复合增程弹结构布局与最佳弹道的匹配设计

MATCHED DESIGN OF THE STRUCTURAL LAYOUT & OPTIMUM TRAJECTORY FOR A HYBRID EXTENDED RANGE PROJECTILE

将底部排气技术和火箭助推技术同时应用到同一弹丸上 ,是许多国家致力探索的一种使弹丸打得更远的新途径。本文针对三种总体结构布局形式的底排—火箭复合增程弹 ,分析了它们的结构特点和底排装置、火箭装置的工作特性 。

In many countries it is a new trend to combine the base bleed and rocket assistance together in a projectile so as to increase the projectiles range. In view of the fact that there are mainly three types of hybrid extended range projectile differing from each other in the general structural layout, their structural characteristics and the work performance of the two propellant units are analyzed. The effect of the order of functioning for the two propellant units on the performance of the trajectory and the matching conditions to obtain the theoretical optimum trajectory is discussed.
