FIELD: aviation; devices for change of aerodynamic characteristics of flying vehicles. SUBSTANCE: wing profile has leading edge section 2 rounded-off at definite radius. Slit 3 on under surface of leading edge section 2 is brought in communication with gas source 4. Gas jet 5 is blown through slit 3. Wing profile is located in air incoming flow 6. When gas jet 5 is blown from slit 3, sticks to surface of leading edge section 2 and flows around it from under surface of wing profile 1 to its upper surface in direction of trailing edge section of wing profile. EFFECT: enhanced efficiency of creation of suction force on wing profile irrespective of velocity of incoming air flow and angle of attack of wing profile. 2 dwg |
