Time for more weeding.... the new batch of weeds are not worth keeping however and will not be moved.... simply be deleted... like the trash it is.
Done.
I am happy with that.
Any concerns or people upset by all means feel free to send me a private message and we can discuss, but comments and complaints or further arguments and insults are off topic and will simply be deleted... continual posts of abuse/complaints/BS and off topic rubbish will lead to warnings and temporary bans... or worse.
Fire tests of the engine for the modernized "Angara" are scheduled for 2022
MOSCOW, December 31. / TASS /. Fire tests of the first sample of the RD-191M engine, which is intended for the Angara-A5M launch vehicle, will start next year. This is stated in the message of Roskosmos, distributed on Friday.
"The design documentation for the RD-191M has been prepared, including in the form of an electronic 3D model. Fire tests of the first instance of the RD-191M engine are scheduled for 2022," the statement says.
As specified in the state corporation, the RD-191M differs from the RD-191 in terms of thrust level. "It is boosted by 10%. In this regard, a number of structural elements have changed," added the Roskosmos.
The modernized Angara-A5M is designed for launches from the Vostochny cosmodrome. It is planned to use it to launch new manned spacecraft "Eagle".
In May, the director general of the Khrunichev Center, Aleksey Varochko, told TASS that the assembly of the first flight prototype of the Angara-A5M launch vehicle, designed to launch the manned spacecraft Orel, would begin in 2023.
This 10% figure is spectacular. We are talking about a derivative of the RD-170 which was advanced in 1985 and optimized since then. That they still can squeeze out this much performance is nothing to sneeze at.

MOSCOW, 25 January. /TASS/. The Angara-NZh, which is a full-size model of the heavy Angara-A5, will be delivered to the Vostochny cosmodrome in the summer. This was announced by the Director General of Roscosmos Dmitry Rogozin on Tuesday.
Angara-NZh will appear on Vostochny in August of this year, and it will be located in the technical complex," Rogozin said during a plenary session as part of the XLVI Academic Lectures on Cosmonautics in memory of S.P. Korolev (Royal Readings)
As TASS was specified in the press service of Roscosmos, the Angara-NZh is a full-size model of the Angara-A5 for conducting complex ground tests.
Angara is a family of Russian launch vehicles. Universal rocket blocks "Angara" are manufactured at the Omsk software "Polyot" (part of the Khrunichev Center of the State Corporation "Roskosmos"). The launches of the heavy Angara took place on December 23, 2014, December 14, 2020 and December 27, 2021 from the Plesetsk cosmodrome. For the first time, the Angara-A5 rocket will be launched from the Vostochny Cosmodrome at the end of 2023.
To reduce the cost of flights in order not to remain in the tail of the space race is a task without the solution of which there are no prospects. Reusing the spent stages of the launch vehicle is an extremely necessary step. Roscosmos"began to work on a version of the "Angara" with returnable blocks of the first stage. Roscosmos is working on the possibility of creating a version of the Angara rocket with a return package of five blocks of the first stage, Dmitry Rogozin, general director of the state corporation, said on Tuesday. Angara launch vehicle. Roscosmos Photos "We have one idea, which is that it would be possible to look at the possibility of working on the Angara from the point of view of the returnability of the first stage package, without splitting it, without scattering it into separate universal missile modules," he said at the plenary session of the Royal Readings in Moscow. Rogozin said that such an opportunity may appear when the developers have at their disposal oxygen-hydrogen engines, which will have a sufficient supply of energy, and to put a payload into orbit, and so that it is possible to return the first stage to Earth. Work on the creation of the return stage is carried out by kb "Salyut". "Of course, we need to look at the economics of this whole business, because unlike the Americans, we do not have the opportunity to land on offshore platforms due to our geography. We will talk about landing the first stage on a specialized platform somewhere on the shores of the Sea of Okhotsk," Rogozin added. "Angara" is a family of environmentally friendly launch vehicles of various classes. It includes light carriers "Angara-1.2", heavy - "Angara-A5" and modernized "Angara-A5M", increased carrying capacity - "Angara-A5V". The first stage of heavy rockets consists of five Universal Rocket Modules assembled together. The first fire test of the boosted oxygen-hydrogen engine of the new upper stage for the Angara-A5 rocket was held at the end of 2021 in the test complex of the Voronezh Rocket Engine Building Center.
As expected.

