It's all about the nut. The US Army has suspended the adoption of Apache helicopters

Acceptance of the Apache combat helicopters at Boeing has been halted due to the uncertainty of the US Army about the longevity of one of the most important elements of the helicopter, Brigadier General Thomas Todd said.

The army stopped accepting AN-64 Apache helicopters because of a sealing nut that looks “suspicious,” Todd says DefenseNews.

According to him, the nut is a critical element of the safe operation of the helicopter, as it holds large bolts, which, in turn, hold the rotor blades. Inspections have shown that the nut is susceptible to corrosion under the influence of climate.

The decision not to use the helicopter was taken by the US Army in February, Todd said. In March, the army notified Boeing that it would not accept AN-64E until the flaws were resolved.

The company has already analyzed the cause of wear parts, the update was approved by the army. The summer will begin testing.

In the Boeing edition reported that the main priority is considered the safety and reliability of products, the company continues to cooperate with the army, Sight

No Aron .. This is a hammer thread .. Well, and if you don’t have fun, it means that there is something in it. In a suspicious form.

Of course, disaster, the American military-industrial complex is showing itself from the worst side, do these stupid clowns not know about anti-corrosion treatment?

They know, they know no worse than ours. only they have not produced ANYTHING ETERNAL for a long time, which means anticorrosion treatment is an unnecessary increase in prime cost.

This is a catastrophe

A catastrophe is to write such articles. I, like a helicopter pilot, have the impression that the author saw the helicopter only in the picture, but has no idea what the design is. It’s necessary to write such nonsense ... Especially about the "sealing nut" ... Either cry, or laugh.

Under the guise of our turner ... then a bolt will be considered for another couple of million candy wrappers.

The legend about the FSB and the doping tests of the Paralympics will sound more correct.

Well, we didn’t collect it myself. I bought for a bottle of vodka, a nesting doll and a balalaika of a local toilet cleaner. but he personally poured that nut from a syringe.

GDP loves beer. And where there is a lot of beer, there is plenty of urine ... Well, how abundant .... There is only one GDP, but there are a lot of helicopter nuts, there is absolutely nothing left for aircraft and rocket.

Nut. Corrosion resistant. How unexpected!

So it must be made of noble metal. That we have the most expensive Platinum and make it out of it

And then they say that in our cars the bodies are not galvanized and rust ... here galvanization was regretted by the nut, apparently due to cost savings.

It seems like a long time looking for this. but as they found, for a long time they could not believe their eyes

[gukoyan]

So, because of one nut, a catastrophe can happen ...
And such nanotechnologies as titanium or the notorious stainless steel could not be used?)

[san4es]

It's all about the nut.

They studied material science poorly ... corrosion is a sign of an electrochemical reaction ... a pair of metals is not suitable ...

If you don’t have enough mind, equip it with a plastic plug,

Shhh ... don't tell me. Or did you decide to participate in the cut of the US defense budget?

[VALERIK_097]

Alex, if the nut is titanium, then it will gobble up the whole helicopter. Such insidious properties of this metal.

[Servisinzhener]

For some it will be amazing. But a similar situation happens not only with us.

[Strashila]

And that they did not design it for self-tightening, did not attach the washers or remove the bevels ... as if their tuda-syud screws rotate.

[Chills]

Maybe they hint at kickbacks?

[Herculesic]

They would give a glimpse of a scheme — such a stopper, or a large lock-nut! And so, without liters plainly do not understand! But the question is - before the scheme was different, instead of this nut was something else? Or have they recently begun to sculpt a marriage because of savings on pennies? How did they take turntables up to this point ??

[Graz]

Putin personally did nuts

[anjey]

As usual, just a job, Major Gayke, Putin personally awarded the extraordinary rank of colonel .., and a combined business trip with a vacation in Israel, on the basis of the air force ...

[Nyrobsky]

On a tricky nut, there is still a “bolt” in the form of a “ground-to-air” or “air-to-air” rocket. It’s better for Americans not to fly at all.

[gloomy fox]

and what of non-ferrous metal can not make it? Well, or at the end of stainless steel? Or galvanize this nut ????

Something ov rusts. F-35 in the area of ​​the root of the wing, Apache nuts rust. And a few years ago they showed how armored doors were rusted at ICBM positions.

Apparently everything rusts there under the influence of some kind of aggressive gas ... Even the name in the language is spinning ... How is it, "violinist"?

and sho is this a nut such that one is screwed onto several bolts?

It is called the rotor hub nut. It has nothing to do with sealing (as mentioned in the article). It is not screwed onto a few bolts, it is screwed onto the shaft of the main gearbox. And counter with three pins, pins with plates, and plates with two bolts each. Made of bronze, I have never heard of corrosion for the whole service ...

and what bronze? beryllium? Maybe the kids in China ordered it and here is the result ..
In addition to bronzes containing tin, copper alloys are actively used today, in which this chemical element is not. Instead of tin, the following are used as the main alloying additive in such copper alloys:

beryllium, which gives bronze increased strength;
silicon and zinc are elements that make the surface of a bronze product very resistant to abrasion and improve the fluidity of bronze, which is especially important for casting operations;
lead, which gives bronze resistance to corrosion;
aluminum, giving bronze worthy antifriction properties and high resistance to corrosion.

Yes, military acceptance should work like that, but recently the Yankees have just the opposite. good example of the F-35.
