After carefully looking at the design of the gas turbine disk, Li Tianfeng picked up the phone, "Mr. Qiu, come to me." ”

Soon, Qiu Wenan came over, "Boss, it's about the design of our gas plate." ”

Li Tianfeng nodded.

Qiu Wenan was slightly excited, "Boss, I have adopted a lot of new designs to ignite the turbine disk, which is a precedent in China, such as the design structure of the double-width plate, and the welded integral blade disc design of the blade and turbine disk, which are in the forefront of China." ”

The gas turbine of the "TFWZ001" turboshaft engine belongs to the high-load turbine, and the diameter of such a small turbine disc is more than 100 millimeters, and it is necessary to output huge and powerful power, so you can imagine the load of this small turbine disk.

The turbine disc adopts powder metallurgy superalloy, which is a relatively new superalloy material in China, and it is also the current trend of turbine disc materials.

The turbine blade material is more advanced, single crystal superalloy blade, turbine blade design, Li Tianfeng has provided a design sketch, Qiu Wen'an and others are grasping the design, the design of turbine blades, the difficulty is relatively large, not only the blade type is more advanced and complex, or vacuum blades, there are many cooling pores, in addition, there is a thermal barrier coating on the blade.

As a key component of aviation gas turbine engine, turbine plays a pivotal role in its development system, and its key technologies mainly involve blade design and optimization, blade cooling and heat transfer, and turbine and engine compression system matching.

Whether it is the design of the turbine disc or the design of the turbine blade, Li Tianfeng attaches great importance to it, personally checks it, and earnestly improves it.

The design of the turbine blades is still very advanced "ultra-cool" blades. That is, super cooling blades, on each blade, there are hundreds of small holes cast or laser-punched, and it is these small holes that play a cooling role.

The gas turbine disc adopts a hollow double-spoke plate turbine disc, which is considered to have made an innovative design in the structure, and it is the first time in China to adopt such a design concept. The spoked plate turbine disc is welded through guò, which can reduce the weight by more than 20% and increase the speed by more than 10% compared with the traditional turbine disc.

Of course, after the design of such a turbine disk is completed, relevant test work needs to be carried out, and the design work is carried out now.

At present, Qiu Wenan has a little admiration for Li Tianfeng, and he used to admire it. Now it's worship, some of Li Tianfeng's design concepts, the design level of the table, Qiu Wen'an admires it so much, and now, Qiu Wen'an sits opposite Li Tianfeng, looking humbly taught.

Just like the design of this gas turbine disc, some new design concepts. Qiu Wen'an is still the first real contact, before. At most, I just know about it, saying that I have heard of such a design. For example, the design of the hollow double-spoke plate turbine disk, Qiu Wenan only understands and hears of it.

With such an advancement, Qiu Wenan naturally consulted Li Tianfeng many times during the design process, and Li Tianfeng did not hide his personal interests. Each time, it was explained in great detail until Qiu Wen'an really understood.

Li Tianfeng nodded, opened the design drawings of the gas turbine disk, and explained to Qiu Wenan one by one very carefully. Point out some areas that need to be improved and perfected one by one.

After a long time, after all these things were finished, Li Tianfeng said: "Mr. Qiu, do you understand?" ”

Qiu Wenan hurriedly said: "Boss, I completely understand, I will immediately improve and modify the design drawings." ”

Seeing Qiu Wenan leave his office, Li Tianfeng also looked forward to it, and has basically completed the design of the key parts of the core engine of the "TFWZ001" turboshaft engine, such as the axial flow impeller and centrifugal impeller of the compressor part, the flame cylinder of the combustion chamber, the gas turbine disc of the turbine part, the free turbine disc, and only the design of the turbine blades.

The design of turbine blades is not simple, not only in the cutting-edge technology of "ultra-cool" blades, but also the use of relatively new blade design, the designer's business level is very high, in the design process, Li Tianfeng will definitely have to "guide" everyone.

The whole "TFWZ001" turboshaft engine adopts a lot of new designs, and the overall performance should not be bad, Li Tianfeng is looking forward to speeding up the research and development progress and developing the first engine as soon as possible.

My first engine!

It's exciting enough to think about it, and it is still a turbine shaft engine that represents the top level in China, which is simply too exciting and exciting.

"When the 'TFWZ001' turboshaft engine is really developed, I don't know what kind of response the domestic aviation industry will have." Li Tianfeng thought in his heart.

"Perhaps, when the first TFWZ001' turboshaft engine was developed, it was also the time when Tianfeng Technology Company fired the first shot." Li Tianfeng thought so again in his heart.

………

"Tianfeng, where is it, why haven't you come here yet."

The call was made by Wang Ruobing, today, Wang Ruobing will return to the capital by plane, and the glorious task of sending people off will naturally be completed by Li Tianfeng, the two made an appointment, and seeing that Li Tianfeng has not yet driven over, Wang Ruobing couldn't help but call over.

