Device mounting position of an engine control unit in a vehicle is apt to move from passenger room compartment to engine room, as more system functions are integrated into an engine control unit. This trend brings much benefit to car manufacturers on cost- & performance-effective engine room layout design and wiring harness, but also burdens to engine cotrol unit manufactureres with more harsh environmental requirements, like higher operating temperature range and severer vibration condition. The first challenge of engine control unit mounting on air-filter box in engine room compartment is a motive of huge tasks of the operating temperature range definition by many of modeling, simulation and measurements in a vehicle.

본 논문은 수중 추진기관으로 소형 액체로켓연소기를 적용하고 이를 시험 평가할 이동형 시험 장치를 설계, 제작하여 가압식으로 추진제를 공급하는 장치를 검증하기 위해 모사유체인 물을 사용하여 수류실험을 통해 안정적으로 작동하는 것을 확인하였다. 향후 설비 보완을 통하여 성능을 향상 시키고, 소형 제품의 다양한 시험 장치로 적용 할 것이다. This study aspire to apply small-sized LPRE(Liquid-Propellant Rocket Engine) as Underwater Thrust System, and to design and develop PTE(Portable Test Equipment) so as to examine the thrust system. PTE aims at supplying the propellant to the system with pressurization. In order to verify the performance of PTE, Spilling test was implemented with water whose characteristic is similar to taht of propellant in LPRE. The result from the test showed that the PTE follows designed requirements with stable performance. This research can be a potential source to further Test Equipment both for the improvement of performance and the application to diverse small-sized test devices.
