No matter what the UKR and the US plan, for Chen Nian, his task is the same.

That is, to export the key technology of the AGT110 heavy-duty gas turbine as soon as possible to ensure that Dongqi can develop and manufacture this significant gas turbine as planned.

Of course, in addition to this, he will use this gas turbine as a bait to guide Motor Sic to exchange as many chips as possible.

Their purpose may not be clear yet, but in the face of absolute interests, absolutely no one has reason to refuse.

After all, this is a super gas turbine with a power of 110 megawatts.

Compared with the technology of this era, its performance can no longer be described as rolling.

Whoever gets it will master the golden key of modern shipbuilding, heavy industry, and electric power industry.

Therefore, Chen Nian is very confident that the other party will definitely take the bait.

According to this plan, Chen Nian temporarily left Dalian and went to Dongqi Group instead. It happened that Deyang was not far from Chengdu. If there was any problem with the J-20 project, he could also go to the scene to solve it in time if necessary.

The Dongqi Group attaches great importance to him. Data, equipment, and manpower are all configured according to the highest standards. In some respects, his authority is even greater than that of the general manager.

In such an environment, his efficiency has also been greatly improved.

In less than a week, he had already sorted out the key technologies, and delivered the documents to the researchers below for preliminary verification.

If the verification is passed, the next step is to enter the stage of structure refinement and data preparation.

On this day, after finishing the day's work, Chen Nian took a walk in Dongqi Park to rest and change his mind.

While drinking the coconut juice specially obtained from Hainan by the logistics department the night before, he opened the system panel to check the latest harvest.

Since the main focus was on technology output, during this period of time, he did not place much weight on knowledge absorption, but even so, the number of sources was still growing at a steady rate.

In two weeks, a total of 1.76 source points have been added, and with the original stock, his number of source points has come to 2.99.

While he was looking at the panel, the number jumped up again, to 3.04.

It is estimated that another project has undergone technological fission, and contributed the source point to myself.

Now the growth rate of the source point has picked up again, and it is estimated that it will break through the 5-point mark in a short time.

So what should be the next technology?

For the Deep Blue 16 project, there must be some sources reserved.

After all, what he analyzed this time is only the self technology of AGT110, and those pre-installed infrastructure, materials, and equipment still need to be resolved one by one.

It is impossible to really pin all hopes on the Motor Sich factory.

Even if they have equipment and materials, it is impossible to fully meet our needs, at most it is just a foundation.

If you want to build a tall building, you have to do it yourself.

Electrolytic machining, directional solidification, electrohydraulic beam drilling, large precision CNC machine tools

These are issues that need to be addressed.

Thinking of this, Chen Nian secretly rejoiced:

Fortunately, the F119 was produced ahead of time, at least in terms of materials, there are basically no major problems.

Especially TBC.

For heavy gas turbines, this thing is too important

He finished the coconut juice in his hand in one gulp, and started to walk to his residence, and the moment he entered the red zone, the researcher who had been waiting for a long time immediately came up to him.

Chen Gong, you are back!

Chen Nian looked up and saw that it was the special contact person arranged by Dongqi for him who was in charge of all technical and life affairs during his stay in Dongqi. His name was Xu Yuan.

Uh, you're back, what's the matter?

To be honest, Chen Nian was still a little uncomfortable with this kind of meticulous care. For example, the night before, he just casually mentioned after the meeting that he would go to Hainan to drink coconut juice when he was free. As a result, when he woke up this morning, the kitchen Fresh coconuts are already placed in the restaurant, which has a feeling of no one knows it's litchi.

But this time, Xu Yuan didn't seem to be polite to him.

There is a problem with the technical team, I would like to trouble you to go and have a look.

What is the specific problem?

Chen Nian's expression immediately became serious. He knew that the general manager of Dongqi would not allow anyone to disturb him during this time after dinner, if there was no real emergency.

It's about the prediction of the thermosetting characteristics of the turbine blade flow. The technical team has seen the model you provided yesterday.

However, the results of their calculations are somewhat different from the results you gave.

Hearing this, Chen Nian frowned.

It's really not a small problem!

The so-called prediction of the thermosetting characteristics of the turbine blade flow, in fact, simply refers to the prediction of the working load of the turbine blades of the gas turbine.

At high temperatures, the continuously operating gas turbine blades are subjected to various loads such as centrifugal force, airflow force, temperature, etc. To ensure the safe operation of the blades, it is necessary to accurately obtain the operating conditions of the blades under the complex cooling structure.

Carrying out the research on the comprehensive characteristics of fluid heat and solid is the most basic means of obtaining data at present.

If there is a problem with this prediction, then in the subsequent R\u0026D and manufacturing process, the design characteristics of the turbine blades cannot be accurately realized, which may lead to the risk of shortened working life of components, decreased stability, and even the collapse of the entire gas turbine system .

How is it different?

Chen Nian asked quickly.

It's mainly about the heat transfer characteristics of the cooling structure.

According to the data and model you provided before, the technical group simulated the impact of three air film hole types, dustpan, conical and cylindrical, on the local cooling efficiency downstream of the hole row, but the final data results are completely different from your conclusion.

completely different?

Chen Nian repeated subconsciously, feeling extremely puzzled.

He carefully recalled the data he provided before, trying to find the key to the problem.

According to the model and results provided by the system, when the Reynolds number is 10000-25000 and the blowing ratio is 0.3-2.0, the best blowing ratios of the three hole shapes mentioned by Xu Yuan are 0.7 and 1 respectively. .0 and 0.5, and when the blowing ratio is greater than 0.7, the cooling efficiency of the dilated hole is higher than that of the cylindrical hole.

In addition, the contraction-expansion hole can also expand the coverage area of ​​the air film by forming a coupling vortex, resulting in a 110% improvement in cooling efficiency.

Chen Nian had done a preliminary check on this data before. After all, the model was ready-made, and it didn't take much effort, but at that time, he didn't find any problems.

Is it wrong to give the data?

Or is there a problem with the system?

possible.

After all, what the system gives is the final data, and the model is also generated based on the final data.

Could it be that this set of models is only suitable for AGT110 steam turbines?

That's not right. If this is the case, can the model still be called a model?

Chen Nian felt more and more puzzled, he hurriedly said to Xu Yuan:

Come on, let's take a look. If there is any problem, it must be resolved as soon as possible!

Understood, I'm waiting for you, I'll take you there now.

At work, Xu Yuan didn't have the hypocritical and obedient style of the agency, and the two of them quickened their pace and walked towards the laboratory.

While walking, Chen Nian thought to himself:

Hope nothing goes wrong.

——

But even if something goes wrong, it doesn't matter.

It is not for nothing that I have learned so many things.

If it's really something that the system can't handle, then I'll take care of it myself!
