The military-industrial scientific research system of the academic master.

Almost at the same time, Brown and McKemick were worrying about the F136 engine and even the entire natural variable cycle technology route.

China, Haojing.

Although it was almost nightfall, the headquarters building of Gaofa Group was still brightly lit.

After finalizing several large cooperation contracts with Europe, Gaofa, or the entire Aviation Power Group, has finally completed all the preparatory work before the launch of the WS-20 project.

Today is the day when the project approval officially begins——

The complete project establishment work requires checking a large number of technical and feasibility study documents, which is actually a very boring job and cannot be completed in a few days.

Therefore, what is going on now is just a launching ceremony, where Chang Haonan will briefly introduce the project situation and the overall technical plan.

Of course, the WS-20 is the model that Chang Haonan personally took charge of two years later.

Therefore, it is not difficult to foresee that the specifications must be maximized.

At least it will be much higher than the QC300 from a year ago.

But foresight is foresight.

When Chang Haonan actually saw the list of experts and leaders attending today, he was still a little surprised.

Needless to say, researchers in aerodynamics, engineering control and materials science.

At the level of the Industrial and Construction Committee, Li Zhongyi, who had just taken office, attended the meeting in person.

In addition, higher-level leaders in charge of the development of high-tech industries were also present.

Although the other party said that he would only listen and not express any opinions, he asked Chang Haonan and others not to feel too much pressure.

But the fact that he showed up specifically at this critical juncture itself represents attention from the top.

Or rather support.

Correspondingly, the General Armament Department, which had more dealings with Chang Haonan in the past, only sent a delegation of average level and size to participate this time.

It is not difficult to see that the military attributes of the WS-20 are intentionally weakened.

But this also really made things difficult for the comrades at Gaofa who were responsible for arranging the conference affairs.

When Chang Haonan checked the final plan the day before, he found that even several academicians were not assigned a seat next to the conference table...

And on the list, Chang Haonan also saw a completely unexpected name.

His mentor, Du Yishan.

Although academicians, especially senior ones, usually retire but do not stop working unless due to health reasons.

But perhaps it was because he did bring up a more promising disciple. In any case, Du Yishan did live a secluded life after leaving the front line.

I rarely participate in such official activities anymore.

Even Chang Haonan, Liu Hongbo and others’ requests to visit were often rejected except during festivals.

Now that he appears in Gaojing, he must have been specially invited by his superiors.

"teacher."

After welcoming the senior leader, Chang Haonan looked around at the door for a long time before waiting for Du Yishan who was surrounded by several staff members.

So he quickly stepped forward and prepared to help the other person to sit down.

But the latter raised his hand and refused:

"Okay, okay, I'm not too old to walk..."

As he spoke, he even quickened his pace.

In fact, Du Yishan was a little modest in what he said.

After retirement, he looks a lot younger than before.

I can only say that even at the level of an academician, the work is indeed quite torturous...

After exchanging pleasantries with the acquaintances present, Du Yishan finally sat down in the seat assigned to him.

Chang Haonan was also able to take a break from his busy schedule and relax for a while under the pretext of "accompanying the teacher".

"Teacher, to be honest, I didn't expect you to come out in person."

As he placed the cup of tea in front of Du Yishan, he said with some emotion:

“Although it has only been four years since graduation, it feels like I haven’t seen you in a venue like this for a long time.”

"It's not really an appearance... You should have seen the list. I'm not actually on the project review team. I'm just here as an invited expert. I shouldn't be sitting in such a front position..."

Du Yishan drank a sip of water slowly, and then said in a half-joking tone:

"I guess the higher-ups can't think of anyone else who can review your project... When the WS-10 project was launched, you turned it into a live lecture."

"Before we set off from Beijing this time, Lao Ding told me that he wanted to know what else the WS-20 could do..."

Chang Haonan was a little uncomfortable hearing Ding Gaoheng's name suddenly in this context.

But after thinking about it, it makes sense.

After handing over the director position to Li Zhongyi, Ding Gaoheng took a sinecure and waited for retirement in two years.

Although as an expert at the academician level, I can find reasons to participate if I really want to.

But this is, after all, a critical and sensitive stage in the organizational restructuring, and the WS-20 is the first key project handled by the new unit of the Industrial and Construction Commission after its establishment.

If he, the "old leader" who just stepped down, appears at the same time as Li Zhongyi, it is hard to guarantee that he will not be suspected by some people.

