失速した後退翼の剥離流域中に生じる旋回流

抄録

The generation of a kind of circulatory flow in the separated-flow region of a stalled sweptback wing was noticed. Observation on the circulatory flow was made for a model airplane by using evaported-gas-oil smoke. The presence of a strong lateral outward flow was observed in the considerable range behind the trailing edge of wing-root portions. The effect of the angle of sweep back and taper ratio of a wing on the intensity and direction of the circulatory flow were also investigated.
