As the old guys who work for $100 a month die off or retire, the Russians are going to have an ever more difficult job of maintaining their current level of development, let alone expand into heavy lift boosters.
Yenisei-5What is it? An Energia killer with four Zenit boosters around a 4.1 m core powered by three RD-0120 engines from the Energia. It surpasses even the Saturn V in payload to orbit and rivals it as a lunar launcher.
Thanks for the overview... Some interesting ideas. But it is all powerpoint fantasies. The Angara 7 has the most likelihood of happening by a significant margin, but it is still not very likely in the near future.I did spot an error, though:QuoteYenisei-5What is it?

The core is not 4.1 m - it does not match the images nor does it seem plausible with the performance suggested.EDIT: And I don't understand how "Yenisei-5" would have more payload capacity than Energia. It really is just a modernized Energia but with one fewer RD-0120 engine, right? So how does that add up?
Isn't it funny that a great majority of this forum consists of discussing NASA powerpoints or 3D renderings that never get off the ground, but somehow discussing russian powerpoints and 3D renderings is looked down upon?What gives?

That's one thing Russia's economic revival has let it do besides increasing Roscosmos' budget. As for the heavy boosters, the only thing standing in the way of the Angara 7 is a new pad and developing a new 3.8 m core. That is something the Russians have the resources and skill to do still. Now the biggest Angara 7 might only launch 41 mt if it's got a kerolox core, but that's vastly more than what their Protons can launch today. Whether it qualifies as "heavy lift" depends on how one defines that category of launcher.
Another point about the 4.1 m diameter - it seems like a physical impossibility to squeeze 3 RD-0120 engines onto such a core. It must be a typo.

If you don't think Anatoly Zak of Russiaspaceweb's info is correct on the Yenisei-5 can be correct, you can go to his website and contact him about it. I'm only posting what Anatoly has on the vehicle, and what he has suggests the Yenisei's central core is 4.1 m in diameter and lifts 125 mt to LEO. I'm aware the images don't look right for those figures, but that's what Anatoly Zak has posted. As for how it does it, well it is a much narrower core than the Energia yet the vehicle's total mass is quite similar. The reduced drag losses can't hurt.
"The use of liquid hydrogen on the core stage as oppose to kerosene fuel would sharply increase the capability of the proposed launch vehicle, enabling it to deliver 125 tons to the low Earth orbit. "

Rather its Khurunichev themselves.
Yenisei-5 and Amur-5 (another name for the biggest Angara) as envisioned by Khurunichev (Got these from NSF and NK forum):EDIT: so hkultala, as you can clearly see, its not Anatoly Zak who's making up 125mt to LEO for yenisei-5. Rather its Khurunichev themselves.
