The growing interest in developing autonomous underwater vehicles (AUVs) and creating sensor networks (USNs) has led to a need for communication tools environments. For obvious reasons, wireless means of are the most desirable. However, conducting research real conditions is troublesome costly. Moreover, as hydroacoustic propagation change very significantly, even during day, assessment propose...

Abstract The accuracy of the prediction suppression efficiency triplex helical strakes for vortex-induced vibrations (VIV) is important in offshore industry risers. Towing tank tests 1:1 section model have been used study one degree freedom; however, this method requires a long time both preparation and testing. In study, scaled testing based on flume oscillating frame proposed, which measured ...

This paper deals with the resistance, towing, seakeeping, and open water propeller tests of an innovative tourist submarine model. Tests were performed in a 276 m long towing tank. As model is complex structure composed various parts attached to pressure hull, largest possible model, scale 1:5.0, was produced, considering tank depth capabilities measurement equipment. Resistance deep on surface...

Hull form selection, resistance and powering are important in designing underwater vehicle. An vehicle bare hull is based on the five parameters due to interaction between propeller hull. When they running surface condition, there will be problems likely as vessel, but main of below waterline with low freeboard. The vehicles operating high speed at a Froude Number. Therefore, wave making compon...
