Shen Wenshengda was happy and felt that he had gained a lot of money on this trip. Not only did he see Tianfeng Technology Company's turbofan engine being developed, but he also won a tailor-made turbofan engine for his regional passenger plane. ◇↓◇↓,

When he came to Tianfeng Technology Company, Shen Wensheng was so nervous that he almost didn't dare to have any great hope. Unexpectedly, Tianfeng Technology Company gave him such a big surprise.

Shen Wensheng said: "Mr. Li, that's it. After this engine is developed, we will definitely purchase it vigorously and install it on the j21 series regional passenger plane."

The final result!

The matter has basically been decided, and Shen Wensheng will only report to his boss. After all, Shen Wensheng is not the top leader of COMAC.

After reporting, if the boss agrees, the two parties have to negotiate specific details, such as price, order quantity, delivery date, technical agreement and other details.

Li Tianfeng was very happy. If nothing unexpected happens, his turbofan engine that has not yet begun to be developed will soon have the first customer, and it is a domestic customer, and will be installed on a domestic regional passenger plane.

What Li Tianfeng didn't think was that Shen Wensheng gave himself another surprise.

Maybe it was because I realized the extraordinary technical strength of Tianfeng Technology, or maybe I really like Tianfeng Technology's turbofan engine.

Shen Wensheng said again: "Mr. Li, I think your turbofan engine with a thrust of 50,000 pounds is very excellent. It is just right for our 919 large passenger aircraft to be equipped with this turbofan engine."

Li Tianfeng's eyes lit up. Although 919 is far from mass production, it is at least a potential customer. Li Tianfeng said happily: "Yes, you can give it a try. Then we will cooperate and after our first turbofan is developed, we will install 919 for verification immediately."

"Okay, then that's it." Shen Wensheng stood up happily and shook hands with Li Tianfeng on his own initiative. "Mr. Li. Thank you, with your engine, we don't have to worry about being stuck in our necks."

Li Tianfeng was very happy and shook hands with Shen Wensheng enthusiastically.

Everyone from Tianfeng Technology stood up one after another, even Yang Xianfeng and Liu Qingshan were no exception. Everyone applauded warmly, and suddenly, thunderous applause rang out in the entire conference room.

However, neither of them thought that things were going well and almost caused a lot of trouble.

…………

After seeing off Shen Wensheng, Li Tianfeng began to develop his second turbofan engine, which will be a tailor-made turbofan engine for the arj21 series regional passenger aircraft.

Such a turbofan engine is definitely a first-class fourth-generation turbofan engine, which will surpass the 34-10a engine in all respects. The thrust of a single unit is 20,000 to 25,000 pounds.

Know yourself and your enemy, and you will never be defeated in a hundred battles.

Before the design, Li Tianfeng collected a lot of technical information about the 34-10a engine, and then based on his existing core engine, he launched a comprehensive design of this engine.

The main parameters of the engine were drafted by Li Tianfeng himself. This time the design outline was not compiled personally, but was handed over to the design team led by Sun Xiaoping. Based on the general framework customized by Li Tianfeng, the design outline was compiled.

This turbine engine has a slightly smaller size, a lighter weight, and a thrust-to-weight ratio basically reaches ten. Low fuel consumption, low noise and low pollution are the most basic requirements. In addition, maintainability, long life, etc. will also be considered.

Civil turbofan engines should not only consider economics and safety, but also comfort. Li Tianfeng is naturally clear about these things, and he will also focus on comprehensively surpassing the 34-10a engine in design.

The design outline was handed over to Sun Xiaoping, and Li Tianfeng was also more at ease. He already had the experience and foundation of the first turbofan engine, and the core engine had basically completed the design and waited for verification. If Sun Xiaoping couldn't handle it, he could basically find a piece of tofu to kill him.

Sun Xiaoping was also extremely happy to receive the design task of the new turbofan engine. The current design institute is strong and has strong technical strength. Such a design task is not too difficult.

As for Tianfeng Technology, it is equivalent to launching two turbofan engines. The first thrust is 50,000 pounds and the second thrust is 20,000 pounds, both of which are the fourth-generation turbofan engines.

The design work was carried out in an orderly manner, the parts of the first turbofan engine were trial-produced, and the process verification work was carried out in an orderly manner.

Everything is orderly...

…………

Shen Wensheng returned to COMAC excitedly, and the first thing he did was to report his work to the top leader Ma Delong (do not link with reality).

Ma Delong, who was busy reviewing documents, saw Shen Wensheng coming in and immediately put down his pen, "Mr. Shen, you are back, how is the situation?"

