RE: [PSUBS-MAILIST] Deep Flight Challengers Interior

Brent,

Give it up please. There is a metal to metal surface for sealing with the O- or square-rings in between. You don’t want to seal glass or acrylic in a dynamic seal for deep depths (you don’t want to for glass at shallow depths either). Your port or dome is mounted in a metal ring. If you look closely at your image you can discern that.

The Navy doesn’t have a chamber large enough for that, they certify big stuff out in the ocean for deep depths.

Subject: [PSUBS-MAILIST] Deep Flight Challengers Interior

Greetings Subbers,

I've been looking for a picture showing the interior of the full ocean depth, 37,000 fsw designed sub, called the Deep Flight Challenger. I found a very interesting one. The dome looks to be severely fractured and held together with duck tape. The dome even looks like it might be made of glass. Perhaps they tested it in the US Navy's pressure chamber and it didn't go well.

Also note the double O-ring grands on the hatch land.... ;)'

I've gotten a fair amount of flack for wanting to use double O-rings for sealing my hatch against the hatch land.
