Capital.

Li Tianfeng, Sun Xiaoping, and Liu Wei walked out of the airport, and outside the airport, there was already a military vehicle waiting, and the three of them got into the car and drove directly towards a certain military hotel, which was the hotel where the military arranged for everyone to stay.

Liu Wei said: "Boss, the military will really directly issue us with research and development tasks." ”

Li Tianfeng nodded, "If nothing else, the military will directly issue us with the task of developing a military turbofan." ”

Sun Xiaoping said: "Boss, the military turbofan should be a small signal than a turbofan engine, I don't know which fighter is the power." ”

Li Tianfeng is not very clear, Zhang Haiping pays attention to the confidentiality regulations, but he didn't elaborate, everything will be said after Li Tianfeng arrives in the capital, which makes Li Tianfeng full of curiosity, and Sun Xiaoping is the same, he has been guessing what kind of engine this is.

Liu Wei said: "Boss, the military didn't let us develop the power of the J-20!" After speaking, Liu Wei's eyes could not hide the excitement.

Sun Xiaoping also looked at Li Tianfeng in surprise, and Sun Xiaoping said: "Boss, if it is to develop power for the J-20 fighter, it will be too difficult, and I am not so sure." ”

Li Tianfeng smiled and said: "The military should not put forward such high requirements, I estimate that eighty percent is the power of a certain fighter in service, such as our J-10 is still powered by the Russian-made AL-31F engine." ”

Sun Xiaoping said: "If it is really a tailor-made engine for the J-10, it is still a little less difficult in terms of difficulty, but because it is a small signal than a military turbofan engine, the difficulty of development is not small." ”

Li Tianfeng smiled and said: "Director Sun, didn't you preside over the development of the turbofan B engine before, and this is also a small signal ratio turbofan engine." ”

Sun Xiaoping said: "Boss, that's different, although the turbofan B engine is also a small signal than the turbofan engine. But that is only the power of a certain training aircraft, and the power of a fighter plane is not the same, in addition, the turbofan B engine is a mapping and imitation of a certain Russian engine, in terms of development, the difficulty is much less. ”

Li Tianfeng smiled. Said confidently: "Director Sun, we must have enough confidence, this time we may still compete with AVIC Group." ”

Sun Xiaoping took a look at Li Tianfeng, and then said: "Boss, we are not afraid of you with you, our company's entire design team has enough confidence." ”

Seeing this, Liu Wei smiled, and there was a slight admiration in her eyes, and Liu Wei also knew it. In terms of technology, Li Tianfeng is the optimus prime in everyone's minds, supporting the entire blue sky of Tianfeng Technology Company.

The next day, a conference room of the military.

In the conference room, there are not only several senior executives of AVIC Group, but also Li Tianfeng and his party, Li Tianfeng, Sun Xiaoping, and Liu Wei represent Tianfeng Technology Company, as for military personnel. Because of the time, it is not yet the official time. And it didn't show up.

In the conference room, Li Tianfeng was chatting with Mr. Lin of AVIC Group, and it was not the first time for the two to meet, the last time they were in Zhang Haiping's office, the two had met for the first time.

The two politely greeted each other, although the two sides were in a competitive relationship. But this is normal business competition, and there is no tense atmosphere, on the contrary, the chat between the two is quite relaxed.

Li Tianfeng said: "Mr. Lin, our turbofan 16 and turbofan 17 engines. You're more satisfied! ”

Mr. Lin smiled and said: "Mr. Li, listening to the reaction of the comrades of COMAC, these two engines are very good, and we are very satisfied." ”

Hearing this, Li Tianfeng smiled happily, looking rather happy.

Mr. Lin said: "Mr. Li, when we were in Director Zhang's office last year, you promised to deliver these two engines in batches before the end of last year, and I was still full of worries at that time, worried that you would not be able to fulfill your promise. ”

Li Tianfeng said proudly: "Mr. Lin, how about it, we talked and counted, and successfully realized the batch delivery of these two engines in accordance with the original commitment." ”

To be honest, the two engines can be delivered so smoothly, on the one hand, the entire development process is relatively smooth, and there are few problems exposed, and on the other hand, Li Tianfeng really grasps it tightly.

Mr. Lin said: "Mr. Li, you are really amazing, you have achieved mass production of these two engines in such a short period of time, I can't imagine it." ”

Li Tianfeng said: "Mr. Lin, the performance of our engines is okay, so in the future, will the aircraft of COMAC be equipped with our engines or continue to be equipped with imported engines?" ”

Mr. Lin didn't want to think about it, and waved his hand and said: "The aircraft of COMAC, whether it is an ARJ21 regional airliner or our C919 airliner, are all equipped with domestic engines, and all of them are turbofan 16 or turbofan 17 engines. ”

Li Tianfeng jokingly said: "Mr. Lin, are you not afraid that GE will find trouble?" ”

Mr. Lin smiled and said, "What are you afraid of, don't you have your engine, even if GE breaks off cooperation with us, we are not afraid." ”

Li Tianfeng said: "Okay, Mr. Lin, if there is anything to find me in the future, as long as I can help, I will do my best, including technical things." ”

The two gradually talked happily with each other, and unconsciously, the two talked about the engine development task that the military was about to issue.

