NONPLANAR WING TIP FOR AIRPLANE WING AND WING CONTAINING SUCH TIP Russian patent published in 2014 - IPC B64C5/08 B64C3/58 B64C23/06 

FIELD: transport.

SUBSTANCE: tip (W; W1, W2) of wing (T; 10a, 10b) contains base (E1) and vertex (E2). Local dihedral angle of wing tip (W; W1, W2) is continuously increasing or decreasing from base (E1) to vertex (E2). Local sweep along rear edge (50) is continuously increasing in its propagation from wing tip (W; W1, W2) base (E1) to vertex (E2). Local sweep along front edge (60) is continuously increasing in propagation of front edge (60) from the base (E1) to the first intermediate point (61a), is continuously decreasing from the first intermediate point (61a) to the second intermediate point (62a) and continuously increasing from the second intermediate point (62a) to the area forward of vertex (E2) of wing tip (W; W1, W2). Wing contains tip.

EFFECT: improved aerodynamic characteristics.
