RESUMO

Conditions for the separation of asymmetric flow of an ideal gas from a V-shaped wing with supersonic leading edges (conical flow) have been investigated. It has been shown analytically and numerically for high angles of attack and sideslip angles that the flow separation occurs in the region where a local pressure maximum takes place and the Ferri vortex singularity floats up. New solutions have been obtained numerically in the case of symmetric flow around a wing at a high angle of attack, when gas surge in the form of a jet takes place at the intersection point of contact discontinuities upward from the central axis. The explanation of the phenomenon is given.
