Intro: How to Make the Beagle Paper Airplane
Fast, long range and aerodynamic, the Beagle is a "drone-cruiser" paper airplane loosely modeled after the Ilyushin Il-28 "Beagle" jet aircraft of the late 1940s. The Beagle is meant to supplant the StratoCruiser series.
Development of the Beagle began in late August as I felt a new straight wing cruiser design was called for. Inspired by the shape and success of the Il-28, I decided to configure the new design similar to the early Cold War era aircraft. After completing the prototype, flight testing showed the aircraft capable and it was approved for publication shortly thereafter.
TAA USAF Designation: D360-1
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. 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 rudder and counterweight as shown. Follow the photograph markings. Then, mark out the wing spars and skids. One box forward of the trailing edge of the vertical stabilizer, make a solid horizontal line 2 boxes in length as shown (this will later become the slot through which the horizontal stabilizers pass). Also, draw the diagonal line along the bottom of the fuselage.
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 (3 boxes of chord at the root, by 5 boxes in width, with a leading edge sweep of 0.50 boxes of chord eliminated every 4 boxes away from the constant chord portion of the wing and a trailing edge sweep of 1.5 boxes of chord every 5 boxes from the root). Then cut the wing out. Measure 2 boxes along the crease, measure two boxes upwards from one mark and make another point. Then draw a diagonal line connecting this new mark to the one further away. From the mark you just made, measure one box further away from the one now connected to the line and make a mark. Sketch a line between this mark and the other mark along the crease. Then cut the horizontal stabilizers out.
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 the counterweight into itself as shown. Then unfold the fuselage and cut the right vertical stabilizer off. Then restore the fold. Fold the fuselage forward at the vertical dotted line on the vertical stabilizer. Once you have made the cut along the solid line, unfold. Once this is done, fold down the spars and skids. Then apply tape where designated. Now cut along the diagonal line at the keel of the airframe.
Step 4: Applying the Wings and the Horizontal Stabilizers; Stapling
Cut out your wings and lay them out flat. Align the fuselage over top so the spars align with the wing as shown. Then apply tape. Cut off any excess. Flip the aircraft over and apply tape to the leading edge of the wing above the leading edge root extensions. Once you have finished with the wings, cut out your horizontal stabilizers and slide them through the slit in the fuselage you made earlier. When through, fold them up and apply tape to the underside; then fold down. Then apply one staple in the area of the counterweight. This will have completed your aircraft.
Step 5: Flight
The Beagle is very aerodynamically clean paper airplane, so launches are more similar to those of drone fighters. Launches should be at neutral attitudes at medium to high speed. Launches can be done at a positive attitude, but launch speed should be increased (range may be reduced). Elevator trim may need adjustment, so test flights are highly recommended. Additional applicable surfaces include slats, flaps, flaperons, elevators, ailerons, spoilers, spoilerons, air brakes and a trimmable rudder. Enjoy!
