The paper discusses issues related to improving the accuracy of the calibration method of pneumometric probes in a periodically unsteady flow. In addition, the paper contains the results of numerical simulation of a flow around a cylindrical pneumatic probe, analyzes of the obtained calibration dependencies for stationary and unsteady flows, the possibility of obtaining the dependencies of static pressure by a numerical method, and also the effect of the pulse frequency on the obtained calibration characteristics of the pneumatic probe.
