Fast, long range and aerodynamic, the Turbo Jetstream is a miniature "drone cruiser" paper airplane derived from its namesake, the Jetstream.
The Turbo Jetstream was designed to improve upon the Jetstream by fitting it with a larger wing to reduce wing loading and increase range. The Jetstream's fuselage was retained while the wing was replaced by a newer, larger design. Flight testing showed the aircraft to be a capable performer, proving itself worthy of publication.
TAA USAF Designation: D435-2
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--13 full boxes apart (allow for a further box back behind the airframe). Use a ruler to make a straight line with the length of 13 boxes directly up 1 row of boxes from the two marks you just made. Then make the stabilizers, spars and counterweight as shown.
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 6 boxes in width; leading edge sweep of 1 box of chord eliminated every 2 boxes away from the center fold and a trailing edge sweep of 1 box of chord every 6 boxes from the center fold). Then cut the wing out.
Solid lines indicate places to cut. Dotted lines indicate fold lines.
Note: 1 box = 0.25 inches
Step 3: Making the Fuselage; Stapling
Cut out your fuselage and fold the counterweight into the fuselage. Fold down the spars and landing gear, followed by the horizontal stabilizers. Apply tape where designated in the photographs. Cut away the portion of fuselage below the solid diagonal line as shown. Apply one staple where designated in the area of the counterweight folds and then tape the rear fuselage as directed in the eighth photograph.
Step 4: Applying the Wings
Cut out and unfold your Turbo Jetstream's wings. Once this is done, align the airframe with the wing and secure the wings to the spars with tape. Cutoff all excess tape and tape the leading edge of the wing to the leading edge root extension at its joint as pictured. This will complete your aircraft.
Step 5: Flight
The Turbo Jetstream cruises quickly while maintaining an excellent glide ratio; origami aviators with experience with the original Jetstream or similar Super StratoScout should be able to easily transition to and use this plane. Even to those entirely new to miniature paper airplanes, the Turbo Jetstream is a plane which one can quickly learn to work with.
Launches should be done at neutral or positive attitudes at moderate to high speeds. Test flights should be conducted to see what trim (if any) is required. Additional applicable surfaces include ailerons, elevators, flaps, air brakes and a trimmable rudder. Enjoy!
