METHOD OF INCREASING AIRFOIL LIFT AND REDUCING DRAG Russian patent published in 2012 - IPC B64C21/02 B62D35/00

Abstract RU 2469911 C2

FIELD: aircraft engineering.

SUBSTANCE: air jet is directed to top surface 22 of flap 20. Portion of air in air jet is bled via air intakes 41 from airflow flowing over top surface 11 of the wing fixed part 10 located upstream and ahead of the flap. Air jet bled by suction by air intakes 41 is intensified by compressed airflow blown via channel 30 open immediately downstream of air intakes 41. Note here that combined jet including sucked air and blown jet is ejected on flap top surface 22 via outlets 44 arranged at wing fixed section rear edge. Aircraft wing allows implementing above described method.

EFFECT: increased lift, decreased drag.
