Аннотация:Hypersonic aerodynamic shock tube is used for comparison (validation) of thedeveloped computer codes for the calculation of aerothermodynamics. Experiments in vacuumchamber of hypersonic aerodynamic shock tube showed the significant boundary layer in thenozzle. An increase in the boundary layer was observed with an increase in the length of theinner surface of the nozzle. Easy method to decrease the boundary layer of the nozzle wassuggested. Areas of pressure field near hypersonic nozzle with a reduced pressure in the momentof quasi-stationary flow from the nozzle were determined experimentally.
