Wind tunnel internal flow field state detection device and method based on space three-dimensional silk thread array

The invention discloses a wind tunnel internal flow field state detection device and method based on a space three-dimensional silk thread array, and the device comprises two circular rings with the same diameter as a wind tunnel, the two circular rings are perpendicular to the axis of the wind tunnel and are placed in the wind tunnel, the two circular rings are connected through a plurality of rods, and a plurality of plastic supporting lines are connected between the two rods with the same horizontal height. And a silk thread for detecting a flow field is fixed on each supporting line. According to the invention, a reliable three-dimensional non-contact detection method can be provided for a flow field detection experiment in a wind tunnel and the like, and the method is of great significance to development of aircrafts and detection of flow fields. 本发明公开了基于空间立体丝线阵列的风洞内流场状态检测装置和方法，装置包括与风洞直径相同的两个圆环，两个圆环垂直于风洞轴线放置于风洞中，两个圆环之间由数根杆相连，相同水平高度的两个杆间连接有若干塑料支撑线，每一根支撑线上固定有用于检测流场的丝线。本发明可为风洞内流场探测实验等提供可靠的立体的非接触式检测方法，对飞行器的研
