FIELD: aviation.
SUBSTANCE: device for control of boundary layer on aircraft air foil consists of actuator (1) made of installed one on another from bottom to top of lower lid, shaped plate, compressed air bypass manifold, distribution of rectangular plate, collector releasing compressed air and upper rectangular cover, air intake (8) with pipeline (9). On air foil (10) there is hole. Lower cover is made in form of rectangular plate with holes for air passage, located at one side of plate. On shaped plate 3 there are holes for air passage. On longer axis of shaped plate groove is made, in which pendulum of pressure and discharge of compressed air chamber is made. There are drives supported by adjustable stops. Upper cover is made in form of rectangular plate with hole located above compressed air outlet header channel.
EFFECT: invention is aimed at improvement of aerodynamics of aircraft by creating robust system of vortexes.
