This is really beyond Yang Fan's expectations.

In just one day, the Donghai Shipyard successfully installed the main gun. How is this possible?

Knowing the difficulty and cumbersome installation, Yang Fan is 80% sure that there should be a problem with the Donghai Factory and must be pointed out.

If there is really a problem with the installation of the main gun, in the future, if there is war in the vast sea, such a problem-providing main gun may cause the ship to be destroyed and people to be killed.

I was anxious.

I hurried out of my office and walked out of the office building quickly. I no longer had to go to the small bus shift to apply for a car to take me to the Donghai Shipyard, but drove myself.

After opening the car door and getting on the car, soon the Jeep off-road car let out a low growl, left the East China Sea Ship Design Institute, and headed towards the East China Sea Factory.

Someone happened to see this scene, and the invisible center tightened, and he thought a little worriedly, was something wrong?

Yang Fan didn't care what would happen if others saw it. At this moment, he only had the main gun that had been installed on the Donghai ship. The car was fast and arrived in front of the office building of the Donghai Shipyard in less than 40 minutes.

When there was a sudden brake, the tires and the ground made a sharp sound. The car almost stopped completely, so Yang Fan got out of the car.

He strided and entered the office building at a rapid speed. He quickly arrived at Chen Shaohua's office. As soon as he came in, he asked: "Old Chen, you have really installed the main gun. Tell me how it was installed at the beginning."

I didn't ask in detail on the phone just now, and Chen Shaohua didn't explain in detail. Yang Fan was not clear about the specific installation details, so I must ask now.

Feeling the worry and anxiety in Yang Fan's tone, Chen Shaohua, who was in a good mood, felt a little sank in his heart, "What, is there really something wrong?"

Yang Fan nodded and said, "According to my guess, 70% or 80% of them may be problematic."

What!

There is really a problem!

Chen Shaohua's heart sank again.

If someone else said there was something wrong with the main gun installation, he would definitely not believe it, and he would even refute that there was no problem with our installation. After the installation was completed, we carefully measured the relevant installation size, and the process error was within the allowable range.

But Yang Fan said this, the situation was different.

Who is Yang Fan?

His current identity is the assistant to the chief designer of the 052 ship. Putting aside this identity, Chen Shaohua knows very well how Yang Fan’s technical level is.

It's over, it's over...

It seems that it is a happy event, and there is something wrong with the installation of our main gun...

Chen Shaohua's heart gradually sank and almost reached the bottom of the valley. He already thought that there must be problems with the installation of the main gun, even if the relevant installation size has not been measured yet.

"What should we do now?"

Chen Shaohua asked anxiously, looking at Yang Fan almost with help.

What to do next?

Yang Fan's idea was very clear about this. The first step was to measure the installation size of the main gun and what is the specific installation process error.

He waved: "Let's go build the ship platform and arrange for personnel to measure the installation size of the main gun."

"Okay, then we'll leave now."

Chen Shaohua immediately agreed and left the office with Yang Fan. He soon arrived next to the construction platform. From a distance, they saw a lot of people on the bow deck of the 052 ship.

That seemed to be Zheng Xianxue, Li Chaolin, and there seemed to be the deputy chief construction engineer Xie Xinjian, who seemed to be saying something.

The distance is closer, you can see it clearly and confirm that it is them.

Chen Shaohua waved, "Let's go, let's board the ship and go to the deck of the ship."

On the deck, next to the main gun, in addition to Zheng Xianxue, Li Chaolin and Xie Xinjian, there were several technical and quality personnel, as well as several workers.

The main gun fell steadily on the installation base yesterday, aimed at the positioning hole and tightened the positioning screws, but a lot of the installation work has not been completed.

Today we will continue to install and install all the things, so that the main gun can be truly fully installed.

But in everyone's opinion, the first key step has been completed. Today's installation is almost no technical difficulty and should be completed smoothly.

Zheng Xianxue was a little worried. When he arrived here with Li Chaolin, he happened to meet Xie Xinjian, the deputy chief construction engineer who stayed at the construction of the ship platform almost every day.

Zheng Xianxue means to measure the installation size again and confirm again whether each installation size is within the qualified range of the process.

But Li Chaolin believes that it is not necessary. This move is a waste of time. The most urgent task is to complete all subsequent installation work.

Seeing Chen Shaohua and Yang Fan coming, they stopped this dispute.

Deputy Chief Construction Engineer Xie Xinjian said: "Old Chen, you are here just in time. Minister Zheng meant to measure the installation size again. You can make a decision to see if you really measure it again."

This is not easy to measure it once. Several technical and quality personnel have to be busy for more than half an hour because there are many installation sizes that need to be measured.

