A question sentence that stood out directly made Liang Zhuoping stunned for a moment.

Although he had just guessed that the aviation industry conference that Chang Haonan applied for would definitely be able to start, would it be too fast to make a decision?

But after thinking about it, he nodded quickly;

"Of course Linyu can, and I will start arranging the relevant preparations for the meeting after I go back."

Just kidding, the leader puts forward all his ideas and then asks for your opinion.

Can you still say that I disagree?

You don't agree, some people agree.

"In addition, Xiao Chang, now Director Huai's side is negotiating according to the strategy you put forward last time, and the progress is quite smooth, if the D436T1 engine can be introduced into China for production at the same time, it will also be a promotion for the development of the aviation power field, so the specific date of this meeting, I think I can wait a little."

After getting Liang Zhuoping's reply, Ding Gaoheng turned to Chang Haonan again and said:

"But don't worry, it won't drag on for long."

"Did it go so well?"

The strategy of killing three soldiers with two peaches also refers to the negotiation process of the introduction of high-speed rail in the previous life, but even Chang Haonan himself did not expect that the effect would be so immediate.

"Yes, according to the information fed back after Lao Huai's visit to Zaporozhye two days ago, the situation on Ermao's side is even worse than we expected before, so Ivchenko-Progress quickly chose to compromise in the face of the risk of completely losing the opportunity to cooperate and participate, and the two manufacturing plants in Ufa and Moscow also symbolically gave a small step, and there is no fundamental conflict between the two sides at present, only some details need to be determined."

Ding Gaoheng nodded and replied:

"In addition, part of the reason is that this engine is also very important for many of their models under development, such as Antonov's An-72, Beriev's Be-200 and Yakovlev's Yak-42M, so we hope to use the funds we provided when we introduced it to further improve."

In fact, after a series of huge stimuli from Huaxia's side, especially after learning that Huaxia and the European Aviation Agency had successfully signed an airworthiness mutual recognition agreement, Da Mao's thinking also quickly completed self-exculpation-

Many people realize that with such a development trend, some technologies that are still relatively valuable now may be overcome by others on their own in a few years, and the risk of continuing to sit on the ground is too great.

On the contrary, it is better to take advantage of the current leading edge to earn visible money in your hands as soon as possible, and then engage in product iteration.

Maybe it could last a little longer.

So in recent months, negotiations of a similar nature have become much smoother than before.

For Chang Haonan, the value of the D436T1 engine itself is secondary, and its D36 core machine is especially worth eating and continuing to develop.

The D18T used in the An-124, the D136 used in the Mi-26, and the D27 used in the An-70 are all derived from a series of classic aviation products from the Yvchenko Design Bureau.

If it can really be obtained, then its position in the future Huaxia Aviation power field will not be inferior to the core aircraft of the turbofan 10.

He's already thinking about how to incorporate it into his plans:

"It's really worth waiting, and in the future, we can even consider using our own technology to continue to feed back and upgrade, and its core engine has great potential, and we can continue to develop other types of thrust engines on this basis when conditions arise in the future."

This sentence is indeed heroic.

Prior to this, the only aero engine model that was independently improved and successfully mass-produced by Huaxia was the turbojet 7/turbojet 13 that was imitated from the R11F-300 and slightly upgraded all the way, which was used as aviation power for almost all the main domestic fighters.

But after all, it was only Soviet technology in the early 50s, and it was not difficult to make some small technological improvements after thirty or forty years.

The D436 is not a backward model even in the mid-90s, and in some performance it is even better than its Western counterpart.

Third, the rotor structure has never been touched by Huaxia before.

According to past experience, even if such a model is only to complete the localization, I am afraid it will take some twists and turns.

But since this was said by Chang Haonan......

Ding Gaoheng still secretly raised some expectations in his heart.

"Aviation power, in the past few decades, has been the most important lifeline restricting the development of our aviation industry, if Comrade Haonan can this time the turbofan 10, the thrust weight than the 8 level of the third generation to tackle the problem, our two types of domestic third-generation fighters will really have no worries."

Perhaps inspired by Chang Haonan's confidence, Liang Zhuoping next to him couldn't help but think of the situation after the new engine was finalized:

"Even if this is placed in the entire industrial history of China, it is a thing worthy of special mention."

Although he had not had much contact with Chang Haonan in the past and had not intuitively felt the other party's ability, a strong intuition still made him decide to set up a special preparatory team after he returned, in addition to being responsible for the logistics and administrative work related to the conference, and more importantly, keeping some archives, pictures and video records.

Liang Zhuoping has a hunch that these things may become very important historical materials in the future.

However, he still completely underestimated Chang Haonan's goal:

"It's not just the power of third-generation fighters."

The latter shook his head slightly:

"This time, let Director Ding come forward and concentrate the strength of the whole country, and my further idea is to take this opportunity to establish a systematic development plan for the aero engine industry."

"In the past, our aviation development research, even including the turbojet 14 that has just completed the finalization, regardless of performance, has a strong isolation in technology, and the technical connection between different types of aviation development is very weak, and almost every project has to build wheels from scratch, and the efficiency is naturally not high."

"In the past, we had few main engine models in our hands, so it was still bearable, but in the future, with the increase of our aviation product types, there will be higher requirements for the diversity of aviation power."

Speaking of this, Chang Haonan stretched out his hand and began to count items one by one:

"Even if the situation on the civil aviation side is not considered for the time being, only military weapons and equipment are counted, then the two third-generation fighters need small bypass ratio turbofan engines with afterburner thrust of 12 to 13 tons, bombers and transport aircraft need large bypass ratio turbofan engines with thrust of 13-15 tons, new trainers need medium-sized turbofans with afterburner thrust of 7-8 tons, large UAVs need models without afterburner with thrust of 4-5 tons, and cruise missiles need small turbojets or turbofans with thrust of less than one ton......"

Chang Haonan's inventory made Liang Zhuoping a little unbearable.

Many of these models, not to mention the project, do not even have an idea at the moment.

But the latter did not open his mouth to refute -

There are not so many models, is it because he doesn't want to?

How can it be?

I didn't know that I had this ability in the past, right?

What person in charge of the aviation industry doesn't want to have what he wants?

So although Liang Zhuoping was still a little complaining in his heart at the beginning, he was attracted by the bright future depicted by Chang Haonan in the end.

"So my idea is to establish a core model spectrum sequence that includes 4-6 levels, conversion flow rates from 5kg/s to 25kg/s, and cycle power from 1MW to 20MW, which is enough to derive various engine models with thrust ranging from 200 kg to 25 tons, and then consider the different schemes of single-engine, twin-engine and four-engine, which can fully meet the power requirements of the vast majority of aircraft in the next 20-30 years."

"With such a core aircraft system, when a new aviation engine is needed, there is no need to start from scratch as in the past, but only need to make small modifications on the basis of existing models, and the time and capital costs consumed will be greatly reduced!"

Ding Gaoheng and Liang Zhuoping were both silent.

The amount of information is relatively large and takes some time to digest.

This kind of thing, the low EQ is called painting cakes, and the high EQ is called depicting a grand blueprint.

It mainly depends on who the specific person is.

Specific to Chang Haonan, it is naturally inclined to the latter situation more.

"I'm afraid this process still has to be carried out in stages, right?"

After a long time, Liang Zhuoping asked tentatively.

"Of course, the current plan is to first get the core machine with 25kg/s flow rate and 20MW power level, in addition to the turbofan 10, it can also derive a high bypass ratio model used in large aircraft to solve our most urgent needs."

Chang Haonan is also a down-to-earth person after all.

If five or six models were to go hand in hand, it would be impossible for him to bear it.
