Abstract

Physical statement of a problem about modelling gas dynamical processes in nozzles and jets of Rocket microthrusters taking into account their nonideal flows is stated. The description to the mathematical formulation of a problem received on this basis and the developed numerical algorithm of its decision are implemented in the form of a program complex. Results of approbation of the developed numerical model, showing its adequacy are stated.
