ARROW-SHAPED WING Russian patent published in 1995 - IPC

Abstract RU 2028250 C1

FIELD: aviation engineering. SUBSTANCE: arrow-shaped wing is made with lengthening of λ, narrowing of 3 - 4, arrow-shapeness of c_1/4. Wing is mounted on fuselage at wedging angle of ϕ_wed.. Wing airborne profile is made with positive relative curvature, mean value of which is determined by f_m, maximum value - f_max = 1.2 - 4 % and mounted at wedging angle of ϕ_wed.. In the case mean curvature of wing airborne profile is connected with wedging angle by ratio df_m/dϕ_wed. EFFECT: increased aerodynamic quality. 7 dwg
