Request Soyuz descent RCS thrusters

george7378 · Sep 25, 2009

Hi all,

I have a request for any C++ coders here:

I have this Soyuz TMA addon:

[ame="http://www.orbithangar.com/searchid.php?ID=3784"]Soyuz TMA spacecraft[/ame]

but the descent module has no RCS thrusters. Could anyone please add an RCS to the descent module (another state of the main TMA, so you need to edit the code for that)? The source code is included in the download, so no need to decompile.

I have asked for this in other threads, and have received 'download this instead' or 'this is just old - why do you want ot do it'. If you can do it, I would be very pleased.

Here is the source code:

OK, I will make you a version this evening, if this makes you happy. I wanted to do something else, but I am not really mentally ready to make meshes (which brings more frustration than I can take)

george7378 · Sep 25, 2009

Yay!!

Thankyou so much

You are a legend.

I have tried meshes before (for FS2004), in Gmax, and I have managed to make some reasonable scenery, but never managed to make an aircraft.

Thanks again

OK, I will make you a version this evening, if this makes you happy. I wanted to do something else, but I am not really mentally ready to make meshes (which brings more frustration than I can take)

Dennis, I recommend trying to add the COG shifting means as well for better realism... Although, I'm afraid, that might require some non-generic inputs.

Well, most stuff like that can be found in a book I own. But what current disturbs is that the RCS thrusters (in wrong position) actually existed in the Soyuz code on my HD, but are not working because they are always out of fuel. Is no scenario bug, but rather a problem during staging, there seems to be a propellant resource bug.

Is that likely to be a large problem?

Yes. Because it is still not solved.

OK, well if this is too large a problem, then thanks for trying.

Does it mean that you can't continue?

No, it means I need to reorganize the code a bit and remove the grown code, so I can debug it and have a chance to follow the execution of the module. Started this last night, but need a bit more time then just for adding the thrusters. Will then also move the thrusters to the right positions and include the CoG offset.

But this will now have to wait until the evening, when I am done with housekeeping.

Thankyou, once again, for all your help

Still I don't understand why you don't want to use the more recent Soyuz TMA by Thorton.

I would, but it won't work with the Soyuz series launchers, (I get bad FPS with project R7, and I can't use the Baikonur scenery), and the OFSS missions require the TMA you are working on.

Also, none of the ISS V2.0.5 scenarios work for me - all crash my program.

It has to be possible to stick the Soyuz from that onto the Soyuz series launchers. Everything in orbiter is like lego - just sticking bits to bits.

As do many other scenarios. I think you need to have a clean reinstall of orbiter.

Urwumpe · Sep 26, 2009

Well, anyway. I will look at getting things sorted and put the source code on a more solid base, it is not like Highlander here (There can only be one)

(Also I still think astronaut made the best [ame="http://www.orbithangar.com/searchid.php?ID=2844"]soyuz launcher[/ame] add-on, followed directly by my own meshes in Sputniks [ame="http://www.orbithangar.com/searchid.php?ID=3388"]Velcro Rockets[/ame] add-on :lol: )

I like Mustard's one because of the meshes and textures, plus the compatibility with the Baikonur LC1 pad 5 scenery, and the autopilot system.

I will have to try Velcro - it does look fun to use, especially if you are interested in (or looking for inspiration for) spacecraft design.

Have you got any progress updates with this?