Mr. Lin said: "Mr. Li, this time the military will give us research and development tasks, we will start a competition, whose engine is excellent, whose engine will be used at that time, Mr. Li, what do you think?" ”

Li Tianfeng said: "Mr. Lin, we are under a lot of pressure to compete with a super large company like you, and when the time comes, you have to give in a little." ”

Mr. Lin laughed, and then said: "Mr. Li, you have successfully developed three Dahan Daobi turbofan engines, and all of them are fourth-generation engines, and you already have enough experience, so you are too modest." ”

Li Tianfeng also laughed, although it was competition, it did not affect the harmony between the two sides.

The two chatted, and at nine o'clock in the morning, the military party entered the conference room, led by a major general, and the military personnel were seated, and the meeting officially began.

Comrade Major General first gave a briefing on the current situation of the Jian-10 and Jian-11, with a particular focus on the engines of these two fighters, and then introduced the situation of the new aero engine to be developed next.

Comrade Major General said: "This new aero engine, which is about to be developed, will be developed by AVIC Group and Tianfeng Science and Technology Company at the same time, and it is required to fully complete the design by the end of this year and complete the final assembly of the first prototype by the end of next year." ”

This is equivalent to two years, this year and next year, within two years, the final assembly of the first prototype will be completed, in terms of time, it is very urgent.

Everyone from AVIC Group who participated in the meeting quietly glanced at each other, and they all clearly felt the urgency of time. The people of Tianfeng Technology Company have a relatively normal face, and two years, Li Tianfeng's opinion, should be enough.

Comrade Major General ignored the reaction of the AVIC Group and continued: "This engine is the fourth-generation small signal turbofan engine, which will be mainly used for the power of the J-10 in the future, and can also be used for the J-11. ”

Fourth-generation small signal channel ratio turbofan engine!

The people on the AVIC side were slightly surprised, they didn't expect the starting point to be so high, and they suddenly felt a lot of pressure, and some people even raised objections immediately.

"I'm sorry, I'll interrupt, in the absence of a suitable core engine or a reference engine, to start the development of the fourth generation of small channel ratio turbofan engine at once, is the starting point too high, to complete the development of such an engine within two years, I think it is too difficult for us."

The current situation in China, almost every aero engine research and development, is surveying and mapping or imitation, even the "Taihang" engine with independent intellectual property rights, is also improved on the basis of American technology.

In the 80s, when Sino-US relations improved, China imported from the United States the same level as the F100 to the aviation to land gas turbines, which is one of the important technical sources of the core engine of the "Taihang" engine; The second is self-research and improvement. Only then did we have the current "Taihang" engine.

Seeing that AVIC Group's reaction was so big, Comrade Major General couldn't help asking: "Mr. Li, do you have any objections?" ”

Li Tianfeng smiled and said, "We don't have any problems with Tianfeng Technology Company for the time being. ”

Comrade Major General nodded with satisfaction, and many people in the AVIC Group looked at Li Tianfeng in surprise, but they didn't expect Li Tianfeng to be so confident.

Comrade Major General continued: "This is a technical plan drawn up by our military, and the engine you develop must meet or exceed the requirements of this technical plan. ”

After speaking, Comrade Major General waved his hand, and a colonel gave the technical solution to AVIC Group and Tianfeng Technology Company respectively, and Li Tianfeng, on behalf of Tianfeng Technology Company, took over this technical plan from the colonel.

This was the first time Li Tianfeng had seen this technical plan drawn up by the military, and even Zhang Haiping did not mention the specific content of the technical plan in his previous phone call.

Li Tianfeng took this technical solution, and when he saw the word "top secret" on the cover, he couldn't help but feel a pang in his heart, this is the highest secret, the highest level of secrecy.

Sure enough, the major general said solemnly: "This is our top-secret document, you must keep it properly and strictly prohibit leaking secrets, otherwise, you will be severely punished by discipline." ”

Li Tianfeng nodded solemnly, seeing the word "top secret" and seeing the bright red seal of the military, Li Tianfeng also felt the weight of this document.

Li Tianfeng solemnly looked at this document, and the specific requirements and performance parameters of the engine to be developed by the military were imprinted into Li Tianfeng's eyes one by one.
