SSU Launch Complex 39 development

[SiameseCat]

I'm not sure what's happening here; I tried the vent code using the current pad mesh and everything works (although the vent positions are slightly off). Can you check the code in so I can take a look? Use a LC-39 branch if the new pad isn't ready for the main branch.

I created a new branch and checked in what I got right now.

Checked in a fix for the vent code.

Thanks. I reviewed the modified lines and see the obvious problems.

Now that SSU v3.0 has been released I can get back to updating LC 39. The first one to near completion is the MLP. The following two screenshots are of the new Tail Service Mast blast structure. As you can tell, it's far more detailed and correct in dimensions.

The latest work, now featuring the side ladder as well as the GH2 burn off igniters.

There was, only during the 90s, a "tower" between the SRB exhaust holes that was to release GN2 or something (some years ago I knew but forgot :facepalm. Could this be added? We could show/hide as needed.
Here are some videos that show it show up and disappear (visible behind the SSMEs at ignition).

This is the new carrier plate for the LH2 TSM, showing the orbiter side.

[DaveS]

For the moment I have run dry on reference material on the carrier plate for the LOX TSM so I've decided to return to the FSS. I'm nearly done with the structural work on the 215 level of the IAA support structure.

Any thoughts on parts of the lunch tower missing ?

the tower structure is missing. the white room and fuel cap and some of the floors are there

On what? In the screenshots of the IAA support structure? I'm doing that one away from the main FSS project file as so not to screw anything up. This is how the real IAA support structure was constructed. It was fully constructed offsite and then trucked to the pad(s) and lifted into place through the use of a large mobile crane. Oh and it's not the "fuel cap". It's the Gaseous Oxygen Vent Hood, or GOX Vent Hood if you prefer it that way. And GOX is the boiled off state of the the oxidizer, LOX. The fuel is LH2 and it is not vented freely but burned off at a flare-stack north-east of the hardstand.

No new screenshots but just a general update: After alot of trial&error I believe I have finally gotten the 215' level of the IAA support structure more or less done.

The problems has mainly been due to the severe fact that I do not have any dimensional data at all on the GH2 vent line haunch as well as the IAA support structure itself besides the three-level section that is directly attached to the north side of the FSS. So everything has been mostly a guessing game making everything fit the various photos available.

The work on the External Tank Vent Arm System (ETVAS, the official name for the GH2 vent system) has now been completed and work will resume on the IAA support structure.

Latest update on the IAA support structure. Not really that much since I haven't had the time to work on it. The 215' level is about the done, right now researching the 205' level:

The IAA support structure is now more or less structurally completed leaving only outfitting left.

Almost done with the IAA support structure. The only thing left is the IAA itself as well as the cross bracing on the north side as well lengthening the entire structure a bit (you can see that the ETVAS haunch is not quite sitting on the structure in the first screenshot of the south side).

[DaveS]

Well, almost there now. Only some external cross-braces left as well the internal cross-braces on levels 195 and 186. Then I'll be able to focus on the IAA and equipment outfitting.

The IAA is now nearly done, minus some structural work.
