摘要
本文用二维激光多普勒测速仪(LDV)在低速风洞中测量了三角翼旋涡剖面的速度分布,确定了涡核位置和涡核的大小,给出了三角翼旋涡空间位置随迎角的变化。
The cross section velocitY distributions of a delta wingare measured by means of 2-dimensional LDV in low-speed wind tunnel.The trajectories and size of the vortex core are determined.The traj-ectories of the vortex core of a delta wing which vary with angles ofattack are presented.
