Is this similar to sailing? Where the lift generated by wind passing over the curved sail or prop blade produces more lift allowing the boat or car to go faster

Is this similar to sailing? Where the lift generated by wind passing over the curved sail or prop blade produces more lift allowing the boat or car to go faster than the wind speed.
- ehnto 5y agoYes, that's where the creator got the idea I believe. He was imagining two sails rotating around a cylinder, which it turns out, is a propeller.
- mumblemumble 5y agoYes. If I remember right, the angle of attack of the propeller blades when this thing is at speed ends up being about the same as that of the sail when the boat's on a beam reach. To extend the analogy further, I think that the wheel-and-chain mechanism ends up functioning analogously to the boat's keel.
