Shen Wensheng was very happy and felt that he had gained a lot from this trip, not only saw the turbofan engine being developed by Tianfeng Technology Company, but also won a tailor-made turbofan engine for his regional airliner.

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

Shen Wensheng said: "Mr. Li, then it is decided, when this engine is developed, we will vigorously purchase it and install it in our ARJ21 series regional airliner." ”

Final word!

The matter is basically settled, just wait for Shen Wensheng to go back and report to his boss, after all, Shen Wensheng is not the leader of COMAC.

After the report, 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 is very happy, if nothing else, his turbofan engine, which has not yet begun to be developed, will soon have its first customer, and it is still a domestic customer, and it will be installed on a domestic regional airliner.

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

It may be that he recognized the extraordinary technical strength of Tianfeng Technology Company, or he really took a fancy to the turbofan engine of Tianfeng Technology Company.

Shen Wensheng said again: "Mr. Li, I think your turbofan engine with a thrust of 50,000 pounds is very good, and it is just right for our C919 large passenger aircraft to install this turbofan engine." ”

Li Tianfeng's eyes lit up, although C919 is far from being mass-produced, but at least it is a potential customer, Li Tianfeng said happily: "Yes, you can give it a try." At that time, we will cooperate, and after our first turbofan is developed, we will immediately install the C919 for verification. ”

"Okay, then it's settled." Shen Wensheng stood up happily and took the initiative to shake hands with Li Tianfeng, "Mr. Li." Thank you, with your engine, we don't have to worry about being stuck in the neck by others. ”

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

Everyone of Tianfeng Technology, everyone stood up one after another, even Yang Xianfeng and Liu Qingshan were no exception, everyone applauded warmly, and suddenly, the entire conference room. There was thunderous applause.

It's just that neither of them thought about it, and the things that followed were not smooth, and they almost made big waves.

…………

After sending Shen Wensheng away, Li Tianfeng began to arrange the development of his second turbofan engine, which will be a turbofan engine tailored for the ARJ21 series regional airliner.

Such a turbofan engine is certainly a first-class fourth-generation turbofan engine that will comprehensively surpass the CF34-10A engine. The thrust of a single unit is 20,000 pounds to 25,000 pounds.

Know yourself and know your opponent, and you will not be defeated in a hundred battles.

Before designing. Li Tianfeng collected a lot of technical information about the CF34-10A engine, and then, on the basis of his existing core engine, launched a comprehensive design of this engine.

The main parameters of the engine were drawn up by Li Tianfeng himself, and the design outline was not compiled by himself, but handed over to the design team led by Sun Xiaoping. According to the general framework customized by Li Tianfeng, the preparation of the design outline began.

This turbine engine is slightly smaller in size and lighter in weight, and the thrust-to-weight ratio is basically ten. Low fuel consumption, low noise and low pollution are the most basic requirements, in addition, maintainability and long life will also be the key considerations.

Civil turbofan engines, not only to consider economy, safety, but also to consider comfort, Li Tianfeng is naturally clear about these things, in the design will also focus on the overall consideration of the CF34-10A engine.

The design outline was handed over to Sun Xiaoping, and Li Tianfeng was also more assured, he already had the experience and foundation of the first turbofan engine, and the core machine had basically completed the design to be verified.

Sun Xiaoping was also very pleased to receive the design task of the new turbofan engine, and the current design institute can be described as strong and strong, and the technical strength is strong, and such a design task is not too difficult.

Tianfeng Technology Co., Ltd. is equivalent to two turbofan engines, the first with a thrust of 50,000 pounds and the second with a 20,000-pound thrust, both of which are fourth-generation turbofan engines.

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

一qiē methodical......

…………

Shen Wensheng returned to COMAC happily, and the first thing he did was to immediately report to the number one leader, Ma Delong (don't be linked to reality).

Ma Delong, who was immersed in reviewing the text, saw Shen Wensheng walk in, and immediately put down his pen, "Mr. Shen, you're back, how is the situation?" ”

Shen Wensheng said: "Chairman, I was about to report to you, this time I went to Tianfeng Technology Company, and the harvest was huge, and in the future, we no longer have to worry about being stuck by others." ”

"Oh." Ma Delong became interested, "How about the performance of the turbofan engine of Tianfeng Technology Company, is it better!" ”

"Chairman, not only excellent, it is simply very good, at first I thought they were developing a third-generation engine, but I didn't expect that it was actually a fourth-generation turbofan engine."

