In view of the existing pressure calibration devices could not meet the requirements of pressure calibration test of built-in fuze pneumatic generator,an atmospheric calibration test equipment and method for built-in fuze pneumatic generator were proposed.By the design of the pressure chamber body of the pressure calibration device and the intracavitary structural components such as the plug,the ejector rod and the pressure spring,the sealing problem of the pressure calibration test of the built-in fuze pneumatic generator was solved.The positive and negative pressure calibration could be carried out.The experimental results showed that the linearity of pressure calibration of the installation was good,and the accuracy of the actual pressure measurement could reach more than 95%.At the same time,the device had the characteristics of simple operation,large test range and good reliability.The atmospheric pressure calibration equipment could satisfy the demands of pressure calibration test of the built-in fuze pneumatic generator.
