Bill,
Thank you for the links, keep them coming! The great thing about information sharing are the ideas and options you probably would not have thought of.
The tip from Chip about the pressure tube is filed away in memory. Basically an aircraft static pitot system, I would never have thought of it!
Thanks
Joe

Subject: [PSUBS-MAILIST] Ambient bailing without flooding.
Date: Fri, 28 Oct 2005 18:04:28 -0400
Hi Joe and Myles.Here are some links to Kent Markham's silent runner II ambient half dry sub.I bought my minnkota from Kent and along with the motor he sent me a set of plans for both hissilent runner 2 and his delta wing ambient subs.Both plans available at psubs too.You can see the lower side door on the photos where the diver gets in and out.So you can see how the air bubble in the canopy could keep from gettingflooded but the operator could still exit the sub if he could not surface for somereason, then come back to retrieve the sub without the interior getting wet.In the silent runner 2 it would not matter if the interior got wet, but I am justshowing you this to explain the principle of how the interior could stay dry inthe ambient designs you both are contemplating and you still could bail withoutflooding the interior. Think of an upside down glass being pushed underwater.As you go deeper the water wants to rise higher in the glass but you keep it fromrising by putting more air pressure into the glass. Then if you need to bail you canswim out the bottom of the glass without having to flood the glass itself. That wayyou would not flood your engine or motors or anything else in the interior you did notwant to get wet. Just no sense in flooding the ambient. Just make sure you design anexit hole in the bottom when you build it and swim out your gopher hole if necessary.Bill.
