Abstract
Investigations (mainly those performed by the authors) of air blowing through a perforated section on a body of revolution with a large aspect ratio in an axisymmetric incompressible flow are summarized. Result of numerical and experimental studies of the flow properties, efficiency of the turbulent boundary layer control and prospects of using it for a body of revolution at small subsonic velocities equivalent to the take-off and landing regimes for a modern subsonic cargo aircraft are analyzed.
