Military Review

Problems with A-400M engines were more serious than previously thought.

54
Airbus confirmed the presence of serious malfunctions in the operation of the gearboxes of engines installed on military transporters of A-400M - cracks were found in all engines whose propellers are turning clockwise, reports Look with reference to Defense Aerospace.




“This means that two of the four engines installed on each of the 24 aircraft currently delivered (a total of 48 engines) must now be repaired, which is a much more difficult task than originally thought,” writes the publication.

The article notes that "in addition to repairing the 48 engines of the already delivered Airbus aircraft, it will also have to redo the engines on the 20 aircraft that the company promised to deliver this year."

According to Defense Aerospace, "the company has already laid about 5 billion euros to solve this problem." In its report, Airbus called the problems with the engines "significant in economic terms."

In addition, "since the launch of the A400M program in 2003, its value has already increased by 8 billion euros - to 28 billion euros," writes the publication.

Earlier it was reported that "due to the weakness of the alloy, the aircraft had cracks in the attachment points of the wings to the fuselage." In addition, the report, published in the Bundestag, pointed out that the Italian manufacturer of blades "can not ensure the proper quality of its products."

The publication reminds that А-400М was developed by request of 7-s of states: Britain, Germany, France, Spain, Belgium, Turkey and Luxembourg.

      These are not miscalculations in the design, but already some kind of system is obtained: problems with the body, engines, blades. We still may not know about something.

        In an effort to reduce weight and reduce the cost of construction, modern engineers often go too far, and subsequently such flaws come up. Even modern computers with programs that simplify the calculations do not help, and sometimes they even do harm, because having trusted their capabilities, developers often refuse to conduct full-scale tests to save money.
        God forbid, something like this would have happened with the product of our design bureau ... would have already thrown poop
        On the Superjet, the error in calculating the strength of the airframe was compensated for by increasing the thickness of the skin. Many people know about it. The weight characteristics of the airframe have obviously deteriorated. But they didn't make a tragedy out of this.

      What are you talking about? 24 already delivered aircraft + another 20 for delivery this year, despite the fact that the aircraft was put into service in the 2010th year. How did this fucking shame pass the test? A golem drank dough in a European way, who needed to be given a paw, they shook hands, signed papers and this raw misunderstanding began to rivet.

      Is it the same with us? Who has it? Here, in general, the series has already gone. More than 20 machines have already been delivered to customers and put into operation. And such malfunctions should be detected either at the stage of testing the power plant, or, in extreme cases, during overflights of pre-production aircraft models. Immediately, the malfunction is revealed not by the manufacturer, but by completely third-party organizations. Moreover, the problems with the gearboxes of the power plants are still half the trouble, the happy owners of already sold aircraft and potential buyers of the machines that have not yet been delivered are equally worried about the issue of the discrepancy between the calculated safety factor of the power elements, wing and fuselage mountings. Defects in the form of microcracks have been found out there and there. And these planes have not yet flown the required number of hours, so that the defects that have appeared can be attributed to natural causes such as metal fatigue. Therefore, such an abundance of completely diverse defects, in the manufacturer's time-tested and mass of successfully flying models, smells of either the intrigues of competitors, or deliberate sabotage even at the design stages or pre-flight nodal tests. Or someone decided to save money on the supply of high-quality but more expensive alloys for the production of gearbox parts and power elements of fasteners, of course, all these versions of "IMHO". In any case, such flaws should be identified even before the launch of the model in mass production, so Airbus will not get off with billions in spending on fixing. Even more damage will be suffered by his hard-earned reputation, because he still produces non-trailed units for agriculture, where if the seeder collapsed and God bless her. You can always return a defective product back and buy another unit from competitors. Here, for this kind of manufacturer's flaws, customers will pay not only with their finances, but also with their lives, and most likely simply will not pay more.

            gear motors
            . This is in the first paragraph of the note. The cyclic engine speed is much higher than the cyclic speed of the propellers / propellers. Therefore, it is necessary to install a gearbox between the engine and propulsion unit. I apologize for the mentoring tone, but you need to be careful when reading the material.

        It is also seen that when viewed from behind, the rightmost and leftmost inner clockwise rotate. The fact is that modern mathematical methods of analysis do not allow an exhaustive answer to be given why rotation is necessary clockwise or counterclockwise. However, the answers may come from the fact that the same tornado vortex in the lower part rotates counterclockwise (when viewed from above). Moreover, there is no full understanding of where the energetics of the process come from. By the way, and when we look at the flame of fire, we see the plasma of a burning gas, and the plasma is always an intermediate part of the interaction of two polarized states - this is like a breakdown. Therefore, the direction of the plasma always has its very definite direction of the rotation vectors and longitudinal vectors. In other words, it is a complex of vectors and potential states inside the plasma itself. And the fact that the plasma has properties identical to the behavior of a hydro-gas-dynamic flow is proved by experiments in space laboratories and by Russian and American scientists astronauts. Therefore, it is quite clearly visible that the specialists of the aircraft building company completely do not understand the essence of the processes and do not own the methods of their analysis. And this is obvious that everything is done only experimentally, because the theory does not give the right to doubt its statements. In addition, many processes associated with flying at high speeds are associated with phenomena that are perceived as abnormal, but not as justified scientifically and mathematically. Here is such a short answer.

          That's right, but just the opposite. =) Although on the other hand, don’t look from where, the right wing will remain right, and the left wing will be left, as well as the engines located on them. Rotate the same clockwise and must be replaced, the leftmost and inner rightmost engines. ;-)

      Everything is somewhat different. In the desire to raise the parameters of engine efficiency, standard strength criteria are laid. In reality, in order to increase the thrust on the blades, you need to find a middle ground between the processes when the destruction of the blades and other parts begins and when you can achieve optimal parameters. Here is the bad luck. The dependencies are completely different. Engine power does not determine the efficiency of the blades as a propulsion device. And when you explain to people that, theoretically, completely different principles of the propulsion operation are needed, then established specialists turn in my direction at the temple. But! The military and customers are still demanding new and improved indicators. They "do not care" who is right and who is not. So it takes time for the aviators to agree to accept new theories and wing and engine designs combined with a propulsion system. And the materials in this case are not the defining problem.

      If they did it in the image of the An-70, then they would put 2 propellers on one engine and they would rotate in different directions. Our Tu-95s have been flying like that for more than half a century. I can't understand what kind of "bike" there is for 5 billion euros, did I really drink?

    It is clear that the aircraft is structurally new, something else, besides the falling off wings, will be found. But are the engines also completely new?

    Everyone is having problems. The main thing is to quickly and efficiently solve them.
    "The road will be mastered by the one walking!"

    And only the "great Ukrainians" are developing dynamically and are switching to "aggressive marketing"!
    Despite the fact that the Ukrainian aircraft company Antonov ceased to exist as a single de jure, its leadership continues to claim that this is “a new milestone in the development of the Ukrainian aircraft industry”. Such a statement in an interview with UNIAN was made by the vice president of the company, Alexander Kotsyuba. According to him, Ukraine is changing the strategy of its presence in the aircraft market and is moving to “aggressive marketing” (this is the term that Mr. Kortsuba personally used).
