Introduction: How to Make the Strike UltraVulcan Paper Airplane
Fast, long range and small, the Strike UltraVulcan is an improved variant of the Simple UltraVulcan with structural refinements made to the wings to improve sturdiness and high speed handling. Like its predecessor, the Strike UltraVulcan is an airplane which new origami aviators should be able to transition to easily after using something like the docile SkyCub.
The Strike UltraVulcan was developed to improve the already respectable Simple UltraVulcan's performance and to enhance its capabilities. While its contemporaries were upgraded in 2014, the Simple UltraVulcan itself had not been. After two years, I decided it was time to refit the plane to allow it better performance. In addition, as I have several other new aircraft in development currently, the modest changes seen by the Strike UltraVulcan made its design quick and smooth. Flight testing confirmed that the aircraft was as reliable and easy to work with as its basis and the Strike UltraVulcan was cleared for publication on that basis.
TAA USAF Designation: F292-26
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 1.5 inches 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. 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. 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 where designated in the photographs to complete your Strike UltraVulcan.
Step 5: Flight
The Strike UltraVulcan flies very much the same as the SkyCub and other Vulcan variants which origami aviators may be accustomed to. The aircraft should be launched at a neutral or positive attitude at moderate to high speed. Additional applicable surfaces include elevators, ailerons, elevons, rudders, air brakes and an "electronic warfare" tail. Enjoy!