Shen Wensheng said: "Chairman, I'm about to report to you. This time I went to Tianfeng Technology Company and gained a lot. In the future, we will no longer have to worry about being stuck by others."

"Oh." Madelong became interested, "How is the performance of the turbofan engine of Tianfeng Technology? Is it better?"

"Chairman, it's not just outstanding, it's simply excellent. At first I thought they were developing a third-generation aircraft, but I didn't expect it to be the fourth-generation turbofan engine."

"What! The fourth-generation turbofan engine!" Ma Delong stood up almost shocked, "Mr. Shen, is this a mistake? It's impossible. How could there be a fourth-generation turbofan engine in China?"

"Chairman, it's true, it's definitely the fourth-generation turbofan engine, there will be no fakes," then Shen Wensheng reported on what he learned one by one.

Thumbs and weights are 10!

Ultra-low fuel consumption!

Titanium alloy hollow wide-string fan blades!

Third-generation single crystal turbine blades!

Ceramic matrix composite material!

...

One by one, new technologies and new materials shocked Ma Delong inexplicably. Fortunately, as the chairman, Ma Delong had excellent psychological qualities and quickly calmed down.

Ma Delong asked: "Mr. Shen, this must not be mistaken. If such new technology and materials are really adopted, it is really the fourth-generation turbofan engine, which is great news for us. If we make mistakes, we will only be happy."

Shen Wensheng promised: "Chairman, you will never make any mistakes."

Madelong still couldn't believe that the fourth generation of turbofan engines actually appeared in China. After thinking about it, Madelong said: "Keep in close contact with Tianfeng Technology to ensure the authenticity of this engine."

"Yeah." Shen Wensheng nodded, "I will keep in touch with Tianfeng Technology Company in person, and there is also good news."

"Oh, what good news?"

Shen Wensheng said: "Chairman, the turbofan engine that Tianfeng Technology is developing has a thrust of 50,000 pounds, and can be fully installed on a large passenger plane of 919. In addition, Tianfeng Technology Company promises to tailor a new turbofan engine for our Xiang-Feng regional passenger plane."

Tailored!

Madron's eyes lit up, "This is better, I just don't know how the performance of this turbofan engine tailored is?"

Shen Wensheng said: "Chairman, Tianfeng Technology Company has tailored this turbofan engine for us. It promises to be the fourth generation turbofan engine, and its comprehensive performance will exceed the 34-10a engine in all aspects."

Total surpass 34-10a engines!

Suddenly, Ma Delong felt happy, "Mr. Ma, it would be great if he really had such excellent performance."

After thinking about it, Ma Delong said: "To be honest, I am skeptical of this. In addition, with a 50,000-pound thrust level, it is very suitable for such a turbofan engine to be equipped with our 919 large passenger aircraft. However, this engine is really better?"

The engine that the 919 large passenger aircraft intends to use is the mleap-1 engine. Now, with the turbofan engine of Tianfeng Technology, it is just very suitable.

However, Ma Delong was still slightly worried and a little skeptical. Tianfeng Technology's turbofan engine is really so outstanding?

A big question mark formed in Madron's mind.

It happened that a deputy general of COMAC knocked in and might be asking Ma Delong to report his work. Ma Delong briefly said what Shen Wensheng had just reported, and then asked: "Mr. Ding, how do you think the credibility of the matter?"

Vice President Ding laughed and said, "Mr. Shen, you must have been fooled by Tianfeng Technology Company. You are not unclear about the strength of the domestic aviation industry. The fourth-generation turbofan engine? How is this possible?"

Shen Wensheng was a little anxious and immediately said loudly: "Mr. Ding, you can't say that. Tianfeng Technology Company has not successfully developed the turboshaft D and turboshaft e engines. Are these two turboshaft engines also the fourth generation engines."

Vice President Ding laughed again and said, "Mr. Shen, you are also a technical background. How can the technical difficulty of the turboshaft engine be compared with the turbofan engine? You should be very clear about the technical difficulty of the fourth-generation turbofan engine."

Shen Wensheng was a little silent, and knew that Vice President Ding had been competing with him for the position of First Vice President, and had a little inconsistent with him. If he defended himself, he would only be ridiculed again.

The key now is that Shen Wensheng cannot provide evidence. The so-called empty talk is the current situation. If Tianfeng Technology Company's turbofan engine has been designed and finalized, then everything will not be a problem and is extremely convincing.

Seeing that Shen Wensheng didn't say anything, Vice President Ding smiled even stronger, while Ma Delong shook his head gently and even sighed slightly.
