Nakamura Lock?• The “Nakamura Lock” is a type of paper

airplane that is named after the Japanese origami artist who designed it.

• Using the Nakamura Lock folding method gives a paper airplane better weight distribution, allows for more control when flying, and uses an origami technique to keep the plane folded tightly throughout use.

Step 11. Fold a sheet of paper in half lengthwise. Unfold so that the crease is 'valley' side up.

Step 22. Fold the top corners down to the center fold.

Step 33. Fold the tip down.

Step 44. Fold about one inch of the tip up; unfold.

Step 55. Fold the top corners down to the center fold so that the corners meet above the fold in the tip. (Note that the top—the nose of the plane—should be blunt.)

Step 66. Fold the tip up. This is the Nakamura lock.

Step 77. Fold the entire plane in half so that the tip is on the outside.

Step 88. Fold the wings down.

Step 99. Make flaps at the back of the wings by bending them up or down.

Step 1010. Name and decorate your Nakamura Lock plane!

Questions:What is providing your airplane’s thrust?Your hand gives the paper airplane its initial thrust.

Why does your plane eventually crash?It does not have airfoil shaped wings, a jet engine or a propeller so its lift and thrust are overcome by drag and gravity.
