Tianfeng Technology Company.

Li Tianfeng was in his office, fidgeting, inexplicably irritable in his heart, Li Tianfeng said in his heart, what happened today.

Trying to calm himself down, he wanted to review a few of the design drawings sent by Qiu Wen'an, but sitting in front of the computer, Li Tianfeng felt that his brain was blank and he couldn't concentrate at all.

What's wrong???

Li Tianfeng got up and walked back and forth in his office, exactly like an ant on a hot pot.

The mobile phone rang urgently, Li Tianfeng took the mobile phone and looked at it, and saw that it was Wang Ruobing's phone, Li Tianfeng immediately connected, and there was silence on the phone, Li Tianfeng immediately shouted eagerly: "Ruobing, what's wrong, speak!" ”

There was still silence on the phone, for a long time, a faint sobbing sound came, hearing Wang Ruobing's cry, Li Tianfeng felt an inexplicable heartache, "Ruobing, what did you say?" ”

"Tianfeng, woo......" Wang Ruobing cried for a while, "Tianfeng, do you love me?" ”

Li Tianfeng thought in his heart, what happened to Ruobing, something must have happened, otherwise, he wouldn't cry, and he wouldn't ask himself if he loved her, Li Tianfeng said without hesitation: "Ruobing, I love you just like I love my own life!" ”

What made Li Tianfeng strange was that Wang Ruobing actually laughed and didn't cry anymore, "Tianfeng, just have your words." ”

Li Tianfeng said: "Ruobing, what happened, you tell me, otherwise, I will be worried." ”

Wang Ruobing said: "Tianfeng, don't worry about me. I am relieved to have the promise you just made, Tianfeng, I also love you, love you to the core. ”

Li Tianfeng was greatly moved, he didn't expect Wang Ruobing to love him so deeply, and he was greatly moved. Li Tianfeng said emotionally: "Ruobing, I love you too." ”

"Hmm." Nodding, Wang Ruobing said: "Tianfeng, I know what to do now, don't ask me what happened, no matter what happened, Tianfeng, you remember, I will always love you and will never change." ”

Since Wang Ruobing said so. Li Tianfeng secretly felt bad in his heart, something big must have happened, but he knew that he couldn't ask anything if he continued to ask, and at the same time, Li Tianfeng was moved for a while, I don't know how many wooden fish he knocked out in his previous life to get such a beautiful woman.

After the call, Li Tianfeng sat in his boss's chair. After a long aftertaste, the emotion in my heart could not be dispersed for a long time. At the same time, the same is true of that uneasiness, which cannot be dissipated for a long time, Li Tianfeng knows that something big must have happened on Wang Ruobing's side.

………

After a few days, Li Tianfeng gradually returned to normal. Devoted to his work, almost all his energy was focused on the "TFWZ001" turboshaft engine being developed.

The design of the important parts and key parts of the core machine is basically completed. Some parts have already begun to be processed, based on the core machine and platform, and began to carry out comprehensive design, such as the design of casing parts, the design of structural parts, and the design of a series of parts supporting it.

From the E factory, several forging blanks and several casting blanks have also come over in the past few days, and these parts have entered the workshops and started processing.

In terms of plant construction, the No. 3 and No. 4 plants should be completed and delivered, and the installation and commissioning of the first machine tool equipment began yesterday.

It is worth mentioning that Tianfeng Technology spent one million yuan to buy the most advanced 3D simulation and stress analysis software on the market, of course, it can spend one million yuan, it must be a genuine and currently the most advanced software.

At present, a large area of training is being carried out in the design institute, the purpose is to require everyone to be proficient in the use of this software.

In the memory of later generations, the aviation industry also uses this software, but the version is much more advanced than the current version, the current version is version 1.0, and in the time and space of later generations, this software has been updated many versions.

In the office.

In the past few days, Li Tianfeng has basically concentrated on his work, no, he is now using this software to import the designed axial flow impeller design drawings for three-dimensional simulation and stress analysis. Both axial and centrifugal impellers are important components of turboshaft engine compressor components.

The outside air is first compressed and accelerated by the axial impeller, and then enters the centrifugal impeller, and after the centrifugal impeller is compressed again, the air volume is greatly reduced, and the speed of high-pressure air also reaches subsonic speed, so that the high-speed, high-compression ratio air enters the combustion chamber or enters the flow channel.

