The most powerful liquid-propellant rocket engine in the world has been tested in Russia


On December 19, 2020, NPO Energomash (part of Roscosmos) conducted the first full-size fire test of the world's most powerful liquid-propellant rocket engine, the RD-171MV. The head of the state corporation Dmitry Rogozin wrote about this in his Twitter account.


All parameters are normal

- Rogozin said.

He noted that this power unit will be used at the first stage of the newest medium-class launch vehicle Soyuz-5. At the same time, the CEO promised, responding to subscribers' requests, that next time a video of such an event would be made and published.

We remind you that the development of "Soyuz-5" started in 2016. It should replace the Zenith LV, manufactured in Ukraine. Wherein RD-171MV - an improved engine from the first stage of the Zenit launch vehicle. The second stage of Soyuz-5 will be equipped with the RD-0124MS engine - a modernized power unit from the third stage of the Soyuz-2.1b launch vehicle. This rocket engine will replace the Ukrainian liquid-propellant RD-120 (Yuzhmash).

In 2023-2025, it is planned to conduct at least three test launches of Soyuz-5 at the Baikonur cosmodrome. After the completion of the tests and until 2036, at least two Soyuz-5 launches are planned annually.

In 2018, the starting one was transferred to the ownership of Kazakhstan at Baikonur, technical and assembly and testing complexes for the Zenit LV. Within the framework of the agreement on the joint Russian-Kazakh project "Baiterek", this infrastructure should be adapted for the launch vehicle "Soyuz-5" at the expense of Astana.

      I wonder which of the regulars of "Reporter" is so burnt by the fact that I called this undoubtedly good engine a "noble unit"?

    As usual - 15 year plans. Mediocrity! All work is aimed at theft!
    1945-1961, from scratch to human space flight. Here's how to work! And we have a feeling that they are working as a favor. It seems that there should be potential and trained personnel, but there is no desire to be leaders and pride of the country. The result is such as begging for money. Musk has a whole space program, right up to the exploration of Mars. China is also not lagging behind. And we, as if stuffing ourselves into partners: "This is what we can do, we can do it." Two launches a year? It is not surprising that we do not even have our own meteorological satellites, and Glonas cannot be launched completely.

    We do not have a satellite component, the Russian constellation simply died ... Therefore, we are now looking for an opportunity to follow the experience of the same Japanese who began to use small satellites launched for six months or a year into low orbits ... This year we will try, if we agree , make one test run, ”Yakovenko said.

    Putin surrounded himself with mediocrities and flaunts how "white and fluffy" he is.

      "This is what we can do, this is what we do." Two launches a year? It is not surprising that we do not even have our own meteorological satellites, and Glonas cannot be launched completely.

      Are you splashing saliva again and causing panic? Yes, there was a nuisance ... What now to tear the hair on the back of the neck? Maybe just calmly wait for the launch of the next ones?

      The Russian meteorological satellite Meteor-M has lost its orientation due to external influences, according to a statement from Roskosmos. According to preliminary data, a micrometeorite got into the device.

      What does not suit you according to GLONASS is not clear at all request As of 19.10.2020:

      A total of 28 KA in the GLONASS OG
      Used for their intended purpose 23 KA
      At the stage of entering the system -
      2 spacecraft temporarily withdrawn for maintenance
      On the research of the Chief Designer -
      Orbital reserve 1 KA
      At the stage of flight tests 2 KA

      Are you proposing yourself for a position? laughing

      By the way, the link to information with lamentations of Yakovenko is not working request

      Shhh, quieter, why so "fire up" effective management? People make money. Money, firstly, loves silence, and secondly, it goes to money, and all this is in silence.

    Again they will sell to the Yankees as 180. Although now we are launching the British satellites themselves.
