Introduction: How to Make the Simple SkyTomahawk Paper Airplane
Fast, long range and small, the Simple SkyTomahawk is a tiny "drone cruiser" paper airplane designed to replace the older Simple Trekker.
The Simple SkyTomahawk was designed to replace the Simple Trekker, as I decided the SkyTomahawk's tail design offered better stability for new origami aviators. To provide the best mix of simplicity and capability, I decided to mate the SkyTomahawk's airframe with the Simple Trekker's wing. In testing, this design proved to be a good performer, with excellent stability and speed. The prototype proved itself in flight testing and was approved for publication.
TAA USAF Designation: D391-3
Step 1: Materials
1 Piece of 8 by 10.5 inch graph paper
Step 2: Begin Construction
First, begin by folding your your graph paper in half (excluding three boxes on the perforated side). Once the paper has been folded appropriately, make two marks--12 full boxes apart (allow for a further box back behind the airframe). Use a ruler to make a straight line with the length of 12 boxes directly up 1 row of boxes from the two marks you just made. Then make the stabilizers, spars and counterweight as shown. To avoid confusion, one line you will cut along has been omitted from the photograph.
After the fuselage is made, take another sheet of paper that is folded in half along the lines of boxes. Mark out the wing as shown (1 box of constant chord at the root; a leading edge sweep of 1 box of chord decaying every 3 boxes outward from the constant chord box; and a trailing edge sweep of 1 box of decay along the 4 boxes of wingspan). This will complete the wings
Solid lines indicate places to cut. Dotted lines indicate fold lines.
Note: 1 box = 0.25 inches
Step 3: Making the Fuselage
Cut out your fuselage and fold its counterweights into place. Cut along the solid lines and cut off the extra vertical fin where shown. Once this is done, fold along the vertical dotted line then fold the airplane in half along the center crease once again. Fold along the dotted horizontal line then tape where indicated.
Step 4: Applying the Wings; Stapling
Cut out your Simple Tomahawk's wings and lay them beneath the fuselage. Apply tape where designated to secure them to the fuselage. Apply tape to the LERX joint and one staple where noted. This will complete the aircraft.
Step 5: Flight
As with previous SkyTomahawk variants, the Simple SkyTomahawk is a stable paper airplane and can be
handled with ease. Launches should be done at moderate to high speeds at neutral attitude. Test flights should be conducted to check the aircraft. Additional applicable surfaces include slats, flaps, flaperons, elevators, ailerons, spoilers, spoilerons and trimmable rudders. Enjoy!
