[PSUBS-MAILIST] Titan submersible missing at Titanic site

Fri Jun 30 11:05:23 EDT 2023

 According to an article I found the viewport diameter was 53cm which I believe was the outside dimension.  Based upon a video I found with Rush putting his hand up to the inside viewport I would estimate the inside diameter closer to 300mm.  The seat appears conical however the viewport had a convex outside surface.  Hard to say if that means it was just a regular spherical segment with conical seats or a conical viewport with a convex exterior surface.

I check out some pictures and based on a given length of 6500mm 

I come to the following rough figures: 

Diameter hull                                   1600 mm

Diameter front porthole outside         700 mm

Diameter front porthole inside            466 mm 

(these diameters indicate that the porthole could be original designed as entrance..)

Now idear about the thickness of the acrylic 

- but will check out PHSME about standard flange angles tonight.

For me it looks like the biggest diameter porthole used in that deep. 

Has somebody here inner and outer diameter and the thickness?

 The pictures of Titan that I see in water show 16 bolts holding the retaining ring in place.  See attached photo.  Jon   On Thursday, June 29, 2023 at 11:49:18 AM EDT, MerlinSub at t-online.de via Personal_Submersibles <personal_submersibles at psubs.org> wrote:  
I have seen a video how they make the carbon cylinder and can imagine that the boat imploded in longitudinal direction. 

Create a massive shock wave with push the window out (not in). As I saw in another video the window was hold by only 4 bolts outside. 

All titan parts in the video seems undamaged.
