Chapter 395 A new design method for turbofan 10 (page 12)

Half an hour later, accompanied by soft entrance music, the first China Aerospace Engine Industry Conference officially opened.

In the past, Chang Haonan, who could only sit in the back row during such meetings, was naturally invited to the middle position in the first row as the most important guest and meeting organizer.

Sitting with Liu Zhenxiang, who was also specially invited.

Originally, the conference affairs department planned to arrange for him to give the first report immediately after his speech, but Chang Haonan said that the content he prepared was too long and too formal, and it was best to put it in the finale.

This can also maintain the expectations of attendees to a certain extent.

He has read the reports prepared by several other people before. In terms of the current development level of China's aviation power field, they can be considered to be of a very high level. Many of the conclusions were only achieved after the 21st century in previous lives.

Although they are all breakthroughs in very specific directions, so they are not considered a leap forward, but in terms of research ideas and methods, they can definitely inspire researchers in other fields.

And if Chang Haonan throws out his heavy content first, then probably not many people will care about the following things——

You have to leave some opportunities for others.

Therefore, after briefly summarizing the achievements in the field of aerospace engines over the past year, Chang Haonan generously gave the first official opportunity to the academician Liu Zhenxiang next to him.

Although the latter is also a Taishan Beidou-level figure in the industry, the main content of his report is about the Chinese aerospace engine industry standards that are currently being formulated, especially the relevant standards in plateau environments of 3000 meters and above. Following several reports There is not much overlap in content.

"Due to China's special geographical and terrain conditions, a considerable number of airports in key directions are built on plateaus and high plateau areas. This is a situation that almost no other country has ever faced. Therefore, a plateau condition standard that meets the requirements of our national conditions is important for It will undoubtedly be of great significance to my country's national defense security and the flight safety of the civil aviation industry..."

"..."

As Liu Zhenxiang's report came to an end, Chang Haonan also lowered his head, preparing to sort out the key points he had just written down.

But at this moment, he suddenly heard his name.

"Finally, I would like to express my special thanks to Comrade Chang Haonan."

Chang Haonan raised his head almost subconsciously, and then found Liu Zhenxiang staring at him with a smile behind the podium.

"If he had not submitted a key technical document to his superiors at the critical moment of high-altitude bench testing of the turbojet 14 engine, I am afraid that the entire aviation industry standard content we see today would not have appeared. From this, A series of new projects and new models will undoubtedly no longer exist."

As soon as these words came out, the whole place was in an uproar.

The large-scale revision of the aviation-related clauses in the national military standards has been a matter of great turmoil since the second half of last year. It is also closely related to the projects of almost everyone here, so it is impossible for anyone to not know about it.

But all along, not many people know the specific details.

Everyone only knows that the whole thing started when the aero-engine quality acceptance standard GJB/Z64-94 was suddenly modified into a completely new GJB/Z64-97A.

This is definitely something everyone expects. After all, the original set of standards copied from the Americans are completely unsuitable and lack operability. Not to mention passing the test more than two years after its release, no one can even explain how the test should be carried out. .

Now it is replaced by a new standard that although the strictness is not the same, but it can even tell you which screws to turn and how many turns during the test, which is naturally very satisfying.

But before today, not many people knew that the core content of GJB/Z64-97A was almost completed by Chang Haonan alone.

After a few seconds, the entire venue finally came to its senses and began to give Chang Haonan thunderous applause.

Now that the situation has reached this point, the latter has no choice but to stand up, turn around and gesture slightly to the back.

However, Liu Zhenxiang seemed to have made a bad start.

The content of the report at this aviation industry conference is actually more or less related to Chang Haonan.

Now that even Academician Liu expresses his gratitude, do other people have a reason to mention it specifically?

So everyone has to say a sentence or a rainbow fart at the end of the report.

Chang Haonan had already read all the report content, so his original plan was to sneak out to rest after Liu Zhenxiang finished speaking, and then return to the venue when it was his turn.

As a result, after doing this, the eyes of the whole audience would focus on him every once in a while, and there was no chance at all.

Due to standard conversion, even if the old standard is not implemented at all, the conversion only involves paper content is a very complicated matter, so Liu Zhenxiang distributed a lot of less important content in the form of vertical topics to some people with sufficient confidentiality levels. Project Team.

Although the funding is not much, it is almost a life-saving straw for many people.

And many people here today have benefited from it.

It is no exaggeration to say that Chang Haonan can be regarded as half of their parents.

Therefore, even during lunch and breaks between meetings, waves of people came to the front to express their gratitude or admiration to Chang Haonan...

……

When the meeting process finally progressed to Chang Haonan taking the stage, he even felt a little relaxed.

The applause lasted longer than the previous times.

Chang Haonan stretched out his hands and pressed down, and then the whole place fell silent again.

"Comrades, what I want to talk about today is more formal."

Chang Haonan said as he clicked on the first page of his PPT and projected it on the screen:

"Full three-dimensional design and unsteady analysis method of the third-generation high-thrust turbofan engine"

The moment this title appeared, the entire venue fell silent.

What followed was the clatter of notebooks being opened almost in unison.

Everyone is in the industry, and everyone knows what the description "third-generation high-thrust turbofan engine" refers to.

You know, the successful finalization of a second-generation turbojet engine last year injected a huge amount of funds and vitality into the aviation power field that was unimaginable in the past.

Now this is obviously to transfer the Turbofan 10 from the pre-research stage to a real project.

If you can participate in it, whether it is an improvement in your abilities, resume or connections, it will be immeasurable.

Therefore, everyone immediately got into high spirits.

Seeing that everyone was ready, Chang Haonan officially began his report:

“The previous speakers today have introduced in great detail some of the most cutting-edge research in the field of aviation engines in our country. I am very happy to see that after the successful completion of the design and production of the turbojet 14, our aviation engine research has It did not stay where it was, but was pushed further to new heights by you..."
