The tank gun can not only be lifted, but also can be pitched down, don't underestimate this depression angle, in many cases, it is still useful, for example, hide the tank behind the dirt slope, the tank gun has to dive relative to the hull, in fact, it can be hit flat.

In tank tactics, this is also a trick, whoever has a greater depression angle will take advantage of it.

In the previous tanks, the front and rear hulls were the same height, so the depression angles of the front and rear were the same, and the 59 tanks and 69 tanks on their own side were all like this.

However, when it comes to the current second-generation tank, it is different.

Advanced tanks need high-horsepower engines, and perhaps the engine itself is not very large, but after increasing horsepower, the heat dissipation problems brought about make the tank's engine tired, so it can only be equipped with a larger radiator.

At this time, if the front and rear are the same height, the space in the back will not be enough, so, in order to fit the engine, the back of the tank will be raised.

Now, almost the second-generation tanks and third-generation tanks are like this, especially the Western tanks, because the engine is more powerful, so the bulging of the rear hull is even more obvious.

You are having the same problem.

Engine compartment, to increase the volume, you have to develop to height, and what about tank guns? In the front, the depression angle is large, and the rear depression angle is small, and if you turn it back at the maximum depression angle, maybe the barrel of the tank gun will hit the hull.

This problem has to be solved!

As for how to solve the problem, it is necessary to work together to develop a mechanism for automatic cannon lifting, and when the maximum depression angle is turned over, when it reaches the back, it will be lifted directly! That way there will be no problems.

"Yes, that's what I think, Zhenhua, do you want to solve this problem together?" Zhu Lao asked Qin Zhenhua.

Qin Zhenhua shook his head: "I, ah, there are more important tasks. ”

"125 mm ammunition?" Zhu Lao asked Qin Zhenhua.

Qin Zhenhua nodded.

The task given to Qin Zhenhua from above, in fact, he still attaches more importance to it, after all, Qin Zhenhua has always liked tanks, and prefers the words left by his father that firepower is king.

With the acquisition of a T-72 in China, the choice between 120 mm caliber and 125 mm caliber has become a difficult problem, and since it is handed over to Qin Zhenhua, he has to be responsible for it to the end.

Moreover, there are still many uses for studying this thing, such as the return crisis encountered this time, Qin Zhenhua can use this to reopen the door of the other party.

Alas, a group of disgusting guys will do this kind of thing, and after doing it, they still have to wipe their butts, although Qin Zhenhua was angry enough at the time, and now, he has to find a way to solve the problem, after all, this is a major problem faced by a machine factory.

After saying this, there was a sound of footsteps behind him, Qin Zhenhua turned his head and saw Wang Xiaoyu with a somewhat nervous face.

"Zhenhua, I heard that you scolded the director of the Ma factory? And let them go? Wang Xiaoyu asked Qin Zhenhua.

Because it is necessary to develop a self-produced disturbance fire control system, which is also Wang Xiaoyu's graduation thesis, Wang Xiaoyu almost regards a machine factory as his own home, and many times he is here.

Today, when I heard about this incident, I felt that something was wrong, inquired about Qin Zhenhua's location, and asked him to come over and ask what was going on.

"Hehe, Xiaoyu, don't be afraid. This matter will not make a big fuss. Qin Zhenhua said to Wang Xiaoyu.

Now, everyone in the factory knows that Wang Xiaoyu is Qin Zhenhua's fiancée, and the relationship between the two is also very close.

Who would dare to retaliate? Don't dare to give them a dare.

"No, I'm not worried about you, I'm here to cheer you on." Wang Xiaoyu said: "You did a really good job this time, and many people in the factory are talking about it." ”

Come on?

Qin Zhenhua knew in his heart that he was doing this for the benefit of the factory, and of course those people had to support him.

It's just that if Ma Panshan and they really get out, Zhao Guodong comes to power, and he begins to really enter the core of power, then, a machine factory, there will be a more thorough change from top to bottom, and at that time, I don't know how many people want to scold themselves, at least, those guys in the R&D room will definitely hate itchy.

"Hmph, he Qin Zhenhua is getting more and more disagreeable, this tail is really cocked to the sky." In the R&D room, Du Youwen's voice was very loud: "This time, he must not let his conspiracy succeed, he wants to usurp power!" ”

"Yes, yes." Tang Chaoying, who is tall and tall, was also angry there: "He also said that he wants to be the director of the R&D office, if he is allowed to be, none of us will have a good life!" ”

"That is, he is alone, from morning to night, he is coaxing, just like a machine factory can't leave him, whoever the earth leaves, he has to turn the same!" Du Youwen said: "We have to think of a way, we must let him dispel this idea, Old Tang, what do you say?" ”

What to do? Tang Chaoying's hand, from the table on the side, suddenly pulled out a drawing knife and slammed it on the table: "Use this!" ”

With this?

Du Youwen was a little surprised, although we were a little dissatisfied, but this did not rise to the point of using a knife, right?

"That, Old Tang, should we use a more civilized method?" Du Youwen asked.

"Civilization? Is it now something that civilization can solve? He, Qin Zhenhua, used a barbaric way. Tang Chaoying said: "What, are you afraid?" ”

"What am I afraid of!" Du Youwen puffed up his chest: "I, Du Youwen, have never been afraid, since this kid first came to a machine factory, he has been arguing with our R&D room, this time, he will do him!" ”

"Okay, stick out your finger." Tang Chaoying said.

"What for?"

Du Youwen didn't know why, so he was grabbed by the big Tang Chaoying, and then, he felt a pain in his finger and stomach, and he was actually scratched open by Tang Chaoying!

Ten fingers connected to the heart, this time, Du Youwen was about to scream: "Old Tang, what are you doing?" You take a knife, there is a kind of stabbing Qin Zhenhua, why are you cutting my fingers? ”

"Stabbing? How uncivilized, we are going to write a blood book now! Tang Chaoying said to Du Youwen: "Your writing is the best, you can write it!" ”

You are paralyzed! Du Youwen wants to scold, you are actually this way of protesting, then cut off your own fingers.

"Quick, write, don't waste it!"
