Consideration is given to approaches to numerical 
modeling of the distribution of temperatures and mechanical stresses 
in both thermally loaded and power elements of the nozzle blocks (NBs) 
of solid-fuel rocket engines (SFREs) that are stipulated by the structural 
features and employed materials. A typical NB design is analyzed for 
the strength of its individual units and the structure of the needed 
software is studied. Calculation examples are presented.
