NASA publishes photos of the Antares rocket explosion and final conclusions on the causes of the crash

47
NASA publishes images of the Antares rocket explosion that occurred about a year ago. All this time, the Americans tried to find out the cause of the accident, which did not allow the cargo ship Cygnus, which delivered food and scientific equipment to the ISS, to be put into orbit. As a result of a lengthy investigation, the Americans found that the AJ-26 rocket engine was “to blame”. This is one of the modifications of the engine still of Soviet production - NK-33, developed at the enterprise named after N.D. Kuznetsov in Kuibyshev (Samara).


NASA publishes photos of the Antares rocket explosion and final conclusions on the causes of the crash


in the report NASA it is reported that the cause of the explosion was a defect in the turbopump assembly, as well as the presence of a defect in the bearing of the same assembly. Another reason for the accident, American experts called the pollution of the turbopump unit "foreign particles".



While the experts continued to bring the investigation to the end, the liberal blogosphere has already begun to scribble posts that "the useless Russian industry is to blame." Some even said that the deployment of the "Russian" AJ-26 was malicious intent to harm the "exceptional nation of this world." The Ukrainian Svidomo audience has joined the spread of malicious publications. However, as it turned out, the Ukrainian Yuzhnoye Design Bureau was involved in modifying the US rocket engine. Ukrainian specialists carried out "modernization" of the fuel system and associated engine equipment, including the very turbopump units.

      What does the engine have to do with ??? !!! request

      NK-33 engines were shipped to the United States from a warehouse where they dusted for over 40 years. Age is age, even for iron. “When we tested the engines, we found signs of age-related fatigue, including cracks,” Culbertson said. “We conducted a thorough inspection of them and cooked them in some places.”

      In addition, according to the Guide, “each AJ-26 engine was equipped with a modern element base and passed fire tests at the Stennis Space Center before being mounted on a carrier.”

      True, there is one fly in the ointment in this barrel of honey: in May of this year, during the tests at the Stennis Center, one AJ-26 refused. But after that, fire tests of the modernized NK-33 were carried out in August in Russia. The tests were attended by representatives of Aerojet Rocketdyne. The engine worked successfully, there were no comments.

      the cause of the explosion was a defect in the turbopump

      According to this document, “The basic elements of the first stage, including fuel systems, are manufactured by the state enterprise Yuzhmash under the control of the Yuzhnoye Design Bureau. Both are in Ukraine. "

    “The useless Russian industry is to blame”

    As usual. It was the Ukrainians who modified the best American friends, and, as usual, the Russian industry is to blame, which, moreover, the same Americans "ripped to shreds." Something doesn't make ends meet.

    If someone reads my comments, then I very often talk about the limiting capabilities of these turbopump units and bearings. Only their work is limited by physical principles, and not by any other reasons. This means that the fight against clogging, defects and other things is a cover for their mistakes with a banal limitation in that they cannot understand the reasons for this and further accidents. Now that gap has happened. when a manufacturer of rockets and engines is unable to satisfy customers who are increasing their needs for the launch of large volumes and weight into space. A situation has arisen when the crowd of all joint institutions and designers is not able to solve a small technical problem just because everyone thinks they are significant and smart. And the "problem" doesn't give a damn about them all. This problem exists and will continue until it is comprehended and solved, "what is good and what is bad."

        Even in my thoughts I will not allow myself to name scientists and developers of rockets and engines with the word that you called. However, there is a process related to the evolution of knowledge. Sometimes it’s possible for centuries to improve some technical issues, but this will only lead to the limits of the extreme capabilities of the level of operation of these devices. Therefore, new devices are, first of all, an understanding of new physical principles and patterns that will expand the potential of new devices. For example, I watched the new DAYUNOV engine. Yes, this is really a new step in a new technical solution on how to place windings in email. engine, but this does not solve all problems and even more so does not allow to reach new levels of energy processes. This decision is in the status of energy efficient, but no more. But! We are talking about a cardinal principle that changes the entire energy of processes in a turbine. Therefore, their ability to breakthrough scientific and technical solutions does not depend on the number of scientists and engineers producing high-tech equipment or anything else. I would not even correlate this ability with the personality of a person. It’s just that someone’s brain reaches the parameters of such an effective work in analyzing and comprehending the experience of its predecessors that it produces something that defines this as the so-called

            Absolutely agree! And you correctly noted the "thin thread" that geniuses can only be brought up by a genius. But!!! Genius is the terminology of ordinary people, but in fact they are people with enhanced capabilities of the analysis mechanism and the choice of the correct direction for the use of these abilities. But again! Statistics show that geniuses "create themselves" after all. It is not for nothing that the proverb says that "only in the silence of a deep swamp do deep thoughts arise." And physics itself says about this that any explosive stage of the process is preceded by something that is not paid attention to, this is the compression and compaction of magnetic force processes.

      I will say that it is very difficult to link the solution of an extremely important technical problem of the operation of a critical unit of a rocket engine with what is related to Ukraine, Russia, or the United States. There is a regional scientific school, that is, it is a German school, which gave birth to the foundations of rocket engines, or maybe I'm wrong. There are American approaches, Russian, and now Chinese and Indian. BUT! At the same time, they all rely on the origins laid by the founders and creators of the first rocket engines and further fuel injection systems, etc. Therefore, the "foundation" must be slightly changed, and not corrected by "cosmetic repairs" and even more so to tie political or other ideological concepts to this.

    2. Russians generally have everything. Even elementary engines.
    3. The Russians cannot do anything normal.
    4. You need even more money to make your engine or to buy extreme Chinese.
    5. Our American specialists are still the best in the world, they found a defect in the blown up Russian bearing.
    6. We need more money, we need more money, we need more money ....

      Well, who said that the Americans do not have the same system of governing the people as the Russians. The Ukrainian authorities simply cannot and cannot control the people — that is, they have plundered the country. And so everything is the same everywhere. Moreover, in any country there are more than enough non-smart people in power.

    Yes, no one says that we have a different system. It's not about the system. This system is the same everywhere. Just if there is someone to blame for your headache, why not do it? And there is nothing for us to discuss such reports here. They are not written for us.

    I explain.
    1. The fact that the engines not only from the factory, they knew? They knew. Why didn’t they check and drive them properly?
    2. Suppose that a defective bearing can be found in a blown up engine. You can even prove that it was bad before starting the engine, but how can you prove that it was so? And precisely because of this bearing, the rocket did not fly? And not because of the fact that what that nigger John fuel pipe is not fully tightened. Or forgot to put the gasket? And didn't he put hamburger crumbs into the machine, which turned out to be "foreign particles"?
    It's easier to say that the engine was not ours. Like, we are not responsible for it. All questions to the manufacturer. The producer is far away. He lives on another planet. It’s cold there and hungry bears walk. And bribes are smooth from us.
    In any case, they themselves are to blame for the accident. Even if it's the engine. It was necessary to walk around the bazaar, look for a newer and more reliable engine.

      In fact, on the NK-33 there are control systems for all the main units and assemblies, with the conclusion of telemetry information to the control point. The bearing, for example, before crumbling, will necessarily warm up above the norm, which will be fixed by the control system. Another thing is that it is already impossible to change anything in the operating mode after the start.
      In general, I have already noted above about the "welded crack". If this is not a bluff, then there is nothing to be surprised. With a cracked engine, not even a single self-respecting motorist will sit behind the wheel, let alone a rocket engine!
