AERIAL VEHICLE WING Russian patent published in 2018 - IPC B64C3/10 

FIELD: aviation.

SUBSTANCE: aerial vehicle wing consists of a center section and consoles, centroplane and cantilevers made with elongation λ=7-11, narrowing η=3-4.5 and sweep χ=28-35°. The front and back edges of the wing at the top view are rectilinear. The rear edge is made with the strake. There is a smooth rounding along the trailing edge in the section of 30-50% of the span of the wing. The profile of the side section has an increased area in the forebody at a value of 20-50% relative to the wing profile. The value of the radii of noses of the aircraft wing profile and the wing profile, referred to the local chord, r_n.≥1.5%. The maximum profile thickness in the section is 40-60% of the profile chord, and the thickness of the tail part in the section of 70% chord is increased to values from c≥8.7% of the chord. The average line of profiles with a long concave section in the front part of the profile on the section from the profile nose and up to 60% of the profile chord. The bending in the tail section of the profile with the values of the maximum ordinate of the mid line e_ch.k.max==1÷2%. The upper surface with a long section of small curvature at the section of the 15-75% of the profile chord, determined by the relation e_d.g./e_d.g.max≥0.75, and the position of the maximum ordinate of the upper surface near 40-50% of the profile chord.

EFFECT: increased aerodynamic quality.
