摘要:

火箭发动机整体结构及其部件的质量、质心位置和转动惯量的计算是火箭发动机及导弹的计算机辅助设计和优化问题中的重要组成部分。为此研制成功一种基于标准几何型体的位置、尺寸、方向和材料密度的交互式的火箭发动机结构质量特性计算软件ＭＣＭ，给出了这些标准几何型体质量特性的精确计算公式。

Abstract:

The calculation of masses,centers of mass and moments of inertia of whole structure and components of rocket engines is a very important part of CAD and optimization of rocket engines and missiles. A interactive structural mass properties calculation software MCM of rocket engines was developed on the basis of standard geometrical shapes whose dimensions, locations, orientations and densities of the materials were specified. In this paper the exact mass properties calculation formulas of the standard geometrical shapes are given.
