    Russia may use RD-180 engine for super-heavy carrier rocket

    http://tass.com/science/1030099

    ZHUHAI /China/, November 9. /TASS/. The RD-180 engine may be mounted on Russia’s super-heavy carrier rocket and modernized Soyuz-2 launchers, Energomash CEO Igor Arbuzov told TASS at the Airshow China exhibition on Friday.

    "As part of the work to develop a concept of the super-heavy carrier rocket, the option of using the RD-180 engine on the second stage of the carrier rocket is being considered," the chief executive said.

    "Also, in view of its reliability and indisputable leadership in its class, the possibility of using it on newly-created and modernized domestic launchers is being considered. In particular, its use for modernizing Soyuz-2 rockets may be considered," he added.

    As Energomash Chief Designer Pyotr Lavochkin explained, "This is consonant with the concept, which suggests that all the parts of the super-heavy rocket should be flight elements featuring their serial production and the statistics of launches."

    RD-180 engines are used on the first stages of US Atlas space launch vehicles and have never been mounted on domestic rockets. An engine variant was planned for its use in the project of the Russian Rus-M carrier but the program was halted.

    Contracts signed by Energomash for the delivery of RD-180 engines to the United States are valid through 2020 when six such engines are scheduled to be transferred to the US side. Energomash may also exercise an option on the delivery of RD-180 engines to the United States in 2021.

    In 2014, the US Congress imposed a ban on the use of RD-180 engines amid a deterioration of relations with Russia but lifted it in 2015 when it became clear that the United States would be unable to manufacture rocket engines on its own in the next few years. However, as NASA Chief Jim Bridenstine said in August, the United States will continue developing alternatives to RD-180 engines.
    Super-heavy carrier rocket

    Head of Russia’s State Space Corporation Roscosmos Dmitry Rogozin earlier said that all of Roscosmos’s design bureaus would participate in developing a super-heavy carrier rocket.

    According to Rogozin, Energia Space Rocket Corporation has already examined proposals on the rocket’s technical design and a plan of organizational measures.

    In accordance with the designers’ plans, the Russian super-heavy carrier rocket should be able to deliver more than 70 tonnes of cargo into low near-Earth orbit at the first stage. Its basic task is to provide for a possibility of flights into deep space, in particular, to the Moon, Mars and other planets. The construction of infrastructure for this rocket is due to begin at the Vostochny Cosmodrome in the Russian Far East in 2026 and its first launch is scheduled to take place in 2028.

    The concept of creating a super-heavy carrier rocket envisages maximally utilizing the accumulated technological potential. The super-heavy carrier rocket will also incorporate the elements and technologies of the medium-class Soyuz-5 launch vehicle, which Russia is developing. In Roscosmos’s estimates, the work to create a super-heavy carrier rocket and build the required infrastructure for it will cost 1.5 trillion rubles ($22.7 billion).

    As was reported earlier, Roscosmos has started preparations for drafting a federal target program for creating a super-heavy carrier rocket.

    I could understand if it was a draft design (eg no detailed fabrication drawings or avionics/controls schematics developed) , so maybe the issue is just simply poor reporting or translation?


    there were some reorganizations on its way (in Roscosmos) some people quit to S7 and I' presume money flow is not so constant. Just my guess.

    It's supposed to be used on seconds stage, no need for new model. It's proven to be reliable as hell and production is in full swing. It's dirt cheap as well at this point.

    First stage should get new engine but it will be based on Energia same as RD-180. They could use 180 for first stage as well without too much payload compromise if they want to.

    In "Roskosmos" they estimated the cost of launching a Soyuz-5 rocket


    MOSCOW, November 11 - RIA News. The cost of launching a new Russian Soyuz-5 rocket will amount to $ 60 million, according to a video posted on Twitter by the head of the
    The launches will be carried out with the help of the Baiterek missile system, a joint project of Russia and Kazakhstan.

    As emphasized, the operation of the complex will allow enterprises of the two countries to "annually master 360 million dollars with six starts per year."

    This clarifies that the "Soyuz-5" will be able to compete with Falcon 9 Ilona Mask and European Ariane 6.
    +++
    In April, the ex-general director of Roskosmos, Igor Komarov, said that the new medium-class rocket Soyuz-5 should cost no more than 30-35 million dollars. Prior to this, Sergei Sopov, CEO of S7 Space Transport Systems, criticized the rocket developed by RSC Energia for outdated features and high cost.

    After that, as Riav ​​Akhmetov, acting general director of the Progress Rocket and Space Center, told RIA Novosti, Roskosmos ordered to reduce the cost of the Union-5. At the same time, the general director of RSC Energia, Vladimir Solntsev, announced that a cheaper version of this rocket will be created for the S7.

    Rogozin proposed to test the cosmonaut rescue system on the developers

    MOSCOW, November 11 - RIA News. The head of the Roscosmos state corporation, Dmitry Rogozin, suggested including in the crew of the new Federation ship the developers of the new emergency rescue system, a source in the rocket and space industry told RIA Novosti.

