The submarine designers had the same issue and it also created noise to help their enemy hunt them, so they made propellors with more vanes so it could turn slower but generate the same torque and some surrounded them in an enclosure to drive the water entering the vortex faster. Strange ship builders looking for fuel efficiency and not speed don't consider this

@GrahamWalters3 жыл бұрын
A ship is recognisable by the noise it's propellor makes, no two are the same, it's called a ships signature, and submarines use it to indentify hostile ships
@allyourcode3 жыл бұрын
IIRC, the US Navy has figured out how to shape propeller blades to significantly reduce cavitation. This helps keeps submarines undetected. When subs are out of water (before launch), they cover the props to prevent people from copying their winning design. Science for the win.
