No matter what UKR and the US plan, for Chen Nian, his task is the same.
That is, 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 also wanted to use this gas turbine as bait to guide Motorsic to offer as many chips as possible in exchange.
Their purpose may not be clear yet, but in the face of absolute interests, there is absolutely no reason for anyone 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 crushing.
Whoever gets it will have the golden key to modern shipbuilding, heavy industry, and 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. Deyang happened to be far from Chengdu. If there was any problem with the J-20 project, he could go to the site to solve it in time if necessary.
Dongqi Group attaches unparalleled importance to him. Data, equipment, and manpower are all configured according to the highest standards. In some aspects, 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 completed sorting out the key technologies and delivered the documents to the following researchers for preliminary verification.
If the verification is passed, the next step is to enter the structure refinement and data preparation stage.
On this day, after a day's work, Chen Nian took a walk in Dongqi Park alone to rest and refresh his mind.
While drinking the coconut juice that the logistics department had specially brought for him from Hainan the night before, he opened the system panel and checked the recent harvest.
Since he mainly focused on technical output, he did not put much weight on knowledge absorption during this period, but even so, the number of source points was still growing at a stable rate.
In two weeks, a total of 1.76 source points were added. Adding the original stock, his number of source points came to 2.99.
While he was checking the panel, the number jumped up again, reaching 3.04.
It is estimated that some project has undergone technological fission and contributed source points to itself.
Now the growth rate of Yuandian is picking up again, and it is estimated that it will break through the 5-point mark before long.
So what should we choose as the next technology?
Regarding the Deep Blue 16 project, some source points must be reserved.
After all, what he analyzed this time was only the technology of the AGT110 itself, and the prerequisite infrastructure, materials, and equipment still needed to be solved one by one.
It's impossible to really pin all your hopes on the Motor Sich Factory.
Even if they have the equipment and materials, they cannot fully meet our needs. At most, they are just a foundation.
If you want to build a tall building, you have to do it yourself.
Electrolytic machining, directional solidification, electro-hydraulic 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 developed in advance. At least in terms of materials, there are basically no big problems.
Especially TBC.
For heavy-duty gas turbines, this thing is very important.
He finished the coconut juice in his hand and started walking towards his residence. The moment he entered the red zone, the researcher who had been waiting for a long time immediately came up to him.
"Gong Chen, you are back!"
Chen Nian looked up and saw that the person who came was the special interface person assigned to him by Dongqi Automobile, who was responsible for all technical and daily affairs during his time at Dongqi Automobile. His name was Xu Yuan.
"Uh, you're back, what's wrong?"
To be honest, Chen Nian is 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 have been placed inside, and it feels like "no one knows they are lychees".
But this time, Xu Yuan didn't seem to be polite to him.
"There is something wrong with the technical team, and I would like to trouble you to come over and take a look."
"What specific problem?"
Chen Nian's expression immediately became serious. He knew that at this time after dinner, if there was no real emergency, the general manager of Dongqi would not allow anyone to disturb him.
"It's about predicting the thermosolid properties of turbine blade flow. The technical team has looked at 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 thermosolid characteristics of turbine blade flow is actually simply the prediction of the working load of gas turbine turbine blades.
At high temperatures, continuously operating gas turbine turbine blades bear a variety of 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 research on the comprehensive properties of fluid, heat and solid is currently the most basic means of obtaining data.
If there is a problem with this prediction, the design characteristics of the turbine blades cannot be accurately realized in the subsequent R&D and manufacturing processes, which may result in shortened component life, reduced stability, and even the risk of collapse of the entire gas turbine system. .
"How exactly are they 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 previously, the technical team simulated the impact of three air film hole types: dustpan-shaped, conical and cylindrical on the local cooling efficiency downstream of the hole row, but the final data results were completely different from your conclusion. "
"completely different?"
Chen Nian repeated it subconsciously, feeling extremely confused.
He carefully recalled the data he had provided before, trying to find the key to the problem.
According to the model and results provided by the system, within the range of Reynolds number of 10,000 to 25,000 and blowing ratio of 0.3 to 2.0, the optimal 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 expanded hole is higher than that of the cylindrical hole.
In addition, the contraction-expansion hole can also expand the air film coverage area by forming coupled vortices, resulting in a 110% improvement in cooling efficiency.
Chen Nian had done preliminary calculations 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.
Could it be that the data given was wrong?
Or is there something wrong with the system?
possible.
After all, the system gives 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 turbine?
That’s not right. If that’s the case, can the model still be called a model?
Chen Nian felt increasingly puzzled, and he quickly said to Xu Yuan:
"Come on, let's go take a look. If there is any problem, we need to solve it as soon as possible!"
"Understood, we are all waiting for you, I will take you there now."
At work, Xu Yuan did not have the arrogant and conciliatory style of the agency. The two of them quickened their pace and walked towards the laboratory.
While walking, Chen Nian thought secretly in his heart:
Hope nothing goes wrong.
——
But even if something goes wrong, it doesn't matter.
It’s not like I’ve learned so many things in vain.
If it's really something the system can't handle, then I'll take care of it myself!
