Project Multistage2015 - Development Thread

[Kyle]

Is there anyway in MS2015 to be able to tell the autopilot what altitude/inclination you want to achieve during a stage re-ignition once on orbit? For example, I'm trying to place EFT-1 into a -34kmx5808km orbit after it completed its first orbit around the Earth at MET +1hr55m.

I'm sorry I have to say that I didn't fully understand the question:

if you plug into the orbit autopilot -34 , 5808 and inclination and a target abside what do you get?

I'm sorry I have to say that I didn't fully understand the question:

if you plug into the orbit autopilot -34 , 5808 and inclination and a target abside what do you get?

Sorry if I'm not making any sense. I'll show you my GNC file:

0=orbit(185, 888, 28.532, 1)
-5.5=engine(0, 100, 2.7)
375=fairing()
380=les()
6909=orbit(-34,5808,28.532,1)

Basically I'm trying to command the autopilot to re-ignite the engine at MET+6909 to raise the Orion capsule's orbit from its parking orbit of 185x888km to a final orbit of -34x5808km. However, when I do this MS2015 automatically tries to put the launch vehicle on a -34x5808km orbit during launch as opposed to a 185x888km orbit.

I don't think the autopilot can handle multiple orbit calls.

Also, I don't think that the PEG routine knows enough about orbital mechanics on its own to do what you want.

Try some of the other commands:

Defap(xx) to go prograde,
engine(xx,yy,zz) to turn on engine
Target(xx) to get to the required apogee.

 

[Kyle]

Ah, just a classic case of RTFM on my part. I'll give that a spin! Thank you.

200% correct, thanks boogabooga :tiphat:

autopilot can hold just 1 orbit call, if you put more than one it will use the last (as you experienced). There are many other calls that you can use, some close loop like Target(xx), some open loop like Attitude, Defap etc. It's up to you to choose your favourite combination.

Hey, I checked out the latest version of Multistage 2015 for Orbiter 2010 P1, and the playsound feature isn't working for me. In the guidance files for my Saturn rockets, I have countdown audio that plays at T-10 seconds. It worked fine in previous versions of Multistage 2015 but it doesn't work in the latest version. When I press the key to launch the rocket when using the latest version, the countdown starts but the audio doesn't play.

Hi jacques,

not yet: orbiter sound is ready to be implemented but it will not be until orbiter sound for orbiter2016 comes out.

By (my) mistake also in 2010 is not implemented at the moment. I will add orbiter sound to both 2010 and 2016 as soon as the new version will be out.

I have to say that I don't know how long will it be from dansteph, if it takes too long I'll add it with the current version, I'll just wait a bit more.

Ah, nevermind, I'm just now seeing this.

 

[boogabooga]

Hey Fred, there has been no activity from Dan Steph in months. Even if a new version of Orbiter sound comes out, chances are it will only be compatible with Orbiter 2016 anyway. I wouldn't expect any changes in Orbiter Sound for Orbiter 2010.

I would recommend re-establishing the playsound feature for the Orbiter 2010 version.

For Orbiter 2016, it's absence perhaps can't be helped.

I agree, I've been thinking about this. I was finishing to code the Space Network plugin and started to think to add sound to that, but I got overwhelmed by real life in the last few weeks. So the plan is to finish the plugin and then get back here and add sound support and to change one thing in the crawler. If in the meantime Orbiter Sound 2016 comes out good, otherwise I'll reupdate the addon later on.

 

[jacquesmomo]

Hello Fred

I would like to know if it is possible to use the "crawler" without the "hangar" ?
(With the rocket attached to the crawler ... and no hangar visible in the scenario).

I did not succeed to make a scenario with the crawler functional and without the hangar.

[LATER] oh... sorry.. I found it !.... Yes, we can :blink: :blush: [/LATER]

 

[Fixerger]

This is must have module. Thank you.

 

[gattispilot]

For payload: Is there a way to load a cfg'ed vessel with saved animations?

So that when you add a vessel that the animation or state needs to be different than default. Here the TS_Tugboat is loaded. But the payload just loads a mesh

Make it a live payload (live = 1) , jump into your payload with F3, set the animations as you wish them to be and save the scenario

 

[gattispilot]

Thanks that worked. For some reason the SLS isn't launching correctly. I press P and nothing press again and she is spinning in space.

 

[gattispilot]

I am trying to get a cargo version of sls to work.

So I have this for scn:

It seems to me that it doesn't read the ini file at all. Are you sure the ini has the correct name?

 

[gattispilot]

Thanks.

Yes that was it. All though when i load the CArgo Block II ,... ini there seem to be some missing meshes?

Ok this is what I get when I load the CArgoII one. See the missing meshes.

I just think how to make realistic shuttle roll program entry in guidance file. Somehow it happens too late - 15 secs into the flight and is slower than usually. Something's not right. Does anybody know? My typical guidance file is as follows:

-10.000 =orbit(88.0,296.1,28.55)
-6=engine(0,100,6)
-5=PlaySound(sound\multistage\atlantis_launch.wav)
4.0 =roll(4,90,90,78,-1)
20.0 =pitch(78,18,105)
30.5 =engine(100.00,67.00,5.00)
65.0 =engine(67.00,104.00,5.00)
122.0 =jettison()
122.0 =pitch(18,10,388)
