KARI is achieving the KSLV program according to National Space Technology Development Program. In this paper, the authors are intended to introduce the Integrated Power Plant (abb. IPP) test facility which will be constructed for the variety of tests on KSLV program. IPP test facility refers to comprehensive testing equipment for liquid rocket launch vehicle. Using this facility, KARl can verify the adaptiveness of parts and subsystems for launch vehicle and finally can qualify the system characteristics of launch vehicle doing kinds of test including hot firing test. Using this facility, KARI can simulate the vehicle launching circumstances and it make to predict the performance of launch vehicle when its flight test.

항공우주연구원에서는 KSLV용 추진기관 종합시험설비를 구축, 운영함으로써 발사체 추진기관의 각 구성품의 조립성 및 시스템 적합성을 검증하고, 연소시험을 포함한 각종 시험을 통해 구성품의 성능 확인 및 추진기관 시스템에 대한 종합적 인증(Qualification)을 하고자 한다. 아울러 발사 환경을 모사할 수 있어, 추진기관 구성품 및 시스템의 최종 환경시험이 가능할 뿐 아니라 발사시 추진기관의 성능을 예측할 수 있다. 본 논문에서는 상기 목적을 위해 구축되는 추진기관 종합시험 설비(Integrated Power Plant Test Facility)의 개념설계(Conceptual Design Analysis)과정을 통해 도출된 설계 개념을 정리하여 기술하고자 한다.

As a cryogen, LOx is a light blue, odorless, transparent liquid. Also it is not shock sensitive and does not decompose. However, it is a strong oxidizer and will vigorously support combustion. Therefore all harmful contaminants (such as grease, oil, fingerprint and organic materials) that could cause malfunctions, fires, or explosions in a oxygen environments must be completely removed prior to the introduction of oxygen. Especially, grease ingredient located inside of the LOx supply line, pipe and PHS (Pneumo-Hydraulic System) part can make drastic chemical reaction with oxygen. Therefore, to protect rapid reaction such as explosion, grease ingredient must be surely eliminated by a regular and irregular degreasing. Study on the availability, effectiveness and selection of degreasing detergents and method is described in this paper, and it will be useful for the construction and management of IPP test facility.
