The present invention is a device installed in a cavitation tunnel and testing a surface friction drag, capable of implementing high-speed flow for model testing under high Reynolds number conditions of 106 or higher. In the friction drag test device installed in a cavitation tunnel, a flat plate having a low friction surface is placed horizontally in the cavitation tunnel, and the frictional drag acting on the low friction surface of the flat plate is transmitted to a component load cell installed in a cavitation tunnel observation unit.

    본 발명은 106 이상의 높은 레이놀즈수(Reynolds number) 조건에서의 모형 시험을 위해 고속 유동을 구현할 수 있는 캐비테이션 터널에 설치되어 표면 마찰 항력을 시험하는 장치로서, 저마찰 표면을 가지는 편평한 형태의 평판이 상기 캐비테이션 터널에 수평으로 배치되고, 상기 평판의 저마찰 표면에 작용하는 마찰 항력이 상기 캐비테이션 터널 관측부에 설치된 분력계로 전달되도록 이루어진 것을 특징으로 하는, 캐비테이션 터널에 설치된 마찰항력 시험장치를 제공할 수 있다.
