Fast, long range and versatile, the Turbo UltraVulcan is an improved variant of the UltraVulcan paper airplane, featuring redesigned wings for better performance and handling at high speeds and greater rigidity.
The Turbo UltraVulcan was developed to replace its basis, the UltraVulcan, in mid-June 2014. The aircraft features no changes in planform, but the structure of the aircraft is altered slightly when compared to its predecessor. The design period for the aircraft was short due to this high amount of commonality, and testing progressed quickly. After proving itself capable, the Turbo UltraVulcan was soon cleared for publication and allotted an instructable.
TAA USAF Designation: F292-14
Step 1: Materials
1 Piece of 8.5 by 11 inch Paper
Scissors (additional surfaces only)
Step 2: Length, Airfoil and Nose Folding
Fold your paper in half length-wise. Then pull the paper down so that the crease stretches from the fold at the front you just made and the corner of the paper on the other side. Repeat on the other side. Once this is completed, pull the overhanging paper back above the center crease made earlier. Fold the airfoil over themselves, then back into themselves as shown. Fold the edges of these sections down over the center crease as shown, then pull the triangular tip of the nose back over them. After this is done, open the nose fold as shown, then make the folds as
pictured. Tuck these folds into themselves, then into the nose flap as you fold it back down again.
Step 3: Nose, Canard, Wing and Winglet Folding
Begin this step by pulling the nose backward until the leading edge of the nose touches the trailing edge of the wing. Make a mark 1 inch in from this fold. Then reverse the fold up to this mark and make a crease as shown. Unfold this new crease, then pull the wingtips inward as shown. Once they are folded pull the nose forward once again. When this is done, fold the fuselage in half along the center crease. Fold down the canards whilst keeping their leading edges aligned with the nose to maintain an angle of incidence of zero degrees. Make marks 1 inch from the center crease and 1 inch from the wingtip along the trailing edge of the wing. Following this, fold down the wings at the mark you made previously. Align the trailing edges of the wings with that of the fuselage to keep the angle of incidence at zero degrees. After this is finished, fold the wingtips down at the marks you made previously.
Step 4: Taping
Apply tape to the nose above and below the canard, as well as to the dorsal LERX-wing joint. Then apply tape to the rear of the fuselage and over the wing root near the trailing edge. Once this has been done, apply tape to the ventral LERX joint and canard folds to secure them to the fuselage. This will complete your Turbo UltraVulcan.
Step 5: Flight
Like the UltraVulcan, the Turbo UltraVulcan is a very capable, fast paper airplane. The Turbo UltraVulcan should be launched at a neutral or positive attitude at a moderate to high speed. Additional applicable surfaces include flaps, elevators, ailerons, slats, flaperons, elevons, rudders, air brakes, canard trim and an "electronic warfare" tail. Enjoy!
