Tianfeng Technology Company.

Since the advent of the "Hercules" material, Li Tianfeng has not worried about the material being copied by other countries, on the contrary, it is widely used in the field of aero engine and aircraft manufacturing.

Li Tianfeng did not care too much, as long as the core secret is in his own hands, others will not be able to produce and manufacture this material, recently, Li Tianfeng's main focus is on the development of J-18 fighters and J-30 fighters.

Among them, the J-30 fighter is the focus of the focus, with the completion of the assembly of the first static testing machine, into the structural strength static test, marking the development of this fighter, into the comprehensive test stage.

The trial production of each part is not mentioned for the time being, and there is basically no need for Li Tianfeng to care, naturally there are the following technical personnel to do a good job in this regard, Li Tianfeng only needs to pay attention to several important tests, such as static test, avionics system performance test and so on.

Since the assembly of the first static testing machine was completed last time, the test has been carried out quickly, and now the test has been basically completed, and the test report has been formed one by one.

Li Tianfeng came to the No. 2 assembly workshop again, and looked at the first static testing machine, next to Li Tianfeng, Lei Yong was reporting work.

Lei Yong said: "Boss, the first static test was basically successful, but we also found a lot of problems, in terms of design, or manufacturing process, we need to further improve." ”

Li Tianfeng took a large stack of test reports given to him by Lei Yong, roughly flipped through them, and then, Li Tianfeng said: "Mr. Lei, there are no big problems, but there are a few problems that we still need to pay attention to, such as ......"

Li Tianfeng pointed out several issues that need to be paid attention to one by one and put forward his own opinions. It can be seen from the expression on Li Tianfeng's face that Li Tianfeng is quite satisfied with the results of the first static test.

Just as he was pointing at Lei Yong, Li Tianfeng's phone rang, and Li Tianfeng saw that it was a text message sent by Sun Xiaoping. The first draft of the design technical outline for the new 100,000-pound thrust-rated large-channel ratio turbofan engine has been prepared.

Li Tianfeng looked at the text message, and his heart was happy, Li Tianfeng basically did not interfere in the preparation of this design technical outline, and it was completely completed by the R&D team led by Sun Xiaoping.

Seeing Lei Yong looking at him, Li Tianfeng said, "Mr. Lei." The design technical outline for our 100,000 pound thrust class engine has been preliminarily prepared. ”

Hearing this, Lei Yong was overjoyed. The research and development of this engine is not a secret in Tianfeng Technology Company, and Lei Yong naturally knows it.

Lei Yong said: "Boss, such an engine is really exciting, I don't know what kind of engine it will be." ”

What kind of engine will it be? This is not only the expectation of Lei Yong alone, almost all employees of Tianfeng Technology Company. Ever since we knew that the company was preparing to develop such an engine, everyone was looking forward to it.

Quite a few even speculated. It must have been a very good engine, because there was an example of the turbofan 21 engine in front of it, and the expectations for this engine were high.

Li Tianfeng said: "What kind of engine it is, everyone will know soon, and it will definitely not disappoint everyone." ”

The design and technical outline of this engine has been preliminarily compiled, and Li Tianfeng also wants to take a look. What does this outline compiled by Sun Xiaoping look like, and does it meet the requirements in his heart?

So, Li Tianfeng said to Lei Yong: "Mr. Lei, you have bothered a lot about the development of the J-30 fighter." If anything, come to me directly. ”

Lei Yong hurriedly nodded and said: "Boss, there is no problem, we will pay close attention to the development process, if there is any problem that cannot be solved, I will ask you for advice as soon as possible." ”

Lei Yong used to be an extremely conceited person in terms of technology, but since he found out that there was a gap between him and Li Tianfeng in terms of technical level, Lei Yong has become much more modest.

The current Lei Yong is very humble in front of Li Tianfeng, and if there are any technical problems that he can't solve, he is not ashamed to ask, and often asks Li Tianfeng.

Lei Yong's mentality is very good, and he often asks Li Tianfeng for advice, and Li Tianfeng also knows everything, and often teaches with his heart, Lei Yong's technical level has improved a lot compared with when he first joined Tianfeng Technology Company.

In Li Tianfeng's eyes, Lei Yong can fully act as his technical assistant, the development of J-18 and J-30 fighters, many things Li Tianfeng let Lei Yong do.

After explaining a few words to Lei Yong, Li Tianfeng left the Chengnan base with peace of mind, and soon after returning to his own office in the headquarters of Tianfeng Technology Company, Sun Xiaoping came in with the first draft of the design outline.