Yup, get Angara flying to replace Proton and establish a fully nationally-controlled heavy-lift capability for national security purposes, then look to see if reusability is worthwhile.
First steps first however - get Angara serial production underway and flying real payloads. The first part is technically achieved, now they need to put pedal to the metal and start turning out launchers and flying missions.
The first launch of the Angara from Vostochny will take place in December 2023

MOSCOW, 11 April. /TASS/. The first launch of the Angara from the Vostochny Cosmodrome will take place in December 2023, the Angara-1.2 light launch vehicle will be launched. This was announced by the Director General of Roscosmos Dmitry Rogozin.
"The first launch of the Angara will take place as scheduled - December 2023. First, the new launch complex of the Vostochny cosmodrome will test the Angara-1.2, then the heavy one," Rogozin wrote in his Telegram channel . According to the head of Roscosmos, at the same time, in the fourth quarter of 2023, tests of the emergency rescue system of the Orel spacecraft will begin.
The launch of the Angara-A5 launch vehicle, which was originally scheduled for December 2023, has been postponed to April-June 2024. In an interview with Rossiyskaya Gazeta , Rogozin said that in the summer of 2023, two rockets would be delivered to the Vostochny Cosmodrome: Angara-A5 and Angara-NZh (a test model for "fitting" the launch complex). First, the Angara-NZh will be refueled, then a ship will be installed on it and tested with a simulation of an accident at the start.
"The ship must be torn off by solid-propellant engines from the rocket, retreat to a safe distance, release a parachute and land at a designated point. The second type of test is an imitation of an accident in flight at an altitude of 10-12 km - Qmax. We will do this during the first launch from Vostochny "Angara-A5". I think that this will happen in April-June 2024," Rogozin said.
The state corporation, the head of Roscosmos stressed, must make sure that everything is working properly.

the bigger A-5 main customer is the military to get big satellites up into GEO orbits isn't it I'm not entirely sure ... but .... GEO satellites use equatorial orbits - so Vostochny probably is better ?
and yeah that idea of not "scattering" the 4x first stage boosters .... is pretty pragmatic use the central booster to land the thing - and you then have a nice ready-made wide landing base - who needs popout landing legs then ?
inspired by the Proton rocket base ? its like recreating the bottom bit of the Proton isn't it it looks like it has detachable side boosters .... but they aren't
I'm pretty sure that's where the "eureka" moment came from .... after a few vodkas
The modernised A-5M with the hydrogen upper stage (A-5V) will have a lifting capability to LEO of some 37.5T, or a little under 2x the capability of Proton. Operating both A-5M and A-5V will provide Russia with powerful workhorses of a scale that are ideally suited to orbital assembly of complex structures. Orbital stations, lunar complexes, Zeus nuclear-electric deep-space craft

yep the "map" says you need a big rocket to get things in LEO or GEO or the Moon or further so yeah I knew all that .... thanks to this cool map
think I read somewhere to get to the Moon from Earth orbit you need approx twice as much fuel as payload to get away from Earth's gravity still a hefty chunk of fuel .... (in a chemical rocket) after you have already used 85% of your initial Earth launch weight to get off Earth in the first place .... coming back is a doddle .... slowing down again is the tricky bit
anyway here's the "Subway map" I can't seem to attach images ... maybe I'm using the wrong browser ? ... or I need to drink less ... or both here is a copy of it ....
interesting bit is .... when does a nuke or solar powered ion drive make more sense ? Mars and deep space for sure ..... but the Moon ? ..... probably not for humans ? definitely for cargo runs
I think Elon Musk is a complete lunatic re Mars .... same re the Moon - why bother with a super heavy rocket ?
I agree with Big Gazza Angara A-5V is big enough surely it is more sensible to lob up modules into Earth orbit and connect them together there first
you need much simpler connections of comm and power between modules that don't need space walks - yes eg IR comms and probably induction power connections
surely solving that is a lot cheaper than building idiotically huge rockets
then you start to arrive at the obvious your spacestation modules and deep space craft will use the exact same modules once you get your nuke powered ion drive "tugs" working like shunters in a railway yard ....
probably just chemical based shunters in LEO like the one they trialled recently delivering the Pritchal module to the ISS that was definitely a "shunter/tug" trial ....

