Re: [PSUBS-MAILIST] Sitting High



Patrick,

Take another look, "Proteus" is a bit more than a rendering....she's alive and your best bet for ideas for what you are considering.

If I recall correctly, she has a dry cabin for the Queen to sit comfy while the Emir sits out front with his buddies in their dive gear! (Being sarcastic as this is the obvious market for the thing, she's was built in Dubai after all). I believe the cabin is ambient.

But, the design is just what you seek, tremendous reserve surfaced buoyancy, shallow draft, with a clever way of disguising a relatively small submersible volume in a big, fast running surface package. Somewhere, I saw a cutaway diagram of her.....very cleverly done!

Ah, yes, I had seen that rendering before.
Similar idea but with less above deck cabin and 1 ATM

Has anyone looked into ppherical conning towers by the way?

Patrick,

Tricky, but doable so long as the design takes into account the usual stability considerations, ...ie metacentric height, center of buoyancy, cg, and the changes of same during the transition. Those hydrofoils did double duty as ballast.

Take a close look at Proteus at Exomos.com

I had considered hydrofoils. If it has been done then it is obviously viable. But I am still wondering if one could simply make larger ballast tanks and add more positive buoyancy to get more of the sub out of the water.

I have been toying with this on the back burner of my mind and in my doodles.

Also, the AUV on the orignal XXX did the hydrofoil thing if you remember... I think it was named Ahab.

Has anyone explored design options that would allow a psub to sit high on the surface?

I think it would be interesting to try to build a sub that could ride high and drive on the surfece in a boat-like manner.

Any opinions/input?
