Ballistic Performance Simulation, High-speed Launch Of The Full-combustible Cartridge Case

With the development of computer technology, mathematical simulation is an important way in studying the interior ballistics of guns now. With the project background of some national defense technique of small caliber artillery, the mathematical simulation of interior ballistics of complete combustible case is carried outIn order to simulate the real situation of the interior ballistics of complete combusti -ble case, the shape and burning characteristics of complete combustible case is taken into account while establishing interior ballistic mathematical model. Based on classical interior ballistics and parallelism layers combustion laws, simplified model is established to derive interior ballistic fundamental equations of charges with complete combustible case.The numerical simulation is carried out based on the mathematical models established above. The simulation results show good agreement with experimental data. So the mathematical models and simulation codes are feasible.To keep one of the next three parameters invariable: charges, maximum bore pressure and muzzle velocity, the effects of the complete combustible cases with different thickness and burning rate modulus on interior ballistic capability are studied.This thesis will provide a reference for ballistic design of charge with complete combustible case.