Modular LEO assembly makes a lot of sense. With nuclear propulsion the amount of mass in terms of fuel needed to deliver to orbit is vastly reduced. But LEO is already enough initial kinetic energy to require much less energy to reach the Moon than straight from the surface (about three times less).
The Yanisei SHLV is an URM so it should not be super expensive compared to the Angara. It will have Zenit replacement modules which should have enough production volume to give them economies of scale. I have not seen any economic analysis comparing the Yanisei to Angara for Moon missions. The Angara will be more than enough for space station module delivery.

so Rogozin is saying here ..... we won't waste our time with methane rockets right now ... or superheavies Angara family is fine - as is the trusty Soyuz
main focus is now on .... Earth satellite network with ROSS being the central garage thereof ?
this certainly caught my eye re their recent experiment with a space shunter/tug delivering the Prichal module to the ISS
"decide whether to continue cooperation on the ISS or move to ROSS. And then we'll decide what we'll do with our two new ISS modules, which we docked last year."
ie will they unhook them and shunt them to the new ROSS spacestation ?
if they start shunting modules around .... Angara A-5 is perfect for any future plans
The Omsk production association "PO Polyot" in a year will be able to produce eight heavy launchers "Angara-A5" and two light "Angara-1.2" per year.
This was announced by Roscosmos CEO Dmitry Rogozin.
"At the moment, we have the possibility to produce at least four heavy and at least two light Angara missiles at our Siberian site in Omsk. And in a year, we will produce eight heavy and two light Angara missiles, which will completely cover all the needs of any customer, be it Roscosmos or the Ministry of Defense," he said on rossiya-24 TV channel.
4x Angara A-5s at present and up to 8x by next year that's a lot of big rockets ..... seems a satellite construction breakthrough is expected ....
MOSCOW, April 29. /tass/. The Angara-1.2 light rocket launched for the first time with a spacecraft in the interests of the Russian Defense Ministry on Friday from the Plesetsk cosmodrome in the Arkhangelsk region, the ministry told reporters.
"On April 29, at 22:56 Moscow Time, a successful launch of the Angara-1.2 light-class rocket vehicle was carried out from the launcher <...> of the Plesetsk State Test Cosmodrome by the combat crew of the Aerospace Forces of the Aerospace Forces with a spacecraft in the interests of the Russian Defense Ministry," the ministry said.
They clarified that all pre-launch operations and the launch of the rocket were carried out in normal mode. The launch and flight of the rocket is controlled by a ground-based automated control system.
The Ministry of Defense clarified that at 22:58 Moscow time, Angara-1.2 was accepted for ground support by the Main Test Space Center named after G.S. Titov of the Space Forces of the Aerospace Forces.

I noticed in the video I posted earlier that the rocket is already "off-centre" as it passes the top of the tower - around 10 seconds or a bit less ? is it the small fins already starting the "roll" sequence ?
you can see those fins on the video you just posted inside the hangar there
Anatoly Zak calls them "roll control surfaces"
http://russianspaceweb.com/angara_urm1.html
The engine's suspension system enables to rotate it up to eight degrees in order to steer the rocket along the pitch and yaw axis. The roll of the vehicle can be controlled with two aerodynamic stabilizers and four thrusters, also installed in the tail of the rocket and propelled by the hot gas generated in the main engine.
The "off center" is because it is following its non-vertical flight trajectory. I recall one troll on this board going on and on about how the first Angara launch a few years ago was swaying when it is obvious that it is the cameras that are doing all the moving.
There is some sort of fixation in the west on the "low accuracy" of Soviet and Russian rockets and missiles. Clearly an insecurity complex. I am not attacking your post, but Zak is a pro-western stooge that routinely panders to western bigotry.

seems that way ?
The Angara rockets implement a withdrawal from the launch table - therefore, the rocket immediately starts with a slight inclination, which almost immediately takes the rocket out of the zone dangerous for the launch complex. So even if the rocket's engines fail a few seconds after launch, or an explosion occurs, the launch complex will receive significantly less damage. This is a simple precaution. The history of the "N-1" disasters was remembered and learned this lesson. Let me just remind you that the Angara-A5 is almost 700 tons of rocket fuel and oxidizer. The explosion at the initial stage of the launch is equivalent to the explosion of a tactical nuclear charge.
