The Pentagon detects a problem with the engines of F-35 fighters

91

Lockheed Martin's F-35 Lightning II fifth-generation fighter program is facing a shortage of Pratt & Whitney F135 engines used on these aircraft. This is reported by Defense News with reference to a statement by the US Department of Defense.


According to the publication, the two main problems with the power plants of the F-35 are the inability to timely service, as well as failure due to premature wear of the coating of the rotor blades. As noted, the problem with the blades leads to the inability to perform maintenance on time, since the amount of repair work increases.

The Pentagon called the engine trouble "a serious readiness problem." Given the current situation, if appropriate measures are not taken, then by 2022 up to 6% of the fleet of operated F-35s may be left without engines. However, as noted in the Pentagon, this problem can be solved within a few months, if "we do not postpone the matter on the back burner."

The Pentagon first noticed a problem with servicing Pratt & Whitney F135 engines at the beginning of 2020, and over the years there has been an increase in difficulties. As it turned out, the declared capacity for servicing up to 60 engines per year turned out to be overestimated, primarily due to the lack of qualified personnel.

To remedy this situation, the Pentagon enters into an agreement with Pratt & Whitney for additional maintenance of power plants, which should start working by July this year. The problem with servicing the engines will be resolved, but additional unforeseen expenses will be required.

            It seems like it should be made of coposites, not titanium for sure. Judging by the price, it is made of gold.
            It has already been said that the unfinished one was put into production. And designed for EXPORT. And to sell to vassals is not a problem, we will give a little push and that's it.

              Composite blades have not yet learned how to make, the temperatures and pressure in the last stages of the compressor are very high. The compressor turbine is even higher.

          Do not block.
          VSMPO and Boeing have agreed on long-term supplies of titanium products.
          https://www.interfax.ru/business/746851
          As a last resort, Americans will buy titanium from Australia and China.
          By the way, it turned out, unfortunately, easier and cheaper to buy a titanium rod (for the production of parts for the cylinder head of an internal combustion engine) in China than in Russia.

        The problem is that the plane was being whipped up. Faster faster to start selling at the expense of quality. The same is necessary in a brand new aircraft of a new generation, which in the troops for a week has already been cracked in the engine, as a result of which the engine exploded. The mind is incomprehensible. "Quality".
        ... The F135-PW-100 and F135-PW-400 had fewer major failures during development and test phases due to the lack of annoying lift fan issues, but some major failures did occur during actual use. In February 2013, at Edwards Air Force Base, a crack about 135 cm long was discovered in the turbine blades of an F100-PW-35 engine of an F1,5A fighter jet in the United States. This even caused the engine to explode. In June 2014, in preparation for takeoff at Engreen airbase in the United States, an F-35A fighter unexpectedly caught fire. The results of the accident investigation showed that the fire was due to a third stage fan blade on the common blade disc of the F135 engine. The high temperature caused by friction resulted in microcracks in the rotor blades, the cracks further expanding the range of faults, which ultimately led to engine ignition.

            Once I caught a video on the Internet, but could not record it. The Americans were very happy that the first Fu-35 was landing on an aircraft carrier. Someone from the service decided to take it off and put it on the Internet. This plane flies up to the aircraft carrier and is about to land. And the pilot does not sit down, hangs, but cannot sit down. What is the matter asks the leader? The pilot responds to the instruments, I am already sitting, but with my eyes I see that the deck is still far away. The leader was surprised. The pilot tells him - I will hang like this until the fuel runs out. Manager, no, of course, now we will help you. Do not look at the device, look at the screen. He began to look at the screen, where he was shown how much the aircraft's landing gear is above the deck. In general, they planted. The pilot was pulled out. Sweating. He said - thank God, how to fly it? After that, a year passed, first the malfunction was eliminated and the plane landed. Each time the plane throws out new tricks, as if it were working in a circus.

              Well, yes, it is served in such a way that the most complicated new plane throws out different tricks at the beginning. The first Su-57s just crashed. It's not easy to debug a 5th generation airplane. This is not an increase in the power of engines and missile range, but a change in approach.

        I think there will be no problems with service with the proper approach. The problem is that the engine itself cannot withstand the operational load, since it is actually an improved version of the F119. But the temperature was increased to 2200 C degrees Celsius. They tried to pull the owl onto a globe, saving money and time. In an amicable way, the engine needs to be created anew, either the design or materials must be changed, this option simply does not withstand the load, which was shown by its operation.
        ... Technologically, the F135 is a successful development of the F119 engine installed on the F-22. In March 2009, F119 reached an important milestone - its total operating time exceeded 110 thousand flight hours, these engines have shown their very high reliability and ease of maintenance by the technical staff. The F135 has improved engine system checks and failure detection. It has approximately 40 percent fewer parts than previous Pratt & Whitney engines, which also contributes to its increased reliability. All of its hot-swap components can be replaced with a set of just six tools. It requires 50% fewer man-hours to service than predecessor engines.

