Eurofighter Typhoon

Ala 11 Escuadron 113 Fuerza Aerea Española Build an easy paper jet model with your hands, some scissors, two rules and some glue ! Check your handiwork skill ! Challenge a child to build it ! Assemble one as a gift for someone ! Collect the most famous jets in the world ! Once built, fly it ! Print in sheet 1 pages 7 and opposite 7, in sheet 2 page 8, in sheet 3 page 9 and in sheet 4 page 10. Cut the pieces, bend on the lines to give shape and paste with glue. The plane is balanced and should fly with minor aerodynamic adjustments. Whole process from assembly to flying is detailed in this document.

PaperAircrafts.com presents a flying paper-plane that attempts to replicate as simple as possible the famous Eurofighter decorated as Spanish Air Force Sq.113. Built by BAE Systems, EADS Germany, Alenia and EADS Spain, the Eurofighter is an air superiority, multi-role, twin engine, single or two seat, delta wing and canard configurated fighter. First planes were delivered in 2003.

Enjoy !

Note about Glue

Before start pasteing the aircraft, check your glue: Spread some glue in a sheet of paper and wait some minutes. If the paper gets wrinkled or wavy, then, that glue is not valid for paper; the aircraft would be deformed. Suitable glues could be “transparent contact glue” usually for repairing shoes.

www.PaperAircrafts.com Print pages 7, 8, 9 and 10 in common paper A4 or Regular Letter. Print at scale 100% to avoid parts distortion and using option ”Auto-rotate and center pages”. Do not “fit to page” or “shrink to page”. Cut parts over the external lines.

Fold over the lines with the help of the rules to achieve the shape of each part. Note that you can bend the paper on the lines with the help of the rules, (to the opposite side) and after it, with your fingers, on the same line, to the correct side to achieve the final piece shape. 5

X Put little amount of glue. Otherwise, the aircraft would look ugly and it would weight too much.

If the surfaces are bent, force the paper with your fingers trying to straighten them. The aircraft could have defects, but they must be symmetrical.

2 Aircraft balanced

Rest the aircraft on two fingers so that the wing’s circles get positioned just over them. If it keeps levelled and does not fall…it is balanced.

Ready to fly

If it falls forward, the nose is too heavy. Remove part or whole piece 10

If it falls backward, it needs more weight in the nose. Did you paste parts 10,11,12 and 13 ? Add part or a whole piece 10.

Correcting the flight path: Pitch

If the aircraft pitchs down going to the ground, deflect downward gently the elevators. Repeat the flight. If it keeps going down, deflect the elevators downward a little more until the aircraft went straight gliding.

If the gliding path osciles like above… the elevators may be too much deflected downward. Reduce the elevators downward deflection.

In this case the nose still needs a little more weight. Cut a triangular piece of paper and paste it in the nose

+ If you achieve to stabilize the glide path but it is too inclined downward… the nose may be too heavy. Remove part of piece 10 and reduce the elevators downward deflection.

Correcting the flight path: direction

To correct the turn, deflect the ailerons asymmetricaly like each picture shows but very gently. The deflection in the pictures is exaggerated; you would obtain the opposite efect. 21

www.PaperAircrafts.com In case of little corrections in direction, you can use the rudder. Deflect it very gently.

Correct left turns deflecting the rudder right

Correct right turns deflecting the rudder left.

5 Advanced Flight Once you have calibrated the glide path in pitch and direction, you can try different aircraft performances.

“Cruise”:

The aircraft will pitch down, oppose it, deflecting down the elevators a little.

Deflect down the LE flaps a little.

The aircraft will fly more smoothly

Note about printing Parts There are five pages with the parts to be printed on four sheets of paper. Page opposite 7 must be printed behind page 7 in order to the plane was correctly decorated. Check option “Auto-rotate and center pages” but do not “fit to page” or “shrink to page”. Pages 7, 8, 9 and 10 must be printed with 100% scale to avoid parts distortion. If you want to print the rest of pages use “fit to page” option.

If you want to build a static model (not to fly) you could print on a high quality paper in high resolution. But if you want a flying model it is better to use normal paper printed in low resolution for saving weight and avoiding wrinkling the paper with excess of ink. 23
