FIELD: aviation.
SUBSTANCE: invention relates to aircraft engineering. Wing with an aerodynamic curtain contains main part, an aerodynamic curtain and a control system. Aerodynamic curtain is installed on trailing edge of main part of wing with possibility of delaying development of reverse flow in boundary layer as angle of attack of wing increases and is functionally connected with the control system. Total aerodynamic profile of wing is formed by profile of main part of wing in combination with profile of aerodynamic curtain. Aerodynamic curtain is made in form of sections, each of which is compensated by weight relative to axis of rotation, is pivotally mounted on trailing edge of main part of wing and is kinematically linked to the control system. Design of control system provides possibility of positioning sections of aerodynamic curtain along incoming flow with zero total hinge moment.
EFFECT: invention is aimed at improving flight safety.
