MODELING OF THE MECHANISM OF DECREASING THE HYDRODYNAMIC DRAG OF BODIES BY THE SURFACE RUNNING WAVE METHODS. M. Aul'chenko UDC 532.533 We explore the possibility of radically decreasing the hydrodynamic drag by changing the external flow so that the boundary layer is replaced by some flow with a small velocity gradient Institute of Theoretical and Applied Mechanics of the Siberian Branch of the Russian Academy of Sciences, 4/1, Institutskaya Str., Novosibirsk, 630090, Russia; email: email@example.com.
