%X This paper presents a calibrating method of measuring relative flow velocity, flow angle, local total and static pressure for subsonic compressible flows using seven-hole probe. Seven-hole probe (SHP) is a device that can simultaneously measure the pressure and velocity of a steady flow, especially the parameters of compressible flow. However, the costly and time-consuming calibration impedes its extensive application. Study of calibration and measurement method for compressible flow was carried out using seven-hole probe (SHP) based on the data from numerical simulation. Results show that the accuracy of calibration fitting of flow angle is about 2%, the relative value of both total pressure and static pressure are less than 3%. These results are better than experimental calibration accuracy in the same situation. In practice, this method is used to replace or guide traditional experimental calibration method, it can save a lot of calibration time and cost, so that seven-hole probe measurement for subsonic compressible flow has become simple and feasible.
