Аннотация:The results of investigations of the conical nozzle block of the hypersonic shock
aerodynamic tube (HAST) [14] of the Laboratory of Radiative Gas Dynamics of the Institute
for Problems in Mechanics RAS are presented. The efficiency of short conical nozzle is
calculated. The gas dynamic flow parameters were measured experimentally at different
distances from the nozzle exit. The design pressure values are compared with the
measurements at the nozzle outlet. Comparison of numerical calculation and experimental
results shows that the nozzle is started, successfully worked and it is possible to obtain a
uniform flow at Mach numbers M = 5...7.
