Lockheed Martin F-22 Raptor
is the United States' new air dominance fighter. The origins of
the F-22 can be traced to the early 1970s, when the U.S. Air Force
began studying concepts for replacement of its F-15 air
superiority fighter. This became a formal program when the service
requested proposals for an Advanced Tactical Fighter (ATF) in
October 1985. The F-22 is the world's first fighter to introduce
all-aspect stealth, as well as supercruise-supersonic flight
without afterburners.

How to manufacture F-22 Raptor
Download the drawing and print it on thick paper. (Refer to Material and Instrument.) Set
up your printer for thick paper.
Cut the paper according to the thick line. Start with body of
plane. Fold up as dash and dot line " _ . _ . _" , and fold down
as dash line " - - - - " . Cockpit is surrounded partly in the
body. After folding, open and cover back side of plane in paste or
glue and re-fold. Cut out the catapulting hook. Fold air intake of
engine and paste on the lower side of body. Paste nose cover at
nose of body.
Attach the wing on the body. Dihedral angle of main wings is 0
degree. Bend down (anhedral angle) horizontal tail wing at thin
line by 7 degree. This anhedral angle is not seen in real F-22,
but it is effective to avoid interference of main wings and
increase stability for paper airplane flight. Paste vertical tail
fin parts on the inner edge of horizontal tail wing (refer
figure). Vertical tail fin is inclined out by 28 degree from
vertical line. No balance weight is needed.
Adjustment
Bend front edge of main wings slightly as a bow shape to make
camber. Form washout (decrease angle of incidence at wing tip) at
the tip of main wings to avoid tip stall and increase stability.
Bend up very slightly horizontal tail wing at front of vertical
tail fin as body line for pitch adjustment. Spray paint thinly if
fly outdoor.
Rev 2.1
The shape of the air intake is closer to the actual plane.
