This is the prop of the German K-130 Braunschweig class Corvette. It is supposedly the completed prop, to which I must ask: WTF?

I would love to see the physics behind that

There's no such thing as "nothing left to draw" If you can down 10 pints and draw, you're doing alright by my standards

I have only two explanation on this. because I have never seen anything like that before. and if this is a new type of propulsion system I will welcome any information one has on it.

1.

An very advance propeller. some i don't know how work.

2.

If I remember correctly it also had problems with the ship class propulsion system's. So this may be a German / Swiss solution to test the balance of the shaft and the gear unit. with the help of weights mounted on those poles that can be adjusted?

It'd be nice to see a bigger-rez picture. If those are airfoil shapes for example, it could actually be a very efficient design.

There's a larger rez floating around somewhere, but the link that image had lead to gave me a 404error. So I just save the thumbnail.

It could be a weight and balance simulator for while the screws are off in dry dock. it would let you calibrate the engine systems without risking the screws getting hit with debris.

I think it might be a "brake wheel", used for testing propulsion machinery alongside. Trouble is, I've never actually seen a picture of one.

The moments of inertia wouldn't match a modern screw, so I think RP1 is more likely to be correct than Timothy.

RP1 has a PhD in this stuff Erik, I expect him to be more likely to be correct than I am.:

Edit: Here's a bigger version:
