American KC-46 Pegasus faced misalignment during testing

23

The Boeing KC-46 Pegasus, which the US Air Force hopes will soon become their main tanker, ran into a fourth serious problem ahead of adoption.


New troubles were encountered during the tests of the KC-46. In September, it was revealed that the fasteners that prevent slipping inside the cabin of cargo pallets are randomly unlocked, which leads to their expansion in the hold.

As explained in this connection by the Air Force, this problem is currently being resolved, it will take "about months". The indicated drawback, leading to the free movement of cargo, not only poses a danger to people inside, but also violates the alignment of the aircraft, which can lead to the most negative consequences for the car and crew.

The KC-46 was developed to replace the KC-135 Stratotanker and KC-10 Extender. Like its predecessors, it was created on the basis of the Boeing-767 civilian airliner. Pegasus is equipped with a modular cargo design based on push-in pallets. It allows you to carry both passengers and various types of cargo, including jet fuel.

The US Air Force plans to acquire 179 Pegasus aircraft, Israel intends to purchase eight more, and Japan - at least two.

    we’ll see how quickly they solve the problem, or they disguise it and will sell it like F-35 to everyone, they are Yankees

      New technology always has "childhood illnesses." Another point is that they must be disposed of before being launched into the series (for this and testing), and not during operation ...

        This is a little strange, the elder brother of KS-46 aka B767 tanker / transport is quite successfully operated in Italy. It’s even interesting that they made a lot of new things in -46th.

          They will adopt it - it will be clear. Or maybe a simple budget cut? lol

            Dear, you still want to say that boeing can do a lot of things? Due to circumstances, looking after the misadventures of 737MAX: they have already discredited themselves so much - the FBI will figure it out

              That's right, Tramp. The story of the 737MAX specifically tarnished the reputation. And having burned yourself in milk - you blow water all your life. wink

              Then I don’t know. But Israel urgently needs these Pegasus. And, anyway, we will redo these internals. Therefore, the delay is unpleasant.

      It’s hard to imagine so many tankers in the USA. Do they really have so many planes that need to be refueled in the air !? recourse

        hi For many reasons, Americans have always paid attention to the possibility of refueling in the air: in principle, almost all aircraft and some helicopters have the ability to refuel in the air. One slippery moment: usaf on the one hand and usn / marines on the other use different refueling methods and, accordingly, refuelers are imprisoned for both methods. Except KS-160, this one is only for sailors and helicopters

        But the article also says that this board is also created for the transfer of various cargo and l / s.

        First, they need refuellers to ensure the deployment and combat operation of bombers and missile carriers of the NAC in which case.
        Secondly, refuellers are required to enable the rapid buildup of tactical aviation groupings anywhere in the world (where there are airbases) - so that you can transfer another one to your borders within 2-3 days goals for democratization a couple of air wings, without bothering with obtaining permits to fly or land with refueling from countries along the route. And even in the blessed times of the Cold War, incidents happened - such as the refusal of Spain and France to miss the American F-111 during the Eldorado Canyon.
        Third, refueling tanks are needed by BTA - for global transfers in the case of the same rapid buildup of groupings next to goals for democratization.

    Something often began to arise problems with centering on new aircraft. One gets the impression that modern designers have given up too much to computer programs. And they, as you know, do not have any senses, or intuition, or talent. So it turns out that aircraft operators are at the helm, and designers of design programs are in design bureaus. And modern managers are none other than the MBA operators. The template, of course, is needed, but not in new products.

      There seems to be a primary problem with securing cargo, which is even more strange.

      If you read the article, and not just the headline, then the problem is not with the centering of the aircraft, but with cargo securing. For example, when taking off, the cargo will slide into the tail and that’s all ....

    It happens. In the 60s, near Khanty-Mansiysk shift workers worked at the rig. They were replaced by An-2, which flew to the prepared site. For their removal, it was necessary to do two flights. One “commander-ass,” decided to take out the brigade in one flight, which is twice as much as it should be. So instead of 15 people, he “loaded” 33 people who stood standing, clinging tightly to each other. in front of the cabin. Truly like a herring in a barrel. Pilots got into their seats, a team was stuffed, and the last two pulled a special “load-fixing” net behind them, which keeps the load from moving. So this commander flew more than once.
    “Drillers” are accustomed to such flights, it suited them, the flight lasted 30 minutes. In the "last" flight, they did not pull the net, like, so hold on. but to the words of the commander, you are ready, answered - "yes, let's go, commander."
    When taking off, due to sharp acceleration, the drillers sprinkled like dominoes into the tail of the aircraft. After separation, the plane sharply increased the angle of attack - “soared”, and an instant later “fell on the wing.” The plane was smashed to smithereens, the crew and drillers got injured and injured. That’s what the violation of the "centering of the plane" is. yes

      KS-46 has a slightly different problem: the standard system does not provide cargo containment under normal flight conditions. This situation is surprising in that for such a versatile aircraft there is already a normally functioning cargo securing system that has been tested in operation:
