Roskosmos refused to sell the engine RD-180 in the United States. Cause - Response Santa. Where the engine will use and what the US will answer, let's tell later.

RD-180 is a liquid rocket engine with a double combustion chamber. Designed based on Soviet engines RD-170 and RD-171. Americans used the engine for the first stage of heavy pH "Atlas 5". Planned to buy up to 2023-2024.

Now RD-180 will serve for the designed pH "Soyuz-6", also at the first stage.

In response, the United States threatens to disconnect Russia from GPS. But Dmitry Rogozin does not survive, as there are GLONASS in Russia. In addition, the head of Roskosmos reported that it would be difficult to technically implement a disconnection from GPS.

In Russia, the Sfera IT project starts soon. This is a domestic app for communication, job search and an interesting pastime. To learn more, click on the link. The project is open to invest. Thanks for the support!

Since 2019, Roskosmos is developing Soyuz-6 on the basis of the "Soyuz-5" pH. Tests are scheduled for 2025, on the "Eastern" cosmodrome.

"Soyuz-6" - pH of the middle class, is able to raise 9 tons of payload for near-earth orbit. Replace the outdated "Soyuz-2". Also "Soyuz-6" is a prototype 2 of the super-income "Yenisei". "Yenisei" is the main pH for the 2 phase of the Russian Moon Program.

As mentioned above, Soyuz-6 will work on the RD-180 engine, which in the Russian cosmonautics did not use. The manufacturer of the engine NGO Energomash adapts the RD-180 for a new rocket. The engine will be equipped with increased protection against fire, a new control system, a system of emergency protection that will be triggered earlier in troubleshooting.

"Soyuz-5" - a frequency band-carrier with 2 launch stages. At the first stage of the rocket, the liquid oxygen-kerosene engine of the closed cycle - RD-171MV is equipped. On the second - RD-0124MS.

RD-171MV is considered the most powerful liquid engine in the world. The thrust is 740 tons. This is 4 times more than the American Raptor engines are issued, an average of 204 tons.

The rocket will raise 17 tons of payload for near-earth orbit. For the manufacture of tanks, the new aluminum alloy P-1580 is used. Due to the alloy increases the mass of the output payload.

During the construction of "Union-5" introduce new technologies. For example, friction welding with stirring. This technology improves the quality of the seam. The fact is that when melting aluminum loses properties. With friction, aluminum is not melted, but heats up to 200. At such a temperature, the metal is deformed and forms a welded connection.

Technology is common in the world, but is first used for the manufacture of large-scale products. The diameter of the fuel tank is 4.1 m, and the length is 50 m.

Another technological feature of the "Union-5" is a deserted start. It is assumed that Soyuz-5 will replace all pH of the middle and heavy class - Soyuz-2, Zenit, Angora, Proton-M.

Energomash has already experienced difficulties due to US sanctions. In 2014, the US government banned United Launch Alliance of the Transaction with Energomash and the use of RD-180. But in May of the same year, the ban was removed. This time Russia has refused to cooperate with America on its own initiative.

Maxim Ovchinnikov, Maxim Ovchinnikov, departments of Roskosmos, noted that the termination of the supply of RD-180 will become a serious loss for Energomasha. The company will lose revenue of 10-13 billion rubles. But Roskosmos works on expanding the list of customers in order to continue not to depend on 2-3 clients in this market.

Despite the losses, Roskosmos is planning 20 launches in 2022. Before the failure of the OneWeb launch and freezing of the Kuru cosmodrome, 32 launches were scheduled. It would become a record indicator for Russia.

Dmitry Rogozin said that the United States wants to turn off Russia from GPS:

2008 is considered the start of mass use of GLONASS for civilian purposes.

Boris Katorgin, Academician of the Russian Academy of Sciences and the creator of the RD-180 engine, believes that from the point of view of the economy, the sale of the RD-180 is unprofitable for Russia. RF sold 120 engines and earned $ 3 billion on its forecasts, the United States will not be able to quickly create an alternative to RD-180. Now, except for Russia, there is no one to use the engine, since it requires an appropriate superheavy pH, which means that the creation of a whole industry.

What do you think there will be an effective adaptation of the RD-180 for the missiles available in Russia?
