Chapter 378 The Road to High-Performance Aviation Engine!

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

Even though he had just guessed that the aviation industry conference that Chang Haonan applied for would definitely be held, would the decision-making speed be too fast?

But wanting to think 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 has put forward all his ideas and then asked for your opinion.

 Can you still say that I disagree?

 You don't 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 longer 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 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, Mao's thinking quickly completed its self-exculpation—

Many people have realized that, judging from this development trend, some technologies that are relatively valuable now may be conquered by others in a few years, and 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 carry out product iterations.

 Persistence may last longer.

 So since the past few 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 in the future will not even be inferior to that of the core aircraft of the Turbofan 10.

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

“It's really 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 indeed very 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 only the technology of the Soviet Union 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 a model that was not too backward, and in some aspects it was even better than similar Western products.

The three-rotor structure has never been seen before in China.

 Judging from past experience, even if such a model is only domestically produced, it will probably take a lot of trouble.

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

  Ding Gaoheng still secretly raised some 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 types of domestically produced 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 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 has a hunch that these things may become very important historical materials in the future.

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

 “More than just power for third-generation fighter jets.”

 The latter shook his head slightly:

“This time, Director Ding is asked to come forward and gather all the strength across the country. My further idea is to use this opportunity to establish a systematic development plan for the aero-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 is naturally not high.”

“In the past, we had a small number of 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.”

 Speaking of 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.

 Many of these models are not even projects, let alone projects, and we don't even have ideas yet.

 But the latter did not open his mouth to refute—

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

How can it be?

 Is it because you didn't have the ability to know in the past?

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

 So even though Liang Zhuoping was a little bit embarrassed 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 drawing a grand blueprint if you have high EQ.

 It mainly depends on who specifically said it.

 As for 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, a high-bypass ratio model for use on large aircraft can also be derived to solve the problem. Our most pressing need right now.”

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

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