A helicoid. The outer edge is a helix but since it is a plane, not a line, it becomes a helicoid.

I believe your are talking about a 3D figure called a Mobius strip. It is a strip of paper that has a half-turn in it that causes technically a one sided figure.
This is a simple machine called a screw.
The Twisted blade that helps a plane fly and a ship move is call a propeller.
A twisted pantyhoe.

a spiral galaxy is what you call a "kind" or classificationfor example the milky way galaxy is a spiral galaxy
The inclined plane has been utilized probably billions of times . . . especially if you call screw threads a coiled inclined plane.
A spiral galaxy has the shape of a pinwheel. Our solar system is in a spiral galaxy that we call the Milky Way.
