Some Wind Tunnel Experiments on Three-dimensional Effects,of a Small Aspect Ratio Circulation Control Wing

本文对一小展弦比（λ＝１）可控环量翼进行了风洞试验，试验结果表明，由于存在着强烈的三维效应，若不采取有效的措施对三维效应进行抑制，则小展弦比可控环量翼三维流动的升力便远远小于二维结果（包括试验与计算）。针对这种情况，本文对小展弦比可控环量民翼的三维效应的抑制做了一些初步探讨。

A small aspect ratio Circulation Control Wing (CCW, λ=1) has been studied experimentally in wind tunnel. The results show its strong three-dimensional effects. The effects must be reduced to realize the excellent high- lift characteristics of CCW used in marine engineering, where the aspect ratio of marine wings is small. Some three-dimensional wind tunnel experiments of a small aspect ratio CCW have been performed, and an effective method of reducing three-dimensional effects is discussed and recommended in this paper.
