Hey Vincent, be more precise.
You have been in Orbit for a day. But did you let the computer opened 24 hours with FG running or save and resume?

Next time take a screenshot of what happens.

Here the hint from EatDirt, look at Spec 69 in Orbit with SM ( System Management) Major Function, you should see that

If something is wrong with Fuel Cell, you should the voltage below 28 V ( red markers) meaning contaminants may be present in the cell and a purge is needed

I will give the fuel cell purge a shot! I got a suggestion: is the space shuttle flight and space shuttle systems operation tutorial on YouTube as well! Thanks!

Cheers,
Vincent

Not so sure what this is, but its breaking the trajectory map.

Edit - seems to be missing
<inclination-targeting type="int">1</inclination-targeting> in mission.xml provided by GinGin. Not quite sure what its value is meant to be so setting 1 to see...

Yep - old mission file format. Don't worry about the value, it's experimental and not documented yet, just set it to 1.

Hello Thorsten, I am back with a couple of questions I noted during my last sessions.


1) I was looking to a way to see the drag acceleration wise during entry, could tell me where to look in those parameters ?

I was wondering what is nlf parameter meaning?

Image


Is a pilot on x axis close to deceleration value D coming from drag during entry?

Image



2)Is there a way to copy/Paste directly the state vector time stamp from game to a file ?


3)I am coming back about the 40000 pounds in addition in SHuttle .xml

Code: Select all
   </location>
        <pointmass name="Equipment">
            <weight unit="LBS"> 40000 </weight>
            <location name="POINTMASS" unit="M">
                <x>  2.7 </x>
                <y>  0.0 </y>
                <z> -2.7 </z>
            </location>



It is more a feedback than a question. I am playing with just a 5000 pounds value ( to take into account all the cryo stuff) and didn't see any consequences.
Shuttle weights are also really way closer to reality without those 40000 pounds

It's probably quite good. Usually the location of the accelerometer matters only if rotational acceleration is involved - which is small during entry.

I was wondering what is nlf parameter meaning?


No idea - normal force perhaps? There's plenty JSBSim creates by default.

2)Is there a way to copy/Paste directly the state vector time stamp from game to a file ?


If you save the state, among other things the state vector and timestamp are dumped to file. Otherwise there's not - the state is also written to the console, so if you need it in LEO targeting, copy/paste is what I do.

I am playing with just a 5000 pounds value ( to take into account all the cryo stuff) and didn't see any consequences.


Okay, since I've still not figured out what my idea was, I suppose we'll lower the number prior to the next release.

Interesting, fully loaded, Space Lab weighted 30000 pounds ish
