The above looks like the rocket in question.
Zak claims it is supposed to have a liftoff mass of 2400 tons vs. 810 tons for the Angara 5V. The new design can
deliver 80 tons while the Angara 5V can deliver about 40 tons. Something is off.
The RD-171 has basically four times the thrust of the RD-191 used by the Angara modules. In this proposed
rocket by Energiya the four boosters and first core stage all have RD-171 engines. Faster burn allows less fuel
mass to be carried and increases the payload to total mass ratio. But supposedly we have a degradation of the
ratio. I think Energiya can tune the size of the modules with RD-171 engines to achieve the same payload
ratio as the Angara 5V.
Zak always bitches about how new Russian rocket designs can never be delivered to the far eastern Vostochny
cosmodrome because they are too wide for railway tunnels. I am quite sure I recall him claiming Angara stages
were too big. Well, Energiya can shrink down the stage diameter to fit the tunnels and take advantage for the
4X faster burn of the RD-171 to get a heavy launcher with a mass of 1600-1700 tons that can deliver 80 tons to
In the future don't be surprised to hear more bitching from @Zak .
He lives in United States ^^ ,behaves like a Liberal , demonizing Putin for all, and he shows all the symptoms of every other
corrupted anti Russian NGO paid TROLL , to downgrade and downplay Russia space program. So for example If Russia do a mission to Moon or Mars.. he could be hired to debunk it.. and claim
the travel was a hoax and never happened. or that the rocket "exploded" for malfunction
and that Russia shows only movie.
His website could become for example the portal of "space news" in case Russia try
a manned landing in moon or mars.. So that if for example Russia spend billions dollars
going to another planet. he could be useful for the west,to discredit Russia. This is not
conspiracy .. already he is doing such things.. with the Exo MArs mission ,claimed the Russian rocket failed and exploded while Russia government deny it.

This is the biggest news in rocketry since the USSR made oxidizer rich staged combustion rocket engines that the USA thought were
impossible (no US alloy could handle the heat). That was an epic historic event and so this one.
But of course all we will hear about is Putin, Putin, Putin, hackers, Putin, aggression, Putin, blah, blah.
...Can you go in depth about the full potential of PDE's? I admit I'm not the most informed on this subject. BTW the 2020's will be a real watershed moment with 3-D printing, scramjet engines, PDE's, high-energy fuel, and laser-fusion superalloy aluminum and nickel powders!

Sounds like this could be related to the Fenix project, or an evolution of the Fenix concept to maintain the usefulness of the Baikonur infrastructure into the future.
Russia charts new path to super rocket
Good points, but I don't belive that you can fit 4x RD-191 in a 4.1m diameter core (RD-192 is the proposed methalox version).Rmf wrote:just as i was predicting its a great rocket proposal. simmilar to zenit but with some differences , they increased size of 1st stage which is good , but choice of engines is not good , it should use same engines from angara rd-192, but 4. that way you have universal single engine for evey launcher. also only kerosine and oxygen is used in all stages which is good.
i guess railroad is good for transport up to novosibisk in central siberia , from there its not very far , 3000km , they could transport it by plane an-225 ,2 rockets - 1 inside and 1 on its back to vostochny.
but other thing strikes me , 2024? Holy damn , what has become of the Russian space program? its ruined??
Engines are ready; fuel tank factory is ready; launch facilities are basically ready; command and control is ready; why the hell would take 7+ years?
Rmf wrote:ukraine was producing tanks and integration but engines were made in russia. never the less its moot point , when russia has rd-191 , my mistake not rd-192. its 1,92 MegaNewtn thrust which is compact and derivative of rd-171 itself. it can fit . it has less weight 4 combined then rd-171. and more slightly thrust which they want. that way you have mass production what they wanted all along....
see how stupid soyuz launch pad is in vostochny now>? billions blown for nothing.... instead angara and sunkar launch pads should have been built.you cant built launch pad for angara + sunkar all in 1. sunkar is 4 times larger.
sunkar should be built in 4 years max , and launch pad too. they have zenit plans,engines, manufacture big tanks , everything... 7 years and with more delays it will probably be 10 years= massive coruption and siphoning of scarse resourses.
also look how they improved sunkar and rectify flaws from zenit , increase in fuel (and weight) of 9% but payload increase in 25%.
