FIELD: aeronautical engineering; lifting surfaces of various-purpose flying vehicle. ^ SUBSTANCE: proposed tip has swept aerodynamic surface whose lower plane is formed by smooth extension of generatrices of wing lower surface. Nose of root chord of end aerodynamic surface is located on lower contour of wing end profile at point of intersection with line of maximum thicknesses. Leading edge of end aerodynamic surface is sharp in contour and is located on one line with wing trailing edge; upper plane of end aerodynamic surface is made with smooth change at point of connection with wing. End aerodynamic surface has low aspect ratio and its sweep ranges from 60 to 85°. ^ EFFECT: improved aerodynamic property at high subsonic flight speeds. ^ 10 dwg |
