Self-oscillation flow regime is observed in region between longitudinally streamlined co-axial rotation bodies without external disturbances. A second order modification of Godunov’s method is used. It’s determined conditions of self-oscillation origin. Grid effects, shock wave structures is analyzed at self-oscillation and steady regimes for slowly increased stream velocity from M = 2 to 7. It’s imitated flow in indicated region at inclusion of rocket engine of second step for problem of rocket steps separating.
