Awesome, I love it. :) It'd be nice to see it on Soyuz TMA and perhaps on Buran and Kliper, too.

hey bobcat, do you plan to add the RD-0146(russian nuclear engine) to your engines pack?

RD-0146 isn't a nuclear engine. It's merely a nifty hydrolox motor with an extendable nozzle. Which BobCat's version lacks, making it a rather poor replica. CBBPs got this one right, though. RD-0410 was the Russian nuclear engine.

I've already told you like 5 times that RD-0146 doesn't have extendable nozzles. Please read this: http://www.lpre.de/resources/articles/AIAA-2006-4904_RD0146.pdf and stop spreading incorrect information.

Added poncutation and caps for you :) (coze it took me 2 or 3 minutes to understand what you wrote)

I understand his post and i found out that people that are not from english-speaking countries better understand bad grammar lol

soon im update American and Soviet pack. Im have big optimization plan , but all this need time.

And... texture reduction..totaly not.

nonono make a copy of all parts and reduce textures and put it in separate folder called Reduced Textures or....

I need to stop playing my favourite pack that's horror!

Russian Space Web seems to say otherwise. Also, this image: http://www.khrunichev.com/img/site/kvtk_sem.jpg is from Khrunichev, the RD-0146 developer. So I think that it does have the extendable nozzle. The paper you quoted seems to be from 2006, and since RD-0146 is still in development, I'd expect stuff like that to change (strangely, it does mention a "non-cooled nozzle section made of carbon composite material". That pretty much describes the movable section, only it seems to be fixed in this version).

RD 0146 IRL now no have extendable nozzle.

Maybe in future...

Maybe other modification based RD 0146

Maybe... in other life

Or maybe not...

In Soviet engine pack only RD 0146. No any extendable nozzle.

Well, maybe. Or maybe not. We'll see once the thing actually flies. Currently, about half the sources state it has such a nozzle, while the other half doesn't mention it. Perhaps it lost it when P&W backed out of the deal.

Anyway, great work on the monitors. I wonder if it's possible to simulate Neptune and the VZOR console using the RastarProp. It seems to be quite flexible in that regard.

OMG! You DO understand the difference between proposal and real hardware, right? The name RD-0146 was in the tender name, and as such there were multiple bids from different companies. The winner is KBHA who is actually building them now (not Khrunichev). The "non-cooled nozzle section made of carbon composite material" is fixed nozzle installed during integration into LV. Take a look at this picture:

On the left is what engine looks like as it leaves production facility. Note the lack of that carbon nozzle extension. On the right is what engine looks like when integrated into the stage. Do you see any extendable nozzle?

Looks like I'm a bit out of date regarding the project's progress. It indeed seems that it's the current version that doesn't have the extension. I've checked out KBKhA website (though I had to go to Russian version, then english one doesn't have this engine), it seems to confirm that. I don't know why Khrunichev's site isn't up to date on that one, it shows all KVTK variants with a rather obvious extendable nozzle.

EDIT: There's RD-0146 on the English version of the site, just not under "rocket engines" but under "advanced development". http://www.kbkha.ru/?p=8&cat=11∏=55

Anyway, it turns out that the closest thing to the earlier expandable-nozzle RD-0146 is one of the versions of RD-0126. http://www.kbkha.ru/?p=8&cat=12∏=53
