Tóm tắt báo cáo

This paper presents a method of calculating a total hydrodynamic drag coefficient for a complex-shaped underwater vehicle. The strip theory and experimental data are used to find a hydrodynamic drag coefficient of an underwater vehicle using the analytical method. A suitable hydrodynamic drag coefficient of the underwater vehicle will be found by adjusting advanced input coefficients and comparing the results of the analytical method and a result of a reliable simulation program.
