Cycloen Submarine

I had this idea months ago, but didn't post it. Now I'm posting it. It is about a submarine.

Think of corkscrews. Think of propellers. The limiting factor for submarines is that they must put a lot of force on that single (sometimes double for smaller) propeelor in the back. It is okay, but we can do better.

Now, here we go with the what if... part.

What if......

The prop was not just at the back? What if it was full body?

The idea...

The cycloen propeller consists of two flat metal panels twisted around the submarine, 180 degrees from each other to counter balance each other, like a corkscrew cyclone double helix, or a giant screw with the swirly bit spinning separately from the rest. The cycloen propeller is rotated easily and ingeniously (not igneously, that means volcanically). The cycloen prop is attached to rotating rings situated around the hull. The diving planes are situated before the propeller begins and after it ends, so it is able to do things that other subs can. The rudder is also situated after the prop ends.

Spinning counterweights and flywheels, along with a specially designed tail, make sure that it is the propeller that spins, and not the sub. Or an extra set of counter-rotating props would work, too. Or small props in the tail to counteract the spin, too. Or all of them together

Benefits....

Faster, as it pushes more water, easier. It could probalbly reach higher speeds than other subs. Also, since it moves more water,

Maybe a bit quieter, as this could produce less cavitation, which means more silence (I'm not a sub engineer, so I don't know for sure). Better looking, too, if you like that sort of thing.

Also, in wartime, if a torpedo was shot at it, the torpedo could hit the prop instead of the hull, so it wouldn't do as much damage. Then the sub could feign sinking so the enemy sub would think it was and not waste any mor torpedos on it.

I just like subs.
