Chapter 1077 The Goal Is Global Airworthiness

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

China, Haojing.

Although it is almost nightfall, the headquarters building of Haofa Group is still brightly lit.

After finalizing several large cooperation orders with Europe, Haofa, or the entire aerospace power group, has finally completed all preparations before the establishment of the Turbofan 20 project.

And today is the day when project approval officially begins——

The complete project establishment work requires the examination of a large number of technical and feasibility study documents. It is actually a quite boring task and cannot be completed in three or two days.

Therefore, what is happening now is just a launching ceremony, with Chang Haonan briefly introducing the project situation and the overall technical plan.

Of course, the Turbofan 20 is the model that Chang Haonan personally took charge of after two years.

Therefore, it is not difficult to predict that the specifications will definitely be full.

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

But foresight is foresight.

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

Not to mention researchers related to aerodynamics, engineering control, and materials science.

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

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

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

But coming here to show up at this juncture itself represents the attention from the top.

Or 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 Turbofan 20 are deliberately weakened.

But this is also a real hardship for the comrades in charge of arranging 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...

In the list, Chang Haonan also saw a name that was completely unexpected.

His mentor, Du Yishan.

Although academicians, especially senior academicians, mostly retire unless they have physical reasons.

But maybe it's because he did bring out a more up-to-date close disciple. In short, Du Yishan did stay relatively reclusive after leaving the front line.

I rarely participate in such official level activities anymore.

Even Chang Haonan, Liu Hongbo and others' requests to visit were often rejected unless it was a holiday.

Now that he appears in Haojing, he may have been specially invited by his superiors.

"teacher."

After greeting the senior leaders, Chang Haonan looked around at the door for a while before waiting for Du Yishan, who was surrounded by several staff members.

Then he quickly stepped forward to help the other person sit down.

But the latter raised his hand and refused:

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

As he spoke, he even sped up his pace.

In fact, what Du Yishan said was a bit modest -

After retiring, he looked much younger than before.

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

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

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

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

While placing the cup with tea in front of Du Yishan, he said with some emotion:

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

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

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

"I guess the higher-ups really can't think of anyone else who can review your project... When the Turbofan 10 project was approved, your boy made it a live lecture."

"Before setting off from the capital this time, Lao Ding also told me that he wanted to know what other tricks the turbofan 20 can do..."

Suddenly hearing Ding Gaoheng's name in this context made Chang Haonan a little uncomfortable.

But after thinking about it, it makes sense.

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

Even though he is an academician-level expert, he can still find reasons to come if he really wants to participate.

But this is after all a critical and sensitive stage of organizational reorganization, and the Turbofan 20 is the first key project handled by the new unit of the Industrial and Construction Commission after it was established.

If he, the "old leader" who had just resigned, appeared at the same time as Li Zhongyi, there is no guarantee that he would not be overthought by interested people.

However, Chang Haonan still gave up:

"You should know later..."

…

At seven o'clock that night, the launching ceremony officially began.

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

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

"Everyone, the turbofan 10 has been put into mass production for more than a year since it completed the production and finalization evaluation at the beginning of last year. Including the previous small batch trial production, a total of 127 units have been put into use, with a safe flight time of more than 100,000 hours, without causing any The third-class or above flight accident has received unanimous praise from Party A and customers..."

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

“In addition, it is worth mentioning that not long ago, we also helped to identify the cause of an accident related to the prospects of the Trent 900 project. Not only were we exposed to many cutting-edge design ideas in the process, but we also further improved our country’s international reputation. The right to speak in the aviation manufacturing industry.”

"..."

These words are not only a background introduction, but also a summary of the work of the Aerospace Power Group since its establishment.

Although everyone here is aware of and even participated in everything.

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

Unknowingly, Huaxia has become equal to international aviation giants like Rolls-Royce in some fields.

So, when he finished speaking a long paragraph and paused to take a sip of water, the gasps of everyone could be heard quietly in the huge conference room.

It wasn't until Chang Haonan opened the lid of the cup and there was a clicking sound that the first person reacted and started applauding.

Then, it was like a switch was turned on.

Thunderous applause resounded throughout the entire venue in an instant.

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

"In this context, we believe that we are fully qualified to rely on the relatively mature core engine of the Turbofan 10 to develop a large bypass ratio turbofan engine with a thrust between 12-14 tons and mainly used for passenger aircraft and transport aircraft. The Group The level is temporarily named AE1500..."

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

Mainly for rigor.

In fact, names such as turbofan XX and turboshaft XX should be given to the equipment by the users, that is, the troops.

However, because China's aviation manufacturing industry has been specialized in aviation for a long time, these names have gradually been accepted by manufacturers.

Later, for models such as Turbofan 10 and Turbojet 14, even at the beginning of the project, the names were decided for the users.

Neither side felt there was any problem.

But with the development of the industry, it has become clear that China Aviation Development’s users are no longer just the military.

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

As for the Turbofan 20, it should be formally determined after the aviation force passes the acceptance test.

Of course, in today's meeting, these parts can only be regarded as details.

Because when Chang Haonan announced the name of AE1500, the goal he set for this model was also projected on the curtain in front.

Suddenly there was a burst of exclamation in the scene.

The top one is naturally thrust.

The sea level thrust of the basic model is 13500kgf, which can be adjusted from 11500kgf to 14500kgf according to different sub-models.

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

However, the focus of large bypass ratio turbofans is not originally here.

What really exceeded the expectations of all the big guys was another form further down.

"Considering the difficulty of research and development, testing, mass production, and gaining market recognition, AE1500 should benchmark against similar products of the 2010s in advance to ensure that it does 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..."

"..."

What is more surprising than the data itself is 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, factors at the international aviation policy level must also be taken into consideration."

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

When he said this, Du Yishan in the audience suddenly guessed his disciple's goal this time——

Obtain global airworthiness certification!
