FIELD: transport. ^ SUBSTANCE: set of inventions relates to aircraft engineering. Proposed system comprises a device secured to aircraft tail part to periodically rotating about the axis located at, approximately, right angle to flight direction. Said device is arranged on wing upper surface 4 and comprises stationary element 6 and first 7, 9 and second 8, 10 wing elements pivoted behind said stationary element 6 and can be spaced apart along flight direction. Method is distinguished by using aforesaid device that prevents swirling of airflow nearby outer wing in swinging about axis of rotation. ^ EFFECT: reduced turbulence in aircraft wake. ^ 5 cl, 10 dwg |
