摘要
In this paper, the effect of air injection on the resistance reduction of stepped planing boat by the several selected combinations of 2 longitudinal centers of gravity, 2 forms of step, 2 forms of spray strip, 5 air flow rates, is investigated experimentally. The total resistance is reduced by 25%, with air injected just ahead of the step. The required air pressure is below 0.015 Mpa.
