Abstract: To enhance the teaching quality of the airflow velocity measurement experiment in the engineering testing technology experiment course, this paper develops a vector velocity probe measurement module. Building upon traditional experimental teaching content, a three-dimensional vector wind speed measurement teaching project is developed. The module consists of a five-hole velocity probe, a high-precision angle-adjustment slide stage, supporting structural components, and a digital differential pressure gauge. It can accurately simulate vector wind speed fields by presetting pitch angles. The experiment employs the “semi-nulling method” measurement technique to acquire real-time information on airflow velocity magnitude and direction, which is then compared with preset parameters. Teaching practice demonstrates that this module can accurately reflect the dynamic characteristics and variation patterns of airflow vector velocity, meeting the requirements of experimental teaching. The course is conducted in a “fundamental-advanced-senior” progressive format, effectively deepening students’ understanding of vector velocity concepts and enhancing their practical skills in engineering measurement.
