| Abstract: | To study the working principle of cylinder-open fin,the process of cylinder inflation and deflation is analyzed and the model of cylinder pressure inside gun bore is built. Through model calculations by coupled the cylinder pressure with the variation of pressure,density and temperature of the projectile,cylinder pressure model is analyzed for its solvability and a numerical method for calculating the variation of cylinder pressure and density is obtained. Simulation calculation is carried out,taking a smoothbore anti-tank projectile as an example,and the results are accurate and the applicability of this method is proved. The results provide theoretical basis for analysis of cylinder pressure of the open-style cylinder fin-stabilized device. |
