Idea Shuttle Fleet recompile for Orbiter 2016

[gattispilot]

So like this:

 

[MarkWatney2015]

Yeah, good catch. Looking at a high res picture of Intelsat, it looks like it has gold or yellow (my bet is gold) lines. Be interesting to find out why it changed.

Solar reflectivity might be the cause...for instance, the Opportunity's solar arrays are blue on Earth, but they appear rusty red on Mars

 

[gattispilot]

So I get this.

So now a technical question.
So the PAM motor is in the cradle and the cradle bar is attached to sat and pam.
But when the spin starts the that means that cradle bar is spinning also. But it had 2 guide slots.

Cradle bar and cradle and new pam2

Launch of Intelsat6

So here are the steps

So the cradle is removed.

But really need foot restraint to attach to the arm. With eva really can do this mission.

 

[Star Voyager]

Looking at the Media Resource Kit for 49, it says the cradle had a SuperZip system installed with canted springs. This leads me to believe that it was spin at separation (kind of like Leasat) due to the springs and not spun up beforehand like the PAM-Ds. The SSU guys might know more.

I think you might be interested in the following videos:

These are archived C-SPAN coverage (they pulled from NASA Select, so it has the usual NASA PAO commentary) of the 3rd EVA of STS-49 and covers everything from the rendezvous to the eventual IntelSat-VI F3 deploy.

So one thing on the launch. No spinning. So I will need to redo the dll. But not sure what happened to cradle bar? Also not sure what is sticking up on Intelsat6?

The Capture Bar was relocated from the bottom of Intelsat-VI F3 to the PKM so that when the spacecraft separated from the PKM, the Capture Bar remained with the PKM and didn't interfere with the operation of the Liquid Apogee Motors (LAMs).

 

[gattispilot]

Ok. So the bar remains with the (Perigee Kick Motor (PKM). So it seems that the assembly is spun but only on release? Not sure what speed? But a new dll may need to be made so that when release the rotate is added.

So a foot restraint need s to be able to attach to the rms and an eva guy to it.

 

[Star Voyager]

MRK says sep was .65 fps at .67 rpm.

 

[gattispilot]

Thanks. So for this when you release the satellite will start spinning at .7 rpm

This makes me wonder about the rest of the satellite launch.

So do the satellites spin in the cradle and then released or released and the rpm start?

It looks like the omni antenna is attached to the top on the satellite and I guess detach sometime?

 

[Star Voyager]

The canted springs spin it at the moment of separation. Here's the rest of the MRK.

 

[gattispilot]

Thanks

So for this a new dll will be needed. So that if SPIN is mentioned. When released the satellite will be spun at .7 rpm.

The satellite ,cradle bar, pam will be together. Then somehow the PAM and cradle get detached from the satellite.

eva guy at ASEM

[gattispilot]

Yes spin 3 doesn't rotate but start the spin on release. I think it is set for 30 rpm. Not sure if that is the correct value.

So it is a cheat as it should be slower but the PAM then speeds up to 30. Spin is 2rpm. while IntelSat6 is .7rpm

Any ideas?

from sts41 d
Ejection of the spacecraft from the Shuttle is initiated when locking pins at the four contact points are retracted. An explosive device then releases a spring that ejects the spacecraft in a "Frisbee" motion. This gives the satellite its separation velocity and gyroscopic stability during the 45 minute coast period between deployment and ignition of the perigee kick motor. The satellite separates from the Shuttle at a velocity of 0.7 m (1.5 ft.) per second and a spin rate of about two rpm. Deployment of the LEASAT satellite triggers an onboard automatic sequencer. The sequencer configures the satellite for firing of the solid propellant perigee motor. The telemetry, tracking and command antenna is deployed, attitude electronics, spacecraft power and telemetry are initialized, and the spacecraft spin rate is increased to 30 rpm.

so SPIN3 kinda works. But the direction is wrong and too fast

So I wonder if the PAMD and adapter need to be all black foil with the gold handrails?

[MarkWatney2015]

The replacement booster of Intelsat 603 is not a PAM-D, but an Orbus-21S (which is a derivative of the first stage of the IUS)....but it is similar to the way the PAM-D is ejected without spinning rapidly

---------- Post added at 03:06 PM ---------- Previous post was at 03:03 PM ----------

...Or rather, an IUS-like deployment in a right-angle degree

Why not?

 

[gattispilot]

So for this we still need a slower spring launch

So give her a try:
https://drive.google.com/open?id=13rNEgqApyWJPm6KQ2OXNYhctG9eyEyMq

SPIN0 in the scn tells it to use the slower rotation. PAyload 3 releases the sat.
The Orbus and sat are mainly just meshes further work need to be done to them.

 

[Marg]

A couple of textures missing (for example, golden foil for that pallet). But .scn itself worked. Amazing, that someone tried this mission...

 

[gattispilot]

It might be a while for me to fix as no power at house. Working on sts 61c

So here is the missing texture and cradle. https://drive.google.com/open?id=14eGr_o03zjlwGvMkSt0aT5-5ikt1aCsn

I wonder if the cradle should be more yellow than orange gold foil?

Working on the attachments.

To make this mission kinda work. The cradle bar needs to be attached to Intelsat and then rms get the sat to the cradle. Then sat and bar are attached to orbus.


new msl carrier

 

[pappy2]

I have found some pictures that will help you to have the exact details of the elements of the STS-49 mission hold.























Still very nice work thank you to you.

I can not grip the triangular structure that supports ASEM.
Can you remind me the key to make the astronaut appear in EVA.

 

[gattispilot]

Thanks. I will get to redoing the cradle and orbus. The ASEM I can add some texture but will not functional. I suppose it could but it would take a lot.


E opens the air lock and i think Shift E eva. But it is the MMU guy.


Yes not sure if the attachment in the center is correct. Will check it out.
