The mechanisms of penetration and decomposition of lateral fluid jets controlling the supersonic flow through rocket engine nozzles, processes in formation of a hollow spray of the fluid as an element controlling the supersonic flow, physical and mathematical models controlling the supersonic flow physical and mathematical models of acceleration and evaporation of fluid drops after injecting and Decomposition of lateral jets in a hollow spray are examined. Problems of experimental studies and elaboration fundamentals of studies in mechanisms of controlling processes providing a high velocity of energy release are refined and formulated. Anidealized working cycle of the detonation combustion chamber with the gas fuel, features of physical and mathematical models are analyzed. Preliminary studies on choosing the research subjects and the statement of research problems are carried out. The present state of the problem is analyzed, the tasks on improvement of the methodic support and software for analysis of processes of draining cooling fuel passages of the engine chamber in engine stopping with various parameters of drainage systems are refined.
