Request Any SLS and Orion MPCV in development?

[gattispilot]

Ok. On the scenario. The scenario has the LAS fire unpon the core fuel depletion. But it should separate off. Then 20 seconds the fairing come off.

After the LAS fuel is depeleted is comes off. But comes thru the ship and the panel don't come off

The CS should not run to depletion, this is bad. There's always some propellant left to ensure that the turbo-pumps doesn't run out of propellant. Running the TPs dry is very bad there's no resistance which means that the RPM will go to pretty much infinity which means vehicle destruction.

That's why all turbo-pump equipped engines have so called Low Level Cut-Off (LLCO) sensors installed somewhere on the stage, either in the feedlines or the tanks themselves. When a preset amount of them show DRY that sends a signal to the computers to immediately shut down the engines. These sensors are checked out during the launch countdown to ensure they're in proper working order. Depending on what the Launch Commit Criteria (LCC) says, a failure in one of the sensors could mean an immediate scrub for troubleshooting.

Post-Columbia, the shuttle had a lot of trouble with its LLCO sensors which was later traced to a bad design of a feed-through connector on the External Tank.

IS the CS the core? But in velcro I think that is out it separates. When the stage runs out of fuel the next starts

 

[Astro SG Wise]

So the core stage makes it all the way to LEO? I thought the core stage separated and the upper stage completed the orbit insertion, like an S-4b.

Then wouldn't the core stage have to burn a little to de-orbit?

Yes. It at least can make it. It is powerful enough to. I believe that it might not purposely, so than the second stage can complete it, and the core stage burn up in the atmosphere. Someone acknowledge me?

Foam.

Really? I thought it wasn't foam. It would have lots and lots of problems like shuttle had with foam, right?

The only problem with the foam was due to the orbiter being side-mounted, directly in the path for any debris. SLS/Orion will not have this problem as it is top-mounted, out of the way of any debris.

 

[Astro SG Wise]

BUt I was looking at that spaceport and saw this:
"Actual SLS Vehicles will not be Painted White."

So do I need to change the core?

No. Really, I think spaceport is wrong. All, and I mean ALL, of the animations for SLS are white. I think it would be incorrect, from all that I know. Even so, I wouldn't like it as much because it would look to much like Ares V. Space Launch System is more like Saturn V than Ares.

The usage of the Velcro LAS has to have the same technique as in Velcro Saturns in similarity to the AMSO related scenarios.

Thank you. I thought of that, but then again, foam still seems to thin and weak. Do they use it because of the weight?

 

[ISProgram]

No. Really, I think spaceport is wrong. All, and I mean ALL, of the animations for SLS are white. I think it would be incorrect, from all that I know. Even so, I wouldn't like it as much because it would look to much like Ares V. Space Launch System is more like Saturn V than Ares.

Some documents note that it will be ET-colored. I'll try to find them if anyone wants to se them.

And you're right about it bring more Saturn than Ares. Frankly, if they put paint on it, it would most likely be for visual tracking purposes during ascent, like Saturn.

However, I heard some talk a while back that the reason the SLS looks like Saturn was for PR purposes. Whereupon NASA wanted it to be clear that the Ares were successors to the shuttle, by making them look like them, after the fall of Constellation, NASA wanted to make it clear the SLS was to bring back the Saturn glory days, hence why it looks like Saturn.

That being said, NASA, please paint SLS.

Yes. The external insulation on the only largest cryogenic stage before the ET, the S-II, was very problematic. First it was phenolic honeycomb, then they switched to spray-on. Here's a somewhat in-depth article.

I can make a white and orange texture. But I need to get to work.

Here just 1 panel comes off in 20 seconds

 

[Astro SG Wise]

I would start with orange, but that is just me.

The 2 cargo versions use the same core. They fly good. But the crew version doesn't yet

 

[Astro SG Wise]

I agree with ISProgram. The look of the new Space Launch System is much "cooler", and it reminds everyone of the space race history. I went to EAA air venture, and NASA had inflatable SLS rockets with Saturn V designs. They are defiantly promoting it that way. You should make it like that. NASA has been promoting the new designs for years now, and in 2017 they are planning Exploration Mission 1. I don't think they are going to change their plans just now.

 

[gattispilot]

I have run into a issue on the saved state.
Here is the craft after 1st stage separates. The panels and LAS fly off.
https://dl.dropboxusercontent.com/u/71242599/SLSSEPARIONorion.jpg

then I exit and restart no Orion. It is orbiting the sun. I emailed the velcro rockets author about it.

https://dl.dropboxusercontent.com/u/71242599/SLSSEPARION.jpg

I got the same results when I tried a saved state with the acrgo version and my ARV?

Any one else tried the 2 cargo versions?

 

[Astro SG Wise]

Pictures look great. I have no clue as to why Orion disappears though. I get things like that alot.

 

[gattispilot]

I know why? The saved state is messing up. If I start the scenario The Orion is there. I exit and restart She is not there. I noticed the thruster level is not being saved either. It maybe a Velcro rocket issue.

If you email me I can send you the files and see it for yourself.

Here is the latest SLS cargo and Orion version. The space below the Orion can hold a MLM.

But I noticed something on the tower. The Crew Access is too low.

Hey John is it possible to be able to adjust the crew access to fit the capsule?

 

[4throck]

The Crew Access is too low.

Yes, and that is more noticeable than a lowered rocket stack. So I'd lower the rocket, even if it goes a bit under the launch platform. Sure, not perfect, but less noticeable than a crew access..
