Have any of you guys looked into Project Egress with Adam Savage and the Smithsonian?
The Smithsonian gathered all the drawings to the parts that make up the hatch on the Apollo capsule. One man rendered all the drawings in Fusion360 CAD software. Adam Savage blew all of the drawings out to 44 different makers and asked them to build the parts out of the materials of their choosing. He has collected the parts and will be assembling the hatch on July 18th at the Smithsonian.

It's been fun watching the builds on YouTube. I follow some of the makers and have spent time with four of them (Blondihacks, OxToolCo, NYC CNC, and Jimmy Diresta). It's awesome that their work will be on display at the Smithsonian.

Adam Savage will document the assembly and no doubt the other makers will too.

Wasn't aware of it but sounds interesting.
That mechanism is fascinating; I assume that's the redesign after the Apollo 1 tragedy?

Yes, it is the amazingly complex new hatch.
That thing is a pretty impressive piece.

no wonder space stuff costs so much

Not like no one else already had a tested and well proven quick acting hatch design in use in thousands of applications that couldn't have been easily adapted to work on Apollo.

Well, I don't pretend to be smarter than the Apollo engineers. But I'm thinking a submarine hatch would be colossally heavy and use completely different materials than something that would be flown into space. When you are dealing with space travel every gram counts.

And vacuum sealing is different I am sure too.

An elderly friend worked on the Apollo design and construction. He was an Thermodynamic Engineer and his expertise was thermal protection of the capsule. I asked him once about what was involved and he replied "do you want the short or long version", I opted for the short, 2 hours later..
It was amazing the amount of drive and desire to succeed these guys possess.

Pretty sure I said there was a proven design that could be adapted not used as is.

It also has to be airtight, not vacuum tight. You want to keep the air in and forces working to let it out are opposite than if you were trying to maintain a vacuum instead. You want to place the door so that the pressure helps seal it.

It was amazing..BUT it was a totally different era in this country. It was a time where people still desired to work together for a great common goal, mandated by a forward
thinking, and inspirational President, who btw, never got to see NASA's fruits of their labor 50 years ago, this coming Saturday.

Its a 2- piece unit redesigned from a 3 piece used during the fatal Apollo 1 fire. New regulations for the design were put in place - it had to open in 3 seconds and all 3 fully suited astronauts to exit in 30 seconds max. secondary requirements: 1 hand operation from either side, push opan and pull close from the inside, a pressure dump valve, a backup latching system, max 20 pounds of force to operate it.

Its rocket science after all biggrin


Here's the original technical memorandum of the design proceedings in case anyone is curious

I like the concept. It's too bad Adam Savage is a total [censored].
