FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Aerodynamic profile 12 incorporates system 10 to control boundary layer that comprises flap, flap suspension assembly, first appliance to blow air from bottom surface of aerodynamic profile 12 to change laminar airflow into turbulent airflow at positive deflection of the flap and second appliance to apply suck-off force on bottom surface 14 to preserve laminar flow at negative deflection of the flap. Method and aircraft are characterised by use of aerodynamic profile.
EFFECT: lower drag.
