AI Technical Summary
In wind tunnel testing, when the half-model is mounted on the upper wall, it is difficult to measure the attitude angle. Existing inclinometers and optical methods cannot meet the high-precision requirements, and the calibration cycle is long and the operation is complicated.
The system employs a positioning base plate and a distance measuring device, including a first connecting plate, a second connecting plate, and a distance measuring device. By measuring the distance between the second connecting plate and the leveling plane of the half-model, the attitude angle can be quickly adjusted and measured with high precision.
It achieves a wide range of measurement of attitude angles of half-models with high accuracy and simple operation, meeting the high efficiency and high precision requirements of the test site and has good engineering application value.
