Space Shuttle Ultra 1.25 Revision B development

[DaveS]

Checked in a DFI pallet that was used on the first five flights. Please do note that for STS-1 only the pallet was located in Bay 9 and was relocated to Bay 11 for missions STS-3 through STS-5. It was also carried on STS-8 in Bay 8 but with no visible wiring like on the Columbia missions.

 

[DaveS]

Checked in a SWT mesh with associated textures.

I can also confirm Donamy's bug report a while back about the GH2 venting after separation.

 

[Donamy]

Also need to get the burnt ET texture back.

Yes.

Checked in the code for the different ET types and to fix the ET venting.

ET venting bug has been fixed. Another thing: Could you implement the Ha and Hp parameters in the OMS software?

I can, but it won't handle nonspherical gravity well, so the values won't be particularly accurate.

Well, I guess we just have to put a note about it and live with it.

Give me some time to locate the lecture notes, then I can give you a fitting formula for the eccentricity correction.

 

[SiameseCat]

I had a look at KOST ([ame="http://www.orbithangar.com/searchid.php?ID=3825"]KOST 0.75[/ame]) and it looks like it might also be helpful, especially when we get around to implementing the rendezvous targeting stuff.

The pad offset in the Crawler code needs to be adjusted. Currently this prevents the MLP from being secured at the pad following a rollout.

I'm trying to fix this bug but can't find the code that controls the height when on the pad. Any tips on which lines I should edit?

 

[SiameseCat]

The height is defined in CalcRampHeight (Crawler.h, line 267). It's currently set at 15.4, you can replace this number (it occurs twice) with the corrected height.

Thanks. The problem with the height when level on the pad surface has now been fixed although there's still a similar problem when ascending/descending the pad ramp. Which line controls this?

 

[SiameseCat]

The changes you made should fix the ramp as well. Is this problem with a different pad mesh from the current one? I tried the crawler with the new heights and it seems to sink into the pad.

Weired. It's the current one. This is how it looks for me:

Here's the Crawler at the top of the pad for me. The scenario file is below, if you want to try it.

Tried it and the Crawler was parked nicely on the pad surface. Could you maybe remove the commented out save/load sections for HEIGHT? It should be 14.45 14.45.

Here's my SSU_Crawler.dll for your debugging uses: http://dl.dropbox.com/u/24122088/SSU_Crawler.zip

 

[SiameseCat]

Same thing happens with your dll. Have you changed the code for the pad?

 

[DaveS]

Yes. I could check it in if you want.

 

[SiameseCat]

Check it in; that might be causing the difference.