Sun Xiaoping said: "Boss, this is the design outline we have prepared, it is only the first draft, and there are some places that still need to be consulted by you." ”

Li Tianfeng took the first draft of the design outline and said enthusiastically: "Mr. Sun, you sit down first, and I will take a look at this outline first." ”

After speaking, Li Tianfeng read it carefully, while Sun Xiaoping sat down as he said, waiting for Li Tianfeng to finish reading the design technical outline.

Thrust: 65,000 lbs-150,000 lbs (rated thrust 100,000 lbs).

Total pressure ratio: 45.

Channel-to-channel ratio: 5.2.

Fan diameter: 3.6 meters.

Thrust-to-weight ratio: 12.

Engine weight: 12500 lbs.

Inlet Air Flow: ......

……

Li Tianfeng read this design technical outline for a long time, obviously looked at it very carefully, and while looking at it, he also took out a pen and pointed out the places that needed to be revised and improved one by one.

After a long time, Li Tianfeng put down this technical outline, and Li Tianfeng said: "Mr. Sun, on the whole, I am quite satisfied, and I have basically met my requirements, but there are some places that still need to be improved, such as ......"

Li Tianfeng explained the areas that needed to be improved and perfected one by one, and Sun Xiaoping listened to them, explained them more carefully, and even talked about the reasons why they should be perfected and improved in this way.

If you do not develop a new engine, once you start developing, the positioning and starting point will be very high, obviously, Sun Xiaoping is also aware of this aspect, in the design technology outline, the positioning of this engine is very high, and the use of Tianfeng Technology Company's second-generation core machine technology.

Sun Xiaoping's positioning is that this engine will be ahead of Rolls-Royce's Ruida 900 engine and GE's GP7000 engine.

Whether it is the Ruida 900 or the current GP7000 engine, it is the engine of the current Airbus A380 passenger aircraft.

An Airbus A380 passenger plane uses four such engines, each with a thrust of about 7 to 80,000 pounds, both of which are world-renowned large turbofan engines.

It can be seen in the design technical outline that the two engines designed by Sun Xiaoping can meet the needs of giants like A380, and the rest of the performance parameters also surpass the Ruida 900 and GP7000 engines.

Li Tianfeng said: "Our engine will be the world's lightest, cleanest, most reliable, lowest noise engine, in terms of every pound of thrust, among all the world's large turbofan engines, its fuel consumption will be the smallest, emissions are also the smallest." ”

Hearing this, Sun Xiaoping was secretly surprised, originally, Sun Xiaoping thought that his design starting point was relatively high, but he didn't think about it, Li Tianfeng put forward higher requirements.

In the office, Sun Xiaoping stayed for a long time, and even after getting off work for a long time, there were not many people in the entire Tianfeng Technology Company factory, and Sun Xiaoping walked out of Li Tianfeng's office.

When he walked out, Sun Xiaoping held this design technical outline densely written with words and parameters in his hand.

Although this design technical outline has basically reached Li Tianfeng's satisfaction, it still needs to be optimized and improved in many aspects.

After staying in Li Tianfeng's office for so long, Sun Xiaoping also asked Li Tianfeng a lot of technical questions about the design of this engine.

Now, Sun Xiaoping basically understands some things that he doesn't understand and can't grasp, and he has greater grasp and confidence in the development of this engine.

Next, Sun Xiaoping led his team to improve and modify the design technical outline again, and the improved design technical outline was basically perfected and fully met Li Tianfeng's requirements.

This design technical outline was reviewed internally by Tianfeng Technology Co., Ltd., and after being slightly improved again, Li Tianfeng personally signed it.

Sun Xiaoping led everyone to start the development of this engine......

Recently, many employees have found that it seems that Li Tianfeng has not been seen for several days, and many employees are even speculating about what Mr. Li has been busy with recently and why he has not shown up.

Li Tianfeng did not show up, mainly because Li Tianfeng had not been in Tianfeng Technology Company for the past few days, and Li Tianfeng went on a trip abroad.

Li Tianfeng went abroad, naturally to promote and promote his own big engine, even if this engine can only complete the design technical outline, the design work can be started, but it does not prevent Li Tianfeng from selling.

Li Tianfeng went to Airbus and Boeing, met with the executives of these two companies, and had a good pitch.

This time, Li Tianfeng was fully prepared and prepared a lot of information, such as the basic performance parameters of this engine, and even the 3D color map drawn by the computer.

A few days later, Li Tianfeng returned to Tianfeng Technology Company, after Li Tianfeng came back, he looked good, and seemed to be in a happy mood.
