Abstract
A folded paper airplane formed of a blank of sheet material having a downfold line extending along an axis of the sheet, a pair of transverse cuts near a rear edge and forming a tail piece, a pair of fuselage forming upfold lines extending from the midpoints of segments of the forward edge to a point adjacent the intersection of the downfold line and the transverse cuts, a pair of cockpit forming downfold lines extending from the midpoints, a pair of set of at least two successive upfold lines extending from the same midpoints, and a pair of wing forming downfold lines extending from the leading edges of the resulting wing surfaces near the cockpit to terminate at the other distal ends of the transverse cuts.
Claims10
A folded paper airplane comprising:
- a blank of sheet material with a forward edge and a rear edge and having a downfold line extending centrally along an axis of the sheet material from said forward to said rear edge;
- a pair of transverse cuts spaced from the rear edge of the blank for forming a tailpiece, said transverse cuts each having one end terminating at the downfold line and the other terminating at a respective upper edge forming a fuselage;
- a pair of fuselage forming upfold lines each extending from adjacent a point of the transverse cut intersecting the downfold line to said forward edge at a respective point generally midway between the downfold line and a respective outer extremity of the blank;
- a pair of cockpit forming downfold lines each extending from a respective said point generally midway of the forward edge to a cockpit area, and generally bisecting an angle formed by the associated fuselage upfold line and the forward edge;
- a pair of sets of lines, each set comprising at least two successive upfold lines each extending also from a respective said point generally midway of the forward edge outwardly to an outer extremity of the blank and each set generally trisecting the angle between the associated fuselage forming upfold line and the forward edge of the blank;
- and
- a pair of wing forming downfold lines each extending from the respective leading edge of a resulting wing surface to the other termination of the respective transverse cut.

- a pair of transverse cuts spaced from the rear edge of the blank for forming a tailpiece and extending from the downfold line, said transverse cuts each having one end terminating at the downfold line and the other end at a respective edge forming a fuselage;
- a pair of fuselage forming upfold lines each extending from adjacent the one end of respective said transverse cut to the forward edge at a point generally midway between the downfold line and a respective outer extremity of the blank;
- a pair of cockpit forming fold lines each extending from a respective said point generally midway of the forward edge to a cockpit area, and generally bisecting an angle formed by the associated fuselage upfold lines and the forward edge so that the cockpit forming fold lines are folded upon themselves to one side of the airplane so forming the cockpit;
- a pair of sets of lines, each set having at least two successive upfold lines extending also from a respective said point generally midway of the forward edge outwardly to a respective wing edge and each set generally trisecting an angle between the associated fuselage forming upfold line and a forward edge of the blank;
- and
- a pair of wing forming downfold lines each extending from the resepctive leading edge of a resulting wing surface to the other end termination of the respective transverse cut.
