The Military-industrial Scientific Research System of the Academic Master Chapter 989

Chapter 989 So terrifying.jpg

After Jacky Wen finished speaking on his last page of PPT, he turned around, stood on the podium and looked around.

The following technical personnel from the Navy and other fields were either lowering their heads in thought, nodding their heads, or writing furiously...

In short, they all showed a very serious attitude.

Obviously, his introduction this time had a good effect.

Seeing this scene, Jacky Wen couldn't help but breathe a sigh of relief.

He put his hands behind his back, and he felt like he was looking down on the world.

Although the foundation of GT25000 is indeed not as good as QC300, this is mainly reflected in its design as an industrial gas turbine.

Whether it is power generation or pipeline power, there is no need to pursue extreme compactness.

After switching to marine power, this aspect became a shortcoming that was difficult to optimize.

However, Jacky Wen felt that, regardless of future matters, if he ate the power system of the 052 series follow-up ship today, the problem should not be big.

On the one hand, the index performance of GT25000 is not bad, and it also has considerable upgrade potential, which is completely sufficient for the 052 series.

On the other hand, it is also more important.

He has seen the gas turbine designed for the Type 054 frigate based on the 606 turbojet 14.

From a technical point of view, it is indeed close to impeccable.

But it can be seen that the other party is still designing gas turbines with the same ideas as designing aviation engines.

For example, in order to improve fuel economy under normal conditions, a relatively low design point speed has to be selected, resulting in a certain impact on the maximum power and corresponding efficiency of the speed.

It is precisely for this reason that today he specifically mentioned the receiver adaptive processing technology that can broaden the working range.

After all, even with a diesel-fuel alternating power system, the gas turbine cannot always operate at high speed.

Cruise diesel engines generally can only provide a speed of just over 10 knots, and if you want to go faster, you have to start the gas turbine, whether it is 20 knots or 30 knots.

With this thought in mind, Jacky Wen slowly walked off the stage amid a burst of warm applause.

Even in the process of returning to his seat, he even made a slight detour and passed by Yan Zhongcheng.

It turned out that although the other party was also lowering his head to remember something just now, the content was different from what he imagined -

Although it was just a short walk, Jacky Wen still managed to catch a piece of content with his excellent dynamic vision.

"The casing processing has little impact on the core part of the whole machine, and the effect is poor compared to xxxx technology..."

"Is it possible to consider combining receiver adaption and xxxx technology?"

"hiss…"

Jacky Wen held his breath almost subconsciously.

Yan Zhongcheng's handwriting is very fast and the time is short, so many of the handwriting can only be half recognized and half guessed.

But everyone is engaged in gas turbines, so most of the content is not difficult to guess.

Only the xxxx technology, I didn't see what it was at all.

Jacky Wen spent a few seconds picking out all the proper nouns in his mind and comparing them, but he couldn't find any matching ones.

At this moment, he who was so confident just now finally realized that something was wrong.

Regardless of what xxxx is specifically, it seems that the purpose of the other person taking notes is not, or at least, not just to learn ideas as I thought before.

It's more like...

Prepare countermeasures.

This countermeasure was not even thought of on the spur of the moment.

But it was prepared in advance.

Yan Zhongcheng wouldn't just make up a technical term to deceive everyone, right?

Just like that, when Jacky Wen sat back down in his seat, a thin layer of sweat even appeared on his forehead.

He didn't even hear an engineer from the Shanghai 711 Institute asking technical questions.

He didn't react until the other party called him again.

Institute 711 is responsible for the research and development of marine diesel engines.

It's just that it's not the cruise main engine, but the power generation auxiliary engine.

"Mr. Wen."

The other party looked over and said:

"Is it possible that the technology you developed can be used in the intake rectification of internal combustion engines?"

Jacky Wen had no choice but to turn his attention away from Yan Zhongcheng for a moment:

"Of course it's no problem in theory, but I remember that internal combustion engines don't rely on airflow characteristics like gas turbines. Just ensure enough air intake..."

"Of course this is usually the case, but if it is a diesel engine equipped with a sequential supercharging system, in some special cases it is still necessary to make some adjustments to the air flow, but it does not need to be as precise as your steam turbine..."

Just as the two were discussing the issue, Yan Zhongcheng was already standing on the podium.

The conference room, which had been slightly noisy before, became quiet again.

"I just listened to Jacky Wen's introduction, which was very beneficial to me..."

After a brief opening remarks, Yan Zhongcheng directly praised Jacky Wen.

However, from the latter's point of view, this flattery seems to have a bit of yin and yang, and even means to take pleasure in others' misfortune.

This made him frown.

The inner uneasiness became more and more intense.

