Research on the Internal Relationship Between Dynamic and Static Combustion Laws of Propellant for a Large-caliber Artillery

Abstract In this paper, according to the closed bomb test results of the same formula and different batches of propellant, the static combustion law of the propellant is obtained. Combined with the results of the artillery firing test, the dynamic combustion law of the propellant is obtained through...

Summary:Abstract In this paper, according to the closed bomb test results of the same formula and different batches of propellant, the static combustion law of the propellant is obtained. Combined with the results of the artillery firing test, the dynamic combustion law of the propellant is obtained through the internal ballistic simulation fitting. The relationship between the static and dynamic combustion laws of the same formula and different batches of propellants is obtained. Using the research results of this paper, for the new batch of propellant, the dynamic combustion law of the new batch of propellant can be determined according to the closed bomb test results. Combined with the internal relationship between the dynamic combustion law and the static combustion law in this paper, the internal ballistic performance prediction accuracy can be improved.
