The Paper Jet Engine

With my guidance, you will create paper model jet engines for use on the mono and biplane.

Step 1: Cutout

Cut the paper at the 2 inch mark. Save the scraps for the prop and bearing.
Wrap the paper over the bottom of the marker, and tape. Mark the wide and narrow ends.
Measure the diameter of the wide end, and cut a square out of the scraps so that the length of side S = diameter of tube W

Step 2: The Paper Clip--Part A

Bend the top of the paper clip, and bend the point back out. Attach the bearing(See my monoplane and biplane instructable for detailed instructions on the bearing).

Step 3: The Prop

Puncture the center of the square with the paper clip.
Cut out tabs. Bend tabs down. Insert the point of the paper clip through the prop.

Step 4: The Paperclip--Part B

Tape the end of the paper clip so the prop doesn't fall off.
Clip the clip to the narrow end of the tube so the point is inside, and pointed towards the wide end. Look down the tube, and notice any edges of the prop touching the tube. Remove the clip and snip away slowly at the prop until it can spin freely in the tube.

Step 5: Finished!

Tape the paper clip on the outside of the tube so it is clipped on the narrow end. the paper jet is ready for attachment onto a paper airplane.

    Its not fake, he is blowing into it creating thrust, if you threw it it would spin like he shows

    Attaching these "jet engines" will only cause drag and ultimately slow down and crash any paper aircraft. The spinning of the turbines in the video file was the authors breath (if you did not know that). In conclusion, this cleverly designed contraption (this is a compliment!) is just for looks.

    Monoplane - the typical plane, with just one layer of wings. Mono means single - one. Biplane - The old fashioned planes such as in World War One, with two layers of wings. Bi means dual - two. Triplane - Three layers! Whats four...? Quadroplane? There were some wierd German designs with more than four layers (didn't work of course!)

    what the creator means is that it's mainly for use on his other instructables, if you look up his name, you'll get an instructable for monoplanes and biplanes. but sorry, he dosn't show you how to make centaplanes.

    Hell yeah, like the Heinkel Lerche.
    "The Lerche was an early coleopter design. It would take off and land sitting on its tail, flying horizontally like a conventional aircraft. The pilot would lie prone in the nose. Most remarkably, it would be powered by two counter-rotating propellers which were contained in a donut-shaped annular wing."

    there was also one I saw that looked like a rocket but had 4 shafts that spun around a central motor right below the cockpit. on the end of the shafts there would be an other motor with a prop. it could take off vertically and was meant to be a bomber escort. sorry no picture :'(

    A recent study of old bi and tri-plane aerodynamics using CFD found that they sometimes actually had a negative effect on lift because the higher pressure from the top airfoil would cancel with the lower pressure above the lower airfoil. -Just an interesting fact to take into consideration for future model designs.

    It's far from fake.  You can havae electric jets too.  It's just not a "modern" style jet engine.  Most people don't realize that there is more then one type of jet angine.  This one is all mechanical, it's called a DUCTED FAN.  Which is a type of jet engine, when done in this manner.  IT's a cool concept and pretty slick. 

    If the fan has enough power, adding a nozzle could help increase the thrust.  As would shrinking the distance between the edges of the blades and the walls of the tube.

    yes, i understand its a real engine, but does it atually create thrust? i f i but this on a paper airplane, would it make it go faster, or is it just for looks?
