The work of sending materials obviously does not need to be done by people at the level of chief engineers like Huang Haixing and Mei Yishu.

In fact, the main purpose of Shangfei's visit to Tiancheng this time is to inspect the processing capacity of Zhengxin Group's industrial base. After all, no matter how dissatisfied Li Fanyu is, Zhengxin Group has the ability to manufacture cutting-edge parts that can only be manufactured by developed industrial countries in Europe and the United States, which in itself is a kind of ability to attract Shangfei Company.

Before they had time to visit the industrial base, everyone learned that Li Fanyu and others were testing for Hangfa. Mei Yishu and Huang Haixing were suddenly shocked!

"How is that possible? How long has it been for them to come up with a flight start?"

"Liar, isn't it? If it's not for us to be funny, then Zhengxin must have been involved in the field of aviation development a long time ago!"

"It doesn't make sense! Zhengxin has only been established for a few years? The technological explosion of the entire group, that is, the matter of the past two years, a few years ago, they were even short of manpower in their own engine research and development, how could they put their energy into burning money and costly aviation engines? Impossible, impossible!

Facing the gossip of the superior R&D engineers and the leaders of the Shangfei inspection around him, Huang Haixing coughed lightly, suppressed the atmosphere slightly, and asked Dimon who came to invite: "Since this is the case, then please take us over." ”

Dimon nodded, although he was not very happy with the resistance and sourness shown by these people's words, he still politely invited people into the car and took them to the R&D center where the power laboratory was located.

At this time, the Tianxing I-1 had already made all the preparations on the bench, and the engineers were manually pushing the turbine fan blades to perform the first cold start to lubricate the interior.

When Huang Haixingmei and his entourage of Shangfei Company came to the power laboratory, the moment they saw Tianxing I-1, a snickering sounded in the power laboratory.

"Wow, I thought a miracle had really happened, and I made a real voyage in such a short period of time, and I felt ...... It's just to make a model airplane engine and come out!"

"Who says it's not? This can also be called aviation development? How big of an aircraft can this drive? I'm afraid that our C9 needs to be reduced by a hundred times in order to apply such power. It's just hilarious to take out、"

"Li Dong is really humorous, he made a pocket engine model and came out for a test drive, but the cowhide was blowing loudly, and he also tested it, I think ...... It's just a test machine, right?"

It's no wonder that everyone laughed when they saw the Tianxing I-1, compared to the supporting engine of the C9 project, the Tianxing I is too small.

The C9's AJ919 engine is the size of a pickup truck, with a net length of 6.2 meters without a casing, and the diameter of the fan turbine alone is nearly two meters. What about Tianxing I? Now on the bench, the total length of the part of the combustion chamber shell is only 1.2 meters, and the diameter is only 45 centimeters.

Although it is a bit cold to say that it is a model aircraft engine, it is not an exaggeration to describe such an aviation engine as a toy in the professional field. In fact, such aviation development is also in the current aviation development manufacturing field, but it is mostly used in the famous Williams company. It is specialized in small turbojet, gas turbine aero engines. Most of these small aircraft launches are used for tactical missiles, target aircraft and unmanned aerial vehicles.

Seeing the size of Tianxing I-1, Huang Haixing smiled and shook his head. The huge doubts that had existed in my heart before were slightly relieved.

With the increase of thrust and thrust-to-weight ratio, the processing technology and cooling technical difficulty required by Hangfa are increasing geometrically. This little thing in front of him seems to be some kind of experiment, if Shangfei wants to do it, it can be completely designed in a short time.

When he heard that Zhengxin had made research achievements in the field of aviation development, Huang Haixing was secretly surprised, but now, he felt that Zhengxin was a little cute-innocent and cute.

With this thing, you dare to say that you have made achievements in the field of aviation development, isn't it like a seven-year-old child waving a tree branch and saying that he has obtained a peerless sword?

"Hehe, Li Dong, don't come unharmed?"

Just as he was looking at Tianxing I in the distance, he secretly shook his head, and Li Fanyu, who was wearing a one-piece denim overalls printed with "Zhengxin Xcar", walked over.

"Dong Li, don't come to harm?"

Huang Haixing quickly retracted his thoughts and said hello with a smile.

Unexpectedly, Li Fanyu ignored him, and came directly to Mei Yishu, "Yo, isn't this Mei Lao? Mei Lao, you are not kind." I've been stepping on me so hard these days, I don't remember reporting that your grandson jumped into a dry well!"

Although Li Fanyu doesn't care much about what the outside world says, he is not a particularly broad-minded person - he still remembers the account!

Who is Mei Yishu?

In the field, it is a master, and it has a certain status in the Chinese academic community!

Except for the students who are all over the world, as well as the selfless help of firefighters, in terms of the number of patents in their hands alone, Han Yiming and Mei Yishu are actually not much different.

Of course, this has something to do with the fact that Han Yiming never cares about these patents, and often gives away the patents to which he has made major contributions-just like when he gave all the intellectual property rights of the caterpillar suspension to Zhengxin in vain.

Therefore, even though Li Fanyu's status is quite high, talking to Mei Yishu like this still touched the nerves of many people present.

"Li Fanyu, isn't what you said a little inappropriate?"

"What's wrong? I'm just asking!" Li Fanyu quickly responded, "Look, I didn't find someone I didn't provoke, I provoked a foaming star, and now that I met the main master, you won't let me ask?"

Seeing that Li Fanyu didn't give face at all, Mei Yishu's students immediately stood up to escort him.

"What kind of attitude do you have? What is wrong with what Mei Lao said? Even if there is something wrong with what Mei Lao said, what is your identity, what is Mei Lao's identity? How old are you, how old is Mei Lao? Besides, now I think Mei Lao is right! You are saying that you have made a breakthrough in the field of aviation development, and now you will come up with such a game? Where are you thinking that the C9 is a missile target aircraft? What can such an engine do? I am afraid that it will take three or four business planes to push a business plane with a load of more than ten people, right?"

Li Fanyu is not convinced!

"Oh, dare to love when you're old, you can fire guns indiscriminately? I don't want to lose face when I'm young? If you want to respect, you must at least respect me first! Also, what is 'such a play'? Although the scale is small, it can weigh a thousand pounds! Haven't you heard of it?"

"You!"

The person who just spoke was choked by Li Fan's stupidity.

"Enough!" As a party concerned, Mei Yishu was ten thousand unhappy in his heart. But he also knows that spitting with Li Fanyu, who has a bad reputation in the academic world, even if he wins, it will not be good for him.

"Li Fanyu, aren't you here to let us see the test car? When will it start?" Mei Yishu's color was a little gloomy.

At this moment, the announcement in the power laboratory sounded: "Cold start lubrication completed, fuel filled, start, test run! Please leave the bench, countdown ......"

As the countdown sound ended, an excited buzz suddenly sounded in the power laboratory!
