Tianfeng Technology Company.

In the office, Li Tianfeng was looking at the military's official reply to himself, the design and technical outline of the RQ2000 engine, the military has officially reviewed and passed, and he is very satisfied with this outline, and the review has been very smooth.

As soon as he read the official reply from the military, Sun Xiaoping knocked on the door and came in, Sun Xiaoping reported: "Boss, I just went to the processing site to take a turn, and our trial production of turbofan 20 engine parts and turbofan 16B engine parts is very good." ”

Li Tianfeng nodded, during this period of time, Li Tianfeng basically went to the processing site every day to have a look, and he also had a better understanding of the situation, and Li Tianfeng was also satisfied with the trial production and processing of various parts.

Li Tianfeng said: "Mr. Sun, you came just in time, this is the official reply of the military, we designed this power for the Type 99 main battle tank, its design technical outline has been successfully passed, and a comprehensive design can be carried out on this basis." ”

Sun Xiaoping took this official reply from the military from Li Tianfeng, looked at it carefully and said: "Boss, the military has a high opinion of our design technical outline, and in addition, the military has temporarily named this engine RQ2000 engine." ”

"Hmm." Li Tianfeng said: "Mr. Sun, you should hurry up and carry out a comprehensive design on this basis." ”

Sun Xiaoping said: "Boss, don't worry, we will organize the design work immediately, it's just...."

Seeing that Sun Xiaoping was hesitant, Li Tianfeng immediately understood what was going on, Li Tianfeng smiled and said: "Our RQ2000 engine, its combustion chamber technology is very advanced, the design of the combustion chamber, I will personally take the lead, the overall design of the combustion chamber, the relevant main components." and detailed design parameters, all of which I do myself. ”

Sun Xiaoping said: "Boss, you design it yourself, the workload is too large, just give important design parameters and design schematics of important parts." ”

Li Tianfeng thought for a moment. Then he said: "It's okay, but in this way, it will be a huge test for you, this is the latest and most advanced combustion chamber design, looking at the world, this combustion chamber design is also very leading." ”

Sun Xiaoping said: "Boss, it is a challenge and test for us. It's more of a workout and improvement, and I love the challenge. ”

Li Tianfeng nodded with satisfaction, and then said: "Okay, this kind of combustion chamber design, we will first verify it on the RQ2000 engine, and later, if we design a new turbofan engine, such a combustion chamber technology will be mature." It can be used on this new engine. ”

Sun Xiaoping had already guessed in his heart that Li Tianfeng adopted such an advanced combustion chamber design. It must be to lay the foundation for a new, more advanced aero engine design in the future, so Sun Xiaoping nodded approvingly.

The RQ2000 design technical outline was officially approved by the military, led by Sun Xiaoping and Qiu Wenan, who served as the chief and deputy chief designers of this engine. Full-scale design work began.

Li Tianfeng also seized all the spare time to draw the design sketches of the combustion chamber by himself, give the design parameters, and after these design sketches were completed, he handed them over to Sun Xiaoping and Qiu Wenan to carry out the design ......

Canada. Bombardier Inc.

At the test site, a Bombardier regional airliner landed on the runway, taxied, slowed down, and then stopped.

The plane came to a standstill, and many engineers and technicians trotted all the way to the plane, the engine of the plane was two turbofan 18 engines, these two starts, and so far, a series of verification test flights have been completed.

Just now is the last subject of the test flight verification, this last test flight verification, seems to be very good, no, a lot of Bombardier engineering and technical personnel, as well as Peng Jiangtao and other Tianfeng Technology company technicians, everyone ran to the plane together, a series of detailed inspections.

After some inspection, various inspection data were summarized, and a big foreigner gave a thumbs up to Peng Jiangtao, "Peng, it's great, all the performance parameters and data are fully qualified, very beautiful, great." ”

"Yes, super!" Next to him, another Bombardier technician agreed.

Peng Jiangtao breathed a long sigh of relief, and the two engines finally completed a series of verification test flights smoothly and perfectly in accordance with Bombardier's requirements.

Distance.

Several middle and senior Bombardier executives were present at the scene, where they were watching the aircraft with great interest, waiting for the final flight test data.

The tall man just now came outside, and after giving Peng Jiangtao a thumbs up, he walked in front of the middle and senior managers with a happy face and reported the test flight.

Although it was a little far away, Peng Jiangtao could still vaguely see that the faces of the middle and senior managers of Bombardier were full of smiles and looked very good.

