Update TransX development

[Enjo]

BTC: include RCS

As per blixel's request, the BTC now has an "include RCS" button, similar to Ext, but automatically taking into account RCS fuel, for more precise DV budget considerations.

Is it possible to give the Outward Vel constraint in TransX's Auto-Min a little bit more "room"?
By using the Auto-Min in all three variables and changing the date, I have noticed that TransX "misses" some launch opportunities (or it displays more dV than what is needed). It always happens with the Outward maxed out at ±1000.
If it was possible to connect the Outward constraint to 75% of the hohmann transfer, I think it would be able to catch those (otherwise counter-intuitive) transfer trajectories.

That is IF it is easy to implement. Otherwise no need to bother, all it takes is a bit of manual tuning.

 

[Enjo]

Sure it's possible and it's very easy. The problem is that the solver may prefer suboptimal solutions, but this is what is assumed when you include Outward Vel anyway.

Could you post a scenario with a plan, having a minimized Cl. App. so I can immediately try if the Auto-Min results are sane?

 

[dgatsoulis]

I'll be able to in ~ 1 hour.

 

[dgatsoulis]

The scenarios are attached on the bottom of this post.
Both of them leave on the same date: Feb 29 2016

The 2016 - TransX long uses:
Pro : 2503
Out : -1236
Ch.Pl: - 955.8
Total: 2951 m/s TOF: 307.9 days

The 2016 - TransX short uses:
Pro: 2441
Out: 1331
Pl.Ch.: 1325
Total: 3080 m/s TOF: 176.1 days

The trade-off is small (129 m/s) to save 132 days of flight.
The Auto-Min isn't able to "catch" either of these plans due to the Outward being beyond the ±1000 constraint.

In all fairness, those plans are less than optimal and TransX did catch a slightly cheaper plan (TotalDV: 2850 m/s - TOF 189.6 ) ~12 days prior to the launch date of these plans, but I think raising the constraint will give it more flexibility.

If you think that this can be done without creating more problems than it will solve, then it would be great. If not, leave it as it is.

 

[Ripley]

Can't see it. You need to make it available to anyone that has the link...

Should be visible now.

Thanks Enjo. This will be very helpful.

There are a couple of logic problems with this build though. If you switch ENG type to RCS, it doesn't seem to count the fuel that you have in the Main tank - which makes sense. But if you switch to RCS engine type and press the new RCS button, it seems to count the RCS fuel x2

I've attached a scenario you can work with that has very limited fuel.

EDIT: This scenario starts with exactly 311.787 m/s remaining.

Indeed. That was easy.

 

[blixel]

Indeed. That was easy.

Looks good. I tested several different situations. Transferred all the fuel to RCS, transferred all the fuel to the Main, left some in the RCS and some in the main. In all situations the reported dV was correct with the new RCS button.

Nice work Enjo!

 

[Enjo]

dgat: I was experimenting with the scenarios and as far as I can see, even with greater OV margin, you are able to find the solutions automatically only if the PV isn't minimized together with the other two velocities. I need to spend some more time on it.

 

[dgatsoulis]

If it's too much trouble, forget about it. Auto-Min has already sped up the process by at least x10. Those scenarios and others like it, are special cases.

 

[Ripley]

New versions up!
I guess betatest is officially closed?

 

[Enjo]

You are always welcome to test my stuff, but yes, you could say so. Thanks for all your help and for confirming my assumptions.
Let this be a reminder for us all - always test on a clean installation before drawing any conclusions.

 

[Interceptor]

Thanks Enjo,dgat,Ripley,blixel,and all the others for helping make transX,and Burntime calculator,better,and more stable.

 

[Ripley]

Enjo, is ModuleMessaging required by TransX, or is it optional?

 

[Interceptor]

OK Enjo,I found a bug in transX,sometimes when you press the ++ it switches it to the target view.

 

[Enjo]

Enjo, is ModuleMessaging required by TransX, or is it optional?

I know what you're up to - the TransX OH description, which doesn't mention MM explicitly Oh, if only the download count wasn't reset when just updating the description. My addons would have teh bes descriptionz evar... (OK. Growing up! Growing up!)

OK Enjo,I found a bug in transX,sometimes when you press the ++ it switches it to the target view.

More info please. Ideally a solid reconstruction script.

 

[Ripley]

I know what you're up to - the TransX OH description, which doesn't mention MM explicitly ...

Exactly!
I knew you were a brilliant developer, but I didn't know that you could read people's mind :lol:

I asked it because of this screenshot, posted by a new FOI member:

It says "ModuleMessaging.dll not found. Couldn't launch program".

...Oh, if only the download count wasn't reset when just updating the description...

What?
You have both "Downloads Since Update" and "Total Downloads"...

 

[Interceptor]

OK Enjo,I found a bug in transX,sometimes when you press the ++ it switches it to the target view.

Enjo,this problem seems to happen when I am on my way to the moon,and just out of the Earths SOI,when I go to start my first mid course correction,and switch the maneuver mode on,as soon as I switch to outward vel,or change plane,and then use the --,or the ++ to change the value that's when it all of a sudden switches to the target view.

 

[Enjo]

What?
You have both "Downloads Since Update" and "Total Downloads"...

After like 6th release the total download count doesn't tell much anymore.
