Because it is the first prototype of the "TFWS003" turbofan engine, the assembly of the fan rotor is very careful, adhering to the principle of excellence, and trying to assemble the rotor to make the quality more perfect.

The first prototype, some parts into the assembly, Li Tianfeng naturally paid more attention, for this engine, Li Tianfeng attaches great importance to this, no, Li Tianfeng has entered the assembly workshop, directly towards the TFWS003" turbofan engine parts assembly area.

Li Tianfeng walked to the fan rotor assembly area and saw two assembly workers assembling the fan rotor, Li Tianfeng couldn't help but take two steps forward and walked to the assembly workbench.

Seeing Li Tianfeng, the two assembly workers who were working hurriedly put down the things in their hands and said with a little respect: "Mr. Li, hello." ”

Li Tianfeng hurriedly said politely: "It's okay, you're busy, I'll just take a look." ”

After speaking, Li Tianfeng looked at the appearance and quality of these parts, then looked at the weighing of the blades, and even looked at the numbering of the blades and the tenon groove of the fan pan.

In order to ensure that the mass distribution of the fan rotor is as uniform as possible after assembly, the fan blades are weighed, the fan tray is dynamically balanced, and the key positions of the quality are found, and then the counterweight is carried out to number the fan blades.

After looking at the numbering of these blades, Li Tianfeng reminded: "Master Lu, I think that the No. 6 blade and the No. 11 blade will be reversed, so that the effect may be better, and the dynamic balance of the assembled fan rotor will be better." ”

Li Tianfeng often comes to the assembly workshop, and many workers and masters Li Tianfeng know, this worker master who is assembling the fan rotor, Li Tianfeng just remembers that this master is surnamed Lu. He is a master with rich assembly experience.

Hearing this, Master Lu took the fan blade weight table and looked at it carefully, and even took out a paper, pen and calculator to calculate, and then said: "Mr. Li, really, change the assembly position like this." The mass distribution of the fan rotor is more uniform. ”

Li Tianfeng nodded, then looked at other parts, and even looked at the assembly process, and after not finding any problems, Li Tianfeng was ready to leave, ready to go to other assembly stations to have a look.

Li Tianfeng reminded: "Master Lu, this is our first prototype, and we must ensure the quality of assembly." ”

Master Lu said: "Mr. Li, don't worry. In terms of quality, we must strive for perfection and strictly ensure the quality of assembly. ”

"Hmm." Li Tianfeng nodded, and then walked to another component assembly station not far away, which was the assembly area for combustion chamber parts.

Li Tianfeng stood next to the assembly workbench of this assembly station, and looked roughly, but did not see the flame cylinder, only the combustion chamber casing, and some other accessories of the combustion chamber part.

Li Tianfeng knew. The flame canister is still being verified, and it may take another ten days and a half months to complete the full verification. Because of the flame barrel design of this engine, Li Tianfeng has made small design improvements and improvements.

The aim of this design improvement is to achieve more adequate fuel combustion, higher fuel efficiency and lower emissions.

Fortunately, another major part of the combustion part, the combustion chamber casing, has been successfully trial-produced. Good quality, assembly is now underway.

The structure of the combustion chamber casing superalloy sheet metal weldment is also extremely complex, but the scale design is carried out on the basis of the turbofan 16 engine, and the structure is similar to the combustion chamber casing of the turbofan 16 engine. It's just that the size is more than one size smaller.

Because the scale design is completely carried out, the structure has not been changed, so the trial production and verification of the parts are relatively smooth, because in the trial production of the turbofan 16 engine, such a combustion chamber casing has undergone sufficient process verification, design verification, and material verification.

Li Tianfeng stood next to the assembly workbench and carefully watched the assembly workers assemble the combustion chamber casing. On the casing of the combustion chamber, a lot of spare parts will be installed, and Li Tianfeng couldn't help but nod when he saw that the assembly workers were assembling more seriously.

"Mr. Li, hello!" A surprised voice sounded in Li Tianfeng's ears, Li Tianfeng looked up and recognized that this was a technician in the assembly workshop, and couldn't help but nod.

Li Tianfeng said: "Meng Gong, are you following the scene?" ”

The technician said: "Mr. Li, the first prototype of our 'TFWS003' turbofan engine has entered the assembly of components, and I will take a look at the assembly site." ”

Li Tianfeng nodded, and also saw several process technicians not far away, these technicians were tracking the assembly situation on the spot, and by the way, they also guided the workers to assemble and check the assembly quality.

