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.
