FLYING VEHICLE LIFTING SURFACE TIP Russian patent published in 1996 - IPC

Abstract RU 2063365 C1

FIELD: aeronautical engineering. SUBSTANCE: to enhance aerodynamic efficiency of flying vehicle due to creation of additional suction force due to tip trailing vortex, trailing edge 3 of tip 1 has step 4 located at distance of (0.1-0.3) b_xip from wing leading edge at width of (0.1-0.4) b_xip, where b_xip is wing tip chord; at area of step, profile has larger relative curvature and twist angle as compared with tip profile before step. EFFECT: enhanced aerodynamic efficiency. 6 dwg
