The turbofan 17 engine successfully obtained evidence, Li Tianfeng was full of joy, and after talking to Xu Lilong on the phone, Li Tianfeng thought about it, and still made a call to Zhang Haiping, Li Tianfeng knew that Zhang Haiping must have helped him come forward for the matter of collecting evidence.

After a phone call, Li Tianfeng said: "Director Zhang, I couldn't say a few words to you when I came to us a few days ago, let alone drink two glasses." ”

Zhang Haiping smiled heartily and said: "Mr. Li, you're polite, how about it, I know about the turbofan 17 engine production license." ”

Li Tianfeng said: "Director Zhang, the application for the production license of the turbofan 17 engine is so smooth, I know that you must have greeted the relevant departments for me, thank you so much." ”

Zhang Haiping said: "Tianfeng, this is just a gesture, the key is that your engine is very good, otherwise, if it is replaced by a bad engine, even if I come forward to say hello, it will not work." ”

Li Tianfeng smiled, Li Tianfeng was still quite satisfied with the turbofan 17 engine.

Zhang Haiping said: "Mr. Li, you also have a turbofan engine with a thrust level of 10,000 pounds, and the development of this engine is also very fast." ”

Last time, Zhang Haiping accompanied Mr. Wei to Tianfeng Technology Company for inspection, and naturally he also watched the development process of the "TFWS003" turbofan engine, and saw that the process was relatively fast, so Zhang Haiping said so.

Li Tianfeng said: "Director Zhang, this engine has entered the stage of comprehensive trial production and verification of parts, if it is fast, the first prototype will be assembled before the end of this year, and if it is slow, it will enter the assembly of the first engine in February and March next year." ”

Zhang Haiping said: "I also took a closer look at this engine, and you have adopted a lot of new materials and new designs. Although this engine is smaller than the turbofan 16 and turbofan 17 engines, it seems to be even more technical. ”

Li Tianfeng said: "This engine, based on the power of civil regional airliners, focuses on low fuel consumption, low noise and low emissions. High reliability ......"

Li Tianfeng once again gave a detailed introduction to this engine, and learned that this is a very good turbofan engine with a large signal ratio, and Zhang Haiping was very happy.

Zhang Haiping said: "Mr. Li, it is such an excellent engine, the market prospect should be good, have any customers shown their desire to purchase?" ”

"Embraer has made it clear that if the engine is developed, they will purchase it. ”

"Embraer is a good company, one of the largest regional airliner manufacturers in the world. However, you still have to open up the market, and don't just satisfy this one company. ”

Li Tianfeng nodded: "We are in contact with Bombardier, but it is more difficult. ”

Zhang Haiping reminded: "Mr. Li, do you want to consider domestic aircraft manufacturing companies? ”

Domestic, regional airliners.

The first reaction must be the ARJ21 regional airliner, and Li Tianfeng also thinks so. According to Li Tianfeng's understanding, in China. There really isn't a regional jet that fits its own "TFWS003" turbofan engine.

So, Li Tianfeng said: "Director Zhang, in China, the market for "TFWS003" turbofan engines may be relatively small. ”

Zhang Haiping said: "Mr. Li, don't look at the domestic market like this, as long as the comprehensive performance of the engine is excellent." The military also needs it. ”

The 10,000-pound level of the large duct is more than the turbofan engine The military also needs it, and when he heard this, Li Tianfeng was pleasantly surprised.

Zhang Haiping said again: "Mr. Li, I suggest you inspect the domestic market, of course." It would be even better if we could cooperate with Bombardier, which is a good regional airliner manufacturer. ”

Li Tianfeng said: "Director Zhang, in the domestic market, I am preparing to set up a market research team to conduct a detailed demand investigation, as for Bombardier, although there are certain difficulties for the time being, however, we are working hard. ”

Zhang Haiping said: "Mr. Li, if you need anything, as long as I can help, you must tell me, don't treat me as an outsider." ”

Li Tianfeng said politely: "Director Zhang, thank you first, if you need help then, I will definitely call you." ”

After chatting with Zhang Haiping for a long time, after putting down the phone, Li Tianfeng thought in his heart that the turbofan 16 and turbofan 17 engines began mass production, and his "TFWS003" turbofan engine was about to be assembled for the first prototype, and the matter of market development should really be put on the agenda.

