Abstract
To research the combustion performance of DAGQ gun propellant in the gun chamber,based on the classical interior ballistic theory, the testing system and processing method of gun propellant combustion in the gun chamber were established.The static and dynamic combustion rules and dynamic combustion performance under different temperature of DAGQ gun propellant were researched by the closed bomb combustion test and dynamic combustion performance test in chamber of gun propellants with the microwave interference method.The results show that the testing system and processing method established can well obtain the moving process of projectile in the chamber.The static and dynamic burning rate of DAGQ gun propellant have turning phenomenon.Before the turning point, the pressure exponent of static burning rate is bigger than 1, which is less than 1 after the turning point.The pressure exponent of dynamic burning rate is less than 1.In the combustion process in the chamber,the dynamic burning rate in the gun chamber is bigger than the static burning rate in closed bomb because of the effect of burning gas flow with high velocity upon the burning surface of the gun propellant, and with increasing the pressure in the gun chamber, the difference of burning rate is more and more big.关键词
