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.


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


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

        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.

      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.

              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.

    They would give a glimpse of a scheme — such a stopper, or a large lock-nut! And so, without liters lol 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 ??

    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.

      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 .. wassat
    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. good drinks
