At this point, Li Geng couldn't help but said sadly, "Sorry, manager, artillery is not my specialty. If Comrade Tan Zhigao can come, he will give you more professional advice."
Du Fei nodded.
In fact, he had no hope for tank guns. The biggest problem with tank guns was not the structural problem, but the performance of the gun steel itself.
If the quality of the gun steel is not good, it cannot withstand greater chamber pressure, and its power will naturally not increase. Relatively speaking, the threshold of the sighting system is the lowest.
Compared with the sighting system of the domestic Type 59 tank, the one used on the T62 is more complex and more precise. But in the final analysis, it is still a structural improvement. As long as you follow the gourd, you can always get something similar. Maybe the effect will be compromised.
But as Dufy said, at least it looks the same.
Du Fei immediately said, "In that case, let's start with the sighting system." Seeing that Du Fei was doing his best, Li Geng breathed a sigh of relief.
He was really afraid that Du Fei would act in his own way.
In the original unit, it was not uncommon for laymen to direct the work of experts, completely ignoring scientific laws, and ultimately causing a mess. Li Geng knew that Du Fei never went to college and went to work right after graduating from high school.
Although he admitted that Du Fei was extremely capable, he was convinced.
But I was only worried that Du Fei didn't understand technology and made decisions by taking it for granted. Now it seems that he was overly worried.
In fact, Du Fei has already had a plan in mind regarding tanks. No one knows better than him the complexity and technical difficulty of tanks.
Even if the current Type 59 tank is taught step by step and the drawings are given to the production line, there are still problems. According to normal development, it will take a few years to fully understand and mature.
The significance of Du Fei's existence is to use the portable space to enhance the characteristics of items.
How to get 100 points from a student who can only answer 60 points?
The easiest way is to copy the answers directly.
The problem now is that even if I put the answer there, I still can’t understand it.
The best way to solve this problem is to give an answer worth 120 points. Even if you copy some mistakes, you can still answer 100 points.
But it's not the time yet.
Du Fei planned to let Li Geng work on the sighting system first to see how far he could get it. By the way, he would also exercise the technical capabilities of the factory.
Wait for them to copy the finished product, and then use the portable space to upgrade and transform it based on it.
Doing this is far better than directly repairing and upgrading the sighting system that comes with the T62 and then copying it.
After all, it was something he made with great effort. Upgrading and transforming it on this basis would definitely make it easier to understand. As for the rest, Du Fei decided to wait.
The chassis and engine must be made by the tractor factory.
This shouldn't be too difficult. The chassis of the t62 is basically the same as the t55, except that the engine has been slightly improved.
Zhu Li also mentioned that Yang Tong, if he could be put to great use after the investigation, could just hand over the work of replicating the engine to him. However, Du Fei planned to take another approach when it came to the engine.
Because Zhonghua itself can produce the B-55 diesel engine for the Type 59 tank, the T62 engine is just an improved version of the B-55, and the technical difficulty is not that great in comparison.
But having said that, the technical difficulty is not very difficult. If you copy it, the performance will not be improved much. Therefore, Du Fei decided to upgrade the engine first and then hand it over to the tractor factory.
As for anything else, we have to wait until the two experts Sun Qiwei and Tan Zhigao arrive.
In short, if everything goes well, Du Fei hopes to have a decent T62 tank by next year. As long as it has comprehensive combat capabilities, it will be enough to achieve seven or eight of the achievements of the original T62. > Because the T62 tanks exported by Sugo have been greatly simplified, their actual combat capabilities are far inferior to their own version.
It was even nicknamed the "monkey" version of the tank because of the serious draw.
Therefore, the T62 produced by Du Fei does not need to be better than the original version, it only needs to be a little better than the monkey version. I came back from the 8270 factory and it was almost time to get off work.
Du Fei is going to come back and sort it out
Just take some information and go.
But at this time, he received a call from Zhao Yutian, "Hey, brother, the Tan Zhigao you are looking for has been found. He is at the 514 Farm of the Corps."
Du Fei smiled, it was obvious that Zhao Yutian was really interested in his matter. He had found him in just a few hours.
Du Fei said, "That's great! Brother Zhao, you can help me open a medical record and get the person here, no problem~" Zhao Yutian agreed without saying a word.
This matter was not difficult for him, and besides, he had just contacted Kong Lidong and promised to help him contact Professor Ma. When it was Du Fei's turn, he had to work even harder.
Du Fei asked again, "By the way, does Tan Zhigao have a wife or children over there?" Zhao Yutian was very considerate and had asked in advance, but he didn't.
