Cradle of the New Generation Aircraft! JF-22 Ultra High Speed Wind Tunnel has passed acceptance and can reproduce flight conditions at 30 times sound speed
In the development process of various types of aircraft, a large number of simulation flight experiments are required, but it is impossible to actually frequently test fly the aircraft in the sky. Therefore, wind tunnels have emerged, which is equivalent to artificially building a "flying sky" on the ground and is an essential large-scale aerodynamic experimental device for developing aircraft...
