The applicability of the calibration method for heat flux sensors based on anisotropic bismuth thermoelements and a heterogeneous copper-nickel structure using a reflected shock wave to determine the volt-watt coefficient is demonstrated. The coefficient obtained for a sensor based on anisotropic thermoelements is close to the stationary calibration data, and for a sensor based on a heterogeneous structure, to the results of numerical simulation. Keywords: heat flux, calibration, shock tube, shock wave, ghfs, hghfs.
