Bathing iron horse. About factory tests T-90

19
Ability of modern tank to overcome water barriers is one of the most important components of its combat potential. Indeed, far from always the conditions can remain purely ground when the crew of an armored vehicle performs a combat mission. The task of forcing water barriers is relevant for the conduct of hostilities and is therefore actively practiced in the course of various exercises.


And so that the tank was absolutely sealed after leaving the factory, they are satisfied with a full-fledged "bathing" in a special technical pool of suitable depth. The tank with the help of special cranes is sent to the technical pool, which performs the function of a natural ford.

Leak tests are performed for 20 minutes or longer. At the same time, the depth of immersion of the T-90 tank (namely, it’s about the report TC "Star") is 5 meters.

The check helps to identify leaks, if there are any after the assembly of the armored vehicle. The elimination of leaks ends with a new “dip” of the T-90.

In fact, here it is necessary to take into account the Soviet standard: the tank hull can pass water in the amount of up to 5 liters for five minutes. However, modern tank builders are trying to keep out of the question about any leakage of the armored vehicle during its operation - complete, reliable tightness.

      provided by the creation of overpressure inside the tank. It has nothing to do with "tightness".

      However, modern tank builders are trying not to talk about any leakage of an armored car during its operation - complete, reliable tightness

      for me personally highly doubtful.

        After assembling the BMP in the pool, if there is a leak, then the military representative has all and sends the car for revision.

    But how does the driver navigate under water? Levers straight and full forward? It should then be a wide ford. And if narrow, then you can miss. In a real battle, the opposite side will probably be mined and no one will mine before the offensive. If cleared, then a narrow passage. How much will it be, ten, twenty meters? And if under water you have to go a hundred meters and go exactly on this passage? And if they hit right in the aisle, will there be a traffic jam? The tank from the conveyor is checked in a reservoir, and if the tank already has a run, will it pass the test?

      Moreover, this ford should be previously reconnoitered for lack of pit ditches, logs and other things that interfere with the passage.

      In a real battle, for sure ...

      ... no one (in their right mind if) will not force the river bottom.

      And if ... to search, for example, in Google - then there are a lot of answers to all these questions, partly even correct. Well, you can still think with your head ...

      Under water they lead by a compass. The tank will never go to an untested coast. They will be trained to overcome the water obstacle in the nearest fishing line / behind the bushes / per kilometer, and at this time the reconnaissance group will reconnoiter the crossing points, and motorized riflemen on their infantry fighting vehicles will cross by swimming and will keep “that” shore. If the river is small (when you need to manage with your own funds, without involving the high command), then most likely it will be so - on this bank "took aim", and then the levers went straight ahead (and the motorized rifles on the other bank are already waiting). If a global operation of the type of crossing the Dnieper, then tanker ferries will be dragged along, the first wave will be transferred to them, and while it is being destroyed, a pontoon bridge will be built over which reinforcements will rush.

      Each tank has a semi-microscope. When immersed in water, a azimuth is detected by a semi-microscope and then the movement is strictly in accordance with the selected azimuth.

      For those who want to have a clear tank in service for a sane price.

    Yes, with the help of OPVT (equipment for underwater driving of tanks), Soviet (and, for example, German Leopards -4 meters, American Abrams - only 2 meters deep along the bottom) tanks can regularly overcome water obstacles up to 5 meters deep. But in this case, I see a short "training (used on Soviet diesel tanks only when teaching underwater driving - in the combat mode of forcing a water barrier, a small-diameter air supply pipe is installed on the tank turret, which does not allow leaving the emergency vehicle through it)" pipe-hole on the turret, and the lower skewed edge of it sticks out half a meter from the water of the factory pool, so, in my opinion, the actual depth of this "test immersion of the tank" is less than 4 meters under the bottom (this, apparently, civilian reporters "heard the ringing, but they do not know where it is " winked )!
    PS The direction under water is maintained by a driver-mechanic using a gyrocompass (in tanks "borrowed", like an air compressor, from aviators), which is included in the instrumentation of his workplace smile The launch-alignment of the gyrocompass and the "drift" of the chassis of a particular tank is carried out on land, in preparation for overcoming a water obstacle.
    Underwater crossing of a river or reservoir is a "whole business", in all respects a complex and responsible event fellow , but not that immediately "gurgle and drove" - ​​so you can easily drown a combat vehicle and go to feed the fish yourself wink smile .
    In Soviet times, special engineering floating-diving tracked armored vehicles were created and mass-produced for reconnaissance of underwater routes for forcing rivers and lakes, and there are articles about them in the HE.

        hi They prepared them for descent from transports (because of their large draft "in the load") near the coast, so that they would go out on their own along the bottom to land. As far as I remember, the Nazis experimented with flexible reinforced air ducts at depths exceeding our current "standard" 5 meters!
        And also, as in the Union at that time, in similar trials, there were human casualties among the crews due to carbon monoxide poisoning and drowning. request
        As a result, these diving "troikas" really "surfaced" in the "first wave" of the attacking Nazi troops, crossing the canals along the bottom near the Brest Fortress in the early morning of June 22, 1941.

            Regarding self-deprecating "reflections", I don't remember exactly which of the ancient Greek sages (probably Socrates?) Said: "By expanding our circle of knowledge, we thereby increase the perimeter of the border with the unknown!", Something like that! Everything is relative. wink
