Report in the USA: F-35 program office has no plans to eliminate 160 deficiencies

The next report was released in the United States, which reports on the work done to identify and eliminate structural deficiencies in F-35 fighters. The document “On State Supervision: Defectiveness Report Metrics” tells us that the F-35 program office did not manage to cope with all the identified problems.


From the report, which was compiled at the end of February of this year:

To date, 883 project deficiencies have been resolved. At the same time, another 160 shortcomings were identified, plans for the elimination of which are not yet available.

The report also talks about this situation: pilots and aircraft technicians pointed out to manufacturers and contractors 448 additional shortcomings, but they were not reflected in the metric. The reason for this is the manufacturer’s refusal to recognize these 448 cases as examples of F-35 flaws. This, in particular, is about design flaws and ergonomics. In other words - about the convenience or inconvenience of the location of certain controls, blocks and nodes.

In a special protocol, it is noted that the office of the F-35 program sometimes consciously translates the identified technical problems from the categories of deficiencies, which should primarily be addressed, into less significant categories. This allows representatives of the manufacturing company to get away from the need to quickly eliminate those shortcomings that are identified aviation technicians and pilots.

As it turns out, the largest number of complaints from F-35 pilots is related to the software of the fifth generation fighter. Some software components are reported to be unstable, which manifests itself primarily when using the network parameters of the aircraft. Problems arise in the logistic plan - if necessary, timely delivery of spare parts. Recall that earlier this problem was already discussed in the USA. To solve it, individual details had to be printed directly in the formations of the Air Force - on a 3D printer. As the pilots themselves note: "Repair using parts created literally in the field."

    The success of the program is impressive. At such a pace, they will reach repairs with the help of a sledgehammer and some kind of mother.

      Or maybe it’s worth looking at it from a different perspective, but that it is not an element of the ability to repair and make changes in the field, which dramatically increases the speed of such repairs. In order to "print" on a 3D printer, first you need to have it, and secondly create a program for manufacturing such a part, which means that having such a program and distributing it between the repair shops can achieve both unification and speed in modernization

        It seems to me that the F-35 looks a little like the T-34 of the Second World War, which would make repairs in extreme conditions. Instead of increasing the speed of repair, they can get a massive “penguin fall”.

            That is yes. And if you remove the existing operational restrictions for the F-35? And they didn’t really have time to “farm” - the machine is still relatively new.

        This is not yet understood by people. There is an inertia of thinking: "a part must be
        grind on a commodity machine, mill on a milling machine, drill holes
        on the drill and thread. "
        And the fact that the Z-D printer does ALL this at the same time in one cycle without chips -
        does not fit into the heads.

                And what do you think, if the article says about the printing of individual parts, and you write about the whole product - AK, does this mean that you did not read the article or you read but did not understand or understood but not so? What do you think, if under the factory conditions blades for turbines are printed, then if you print them in the field from the same raw materials, will they be very different? The future lies with printers, especially in the repair of all small things.

Before it is launched into production, hundreds of experiments are carried out, checked under loads, vibrations, separately, in a unit, etc., then corrections are made and checked again. Based on the results of calculations and experiments, a specification is made and sent to production. And in the case of F-35, a lot of materials, technologies, parts and components are also classified (we won’t even touch patents). And now, what kind of John at the American airfield can easily restore all this? What "kilometers" of money are spent on.

A specialist of the company can come to the base with its own flash drive))) and materials, if this is very secret))), the main thing is that the equipment should be. Or do you think that the one hundred fastening mechanism of a technical key broken by a hand-held technician is so secretive that it is necessary to order this piece of duralumin or steel from the manufacturer when you make it yourself on a maximum day?

                    there, and a lot. Parts and assemblies that are not critical to the task. For example, the same seat backs, or brackets for blocks. Pipe holders, etc. Various casings, hatches and covers. All this can be easily printed, and not wait from the factory or look for Uncle Vasya a turner-milling machine operator.

