摘要
本文所介绍的是将环量控制翼概念应用于船舵以提高船舶的操纵性的探索性试验。试验用原始模型是按NACA0015外形制做的一种小展弦比环量控制翼,试验是在循环水槽中进行的。结果表明,加入喷流后,升力显著增加。为进一步提高这种机翼的性能,我们还进行了在原始模型基础上加隔流端板、加分流板以及改变尾圆柱形状的模型试验,这些改进都在不同方面、不同程度上提高了该机翼的性能。
This paper presents experiments of hydrodynamic-ferformance of three-dimensional (low aspect ratio) circu-lation-controling airfoils (3-D CCW). The experiments were performed in the rectangulan closed-circuit water tunnel in Wuhan University of Water Transportation Engineering. The original model of 3-D CCW is an NACA0015 model with steel-made cylinder instead of cut tail. The results show that, as the jet momentum coefficient increases, the lift coefficient increases notably. In order to impprove the performance of This CCW, we installed side baffler plates at two ends of the model and splitter plates at the steel-made cylinder, and changed the shape of steelmade cylinder. The results show that, with these changes, the performance of the model is improved.
