no, erik does not mean the exploder perspective but the damage control perspective, many smaller propulsors are harder to damage then fewer big. and so on.

Rodger. I think it's a moot point with modern torpedoes. The primary shock wave produced by the underwater explosion followed by the exploding gas bubble can cause as much as 100G of acceleration from a 250 KG High Explosive warheard.

Having visited the ROKS Cheonan memorial, I don't think it really matters.

Okay Guys,
Gone are the propulsors. The aft gun director tower has been shortened to un mask the SPY. On the right are the thirty foot props of the Emma Maersk and on the left are the props on the USS George H. W. Bush. The Maersk props seem disproportionately large.

Hi David,

I think that's because triple-E props are designed to transmit the power at much lower revs for higher efficiency, I think - because they impart less change in momentum to the water, they need to impart it to much more water overall.

maersk E class: 80 MW on one propeller, 80 per propeller
nimitz class: 194 MW on 4 propellers, 48,5 per propeller

apart from the difference in running speed, here you see why the sizes are completely different.
I would suggest an propeller like the maersk E's the size of that of the nimitz. that would get you on 40+ MW per propeller, if you ship is similar in size to an nimitz that would mean you got an speed of about 28 knots. if you want to go faster, an nimitz sized powerplant and the propellers that belong to it would make sense.

the sideview diameter of the propellers tells me a lot more if they fit, btw, from the stern you can make everything you want look good or bad

Hi Ace,

You'reone of my harshest critics,but staunches teachers. Here are the starboard side stern elevations.

Okay,

So here is the maersk design scaled down to the Bush Size.



I like it.

One question I have, wouldn't you have some of the propellers turning inwards and others turning outwards to reduce the paddle wheel effect? I can't remember the exact layout for most warships but on most civilian designs the outermost/wing propellers turned inwards and the inner props/central shaft outwards.

CRP FTW!

The two starboard propellers should turn inwards, the same for port propeller's. Or to say it more simple: all propellers must turn toward center,
