Li Tianfeng heard someone calling him, and the voice seemed to be relatively familiar, so he couldn't help but look back, and immediately walked over.

"Minister Liu, you call me."

The last test flight of the 8K Shun lì, Minister Liu was deeply impressed by Li Tianfeng, and spoke highly of the turbofan 16 engine.

Minister Liu said: "Mr. Li, let's go, go to the next room and sit down, let's talk." ”

Li Tianfeng nodded, Minister Liu chatted with him, it was definitely not a family affair, it must be to talk about some aero engine things, so Li Tianfeng said to Sun Xiaoping, who came to the meeting with him: "Mr. Sun, you go back to the hotel first." ”

Sun Xiaoping nodded a little and returned to the hotel where he stayed without mentioning it.

Minister Liu said enthusiastically: "Mr. Li, let's go, let's go to the reception room next door, where there is an old friend of yours." ”

Li Tianfeng thought about it in his heart, and immediately guessed who it was, so Li Tianfeng nodded and said, "Minister Liu, then let's go next door." ”

The two walked into the reception room next door, Li Tianfeng saw Zhang Haiping, and Li Tianfeng said, "Director Zhang, I guess it should be you." ”

Zhang Haiping said enthusiastically: "Mr. Li, come, sit down." ”

Everyone sat down and exchanged a few words, Minister Liu asked about the scientific research, production and operation of Tianfeng Technology Company with more concern, and then, Minister Liu said: "Mr. Li, your Tianfeng Technology Company has only been established for four years now. ”

Li Tianfeng said: "Minister Liu, from its establishment in 2009 to the present, it has been four years and one month. ”

Minister Liu said: "Mr. Li, you have created a miracle in the history of the aviation industry, in just four years, the vortex shaft D, the vortex shaft E, and the turbofan 16. One engine after another has been developed by you, and in addition, I heard that you have two turbofan engines that are about to be developed, which is amazing. ”

Highly praised by Minister Liu, Li Tianfeng was very happy in his heart, and Li Tianfeng said: "Minister Liu." Our 'TFWS002' and 'TFWS003' turbofan engines, one with a thrust class of 20,000 pounds and the other with a thrust of 10,000 pounds......"

Li Tianfeng made a comprehensive introduction to the two turbofan engines, their overall performance, and development progress.

Minister Liu nodded and said, "Not bad, not bad." ”

Zhang Haiping also said: "Minister Liu, Tianfeng Technology Company is a very good large-scale aviation industry enterprise in our country, my personal opinion, our military's scientific research funds can be appropriately tilted towards Tianfeng Technology Company." ”

Minister Liu nodded and said, "I personally agree with this. This can be submitted for discussion. ”

After speaking, Minister Liu said: "Mr. Li, the technical review meeting you also participated in just now, our H-6 is too old and embarrassing, and we don't have an excellent long-range bomber, so we can only continue to modify and upgrade on the basis of H-6, hey." It's really a helpless move! ”

After speaking, Minister Liu sighed softly. Judging from Minister Liu's tone and demeanor, Li Tianfeng could fully understand the military's need for an advanced long-range bomber.

Li Tianfeng thought in his heart, Minister Liu was chatting with him today, he should be preparing to launch his own long-range strategic bomber project, this, this is too shocking!

Soon. Li Tianfeng waved this idea out of his mind, this is absolutely impossible, and the people in the military are not stupid, how can they give such a task that they are almost unable to complete at present.

Li Tianfeng said: "Minister Liu, our bombardment is indeed relatively old. Compared with the current B52 in the United States, it is too far and too far behind. ”

Li Tianfeng used two "too far" in a row, which shows that Li Tianfeng really thinks that the bombardment six is old.

Minister Liu said: "The H-6 is too old, but the strength of our domestic aviation industry, the research and development of a new type of bomber, is not realistic in a short period of time, perhaps, waiting for my retirement, we do not have a new type of bomber." ”

After shaking his head slightly, Minister Liu said: "Don't talk about this, it's a little far, Mr. Li, I came to you this time, I want to consult your opinion on some things." ”

Li Tianfeng thought in his heart, sure enough, he was about to get to the point.

Minister Liu said: "Mr. Li, since you have the strength to successfully develop a large channel ratio turbofan engine, you must also have the technical strength to develop an excellent small channel ratio turbofan engine. ”

The turbofan engine is widely used in fighter jets because of its small windward area, high thrust and higher fuel efficiency than turbojet engines.

For example, the American F119 turbofan engine, a typical small-channel ratio turbofan engine, is used in the American F22 fighter.

