Flows in the channels of solid-fuel charges with cross 
sections having different views in plan and flows in the prenozzle 
volume and the nozzle unit of a solid-fuel rocket engine have been 
simulated on the basis of the STAR-CD suite for different types of 
charges and different designs of the input part of the engine nozzle. 
The influence of the compressibility, turbulence, geometric factors, 
and flow rate on the distributions of gasdynamic parameters in the 
working region of the engine has been investigated.
