Secondary Emission Technology And Dual-pulse Electronic Ignition Artillery Missiles

This dissertation focuses on the study of the propulsion method of missile/rocket by the gun. The two-stage propulsion technology and high-low launching technology are the two major methods. This dissertation mainly studies the two-stage propulsion technology.In this dissertation we make a research on the technology through simulating the process of the two-stage propulsion on the 30mm gun instead of the 120mm gun. Firstly ,we introduce the principles of the propulsion technology , the process of the propulsion technology and the central propulsion tube . The feasibility of simulating the tow-stage propulsion technology on the 30mm gun is proved by the similar gun theory. To study the process of the technology, we set up a zero-dimensional interior ballistic mathematical model and finish the charge loading condition computation. The influences of these conditions on the features of interior ballistics are studied .The variety, the size and the amount of the charge which can meet the ballistic requirements are determined. Finally, the double-pulse electronic igniting system is designed, then the principles and functions of its components are presented.