However, Chang Haonan still kept it a secret:

"You will know it soon..."

……

The launch ceremony officially began at seven o'clock that evening.

With Chang Haonan's current status in the underworld, there is no need for him to be overly polite.

Therefore, he only gave a brief welcome speech and then quickly got to the point:

"Everyone, since the completion of production finalization and appraisal at the beginning of last year, the WS-10 has been put into mass production for more than a year. Including the previous small-scale trial production, a total of 127 units have been put into use, with a safe flight time of more than 10 hours, without causing any third-level or higher flight accidents, and has received unanimous praise from Party A and customers..."

"At the same time, in the past two years, our group has also cooperated with foreign companies to successfully develop the medium bypass ratio SeA650 turbofan engine, which has been equipped on the Falcon 8Z business jet for test flights. We have also undertaken part of the production business of Rolls-Royce's Trent 900 engine turbine components and accessories, and have accumulated certain experience in civil engines..."

"In addition, it is worth mentioning that not long ago, we also helped to identify the cause of an accident related to the future of the Trent 900 project. In this process, we not only came into contact with many cutting-edge design ideas, but also further enhanced my country's voice in the international aviation manufacturing industry."

"..."

These words are both a background introduction and a summary of the work of Aviation Power Group since its establishment.

Although everyone here knows about each of these events and has even participated in them.

But when these achievements were summarized by Chang Haonan and listed together on the PPT, it still brought an immeasurable shock -

Unknowingly, China has been able to stand on equal footing with international aviation giants such as Rolls-Royce in some areas.

So much so that when he finished a long speech and paused to drink some water, one could actually hear the quiet gasps of people in the huge conference room.

It was not until Chang Haonan lifted the lid of the cup, making a crackling sound, that the first person reacted and started applauding.

Then, it was as if a switch was turned on.

Thunderous applause filled the entire venue in an instant.

In the end, Chang Haonan had to raise his hand and press down to cool down the atmosphere in the entire venue:

"Against this background, we believe that we are fully qualified to develop a high-bypass turbofan engine with a thrust of 10-12 tons, mainly for passenger aircraft and transport aircraft, based on the relatively mature core engine of the WS-14. The engine is temporarily named AE1500 at the group level..."

Here, he specifically used the name he had discussed with Lan Xinzhi before.

Mainly for the sake of rigor.

In fact, names like turbofan XX and turboshaft XX should be assigned to the equipment by users, that is, the troops.

However, because China's aviation manufacturing industry has been dedicated to serving the air force for a long time, these names have gradually been accepted by manufacturers.

Later, models like WS-10 and WP-14 had their names decided on behalf of users even at the beginning of the project.

Neither side thought there was any problem.

But with the development of the industry, it is clear that China Aerospace Engine's users are no longer just the military.

Then when the project is established, there should also be a corresponding commercial model name assigned by the manufacturer.

As for the WS-20, it should be officially confirmed after the air force passes the acceptance.

Of course, in today's meeting, these parts are just minor details.

Because when Chang Haonan announced the name of AE1500, the goals he set for this model were also projected on the screen in front.

This immediately caused a burst of exclamations at the scene.

At the top of the list is naturally thrust.

The basic model has a sea level thrust of 13500kgf, and can be adjusted between 11500kgf and 14500kgf depending on the sub-model.

For the target installation object, it is considered to be a satisfactory level.

However, the focus of the high bypass ratio turbofan is not here.

What really surprised all the big guys was the other table below.

“Considering the difficulty of R&D, testing, mass production, and gaining market recognition, the AE1500 should benchmark similar products from the 2010s in advance to ensure that it will not fall behind in future competition.”

"Therefore, compared with the current benchmark model CFM56-7B engine, the AE1500 plans to reduce fuel consumption during cruising by 10%, reduce noise by 6dB, and reduce carbon dioxide and nitrogen oxide emissions by 25% and 40% respectively..."

"..."

Compared to these data themselves, what is more surprising is actually the focus of this model.

As if seeing everyone's confusion, Chang Haonan explained:

"As a model for the commercial market, in addition to the hard indicators we traditionally focus on, we must also consider factors at the international aviation policy level."

"Since the end of the last century, Europe and the United States have gradually tightened regulations on aircraft emissions. On the one hand, this is of course for environmental protection, but on the other hand, it is also setting additional obstacles for latecomers like us..."

When he said this, Du Yishan in the audience suddenly guessed the goal of his disciple this time -

Obtained global airworthiness certification!