Hearing this, Li Tianfeng thought in his heart, is it to let himself develop a small signal ratio turbofan engine for the J-20 fighter.

Sure enough, Minister Liu said: "Mr. Li, our new fighter J-20 has successfully completed a series of test flights, the table is good, but the engine is a hard injury, it is equipped with an engine imported from Russia, if there is an excellent domestic engine, it would be great." ”

Li Tianfeng said: "Minister Liu, isn't it the development of the turbofan 15 engine that a large domestic aviation industry enterprise has launched, and the turbofan 15 will be used as the power of the J-20. ”

The turbofan 15 engine, codenamed "Emei", was established and designed earlier than the turbofan 16 of Tianfeng Technology Company, but the development progress is obviously lagging behind.

Minister Liu said: "There are many problems exposed in the development process of the turbofan 15 engine, and it may take a long time to really develop it. ”

Li Tianfeng thought about it, and combined with the actual situation of Tianfeng Technology Company, Li Tianfeng said: "If we can develop power for the J-20, it is our honor, but we have never developed a small signal ratio turbofan engine, and directly developed an engine for the J-20, and the www.biquge.info of Biquge is a little high." ”

Li Tianfeng is modest, in Li Tianfeng's opinion, it is best to develop a small channel ratio turbofan engine with slightly lower requirements, and practice it.

Minister Liu said: "The www.biquge.info of Biquge is indeed a bit high, and I and the leaders have reflected it, but you must be prepared, maybe you will receive a direct research and development order from our military to start the development of a small signal ratio turbofan engine." ”

Li Tianfeng said: "We have two turbofan engines in our hands are being developed, and we are about to apply for design finalization and production model licensing. ”

Minister Liu said: "You, you, you will really take advantage of the time to reach out, okay, these things of yours, I will try to help you say hello." ”

Li Tianfeng laughed......

………

After returning from the capital, Li Tianfeng was still thinking about the conversation with Minister Liu, and Li Tianfeng had a hunch that it would not take a few months, and he might receive the task of developing a military small signal turbofan engine before the end of this year at the earliest.

It's just that I don't know which fighter to develop the engine for, in fact, in Li Tianfeng's mind, it is best to develop an excellent engine for the J-10, starting with the J-10, and then marching to the more demanding J-20.

As a main fighter of the military, the J-10 has naturally realized the localization of the engine, and the "Taihang" engine is the power of the J-10.

However, the "Taihang" engine is the third generation of small channel ratio turbofan engine, if it is replaced by Tianfeng Technology Company for the development of this engine, Li Tianfeng must have developed the fourth generation of small channel ratio turbofan engine.

However, from Minister Liu's conversation, Li Tianfeng knew that if the military wanted to develop the engine of a certain fighter on its own, it would definitely directly issue the task of developing it, and whether it was the power of the Jian-10 or the Jian-20, and he could only listen to the military.

After thinking about these things, Li Tianfeng couldn't help but shake his head, it was too early for him to think deeply about these problems, and then he would receive the research and development task assigned by the military.

"Let's go and take a look at our TFWS002 engine." So, Li Tianfeng stepped out of his office and walked towards the final assembly workshop.

During Li Tianfeng's Jing period, this engine has completed the first verification test run, and the table is very perfect, and the number of test runs is very good, and Li Tianfeng has received a phone report.

The engine has now been disassembled, the parts have been cleaned, and a series of inspections have been completed before it is ready to be reassembled and tested again.

Walking into the assembly workshop, I saw that the huge assembly plant has been fully utilized, with turboshaft D, turboshaft E engine assembly area, turbofan 16 assembly area, as well as 'TFWS002' engine, 'TFWS003' engine assembly area and so on.

Li Tianfeng glanced around at the huge assembly workshop and thought in his heart that if another engine was developed, another assembly workshop would be built.

Walking to the 'TFWS002' engine assembly area, Li Tianfeng saw a series of parts neatly placed on the workbench at a glance, which was the first 'TFWS002' engine, which had undergone the first verification test.

Sun Xiaoping happened to be there, and he came earlier than Li Tianfeng, Li Tianfeng asked: "Mr. Sun, how is the situation of each part after the test?" ”

Sun Xiaoping said: "All parts have completed strict inspection, and they are in very good condition, and they can be assembled again for the second round of verification and testing." ”

Li Tianfeng read a lot of parts inspection reports with great interest, and also looked at the physical situation of many key and important parts, especially the situation of hot parts such as turbine blades, turbine disks, and flame cylinders.

After reading this, Li Tianfeng was about to leave, the phone rang, and when he looked at the caller ID, Li Tianfeng couldn't help but smile slightly.
