Реферат: eng: We present the results of designing the contours of supersonic parts of the solid-propellant rocket motor (solid motor) nozzles with high expansion ratios with the aid of direct variational methods. A continual model is used for the motion of a two-phase polydispersed continuum with regard for processes of interaction both between the carrying gas and the particles suspended in it and between the particles of various fractions. The method of local variations is employed as a numerical method of searching for the extremum of a multivariate function. The computational results evidence a fair efficiency of the proposed approach for the optimization of such nozzles. © Nauka/Interperiodica 2006.