    "When Comrade Stalin was shown an armored vehicle in which he should drive, and that the PCA did not break through, he put the designer of this car inside and riddled it with a machine gun. The designer remained alive because the car turned out to be good. I suggest writing Designers must be put in the ship during SAS tests (emergency rescue systems - Ed.) "- quoted the source of Rogozin's quotation, which was made at a meeting in the Rocket and Space Corporation Energia on Saturday.

    According to the interlocutor, Rogozin reacted to the proposal of one of the designers to install a new emergency rescue system on the Federation ship and to reduce the number of its tests on the new ship.

    Launch of Soyuz-2.1a carrier rocket from Vostochny space center scheduled for December 25

    According to a space industry source, it is scheduled for 05:07 Moscow time

    MOSCOW, November 9. /TASS/. A Soyuz-2.1a carrier rocket is scheduled to be launched from the Vostochny space center in Russia’s Far East in the small hours on December 25, a source in the space industry told TASS on Friday.

    "The launch of a Soyuz-2.1a carrier rocket with a Fregat booster is scheduled for 05:07 Moscow time on December 25. It is planned to put in orbit two Russian Kanopus-V No5 and Kanopus-V No6 land remote sensing satellites and about 30 smaller spacecraft, mostly of the CubeSat class," the source said.

    The Fregat booster has already been dispatched to Vostochny. Preparations for the launch are planned to begin at the end of the week. The Kanopus-V satellites are being checked before being taken to the space center. The Soyuz-2.1a launch vehicle has been at the cosmodrome since June 18, 2018.

    It will be the fourth launch from the Vostochny space center, with the previous one taking place on February 1, 2018, when two Kanopus-V satellites were put in orbit.

    Kanopus-V satellites are designed to monitor man-induced and natural disasters, including weather emergencies, large discharges of pollutants into the atmosphere, and also to monitor agricultural activity, natural (including water and coastal) resources and land management.

    The satellites weighing 465 kg are launched into sun-synchronous orbit about 510 km high. The satellites can operate for five years.

    The first Kanopus-V satellite was launched from the Baikonur space center in Kazakhstan on July 22, 2012.

    Vostochy is Russia’s first civil spaceport. The first successful space launch was performed from Vostochny in April 2016 when three satellites were put in orbit. Vostochny was built to ensure Russia’s overall access to outer space and reduce its dependence on Kazakhstan’s Baikonur space center.

    Roscosmos chief thanks participants in successful launch of Soyuz-FG carrier rocket

    The Soyuz-FG carrier rocket with the Progress MS-10 cargo spaceship blasted off from the Baikonur space center in Kazakhstan at 21:14 Moscow time on Friday

    MOSCOW, November 16. /TASS/. Director General of Russia’s space corporation Roscosmos Dmitry Rogozin has thanked all those behind the successful launch of a Soyuz-FG carrier rocket on Friday.

    "The state commission held a meeting after the launch of the cargo spaceship from the Baikonur space center. Dmitry Rogozin thanked operational crews for the successful launch," Roscosmos said on its Twitter account.

    The Soyuz-FG carrier rocket with the Progress MS-10 cargo spaceship blasted off from the Baikonur space center in Kazakhstan at 21:14 Moscow time on Friday. The Progress is to dock to the Zvezda service module of the International Space Station (ISS) at 22:29 Moscow time on November 18. The spaceship will deliver about 2.5 tonnes of cargoes, including fuels, water and pressurized gases, to the ISS.

    The Progress spacecraft was originally scheduled to be launched to the ISS on October 30 but the launch was rescheduled for November 16 following the abortive launch of October 11.

    Soyuz-FG carrier rocket with a manned Soyuz MS-10 spacecraft blasted off from Kazakhstan’s Baikonur Cosmodrome to the International Space Station (ISS) on October 11. On board the spacecraft were Russian cosmonaut Alexei Ovchinin (the commander of the Soyuz MS-10) and NASA astronaut Nick Hague.

    Following a smooth liftoff, the Soyuz’s booster malfunctioned between the first and second stages of separating, whereupon the crew was forced to abort the flight and switch to ballistic descent. The manned Soyuz MS-10 spacecraft ended up landing safely in the Kazakh steppe. The crew was not hurt. This was the first emergency situation with the launch of a manned spacecraft over the past 35 years.

    The incident-probing commission announced on November 1 that the emergency situation occurred after "a nozzle cover on the oxidizer tank failed to open due to the deformation of the separation contact sensor."

    The sensor was damaged during the assembly of the rocket’s first stage at the Baikonur Cosmodrome.

    No, it's a Progress replacement.

    It will be able to carry 3.5 tonnes of cargo (1.1 tonnes more than Progress) and will be launched with Soyuz 2.1v rocket (one without strap-on boosters and with cheaper simpler engine).

    No need to fire up Soyuz-5 and cargo Federation just to deliver 3.5 tonnes of stuff to low-earth orbit.


