NEW W WING SHAPE FOR AIRMODELS

George ARGHIR

Abstract


The new W wing shape (half wing, with “a”half wingspan and “h” wingtip height) approximates the front seen parabola ideal wing by streight lines: line 1 touches parabola at the axis origin and is 25 % of “a”, line 2 is tangent of parabola at the wingtip and cutsthe hotizontal line at 50 % of “a”, and line 3 is tangent to parabola, cutshorizontal line at 25 % of “a” and cuts line 2 at 75 % of “a” and 50 % of “h”.Real W wing approximated very close the ideal parabolic wing. The new W wing gives more lateral and directional stability.
