已研制出一个计算机程序,供快速进行弹道式再入弹头的参数设计之用。它能定出一个(或是一类)弹头,使它们在一组给定的设计约束条件内,达到最小重量。本文介绍了使用这个程序的具体技术及计算结果。输入数据包括:弹头的性能特征参数、弹头构架的特征参数、弹头内部组装要求、弹头重量及几何方面的约束条件。输出数据描绘出满足上述输入约束条件的最终弹头。输出数据中包括弹头的重量和重心、弹头构架的确定、以及弹头内部组装安排。此外,还提供出初始再入条件下和弹着点条件下的重量、重心、弹头的几何外形、静稳定裕度和弹道系数。本程序对设计先进弹头特别有用,目为它能很快地定出满足初始设计要求的那种弹头。
A computer program has been developed for rapid parameterization of ballistic reentry warheads. It can assign a (or a class of) warheads to a minimum weight within a given set of design constraints. This article describes the specific techniques and calculations for using this program. Input data include: warhead performance characteristics parameters, warhead structure parameters, warhead internal assembly requirements, warhead weight and geometric constraints. The output data depicts the final warhead that satisfies the above input constraints. The output data includes the weight and center of gravity of the warhead, the determination of the warhead structure, and the internal assembly of the warhead. In addition, the weight, center of gravity, warhead geometry, static stability margin, and ballistic coefficient under initial reentries and blast conditions are also provided. This procedure is particularly useful for designing advanced warheads as it can quickly determine the type of warhead that meets the initial design requirements.
