环量控制舵翼性能试验研究

Experimental Investigation of Circulation Controlled Rudder

本文将航空界提出的环量控制概念应用于船舵，按NACA0015翼型截尾后连接一个半圆柱的外型，制作一种尾缘喷流的环量控制舵模型。试验表明，加入喷流后，各攻角下的升力系数都有显著增加。为了减少这种舵翼的三维效应，进一步提高舵的性能，又在模型的中间和两端分别装上了隔流板。试验结果显示，隔流板的加入，使该舵性能在不同程度上得到改善。

Results of hydrodynamic experiments n circulation controlled rudder (CCR) withlow aspecf ratio, conducted in the close circut water tunnel is given. The tested CCRmodel has NACA 0015 section but with a circular cylinder in place of the truncated tail.The test results indicate that the lift force of the rudder increases appreciably with thejet momentum. By installing end plates and guido plates on the rudder, it was found thatthere were vari us extent of improvements in rudder performance.
