Determination of mass-power propertions for parametric range of launch vehicle modifications

Let’s consider the method allowing to solve the problem of rational distribution of Tsiolkovsky’s numbers in stages and define the appropriate mass-power proportions for the parametric range of launch vehicle modifications where the stages are shaped from the universal rocket units. The problem solution converges to the general task of non-linear programming. The method is described for a version of a two-stage launch vehicle. But it can be easily applied to the versions with a great number of stages.
