METHOD FOR CONTROLLING BOUNDARY LAYER ON AERODYNAMIC SURFACE WITH SWEPT FRONT EDGE

摘要

FIELD: vibration equipment.;SUBSTANCE: method of controlling flow in boundary layer on aerodynamic surface with swept leading edge includes action on flow of elongated relief elements, arranged on aerodynamic surface in area of growth of longitudinal vortices of instability both at acute angle to line parallel to front edge, and parallel to front edge line. Elongated relief elements are located on laminar section of aerodynamic surface in area of increase of longitudinal vortexes of instability and aligned elongated relief elements along such directions of lines, tangent to which are parallel to swept front edge and/or lie in acute angle between line parallel to front edge, and local direction of flow at border of boundary layer.;EFFECT: invention is aimed at reduction of resistance.;1 cl, 7 dwg
