The measuring method for projectile breech pressure measuring based on storage measurement technique is presented. The projectile breech pressure gauge is designed based on miniaturized technology,low power technology and anti-impact technology. It can be insulated with projectile in insulation can. The projectile breech pressure gauge can tolerate high pressure and high pressure in the chamber when the projectile launching,can tolerate high acceleration when penetrating, it has features of high accuracy,high reliability,easy handling. The effect of acceleration is analyzed in theory;correction method based on experimental method is put forward. In the live-fire ballistic testing,projectile breech pressure curve and chamber pressure curve at the same time is obtained. This provides data basis for analysis their relationship. The testing results show that the measuring method mentioned above is feasible,test data provide the important basis for the design of conventional weapon、projectile and fuse.
