In the defense industry explained the essence of the problem with the nozzle "Bulava"

In the defense industry explained the essence of the problem with the nozzle "Bulava"The launch of the Bulava 6 of September 2013 of the year from the board of the first serial underwater missile carrier Alexander Nevsky of the 955 project (cipher Borey) was affected by a malfunction of the mechanism that pushes the nozzle out of the rocket body, a retractable rod, a source in the Russian defense industry said.


“This is the second case of an emergency start-up of the Bulava caused by such a malfunction. For the first time this happened 9 December 2009 of the year when shooting the Bulava from the board of the Dmitry Donskoy underwater cruiser, which was observed by the people of Norway. Then the stem broke because it was made not of titanium, as it should have been, but of steel. As a result, the nozzle did not come out of the rocket, an accident occurred, ”the ITAR-TASS source specified.

“6 of September of the current year, that is, almost four years after that accident, a relapse of the disease occurred when the retractable nozzle rod again didn’t work properly,” he said. The source did not specify the reason for the stock failure this time.

He explained that before the release of the rocket from the mine, the nozzle is inside the case to reduce the size of the rocket. It extends from the rocket body when it leaves the water at the same time as the main engine is turned on.

In September, Defense Minister Sergei Shoigu decided to suspend the state tests of the Alexander Nevsky and Vladimir Monomakh submarines and conduct five additional launches of the Bulava intercontinental ballistic missiles due to an unsuccessful launch of this type of missile.

To clarify the causes of the incident, a commission was created under the leadership of the Navy Commander-in-Chief, Admiral Viktor Chirkov, who began a large-scale verification of the missile enterprises.

On November 14, a source in the military-industrial complex announced that the launches of ICBMs from Alexander Nevsky and Vladimir Monomakh submarine-launched missile carriers would resume only in the summer of 2014.

November 20 experts who investigated the unsuccessful launch of a ballistic missile, called the cause of the accident violation of technology in the production of the rocket. According to Deputy Defense Minister Yuri Borisov, the reasons "are technological in the manufacture of the rocket and are associated with a nozzle." At the same time, there is no doubt about the “correctness of the manufacture of the product itself as a whole”.

    Yes, this is a hangover! But with Bulava it turns out very interesting: the technology is violated and who is punished, and now it will be the same? Something resembles an elementary sabotage: the missile itself is discredited and the capabilities of the defense industry are questioned! Someone really does not want the serial production of the "Bulava" to begin!

    A counterfact or something was put on a rocket, how could a titanium part be replaced with a steel one? Now they will urgently find a hard worker and dump everything on him. Vasya drank the part, and then, frightened, he turned it on a lathe and replaced it.

      Then it turns out that they made of titanium, but they also mixed aluminum with titanium, so that not one but two nozzles are made, but where are the technologists, and who will personally answer for the hack work ???

    From the article: - "... then the breakage of the stock occurred due to the fact that it was not made of titanium, as it should be, but of steel ...".

    What, all the titanium goes to the chassis for the Boeing? Apparently there is more profit ?!

    As soon as the cause of the next zugunderder with missiles-planes-with any high-tech iron, red border and thick print is called from the very top, you must write-

    THANKS FOR THE "EDUCATION REFORM!"

    There is not much time left and such a dance will begin that it will not seem a little, there are fewer and fewer specialists every year. Even the Supreme Commander somehow mentioned the need to train young personnel! And where to get the "blank" to make a "young frame"? Tell me from school, is it after the exam, is it after the innovations in the educational process?
    There are some under-educated ones. Menagers and vile dazers are no higher. Students must be torn off again and sewn to their shoulders so that they could even hammer a nail and not make a rocket.

      What does education have to do with it? even a monkey will understand: if it is said to be made of titanium, it is necessary of titanium, then there is no need to be a specialist. This is called simply betrayal!

      PS: everyone offends the exam, before you say so, take a couple of hours, go through it and share the results. The old system is dead. At institutes, examinations are taken much less qualitatively than the exam. The introduction of an analogous exam for regional universities will be a real purge from pseudo-education.

      I don’t know about the French frogs, but remember the sabotage with Proton, when a worker shoved a sensor upside down and then choked in the USA, as a result, Proton crashed on the air. Why couldn't they do the same with the Mace?

    Today, the son lost the wheel on the car, the bolts were unscrewed. I changed the wheel, did not stretch them again, after I drove five kilometers. It is necessary to ALWAYS do this, even if the nuts do not stretch when lifting))) But you will be sure that nobody will call you Loch on the road)))

    It seems to me that if the reasons for the unsuccessful launches were of a technological nature and were associated with the nozzle extension mechanism, then all this would have been clarified even before the launches from submarines. The KB has accumulated vast experience in solving such a problem. Speaking of the human factor, one must understand that not everyone is allowed to manufacture critical elements of the propulsion system, and military acceptance carries out triple control. Not so simple, gentlemen.

