Wind tunnel is used to the aerodynamic simulation test. The way of obtain the test data is rely on the data acquisition system. The static pressure distribution test in a low speed wind tunnel is introduced from the experimental equipment, measurement models, experimental system and experimental steps, etc. The results show that the experiment with advanced intelligent pressure scanning valve as the main measuring instruments is capable to provide experimental data reports and charts quickly, as well as to achieve high-precision, high-speed, multi-channel, high stability of the pressure data collection.
