Liu Ranran probably expressed her gratitude like having a good meal with Ye Zhou. In her heart, the results she could make were actually based on the new materials provided by Ye Zhou. So if Ye Zhou could not sign the results, then he had to express it through other ways.

But the way she expressed it was indeed a bit embarrassing.

But Ye Zhou didn't care too much. He always had to find someone to have a meal, so there was nothing wrong with talking to her.

So, the lunch was finished in such a slightly awkward but also a bit of sincerity.

Ye Zhou did not take the brief contact between the two of them to heart. After returning to the office for a short rest, he came to the core development department of the factory, greeted several team members, and connected to the computing terminal to prepare for the work he had been preparing for a long time.

After the terminal screen lights up, a huge simulation system starts loading.

matrix.

This is an important achievement he has obtained from the simulated plot of the Dragon Heart, and it is also one of the technologies that can play a decisive role in future aeroengine design.

With this system, most of the test runs of aircraft engines in the future can be moved from reality to virtual, and there is no need to conduct actual production at all. You can directly input various parameters into the system and assemble into a complete engine, and then conduct test run simulations based on preset conditions.

This is a technology that transcends the times. If it can be used in full, it will essentially change the aviation industry pattern of the entire world.

However, in order to truly play the full functions of this software, Ye Zhou still faces two major problems.

First, the computing power of existing general-purpose computers is far from supporting the matrix for full-module simulation. They can only be simulated in a small range and a single functional area at most, and their functions can not exceed 5%.

Secondly, the simulation and calculation of the matrix rely on strong artificial intelligence. Without strong artificial intelligence assistance, the parameter adjustment can only be achieved by artificial experience, and the analysis speed is extremely slow and the efficiency is not high.

However, even if it is just the current "not high" efficiency, it has done enough for Ye Zhou.

What he wants to do is not a full-module simulation, but a quantitative simulation of microstructure evolution based on inherent parameters. The goal is to figure out the performance status of several core thermal components in the engine under extremely high temperature conditions.

After seeing Ye Zhou, the members of the temporary group had already come over, and one of them said:

"Mr. Ye, we have inputted the data we obtained from each workshop before into the system. We did the first trial run in the morning. The parameters are basically correct. The next step is to conduct intensity simulation."

“What are the structures involved at present?”

Ye Zhou asked.

"The main parts are the wing tips of the turbine fan blades, the axial force long screws, the high-pressure turbine rotor, the torsion gear rod, and the turbine guide blade."

“Have the simulation content been set up?”

"It's set up, there are 4 analyses in total, temperature, pressure, static blade position angle, oil chip pulp and spectrum."

Hearing the other party's words, Ye Zhou thought for a moment and added:

"Add a speed and vibration analysis on the spindle. This is the first time we have used a large-scale superplastic forming process. The performance is not stable, and the temperature and pressure are not a problem. What I am worried about is that excessive margin in material processing will lead to a decrease in accuracy."

"I understand Ye Gong, I will set it up right away. But if we want to add this content, we have to remove the spectrum analysis, otherwise the computing power will not be able to hold on."

"Then take it away. This test is relatively difficult and can be left for the ground for the interview."

"OK!"

After a simple reply, the group members quickly entered the parameter setting work, and the first simulation was completed one hour later.

Ye Zhou looked at the results presented on the big screen and frowned.

broken.

Literally bad.

In the final result analysis chart, Ye Zhou was most worried about the torsion gear rod, but there was no problem with the wing tip of the turbofan blade.

According to the preset conditions in the simulation simulation, the fan blades only worked less than 620 hours before severe creeping. During the last test run, even when the speed reached the rated standard, the wingtip was directly broken by the powerful centrifugal force at supersonic speed.

What's going on?

According to the design standards of an aircraft engine, the total life of a commercial aircraft engine must reach at least 40,000 hours. Even for high-intensity military aircraft engines, the life surface must reach at least 4,000 hours to be considered qualified.

However, if we look at the results in front of us, the lifespan of this engine's fan blade cannot even reach 200 hours.

After pondering for a while, Ye Zhou spoke:

"Simulate it again to see if it is an unexpected situation."

The team members started the simulation again after hearing this. The wingtip was still the problem this time, but it had been for more than 1,000 hours.

Without strong artificial intelligence assistance, the matrix system cannot make a judgment on the influencing factors of this result. In other words, it can tell you which part will have problems, but it cannot tell you what is wrong.

The pressure instantly came to Ye Zhou and the group members. Several people sorted out the parameters from beginning to end and confirmed the accuracy of the parameters again.

There is no problem with the processing technology, no problem with the accuracy, and the tolerance is within the design tolerance range of ge-9x...

The only thing that may be wrong is the material.

Ye Zhou asked:

"Did you use the latest batch of super-plastic-shaped fan blades?"

The team members nodded quickly and replied:

"Yes, because the parameters of the fan blades made by the new material have not yet come out, we took the parameters of the last batch of titanium alloy fan blades. We took them directly from the workshop, and all the parameters are definitely 100% accurate."

"Then why does this happen? The material composition of the torsion sleeve tooth rod is almost the same as the material composition of the wing tip, and it is under greater pressure. Why is there no problem with it? Instead, the fan blade that has actually been tested so many times has problems."

Hearing Ye Zhou’s question, all the members of the group fell silent.

They had no answer in their hearts.

Ye Zhou looked through the parameters and simulation results over and over again, and had actively activated the decision-maker's talent in his mind, but he failed to grasp any clues.

"When you took the parameters, have you confirmed with the workshop that the parameters come from the good fan blades? Have you measured the purity of the material? Will it be that impurities are mixed in the processing process?"

"There is no problem with purity after testing... Wait. If there is any problem with the material, the materials of this batch of fan blades are really different from those of the torsion-transmitting gear rod."

"Why?"

Ye Zhou's eyes left the screen and raised his head and asked.

"This is the latest batch of titanium alloy fan blades. It is made of the latest titanium alloy from the factory. However, the torsion gear rod has not been remade many times because of its relatively fixed structure. It is still the titanium alloy in the previous stock. Do you think...will it be a problem with this batch of materials?"

Problems with materials?

Ye Zhou's heart suddenly jumped.

Indeed, after all other possible factors were ruled out, the material became the only object of doubt.

According to his knowledge, if there is a problem with the composition of the titanium alloy, which is the main material, it is indeed very likely to lead to a reduction in the life of the turbofan blades.

But the problem is that all the high-end titanium alloys used by Liming Aviation Engine come from Baoti Group, and there has never been any problem in history. Judging from the inlet and exit records maintained by Liming, there is no possibility of being dropped or other destructive elements being mixed in the middle.

If there is a problem with titanium alloy material, then there is only one answer.

There were problems with this batch of titanium alloys before entering the factory.

Thinking of this, he immediately picked up the phone, answered the materials laboratory and said:

"I am Ye Zhou. Please organize an inspection of the latest titanium alloy materials that have been put into storage immediately. I now suspect that there is something wrong with this batch of materials."

"Yes, find some titanium alloys that were put into storage for comparison. I don't care whether this batch can meet the standards or not. As long as there are differences between the previous batch, I will notify me immediately!"
Chapter completed!