Bombardier, thinking of this company, Li Tianfeng couldn't help but emerge again with the details of this company.

Bombardier Inc. is an international transportation equipment manufacturer headquartered in Montreal, Quebec, Canada. The main products are regional aircraft, business jets, railways and high-speed railway locomotives, urban rail transit equipment, etc.

Bombardier is also a major supplier of regional aircraft to Chinese mainland, with a total of seven domestic airlines currently purchasing Bombardier's regional airliners.

In addition, Rainbow Business Jets, a subsidiary of Bombardier, offers charter services for business jets such as the Challenger 604.

In Li Tianfeng's mind, Bombardier is the partner he needs to strive for, but the other party seems to be tepid and does not show the enthusiasm he imagined.

Thinking of Bombardier, Li Tianfeng thought in his heart that such a company must not give up, let me think about it, I must find a breakthrough.

……………

Time flies really fast, after November into December, on the test bench of the turbofan 17 engine, the first mass-produced turbofan 17 engine is being tested.

The turbofan 17 engines produced before belong to prototypes, mainly used for testing and verification, and belong to 0 or 00 batch engines, which naturally cannot be delivered to users.

This mass-produced turbofan 17 engine is the engine to be delivered to users, whether it is COMAC or Embraer, the turbofan 17 engine is needed, of which Embraer is the most demanding.

The turbofan 16 engine, which was mass-produced a few months ago, was mainly delivered to a small part of COMAC, and most of it was delivered to Embraer, which was installed in Embraer's passenger aircraft with more than 100 seats, and two aircraft per aircraft.

After the first batch of turbofan 16 engines were delivered to the Brazilian side, it may have really realized that the engines performed well, and the Brazilian side had already called several times to urge the delivery of the turbofan 17 engines.

Li Tianfeng wants his engine, whether it is a turbofan 16 engine or a turbofan 17 engine, to occupy a relatively large share of the engines purchased by Embraer, and Li Tianfeng attaches great importance to the production of these two engines.

The first turbofan 17 engine to be delivered to Embraer, the engine numbered "WS172013001", was tested at the factory test, and Li Tianfeng visited the test site and personally watched the whole process of the factory test.

The test run was very smooth, the engine performance was good, fully qualified, Li Tianfeng was very happy, and when he came back from the test engineering center, Li Tianfeng personally called the Brazilian side and informed him that the turbofan 17 engine would be delivered soon.

Naturally, the Brazilian company was also very happy, and the conversation on the phone was very pleasant.

Tianfeng Technology's third turbofan engine, that is, the "TFWS003" turbofan engine, after several months of trial production and verification of parts, many parts have completed trial production, relatively smooth, which is a surprise to Li Tianfeng.

Final assembly workshop.

Although some parts are still in trial production, many engine parts are already being assembled, such as the fan part, because a large number of parts have been successfully prototyped.

The fan part is relatively small in change, or the use of turbofan 16, turbofan 17 engines similar to the titanium alloy wide chord hollow blades, each blade is very wide.

Although the "TFWS003" turbofan engine is much smaller in weight and power than the turbofan 17 engine, the fan part is not much smaller than the turbofan 17 engine.

Because, the "TFWS003" turbofan engine is the largest bypass ratio among the three turbofan engines of Tianfeng Technology Company.

The channel ratio is 6.2, which means that it is a large fan blade, although the weight and power of this engine are much smaller than the turbofan 17 engine, but the fan is not much smaller, and it is also a large fan.

The fan casing is also a composite casing, the casing is larger, but the weight is lighter, the casing is being assembled, and the fan rotor is also being assembled.

The turbofan engine of the type "TFWS003" goes into the assembly of parts!

Two assemblers are assembling the fan rotors, weighing the fan blades one by one, carefully recording the weights one by one, and preparing for the assembly of the fan rotors.

On the triangular tenon of the fan blades, one of the workers is carefully and evenly applying a wear-resistant material with a low coefficient of friction.

The fan tray that has been dynamically balanced is placed next to it, the fan tray is not large, and the 21 tongues and grooves on the fan tray have been evenly coated with wear-resistant materials.

The fan blades, weigh them one by one, and then number them one by one, and wait a while they will be loaded into the tongue groove of the fan tray according to the number one by one, and the number can not be messed up, it must be corresponded one by one.
