F-22 White 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 on sheet 1 page 8 and opposite 8, on sheet 2, page 9 and on sheet 3 page 10. Cut parts, fold on the lines shaping pieces 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.

The F-22 is a single seat, twin engine, fifth generation, air superiority and stealth aircraft. Built by Lockheed Martin, its superb technology makes it very expensive. US laws don’t allow it to be exported outside the USA Enjoy!

Note about Glue

A suitable glue should have these features: -Accurate application. So that you can easily put a string of glue over a narrow paper tab. -Transparent. The airplane will look better if too much glue is applied and it overflows tabs' boundaries. -It should dry fast enough. Two minutes keeping a part in place should give the glue enough strenght to release the part and go for the next. -It should dry slow enough. The glue must allow during a time to shift a part to its correct position before it gets hardened. -And most important: The glue must not bend or wrinkle the paper. Before start assembling the airplane, 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 and look ugly.

Suitable glues could be “transparent liquid contact glue” usually for repairing shoes. They can be found at “Glues” section in big shopping centres or hardware stores. 4

www.PaperAircrafts.com Print pages 8, 9 and 10 in common paper A4 or Regular Letter. Using a paper with basis weight 20lb // 80gr/m2 would simplify the balancing process. Print at scale 100% to avoid parts distortion and using option ”Autorotate 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 obtain the shape of each part.

Note that you can fold 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 obtain the final piece shape.

www.PaperAircrafts.com Paste parts puting glue on the overlaping surfaces.

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

Note about printing Parts Use either letter or DIN A4 formats, preferably with basis weight 20lb // 80gr/m2 . There are four pages with parts to be printed on three sheets of paper. Page opposite 8 must be printed behind page 8, 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”. Print at 100% scale. You needn’t to print the rest of the document. View it on the screen and zoom in when needed.

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. A basis weight 20lb//80gr paper is perfect to fold and fly. As thicker is the paper as more difficult to fold and heavier the plane to fly. 7

Aerodynamic cleanness

√

X

If surfaces are bent, force the paper with your fingers trying to straighten them. The airplane may have defects, but they must be symmetrical. 28

www.PaperAircrafts.com

2

Aircraft balanced

Rest the airplane on two fingers so that the lower wing 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. Put a load in the tail.

If it falls backward, it needs more weight in the nose. Did you paste parts 17,18,15 and 28? Add some pieces of paper if needed.

3 Throwing

It is easier to throw the airplane keeping it on the sight line and impelling it on its longitudinal axis. 2.

Previously to the first flight, deflect elevator upward gently.

Correcting the flight path: Pitch

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

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

In this case the nose still needs a little more weight. Add some pieces of paper in the nose. 31

www.PaperAircrafts.com If you achieve to stabilize the glide path but it is too inclined downward… the nose may be too heavy. Try to remove part of piece 28 or put weight on the tail and reduce the elevator upward deflection.

+ 5 Correcting the flight path: direction

√

In order to correct the turn, deflect ailerons asymmetricaly like each picture shows but very gently. Deflections in the pictures are exaggerated; you would obtain the opposite effect. 32

www.PaperAircrafts.com

In case of little corrections in direction, you can use the rudders. Deflect them very gently.

Correct left turns deflecting rudders right

Correct right turns deflecting rudders left.

Slipped flight has poor glide ratio. The airplane somehow flights sideways and a little banked. Tails and wings may not be fine.

Flight path

Left slip: tails driving right, wings driving left

Right slip: Tails driving left, wings driving right

Correct left slip deflecting rudders left and ailerons driving right

Correct right slip deflecting rudders right and ailerons driving left 33

6 Adding lateral stability If the airplane flights suddenly banking to both sides, even until staying upside down, (mostly on gusty wind); adding dihedral angle, (folding wings upward a little), may improve the flight.

34

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

“Cruise”:

Deflect down the leading edge flaps a little.

The airplane will pitch down, oppose it, rising the elevators a little.

The airplane will fly more smoothly

“Approach”: Deflect down the flaps and the LE flaps a little more. Compensate the pitch down, rising the elevators if needed.

The airplane will fly slower.

“Landing”:

Deflect down the flaps significantly.

Compensate the pitch down, rising the elevators.

The airplane will fly more slowly with a shorter glide path. 35...
