Project Space Launch System

Actually, the interstage is still the same height. The core is increased to allow for more fuel to be held. And I am talking about the first stage engines. I have got some small amount of work done on it. I don't know how this happened, but I forget most of what I learned over the summer about it. The problem I am having is to make the bottom part of the stage and all the curves.

This can't be true unless you're talking about increased diameter.

And the correct term is "intertank". An interstage is a structure between two stages, while an intertank is a structure between two propellant tanks(fuel/oxidizer).

And I have been following SLS pretty closely since it was announced in September last year and I have never heard of this "extended core" version.

So could you post the presentation and the page number which discusses the extended core version.

 

[Felipi1205]

Me too! I never heard about a extended core.

Here are the two links.

They are what I have right now.

Nothing in the NASA document which deals with the boosters, not the core stage.

Also nothing on the SLR page. I think you have misunderstood the SLS core stage. It is already stretched to deal with the length of the Five Segment Booster(FSB).

The attachments are like on the Space Shuttle, aft and forward. The aft attachment is on the core stage Thrust Structure/LH2 tank aft dome while the forward attachment is on the intertank.

Okay DaveS, thanks for that, and me making a very bad mistake on my part.

 

[Capt_hensley]

I don't know if it requires evolved boosters.

I meant that they have evolved from STS to SLS, and that they sould be either rocket fuel type unlike STS solids only. But yes I'm sure with the upper stage 130mT is a rightious goal.

SLS interests me greatly I need it's advanced capacity to help get Gateway Station into GEO orbit. The heaviest object is 10mT, but it needs to go all the way to GEO, non-stop. SLS is the bigest available ticket to ride.

Also, I suggest that whatever you do, don't give it that ghastly black-and-white Saturn V paintjob. It's only there for PR, there doesn't seem to be any technical reason for a flight vehicle to be painted that way.

This is the answer directly from @NASA_SLS:

@DaveS_Orbiter That is what we anticipate now, but as the vehicle evolves, so might the paint scheme.

 

[T.Neo]

If that's what they 'anticipate', fine... but why? Why paint the vehicle white when it doesn't need to be? Have we gotten to the point where PR and paintjobs are more important than technical issues such as cost reduction, streamlining manufacturing, and reducing mass?

At least they leave the possibility of weasling out of the paintjob at some point in future, should the PR value be deemed to be insufficient to justify it.

To put it bluntly, it is a stupid paintscheme for the vehicle...

I am putting this project on standby for a while, till my skills get better at Wings3D.
