To predict structural massof a launch vehicle more accurate at a conceptual design phase, a structural mass model was developed. The modelpredicts a launch vehicle’s structural mass, thickness, center of mass and mass moment of inertia. Load carryingstructures within in a conventional launch vehicle were modeled on a subsystem level by determining force andmoment acting on the structure during flight. The model was developed for use in launch vehicle optimizationalgorithms, and thus relies on a relative small amount of calculations to obtain structural strength of parts. Themodel supports walls made of isotropic and orthotropic material, sandwich panels, rings and stiffeners. The modelwas compared to existing models and known data from existing launch vehicles. The results did indicate a goodconvergence for determining wall thickness when compared to values found in literature.