                    3D-printed parts are available from Airbus A350 XWB, Chinook helicopters, Eviation Aircraft aircraft, Advanced Turboprop
                    uses printed parts in the design of its turboprop aircraft engines, while Stratasys Direct Manufacturing and NASA use 3D printing of satellite antenna mounts. The domestic VIAM (All-Russian Scientific Research Institute of Aviation Materials) made 3D models of a small-sized gas turbine engine for drones using XNUMXD printing.
                    AO Klimov is developing a promising helicopter engine, in its manufacture which 3D printing with metals and polymer structural materials will be used to the maximum.
                    Well, Stratasys needs no introduction.

          Alexei, you did not understand what post was my answer. It was about who, in extreme conditions, will show great ingenuity and resourcefulness. The fact is that sometimes there are circumstances when this "little white" key is simply not available, and the repair task needs to be solved no matter what. I myself am a TECHNAR, and in extreme conditions I had to use not only the "little black" keys, but also all kinds of home-made devices. Once, while on a business trip, we had to change the engine on an airplane. He was sent in the factory packaging with the factory tool kit, which under normal conditions settled somewhere in the rear farms. We are FUR. It turns out that all those works for the production of which we invented rational proposals invented all kinds of "ways" ... were long ago taken into account and for each technological operation, a tool was "invented" a long time ago. So I’m talking about the fact that in the case when this “little white” key is not available, the Yankes techie will just sit on ... operably and wait for him to be brought to him, moreover, with a certified certificate of validity, and Russian the techie uses what is at hand (sledgehammer, ingenuity and mother) and will complete the task of commissioning the equipment. hi I don’t know if you understood me or not, but you tried to convey it.

        And rightly so. Because following the instructions is a direct path to a long and happy life, not overshadowed by reprimands from superiors and conversations with interrogators. For the "black" key, the bolt can be twisted with another force, or you can even break the head.

          My answer was at the expense of Russian savvy, "sledgehammers and mothers." I mean, in conditions when you need to urgently put the equipment into operation, and there is no “little white" key, our techie will find a way to use the "little black one".

            That's for sure. This is the difference between our engineering engineer and American technology. Ask why the bearing is clamped with a nut with a force of 150 Newton per meter. Our most likely will tell you about the preload of the bearings (unless of course he is a "minus engineer"), and the American will say that it is written in the instructions.

        and he will very correctly do that he will not use left-wing methods, even if he thinks of it.
        We saw such crazy handles that hammered the bolts with a sledgehammer if they didn’t go (think, I took the bolt with the wrong thread - this is not a problem for a sledgehammer))), individuals who managed to dock connectors that are not mating parts according to TD (dad and mom - but this also does not matter if there is physical strength and a bit of zeal), which were checked by the old-fashioned method (for a spark) of electronic blocks on semiconductors. Do you admire these people?

                The second one. There are many "rationalizers" who believe that it is better than designers and technologists to know how to "do it right", and TD and other waste paper are read only by "blinkered ignoramuses without convolutions in the head." On this subject, at the end of the comment there will be a couple of examples.
                Thirdly, the manifestation of ingenuity is the flip side of poor software. When you have to resort to ersatz methods, is it probably from a good life? Ponder this before you take pride in being savvy.) Savvy is for emergency cases, not the norm of everyday life. If everyday life consists of it, then you have a very interesting life))

                Now a couple of examples.
                1. I had to personally observe when one young innovator, having made several unsuccessful attempts to unscrew the nuts from the fuel filter, came up with nothing better than to cut off the fuel pipes ... with a grinder) He did not think that it would be very light and the body. His colleagues had to use the wrenches for other purposes - in the form of a missile, in order to stop Prometheus.
                2. Some particularly entrepreneurial, without reading the technical literature, when installing car radios, for the sake of saving wires, they passed the second wire on the car body. And what is the mass! They did not hear about the bridge circuit for switching on the ULF, and laziness to read.
                3. Modern foreign cars are crammed with electronics. For example, on the Audi A8 the parking brake is electric. And to change the pads, you need to resort to the help of a computer (to part, and then to reduce the pads, setting "zero"). But why do we need high bourgeois technology if there is a Russian sledgehammer? True, then I had to drive the car from a special center in order to re-teach the brakes to work as they should, but these are such trifles ...
                What is it for? If you are a big-headed and arm-shaped, honor and praise be to you. Not all of them. For this, instructions are written. And most are highly encouraged to comply with them. The fact that in the West they comply with the regulations is the way it should be. This is called a production culture.
                You personally can do as you please - at your own peril and risk. If you accept responsibility for your actions.