When he answered the phone, Li Tianfeng was driving, and he had already arrived at the gate of the "Waterfront Spring" villa community.

The design sketch of the turbine blade has been freshly released, and some important parameters are also standard, as well as some points that need to be paid attention to, Li Tianfeng is calling Qiu Wenan, Sun Xiaoping and others to explain the design of the turbine blade one by one, so it took a little time.

Driving to the door of Wei Jin's villa, and seeing Wang Ruobing, Li Tianfeng said apologetically: "Ruobing, I'm a little late." ”

As he spoke, Li Tianfeng got out of the car, picked up Wang Ruobing's gift box, put it in the trunk of his off-road vehicle, and then invited Wang Ruobing to get in the car. Wei Jin is not at home, Wang Juan is in the company, and even Jiajia is at school, just Wang Ruobing and Li Tianfeng.

Wang Ruobing didn't blame Li Tianfeng for being late, on the contrary, Wang Ruobing smiled, because Wang Ruobing knew that Li Tianfeng had such a big company, and it was very good to be able to take the time to send him to the airport in person.

Wang Ruobing took the co-pilot's position and said with concern: "Tianfeng, I've been tired lately, don't be tired." ”

Li Tianfeng said: "It's okay, I've been busy lately, but I often exercise my body, my mental state is very good, and my body is also great." After speaking, he also exaggerated his arm muscles, seeing this, Wang Ruobing sneered, beautiful and incomprehensible.

Li Tianfeng was stunned and sighed in his heart, it's so beautiful, it's so beautiful.

Seeing Li Tianfeng's expression, Wang Ruobing smiled proudly.

Li Tianfeng also quickly came back to his senses, started the off-road vehicle, walked out of the "Waterfront Spring" community, and drove towards Huangping Airport.

While driving, Li Tianfeng chatted with Wang Ruobing, "Ruobing, after returning to school to attend the graduation ceremony, what are your plans in the future?" ”

This time back to school, Wang Ruobing attended the graduation ceremony, completed four years of university study, and was considered a formal bachelor's degree, Wang Ruobing thought about it and said: "I haven't thought about it yet, maybe it's to enter Dadi Jewelry Company to help my sister take care of business, maybe it's to continue her studies." ”

Li Tianfeng smiled jokingly and said, "How about being a housekeeper for me?" ”

Wang Ruobing smiled and said, "I won't be your housekeeper." ”

"I really don't want to, then I'll find someone else." Li Tianfeng joked.

"You dare!" Wang Ruobing's little hand twisted Li Tianfeng's waist, and his movements became more and more proficient, Li Tianfeng hurriedly begged for mercy: "It hurts, it hurts, it affects my driving." ”

Wang Ruobing let go and snorted proudly.

The two talked and laughed all the way, the off-road vehicle arrived at Huangping Airport, Li Tianfeng helped Wang Ruobing carry the suitcase and sent it all the way to the airport, and the security check was in front of them, and the two stopped.

Li Tianfeng was about to say something, when suddenly, Wang Ruobing threw himself into Li Tianfeng's arms, hugged Li Tianfeng's neck, raised his beautiful face, and said softly: "Tianfeng, kiss me!" ”

This is Wang Ruobing's first kiss, Wang Ruobing's movements are very rusty, even very shy, under the guidance of Li Tianfeng, he gradually became proficient, this kiss is at least more than a minute.

"Tianfeng, remember to call me!"

Li Tianfeng nodded, and said a little emotionally: "Well, I will call you every day, pay attention to your safety along the way, and we will contact you when you get off the plane." ”

Wang Ruobing nodded, carrying his gift box, reluctantly turning back step by step, after passing the security check, he was still looking back at Li Tianfeng, seeing this, Li Tianfeng was greatly moved.

Seeing Wang Ruobing's plane flying into the blue sky, Li Tianfeng reluctantly retracted his gaze.

Although he was favored by Wang Ruobing, Wang Ruobing even gave his first kiss, but Li Tianfeng didn't know that a huge crisis was gradually forming, and with Wang Ruobing's official graduation, this crisis gradually struck.

Of course, this is a later story, Li Tianfeng didn't know it for the time being, until one day, someone else came to the door arrogantly, and Li Tianfeng didn't know what was going on.

It wasn't until the plane flew farther and farther away, gradually becoming a small black dot, until finally it was no longer visible, Li Tiancai reluctantly withdrew his gaze and drove back to Songzhou City.

…………

drove directly back to Tianfeng Technology Company, and after processing a few documents in the office, Li Tianfeng's mobile phone rang.

Li Tianfeng thought in his heart, who called, Wang Ruobing's words were not so fast, and he should still be on the plane now, thinking so in his heart, Li Tianfeng picked up the phone and looked at it, he was slightly stunned, how could it be that he called.

………

Today's three more, the second one is sent, and the last one is in the codeword......

There are too many things today, and there are meetings in the morning and afternoon, but I thought that I had promised three more today, and I had to finish writing it after fighting my life, and I continued to code words.

……… (To be continued......)
