Skylab 1973 rebuild

[Urwumpe]

Do you have that one already?

"Skylab Operations Handbook"

https://ntrs.nasa.gov/api/citations/20160013590/downloads/20160013590.pdf

The drawings and the monochrome photos in that digitized manual are very good, they might help you a lot.

Page 101 has an excellent good drawing of the support structures you are fighting with.

 

[gattispilot]

We know the trusses are at 90 degrees.
So the door there will be a thicker part.
those part of the sides of the hatch are not on a 45 degree. But the drawing shows them on the point of the octagon.
I think the truss on the sides of the hatch are different?
the hatch would hit the pole of the truss.
I added a ladder to the ATM. But now I question the orientation. Because the handrail on the sun part looks like it is near the ladder?

I am looking for some cross sections views

 

[gattispilot]

Thanks.
now we get these:
So the edges that the truss attach are small than the long edge. Not sure if the hatch area is extended? The web shears i guess connect the tunnel to the truss? only 1 on the airlock side. Not sure if the hatch will still hit the truss? i would like to find a cross section of where the hatch is. here the hatch is open 90 degrees and it will hit the truss

 

[Urwumpe]

I think you also have the reference image mirrored to the mesh.

 

[gattispilot]

Maybe. In the image and mesh Z+ is up and z- is down. Maybe the Y. But I took the hatch from the mesh and just opened it up. It looks like that blue part is close to the hatch. The orange piece is missing?
Handrails on the STS

 

[Urwumpe]

The basic truss assembly (figure 2.0.8-14) is typical for three of the assemblies. The fourth assembly is
similar except the secondary members were relocated and made removable since this truss is mounted near the EVA bay.

On page 95, "2.0.8.3.4 AM Support Truss Assemblies"

 

[gattispilot]

Ok. so the secondary are the WEB parts. So the truss still mount on 90 degrees?

where that info

 

[Urwumpe]

They are not the web parts, as far as I can tell, since the web parts are part of the pressurized structure, not the AM support structures. Also, your hatch is not elevated from the cylindrical hull, like the real one, which should change your geometric validation results about its motion range.

 

[gattispilot]

Better. I need to look at the ATM suns part.
So if the ladder is at the top. Then the handhold is wrong. I can put a foot restrain there also.

 

[Urwumpe]

You know were the "fixed" foot restraints were?

 

[Urwumpe]

You can find the position of the handrails around page 379 of the Operations Handbook, including the alphanumeric codes for them to identify the handrails.

The text around these pages also contains information, where the mobile aids are stowed around the EVA bay, if not in use.

 

[gattispilot]

I believe there are 1 or 2 in the eva bay area. and one here on the front of the ATM.

Thanks. Not sure about texturing the numbers

 

[Urwumpe]

Not needed to texture the numbers, I think they are only for reference when planning an EVA. But the codes also allow you to easily check if you have missed one.

You have 8 handrails (A1-A8) and two EVA workstations (foot restraints) on the ATM, 5 (D1-D5) along the deployment truss (DA) and 15 handrails (F1-F15) on top or inside the Fixed Airlock Shroud (FAS). There are also two moveable PGA foot restraint inside the FAS.

 

[gattispilot]

i think handrails and restraits are good. 2 foot restraints on the ATM

 

[Urwumpe]

Can you put some (two sided) foil over the FAS? You can't see the oxygen tanks from outside easily, there is only a cutout over the EVA bay.

See this picture from a Skylab flyby:

 

[gattispilot]

Sure. I guess I can cover/remove the truss outside of the eva bay in the original mesh that's how it was.

I will remove anything hidden. And add some details on the bottom from the image and add red/green lights

 

[Urwumpe]

I wouldn't really remove the AM support trusses, unless they are really invisible. If we could do an EVA in Orbiter AND see the truss structures (or even use them for moving in a real EVA kind of motion), they would be great. We need a lot of detail close to the EVA bay, the ATM and the MDA, because that is the parts of Skylab that players will really see most of the time and where every detail can be a gain.

 

[gattispilot]

With the covered area and not. And eva bay. all but parts of the truss around the bay are seen.

I need to accent the door. It should have a handle.

 

[Urwumpe]

Can you make two test renders looking left and right from the EVA hatch?

 

[gattispilot]

I think the hatch is wrong. The window looks larger. The elevated part is curved, More at the bottom than the top and angled? more at the front than the bottom.

I think the inside skirt needs textured to give it depth