"What! Fourth-generation turbofan engine! Ma Delong almost stood up in shock, "Mr. Shen, is this a mistake, impossible, how can there be a fourth-generation turbofan engine in China?" ”

"Chairman, it's true, it's definitely a fourth-generation turbofan engine, there will be no fake," Then, Shen Wensheng painted a voice and reported what he learned one by one.

Thrust weight than ten!

Ultra-low fuel consumption!

Titanium hollow wide-chord fan blades!

The third generation of monocrystalline turbine blades!

Ceramic matrix composites!

……

One by one, new technologies and new materials shocked Ma Delong inexplicably, but fortunately, as the chairman, Ma Delong had a strong psychological quality and quickly calmed down.

Ma Delong asked: "Mr. Shen, this must not be mistaken, if such a new technology, new materials, is really the fourth generation turbofan engine, it is great news for us, if we are mistaken, we can only rejoice." ”

Shen Wensheng assured: "Chairman, there will be no mistake. ”

Ma Delong still can't believe that the fourth generation of turbofan engines has appeared in China, and after thinking about it, Ma Delong said: "Keep in close contact with Tianfeng Technology Company to ensure the authenticity of this engine." ”

"Hmm." Shen Wensheng nodded, "I will personally keep in touch with Tianfeng Technology Company frequently, and in addition, there is good news." ”

"Oh, what's the good news?"

Shen Wensheng said: "Chairman, the turbofan engine that Tianfeng Technology Company is developing has a thrust of 50,000 pounds, which can be installed on our C919 large passenger aircraft, and in addition, Tianfeng Technology Company promises to tailor a new turbofan engine for our Xiangfeng regional airliner." ”

Tailor-made!

Ma Delong's eyes lit up, "This is better, but I don't know how the performance of this tailor-made turbofan engine is?" ”

Shen Wensheng said: "Chairman, this turbofan engine tailored for us by Tianfeng Technology Company is promised to be the fourth generation turbofan engine, and the comprehensive performance will comprehensively surpass the CF34-10A engine. ”

Comprehensively surpass the CF34-10A engine!

Suddenly, Ma Delong's heart burst with joy, "Mr. Ma, if there is really such excellent performance, it would be great." ”

After thinking about it, Ma Delong said: "To be honest, I am skeptical about this, in addition, with a thrust level of 50,000 pounds, such a turbofan engine is very suitable for our C919 large airliner, but this engine is really excellent?" ”

The proposed engine for the C919 large passenger aircraft is the CFMLEAP-1C engine, and now, with the turbofan engine of Tianfeng Technology Company, it is very suitable.

However, Ma Delong was still slightly worried in his heart, and he was a little skeptical, Tianfeng Technology's turbofan engine was really so good?

A big question mark formed in Maderon's mind.

Coincidentally, a certain vice president of COMAC knocked on the door and came in, probably looking for Ma Delong to report to work, Ma Delong briefly said what Shen Wensheng reported just now, and then asked: "Mr. Ding, what do you think is the credibility of the matter?" ”

Vice President Ding laughed and said: "Mr. Shen, you must have been fooled by Tianfeng Technology Company, and 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, and these two turboshaft engines are not also fourth-generation engines. ”

Vice President Ding laughed again, and then said: "Mr. Shen, you are also from a technical background, how can the technical difficulty of the turboshaft engine be compared with the turbofan engine, and how is the technical difficulty of the fourth-generation turbofan engine, you should know very well in your heart." ”

Shen Wensheng was a little silent, and he also knew that Vice President Ding had been competing with him for the position of the first vice president, and he had a little bit of trouble with himself, and if he defended himself, he would only be ridiculed again.

The key now is that Shen Wensheng can't come up with evidence, and the so-called empty words are the current situation. If the turbofan engine of Tianfeng Technology Company has been designed and finalized, it will not be a problem and very convincing.

Seeing that Shen Wensheng didn't speak, Vice President Ding had a stronger smile on his face, while Ma Delong shook his head lightly and even sighed slightly.
