AbstractThis article presents a method for estimating the endurance of an underwater vehicle, for a typical mission scenario. The calculations are based on recent measurements in a towing tank for a new configuration for an autonomous underwater vehicle (AUV). The energy consumed by the overall system is examined for (i) straight-ahead travel in calm water and in an opposing ocean current, (ii) hovering in place in the presence of a lateral current, and, (iii) vertical descent and ascent under various ballast conditions. The vehicle capability to perform several sample missions is determined. The results show how the mission endurance is constrained by the regime of ocean currents encountered.
