In article is considered the problem of round stream cross input of in supersonic stream. This task has important applied value, concerning ensuring overall performance of aircraft engines - including with the truncated take off and landing, deck aircraft planes so forth. Authors are presented mathematical problem definition, proved its formalization for modeling. Modeling was carried out in number - with use of averaged by Reynolds Navier-Stokes's equations for perfect gas. In article are described used sampling in spatial-time area. Authors are investigated characteristics of a flow by the main stream at В«virtual obstacleВ», created by a cross input of additional stream. Results are visualized by means of В«fields of currentsВ» pictures and compared with the available experimental data. Received results of computer modeling for distribution of speed fields qualitatively coordinated with known experimental data.
