Abstract RU 2525335 C1

FIELD: aircraft engineering.

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. Tailing edge of extra aerofoil is aligned with rear edge of end plate while nose flap is located at leading edge of end plate under the level of tailing edge, sweep making 60-85 degrees. Leading edge sweep makes 60-85 degrees. Extra aerodynamic sweep of light elongation has extra sharp leading edge made at end plate inner side to make with leading edge outside end plate outer side the sweep of 76-87 degrees.
