*The methodology for mathematical modeling which makes it possible to perform calcula-*

*tions and design of liquid-propellant rocket engine combustion chambers, minimizing the*

*number of bench tests, has been proposed in this article. Nowadays the numerous fire*

*tests are the basic methods to test the strength of the combustion chambers. By combining*

*a number of software packages (ANSYS, pSeven) the developed methodology enables us*

*not only to perform a checking calculation but to design an optimal structure as well. We*

*describe a step-by-step sequence of actions. Moreover, we give some recommendations*

*for a calculation of a LPRE combustion chamber on several operating modes in terms of*

*low-cycle fatigue. The proposed methodology has been approved while designing the*

*11D58MF cruise engine.*

*Keywords:*

*mathematical modeling, finite-element method, substructure, cyclic symmetry,*

*anisotropy coefficients, optimization, mode of deformation, nozzle, combustion chamber,*

*liquid-propellant rocket engine, cooling channels.*
