RE: [PSUBS-MAILIST] Submarine motors

When you say "deballasted" do you mean a situation where the MBTs are flooded and for whatever reason you cannot blow them? The buoyancy of the sub in that condition is normally zero. So any little bit of buoyancy will raise you, but what you'd really need is enough buoyancy to lift the coning tower clear of the water to open the hatch. In the case of a K-250, on account of the acrylic dome you will need more than in a sub with a flatter hatch. I'd have to work out some basic numbers, but off the top of my head I'd say about 150 lbs should do it for the K-250.

I'm actually in Chicago, but in 3 months I'll be moving back to Southern Cali. (somewhere between Lancaster/Palmdale and Bakersfield). I have alot of design concepts for almost every stage of my sub's production kickin around in my head, in various forms of dissaray, and some things out on the computer, but currently im spending every spare minute trying to learn how to use SolidWorks 2004 so that I can put something together that's more finite and...um...solid? Lol.

The submarine escape simulator sounds really interesting..

I'd like feedback from everyone on a project I'm working on. Its a highly portable, compartmentalized, flexible, custom, adjustable (more adjectives!!!!) system for diver assisted submarine recovery in a condition of full ballasting loss, and takes into consideration the possibility of not being able to release the manual drop weight.

I'm a certified and well practiced deep diver and have been (breifly) down to 220 feet on normal air.   So i'm comfortable with depths that some people might not be comfy trying to escape unnasisted from.   Anyhow, I've contacted a couple salvage companies, and even gotten OEM pricelists in order to put my system together.   If I can get a working iteration of it before the conference I'd like to try it on someone's "artificially stricken" sub if we have time.   It is designed not only to raise the sub to the surface completely standalone of the sub's own ballasting system, but in a controlled manner and also, to provide enough freeboard at the surface for safe evacuation and sub stability.

What I need from you all....
1) A rough idea of how many pounds of positive buoyancy would be required to raise your stricken sub. Note: im not looking for the dry weight of your sub, rather the um..."wet" weight, your buoyancy displacement when fully deballasted including your dropweight.
2) If you think this is stupid or not... tell me.   I've already got it all figured out, have already begun purchasing supplies.
