Vortex structures on close-coupled canard configurations;
在近距耦合鸭式布局中的涡系结构
On the basis of wind-tunnel force-measurement,pressure-measurement and water-tunnel flow visualization,the effect and law of canard sweeps on lift increment were studied for the canard configurations with a 50° swept delta-wing and different delta-canards on the condition of without canard-spanwise blowing and with canard-spanwise blowing.
利用低速风洞测力、测压以及水洞流动显示实验,对一组由机翼前缘后掠角为50°与不同鸭翼后掠角的三角翼构成的近耦合简化鸭式布局模型,系统研究了鸭翼后掠角在有无鸭翼展向吹气情况下该布局的增升效果及规律性。
To explore the flow field development with angle of attack on the canard configuration aircraft,a water tunnel flow visualization investigation was performed on both canard on and canard off configuration aircraft models in BUAA.
为探讨鸭式布局飞机全机流场随迎角的演变规律 ,分别对无鸭翼布局与鸭式布局两种情况于北航大水洞进行了染色液流场显示实验。
