Rocket heart

Since such a binge has gone, I want to tell a little and show about the rocket engines

Many of us in childhood probably dreamed of becoming astronauts. Or at least to some extent be involved in astronautics.

Even though I am an engineer by training, I was always amazed and fascinated by engines.

1. RD-861K in glass. Developed on the basis of the RD-861 engine used on early modifications of the Cyclone launch vehicle. Since 2007, conducted fire tests. It is planned to use this engine in the third stage of the Cyclone-4.

2. Also OKB-586 (now Yuzhnoye Design Bureau) was engaged in the development of the lunar module.
Engine block "E" of the Soviet lunar program. Of which there are only three copies: two here, another one in the MAI.

3. The engine is unique for its traction characteristics, service life, as well as the possibility of multiple starts in a vacuum.

4. The lunar ship was a structure made of an astronaut airtight cabin, a compartment with orientation engines and a docking unit, an instrument compartment, a lunar landing gear, and an "E" rocket unit.

5. Boris Ivanovich Gubanov was appointed to lead the Yangel Design Bureau for the development of the E block. The development of the propulsion system engaged KB-4, headed by Ivan Ivanovich Ivanov. The development of the engine began in the Moscow region at the stand of the Khimmash Research Institute, where a team of OKB specialists traveled every month. Then the tests were continued on the bench put into operation in Dnepropetrovsk. The engine has not been able to achieve full failure - during the life test, the engine worked flawlessly for 10,000 s with the required 470 s.

6. Block "E" was supposed to provide braking of the lunar ship, maneuver and landing on the surface of the moon. The time spent on the surface of the moon from 6 to 24 hours. After that, the ship took off from the surface, and the orbital ship was already dispersed using the “I” block (developed by the OKB-2, under the guidance of Isayev AM)

7. One of the two turbopumps of the engine block "E".

8. Turbopump of the UR-100N (15A15) missile. He already came across earlier .

9. The engine of the lunar block "E". Whole.

10. The RD-250 engine, which is installed in the first stage of the R akety- N cyclone “Cyclone” (three pairs are installed). They stood in the first step of the P-36 (8K67). More information about the development of this engine can be read here .

eleven.

12. 15D12 (RD-857) was developed in KB-4 OKB-586 (now Yuzhnoye Design Bureau) under the leadership of Ivanov I. in 1967 for the second stage of the RT-20 mobile complex. The complex, alas, did not go into series, but its base was developed by the RD-862 engine, which was installed on the second stage of an ICBM (intercontinental ballistic missile) 15A15 (UR-100N).

13. Huge LRE, unfortunately its labeling is unknown. There is an assumption that this is RD-224D from the second stage of the 8K66 rocket, which did not go into the series.