    Fine! Someone decided to replace titanium with steel. Previously, for such savings, many would have gone to clean the snow or fell down the forest, but now they will threaten with a finger or they will find the last uncle.

    Well, replacing the material ... is a delicate matter. It surprises ... it was replaced with a heavier one, the fact itself ... when manufacturing did not take into account the coefficient of thermal expansion, the rod simply jammed or did not take into account a couple of materials that worked, the quality of the surfaces and now it stuck to you .. It was necessary to introduce additional coverage to slide ... with saving. In general, the matter of replacing is not a simple one, it requires a lot of approvals, including by the trader / developer ... if they did and released it means they agreed on the card ... then the designer who coordinated it was screwed up ... and if there are all idiots? That Mace flies against the laws of physics.

    stock failure occurred due to the fact that it was made not of titanium, as it should have been, but of steel.

    Well this is complete ... (5 warnings) !!! I, as a specialist in the field of NK, simply DO NOT UNDERSTAND !!! AS??????? Yes, the soul must first shake out with the beginning. Lab of spectral analysis, military representatives and the beginning. workshops where this rod was made, and then the time to solder! After all, at one time everyone signed the responsibility, right up to the criminal where necessary ... And hard workers ... They don’t understand what metal they process, or what ?????? Steel is not distinguished from titanium ??? Yes, at our factory, the first one to report a material mismatch was conditional Uncle Vasya-turner, milling machine operator or drill driver !! If the OTC and the LNC have been spoiled, then Uncle Vasya will correct! Madhouse!

    The article is complete nonsense. Nothing comes out there at the start, for the Bulava flight control in the first stage operation area is carried out by a central rotary partially recessed nozzle based on an elastic joint.. The second and third stages are equipped with a central rotary partially recessed nozzle with folding nozzle nozzle (deflector)This is extendable nozzle portion a rocket engine designed to increase its efficiency in rarefied atmospheric layers or in a vacuum. It is precisely this mechanism that has failed. The nozzle nozzle (deflector) serves to control the thrust of the turbojet engine. It should be extended when the air pressure nozzle with nozzle will become equal to the gas pressure at its cut. And already at the end of the OUT, solid propellant motor "cutoff" is applied - charge extinguishing by rapidly decreasing the pressure in the engine chamber, deflecting the jet stream with the help of the rotary nozzles themselves plus auxiliary engines. For which they came up with this most partially recessed nozzle on an elastic hinge. Therefore, Topol-M (and Bulava) do not have lattice stabilizers and rudders that its predecessor, Topol, had.

    The case was helped to design the elastic nozzle: this idea lit up after the inventor saw a folding cup (they were popular at the time). I am a relative of this innovator. Not so modest)

      In the 80s, the Yuzhnoye design bureau developed the technology of expanding the nozzle nozzles (cup sections) in the "hot" mode by the products of the stage motors. In order for the glass to open, experienced people did not push (pull) but sharply shake it and it would open effectively with a bang. I do not know what method on Bulava, but the probability of this particular method is quite high for MIT missiles, since almost all the developments of the Yuzhnoye design bureau went to MIT.
      Voobshem concluded that all of our inventions go through a glass drinksIs the innovator from Dnepropetrovsk by any chance? Or from the "invalid home" on Berezovaya Alley?

    Everything we had at the factory. But, what would SO stupidly ruin the product ... Never, yes! I do not know NTD in the field of control in space. prom ... We had the so-called sample witness (well, or somehow called differently ...). Those. a piece of material from which this or that detail was made. ALWAYS after presenting a batch of VP products, this piece has undergone comprehensive testing. Meaning: if they screwed up in it, then it means: they screwed up in products. But there has never been anything like that ...

      Yes, it’s probably not about the details and not about the alloys. As the new MIT rockets went, this mess with the nozzle periodically pops up. Topol-M, the fifth or fourth test launch was exactly the same crap, only then they said that they were testing a self-detonation system and everything is fine. Apparently Solomonov decided to use Utkin's idea from Molodets and ARK Krechet, both in order to reduce the missile OUT time when separating the stages, it provided for a "hot" expansion of the nozzle nozzle into the operating position by an outflowing stream of combustion products and the possibility of deflection and maneuvering in pitch and yaw when starting along a flat trajectory.
      But that's why, on average, out of 10, one has this malfunction. There’s food for thought and scratching turnips.
