Techniques of a Small-scaled Supersonic Air Wind Tunnel

It was detailed to introduce the basic structures,operating principles and the technical characteristic of a small-scaled supersonic wind tunnel equipment.It can complete air motive experiment under the condition where the Mach number scope is between 2 and 7.Mainly it can measure the Mach number,stagnation pressure,stagnation temperature,air flow and aerodynamic test of the supersonic speed air current;can also look into and study the shock wave,boundary layer separation and boundary layer etc the air current with the different Mach number forms in the model surface and can form continuous picture on the computer.It can widely be apply to the science research that relates aerodynamics,ammunition engineering and the aviation aerospace etc.