After a while, he put down the phone and finally finished one thing. Du Fei was in a good mood. In the blink of an eye, more than ten days passed.
It’s Labor Day right around the corner.
The weather is getting warmer day by day, and everything is going well here in Du Fei.
First, Secretary Deng solved the personnel problem at the tractor factory in just four days. The next day, Zhang Xiangdong came to Du Fei, obviously more respectful and respectful.
This time he saw Du Fei's methods and energy, and he was secretly glad for his choice. Then Du Fei went to the tractor factory for the first time.
To be honest, I'm somewhat disappointed.
The scale of the factory is average, and the equipment is nothing remarkable.
The only thing worth mentioning is that as a former tank repair factory, the factory has a large number of skilled workers who have touched tanks. In the following days, Sun Qiwen and Tan Zhigao arrived one after another, and they were all assigned to Factory 8270 by Du Fei.
The remaining Yang Tong was also released on medical parole and was sent to the tractor factory by Du Fei.
Regardless of whether they deserve it or not, these three are all talented people with real abilities.
If he hadn't rushed at this time, Du Fei wouldn't have been able to find these three great Bodhisattvas in this place. At this time, Du Fei was standing in the third workshop of the tractor factory.
This place is specifically responsible for the production of tractor engines.
Although the Jingcheng Tractor Factory is small in scale, it has quite complete departments. It is not the kind of OEM factory that pulls engines from other factories and assembles them.
Yang Tong was wearing dark blue overalls and stood next to Du Fei with Zhang Xiangdong.
He was covered in a lot of oil, his hair was gray, and his face was old. It was impossible to tell that he was only two or three years older than Julie. It could be seen from his facial features that he should have been a handsome young man when he was young, but he has lost his appearance in recent years.
.But this does not affect his technical level.
After being fished out by Du Fei, he quickly got into working condition after a short period of adaptation.
Yang Tong knew very well that the reason why he came out was because Du Fei took a fancy to his technical ability. If he couldn't perform at his due level, he would have to go back and forth.
Every time he dreamed about it at midnight, he would break into a cold sweat when he thought about going back to that place. So Yang Tong rolled up like crazy without Du Fei urging him.
Work overtime every day until late at night on Sunday
There was no such thing. At this time, his eyes were still bloodshot and there were two dark circles on his face. Du Fei even tried to persuade him to rest more and avoid sudden death again several times. He was also afraid that if he let out his anger,
, I can’t bring it up again.
We can simply leave it to him, at least get the T62 engine out first.
At this time, the pile of parts in front of them was the engine removed from the T62. Next to it was the B-55 engine of the Type 59 tank, which had also been dismantled.
No one knew that when the T62 engine was transported with the tank site, Du Fei found an opportunity to put it into his portable space and repaired it using blue light.
Yang Tong hadn't come yet at that time.
When he arrived at the tractor factory, he saw a brand new diesel engine with better performance than the original T62 tank.
Although Yang Tong felt a little strange, he didn't know where Du Fei got the new engine. .??.
But he had participated in the design of missile engines and knew the confidentiality regulations. Don't ask questions that shouldn't be asked. Facing the engine that Du Fei brought, he just observed it silently.
Originally, he was interested in b
He was very familiar with the B-55 diesel engine. At first glance, this new engine was improved from the B-55. However, after testing the engine, he was surprised.
The original rated power of the b-55 was only 380 kilowatts, but the measured output power of this improved engine actually reached 450 kilowatts!
Without much change in the basic structure, the power has been increased by more than 18%. The original engine of the T62 has a rated power of only 420 kilowatts.
The task Du Fei gave him was to design a new tank engine based on the B-55 diesel engine and this upgraded engine. The final power must reach more than 400 kilowatts, be reliable and durable, and have a low failure rate.
This is not something Du Fei is forcing others to do.
Because after the transformation of the portable space, the original t62 engine has been greatly optimized, and the b-55 engine is the original. As long as you follow the gourd, it is not difficult to make it durable and reliable.
And in order to reduce the failure rate, Du Fei has made concessions in performance, reducing it from 450 kilowatts to 400 kilowatts. But Yang Tong still frowned after hearing this.
He knew that the failure rate of the B-55 engine, which was the basis, had never been solved.
This is not only a problem of machining accuracy, but also a gap in the materials used to make the engine block. But at this time, in front of Du Fei, he could not say no no matter what. Recalling that situation, Yang Tong secretly felt
Breathe a sigh of relief.
