Fire tests of the new RD0124MS rocket engine began in Voronezh

February 12 2020

At the Voronezh Center for Rocket Engines, which is part of NPO Energomash, firing tests of the latest Russian RD0124MS rocket engine began. This was reported by the press service of Energomash.

According to the report, two successful fire tests of the first power plant with a shortened nozzle were carried out at the fire stand of the enterprise. Tests confirmed the stability of the combustion chambers under reduced pressure. A second power plant is also being prepared for testing. After testing both installations, specialists will proceed to testing the engine assembly.

As explained in the press service, the new RD0124MS rocket engine was created on the basis of the RD0124A engine with a thrust of 30 tons. The thrust of the new taxiway is twice as much as that of the base engine - 60 tons. The engine runs on naphthyl-liquid oxygen fuel components.

The RD0124MS engine consists of two units located on a common frame and thermal protection. Each of the blocks includes two diagonally located combustion chambers. The engine provides swinging of cameras in two planes, as well as operation when one of the blocks is turned off.

In the future, the new engine is planned to be used at the second stage of the promising Russian Soyuz-5 launch vehicle Irtysh, the first launches of which in unmanned mode are scheduled for 2022-2023.

"Irtysh" instead of "Angara 4," as far as I remember. If only the Irtysh is not turned into a project of an even larger and more powerful rocket, or it will even be destroyed, as is now customary among the MEENJARs ...

  Instead of Angara-A3.
  And this was the purest frankest recognition of the failure of the "modular" concept of the Angara.
  Without a wide range of launch vehicles (at least 1,3,5 URM at least) there is no sense in modularity - it’s only heavier and more expensive.
  It should be borne in mind that a wide line is a necessary, but not sufficient condition.
  even if there would be many different media on the workstation, it is not a fact that the modular concept was justified.
  
  It is not too late to abandon the Angara in its current form.
  You can even return to the original "eared" hangar - it was very competently and interestingly arranged.

    Modularity allows changing modules (URM1,2,3) gradually to more technically advanced ones. The current Angara is only the first stage launch vehicle. In principle, it was implied on the machines of later stages that the composite design of URM1, reusability and, the last trend before the dispersal of Khrunichev, a change in fuel pair. Last, IMHO, the trend of fashion and not expediency.
    But it is modularity that makes the design flexible and gradually and constantly updated.
    You can even change the manufacturers of URM to others who offer something more reasonable.

    Well, modularity implies the development of the structure in breadth - for A5, both A7 and A9 were viewed, at 48 and 56 tons. PN at the IEO. What does it give? This will allow to abandon the development of a separate superheavy carrier, which is very expensive and rarely needed. Test pH in parts.

      Today, modular missiles are being created - A1.2, A5, A5M (P). Subsequently, by the end of the current federal space program, A5B will be created - with a hydrogen stage, which in turn will be one of the stages of the Yenisei super-heavy carrier.

        In order to simply toss 20+ tons to the orbit of the moon, one superheavy rocket or four heavy rockets is required, in the latter case the cost of launching to the moon grows.

        The funny thing is that money was allocated to the Angara by the Moscow Region in 2006. And it did not distinguish them on A3.
        
        More precisely, the Ministry of Defense had a Zenit-2 at that time. And it was necessary to replace the Cyclone and Proton-M missiles. The first, because production ended, the second - at the insistence of Kazakhstan. That is why the "almost light" missile and the heavy one were tested in 2014. The need for the A3 arose in connection with the termination of the operation of the Zenit-M missile complex. But by this time it was decided to create the Soyuz-5 launch vehicle for the Zenit launch, without significantly altering it, as was the case with the A5 launch in Plesetsk.

  If only the Irtysh is not turned into a project of an even larger and more powerful rocket, or it will even be destroyed, as is now customary among the MEENJARs ...
  The Energia rocket and space corporation believes that the characteristics of the medium-class carrier Soyuz-5, also known as the Phoenix or the Irtysh, are not optimal. (...) Today, an option has been worked out with the possibility of putting 18 tons of cargo into the NOO (low Earth orbit): according to new findings, the carrying capacity can be increased to 20 tons. The mass of refueling is proposed to increase by 60 tons, and thrust - by 80 tf.

