NASA ACES suit disconnects

[lmgill]

How do you assemble that configuration?

 

[Captain April]

I am all for accuracy but you may be doing a bit overkill, the suite connector doesn't have to function in order to be a great replica. I agree with the film adage it only needs to look like it works.

Not enough for me, overkill for others.. sure

 

[Captain April]

I have to admit that I have done overkill myself, I do enjoy reverse engineering real world items in 3D, it's part of my job as a POP display designer, I often have to recreate consumer products to use in my renderings. More power to you.

Working on the final versions, I hope

Bearing and bearing plate done

Trying out Potroclo's idea at some degree:
the hole in the tab would be for pressing down the spring loaded pin to slide the tab down and out off the locking ring

 

[lmgill]

That lock spring arrangement does not look positive enough for the type of design NASA normally wants. As for your lock button exterior, it needs bigger radius on the lock tab end and the hole end. In fact, I'd increase the radii of all your edges. Edge radii are the thing most people get wrong on these fittings (Including us). They are larger than they appear.

Yeah, those radii are PITA.
Need to check all of them, but I may left the tabs as they are.
Here you can see not as worn out tabs.

 

[lmgill]

The tabs are not "worn out", so don't think the radii need to be less on "new ones". Those worn edges are just the anodizing being rubbed off. NASA likes everything an astronaut handles, all rounded and soft.

I wonder if they are worried about a tear happening lol

 

[lmgill]

It's more about wear on things. The outer layer of a suit is not under pressure, so tearing that, while not desired, is not a safety issue as far as suit leakage. But as fabric elements get worn (as in "damaged", not "put on"), they have to be replaced, which is expensive. So rounding metal edges helps reduce this.

You are right.
I need to go over all the radii again.
The rings are pretty much done, I only need to tweak the bearing port plate and the springs for the tabs.
Also need to make some markings.

 

[antarusfree]

Little tweak of the dimensions. Markings done

 

[lmgill]

Looks good. But much larger radii on the clamp rings.

These rings?

 

[antarusfree]

Cross section

 

[lmgill]

Yes, those are the clamp rings. I have a couple of hardware blueprints and I'll look to see what the standard minimum edge break is called out.

Great
