초록

A method and apparatus for boundary layer control by sucking air off the vortex chambers established in the trailing-edge portion of an aircraft aerodynamic surface. The rate of air bleed is controlled first by increasing it until the boundary layer is attached to the airstreamed surface, then by decreasing the rate of air bleed until the pressure in the trailing-edge aircraft portion starts decreasing. The aircraft equipped with the boundary layer control system, including a number of vortex chambers accommodating streamlined bodies and communicating, t...

A method for controlling the boundary layer on a rear airfoil surface of an aircraft comprising the steps of: providing vortex chambers within the rear airfoil surface, each vortex chamber including a streamlined body disposed therein; sucking air from the chambers; forming bound vortex flows within the chambers and around the streamlined bodies under the effect of a pressure gradient effective in an external airflow; and controlling a rate of air suction from the chambers to minimize energy consumption for maintaining a non-separated airflow over the re...
