"This automatic reloading system is completely different from the T-72."

When you sit inside the tank, you can feel the biggest difference, which is the layout around it.

Whether it is the T-72 tank, or the 85 tank in China, or even the third-generation tank, the same automatic loader is used, two circles up and down, one is the warhead, the other is the propellant pack, when the automatic loading is made, the pusher pushes the bullet stick twice, and the warhead and the propellant pack are stuffed in.

However, the automatic loader of the T-80 tank was different, its cartridge was placed vertically, and the warhead was placed at the bottom at ninety degrees, constituting a unique layout.

At that time, the Soviets raised the caliber of tank guns to 125 mm, and at such a time, it was doomed that loaders could no longer be used, and, because of the high hopes placed on the T-64, they demanded a high rate of fire, and this automatic loader, which was designed by the Morozov Design Bureau in this case.

It adopts a crank slider mechanism to complete the lifting of the warhead and the cartridge, and uses the "meshing push chain" to realize the push of the ammunition into the chamber; after firing, the "shell collector" captures the cartridge and withdraws the shell, and after the second round is reloaded, the "shell collector" puts the shell into the cartridge box of the second round.

Compared with the transverse ammunition of the T-72 tank, its biggest feature is that it only needs to be loaded once, and the warhead and the projectile pack can be stuffed into it, and the loading step is completed with a swish of the projectile rod.

At the same time, it is precisely because of this? caused a lot of failures in the automatic loader, and in the beginning of the equipment of the troops, the failures of the automatic loader were endless? So much so that the officers and soldiers at the grassroots level would rather do it manually? I don't want to use this kind of chicken ribs.

Precisely because it is known that such an automatic loader is unreliable? That's why Kartsev will go the other way, however, over time? This automatic loader is also constantly improving? Mature, by now, it is considered very reliable.

Qin Zhenhua is watching the automatic loader inside? At the same time, I was looking at the structure of the entire turret interior.

Such a tank? Is there a turret gondola? This tank of the Soviets? What is the design? The turret is mounted on the hull? The turret basket is attached to the turret. The autoloader cartridge mounted on the turret basket is "hung" from the turret. Since the automatic loader needs to be in the same direction as the gun, this can ensure that the selector rotates independently of the turret and meets the functional requirements of the ball.

At the same time, it can also be seen that the lower cartridge and the warhead are placed in an "L" shape, with the cartridge being placed vertically and the warhead horizontally. Such? Wait until the time of operation? There will be a role of a push-pull mechanism. So? This means that the operation of the reloading process is complicated.

Just when Qin Zhenhua was observing the unique automatic loader? Wang Xiaoyu is also observing the fire control system, and she is here to observe the fire control system.

Sitting in this position? What attracted her attention the most, naturally, was the 1G46 sight, the size of this sight is very large, after opening the preheating, you can see the green light lens inside, there are many scales on it, when the tank starts, the scene inside the sight is motionless, it is independent two-way stability. She tried to turn it, aiming at the pitch range of minus fifteen to plus twenty degrees, and the movement on both sides was about an octave.

Then, when she removed her eyes from the sight, she immediately saw another device.

Thermal imager!

Who said that the Soviets had only tanks with infrared headlights? Of course, the Soviets also knew the importance of night warfare, and they were definitely not satisfied with more than just low-light night vision devices, as early as the seventies, the Soviets had already developed a prototype thermal imaging system for tanks.

On this tank, a thermal imaging system codenamed Agava-2 was installed, however, not every tank could be equipped with it, because the Soviet thermal imaging system was just starting, and its production was difficult, which led to high costs, so it was only installed on the command type of the T-80UD tank.

Although it is a night vision device and has a 384x288 pixel viewfinder, it does not use an eyepiece as a means of observation, but has a special display on the night vision device, and at the same time, the signal of this display can also be transmitted to the commander synchronously.

It is conceivable that thermal imagers are already inevitable for future tank night operations, and the big countries in the East must also seize the time to develop them! Now, although the third-generation tank has begun to be tested, there are still many problems in the fire control system that have not been solved.

Wang Xiaoyu adjusted this night vision device to the maximum magnification, although it is called a night vision device, but because it is a thermal imaging method, it can also detect the infrared rays of target radiation during the day, and the maximum distance is about 2,500 kilometers, which is basically the same as the range of a tank gun.

Wang Xiaoyu sighed in her heart, who said that the Soviet Union's electronic technology was poor? People's fire control systems also follow the trend of the West!

"Commander, do you have separate sights?" Signaling to Qin Zhenhua the thermal imager of the Soviets, Wang Xiaoyu asked about the situation on Qin Zhenhua's side again.

Whether the commander has an independent aiming device is very important, which means that when the commander finds the target, in addition to instructing the gun commander, he can also operate direct fire by himself, which greatly improves the speed.

Seeing that there were many viewing devices on Qin Zhenhua's side, and there were four periscopes, Wang Xiaoyu asked.

Qin Zhenhua put his eyes in front of him, and then nodded: "I think that I can shoot independently here, and I can see everything inside." ”

Then, he looked out and saw the special firing control lever on the right side, which was really tall enough.

The fire control system and sighting system of the Soviets are constantly developing, at the beginning, when it came to the T-80 tank, the PNK-4S universal sight was first used, it was only a small technological innovation, but the device pushed the T-80 to the same level as the best NATO tanks at that time, that is, it combined the function of auxiliary fire with the function of comprehensive observation, and the commander had all the operational authority of the fire control system, and directly replaced the gun commander at a critical time.

By the time of the T-80U, an independent stabilizer with its own gyroscope and compensator was added, evolving into a modern, universal commander-in-chief independent sight.

Just when the two people in the back were observing their own targets, Wang Erzhu in front had already started the engine, and the turbocharger at the tail let out a whistling sound, Wang Erzhu was wearing a tank cap and shouted to Qin Zhenhua through the throat transmitter: "The engine starts, please drive!" ”

"Yes, let's test the acceleration first." Qin Zhenhua shouted.

"Understood!"

The T-72 was a seven-speed gearbox, but on the T-80, it became five forward gears, pushing the gear lever into first gear, pressing the accelerator pedal, and with the roar of the engine in the tail, the T-80 tank jumped out.

The test run has begun!
