Research of Underwater Vehicle Powering Calculation

Calculations of resistance and powering are very important in floating vehicle design. Because of limitations of architecture and alignment, these calculations are more important in underwater vehicle design. This paper researches the powering calculations of an AUV . Initial describe the empirical formulas for calculations of submersible vehicle, then simulated the stream around of AUV with its propeller by CFD method to estimate the resistance and required power. Practical test and experimental work have been done for calculate of power and efficiency of the floating devices. The analysis result and experimental work have been described. Finally, the power that calculated by CFD and empirical methods is verified by experimental method and represented the amounts of error.
