Numerical Simulation and Experimental Study on Interior Ballistics of a Large Caliber and Short Barrel Launching Apparatus with High-low Pressure Chamber
The charge structure was designed with high-low pressure chamber launching principle according to the large caliber and super short barrel of the launching system to ensure the ignition simultaneity and burning stability.The classical interior ballistics theory was applied to set up the model in which the composite propellant charge and nozzle combustion gas flow rate were all considered.Then numerical simulation under the conditions of normal charge,supercharge and reduced charge and corresponding experime...
