I don't know where the springs are (IUS or ASE for sure), but it doesn't matter. The speed value is probably somewhere in some document, and that's all that you need. Can't help more.

Well, at 2.1ft/s takes 93.7s to travel 60m, so I'd say a 90-100s timer would do it.

I see the problem as when the timer starts? I know when it get dettached but how to you tell the vessel that

Code:
if ((GetAttachmentStatus(STAGE1)) && (STAGESELECTION == FIRSTSTAGE))//2ND STAGE IS ATTACHED TO 1ST STAGE
{
newmass = STAGE1MASS+STAGE2MASS; //MASS OF STAGE 1 AND STAGE 2 ARE ADDED
SetEmptyMass (newmass); //NEW MASS OF STAGE 2 AND STAGE 1
MAX_MAIN_THRUST = 184752.84; // THRUST OF STAGE 1
MAX_MAIN_FUEL = (9631+ 2727.45); // FUEL OF STAGE1
SetThrusterIsp(th_main[0], 2898); //SETS ISP OF STAGE 1
SetThrusterMax0(th_main[0], 184752.84); //THRUST OF STAGE 1
SetThrusterLevel(th_main[1], 0); //SET LEVEL OF STAGE 2 TO ZERO AS STAGE 1 THRUSTER IS FIRING
SetCrossSections(_V(13.73, 17.84, 10.71)); //STAGE 1 + STAGE 2
SetPMI(_V(2.29,2.4, 1.79)); //STAGE 1 + STAGE 2
ATTACH_status = YES; //2ND STAGE IS ATTACHED
}
else if ((!GetAttachmentStatus(STAGE1)) && (STAGESELECTION == FIRSTSTAGE)) //2ND STAGE IS NOT ATTACHED TO 1ST STAGE

SetThrusterLevel(th_main[1], 0); //SET MAX THRUST OF STAGE 2 ALONE

if (STARTTIMER = START)
{
starttime = simt;
if (starttime > (starttime + 7))
{
EXTENDNOZZLE = EXTEND;//EXTEND CONE
}
}
}

ATTACH_status = NO; // NOT ATTACHED
}I have been able to get the timer to work.
There needs to be 2 of them. 7 seconds after separation the cone extends and then thruster is available. 94 seconds from release of ASE rcs is available

Ok need some help on the timer.
So if 1st stage is dettached
. kill both thrusters
. stage= separation
. get sim time
. end time = sim tim + 7
START timer;
If stage = seperation
if starter = start and sim time is greater than end time. 7 seconds have passed
now extend the cone.
if cone extended: stop timer
if cone is extended and stage is seperation now stage is second stage
The timer is what does NOT seem to work.
Alo I guess the IUS does that partial translational rcs (No backward thrust)

I got the ase to tilt

What is left?

Not sure. I got it to tilt and release the UIS. It can tilt to 0,29 or 58 degrees.
It needs to be able to go to -6° as well as that is the stowed angle for entry and landing following a successful deploy of the IUS.
gattispilot
Addon Developer
ok. I would thought 0 would be stored angle. Wouldn't that have the IUS tilted down?
So when would it go to 0?
So when would it go to 0?
0° is the stowed angle with the IUS, -6° is only used after the IUS is deployed and the ASE is clear.

Ok. now the ASE will tilt -6,0,29,58 degrees

Has the IUS/ASE the same scale as the Orbiter? Looks a little small...

Oh, I was thinking that was in SSU... carry on the good work then! :thumbup:

Yes that is the stock Atlantis. I don't have the SSU yet. So do I need 2 sets of attachments?
Well, you could move the attachment to the orbiter from the module to the cfg file. This way it would leave the important stuff alone in the module while the attachment to the orbiter can be cfg file dependent.
