Chapter 418 The first compressor research center in the country
As the saying goes, small meetings are held in big meetings, and big meetings are held in small meetings.
After that small meeting of ten people, the general technical direction of the turbofan 10 was basically determined.
In this way, most of the issues that really need to be left to the meeting of all key members are some organizational issues.
However, despite having made sufficient mental preparations before, the difficulty and complexity of actually taking charge of an entire project far exceeded Chang Haonan's initial imagination.
Even without encountering any obvious internal resistance, it still took him almost half a month to finally allocate all the core research and development tasks involved in the Turbofan 10 project.
The deadline was fully doubled from the original plan.
Of course, for Chinese aerospace researchers, things like doubling the delay were basically routine in the past...
So it is not a big problem.
Fortunately, everything is difficult at the beginning, but the subsequent work is much easier to straighten out, and the entire project team is gradually getting on the right track.
For Chang Haonan during this period, in addition to the overall design of the header turbofan 10, the first thing he had to complete was to build a specialized small high-speed adsorption compressor test bench.
TORCHMultiphysics can indeed perform numerical calculations and simulations of design solutions with a very high degree of fidelity, but this is for the design process, and the content involved must also have existing theories in the past or at least Only basic engineering skills are required.
It is an international initiative to apply the boundary layer suction principle to the design of compressor blades. Therefore, Chang Haonan not only has to complete the turbofan 10 project, but also has to improve the theoretical content in this area. , let those who come after you understand why.
On the other hand, even if the entire design process can be completed on a computer in the future, the finished product will always have to be tested on a real machine before it can be finalized.
This is not only a national standard, but also the bottom line of aviation safety.
If you just rely on "I Xunsi" to design, sooner or later there will be problems.
However, this test bed equipment cannot be placed in Shengjing.
Because the data calculations it generates require extremely high computing power to complete the analysis, and neither the 606 Institute nor the 601 Institute currently has a supercomputer on hand that meets the requirements.
So in the end I could only arrange it to be at Beijing Hang University.
At this moment, the happiest person is naturally Tang Lintian.
When he heard Chang Haonan, who was rushing back to the capital after a long journey, talking about this matter, he almost reflexively jumped up from his chair and strode to the latter.
If Zhu Yadan hadn't been standing next to him in an imposing posture, Chang Haonan would have no doubt that the other party would hug him and kiss him a few times.
"Comrade Haonan, tell me, what kind of support do you need from the school? Even if the whole school faculty and staff dig into their own pockets to advance the money, we will definitely meet your requirements!"
A university wants to In addition to high-level researchers and sufficient funding, there is another item that is easily overlooked, which is some irreplaceable experimental equipment.
Especially for the engineering field, these equipments often require large investments, long cycles, and relatively narrow applicable fields. Once a set is built in a country, or at least in a region, it is difficult to make the decision to repeat it. Construction, so all research groups engaged in related research within a certain range will be physically concentrated around this only single seedling.
Institutions that own this kind of equipment can naturally gain huge benefits from it. At least some of the research results must be shared, and a name must be added to the signature.
Over time, it has formed a leading position in this discipline or direction.
Of course, there are other reasons why Tang Lintian, who has always been relatively stable, lost his temper like this.
Prior to this, Beijing Hang University had suffered losses in this regard in the construction of the school-level wind tunnel laboratory, getting up early but rushing to work late——
Although the predecessor of Beijing Hang University, Beijing Aviation College, was established in 1952, it soon owned four then-very advanced scaled-down wind tunnels D1-D4 through moving in and building it by itself. Among them, D4 wind tunnel was fully involved in the process. The development work of my country's first light passenger aircraft "Jingcheng No. 1".
However, in the following decades, Jinghang University did not build newer wind tunnel facilities, and was eventually overtaken by Northwestern Polytechnical University in this regard.
One step at a time, one step at a time. Although Beijing Airlines later tried to catch up with its competitors in this regard, the situation did not improve much until the 1990s.
Mainly because in this year and age, there are not many research projects in China that can use wind tunnels. For large national projects, base 29 in Fucheng can be used for testing, so Beijing Airlines flew there. The application for the construction of a new wind tunnel has never been approved, and we can only patch up the D4 wind tunnel that has been used for 40 years.
The test bed plan brought by Chang Haonan from Shengjing can completely serve as a new track for Beijing Hang University.
"Well...it's not necessary to be so exaggerated as to sell iron. This test bench is part of the turbofan 10 project. It does not require funding from the school. All I need is a place. It would be better if the area is larger." Chang Hao Nan looked at Tang Lintian who was a little too enthusiastic and couldn't help but take a half step back.
"Hey, how can that be done? The school must support Comrade Haonan in your work."
Tang Lintian directly stretched out his hands and held Chang Haonan's hand:
"I think it's better to take this opportunity to establish a compressor research center. You don't have to worry about funding. Except for the funding related to Project 10, the school will fill the remaining vacancies for you!"
Chang Haonan was a little surprised by the other party's sudden generosity.
"Dean Tang, isn't this a bit too aggressive..."
After all, in his impression, his school was not so tight in the late 1990s, at least it was not so wealthy.
“In any case, the school could have so much surplus funds in the first half of this year because it borrowed your money and used these funds to support your work, which is what it should be...”
Tang Lintian quickly explained, fearing that Chang Haonan would not want the money.
For Beijing Airlines, no matter what new research field they want to engage in, passing the approval is the most difficult part. But now that Chang Haonan has a sword like the Taihang project in his hand, what other approval can make life difficult for?
As for the money, it is even more trivial -
When the research team is awarded a horizontal project, the funds it receives will basically be plucked once by the school.
The ratio varies from one quarter to one half.
Of course, the funds for people like Du Yishan or Chang Haonan must be paid in full.
But in the past year, under the leadership of the latter, other research groups in the school have also received many more projects than in previous years.
There are not only vertical topics from higher-level units, but also horizontal topics provided by many state-owned enterprises and even private enterprises.
Accordingly, the school reluctantly made a lot of money from it.
Sponsoring a research center is no longer unthinkable.
"Then...let's build three of these compressor test benches at the same time."
Since the other party's hospitality was hard to refuse, Chang Haonan was no longer polite.
"Okay."
Tang Lintian nodded.
“The design single-stage pressure ratios are 1.4, 1.6 and 2.4 respectively, corresponding to the upper speed limit of the blade tip of 150m/s, 300m/s and 600m/s respectively.”
“Listen to you "
Tang Lintian nodded again.
"In addition, I also need a large test bed with non-contact scanning temperature measurement equipment, as well as corresponding fuel pipelines and ignition equipment. The working temperature must reach at least 1600°C."
This is obviously the same as The compressor of the cold end component has nothing to do with it, but Chang Haonan’s preparation for subsequent turbine research.
The extent of this extravagance made Zhu Yadan, who could not understand the conversation between the two, a little worried.
However, Tang Lintian glanced at Chang Haonan and after half a second of hesitation, he gritted his teeth:
"That's okay."
"Then it's a deal!"
Chang Haonan stretched out his other hand with satisfaction:
"But my energy is really limited now. Please let my teacher be in charge of this experimental center."
“Deal.”
The four hands of the two people were tightly held together.
