구원에서는 현재 대한민국 독자적인 기술의 한국형발사체를 개발하고 있다. 따라서 한국형발사체의 추진기관에 적합한 새로운 발사대시스템의 개발이 요구된다. 한국형발사체는 엔진 추력, 단 구성, 추진기관 배관 및 구성품 규격 등이 나로호와는 확연히 변화되었기에 이에 적절히 대응되는 발사대시스템의 연료공급설비가 구축되어야 한다. 한국항공우주연구원에서는 발사대시스템의 상세설계를 통하여 예비설계 결과를 바탕으로 보다 구체적인 공급라인 구성과 구성품의 규격을 설계하였고, 충전개념을 결정하였다. 또한 케로신 공급운용 및 사전작업에 필요한 계획을 수립하였고 이에 따른 운용알고리즘을 구성하였다. Korea Aerospace Research Institute(KARI) has been developing a new launch vehicle Korea Space Launch Vehicle-II(KSLV-II) with their own technology. Thus, it is required a new launch complex that corresponds to a new propulsion system of launch vehicle. Because widely changing of KSLV-II comparing with KSLV-I such as thrust of engine system, composition of vehicle staging, pneumo-hydraulic scheme of propulsion system, it is important to establishing appropriate ground support equipments for fuel(kerosene) filling. In this critical design process, specific supply line and specification of components are designed and the concept of kerosene filling is determined based on results of preliminary design. Also, plans of supply operation and prerequisite are established and operation algorithms are formed.
