Space Shuttle Ultra 1.25 Revision B development

[DaveS]

Need a little help: the position of the ET vent and the LOX dump aren't correct anymore (mesh change?), so if somebody could get me the correct values for the SSMEs and the ET vent it would be very helpful. Thanks! :tiphat:

SSME vents are OK, and only the GH2 venting has been implemented. Here's the new coordinates for the GH2 vent:

-3.12321 -2.36732 13.4955
0.788011 0.615661 0

---------- Post added at 01:41 AM ---------- Previous post was at 01:34 AM ----------

Checked in the fix.

Checked a fix for the oversized SRB exhaust. Cut the GROWTHRATE in half (30 to 15).

Thanks! But about the SSMEs, I'm making the post MECO LOX dump (not the pad stuff) so....

LOX is dumped through the SSMEs right? Then you should be able to use the position and vectors of the SSME exhaust renderings.

Position for the LH2 dump port on the aft engine compartment:

-3.33 -1.31 -7.02

Ok, I'll try that! I'm going to leave the LH2 dump for later, when I find the right place to put all the dump start/stop commands.
Another thing, the long throw igniters on the TSMs are also off by a bit (too much to the north).
Sorry to bother and thanks very much!

Would be nice to stow the SSMEs after SEP

Committed new KU mesh, but I can't seem to commit the new KU.dds:shrug:

If it is a new file, you need to add it to the version management.

 

[Donamy]

No, it is a modified file.

 

[DaveS]

If it is a new file, you need to add it to the version management.

Considering all the other Ku band DA meshes have used it, there shouldn't be a problem. Updated the code to use the new updated DA mesh.

No, it is a modified file.

What is the error message when you try to commit the file?

 

[Donamy]

It just doesn't do anything.

---------- Post added at 07:32 PM ---------- Previous post was at 07:14 PM ----------

New KU.dds committed.

 

[Poscik]

Any chance to have simple tool that calculates speed needed to beat RInc down? As we can't burn OMS by hand, it's quite difficult to do that. Or I just need equation, and I'll do such app. I only (I think) figured out simple equation to beat inclination difference, not LAN. It looks like x = v*tg(a) where x is velcotiy needed to beat inclination difference of 'a' when travelling with speed of v.

Shoot me if I'm wrong

 

[Urwumpe]

The data you enter is simply the difference between your velocity vector now and the velocity vector for the new orbit.

 

[Donamy]

I have this problem. The grapple point iss too far into the EE.

 

[Poscik]

The data you enter is simply the difference between your velocity vector now and the velocity vector for the new orbit.

But I have to caluclate new orbit velocity vector somehow

That...is left to the students. :lol:

No idea what went wrong with sourceforge, but here it works well.

I have found some pre-launch sound clips from STS-100/6A in April 2001. Could these be implemented if I check them in?
