In order to study the aerodynamic experimental methods of the high-speed and small model projectiles based on the basic structure and the experimental principle of the MAF wind tunnel. Data acquisition system hardware of high-speed and large data was designed, and the test and data processing software was designed according to aerodynamic formula. Take the some model of projectile for example, aerodynamic experimental parameters were collected, and were compared with the results of the FD-04 wind tunnel under the same conditions. It shows that the experimental methods and testing technology can be used for practical engineer-ing applications.
