US Marines called the flaws of the GAU-17 turret convertibles MV-22B Osprey

32

Convertibles are widely used in special operations of the US armed forces. Convertibles MV-22B Osprey (“Osprey”) give a special combat power to the hidden GAU-17 turret.


First of all, we note that in most US military operations, tiltrotor aircraft are used for covert landing of special forces and are used by the US Air Force and aviation US Marine Corps. Marines landed with the MV-22B Osprey during military operations in Iraq and Afghanistan.

There are aboard the Skopas and weapons. Previously, the M240 machine gun with a rate of fire up to 950 rounds per minute with 7,62 mm rounds was considered basic for convertiplanes. But since 2008, after signing the contract of the command of the Special Forces of the United States Air Force with the BAE Systems corporation, they began to mount RGS (Remote Guardian System) remotely controlled defensive round-fire systems.

This system is integrated with the 7,62 mm GAU-17 Minigun machine gun. It is mounted under the fuselage of the tiltrotor on an external sling. When the tiltrotor takes off, the turret extends from under the fuselage. Turret release time - 2 minutes. Also, in 2 minutes, the turret retracts when landing the tiltrotor.

The second pilot of the tiltrotor, acting as a shooter, performs aiming using a monitor, which receives a signal from an external camera. Then he controls the turret with a special joystick. Thus, the remote control of fire.

By the way, fire can be fired at a speed of 3000 rounds per minute, and the system rotates 360 degrees. Thanks to the turret, the second convertiplane pilot can hit enemy manpower at a distance of up to 1500 meters.

The need for a turret is mainly to provide protection in any direction. After all, you are not limited only to shooting from one side of the plane or just from the nose. You can shoot in any direction from the belly of the plane,

says Sgt. Ted Karp of the 1st Tactical Marine Corps Squadron.

However, the system has its drawbacks. Captain Craig Thomas of the Marine Corps believes that the turret, due to its weight, reduces the number of troops and cargo that can be taken aboard a tiltrotor.

In addition, the load on the co-pilot increases, which, in addition to its main responsibilities, must also control the fire. Some servicemen complained to the commanders of nausea and dizziness because of the need to continuously monitor the monitor at a time when the tiltrotor was turning and leaning:

From the need to constantly look at the monitor when maneuvering the tiltrotor begins to feel sick.

And in the command of the United States Marine Corps, they believe that the use of a turret provides convertiplanes with new opportunities that have not yet been fully explored and tested in real combat situations.

      In such a caliber, it is also almost useless. It should be .. although ... 12mm .. then there is a chance to get off the ground .. where there may be a dumpling or 14mm easel. It is better to provide for the possibility of shooting from the sides with personal equipment of the landing, no one will feel dizzy .. yes and optimal when several eyes are looking, and not just one camera. I'm not talking about the Mi-8, which with its on-board weapons can clear a non-residential landing site ... no matter what weapons the adversary has ..

        This is still not an attack helicopter, but a machine gun that will allow you to fight back in case of an ambush of a descent. A larger caliber would only increase the weight of the system. 1,5 km excludes the defeat of the rifle, except for heavy machine guns. And there are not many of them on the battlefield.

          Прежде чем писать такое, почитайте хоть про основы балистики. Калибр 308 win уже на 600 - 700 метрах теряет эффективность. По энергии, по времени полета пули и по отклонению. ... на 1500 метров пулю можно закинуть только "минометному". Попасть в кого-то можно только случайно.

            You look how they shoot from a minigun. Accidentally and fall, aim to the side. And the shooting will be from top to bottom. It is clear that most likely he will not even shoot at 1500, but at 800m-1 km. It is quite normal, while it will be almost inaccessible from the ground with return fire

              You look like a minigun shoot
              seen many times not in commercials. At 100 meters from a line of several hundred rounds, 1-2 hit the target. At 700 it will be a sowing of the football field. That is, to quickly and efficiently turn off the ATGM calculation will not work!
              The energy of the 308 WIN cartridge is 700 meters below 1000 J. That is, it no longer breaks through a helmet or bulletproof vest. Especially light armored vehicles.
              Bullet flight time at 700 meters 1.5 seconds. Deviations in the wind under a dozen meters .... Therefore, there is nothing to talk about any kilometers.

                Do you understand what you wrote? I will explain on the fingers wassat for an unprotected carcass when hit in the chest area, 120j is enough, for a head-200j, as you know, the head is bone. The flight time is 308win at 700m-1.13sec, at 989j. wind drift with a side wind of 5m / s at the same range of 1.53m .from up to tens of meters they took the figure, it is not clear.

        Minigun is quite an effective weapon, both from a technical and psychological point of view, due to its rate of fire and large ammunition base (heavy helicopters and tiltrotoplanes can take on board more than 10 thousand cartridges for a machine gun)
        And it’s much more effective than

        The minigun is designed to disperse those who dare to shoot from a personal weapon at a landing or tiltrotor (helicopter). He is not an assault weapon to suppress anti-aircraft defense)) Moreover, the aircraft data are used mainly by the ILC (as landing equipment for a site previously processed by other means) and MTR, and the chance that they will be confronted by a regular army division is negligible

          which is as much as 3 seconds of continuous fire .... then reloading forces of 4 - 5 people ... wassat

    Have you got an ad?
    The main disadvantage of such turrets: the impossibility of firing immediately before landing, during take-off and when the car is on the ground. And these are precisely the situations when the machine is most vulnerable. 2 minutes after take-off, it should be at an altitude of 500 - 600 meters and a fire of 7.62 caliber is not at all effective.
    Maybe someone offers to use this huge clumsy karamultuk as a ground attack aircraft or attack helicopter?

      I support your point of view, as long as this envelope is on the ground, it can be uncracked from the RPG and on take-off, while this turret will be put forward for 2 minutes, then it takes 6 seconds

        Turret release time - 2 minutes. Also, in 2 minutes, the turret retracts when landing the tiltrotor.

          The video does not show in which acceleration one phase of bringing the installation into combat condition is shown. Some more to open the hatches, power the system, start the electric motor, start the work of the sights (without the laser rangefinder, the entire ammunition will go to the sight), turn towards the target, search for the target in the viewfinder ...
          Hollywood in the video loves to show a lot.

      All of this is entirely possible.
      1. turret extends / retracts quite quickly
      2. possible landing without landing aircraft - with cables.
      3. landing takes place alternately - while one car is on the ground, others cover it from the air, then change places.

        1. How quickly the turret is put on alert (understand the difference with the advance?)? Written 2 minutes ...
        2. При такой высадке турель использовать нельзя из-за риска покрошить часть десанта. Да зависание вовсе не сильная сторона "Оспрея". Тем более при потери веса...
        3. Прикрытие десанта "Оспреями"? Вы кино обсмотрелись? Эти каша лоты должны сматываться как только высадили десант, как и Чинуки. Прикрытие это работа ударных вертолетов.

          and you watch the movie. A few seconds - readiness for shooting. In theory, the time to transfer this installation to the combat position is the time to work out the turret lowering drives, the readiness to shoot - plus the time to unwind the barrel block. All. No minutes can be there

          wassat this is exactly what Soviet helicopter pilots did in Afghanistan and American helicopters in Vietnam. Read the memoirs of participants in those events. While one group is landing, the second covers it from the air, then the groups change places. Once the landing is completed, the cars get together and go home.
          Quote: Dreamboat
          These porridge lots should be wound off as soon as the landing, like Chinuki

          you, apparently, are mistakenly convinced that when landing any large assault landing helicopters come one at a time and leave the landing point one at a time?
