Research objective earrying out of investigations int hydrogasdynamic parameters for one-and two-phase gas flows as applied to developed systems of rocket & space technology and problems of national economy importance. Research methods-theoretical one based on using the numerical methods for solving differential equations, and experimental method with the use of laboratory large-scale equipment. This report represents the description of mathematic simulation elements and program realization for estimating nonsteady-state flows through branched pipelines and combustion chambers of control liquid-propellant rocket eugines, thermo-and gasdynamic process for solid-liquid particle heating and acceleration devices. Preliminary evaluation of parameters of process for asseleration and heating solid-liq uid particles through gas flow in technological devices is given. The estimate of on engine starting and mode entering is carried out. Effect of waves process into combustion chamber is evaluated. Test experiments on updated bench for trying out of the thermostatic systems are conducted. The developed program realization and a procedure for experimental tests can be used under today_s modernization and development of new systems in rocket & spase technology and national econonomy.
