摘要
StateLaboratoryofHydrodynamicsofChina本文通过2种重心位置、2种断阶方式、2种防溅条形式、5种喷气流量的选择组合 ,研究了在断级滑行艇上气层减阻的实施途径及效果。断阶稍前处喷气能减少25 %的总阻力 ,而所需气压仅为0.015MPa。
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 0.015Mpa.
