[WIP][1.8.x] SSTULabs - Low Part Count Solutions (Orbiters, Landers, Lifters) - Dev Thread [11-18-18]

I can't wait to use this. Sadly, I'll have to wait till 1.1. :( Others have confirmed the same issues I have with 1.0.5. Their 64 bit hack doesn't work. Awesome mounts, can't to use them. See you guys (hopefully) on December 25th. :D

[_Augustus_]

Just an idea: Why do you use your own RS-25? Why not just use the stock one?

I PM'ed Shadowmage asking the very same thing before he released his RS-25, he noted that stock would be weaker (and it is) and his would include a few more bits like pumbling

Ouch, that is no good. I really do wish they would have just held out and finished off 1.1 (rather than doing all the prep/experimentals work on 1.05), as the community needs 64-bit far more than it needed whatever changes came with 1.05. Some of them were good changes, but extremely minor compared to the improvements we could have had.

Pretty much that. Less detailed (though, that could be a good thing), smaller (e.g. not 64% scale), and less powerful. Also continues the stock inaccuracies regarding engine geometry, with its complete lack of upper-end/combustion chamber, and poor representation of the gimbal mechanics (it doesn't pivot in the right place, or even close to it; the pivot should be at the top of the MCC, NOT halfway down the bell).

Nothing stopping you from making your own engine clusters using the stock KS-25 though. Could pre-arrange a 3-engine cluster for shuttle use even.

I used to be hooked on 64 bit KSP, but got from my addiction (cold turkey), by using OpenGL, and judiciously going through each and every one of my mods, clipping out stuff I did not need (some mods were severely clipped, others were not so clipped). Happily, I have not clipped anything from SSTU except for the Ship core series C (sci-fi ships and accessories). I use over 80+ mods, which include 6.4k mod, OPM, EVE and host load of others, and I do not have any issues with game crashes due to memory overload.

I cannot live without my SSTU...your landers and command modules, and their accessories are an absolute must for my game.

Now, when 1.1 finally arrives, all of my mods will be reinstalled, happily with all of their little bits intact ;).

Cheers!

Glad you are finding some use for the mod :)

Yes, the Series-C stuff is a bit of an outlier; one of my first sets of models (well, second actually), so the quality is a bit lacking. Also the overall function is not quite up to the same level as the rest of my part. I already have it scheduled for a refresh/rebuild, but it will be awhile before I can get around to it (likely sometime in like Feb. of 2016).




General question --

How does the thrust feel on the RL10 engines?

They seem a bit... underwhelming to me; though, it really is a fairly tiny engine IRL. Still thinking I might do another 10-20% buff on the LH2 engines thrust across the board. Suppose we'll see where the J-2 fits in; really the RL10 is supposed to be the payload-delivery engine, whereas the J-2 would be for the 2n'd stage/most of the orbital insertion.

[Shadowmage]

J-2 texture is progressing nicely. Probably about 1/2 to 3/4 done at this point --

[VenomousRequiem]

Mmmmm...

[Shadowmage]

Near-finished textures for J-2, only a few minor touch ups to do (seam removal/cleanup, double checking things):

J2X is on the list. F1 and F1B. Would the F1A (which was never built) have looked any different from the regular F1?

I don't have Shadowmage's list in front of me, but I don't recall them being on it.

When can we expect RS-68s to reappear? I want to recreate an Ares V.

I really like the concept behind this. I like mods using real NASA style, but with black and white theme suitable for KSP :)

while HG-3 did look a lot different than both J-2 and RS-25 and I agree that it would be a good addition if Shadowmage decides to make it, I don't see a reason to make a J-2S and a F-1A models, as they pretty much look the same

even Vinci I see no reason to make, as it looks really close to the RL-10B-2

are you a rocket engineer or something? you find a lot of cool documents :D

[Shadowmage]

For reference, here is the most recent list of engine stats that I have. Many engines on this list will be being made, but perhaps not every one.

