Abstract: The paper considers the transformation of the tip vortex and the formation of secondary vortices during its interaction with the lifting surface in a supersonic flow $(\mathrm{M}_\infty=3)$. The secondary vortices formation mechanism as a result of boundary layer separation on the lifting surface is investigated. A profiled and a flat wings are considered, as well as two variants of the relative position of the tip vortex and the lifting surface. Numerical data were obtained on the multiprocessor hybrid supercomputer system K-60 at the Common Use Center of KIAM RAS.

Keywords: secondary vortices, supersonic flow, tip vortex.
