The functionality of the more complete validation of the developed CDF is being expanded for “Hypersonic aerodynamic shock tube” laboratory facilities. Models of triple semi-wedge with sharp edge and blunt edges were tested. The regions of the high pressure close to the blunted edge of the model are revealed. In the upper model, the greatest pressure was detected on the front face and in the middle region of the flat channel. The experimental graphs of the pressure distribution on the upper and lower surfaces of the model are compared with numerical simulations at limited distances from the nozzle section.
