[0022] The implementation of this example is, figure 1 Shown is a high-speed train-tunnel dynamic model test system for aerodynamic characteristics, including an air cannon launching device 6, a train model 1, a tunnel model 2, and a guide rail 3 in the tunnel model 2.
[0023] figure 1 , 2 , 3 show that the section of the gun barrel 4 of the air cannon launching device 6 of this example is "door arch" shape, and its bottom 3 ' shape is the same as the guide rail 3 shape in the tunnel model 2, and is the same as the guide rail in the tunnel model 2. 3 are connected into an integrated structure; the section of the guide rail 3 is an "I"-shaped structure, and the middle of the bottom of the train model 1 matches the "I"-shaped structure of the guide rail 3, and the train model 1 is slidably fitted on the guide rail 3.
[0024] figure 2 It is also shown that a wheel 5 is installed between the upper surface of the "I"-shaped structure of the guide rail 3 of this example and th...
