General aircraft wing sail tip means

The present invention relates to a universal device aircraft wing sail tip, the wing is provided with a rectifying cone tip head, then on the rectifying cone is provided with a helical front sail, the sail and the sail from front to rear, the front the sail dihedral 30 °, the installation angle of -5 °; the angle of the sail amount of trans 15 °, the installation angle of -2.5 °; rear sail contra-angle 0 °, the installation angle of 0 °. The present invention is simple in structure, easy to install, fitted in an aircraft wing tip can be effectively straightened and comb wingtip vortices, having a reduced induced drag when the aircraft, to improve the aerodynamic efficiency of the sail, lift the fuselage to increase performance.
