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 is worth looking at it from a different angle, and what is it if 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" something on a 3D printer, first of all, you need to have it, and secondly, create a program for the manufacture of such a part, which means that having such a program and distributing it between repair shops, you can achieve both unification and speed in modernization

It seems to me that the F - 35 bears little resemblance to 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".

This is yes. And if you remove the existing operational restrictions for the F-35? Yes, and "nakolkhozit" still not really had time - the car is still relatively new.

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.

Do you even imagine the development and production of even a single part? Before it is put into production, hundreds of experiments are carried out, tested 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 assemblies are also classified (we will not even touch the patents). And now what John at the American airfield can easily restore all this? What the "kilometers" of money were spent on.

Quote: JD1979

Very strong, because this is the most raw materials, drawings of the blade, specification, production technologies, etc. - no one will, because it is secret and is intellectual property.

I do not argue.

Very weak, because 3D printing technology is not secret. 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?

Well then, why do all these "troubles" bother you? Business for 3 minutes.

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.

A turner with a milling machine operator makes the part according to the design documentation and TD, in which all calculations of the material and parts are already made by the designer.

It depends on what part, if loaded, I would like it to be turned, not sintered from powder.
One question: Why are the blades of the hot zone of aircraft turbines not printed on 3D printers?

They can't do that. And the hands for this are not sharpened and brains. If it is written in his technology that the nut must be turned with a "little white" wrench, then, in its absence, he will not think of using the "little black" key.

Alexey, you do not understand to which post my answer was. 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 of the key is simply not available, and the problem of repair needs to be solved no matter what. I am a TECHNAR myself, and in extreme conditions I had to use not only "black" keys, but also all kinds of home-made devices. When we were on a business trip abroad, we had to change the engine on the plane. It was sent in its original packaging with a factory set of tools, which, under normal conditions, settled somewhere in the rear economy. We're FUCKED. It turns out that all those works for the production of which we invented rationalization proposals, invented all kinds of "adaptations" ... were taken into account long ago and for each technological operation its own tool was "invented" a long time ago. So I mean that in the case when this "white" key is not available, the Yankes-techie will just sit on ... the opera exactly and wait for it to be brought to him, and with a certified certificate of validity, and Russian the technician uses what is at hand (sledgehammer, savvy and mother) and will complete the task of putting the equipment into operation. I don’t know if you understood me or not, but you tried to convey it.

[voyaka uh]

So I don’t understand you, sorry

And he will do the right thing. Because following the instructions is a direct path to a long and happy life, not darkened by reprimands from the authorities and conversations with investigators. For with a "little black" wrench, the bolt can be tightened with a different effort, or you can even tear off the head.

My answer was about Russian ingenuity, "sledgehammer and mother." What I mean is that in conditions when it is urgent to put the equipment into operation, and there is no "white" key, our technician will find a way to use the "black" one.

[faridg7]

That's for sure. This is the difference between our technician-engineer and the American technician. Ask why the bearing is clamped with a nut with a force of 150 Newtons per meter. Ours will most likely tell you about the bearing preload (unless, of course, he is a "minus engineer"), and the American one 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?

If something does not go as it should - think about it, read the TD, take advice, and do not show sometimes harmful "ingenuity"

[Piramidon]

Well, let him stupidly wait for this "little white" key from his state of Miami to be delivered to Europe. And our technician, with the help of "wit and mother", will already put the plane into operation.

I do not remember in which film the hero said - "orders are orders, and the fighter's personal initiative is also in the charter."
Yes, I am a technician, and I know how, sometimes, it is necessary to urgently release an aircraft into flight, but the very instrument that is needed according to all the regulations and instructions is not at hand. That's when you have to show ingenuity and initiative. But you, who is blinkered with instructions and instructions and under the threat of "sanctions" is afraid to retreat from them, will never understand this. Healthy nobody has canceled the initiative

[Grigory_45]

Quote: Piramidon

But to you, who is littered with instructions and instructions.

I don’t remember something to discuss your personality

Instructions are written for that, so as far as possible to exclude improper maintenance, which can lead to a lot of extremely unpleasant things. You will not deny this?
Second. There are many "rationalizers" who believe that they know better than designers and technologists how to "do the right thing", while TD and other waste paper is read only by "blinkered ignoramuses without convolutions in their heads." There will be a couple of examples on this matter at the end of the comment.
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 stuffed with electronics. For example, on the Audi A8, the parking brake is electric. And in order to change the pads, you need to resort to the help of a computer (dilute, and then bring the pads, setting "zero"). But why do we need high bourgeois technologies if we have a Russian sledgehammer? True, then the car had to be driven 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.

There is a crisis, it is a crisis in the USA as well, but there is also a fundamental problem: the F-35 was well ahead of its time, although there is no clear evidence that this is the "fifth generation" (well, that's okay). In any case, neither the security of the United States, nor the security of the US allies critically depends on the "diseases" of the F-35, and for the "cause of peace" this is even good.
