FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering. Aircraft wing incorporates main surface and auxiliary surface arranged on the main surface; auxiliary surface is made as a plate fixed equidistantly to the main surface by means of supports oriented parallel to aircraft axis. Rear edge of auxiliary surface spreads to the rear edge of the main surface. Front edge of auxiliary surface is arranged at distance of 0.2-0.29 of its chord from the main surface tip. Every support is made as a solid wall of height equal to 0.001-0.01 of main surface chord and arranged between them at distance equal to 0.05-0.5 of chord.
EFFECT: enhancement of wing bearing capacity.
