Abstract: Dynamic pressure calibration technology is the key to ensure the accuracy, reliability and uniformity of the pressure test data of aerospace models. The necessity and particularity of dynamic pressure calibration are expounded. The research status of dynamic pressure calibration technology at home and abroad is summarized systematically from three aspects: step pressure calibration method, periodic pressure calibration method and pulse pressure calibration method. The existing problems at present are pointed out and the improvement measures for the future development of dynamic pressure calibration technology are put forward.The measures suggested that laser interference technology should be applied to dynamic pressure calibration，and the nation standard of dynamic pressure should be established，which consists of step pressure calibration device，sinusoidal pressure calibration device and pulse pressure calibration device.
