FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly to flying wing-type aircraft. Flying wing small aircraft wing top surface has two vertical lengthwise keels extending from airfoil leading edge to trailing edge in symmetry about aircraft lengthwise axis. Airfoil centre confined by vertical lengthwise keels feature airfoil top surface of larger curvature than that of bottom surface to develop positive lift. Top surface at airfoil edges between vertical lengthwise keel and airfoil side edge features curvature equal to or smaller than that of bottom surface.
EFFECT: optimised aerodynamic characteristics at takeoff and landing and in cruising flight.
