The paper presents the results of experimental studies of the influence of incoming external disturbances on the flow of straight wing and UAV models at different angles of attack and slip. Using the method of hot-wire anemometry, quantitative data were obtained on the structure of the flow near the surface of the model when it flows around a free stream and in the presence of incident external disturbances. Pictures of the visualization of the flow around models under stall conditionswere obtained. It was found that incident external disturbances under certain conditions can significantly change the flow structure.

外部扰动对直翼和后掠翼流动的影响

本文介绍了在不同攻角和滑移角下，传入外部扰动对直翼和无人机模型的流动影响的实验研究结果。使用热线风速计的方法，获得了模型表面附近流动结构的定量数据，当它围绕自由流流动并存在入射外部干扰时。获得了在失速条件下模型周围流动的可视化图片。研究发现，在某些条件下，入射的外部扰动可以显着改变流动结构。