The axial flow impeller is very important, and it is also a high-speed rotating part, with an ultra-high speed of tens of thousands of revolutions per minute, and the design should not only consider its air compression ratio, but also consider its force.

After Li Tianfeng imported the design drawing of the axial flow impeller, the three-dimensional graphics of the axial flow impeller appeared on the software of the computer screen, which was very beautiful.

In terms of design, the axial flow impeller adopts a new blade design, which has a high efficiency, a total of two stages of axial flow impeller, and the efficiency is higher than the three-stage axial flow impeller of the turboshaft C engine of the E factory, at least more than 50%.

He looked at the three-dimensional graphics of the axial flow impeller with satisfaction, and even Li Tianfeng rotated it at multiple angles and looked at it from different angles for a long time.

The software is more advanced, can be simulated, Li Tianfeng began the first step on the simulation operation, imitating the axial impeller in the working state, with the simulation operation, the axial impeller began to rotate, and accelerated, the speed is getting faster and faster, soon reached the rated speed of 45000 rpm, the simulated air, like tiny particles, is quickly inhaled, and then compressed, and then from the exhaust side of the axial impeller out at high speed.

Simulated, Li Tianfeng nodded slightly, the design of these two-stage axial flow impellers is basically good, and it is not in vain to spend his own thoughts, and then, simulate the force of the working state.

Analyze the force situation!

With the operation of the software, the axial impeller changes color all over, and the axial impeller, which was originally bright silver, immediately becomes colorful, with green as the main color, as well as yellow, and even red.

The darker the color, the greater the force, the green part is the least stressed, the yellow part is more stressed, the red part is the most stressed, and the redder the part, the greater the force.

The red area is basically concentrated in the blade root of the axial flow impeller, which is the stress concentration area, Li Tianfeng looked at it carefully, and used the software to carry out a force analysis calculation.

The design of the blade root should be slightly modified!

In order to improve the service life of the axial flow impeller, it is necessary to modify the design of the blade root, how to modify, Li Tianfeng knows in his heart, it is a small modification, and it will not hurt the muscles and bones.

The software is good, this million is worth it!

Originally, the usage fee of this software was more than one million, and the other party's offer was six million, but who was Li Tianfeng, since he had paid attention to this software in his heart, he was naturally prepared, and as soon as he communicated with the technical director of the other party, he said a few ideas, and the other party was immediately surprised, took the initiative to reduce the price, and even asked hard, almost humbly asking for advice.

………

No. 1 processing workshop.

The centrifugal impeller of the "TFWZ001" turboshaft engine has begun to rough mill the blades, and the axial flow impeller has also begun to be processed, of course, the axial flow impeller is processed according to the modified design drawing.

The blank of the axial flow impeller is also a forging blank, a titanium alloy forging, which has been rough-turned, and the first step of axial-flow impeller processing is rough turning, a total of several rough turning, and then the rough milling of the blade.

Li Tianfeng paid more attention to the processing of these parts, and went to the processing workshop to take a look, and saw that the processing was normal, and he was a little relieved.

After looking at the No. 1 workshop, and then returning to his office with confidence, Li Tianfeng sat down, turned on the computer, and read a few design drawings as usual, not knowing that something big had happened outside.

On Songzhou Avenue, a red sports car was roaring rapidly, and many drivers were startled and almost had a car accident.

The driver was a young man, dressed in a famous brand, with a big black mole on his cheek that was very conspicuous, while driving, he was still holding a cigarette, and in the co-pilot seat, there was a young girl dressed in fancy clothes.

The red sports car roared all the way, and then rushed into Tianfeng Technology Company, and the security guards at the gate reported that the speed was very fast, but even so, the car still rushed in at high speed, and a sharp brake stopped in front of the Tianfeng Technology office building.

This stance!

Many security guards were taken aback and chased after them all the way, and even some security guards held rubber sticks in their hands, thinking to themselves, who is this? It's too bold, it's just no one in sight!

Coincidentally, Cai Bin, the general manager of the security department, was also at the gate, and when he saw this scene, he was furious in his heart, Nima's, who is this, so arrogant, he just doesn't want to live, thinking so in his heart, where did Cai Bin dare to have the slightest slackness and hesitation, he immediately rushed out and chased the two red sports cars.

Seeing the sports car stop in front of the company's office building, Cai Bin sped up his pace, chased after him with a group of security guards, and surrounded the red sports car from afar.

The red sports car came to a stop, the doors opened, and a young man got out of it.