    Mukhlezh structure of the US Defense Ministry with reports on the flaws of the "Flying Penguin" - seeds. The full finish is that the Penguin manufacturer Lokheed Martin flatly refuses to provide MO access to the database of aircraft system failures that are automatically collected as part of the FRACAS integrated IC - like we have all the information, but it's a commercial secret for you.

    In fact, Lokheed Martin behaves towards the USA as a sovereign country - an arms exporter, and it gets away with it.

    Honestly, I dislike America. But here the comparison is not in our favor. As an example - a filthy bucket instead of a toilet on board our strategists. So our attitude to the simple warriors is not better, and in some places - much worse.

They will be preserved upon receipt of the F-35 in combat units, and in the future may affect the effectiveness of the fighter during the fighting ....
    - It is known that the aircraft had problems with a gun having "unacceptable accuracy" and with flight control systems. At high angles of attack, the F-35B and F-35C tend to deviate from the course ....

    The crisis, it is also a crisis in the USA, but there is also a fundamental problem: the F-35 is far ahead of its time, although there is no clear evidence that this is the “fifth generation” (well, that’s okay). In any case, neither US security nor the security of US allies are critically dependent on the F-35 “diseases”, and for the “cause of peace” it’s even good.

    destroyers are the future. Not yet used to it, but it will be so
    organized logistics.
    2) Network software problems - this is the only aircraft with such software.

        This does not happen. Those who first started, they are the leaders in technology.
        Without picking with jambs do not move forward.
        The USSR lagged behind with electronics in due time and still this lag remains.

          Not true! Not always. The most egregious cases are the Wright brothers, the Lumiere brothers. The very same Chinese - 1,2,3,4,5,6 iPhones have slipped in and if they do not yet lead, then they are almost on a par, whether it will be further, who knows. As in sports - not always the one who started first, will be the first and at the finish.

    To date, 883 project deficiencies have been resolved. At the same time, another 160 shortcomings were identified, plans for the elimination of which are not yet available.

    pilots and aircraft manufacturers pointed out to manufacturers and contractors 448 additional shortcomings

    Figase! That's for sure: “No matter how you shout“ Guard! ”, And the caravan goes on” ... On the right road, in short.
    For some reason, it seems to me that they correlate with the Su-57, in this case - “less is more, it’s better” and “you go quieter - you will continue.” repeat

    Here I am on my computer, I’ll also count 200 flaws, although the worker is not bad ....

    And specifically what - not a single word.

    From the memory of previous articles: have the tires been strengthened to withstand not 5 extreme landings on an aircraft carrier, but 25? And on SU57 how?
    Did the stealth cover increase so that it can withstand ultra-speed for a long time? And on SU57 how?
    Air overload? Afterburner duration ???
    Fuselage wear in tense places ??? Overhaul period of parts ???

    We have it all fine on Su, everyone knows ....

    This is not yet understood by people. There is an inertia of thinking: "a part must be

    on the drill and thread. "
    And the fact that the Z-D printer does ALL this at the same time in one cycle without chips -
    does not fit into the heads.

      No problem. 3D printing is not a speed method, not for mass production.
      But with durability - everything is in order. And by the uniformity of the material - there are no equal.
      There will be no sinks, as when casting, no thermal stresses.
      Both put on missiles, and on passenger aircraft such
      the details. And the more complex the part in shape, the more profitable to use this method.