Li Chaolin also said: "Mr. Chen, that's too wasteful of time and it's completely unnecessary."

Chen Shaohua looked at Yang Fan, then looked at Zheng Xianxue, thinking to himself that Minister Zheng was also worried about the installation problem, so he went with Comrade Yang Fan.

"Comrade Yang Fan, what do you mean?" Chen Shaohua said.

Yang Fan looked at the main gun, then said seriously: "I think Minister Zheng's decision is correct, and I am also worried that there is a problem with the installation of this main gun."

What, there is a problem with the installation!

Li Chaolin retorted: "It is impossible to have any problems with the installation. After the installation is completed, we measured the installation size. It is completely within the range of process qualification."

The technical and quality personnel next to them also said almost in unison, "Yesterday, we measured it together, and there would be no measurement errors. The installation size at that time was completely qualified."

Yang Fan shook his head gently.

"With the qualification at that time, it does not mean that it is also qualified now. The steel plate of the 052 ship is thinner than the traditional warship steel plate and must be affected by temperature changes. As far as I know, the installation aperture of the main gun installation base is very precise, and the dimensional tolerance is very small, so the influence of temperature must be considered."

It's temperature again!

Some people involuntarily recalled the installation of the power system a few months ago.

The technical and quality personnel looked at each other and exchanged their eyes quietly, and saw the solemnity in the other's eyes.

It can be seen that they thought what Yang Fan said made sense, and then they felt a little worried.

Is there really a problem with the installation of the main gun?

Chen Shaohua waved: "Precaution is done immediately."

The chief construction engineer said this, and Yang Fan proposed the impact of temperature changes, these technical and quality personnel took the gauge and began to prepare for manual measurement.

Yang Fan raised his hand and said, "There is no need to measure all the installation sizes. It would be a waste of time. Take the drawings and I will tell you which two sizes to measure."

One of the technicians immediately spread the design drawings, and Yang Fan pointed to two important and critical installation dimensions and said: "Just measure these two dimensions."

These two sizes are very important.

There is a bracket behind both sizes, and the words "z101" and "z102" are marked in the brackets respectively.

The capital letter "z" is the abbreviation of an important size. As you know, if you mark this letter after the size, it means that this size is an important size.

These technical and quality-quality personnel looked at Yang Fan in admiration, and a feeling arose in their hearts.

It's worthy of being Yang Fan!

It's so amazing, I've grasped the key to the problem at once!

He seemed very familiar with this design drawing. After the drawing was spread out, he didn't have to look for it at all, and he pointed out these two dimensions at once.

This level of familiarity is really rare!

They looked at Yang Fan again with admiration, and then several people started to measure with measuring gauges. The scene became quiet and waiting for the measurement results.

Li Chaolin felt that he was a little inexplicably nervous.

Intuition seemed to be telling him that these two important installation sizes might not be qualified.

No, no.

We measured them carefully yesterday and found that they were qualified, so how could they become unqualified overnight?

Soon, the measurement results came out.

The leading technician, who was in charge, shook his head and said, "Mr. Chen, Assistant General Yang, these two sizes are really unqualified, this is the measurement result."

After saying that, he gave the recorded measurement results to Yang Fan and Chen Shaohua. The others surrounded him and their eyes fell on these two measurement results.

Really unqualified.

The process requires that the error between the main gun and the base should not exceed 0.2 mm. The error between these two important docking sizes exceeds 0.2 mm.

Failed!

Many people's faces changed, and their hearts sank to the bottom.

At this time, Li Chaolin had to accept it, sighed softly, and thought to himself that he was worthy of being Yang Fan. He said he was not qualified, but he really was not qualified.

Really good!

I was wrong, it was ridiculously wrong!

Li Chaolin lowered his head and showed a look of shame on his face.

As the chief construction engineer, Chen Shaohua was a little heavy and disappointed. He originally thought that the main gun was successfully installed successfully, but he didn't know that there was no problem, but there was a problem.

At the same time, I was secretly happy.

Thanks to Yang Fan!

If it weren't for Yang Fan, we would have thought the main gun was installed with qualification, but we didn't know that there was such a big installation quality problem.

The deputy chief construction engineer Xie Xinjian basically felt like this. While feeling fortunate, he held Yang Fan's hand with gratitude on his face, "Thank you, thank you so much!"

"If it weren't for you, we were still happy that the main gun would be successfully installed." Xie Xinjian was grateful and then humbly asked for advice.

"Comrade Yang Fan, since the main gun is installed in a non-compliant manner, what should we do? If we reinstall it, how should we install it again?"

Almost everyone looked at Yang Fan and waited for Yang Fan to give advice.
