Abstract: 
The problems of numerical simulation of different jet streams in space rocket engineering objects and their elements are considered. The capabilities of the computing programs and computational techniques developed at the Institute of Technical Mechanics of the N.A.S. of Ukraine are discussed. The following aspects of jet streams problems are described: interaction of subsonic and supersonic jet streams with supersonic and subsonic boundless flows, with streams in pipes or channels, including jet streams in the launcher container and around the fuel pylons of a hypersonic flight vehicle with supersonic burning combustion chamber; the computation of single and composite supersonic jets in rocket propulsion systems and their interaction with surfaces; estimation of parameters in asymmetrical separating zones behind the bottom of a rocket with a working jet.
Keywords: hypersonic flight vehicle, numerical simulation, rocket propulsion systems