    If the second stage and the DM block on synthin translate more sense will be. And what they offer "Optimization" is not, but a stupid increase, and due to the extension of the development period. All Hangars and Zenits are already the last century, it is another matter if the project is updated due to new R&D.

    ... that the characteristics of the Soyuz-5 medium-class carrier ... are not optimal.
    
    Therefore, the approval of the draft design is constantly postponed. Either RD-191MS added a bit of traction, then RD-0124MS in the second stage gives new opportunities, then the proposed option with a methane second stage in the geometrical dimensions of the kerosene stage allows the same 23-24 tons to be brought to DOE and questions the existence of Angara-A5. Burning of the RD-191MS has already been completed, last week we successfully burned the nozzle for the RD-124MS, so the approval of the outline design of Soyuz-5 is just around the corner and this media can become unique.

  "Soyuz-5" or "Irtysh" is a middle-class missile, similar to the already closed Zenit-2SLBF launch vehicle
  
  Only thicker, larger and more powerful.
  
  It will be equipped with new upper stages of the class "DM-03" and "Fregat-SBU" (pictured)
  
  The former 45th Zenit site at Baikonur, recently returned to Kazakhstan and in a shortened version of the launch vehicle - Sea Launch, is assumed as launching complexes for this rocket, if S7 space, the current owner, has an opportunity to purchase it.
  
  Also, the first stage of this rocket is the first stage of the Yenisei super-heavy carrier.

    RD-0125A is not mentioned at all in the article.
    
    But in vain is not mentioned.
    That is why confusion and uncertainty arose.
    
    Here is what they write on the manufacturer’s website about RD-0125A:
    
    A single-chamber liquid rocket engine developed on the basis of the four-chamber RD0124A liquid propellant rocket engine, intended for use as a part of the Angara-A5 LV third stage unit.
    
    And here is how its intended use is described:
    Improving the characteristics of the launch vehicle is carried out by replacing one four-chamber RD0124A engine with a thrust of 30 tf
    "Spark"
    of two single-chamber engines RD0125A with a total thrust of 59 tf.
    This modernization leads to a significant reduction in the cost of the engine, as well as to an increase in the payload brought to orbits.
    
    Apparently, such a pair from RD-0125A was named the new RD0124MS engine.
    --
    And such an unobvious zigzag in the title is quite familiar in the space industry.
    Recall only all kinds of LVs called Unions with different numbers without any logic and continuity.

        Two RD-0124MS are not planned for use yet.
        
        Specified by the developer - you are right and wrong at the same time. As well as I am.
        
        Still, the name RD-0124MS is ONE engine. Of the two two-chamber on a common frame. At 60 tons of traction.

  In the message of KBHA there is not a word about the use of backlog on RD-125A. Is this a subject of discussion? In your photo is a model from the MAX exhibition. It was assumed that this engine will have a thrust of 60 tons, which means a nozzle of 60 tons and a turbopump assembly of 60 tons. In the KBHA infa, it is said about the maximum use of parts from RD-0124 (with a thrust of 30 tons) and about the possibility of disconnecting one block of two nozzles. And this means that two turbopump units from RD-0124 and a nozzle from the backlog of the RD-0124M engine, which just needs to have not four but two nozzles for a total thrust of 30 tons, will be used.

"Irtysh"? But what about "Angara"? Or has she already been "buried" as a "dead-end road"? Then, please tell me, who and how responded for the wasted money and time? And who will be responsible if "Irtysh" suddenly turns out to be a "failure" project ?! Aaaaaaaaa? !!!

In the USSR, 17 years after the Second World War, they flew into space, and here 30 years the rocket was built and the prospects for the effective managers seem vague

But what, to repeat the experience when they ripped off the whole country, but gathered a thread from all collective farms, villages and cities? Then it was necessary, the question was, live, undead. Repeat? But do not you conquer first of all? Standing in line for Chernukha? And getting to work on a cold, unheated tram? Tell me, they will find a new Beria, do not worry. And they will not be transferred to the right in terms of execution. Shoot, yes.

I haven’t read the chat yet, but I’ll say star-striped will come running to us again!