Peng Jiangtao's side, several of Peng Jiangtao's subordinates glanced at each other, everyone's faces were full of joy, and one of them said: "Head, our engine test flight performance is perfect, and we finally successfully completed a series of test flight tasks." ”

Peng Jiangtao said: "After the whole test flight process, everyone performed well, and I will report to the company's senior management truthfully and strive to reward everyone." ”

Hearing this, everyone's faces were even more happy.

Peng Jiangtao looked at the time and thought in his heart that he must report this good news to the company.

Clear stone manufacturing base.

Li Tianfeng is checking the entire manufacturing base with Zhang Can, Hu Donghai, He Baitao, etc., and the relocation work took about a week, and a week later, the production began to start, and the entire manufacturing base gradually got on the right track.

We walked into one of the large buildings, which is a specialized shaft parts production line, and we can see that various shaft parts for turboshaft D and turboshaft E engines are being manufactured here.

Small shaft parts, but the thickness of chopsticks, the diameter of the large is 20 or 30 millimeters, the short ones are only a few tens of millimeters, and the long ones are hundreds of millimeters.

Among them, the longest is the elastic shaft of the turboshaft D engine, with a length of 1020 mm, a maximum diameter of 22.5 mm, hollow, and a high-temperature alloy.

We walked to a deep hole drilling machine, and happened to see a batch of elastic shafts in deep hole processing, the blank of the elastic shaft is a solid bar, to be processed into a hollow, it is necessary to drill holes in the middle.

You can imagine the long barrel drilling, which is basically the same, but the process method is a little different, and the difficulty and precision are much higher.

Seeing this batch of parts being processed, Li Tianfeng said: "Mr. Zhang, the processing of elastic shafts, at the beginning of engine development, when the parts processing technology was verified, I remember that seven batches of parts were processed, and seven batches of parts were trial-produced, and finally a more reasonable process method and parameters were obtained. ”

Recalling the trial production of the elastic shaft, Zhang Can was also very touched, Zhang Can said: "Boss, you still remember so clearly, this is a difficult bone to gnaw at the beginning, the elastic shaft is not only an important and key part, but also complex structure, high precision requirements, processing batch after batch of parts, the process specification has been improved and improved over and over again." ”

The elastic shaft not only has high precision requirements, but also has high-precision splines, bearing mounting journals, straightness requirements and runout requirements of the elastic shaft on the shaft.

Li Tianfeng said: "However, now it's good, the process is mature and stable, and the quality of the parts is also very good." ”

After speaking, Li Tianfeng also personally picked up an elastic shaft, looked at it with great interest, and then nodded with satisfaction.

Zhang Can said: "The processing technology of each part of the vortex D and vortex E has been very mature, the product quality is very stable, and our monthly output has been stable at about 70 or 80 units. ”

Li Tianfeng said: "Qingshi manufacturing base, the design capacity of the first phase of the project is 100 turboshaft engines, and when your personnel are replenished, there will be no problem with a monthly output of 100 units, and if the second phase of the project is also completed, the production capacity will be doubled." ”

Zhang Can and others were slightly excited in their hearts, the second phase of the project was put into use, with a monthly output of 200 turboshaft engines, what a sense of accomplishment this is a figure.

Li Tianfeng said: "Mr. Zhang, our Qingshi manufacturing base, in the future, will not only produce and manufacture turboshaft D and turboshaft E engines, but also produce various types of military gas turbine engines, such as tanks and armored vehicles. ”

"It may not be enough, we may develop and produce large gas turbine engines in the future, such as marine gas turbine engines."

Zhang Can said: "Boss, no wonder next to the Qingshi manufacturing base, that hundreds of acres of vacant land, have been bought by our company, it turns out that our Qingshi manufacturing base has three phases of the project, and will also produce and manufacture various types of gas turbine engines." ”

Li Tianfeng nodded, and Li Tianfeng said: "Zhang Can, in your heart, what will Tianfeng Technology Company look like in the future?" ”

Zhang Can thought for a while and said: "In the future, Tianfeng Technology Company will be a world-class aviation industry enterprise, and it will have many types of engines. ”

Li Tianfeng said slowly: "This is not enough, my plan is that after our efforts, in a few years, Tianfeng Technology Company will be a worldwide aviation industry giant, a veritable aviation industry overlord, with the world's most advanced aero engines, research and development and manufacturing of the world's most advanced aircraft." ”

Overlord of the aviation industry!

Zhang Can and the others glanced at each other, and the passion in their hearts was ignited at once, everyone quietly clenched their fists, and said in their hearts, yes, we must become the overlord of the aviation industry, and work hard, work hard, and work hard for this goal!!
