本发明涉及一种抛物线型导流翼,由不同开口方向的抛物型导流翼与放射状鳍片有机组合而成,其中,左开口导流翼与右开口导流翼形成的封闭结构,主要用于加速内部流动;左开口导流翼突出封闭结构的部分,主要用于改善左侧不利预旋;放射状鳍片用于改善不利预旋、支撑抛物线型导流翼。本发明的抛物线型导流翼,通过与流场精细配合,能够高效改变不利轴向(船舶前进方向)、周向(螺旋桨旋转方向)流动,达到显著提升节能效果目的。

    The invention relates to a parabolic flow guide wing which is formed by organically combining parabolic flow guide wings with different opening directions and radial fins, and a closed structure formed by a left opening flow guide wing and a right opening flow guide wing is mainly used for accelerating internal flow; the left opening guide wing protrudes out of the part of the closed structure and is mainly used for improving unfavorable pre-rotation on the left side; the radial fins are used for improving unfavorable prerotation and supporting the parabola type flow guide wings. According to the parabola type flow guide wing, through fine cooperation with a flow field, unfavorable axial flow (the advancing direction of a ship) and circumferential flow (the rotating direction of a propeller) can be efficiently changed, and the purpose of remarkably improving the energy-saving effect is achieved.
