摘要
为了探索减少格栅翼阻力的方法和途径 ,进行了超声速M∞ =2 .5 2 1下格栅翼的边框几何形状和尺寸以及格栅翼茎厚度、格栅几何形状对格栅翼阻力特性影响的风洞实验。结果显示 ,格栅翼的边框对格栅翼的阻力影响最大 。
An investigation of the experiments of wind tunnel for grid fins is conducted by choosing different frame cross section shape and thickness and web thickness of grid fin at supersonic speed M ∞=2.521,in order to research the characteristic of grid fin drag reduction. The results show that the frame of grid fin has the greatest effect on the grid fin drag characteristics,the grid fin drag may be reduced effectually by selecting appropriate frame cross section shape and thickness of grid fin.
