Extra-ballistics Optimum Design And Experimental Results Analysis About Combined Extent Range Projectile

This text takes some type combined extent range projectile as the background, researches the extra-ballistic parameter optimization of the design in order to achieve the purpose of increasing range. this method to extend range is one of the popular measures, since the combinative using of the base bleed and rocket, projectile's flying ballistics become very complex, which lead to many factors affect the range, so it is hard for flying ballistics design during all designs.firstly this paper analyses the extra-ballistics characteristics of base bleed and rocket combined extent range projectile, establishes its mathematical model, discusses every parameters of the ballistic characteristics of optimal trajectory and the matching conditions, analyses these parameters by the immediate and statistical analysis of Taguchi method, and brings out each influencing trend of the artillery range. So the theoretical base is settled for confirming the greatest combination about extra-ballistic parameter of base bleed and rocket combined extent range projectile and it establishes optimum design method to increase range of purposes.This article uses the base bleed extra-ballistic calculation software as the foundation, takes VB prepared calculation procedures about the range to calculate. With the range flight test analysis, the optimum results illustrated that the theoretical research work has practical value and the method of these models are correct and feasible. The research works in this thesis may not only provide the scientific choosing and deciding the research project, but also will make an important role for its future development.
