Lockheed Martin F-35C (X-35C)

X-35(F-35) is one of the Concept Demonstration Aircraft of JSF(Joint Strike Fighter) developed by Lockheed Martin Aeronautics Company. The Joint Strike Fighter (JSF) Program is the Department of Defense's focal point for defining affordable next generation strike aircraft weapon systems for the Navy, Air Force, Marines, and US allies. The focus of the program is affordability -- reducing the development cost, production cost, and cost of ownership of the JSF family of aircraft. X-35A (conventional takeoff and landing (CTOL) version ) took off at Oct. 24 2000 on it's first flight. The X-35C (carrier variant (CV)) is designed to achieve superior carrier-suitable handling qualities within a highly common family of JSF airplanes. X-35C took the first flight at Dec. 16 2000. This paper aircraft is designed on the figure at Lockheed Martin A. C. web site, but it has some difference from X-35C of tested now in detail. Real X-35 has powerful engine and computer controlled stability. So it is not the best shape for paper glider performance, but this paper plane is flying well and stably when carefully adjusted. I think this paper aircraft is the first flying papermodel of X-35 in the world (at least on the web). Enjoy flight of near future aircraft.

Congratulations!  Lockheed Martin X-35 is selected for System Development and Demonstration (SDD) phase at Oct. 26 2001.
Update Rev 1.2 X-35 is now enumerated as the F-35. The Navy's F-35C version of the plane is a carrier-based strike fighter. (For your reference, at the test of X-35, X-35C is the carrier version.)

How to manufacture JSF F-35B

Download the drawing and print it on thick paper. (Refer to Material and Instrument.) Set up your printer for thick paper. Basic structure of paper airplane is similar to F/A-18.
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.
Dihedral angle of main wings is 0 degree or slight. Bend down (anhedral angle) horizontal tail wing at thin line by 7 degree. This anhedral angle is not seen in real F-35, 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 photo). Vertical tail fin is inclined out by 25 degree from vertical line. Paste wing on the body. Paste nose cover at nose of body. Cut out the catapulting hook. No balance weight is needed.

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. Bend up slightly rear of the outer part of horizontal tail wing. Spray paint thinly if fly outdoor.
