The formation of secondary vortices during the interaction of a tip vortex with a lifting surface is considered. The mechanism of formation of secondary vortices as a result of separation of the boundary layer on the lifting surface is investigated. Two variants of the mutual arrangement of the tip vortex and the lifting surface are considered. The numerical simulations are performed for the incoming flow Mach number M_∞ = 3. The numerical data are obtained on the multiprocessor hybrid supercomputer system K-60 at the CKP KIAM RAS.
