Centaur G/G Prime High Energy Upper Stage

2 pipes to go.

Final UVW map. That's most complex unwraping I've ever made.

Need bit of a break - all is to do is texturing.

Loru: How far have you come on the engine? We would like to include the new Centaur mesh/textures in the upcoming SSU public release and the only thing holding up the Centaur hardware is the engine.
 
I need ~4 - 6 hours for the texture or I can ship you engine as in last screenshot with PSD file containing all groups needed for color, normal and specular maps (UVW and ambient map included).

I think it's better that you take care of the texture as you're more familiar with it.
 
Sure. Saturday is deadline then

Sounds good.

Question: How will we proceed for the release regarding the Centaur Mission Kit elements? Should I make them part of the CISS mesh files or should they be their own mesh file so that they can be flown without the CISS?

This is what I have of the Mission Kit so far:

And this is the new CISS, without the Mission Kit elements:

Is it possible to separate them in the future? If so (and it isn't too much work), I vote for having all in one piece for now, and when we get to a point where we can choose vehicle configuration "with ease", then it will make sense to be separate.

They're separate right now but it's easy making them as one.

A summary of what is required prior to release (feel free to add if you know something that is missing on the list):

  • Animation of the articulated fluid ducts on the CISS
  • Animation of the Deployment Adapter on the CISS
  • Working MPS and RCS on the Centaur
  • Both versions of the Centaur/CISS (G/G Prime)
  • Accurate flight-plans for Ulysses/Galileo trajectories

[1]Animation of the articulated fluid ducts on the CISS
[2]Animation of the Deployment Adapter on the CISS
[3]Working MPS and RCS on the Centaur
[4]Both versions of the Centaur/CISS (G/G Prime)
[5]Accurate flight-plans for Ulysses/Galileo trajectories

[1][2] don't know animations :(
[3] working RL-10 and RCS (just waiting for mesh to fine tune coordinates). no tanking or dump capability yet
[4] code is ready for 2 versions
[5] not sure we need that if we don't have the probes... using the current launch times, deploying on orbit 3 and burning +/- on the descending node over South America, it goes "in the general direction" of Jupiter :lol:. I'm sure using TransX, or something good like that, it's possible to get to Jupiter without more than "Centaur deployment: orbit 3. Centaur burn: 45 minutes after deployment. Backup deployment opportunities: orbit 4 and 5".
 
Loru: Do you think you could create a texture of the CISS Deployment Adapter that you have done for the RL-10? I'm thinking more specifically of the coolant tubes of the nozzles. As you can see in this screenshot of the DA WIP, it has 60 stringers on the outside and another 60 on an inside ring.

I was thinking that a nice shaded texture would make them stand out more than a regular blank texture.

its really easy, especially if you just stick to rotations and translations.

But I can't do it this weekend, lots of social stuff, if you have questions, I can answer them before friday afternoon.

I'll take a pass, for now. I'm too "fried" at the moment to learn new stuff. Maybe in the summer, if I have time...

No deal.

Actually it isn't really that much stuff. The biggest challenge is getting used to thinking in animations. If you ever had some lectures about robotics, its exactly the same kind of stuff as textbook forward kinematics.

Maybe I can take a look at the animations on sunday evening.

The animations for the articulated fluid ducts are standard rotations. The data for these are in this post: http://www.orbiter-forum.com/showthread.php?p=405637&postcount=147

The only thing I haven't managed to figure out is the animation data for the rotation assembly hardware (cranks and links).

Current status of the new CISS. I would estimate another 1-2 days of work left. Current config is for the Centaur G. The only real difference between the G and G Prime CISS is that the G Prime CISS has another set of Helium bottles between the two U shaped yokes which increases the length between the forward and aft yokes.

Since almost everu picture of RL-10 has different color of turbopump assembly what color should I make it??

Grey or black? Also should I make some of the elements yellow like in one of the pictures?

I think the black/yellow items are protective "Remove Before Flight" covers. These covers are usually red but I have seen them in other colors as well.
 
In second picture entire turbopump is black while in first it's "rusty" grey. What color should I make it then?

Make it plain gray. The black as I wrote is most likely a set of "Remove Before Flight" covers designed to protect sensitive hardware during pre-launch processing. They're removed as part of the standard close-out activities.
