Project Updated SLS for Orbiter 2016 (and 2010)

gattispilot · Nov 28, 2016

On the tower. It uses the old style of touchdown points. But when I detach the tower starts to spin.

Not sure why it is not landed?

So how to make it landed? When placed by the crawler it is off the ground enough for the crawler to go under and get her.

gattispilot · Nov 30, 2016

I am out of ideas. It seems when I detach the tower it drops and then spins.

I have tried SC4 and same results. Tried changing touchdown points, mass,....

Do other projects have the same problem with the touchdown points? I thought SSU crawler experienced the same problem but the crawler of Fred18 apparently not. Have you tried more touchdown points? 5, 6, 7?

gattispilot · Nov 30, 2016

Not sure. I will try to release/attach the tower with fred's crawler.

I think is it thinks the tower is not landed. Fred did a hack I might try that writes to the scenario that the vessel is landed.

I am working on the 2010 sls crawler, adding sounds,....

the new touchdown points are a bit difficult to handle but martin provided quite a good explanation of how to manage them:
http://www.orbiter-forum.com/showthread.php?p=544979&postcount=88

If you solve the equations then it becomes easier to have good behaviours.
I gave a small example here, it works quite fine to me for touchdown points with same distance from CoG (of course the equantions provided there should be changed if the distance from CoG is different for each point, note that 9.80655 is just gravity acceleration value):
http://www.orbiter-forum.com/showthread.php?p=546788&postcount=91

Adding touchdown points will not help anyway, since the upright status is determind only by the first three (is like the gear of an airplane).

Relevant to MS crawler I found out at the time that the clbksavestate function did not save the arot parameter for landed vessels, so I had to write a hack to went around that issue. Now in the meantime this issue was solved in the svn version of orbiter, and still in the meantime I found a way to calculate the arot parameter by myself so I'll change the code of the crawler, taking away the hack and inserting the code that properly calculates the arot parameter by itself, working with all orbiter versions without hacks anymore. It still will take some time because I'm out of coding for a couple of weeks more due to real life issues.

gattispilot · Dec 2, 2016

Same effect. When the tower is detached form either crawler. it is ok til it comes into ground contact and then spins out of control

---------- Post added 12-02-16 at 04:32 AM ---------- Previous post was 12-01-16 at 05:16 AM ----------

I tried Fred's hack.

Code:

void SLSTOWER2::clbkPostStep(double simt, double simdt, double mjd)
{
    VESSELSTATUS2 vs2;
    memset(&vs2, 0, sizeof(vs2));
    vs2.version = 2;
    GetStatusEx(&vs2);


    {
        FILEHANDLE fh = oapiOpenFile("SLSTOWER2016", FILE_OUT, CONFIG);
        oapiWriteScenario_string(fh, "STATUS", "Landed Earth");
        oapiWriteScenario_float(fh, "HEADING", vs2.surf_hdg*DEG);
        oapiCloseFile(fh, FILE_OUT);
        fh = oapiOpenFile("SLSTOWER2016", FILE_IN, CONFIG);
        clbkLoadStateEx(fh, &vs2);
        oapiCloseFile(fh, FILE_IN);
    }

But nothing. It is good till it is detached. I think it might be a touchdown issue?

Dude pls fix the Developer thingy in the scenarios because they don't load any thing...

---------- Post added at 12:32 PM ---------- Previous post was at 12:18 PM ----------

Oh yeah Longjap, thx for the Textures for the EUS but I think the problem is the Mesh which I fixed ( and tested several times) and has a lower fail rate!!!

Astro SG Wise · Dec 2, 2016

My Orbiter crashed most of the time during separations and even when just using Orion. Its really annoying. By the way, great awesome SLS, and it works most all the time, just a few times when it shuts off unexpectedly.

pclaurent · Dec 4, 2016

Really promising add-on, and very nice design. When travelling to the moon with ICPS ou EUS, however, if I exit during the TLI (somewhere between earth and moon), Orbiter cannot restart to this point. The saved scenario crashes immediately when loaded. I'd already noticed that with a previous version of Multistage and Orbiter 2016.

gattispilot · Dec 5, 2016

Can you post the log/scn?

I am working on a new pad and attachments for the spotlights. I have a beta for the sls crawler for 2010 around. Major issues with the tower in 2016.

So I guess we need a feet for the launchpad in the VAB. Then use the crawler to move the pad and rocket from VAB to launchpad hill

Doable now. Not sure if the VAB doors open though?

pclaurent · Dec 7, 2016

Strange... During the trip to the moon, after quicksave and restart, the Orion LAS is attached to Orion (it had been properly jetisoned after launch). Quicksaved scenario below:

Messed around with some pre-existing meshes and made a pretty respectable Orion/EUS adapter for SLS Block 1B.

I ran the scenario that pclaurent posted. The las is separated but you see it here.

Do we need the VAB doors to be animated? I think I can do it
It looks lik the doors just go up. The bottom doors open to the side?

Here's the two videos from the STS-125 Bay-To.Bay transfer of the SRB/ET stack back in 2009:

gattispilot · Dec 9, 2016

Thanks. I will see what I can. The VAB mesh has an interior. Will will just get the high bay doors to open

gattispilot · Dec 14, 2016

This was the default VAB. I animated the doors and added an basic interior. This is my crawler leaving the building. I haven't placed it yet. the 4 high bay doors and 2 side smaller doors will open

Thanks. I guess the next step is to change the base.cfg to remove the default VAB. Then I should be able to drive a crawler from the vab to hill and back.

This is all for 2010. I have a crawler that works (drives and climbs the hill) in 2016. But it will not release the tower without it spinning

.

I got the crawler to climb the hill by moving the mesh. I thought about that for the tower but even on the ground when you detach it spins around.

Not sure why the status is not always landed
Here tower is attached.

But in the code for the tower I have this:

Code:

void SLSTOWER2::clbkPreStep(double SimT, double SimDT, double MJD) {

	VESSELSTATUS2 vs2;
	memset(&vs2, 0, sizeof(vs2));
	vs2.version = 2;
	GetStatusEx(&vs2);
	
	{
		FILEHANDLE fh = oapiOpenFile("SLSTOWER2016", FILE_OUT, CONFIG);
		oapiWriteScenario_string(fh, "STATUS", "Landed Earth");
		oapiWriteScenario_float(fh, "HEADING", vs2.surf_hdg*DEG);
		oapiCloseFile(fh, FILE_OUT);
		fh = oapiOpenFile("SLSTOWER2016", FILE_IN, CONFIG);
		clbkLoadStateEx(fh, &vs2);
		oapiCloseFile(fh, FILE_IN);
	}
