本文研究了平板上湍流边界层与人工产生的强纵向涡的相互作用，该涡实际上可能进入边界层，也可能不进入边界层。涡流是由悬挂在测试板前面的三角翼产生的，因此其配置近似于主翼后掠角为零且机身隐形的近耦合卡纳德机翼。完成了所有必要的配置和参数检查，并且对选择用于详细研究的第一个配置的数据采集和分析接近完成，在第一个配置中，涡流开始与试验板前缘下游一小段距离处的边界层合并。
The interaction of a turbulent boundary layer on a flat plate with a strong artificially generated longitudinal vortex which may or may not actually enter the boundary layer is studied. The vortices are generated by a delta wing suspended ahead of the test plate, so that the configuration is approximately that of a close coupled carnard with zero main-wing sweep and an invisible body. All necessary configuration and parametric checks are completed, and data acquisition and analysis on the first configuration chosen for detailed study, in which the vortex starts to merge with the boundary layer a short distance downstream of the leading edge of the test plate, are nearly complete.
