Project Orion MPCV

[pclaurent]

Here is my version of Orion+EUS launch scenario and config files, to install on top of SLS2016. Due to the diameter of the EUS, I wasn't able to use the top fairing (with NASA logo). But Orion is now correctly attached to the EUS. See included scenario for instructions.

So I get this with your set up:

With my setup I get this:

I wish I could use your model because it is definitely nicer. The question is: what does it look like when Orion+EUS are in orbit? When I tried, Orion was away from the EUS. So the only way I found to get both modules attached was to put Orion CM directly on top of the conic fairing. That explains the other external design...

 

[barrygolden]

The deep space hab would be place at the L1 site.

 

[gattispilot]

Oh I see. So is there a structure that should be there?

What if the fairings that go between didn't fall off.
I had them labeled as FAIRING. I that the Orion Nasa labeled as Booster_7. IF you reverse that the nasa Fairing fall off and the other stay. Not sure then if both are boosters to tell them to fall off?

SLS Support to Gattis & SLS Video

Gattis to have the scenario ready for launch with propellant fuel loaded open the scenario file as text and scroll down to SLS:Multistage2015 where you see PRPLEVEL set it to say

  PRPLEVEL 0:1.000000 1:1.000000 2:1.000000 3:1.000000 4:1.000000 5:1.000000 6:1.000000 7:1.000000

Here is a short video of all the great work going on in Orbiter 2016 and the SLS Orion & Cargo version, thanks guys

outstanding video

Very impressive video PDF,thanks for sharing it.

Good video but... Holy God, why... why that crappy dance/electronic music?

;-)

 

[barrygolden]

I still enjoy seeing what could happen. as for the music not sure if George Strait has a song that would work for that.

I wish some one would look at 4th rocks Altair and get it working in 2016 and take Altair 1 and use like an Apollo 5 flight. A test of the SLS and Altair. That would make a good first SLS flight.

Also need help or advice with the skylab 1973 in 2010, just got new computer and the Saturn 5launches but unable to deploy the sun shades or solar wing. I did press the right keys. Also there is a video about skylab on you tube and it shows 2 eva guys can't seem to find them as well

Well what doesn't the Altair do? Email me. I might can take a look.

We are working on the fairing issue also

Thanks for this. After being away from Orbiter for a few years I watched, think it was something like "Extreme Engineering" on Yesterday that had a lot about Orion. The chutes, the new friction welding process and a lot more. So this was a great addon to start back with ! :tiphat:

My Orion addon gallery here.

 

[barrygolden]

Welcome back. I have been a fan of orbiter for awhile as well and with the retirement of shuttle this could be the next big addon for 2016.

 

[gattispilot]

So What if on the SLS we make the Universal Stage Adapter an Interface. I am not sure if it 1 piece or 2 or 4?

That way when the EUS runs out of fuel it will seperate and the Orion will be free?

 

[francisdrake]

You mean like this?

I put 3 attachment points to the EUS. The first is on the top of the universal spacecraft adapter, carrying the Orion. The Orion is separated first, using the [J] key.

I guess the spacecraft adapter will be one piece only. It has to carry the weight of the Orion during launch. Splitting it into pieces would weaken the shell.

The two other attachment points are at the spacecraft interface plane, at the bottom of the universal stage adapter. Once the Orion is clear of the EUS, the universal adapter (white cone) can be separated, and after this a secondary payload (here a Cygnus-type mini hab). All these events are activated by the [J] key.

Will check if there are no unwanted side effects. If all is well, I will include this in the next release.

 

[barrygolden]

you guys ought to get with gattis to add the HGA from his JWST to MPCV. this still a super addon

 

[francisdrake]

The new version 14 can be downloaded from the first page.

What's new?
- SLS upper stage defaults to EUS.
- Universal payload adapter allows a secondary payload.
- Deep space habitat is in Moon orbit.
- Solar electric Mars ship is available.
- Scenario files now have preview pics.

The deep space habitat and the solar electric ship are config-file vessels only, to have docking targets for the Orion. These vessels have basic RCS thrusters. The solar electric ship has an (overpowered) ion drive, in case someone wants to try a Mars mission.

Perhaps I've missed something, but it seems to me that the Orange-SLS is not powerful enough to put Orion+EUS in LEO (EM-2 mission). No problem with EM-1 and the lighter ICPS, but EUS seems too heavy for that. If someone has succeeded, is it possible to have a typical launch profile with some values for Alt + inclination during launch? And is there any plan for an autopilot (for lazy people like me )?

 

[francisdrake]

... it seems to me that the Orange-SLS is not powerful enough to put Orion+EUS in LEO

This was already a topic a little earlier. The EUS is indeed quite heavy and needs a different ascent profile:

Because of the higher mass of the EUS the inital acceleration is slower. So wait a little longer before tipping over after launch, and aim for a higher orbit, like 300 km.

Just before burnout of the first stage pull up to +30° to build up positve vertical speed (+1000 m/s). This will help to gain speed with the EUS, rather than fighting gravity with this stage when fully fueled.

Have the Surface MFD open and watch for the vertical speed. If it approaches 0, pull the EUS up +30 or +40°, to keep the vertical acceleration around zero.

The Block 1B SLS could indeed stand more powerfull boosters to ease ascent, but I am not sure if this planned.

For an autopilot you could give the Launch MFD a try (but I don't know if it works for multistage launchers).

Try to use ms2015... it was 3 years of work for the autopilot for multistage launchers, it may solve this
