The British Air Force has demonstrated the "special" property of the C-17 Globemaster III

28


The American military transport aircraft C-17 Globemaster III has been in service since 1993. Today it is in service with the armies of the United States, Great Britain, Canada and Australia.



Almost all characteristics of the aircraft have been disclosed to date. However, thanks to a recent video from Squadron No. 99 of the Royal Air Force of Great Britain, it became known, as they write in the West, about another "special" ("unique") property of the transport aircraft, namely, the ability to deploy thrust reversers on its engines directly in flight in order to provide fast descent from the existing height.

Typically, the C-17, like most aircraft, uses thrust reverser to deflect airflow up and forward, resulting in more effective braking when landing. At the same time, thanks to this function, the transporter is able to reduce the distance that it requires for a full stop to 900 meters or even less, which allows the aircraft to use relatively short runways.

On the ground, when the engines are idling, the thrust reversers also redirect the jet stream away from the rear of the aircraft, which is especially useful when loading or unloading through a ramp.

With regard to the use of the reverse of the engines in the air, it provides the fastest possible descent of the aircraft from cruising altitude. So, in the description for the video from Squadron No. 99 it is indicated that during the recent maneuver, called Reverse idle tactical descent, the plane dropped from 9 meters to 000 meters in just two minutes. At the same time, the military argues that for the C-1500, this indicator is not the limit of capabilities.



As soon as the reverse thrust is engaged in flight, the pilots ensure that the descent rate of the transporter is maintained by adjusting the position of the aircraft.

The low bow position required to maintain speed is part of the fast descent maneuver.

- explained in 99th Squadron - the only C-17 operator in the RAF.

Although the command of the British Air Force claims that the aforementioned maneuver is unlikely to be used in emergency situations. However, it can be assumed that this "special" property of a transport aircraft could be useful for a sharp decline during penetration into enemy airspace or even landing at airfields located on enemy territory.

    everyone will shoot down in case of war ... and the reverse will not help. the blockade of the Island will be effective.

      It is not clear neither from the article, nor from the photo, nor from the video how the Globmaster shields-reversers work (or at least how they look).

      Our Il-76 is another matter.

          Such a sickly, say, reverse, in comparison with the Il-76, the photo of the developed reverse shields of which I showed above Yes

        Because when reversing, only the outer contour is overlapped there.
        And the shields themselves remain inside the engine circuit.
        The reverse is organized according to the same scheme on Boeing-737s.

    And if the reverse does not shift back?
    Let's hit the ground from a height of 9000 meters?
    I think there are not many who want to use this maneuver.

      I think that's by design, a kind of brake

        This reversal in flight is not really a brake, but a method of landing on unsafe forward bases. To exclude the phase of approaching the airfield at a height within reach of MANPADS. Just an approach to the airfield at an altitude of over 6k meters and then a "steep fall" to take off.

        Nope, in this mode, he does not know how to backwards.
        In this mode, it flies only upside down, and then without a crew.

    We solve the example 9000 - 1500 = 7500 meters.
    7500: 120 (2 minutes) = 62,5 meters per second
    Is he falling vertically?
    I doubt it however. fellow

    With modern air defense, this is NOT IMPORTANT at 30.000 feet, 10.000 m. The armor will shoot down the C 17 lehko, but it is useful against the Papaus without air defense. C75 Divina will come in handy for these maneuvers. laughing

    However, it can be assumed that this "special" property of the transport could come in handy for a sharp decline during penetration into enemy airspace or even landing at airfields located on enemy territory.

    In Soviet times, the reception with a sharp descent to the airfield was called "Afghan Sunset" and was practiced by all pilots of the military aviation.

    The technique is indeed very useful and, if I am not mistaken, was used at first in Syria, while the broads were very close.

      The Afghan call is a little different, there is still a sharp turn in my opinion .. Experts will tell you

        The Afghan approach is a little different, there is still a sharp turn in my opinion.

        The choice of the glide path can depend on many factors, such as the presence of mountains. In principle, you are right, the approach is most often in a spiral. But, the main feature of the so-called. "Afghani Zakhod", namely a sharp descent with a maximum gradient and the launch of the aircraft to the landing glide path almost directly above the ground.

          In Bagram, the 4th turn began at a distance of 1 km and an altitude of 100 m. You need to calculate: When entering Mazar-i-Sharif At D = 12 km H = 3500, short-range drive D = 1000m, H = 500. Landing in the precision landing strip.

    Maximum cruising (ground indicator) in flight at low altitude - 648 km / h
    Landing speed - 213 km / h
    The option is certainly useful, the question is that the power elements of the motogandol have a margin of safety for such multidirectional loads, or then suddenly insufficient fatigue strength will pop up, if during the design this option was not included in the calculations ...

      I think no. Those. constantly using this "option" is probably not recommended. But, in case of danger, as was the case in Afghanistan, it would have been scored.

    It would be better to show the "Afghan method" of landing Il - 76. There, too, in three 90 degree turns, the airplane descended from 7 meters to the landing glide path. "Afghan takeoff" is also impressive, I never thought that such a "fool" could gain altitude at such an angle.
