Chapter 378 The Road to High-Performance Aviation Engines!

Liang Zhuoping was stunned for a moment by a question that stood out.

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

But thinking about it, he quickly nodded;

"Of course Linyu can. I will start arranging the relevant preparations for the meeting after I return."

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

Can you still say that I disagree?

You may not agree, but some people agree.

"In addition, Xiao Chang, Director Huai is currently negotiating according to the strategy you proposed last time, and the progress is quite smooth. If the D436T1 engine can be introduced into our country for production simultaneously, it will also be a boost to the development of the aviation power field. , so I think we can wait a little bit for the specific date of this meeting.”

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

"But don't worry, it won't take long."

"Is it so smooth?"

The strategy of killing three people with two peaches was also based on the negotiation process for 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 feedback from Lao Huai after his visit to Zaporozhye two days ago, the situation in Ermao is worse than we previously expected, so Ivchenko-Progress Company is facing a completely The risk of losing the opportunity for cooperation and participation quickly led to a compromise, and later the two manufacturing plants in Ufa and Moscow also made a small symbolic concession. At present, there is no fundamental conflict between the two parties, and 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. We need it, so we hope to use the funds provided when we introduced it to further improve it.”

In fact, after receiving a series of huge stimulations from China, especially after learning that China and the European Aviation Administration had successfully signed an airworthiness mutual recognition agreement, Da Mao's thinking quickly completed his self-exculpation——

Many people realize that, judging from this development trend, some technologies that are still relatively valuable now may be conquered by others on their own in a few years. The risk of continuing to raise prices is too high.

On the contrary, it is better to take advantage of the current leading advantage, earn visible money as soon as possible, and then start product iterations.

You might be able to hold on for longer.

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

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

A series of classic aviation products from the Ivchenko Design Bureau, such as the D18T used by the An-124, the D136 used by the Mi-26, and the D27 used by the An-70, are all derived from this.

If it can be obtained, its status in China's aviation power field will not be inferior to that of the core turbofan 10 aircraft in the future.

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

"It is indeed worth waiting. In the future, we can even consider using our own technology to continue to support upgrades, and its core engine has great potential. In the future, if conditions permit, we can continue to develop other types of thrust engines on this basis."

This sentence is truly heroic.

Prior to this, the only aircraft engine model that was independently improved by China and successfully achieved mass production was the Turbojet 7/ Turbojet 13, which was copied from the R11F-300 and slightly upgraded along the way. It is used in almost all of the current The aviation power of domestically produced main fighter aircraft.

But in the final analysis, it was just Soviet technology in the early 1950s. It would not be difficult to make some minor technological improvements thirty or forty years later.

Even in the mid-1990s, the D436 was not a backward model, and in some aspects it was even better than similar Western products.

Its three-rotor structure has never been encountered before in China.

Judging from past experience, even if it is just to complete the localization of such a model, it may take a lot of trouble.

But since it was Chang Haonan who said this...

Ding Gaoheng still secretly raised his expectations in his heart.

"Aviation power has been the most important factor restricting the development of our aviation industry in the past few decades. If Comrade Haonan can tackle this problem this time, the turbofan 10, a third-generation engine with a thrust-weight ratio of 8, will be tackled. , our two models of domestic third-generation fighter jets will truly have no worries."

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

"Even if we look at the entire industrial history of China, this is something worth writing about."

Although he had not had much contact with Chang Haonan in the past and did not intuitively feel his abilities, a strong intuition still made him decide to set up a special preparatory group after returning, in addition to being responsible for the logistics and administrative work related to the conference. , and more importantly, keep some files, pictures and video records.

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

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

"More than just the power of a third-generation fighter."

The latter shook his head slightly:

"This time, Director Ding is asked to come forward and gather strength across the country. My further idea is to use this as an opportunity to establish a systematic development plan for the aerospace engine industry."

“In the past, our aviation engine research, including even the newly finalized turbojet 14, was technically very isolated regardless of its performance. The technical connection between different types of aircraft engines was very weak. Projects almost have to be reinvented from scratch, so the efficiency will naturally not be high.”

"In the past, we had few main engine models, so we could tolerate this. But in the future, as the types of our aviation products increase, we will also have higher requirements for the diversity of aviation power."

Having said this, Chang Haonan stretched out his hand and started counting one by one:

"Even if we ignore the situation of civil aviation for the time being and only count military weapons and equipment, then two third-generation fighter jets require afterburner thrust of 12 to 13 tons, small bypass ratio turbofan engines, bombers and transport aircraft require thrust. 13-15 ton high bypass ratio turbofan engines, new training aircraft requiring afterburner thrust of 7-8 tons of medium-sized turbofans, large unmanned aerial vehicles requiring 4-5 tons of thrust without afterburner models, cruise The missile must use a small turbojet or turbofan with a thrust of less than one ton..."

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

For many of these models, let alone projects, we don’t even have ideas yet.

But the latter did not refute——

Doesn't he want to not have so many models?

How can it be?

Is it because you didn’t have this ability in the past?

Who in charge of the aviation industry doesn't want his people to have whatever they want?

So even though Liang Zhuoping was a little bit queasy in his heart at the beginning, in the end he was attracted by the bright future described by Chang Haonan.

“So my idea is to establish a core model spectrum sequence including 4-6 levels, converted flow rates from 5kg/s to 25kg/s, and cycle power ranging from 1MW to 20MW, which is enough to derive the thrust range coverage. Various engine models ranging from 200 kilograms to 25 tons, and taking into account the different solutions of single, double and four engines, can fully meet the power requirements of most aircraft in the next 20-30 years."

"With such a core aircraft system, when a new aircraft is needed, we don't have to start from scratch like in the past, but only need to make small-scale modifications based on existing models, which will consume a lot of time and capital costs. reduce!"

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 is called painting a pie if you have low EQ, and painting a grand blueprint if you have high EQ.

It mainly depends on who specifically speaks out.

When it comes to Chang Haonan specifically, he is naturally more inclined to the latter situation.

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

After a long time, Liang Zhuoping asked tentatively.

"Of course, the current plan is to first develop a core machine with a flow rate of 25kg/s and a power level of 20MW. In addition to the turbofan 10, we can also derive a high-bypass ratio model for use on large aircraft to solve the problem. Our most urgent needs right now.”

Chang Haonan is always a down-to-earth person.

If five or six models were to go hand in hand, even he wouldn't be able to handle it.
