[0.23.5] Realism Overhaul: ROv5.2 + Modlist for RSS 6/30/14

[SFJackBauer]

Ok, I will set then the vacuum thrust at min. throttle (no need for you guys to mess with the configs ), but remember this means the value will not be reflecting what happens inside atmosphere.

[AbeS]

I don't tend to throttle in atmo anyways

[NathanKell]

SFJackBauer, I think you mean "I will set minThrust to maxThrust * min_throttle_percent"

[SRFirefox]

The Bobcat Soviet engines' included configs are out of date and/or incorrectly written, so I wrote up a fix for my install, since I love the Energyia and Soyuz launch vehicles. I've included guesstimates tech levels (ie. 4 for the Energia engines, 7 for the RD-0146), adjusted oxidizer-fuel ratios where necessary and where I could get the info, and even added the only Methane/LOX configs I know to exist to the RD-0120 and RD-0146, as they both had the configuration proposed but not implemented. I also tweaked the mass on the RD-171, though Bobcat's could just as easily be correct as I. These configurations are designed to work without modifying the engines' original files. Finally, I've put the full real gimbal ranges of the engines that I've been able to find, but be aware the RD-171 and it's derivatives have large ranges, up to 8 degrees.

Also, Having a 4m capsule and 2.5m crew cans seemed silly, so here's a rescale of the lab and crew can modules to size and mass them for 4m diameter parts. I also increased the amount of electricity used for resetting the SCIENCE from the lab, since it is measured differently now.

Has there been a release or pre-release yet that includes up-scaling of all the B9 HL parts?

[NathanKell]

SFJackBauer's latest RealEngines package does. Sadly RF does not yet fully support SABREs (as you know...)

[SFJackBauer]

@SRFirefox

Bobcat Soviet engines are already supported in the RealEngines configs (see listing in this post).

That said, I would appreciate if you could review any discrepancies from the data I have (minus the gimbal range, its being reviewed for next release). Bear in mind though, that the masses in your configs are too low as, most of the time, the mass cited in literature account only for the engine itself, and not for the thrust structure (which has been accounted for in the RealEngines configs).

[NathanKell]

SRFirefox: thanks for the rescales. Nabbed!

Re: Russian engines. They do include thrust structure mass in their mass. Which makes the NK-33 and 43 even more impressive, holy smokes.

Note that the original ModularEngineConfigs figures for the engines were pulled from here when I did them up, IIRC.

[jrandom]

Oh wait, RealEngines isn't incorporated into RealismOverhaul yet? Ack! I'd better reinstall that before loading up my primary savegame!

Hang on a tic... my current RealismOverhaul has a real_engines_rescale.cfg and real_engines_stats.cfg... can I copy over just the B9 rescale from RealEngines and disable the one in RO?

[NathanKell]

jrandom: the ROprev3 in the RF thread has it, but not the rest. ROv3 (which I am currently working on) will have it all.

Yes, you can (for now).

Speaking of ROv3--do you have an updated copy of your AdditionalConfigs? 404 now, what I have is as of 12/15/2013. (I'm merging much of it in).

[SFJackBauer]

Re: Russian engines. They do include thrust structure mass in their mass. Which makes the NK-33 and 43 even more impressive, holy smokes.

Some do, some don't (RD-170 does, NK-33 don't).

[jrandom]

do you have an updated copy of your AdditionalConfigs? 404 now, what I have is as of 12/15/2013. (I'm merging much of it in).

I did some folder-shuffling. This is the latest of everything I'm currently running in it (previous versions on dropbox had anything I didn't author removed), including the custom FASA that's been modified for some BigG parts (and those need a serious numbers check), a Fustek rescale I picked up somewhere, any other various bits and pieces. Let me know what you integrate so I can remove them from Additional Configs at the next release of RO!

I'll have a go at it in the morning, but do note the RD-0120CH and RD-0146U configurations for burning LCH4/LOX. While not of particular practical value at this point in the mod, its still one more thing to add, especially if realistic ISRU on Duna/Mars becomes a thing.

[Guest]

Once money is added, methane will be a cheap-ish, but high-tech RP-1 alternative. You'll still want to use Kerolox for your highest performance rockets (or Syntlox, at that point), but for a cheap, frequently launched LKO rocket methane will be the fuel to go.

[jrandom]

Looks like we have a slight discrepancy between the RealEngine B9 rescale and the RO version...

[NathanKell]

jrandom: I wasn't aware that RO had any B9 scaling on its own, but apparently it does. Heh. I'll deal, I think by matching RealEngines.

SRFirefox, Dragon01: LCH4 yields a rather higher specific impulse than kerosene, actually. Think 375 vs 350 vac Isp for chemical. (And it's the big winner for NTR, sweet spot between low molecular mass and high density).

[Flopasaurus]

Okay, so after a few days of messing with the mods, I finally got it all to work together, however I do not have the real fuels in my game, I have the modular fuel tanks mod installed, without it the game doesn't even launch, but I do not have any of the fuels in the tanks that the actual engines use, so I can't go anywhere.

Anyone know what my problem is?

[NathanKell]

You need RealFuels, not MFT. Note the top of the MFT post, where it says MFS has been split. You want the RealFuels version.

[dlrk]

How could I change the Mk1-2 pod so that the top attach point is a standard 2m size?

[dlrk]

I resized the shielded port to fit by setting the 3 model scales to 1.5 and the rescale factor to 1

[jrandom]

How could I change the Mk1-2 pod so that the top attach point is a standard 2m size?

I thought the top already was 2 meters, with the bottom at 4 meters.

[NathanKell]

Pods are slightly differently sized--there was much discussion of this in the RealChutes thread. The tops of the pods are like only about 80-90% as wide as they "should" be for their stack size. Bases...Mk1 base is slightly wider than 2m, Mk1-2 base is about 3.9m. Anyhow...

[Scripto23]

So I've been trying to figure out why my rockets have been spinning out of control in vacuum and I've finally figured out that the Mk1-2 pod has a CoM that is off center. Is this intentional? I remember reading something about an off center CoM for use as a lifting body while reentering atmosphere, but this makes designing stable rockets quite difficult.

edit: just took a quick look at the code and found the line CoM offset line, so I guess this is meant to be there.

Edited January 2, 2014 by Scripto23

[NathanKell]

Yup. I need to modify the DRE decouplers to have opposite offset mass such that it all works out.

[ferram4]

That pod also needs to have slightly more offset. It only gets ~8 degrees angle of attack and it should have ~15. I'd say shifting it ~0.3m - 0.5m more should make it right.
