摘要
研究了栅格翼的绕流特性。采用氢气泡法和丝线法在水洞和风洞中进行实验 ,显示了栅格翼的自由涡系 ,迎角 0°～ 40°范围内各网孔内的流态。还对栅格翼绕流的基本特性以及流动机理作了讨论和分析。
The characteristics of the flow about an oblique honeycombed grid fin were investigated The experiments were performed respectively in a water tunnel and wind tunnel. The free vortex system of grid fin and the flow patterns of each mesh within the angles of attack of 0°～40°range were visualized by hydrogen bubbles and silk tufts techniques. The fundamental characteristics of the flow about grid fin and the flow mechanism were discussed and analyzed.
