NEVER underestimate the power of a Sailor who served aboard a submarine.

So I'm not an engineer, what is going on here? Are you looking at the displacement or testing the hydrodynamic efficiency of this shape? I'm just guessing here as I don't know what CFD is but I'd love to know. -

To what end? Just curious?Comment

I have no idea. I would guess to see what the flow boundry profile looks like and maybe to see what the drag bucket is, which would be attrocious, I would think.Regards,

A few years ago I developed a number of thrust/speed curves. I used both a 7 foot and 4 foot Disney Nautilus.Originally posted by cdivine View Post
I don’t have the data anymore but the curve was very exponential. At speeds above 4 mph (real speed) an increasing amount of thrust is required.
The sub is not very “hydrodynamic”. In fact if anything, a piano would probably have better flow characteristics. Nonetheless 4 mph on a model submarine such as the Disney Nautilus is still impressive.Comment
