Abstract
A remote control model aircraft airfoil or wing of novel design and a related method for the construction of the airfoil or wing are disclosed in which the airfoil or wing is made of a single sheet board in a manner ensuring that the airfoil or wing is both strong and durable. A plurality of now parallel lines are scored on the interior of the sheet of material with the material being folded on the scored lines to form the airfoil or wing. In the preferred embodiment, the resulting apparatus forms a flying wing which may be used as a glider. In an alternate embodiment, a straight wing with or without polyhedral surfaces may be crafted in much the same manner.
Claims22
A method of making a model aircraft comprising:
- trimming a single flat segment of material to form a main segment of a first side of an airfoil and left and right segments of a second side of said airfoil, said main segment and said left and right segments of said airfoil each having edges which will collectively form a front edge of said airfoil, said front edge of said left segment of said airfoil being adjacent a left half of said front edge of said airfoil, said front edge of said right segment of said airfoil being adjacent a right half of said front edge of said airfoil;
- scoring a first plurality of non-parallel lines in one side of said main segment of said airfoil and said left segment of said airfoil;
- scoring a second plurality of non-parallel lines in one side of said main segment of said airfoil and said right segment of said airfoil;
- bending said main segment and said left and right segments of said airfoil along said first and second pluralities of lines to form said airfoil and to bring edges of said main segment and said left and fright segments which are unsecured together;
- and
- fastening said unsecured edges of said main segment and said left and right segments of said airfoil together to render said airfoil inflexible.
