| Abstract: | The flow field in the neighborhood of the three-dimensional intersection of two shocks of different families is investigated
when in the plane perpendicular to the line of intersection the flow velocity component is subsonic behind at least one of
the departing shocks. In the plane case these flows are not realized. The boundary of the domain of the key parameters for
which these flows are possible is determined. The characteristics of the flow field are determined when: (1) behind the departing
shocks the flow is homogeneous, and (2) the velocity vectors behind the departing and arriving shocks are parallel to a single
plane which contains the intersection line. The flow in Mach-type shock intersection in the neighborhood of the intersection
lines (triple points in the plane) is a particular case of the problem considered. It is shown that Mach-type shock intersection
is not possible when the intensity of the arriving shocks is less than for their steady-state Mach intersection in the calculation
plane.
