Projectile Explosion Drives Technology

This thesis discribes the research of Projectile Explosively Drive Technology mainly on theoretical analysis,numerical simulation and experimental research.In the theoretical study aspect, in a series of assumptions, simple model of Projectile Explosively Drive Device is established,Riemann Problem is introduced systematicly .On the solution of Riemann Problem , Godunov-type sheme has been set up, the results of simple calculation have directed the design of the device.In the numerical simulation aspect, by means of Changing the amount of explosives, the intuitive connection between the projectile muzzle velocity and the time has been calculated. Some of the key technologies which impact the struture of Explosively Drive Device have been studied.On the basis of theoretical analysis and numerical simulation, after having studied the action of Explosively Drive Device systematically, a Drive Device, which is small in struture and convenient in use,has been signed. The velocity over 2.6 km/s have been achieved Successfully and the projectiles have not been damaged hardly. Some typical impact phenomena have been observed and some theoretical study has been checked.The Explosively Drive Technology is a beneficial supplementary to the technology of acceleration in our country and is important to the study of acceleration impact. This thesis studies the it Preliminarily,hoping the achievements of this dissertation have use for reference and practical consulting value for researching personnel who major on Explosively Drive Technology.
