Manta형 무인잠수정의 부가물 형상에 따른 동유체력 특성에 관한 연구

A Study on Hydrodynamic Force Characteristics of Manta-type Unmanned Undersea Vehicle with the Parameter of Appendage Shape

Manta형 무인잠수정(MUUTV)을 대상으로 회류수조에서의 모형실험을 통해 동일한 통체 모형 에 대해 형상이 서로 다른 부가물을 부착했을 때의 동유체력 특성을 실험적으로 검토하였으며， 동유체력 측정 결과를 이론계산치와 비교하였다. 아울러 이를 바탕으로 운동안정성을 검토하여 최적의 부가물 형상 결정의 이론적 근거를 확립하였다.

The influence of different appendage shape on the characteristics of hydrodynamic forces on Manta-type Unmanned Undersea Test Vehicle(MUUTV) was discussed experimentally. Fuselage only MUUTV model and two types of MUUTV model with different appendage geometries were considered as the subject of discussion. Oblique tow experiment was carried out in circulating water channel with three MUUTV models. A point of difference in hydrodynamic force characteristics among three models was indicated Furthermore, the línear hydrodynamic derivatives obtained from model experiment were compared with theoretical calculation results from slender body theory. added mass theory and etc. Based on the hydrodynamic force characteristics, motion stability of two types of MUUTV model with different appendage geometries was compared each other. Through the above analysis, the more suitable shape of appendage geometry was made clear.
