Aim To study the best outer ballistic parameter matching scheme of bottom row rocket composite extended range projectile. Methods Based on the calculation of the strata-velocity and drag-coefficient strata of compound extender, the characteristics of the external trajectory are analyzed. The external trajectory simulation software is used to calculate the external trajectory of the compound extender. Results Based on the results of the external ballistic calculation, the relation between the bottom row, rocket charge and other parameters and the range of the projectile were given. And under the condition of certain total charge, Good match. Conclusion Through the study of the ballistic parameter matching scheme, it has some guidance to the design of the overall structural parameters of the bottom-row rocket composite extended range projectile
