AIRCRAFT WING TIP Russian patent published in 2013 - IPC B64C3/10 B64C5/08 

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering. Proposed wing tip has end plate with aerodynamic sweep of light elongation and sharp leading edge arranged at end plate end outer side. Aerodynamic surface trailing edge is aligned with end plate rear edge. Tip is located at end plate front edge, below rear edge while sweep make 60-85 degrees. There is lower vertical aerodynamic surface of small elongation coupled with end plate so that its leading edge coincides with leading edge of end plate aerodynamic surface. Angle between end plate aerodynamic surface and lower vertical aerodynamic surface makes 125-30 degrees.

EFFECT: higher aerodynamic efficiency, decreased fuel consumption.