"Compared to the GT25000, which is very mature and has even been installed and tested on ships, our QC300 should be considered a new face to our colleagues in charge of power system research and development." Yan Zhongcheng said with a slight smile in his tone at the beginning. But at this point, the conversation immediately changed:

"However, judging from the performance indicators alone, comrades in the Navy may feel a bit familiar..."

He said and turned the PPT to the second page.

Upstairs is a quite detailed performance data table.

The content is naturally what Chang Haonan said before.

QC300 has not officially entered the research and development stage at this time, so it is naturally impossible to have such detailed content as the power-speed curve.

However, as far as the current situation is concerned, it is enough.

Almost at the same time as the form was released, there were several bursts of exclamations in the venue.

Not because of basic numbers like power and efficiency—

Although these data are equally dazzling, Chang Haonan had already drawn the pie when the Aviation Power Group was established.

It's a part that everyone has been mentally prepared for.

The key is the features of this model.

Size, weight, box-packed design, and some modular ideas.

Although even a layman can tell at a glance that the QC300 and core machine are structurally very different from the TF39 and have no technical connection.

But for installation, use and maintenance, the shadow of LM2500 can indeed be seen.

This is also the advice Chang Haonan gave a few days ago -

For the Chinese Navy, the LM2500 is the undisputed white moonlight as a ship power.

If the acquisition channels were not locked, there is a high probability that there would be no GT25000 at all.

Although the QC300 is not the LM2500, it can benchmark in all aspects and even surpass the newly installed LM2500+ in key indicators.

Even from an emotional point of view, it has enough lethality.

After deliberately pausing for a while, Yan Zhongcheng continued to enlarge his moves:

"Every comrade should be aware that the turbofan 10 designed by the general manager of our office has been installed on the J-10A and J-11B models and has officially passed the production finalization at the beginning of the year. Calculated from the establishment of the project, it only cost a lot of money. to five years, so in fact, there is no need to worry too much about the development cycle of QC300..."

"Currently, the first two Type 052C destroyers are close to being launched, but as far as I know, there is no clear plan for the construction of follow-up ships. Judging from the timetable, QC300 can fully catch up with the progress of follow-up ships and even follow-up models..."

For the navy, this passage is absolutely lethal -

The speed at which the Chinese aviation equipment has been introduced over the years has been noticed by everyone.

It can even be said that the reason why the Navy has the idea of continuing to improve the 052C is largely influenced by this...

Or rather stimulated by it.

Now that Yan Zhongcheng has spoken out directly, he has naturally gained a lot of recognition.

As for some of the Spring and Autumn writing style in this paragraph, such as "Turbofan 10 is responsible for the arrest of 606" and other details, no one cares about it.

Jacky Wen sat in the audience and adjusted his posture awkwardly.

He knew that if he only judged from the current situation, then the opponent could only have some advantages on the scene at most.

Just by mobilizing emotions and playing emotional cards, you can win for a while but not for the rest of your life.

After all, when making the final selection, everyone has to come up with detailed technical solutions.

But the words Yan Zhongcheng just wrote in his notebook made him unable to let go.

Thinking of this, Jacky Wen moved his eyes away from the curtain in front and turned to Yan Zhongcheng's seat just now.

The notebook was quietly placed on the small table next to it.

At the same time, Yan Zhongcheng's introduction also happened to come to this part.

"In fact, after our QC130 was finalized, we also learned a lot of experience and lessons from it..."

He certainly couldn't say that he had just asked Chang Haonan for temporary help two days ago, so he had to push the source of this technology's ideas to the reflection on QC130.

However, this explanation is almost seamless, and it is impossible for someone who does not know the inside story to find anything wrong.

"Including what Mr. Wen just mentioned, naval gas turbines need to work at a speed far lower than the design point for a long time, so special attention needs to be paid to considering the actual performance under low operating conditions..."

Hearing this, Jacky Wen's heart tightened suddenly.

He knew the point was coming.

“In order to fundamentally solve this problem, we plan to use multi-stage adjustable stator vane matching technology on the high-pressure compressor of the QC300 to ensure its stability and high performance under all operating conditions. The basic principle is to adjust the speed according to different speeds. Different stator blade attack angles and blade tip clearances are selected for the intake flow characteristics of the lower compressor..."

With a "click-" sound.

The pen in Jacky Wen's hand fell off.

He has now thought that the "xxxx" that he couldn't understand before was actually the four words "adjustable static leaf".

Obviously, I still greatly overestimated the negative impact that lack of experience would have on the other party.

In other words, the other party's ability to self-correct is greatly underestimated.

Regarding the imperfections of QC130, others have already begun to make adjustments before the trial of 054 has begun.

It can almost be said that the celebration banquet and the reflection and summary meeting were held together.

Such efficiency, and such execution...

A sense of crisis suddenly came to my mind.

"What a terrible opponent..."

He bent down and picked up the pen, thinking silently at the same time.
