Re: [PSUBS-MAILIST] Escape Mockup

Joe:

Haha, I?ve had every ?mad scientist? card pulled out on me.

He used a light aircraft fuselage simply for that?however, it was meant to be a focus training for submersible operations. The one he wanted to build had a manual valve which would open and allow the water to fill the sub. He used Alvin?s ?plug? type hatch, which meant that opening it against the force of a lot of water is quite a feat ? if at all humanly possible. Me and him sat down at a Starbucks together and designed a seat similar to an ejection seat, but instead was a diving pack you put on before descending. If there was an emergency, just put the mask on, fill the sub, open the hatch, and go up. He had two hatches: one on the top and one on the bottom of the sub. Both were plug types.

I am trying some ideas out on my submarine, but like Alvin, I will have strong regulations and standards. Since I?ve dedicated a lot of time in my subbing career to ROV?s, I?ve included a separate garage for an ROV to attach to. This would allow my submarine to park itself either on the floor, or what have you, while an ROV would investigate whatever target I choose.

As part of my submarine, I?m including a large server built on board because I want the camera visuals to go three ways: directly to the pilot of the submarine and the occupant?s, then on to the on-board server where it will be stored, and then sent via surfacing cable back up to the surface. Think of the server as a black box, per se, where everything we see is recorded and can be logged, versus a lot of designs that require the data [video, pics, etc] to be sent to the surface and being analyzed.

Depending on the size of my actual submarine, I?m aiming for a two person crew with a folding down jumpseat for an observer.

Great Talking!

"I think all of your ideas are marvelous!"

Joey,

Thanks for the complement but....geez, ....you need to speak to my wife! :) "Mad Scientist" is the latest term thrown my way!

If the fellow you mentioned is practicing water landing egress from light aircraft, refer him to the recommended procedure of opening the door prior to impact, as the forces are likely to warp the fuselage and jam the door shut.

A prior post regarding operating a psub beneath overhangs (manmade or otherwise) reminded me of that very same aircraft analogy. Aside from unseen entanglements, an uncontrolled ascent, (accidental weight release), or loss of buoyancy control for any reason, could cause unimaginable trouble.

When you look at Alvin's rather simple operational restrictions, you begin to see why,... and I begin to see my own operational restrictions.

The #1 reference to the "Pilot in Command"...is very familiar territory.

I think all of your ideas are marvelous!

I have heard of a fellow out by where I live who brought a large out-of-ground pool, and mounted a cross-section of an airplane on a hoist system. He would then shut the small section up, and it would be waterproof. His wife [or son, I don not know for sure] would be operating the hoist system, and would drop him or an occupant down there. Either another diver is in the pool, or manually opened, a small nozzle is opened to allow for flooding. You then have to practice putting on an oxygen system and tanks, and manually fill the mockup with water via a full until it is completely full of water, which makes it easier to open the hatch and simply swim out.

No pictures as of yet, my apologies. I was thinking that [although] that system is used for a small aircraft mockup, the same principle can be applied to a submarine mockup, etc.

Joe...Just what I was thinking. Great idea. Maybe made of fiberglass, or even rigid plastic sheet. Something to enclose a space but maybe you could "punch" through if someone panicked. Practice is a good thing. Frank D.