At least so far, it's been smoother than he expected.
There are drawings of the B-55, and they are adjusted and modified according to the upgraded engine of Du Fei. This step is more than half completed now.
The next step is to search for parts according to the drawings, produce parts, and assemble them. However, this is just the beginning.
There is no guarantee that the engine will ignite successfully when it is assembled for the first time.
Du Fei didn't know Yang Tong's inner activities, and after learning about the process of replicating the engine, he asked Zhang Xiangdong, "Director Zhang, how is the tank site going?"
After Yang Tong arrived, he was mainly responsible for the engine, and Zhang Xiangdong was responsible for the tank chassis. This is relatively simple, because the T62's territory has almost no changes from the T55.
Just take the chassis of the Type 59 tank and use it.
It's just that the original tractor factory could only theoretically switch to producing tanks during wartime. It had never been tried before. This time, it encountered a lot of troubles.
Fortunately, there is one at 8270 Factory Sun Qiwen is a great guy.
These problems are not difficult for Sun Qiwen, and he can help solve them quickly one by one.
Zhang Xiangdong said with a happy face, "Manager, we have produced three tank chassis here and are ready for use at any time." When he said this, he couldn't help but glance at Yang Tong.
Needless to say, Yang Tong's arrival brought a lot of pressure to Zhang Xiangdong.
Although Yang Tong's identity is not on the table now, his technical level is real. Zhang Xiangdong was originally a worker, and he was also a seventh-level fitter back then, so he knows technology. He is most afraid that Yang Tong will occupy the magpie's nest in the future and squeeze him away.
Therefore, he wanted to show his value in front of Du Fei. Du Fei nodded, quite satisfied with his progress.
Now as long as Yang Tong's engine is completed, the chassis will be completed. The other transmission and clutch devices can just use the Type 59.
The rest was the turret part that was handled by Factory 8270. Thinking of this, Du Fei couldn't help scratching his head.
The real problems lie here.
Li Geng is in charge of copying the sighting system and automatic shell ejection machine, and the other tasks are left to Sun Qiwen. Tan Zhigao is in charge of copying the 115mm smoothbore cannon.
This is even more of a problem.
Currently, the 115mm tank gun is the largest caliber tank gun in the world.
Western tanks generally stay at the 105mm level.
The main gun caliber of the Type 59 tank is only 100 mm.
You can imagine how difficult it is to suddenly increase it to 115 mm.
Moreover, the T62 in Du Fei's hands destroyed the main gun before the crew members abandoned the vehicle. Bring it to Tan Zhigao
A lot of trouble came.
After leaving the workshop, he returned to Zhang Xiangdong's factory director's office. Yang Tong still had work on hand and did not follow him.
Zhang Xiangdong made Du Fei a cup of tea.
"Manager, this is the tea tree grown in my hometown. Please try it." Zhang Xiangdong chuckled, nodded and bowed, which was quite a bitch.
He is a sensible person. Now that he has made a choice, there is no need to hold back.
Du Fei picked it up, took a sip, and said with a smile, "Old Zhang, you should also sit down. You have done well recently."
Zhang Xiangdong said "Hey", and when he heard Du Fei's praise, he felt relieved and sat half-assed on the sofa next to him. Du Fei said again, "We have to keep up our efforts. Lao Yang is engaged in technology, you have to do good logistics.
"
The smile on Zhang Xiangdong's face became even wider.
Du Fei's words classified Yang Tong as a technician, and at least for the time being, his position as factory director was stable. Zhang Xiangdong said, "Manager, please don't worry, I will definitely guard this part of the tractor factory for you."
Du Fei heard his expression of loyalty and said with a smile, "It's better to keep it safe. Lao Zhang, your ability is quite good, so you can't slack off."
Zhang Xiangdong kept saying yes.
Du Fei continued, "Three tank chassis are definitely not enough, and production must continue. In addition, the engine that Lao Yang is responsible for must be advanced as soon as possible. Don't be afraid of failure, and don't be too frugal. Funds are not a problem. If necessary, report to the company."
"
Zhang Xiangdong couldn't help but be stunned.
In the past, no matter what the unit, they all advocated saving as much as possible and working hard. I have never heard of people being told not to save too much.
But Du Fei knows that any technology is made with money.
If you only think about saving money and look forward and backward, you will easily make a mistake.
Just like an engine, no matter how much you tinker with it from the drawings, it is better to just build one. If you find any problems, you can find them and solve them one by one.
