In later generations, the 96 tank went to participate in the competition, but the Russians were slick and did not allow school guns to participate in the competition. The Russians calibrated in advance, but the 96 tank did not. As a result, the 96 shells kept off the target, and the Russians could just claim that they could not claim to the public.
, I saw it, the 96 tank is not accurate!
In order to promote their own tanks, it is indeed cruel enough.
Now, the other party uses the school cannon as a high-level step, deliberately displaying it in front of everyone, so that they know that advanced equipment needs to be calibrated by advanced professionally before it can be used.
This professional school cannon is divided into ten steps!
"Hardware inspection!" The first step begins.
Someone got into the inside of the turret and opened his eyes wide and checked. A cannon weighs several tons and is fixed by pillars and trunnions. If some small wear and tear occur here, it will
It affects the accuracy of the artillery, after all, the reason why it is a slight mistake is obvious here.
Open your eyes wide and check it out!
"Start pressurization!"
The turret of dozens of tons cannot be manually cranked. Everything depends on the tank's hydraulic system. At this time, the tank hand that had been inspected sat in the gunner's position and began to turn the fire control handle.
The tank's turret began to rotate as the tank's hand operated. While the turret was rotating, the barrel was still rotating up and down. In this way, under the gaze of everyone, he turned twice.
When the turret turns, you can see the proportion of the huge turret.
The 85 tank is also a welded turret, but the turret is not big and very small. In comparison, Western tanks are all big turrets, so the internal space is quite abundant. As for which one is better, it depends on the army.
I like it.
Now turning is because these are driven by hydraulics. During the rotation process, even if the hydraulic system has been preheated, the turret rotates, the main gun moves up and down, the hydraulic oil inside begins to move, so the hydraulic oil is considered
The pressure is completed, especially the bubbles that may exist in the hydraulic oil will also disappear during the activity.
“Detection of zero drift.”
The commands were shouted one by one, Derek's face was full of pride, he glanced at Qin Zhenhua, and then said: "Zero drift, this is an important aspect of morning error, but the previous fire control system could not adjust these things at all.
.Mr. Qin, do you know what zero drift is?”
The teaching exam has already started.
At this time, almost everyone present didn’t understand. This is too complicated, right?
"Drift is a concept in the circuit." Qin Zhenhua said: "If an electronic signal has an error during operation, it is called drift. It is like when we use a loudspeaker, the sound changes tone because the signal drifts.
, If we talk about the school cannon, the bubbles inside the hydraulic system can also be regarded as a factor of drift."
It was straightforward and accurate, and it was quite correct, and it was easy to understand. Mahmoud nodded: "So that's the case!"
Derek felt a little disappointed if he didn't take the exam to teach Qin Zhenhua. At this time, Qin Zhenhua asked again: "Your school cannons have such complex and professional movements. So, after such school cannons, it should be quite accurate, right?"
"That's of course." Derek said: "Only this most professional school cannon can ensure accurate shooting of the cannon."
After saying that, he glanced at Qin Zhenhua again, as if he was saying, your fire control system is too simple, let you see the professional ones now.
He didn't notice that an undetectable smile appeared on Qin Zhenhua's face. Humph, you can't hit it accurately after a while. Then let alone the lack of calibration. You have put such a big frame in the calibration now, but let's go again
I can't find this reason.
Qin Zhenhua stood under the tree and looked at the tank that happened to be blocked by the shade of another big tree. If you can calibrate it, then it would be a hell.
If the army came, they would definitely not make such a low-level mistake. After all, the US army is stationed around the world. How to do it in tropical areas is very experienced, but the technicians from these factories are different.
, Perhaps they think their skills are the most skilled, but they lack practical experience.
It is easy to adjust the drift. There are two correction knobs on the main sight board, "parallel" and "vertical". Just twist these two knobs and look at the output.
It was passed quickly. These steps were not available to other tanks. Now, the artillery pillars have been checked without cracks, the hydraulic system has been preheated, and the "drift" has reached zero position. The tank hand held the button on the fire control handle.
.
At this time, it is fully automatic, the turret will rotate back and forth, and the computer control panel continues to display step by step self-test, which is almost the same as the computer startup.
Soon, this step was completed. The old data inside the computer was cleared and replaced with various basic data here. Finally, the preparations for the school cannon were completed.
That's right, after doing so much, it's just preparations for artillery calibration. In this era, most of the artillery operation, which eliminates all previous operations, starts directly from the next step.
At this point, everyone understood it. A technician stuffed a device into the muzzle, then placed his eyes on it and shouted loudly: "In front, on the hillside, next to a house."
That telephone pole!”
On the hillside? The distance on the hillside over there is already more than 2,500, right? Even the other party chose such a far target as the standard. So how far can such a cannon be hit?
It seems that two thousand meters are perfect!
Even if he was replaced with a 105mm gun, the combat distance was limited to about one thousand meters because he used a light spot injection fire control system. Now, the opponent's electronic technology is indeed advanced enough.
The other party was showing off, and Qin Zhenhua sneered in his heart. The more awesome you pretend now, the more stupid you will be. You may also have to escape the target of a distance of 2,500 meters or 1,000 meters.
This step is something that many people can do. From the time of World War II to the present, this special "muzzle viewing axis correction device" has been used.
Insert this device with the abbreviation MBD into the muzzle, then place your eyes on the eyepiece, and use gestures and commands to collaborate with the gunner to correct the main gun. It can be said that it is the core of correcting the main gun.
In fact, it sounds very simple. When you insert it into the muzzle, make sure that the target is aimed at. Then, the gunner inside the tank locks the same target with the sight, so that the sight and the tank cannon can be guaranteed to be
Coaxial.
However, this is the advanced nature of the M1 tank. It is automated. After manual calibration, let go of the target and lock the target in the sight. The crosshairs in the fire control system can be automatically pressed on the target again.
.
Unfortunately, it is impossible to see from the outside, so everything has to be introduced by Derek. This automated operation is also quite high-end.