    Also I am pretty sure that cargo version of Federation will be identical to manned one just with interiors stripped of everything and completely stuffed with cargo.

    Finally, official render of nuclear space engine.  thumbsup

    Blue mist is droplet cooling system. Blue glowing circles are ion engines. Payload/capsule slot is in the back (right side of image).

    Whole thing should fit on one rocket and unfold in orbit.  

    Question   I can't tell if reactor core is in the front or back, can someone translate it?

    It is in front, translation is: production of electricity. How is cooling reactor, I do not understand, do you can explain?
    Ion engines are long time in experiments in former Soviet Union, some are tested in space, but problem for them is low power of output.

    How is cooling reactor, I do not understand, do you can explain?

    Awesome... droplets are a brilliant idea for radiating heat into space... using panels would not be very efficient but small droplets of material to absorb heat and then radiate it into space as it falls is rather interesting... though it would of course mean no sharp turns.... Smile

    Droplets have a better surface area for radiating heat into space.

    A panel would heat up and only slowly radiate heat into space but would not return cooled material to the reactor like droplets could... ie collect the cooled droplets and pump them back to the reactor to cool it.


    Obviously anyone who understand ION propulsion would know sharp accelerations are not what it is about...

    Ion engines are long time in experiments in former Soviet Union, some are tested in space, but problem for them is low power of output.

    Ion engines compared with rocket engines have a few advantages and a few disadvantages.

    Ion engines = low thrust, but also offer very very good fuel efficiency, and also very very high speed exhaust material, which means its top speed is much higher than for any chemical rocket.

    Very simply for a visit to a space station it makes sense to use a rocket for such a short trip, but for a trip to mars or any distant thing Ion engines suddenly become the best choice.

    Very simply on a trip to Mars you have two spaceships... one enormous one with rockets and one with a rocket and an Ion engine.

    The one with the rockets only fires those rockets and burns up three quarters of its fuel for its trip to mars in maybe 10-20 minutes of rocket burn which gets it up to speed and on its way and then shuts down the rocket and coasts all the way at a constant speed... as it approaches Mars it flips over so its rocket engine is pointing forward and fires its rocket again and burns up the last quarter of its fuel for its trip to mars to slow down so it can enter mars orbit... it only needs a quarter of its fuel because it has burned off the first three quarters to get to mars so it will be hundreds of tons lighter when it approaches mars than it was when it was in earth orbit so less fuel is needed to slow it down.

    This means if it had to fly to mars and fly back with fuel from earth it would need to be enormous because all the fuel to go there and come back would mean more fuel would be needed to move it because it was so heavy.

    In comparison an ION powered space ship might use a small rocket booster to get it moving on trajectory towards mars and then it would light up its Ion engine. the thrust of the engine would be tiny but would continuously be accelerating the spaceship. The first spaceship would blow past this second vessel in a blase of glory... but after a month of running the ion engine will have accelerated the space craft to very high speeds... actually rather higher speed than the rocket engine could ever get a space ship to... so the longer the trip the better the ion engine is... after less than a month or so the ion engined vessel would have passed the other vessel and would leave it behind.... after three and a half months the ion engined craft would flip over and start to decellerate... it doesn't speed up fast and it does not slow down fast... after 7 months the ion powered space craft would be manouvering to enter mars orbit... the rocket powered space craft would still be coasting 7 months into its year and a half journey to mars...

    ION engines are good... especially if you have a power source more reliable than sunlight... they only use tiny amounts of fuel and accelerate it to enormous speeds which eventually builds up and gets you there.

    Potentially the thrust of an ion engine will at least create a microgravity that will make life on the space craft more bearable.

    In orbit or in deep space there is no gravity so hot air does not rise and air does not circulate.

    If you stayed still you would suffocate because your body would consume all the oxygen in the air around you and your lung capacity would not be enough to make the air in your vicinity circulate and go through the carbon filters.

    This means in a space station or deep space space ship you need fans that constantly circulate the air and push all the air through carbon dioxide scrubbers to keep the air breathable.

    With a micro gravity from a small push from ion engines air will be easier to circulate normally... ie an up and a down.

    Thanks thumbsup


    As for cooling system, it will probably use lithium as coolant and is comprised of those 4 beams extending outwards marked as ''капельный холодильник излучатель'' in the picture (Cyrillic keyboard + goggle spellcheck comes in handy)  

    Coolant liquid (blue mist in picture) is sprayed into vacuum of space from those 4 beams where it quickly radiates heat and is then collected on those structures in the rear and pumped back into the system.

    Picture makes it look like there is a lot of liquid outside but in practice amount will be much smaller. Also, because liquid is sprayed into vacuum it travels in straight line so losses are minimal.

    There could also be electromagnetic system installed to additionally help prevent loss of liquid but it's not officially confirmed.  

    During maneuvers reactor would probably be throttled down to keep heat to a minimum because ship needs to move in straight line in order for cooling system to work properly. It should not be a problem because only one engine needs to operate during course corrections so they won't need more than 25% of reactor output.
