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 aviation industry conference that Chang Haonan applied for would definitely be held, was it too fast to make a decision?
But after thinking about it, he nodded quickly;
"Of course Linyu can do it. I will start arranging the relevant preparations for the meeting after I get back."
Just kidding, the leader puts forward all his ideas and then asks for your opinion.
Can you still say that I disagree?
If you disagree, 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 my country for production at the same time, it will be beneficial to the field of aviation power. Development will also be a promotion, so I think we can wait a little for the specific date of this meeting."
After receiving Liang Zhuoping's reply, Ding Gaoheng turned to Chang Haonan and said:
"But don't worry, it won't take a long time."
"Is it so smooth?"
The strategy of killing three people with two peaches was also based on the negotiation process of the introduction of high-speed rail in the previous life, but even Chang Hao Nan himself didn't expect the effect to be so immediate.
“Yes, according to the feedback from Lao Huai after his visit to Zaporizhia two days ago, the situation in Ermao is worse than we previously expected, so Ivchenko - Progress Company quickly chose to compromise when faced with the risk of completely losing the opportunity to participate in cooperation. Later, the two manufacturing plants in Ufa and Moscow also gave in a small symbolic step. At present, there is no fundamental conflict between the two parties, 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 make further improvements with the funds we provided when we introduced it.”
In fact, after receiving a series of huge stimulations from China, especially when I learned that China and the European Aviation Administration had successfully signed. After the Airworthiness Mutual Recognition Agreement was signed, Damao’s thinking quickly completed its self-exculpation——
Many people have realized that based on this development trend, some technologies that are still relatively valuable may not be In a few years, others will conquer it on their own. Continuing to raise prices will bring too great a risk.
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.
Persistence may last 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 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 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."< br>
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 as the aviation power for almost all domestically produced main fighter aircraft.
But in the final analysis, it is only the technology of the Soviet Union in the early 1950s. It is not 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 considered backward, and was even better than similar Western products in some aspects of performance.
Its three-rotor structure has never been seen before in China.
Based on past experience, even if such a model is only domestically produced, it may take a lot of trouble.
But since Chang Haonan said this...
Ding Gaoheng still secretly raised his expectations in his heart.
“Aviation power, in the past few decades, has been the most important factor restricting the development of our aviation industry. If Comrade Haonan can this time put the turbofan 10 into the third place with a weight higher than 8 Now that we have solved the problem, our two types 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 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 I didn't have much contact with Chang Haonan in the past, I didn't feel it intuitively. It exceeded the other party's ability, but 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 meeting, more importantly, it was to retain 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:
"It's not just the power of third-generation fighter jets."
The latter shook his head slightly:
"This time, I asked Director Ding to come forward and concentrate the power nationwide, I will go one step further The idea is to use this as an opportunity to establish a systematic aero-engine industry development plan.”
“Our previous aero-engine research even included the turbojet 14 that had just been finalized, regardless of its performance. There is a strong isolation in technology, and the technical connection between different types of aviation engines is very weak. Every project has to be reinvented from scratch, and the efficiency is naturally not high."
"In the past. We have a small number of main engine models, so we can tolerate this. However, as our aviation product types increase in the future, 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 the two third-generation fighter jets need to be pushed harder. Small bypass ratio turbofan engines with a thrust of 12 to 13 tons, bombers and transport aircraft require large bypass ratio turbofan engines with a thrust of 13-15 tons, and new trainer aircraft require medium-sized turbofan engines with an afterburner thrust of 7-8 tons. Fans and large UAVs require models without afterburner with a thrust of 4-5 tons, and cruise missiles require small turbojet or turbofans with a thrust of less than one ton..."
Chang Haonan's inventory Liang Zhuoping was a little unbearable.
Many of these models, not to mention projects, don’t even have ideas yet.
But the latter did not refute——
Doesn't he want to not have so many models?
How is that possible?
You didn’t have this ability in the past, right?
Which person 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 complaining 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, taking into account the different options 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, there is no need to start research from scratch as in the past, but only need to make small-scale modifications based on existing models, which will consume less time and capital costs. Greatly reduced!"
Both Ding Gaoheng and Liang Zhuoping were silent.
The amount of information is relatively large and takes some time to digest.
This kind of thing, if you have low emotional intelligence, it is called painting a cake, while if you have high emotional intelligence, it is called drawing a grand blueprint.
It mainly depends on who specifically speaks out.
As for Chang Haonan specifically, he is naturally more inclined to the latter situation.
"I'm afraid this process should 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 one for use on large aircraft. The high bypass ratio model solves our most urgent needs. ”
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.
