The distribution of the gas temperature over the radius of a supersonic high-temperature free underexpanded jet at different distances from the plasmatron nozzle cut, as well as the distribution of the stagnation pressure, heat flux, and shock layer thickness along the length of a supersonic high-temperature blocked jet, is investigated experimentally depending on the sensor diameter. It is shown that in the calculation of the Mach number, static pressure, and thermodynamic enthalpy of the air of the underexpanded jet (near the nozzle cut), it is necessary to account for the thickness of the shock layer formed upstream of the sensor.
