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

Soon, Qiu Wen'an came over, "Boss, it's a design drawing about our gas plate."

Li Tianfeng clicked a little.

Qiu Wen'an seemed a little excited, "Boss, I have adopted a lot of new designs for ignition of the turbo disc, which is a precedent in China. For example, the design structure of the double-size plate, the welded overall blade disc design of the blades and the turbine disc, are all at the forefront of the country."

The gas turbine of the "tfwz001" type turbine shaft engine is a high-load turbine. Such a small turbine disc has a diameter of only more than 100 millimeters. It needs to output huge strong power. You can imagine the load status of this small turbine disc.

Turbine discs use powder metallurgical high-temperature alloys, which is considered a relatively new high-temperature alloy material in China and is also the current trend of turbine disc materials.

The materials of turbine blades appear to be relatively advanced. Li Tianfeng has provided design sketches for single crystal high-temperature alloy blades and turbine blade designs. Qiu Wen'an and others are working hard to design. The design of turbine blades is relatively difficult. Not only is the leaf shape more advanced and complex, but it is also a vacuum blade with many cooling pores. In addition, there is a thermal barrier coating on the blades.

As a key component of an aviation gas turbine engine, turbine occupies an important position in its development system. Its key technologies mainly involve blade design and optimization, blade cooling and heat transfer, matching of turbine and engine compression systems, etc.

Whether it is the turbine disk design or the turbine blade design, Li Tianfeng attaches great importance to it, personally checks and makes careful improvements.

The design of turbine blades still uses the currently very advanced "super-cooled" blades. That is, super-cooled blades. On each blade, there are hundreds of cast or laser-made small holes, and these small holes are used to cool.

The gas turbine disc adopts a hollow double-spoke turbine disc, which is an innovative design in terms of structure. This design concept is the first time in China. The spoke turbine disc is made of welding. Compared with traditional turbine discs, it can reduce weight by more than 20% and increase speed by more than 10%.

Of course, after completing the design of such a turbine disk, relevant test work must be carried out, and what is now carried out is the design work.

At present, Qiu Wen'an admires Li Tianfeng a little bit, and used to admire him. Now he admires him. Some of Li Tianfeng's design concepts and the design level shown by Qiu Wen'an is impressed. Now, Qiu Wen'an is sitting opposite Li Tianfeng, looking humbly taught.

Just like the design of this gas turbine disc, some brand new design concepts. It was the first time that Qiu Wen'an had really come into contact with it. At most, he only understood it. He said that he had heard of such a design. For example, the design of a hollow double-spoke plate turbine disc, Qiu Wen'an only understood it and heard of it.

With such advancedness, Qiu Wen'an naturally asked Li Tianfeng many times during the design process, and Li Tianfeng did not hide his own personal information. He explained it in great detail every time until Qiu Wen'an truly understood it.

Li Tianfeng nodded, opened the design drawings of the gas turbine disk, and explained it to Qiu Wen'an one by one, very carefully. He pointed out some areas that needed improvement and improvement one by one.

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

Qiu Wen'an hurriedly said, "Boss, I understand completely. I will immediately improve and modify the design drawings."

Watching Qiu Wen'an leave his office, Li Tianfeng also looked forward to it. At present, the design of key parts of the core engine of the "tfwz001" type turbine shaft engine has been basically completed, such as the axial flow impeller of the compressor part, the centrifugal impeller, the flame cylinder of the combustion chamber, the gas turbine disc of the turbine part, the free turbine disc, and the design of the turbine blades is only apart.

The design of turbine blades is not simple. Not only is it a "ultra-cold" blade in cutting-edge technology, but it also adopts a relatively new leaf-shaped design, which requires very high professional level of designers. During the design process, Li Tianfeng will definitely "guid" everyone again.

The entire "tfwz001" type turboshaft engine adopts a lot of new designs, and the overall performance should not be bad. Li Tianfeng looks forward to speeding up the R&D progress and developing the first engine as soon as possible.

