摘要
本文研究了 2种重心位置、2种断阶方式、5种喷气流量对断阶滑行艇气层减阻的影响 ,取得了总阻力减少 2 5 %的效果。阻力减少的主要原因在于喷气时形成的空穴所引起的浸湿面积的减少。
The effect of air injection on the resistance reduction of a stepped planing craft experimentally investigated. The special cases of two longitudinal centers of gravity, two forms of steps and five air flow rates were examined. The total resistance is the reduced by 25%. It was found that the main factor of resistance reduction is the reduction of wetted surface area due to the formation of air cavity.
