摘要：
The supersonic pulse wind tunnel was described. The device was simple in design due to application of the standard KMU-25 valve as a commutating component. Ulconsiderable modification of the valve permitted to essentially reduce the time of valve opening and extend the pressure operating range. The installation was ease in service, compact and simply jointed with vacuum cameras of various units. The tunnel permitted to produce supersonic gaseous flow with the following parameters: static gaseous pressure in the flow - 150 torr; gaseous jet diameter - 4 cm; durability of outflow quasistationary stage - 50 ms, flow M number - 3.