[quote name='blowfish']J2X is on the list. F1 and F1B. Would the F1A (which was never built) have looked any different from the regular F1?[/QUOTE]

As far as I know the F1A was mostly plumbing/tubos/internal/mass differences. Should have looked (mostly) the same externally.

[quote name='_Augustus_']Are you gonna do the J2S and J2X?

What about F1A and HG-3?[/QUOTE]

HG-3 - don't think I've heard of it before, at least I don't have any references to it.

J-2S - the changes between the J-2 and J-2S were nothing that would require a separate model (I believe my model already incorporates parts from both the J-2 an J-2S, due to lack of complete references for either model). You are welcome to make a MM patch to add a variant if you would like, though I have no idea what the stats would be.

J-2X has vastly different geometry, different bell, and very different stats. It will be done as a completely separate engine. Probably not this week, as I've still got mounts to do and a heapload of bugfixing.



[quote name='davidy12']When can we expect RS-68s to reappear? I want to recreate an Ares V.[/QUOTE]

Well, the only engines I have left that have been started are the J-2X and RS-68. So, won't be more than a couple of weeks/month. Should definitely have it done before KSP 1.1

Sweet, will give it a look over. Awesome references :)

From a brief look, yes, the F-1A looks almost exactly like the F-1.

[davidy12]

The HG-3 was an engine sort of in between the J-2 and RS-25. It was used on some proposed Saturn V models. You can go check it out on Astronautix.

Also, what I'd like to see an substitute to the Apollo CSM in the distant future (maybe sometime next summer...). Orion just doesn't fit with it.

[Shadowmage]

Sadly there is no -actual- information on the HG-3, as it was never produced or even progressed past the 'idea' stage. No schematics, no pics, nothing. There are a few 'stats' listed, but those do me no good without the rest of the information.

So, no, I will not be making an HG-3, at least as long as I cannot locate reliable and detailed information on it. At the very minimum I need some schematics or pics.

Google search on HG-3 Rocket engine -- note the complete lack of any actual images or info on an HG-3 engine.

[davidy12]

Yeah, I wasn't planning on you to make one. If you want to make a Saturn V/260, just scale down the thrust of an RS-25. Edited November 17, 2015 by davidy12

[blowfish]

Guys, I think Shadowmage has enough to do already without trying to pile on a bunch of historical almost-the-same-as-this-one-but-not-quite engine variants with only sketchy references to performance and apperance. The engine list is solid and quite extensive as it is. Edited November 17, 2015 by blowfish

[Shadowmage]

Slightly updated S-IVB mount geometry; now with more greeble!

(stringers/etc will be added as part of the normal map/texture)

Quite.

I likely do have enough engine designs for the time being. Heck, would likely take me another 6 months just to get done the ones I have planned.

Currently it is looking like the the 'small' lifter engine will be either an H-1, Merlin-1, or S-3/LR-79 (precursor to H-1). Likely will end up doing most/all of those eventually (really only lacking good info on the Merlin). They all end up with a scaled bell diameter of < 1m, so should be acceptable for 1.25m use.

0.625m engines will likey be filled in by 'thrusters' such as the AJ-10 series (apollo SM, Shuttle-OMS, Orion-SM-main engine). Perhaps some of the old 'missile' motors as well; I'll see when I get there :) Edited November 17, 2015 by Shadowmage

Here's some post-Apollo engine proposals side-by-side.

[IMG]http://www.astronautix.com/nails/s/satupeng.jpg[/IMG]

The HG-3 would have a thrust of 1400.7 KN. More data is right there.

Also maybe do the M1?

[IMG]http://www.astronautix.com/graphics/m/m1engine.jpg[/IMG]

This thing was MASSIVE. 6670 KN of thrust at sea level. Despite numerous engines being built and tested, not a lot of info is available.

[IMG]http://forum.nasaspaceflight.com/index.php?action=dlattach;topic=31401.0;attach=896896;image[/IMG]

That's one of the Nova rockets' (Not to be confused with the Saturn C8) second stages.

The M1 looked like a really big single-nozzle LR-87. There is some more info (and images) on some other space forums.