Next to the assembly station of combustion chamber parts, Li Tianfeng looked at it for a long time, and saw that there were basically no technical problems, Li Tianfeng was more relieved, and then walked to another assembly station not far away.

On the assembly workbench of this assembly station, there are a lot of bearings, including several main bearings of the engine, Li Tianfeng naturally knows, these bearings are all bearings of the "TFWS003" type turbofan engine.

Li Tianfeng picked up one of the bearings with great interest, looked at it with great interest, and then, Li Tianfeng nodded, thinking in his heart, the quality of Linhai Technology's bearings has been slightly improved, such bearings are completely the top aviation bearings.

Seeing these bearings, Li Tianfeng couldn't help but think of the good news call from Zhao Linhai a few days ago.

On the phone, Zhao Linhai told Li Tianfeng that the total sales of Linhai Technology are expected to exceed 10 billion yuan this year, and all kinds of aviation bearings produced by Linhai Technology Company have successfully entered major domestic aviation industry enterprises.

Even, Zhao Linhai happily told Li Tianfeng that several giants in the world's aviation industry have expressed strong interest and are ready to purchase aviation bearings produced by Linhai Technology Company.

However, Li Tianfeng clearly told Zhao Linhai that he would not sell his bearings to the world's aviation industry giants for the time being, and in addition, Li Tianfeng told Zhao Linhai that he could fully enter the automobile, shipbuilding, military and other industries.

There is high-quality quality in hand, it is natural to further expand, especially in the automobile, shipbuilding, military and other industries, as for the aviation industry, domestic aviation industry enterprises can provide this top aviation bearing, as for export, there is no need for the time being.

After Li Tianfeng looked at these bearings, he was very satisfied, put down the bearings, and turned around in the assembly workshop.

After processing the documents on his desk, he was about to take a sip of tea, when Xu Lilong's phone called, and Li Tianfeng couldn't help but smile slightly.

According to Li Tianfeng's request, a few days ago, Xu Lilong personally led a team to Bombardier in Canada, and Sun Xiaoping also went over together, mainly because Sun Xiaoping understands technology, and Sun Ping can answer some technical things.

Xu Lilong and his entourage of seven people can be regarded as a large lineup, and the purpose of going to Bombardier in Canada is naturally to sell their own engines.

Xu Lilong said on the phone: "Boss, I just had a long negotiation with the person in charge of Bombardier Aerospace, and there was a little progress. ”

Bombardier Aerospace is a subsidiary of Bombardier Inc. It is the world's third-largest aircraft manufacturer by number of employees (after Boeing and Airbus) and the world's fourth-largest commercial aircraft manufacturer by annual shipments (after Boeing, Airbus and Embraer).

There is a little progress that is not bad, listening to Li Tianfeng felt more happy, Li Tianfeng said: "Mr. Xu, you tell me in detail." ”

Xu Lilong seemed to be more happy, and said happily: "Boss, Bombardier Aerospace said that it is willing to try our engine, and promised to install our turbofan 17 engine on their aircraft for testing, and also promised to install our 'TFWS003' turbofan engine on their aircraft for test flight after the successful trial production." ”

This is really a lot of progress, compared to the last contact with Bombardier, this time the progress is very obvious, at least, the other party agreed to try their own engine.

Perhaps, this will be the best breakthrough to form a comprehensive cooperation with Bombardier, Li Tianfeng is still more confident in his own engine.

Li Tianfeng said happily: "Mr. Xu, we have finally taken a solid step, as long as the other party is willing to try our engine, it will be a great thing for us." ”

Xu Lilong also said: "Yes, boss, after they fully understand our engine, they will definitely take a fancy to our engine." ”

After thinking about it, Xu Lilong said: "Boss, after my understanding, Bombardier may already know that Embraer is using our engines, so it has the intention of trying out our engines." ”

Li Tianfeng smiled, Li Tianfeng knew that in the international regional airliner market, Bombardier and Embraer were in competition, and their competitors were using Tianfeng Technology's engines, and Bombardier would definitely not be able to sit still, so he agreed to give it a try.

Li Tianfeng was very happy, so Li Tianfeng said: "Mr. Xu, it is difficult for everyone to go abroad once, and take everyone to have a good time in Canada for two days, so that everyone can relax and relax." ”

Xu Lilong said: "Boss, then I will thank you on behalf of everyone, and we will come back in two days." ”

After talking to Xu Lilong on the phone, Li Tianfeng thought in his heart, this is good, and he will soon knock on the door of Bombardier.