My first engine!

It’s exciting to think about it, and it’s a turboshaft engine that represents the top level in China. This is simply too exciting and so exciting.

"When the 'tfwz001' type turboshaft engine was actually developed, I don't know what kind of response the domestic aviation industry will have." Li Tianfeng thought in his heart.

"Maybe, when the first tfwz001' type turboshaft engine was developed, it was also the time when Tianfeng Technology Company fired its first shot." Li Tianfeng thought in his heart again.

………

"Where is Tianfeng? Why haven't you come here yet?"

The phone call was Wang Ruobing. Today, Wang Ruobing will fly back to the capital. The glorious task of sending people is naturally completed by Li Tianfeng. The two made an appointment. Seeing that Li Tianfeng had not yet driven over, Wang Ruobing couldn't help calling the phone.

When answering the phone, Li Tianfeng was driving and had reached the entrance of the villa community of "Shuian Spring". He was in the company just now, and some important things were delayed. Li Tianfeng was a little late.

The design sketch of the turbine blades has been freshly released, and some important parameters are also standardized, as well as some points that need attention. Li Tianfeng was summoning Qiu Wen'an, Sun Xiaoping and others to explain the design of the turbine blades one by one, so it took a little time.

When he drove to the door of Wei Jin's villa, he saw Wang Ruobing, and Li Tianfeng said apologetically: "Ruobing, it's a little late."

As he said that, 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 on the car. Wei Jin was not at home, Wang Juan was in the company, and even Jiajia was in school, just Wang Ruobing and Li Tianfeng.

Wang Ruobing did not 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 already very good to take the time to send him to the airport in person.

Wang Ruobing got into the co-pilot's position and said with concern: "Tianfeng, you're tired recently, don't get tired of your body."

Li Tianfeng said: "It's okay. I'm really busy lately, but I often exercise, have a good mental state, and are in a good health." After saying that, he exaggeratedly showed his arm muscles. Seeing this, Wang Ruobing laughed, and was so beautiful.

Li Tianfeng was stunned and sighed in his heart, "It's so beautiful, 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, left the "Shuiban 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, Wang Ruobing attended the graduation ceremony and completed four years of college study. He was considered to have officially graduated from undergraduate studies. After thinking about it, Wang Ruobing said, "I haven't thought about it yet. Maybe I'm going to join Dadi Jewelry Company to help my sister manage the business, or maybe I'm continuing to study."

Li Tianfeng smiled jokingly and said, "How about you be the housekeeper for me?"

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

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

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

Wang Ruobing let go and snorted proudly.

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

Li Tianfeng was about to say something, but 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 was Wang Ruobing's first kiss. Wang Ruobing's actions were very unfamiliar and even shy. Under the guidance of Li Tianfeng, he gradually became proficient. This kiss lasted for at least one minute.

"Tianfeng, remember to call me!"

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

Wang Ruobing nodded, carried his gift box, and turned around reluctantly. After passing the security check, he was still looking back at Li Tianfeng. Seeing this, Li Tianfeng was very moved.

Only after watching the plane Wang Ruobing flew into the blue sky, Li Tianfeng reluctantly withdrew his gaze.

Although he was favored by Wang Ruobing and Wang Ruobing even gave him his first kiss, Li Tianfeng didn't know that a huge crisis was gradually forming. As Wang Ruobing officially graduated, the crisis gradually came.

Of course, this is a story later. Li Tianfeng doesn't know yet. It was not until one day when someone came to the door arrogantly that Li Tianfeng knew what happened.

Until the plane flew farther and gradually became a small black dot, until it was finally impossible to see it again, Li Tiancai reluctantly retracted his gaze and drove back to Songzhou City.

…………

He drove back to Tianfeng Technology Company directly and processed several documents in the office, and Li Tianfeng's cell phone rang.

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