摘要
本文介绍了一种展弦比为1的环量控制舵翼在零攻角下的水动力性能试验。试验模型是安装有尾缘喷流圆柱的NACA0015截尾方形舵。试验结果表明，随喷流动量系数的增加，开力系数显著上升。为减小阻力，在模型尾缘圆柱上开了一排V形槽，开槽后的模型阻力有不同程度的降低，并且喷流动量系数越大，减阻越大。开槽的另一个效果是使喷流失速推迟。
The hydrodynamic experiments of a low aspect ratio circulation controlled rudder (CCR) wasconducted in a rectangular closed-circuit water tunnel. The original model of CCR was aNACA0015 foil with a cylinder at trailing edge. The testing results show that the lift and drag coefficients increased both notably with the increase of spurt momentum coefficient. In order to increase the efficiency of this CCR, a large scale longitudinal surface grooves were cut at the cylinderof the rudder tail. Thus the drag coefficient decreased remarkably and the staIl of the CCR wasalso delayed
