# Knot Wing

foam strip folded into a mobius knot
 (-2) [vote for, against]

Make a flapping propellor out of a rectangle of foam folded into a mobius knot. It works great.

circle wing airplanes, making one of these O wings a mobius strip would slightly, IMO, be less efficient yet could be viewably artistic https://www.google....g&ie=utf-8&oe=utf-8

Some Propeller Fundamentals, and a blade angle calculator http://n-lemma.com/indoorrc/propcalc.htm

Seems to be many kinds of... https://www.bing.co...us+knot&FORM=HDRSC2
mobias knots. Some might be awful propellers. [popbottle, Jan 05 2017]

Pah. You're bluffing. Video or it never happened.

circle wing airplanes at [link], making one of these O wings a mobius strip would, IMO, be slightly less efficient yet could be viewably artistic. Flip the thing next to the hull and it might be almost identically efficient.

 //slightly less efficient//

[JHC], when you start getting criticism of feasibility from [beany], you know something, somehow has gone terribly wrong.

Flap it how? Spin it in a circle on one of its axes? bend it back and forth along one of its axes? I imagine the twist could serve as a screw, but the physics of various degrees of turning a propeller have been studied out the wazoo. Literally. I am on the john as we speak shitting out studies of propeller twist ratios. That was a lie. I'm actually shitting out a rehash of a tired business ethics paper because my school is not willing to pay for teachers to review original research. It's my fault though, I flunked out of a university that challenged me. Why yes, Ritalin is awesome, thanks for asking.
