FIELD: aircraft engineering. ^ SUBSTANCE: invention relates to aircraft engineering. Aircraft wing tip features sweepback of leading edge with wing lower surface formed by smooth continuation of wing lower surface generatrix. Leading edge of wing tip end is made straight and sharp with sweepback of 70 to 85 at the point of intersection of nonlinear leading edge of wing tip with continuation of the line of maximum wing thickness. Profiles chords parallel to wing symmetry plane form lower surface. Transition from wing with profile blunt nose to sharp one of wing tip rear end, over lower surface, is made smooth. Upper surface of wing tip is formed by continuation of wing upper surface to smoothly terminate at sharp leading edge. ^ EFFECT: improved aerodynamic properties. ^ 8 dwg |
