RETRACTABLE TURBULENCE PROMOTER TO REDUCE STALL SPEED Russian patent published in 2016 - IPC B64C23/06 B64C9/12 

FIELD: aviation.

SUBSTANCE: method of bearing surface flight at low speeds includes deviation of bearing surface front edge high-lift system component, extending turbulence promoter movably connected to high-lift system component of front edge from slot the bearing surface and removal of turbulence promoter under bearing surface in response to movement of bearing surface front edge high-lift system component in nominal position. Extensible turbulence promoter comprises front edge high-lift system component attached to bearing surface, aerodynamic surface attached to bearing surface and sliding turbulence promoter connected to bearing surface, front edge high-lift system component or to both of them. Method of bearing surface controlling at low speeds of comprises enabling bearing surface flowing with flowing medium, lowering of front edge high-lift system component leading edge pivotally connected to bearing surface from nominal position into deflected position; opening of several retractable turbulators through slots in first bearing surface in response to lowering of deflected leading edge high-lift system component. Extending turbulence promoters are made with possibility of their closure under high-lift system component rear edge while front edge high-lift system component is in nominal position.

EFFECT: group of inventions is aimed at high efficiency of bearing surface operation at low speed.
