To solve the problem that it is difficult to accurately measure the gas temperature in the gun bore because of the harsh testing environment,based on microwave interferometer and pressure testing system,and combined with the calculation theory of the propellant formula performance and the interior ballistic performance,a method for estimating transient temperature of gas in bore was established based on the measured parameters,and the tests were conducted.The results show that the maximum gas temperature in bore is about 2631.8 K,the gas temperature decreases rapidly with the projectile movement,and the gas temperature in bore drops to 1 858.4 K when the projectile exits the muzzle.With this method,the change law of gas temperature in bore with time can be obtained effectively,which provides a new mean for the research on low-ablation propellants and charges.
