FLYING VEHICLE WING AND UNDER-WING PYLON Russian patent published in 2007 - IPC B64C3/10 B64D27/18 

FIELD: aeronautical engineering.

SUBSTANCE: proposed wing has skin and under-wing pylons. Skin is made from smoothly engageable parts at positive and negative curvature of median surface. At change from side section of wing to end section, profiles of sections are made at change of angle of geometric twist of sections, maximum thickness ratio of profiles, dihedral angle of wing and relative nose radius. Magnitude of dihedral angle of wing along its semispan has maximum between side section and plane of installation of engine. Under-wing pylon has inner side wall directed to fuselage and outer side wall which are flat in larger part of first half of pylon; they are located symmetrically relative to plane of installation of engine. Side walls of pylon are bent towards fuselage in its tail section. Maximum deflection of inner side wall from plane of installation of engine at change from lower sections of pylon to upper ones reduces and its position smoothly shifts in direction opposite to flight.

EFFECT: improved aerodynamic characteristics.