      The helmet has long been in the possession of the owner and the owner has no claims to anyone.

            Apparently, there are no critical ones, it was launched into series, unlike the F-35, which is still produced in pre-production batches. And that's a fact. So their "sounding" is absolutely irrelevant - they supply unprepared litak not only to their own army, but also expose the air forces of other countries to an unjustified risk. And yet - they did not sound nicherta, except for the total number of unacceptable problems - 870 pieces, and a couple of examples. And this is NOT funny, because because of these problems they have already died, and more than once. The Japanese have already dived over because of oxygen supply problems, so there are already murders on Lockheed. It's time to rename Loch Kid.

              There is no criticism, and the first production plane crashed on its first flight. The F-35 is not produced in pre-production, but in small-batch batches exceeding the entire order for the Su-57. An unprepared aircraft in the US Army has about 50% combat readiness among the delivered machines and 100% combat readiness in the IDF, and nothing has been said about the combat readiness of the only, second serial Su-57. Wasn't the pilot of the first serial Su-57 exposed to unjustified risk? Why are you not telling the truth. 871 shortcomings were announced. Of these, only 12 qualified as the first category and then two of them were downgraded to the 2nd. About 100 deficiencies are identified and corrected every year. Can you see the report which follows that the Japanese died due to one of the uncorrected flaws? Or are these your personal findings? And how, then, is it necessary to rename Sukhoi for a serial specimen that meets the ground in the first flight, in the absence of flaws? Who are you, an extraordinary bot? You fit this description much better than I do. Don't say goodbye, you are here in the parking lot, read it, you won't go anywhere.

At the same time, the bad and problematic F-35 has already been released. more than six hundred, is in service with eight armies of the world and has already been tested in a combat situation.

          Yeah, and he has not yet passed the state acceptance, but it is already in service and is being sold. What an incredible aircraft and technology that you might not even experience.

    One of the problems is that they are trying to make more planes, and the components for them are on a leftover principle, as a result, they are not enough during maintenance. With the massive supply of equipment to the troops, everyone has such problems. Remember the situation in the USSR with spare parts before 1941.

    due to lack of qualified personnel
    And what are they actually complaining about. If, instead of training engineers and qualified technical personnel, the priority of public relations is tolerance and comprehensive savoring of gender, homosexual and other perversions, then what do they want. I would not be surprised that soon (and even now), when applying for a job in the United States, the main attention will be paid not to special skills and profession, but to racial, gender and other characteristics. The main thing is not white, not male, not heterosexual. So I see that graduates of American colleges and universities, the diploma will not be written as an engineer, or a technician, but "gay of the first category", or "transvestite of the second level." laughing Say stupidity and insanity? ... But no. It is already an objective reality.

        Now yes. In American universities, most of the curriculum is already designed not for specialized subjects, but for "general education", such as "increasing the decisive role of gender diversity in public life" and the like. Taking into account the fact that a hundred different "genders" have already been invented, I can imagine what they teach there and what will be written there in the diplomas. laughing

    It remains for us to block titanium

    Do not block.
    VSMPO and Boeing have agreed on long-term supplies of titanium products.
    https://www.interfax.ru/business/746851
    As a last resort, Americans will buy titanium from Australia and China.
    By the way, it turned out, unfortunately, easier and cheaper to buy a titanium rod (for the production of parts for the cylinder head of an internal combustion engine) in China than in Russia.

    Smoothly on paper. Yes forgot about the ravines. The titanium ore of China, the deposits of which are located in China, is characterized by a rather strong contamination with elements that worsen the strength properties of the final products, and the lack of environmental control and production culture complements the overall picture of the presence of a large number of enterprises with low quality titanium rolled products and titanium products. cases when titanium rolled products obtained from China do not correspond to the previously declared characteristics in terms of properties and chemical composition. Disadvantages of Russian titanium: high price, long terms and a large minimum batch.

    China is a promising producer of titanium rolled products, the advantages of which are low price and production efficiency.

    Best use for titanium. laughing On February 11, 1992, off Kildin Island, in Russia's territorial waters, K-276 collided with the American Baton Rouge (Los Angeles-class) nuclear submarine, which was trying to covertly track Russian ships in the exercise area. As a result of the collision, the "Crab" escaped with damage to the wheelhouse (with ice reinforcements). The position of the American nuclear-powered ship turned out to be much more difficult, it barely managed to reach the base, after which it was decided not to repair the boat, but to withdraw it from the fleet.
    All submarine cruisers of projects 945 and 945A currently continue to serve in the Northern Fleet as part of the 1st flotilla

There is nothing good in this, because further degradation turns into decay, and this is the blood and death of billions of people. And you and me.
