The utility model provides a dynamic mobile test car for testing aircraft air flow. A test platform used for carrying an aircraft to be tested is placed at the front portion of the test car, and a driving cab is placed at the back portion of the test car. The height of the test platform is not more than 700mm, and a guard bar is placed on the edge of the test platform. The front end of the test platform is a closed angle with 90 degrees and the lower portion of the front end inclines inwardly by 45 degrees. A rubber blanket with a thickness of 5mm is matched on the bottom of the test platform. The test car utilizes direct-current power to drive, a front axle of the test car is a drive axle and a back axle is a steering axle. The front axle and the back axle are both provided with steel spring plates and hydraulic vibration dampers. By utilizing the helping hand of an electric vehicle, the blowing test of the aircraft the same as that in the wind tunnel is achieved, so that the corresponding test data is acquired, thereby solving the problem that due to the pretty large compression ratio of an over-sized aircraft or an aircraft with a high aspect ratio, the aircraft body is damaged and the test in the wind tunnel is impossible.
