When the time moved forward to July, the construction of the Chengnan base had been basically completed. Each factory building was reasonably and scientifically arranged, and the straight factory road was almost impossible to see at a glance.

The distance between each factory building is very large, the roads in the factory are very spacious, and the roads in the factory are common with eight lanes or even ten lanes. This is mainly to consider the transportation of large components.

Especially the assembly factory, which is wide all around and the factory gate is very spacious. If the door is opened, even a giant like the Airbus a380 can easily enter and exit.

Here, it is a model of modern factories, decorated with flowers, plants and trees, a garden-style factory, and a huge factory.

Two huge assembly factories have been completely topped off and have entered the installation and construction of the factory, while the other factories are completely in full swing.

Now, at the Chengnan base, not only are Bombardier, but also Embraer, and even COMAC are preparing to come to make parts of Hercules material for their passenger planes.

The weather in July is already very hot, while the factory is very cool and comfortable. Each factory has an advanced central air conditioning system. The temperature in the factory is kept at around 20 degrees all year round.

The design of the "Black Ghost" drone has not been completed yet, but the trial production of some parts has been started, and most of them are structural parts.

The structural design of the "Black Ghost" drone has been completed, and all structural parts have been basically finalized. With Li Tianfeng's order, these structural parts have entered the trial production stage.

The trial production of structural parts not only requires verification of the manufacturing process, but also requires stress performance tests, fatigue tests, etc.

Li Tianfeng, Zeng Qinghai, Lei Yong and others were looking at the processing of structural parts in a workshop. Li Tianfeng picked up a structural part called "wall panel" and looked at it carefully.

This part is made of Hercules material. The parts seem to be relatively large, but the weight is relatively light, so Li Tianfeng can easily pick it up with one hand.

After looking at it, Li Tianfeng said to Zeng Qinghai next to him: "Mr. Zeng, the parts are processed well, look at it. How beautiful the threaded holes on this part are processed."

Next to it is an imported three-coordinate CNC machining center that is processing threaded holes for this part. Generally speaking, threaded holes and other processing are hand-tapping and can be processed on CNC equipment. It has a certain technical content, and many companies cannot do this.

At Tianfeng Technology Company, most of the threaded hole processing is basically all processed using CNC equipment, with stable processing quality and beautiful appearance.

As the chief craftsman, Zeng Qinghai also picked up a wall panel that had processed threaded holes, looked at it and said, "Boss, the processing seems to be very good."

Li Tianfeng nodded, then picked up the threaded gauge placed on the work table, and gently twisted it in with the gauges' end. It was very smooth and very easy. Then, he twisted it in with the stop end.

The stop end is very tight, and you can't screw it in just a little bit. Li Tianfeng nodded with satisfaction, and the thread gauge end was smoothly screwed in, and the thread gauge end could not screw in, which means that the thread was qualified.

The "Black Ghost" drone entered the trial processing of structural parts. Not only this one part, Li Tianfeng also looked at the processing of various other structural parts, and the processing conditions were relatively good.

These structural parts are undoubtedly out of the list, all have more or less threaded holes. Mainly after processing, these structural parts will be assembled together to form the overall structure of the drone.

Generally speaking, the structural parts of an aircraft are mostly welded and riveted, and less bolted connections are used. However, this method is rarely used on "Black Ghost" drones. On the contrary, most of them are mostly bolted connections.

In aircraft manufacturing, welding and riveting are widely used, which is a last resort, because we are worried that the bolts will loose during use, so they will be welded or riveted directly.

Tianfeng Technology Company has advanced lock nuts, known as "never loose" lock nuts, so there is no need to worry about loosening of bolts. It uses bolt connections in large quantities. For example, these structural parts will be connected by bolts in the future and finally form the overall structural parts of the drone.

After a look, Li Tianfeng and others went to the parts delivery workshop near the back door. Here, many parts were being inspected, and many parts were being packaged and packed.

The workers carefully wrap each part with foam paper or bubble film, and then pack the box with confidence, and there are many parts in boxes at a time.

A forklift is forking these boxes of parts onto a truck, which will run from here, load containers at the port, and ship to foreign countries, such as Bombardier or Embraer.

Zeng Qinghai said: "Boss, it's busy here. Every day, many large trucks come in and out, and a large number of parts are transported away."

Li Tianfeng pointed out: "In June alone, we signed a processing contract with Bombardier and Embraer for a total of US$720 million. In July, we signed more than 900 million. In a year, there are no US$10 billion, and there are also US$80 billion."

One hundred billion! Or US dollars!

Zeng Qinghai and Lei Yong looked at each other quietly and nodded slightly. They didn't think that the processing business would be so large.

It seems that this time, it is a big profit to establish a strategic partnership with Bombardier and Embraer.

In the parts delivery workshop, Li Tianfeng saw that the workers worked carefully and had clear processes, and they were a little relieved. Li Tianfeng often came here to take a look. Li Tianfeng thought that this was a key workshop, and there were a lot of parts and no mistakes or accidents were allowed.

Li Tianfeng even saw two Bombardier acceptance representatives in the distance, and the parts were being inspected. From the expressions of the two, it can be seen that they seemed to be very satisfied with the processing quality of these parts.

In the office.

Li Tianfeng is on the phone with Zhang Haiping. As one of the heads of the "Black Ghost" drone military, Zhang Haiping often calls to inquire about the progress of the development of the drone. However, sometimes, the two will chat.

Just now, Li Tianfeng had already talked about the development progress of drone development. Zhang Haiping was very happy to learn that Tianfeng Technology Company had completed the aerodynamic design, structural design and avionics system design of drone.

Zhang Haiping said: "Mr. Li, the development progress sounds comfortable. Thinking about the time when we developed that drone, we were so anxious. When we thought about it, I sighed."

At the beginning, the military developed a relatively advanced medium and low-altitude drone, encountered a series of technical difficulties, and the project was finally stranded. Zhang Haiping was the original military leader.

Now that I think about it, Zhang Haiping feels it.

Zhang Haiping said: "Mr. Li, your development is going smoothly, and the development of all airborne equipment has also made good progress. I have implemented them one by one. It was very strange that everyone's development is so smooth, but I quickly understood the reason."

Upon hearing this, Li Tianfeng smiled slightly.

Zhang Haiping said: "It turns out that Mr. Li has provided you with technical guidance, and many experts have given you a thumbs up."

At the beginning, when the development of various airborne equipment was developed, everyone encountered a series of technical difficulties. Some experts even went to Tianfeng Technology Company to complain. Li Tianfeng patiently conducted technical exchanges with everyone.

It is said that it is technical exchange, but in fact, Li Tianfeng provided technical guidance for everyone and solved a series of technical problems for everyone. If these technical problems are cleared, everyone's research and development will naturally progress smoothly.

Even in the past two months, a few experts came over and humbly asked Li Tianfeng for advice. Li Tianfeng never postponed it. He showed good patience and provided technical guidance one by one.

Among the experts, Li Tianfeng is modest, patient, and has a very good reputation. Once everyone encounters technical problems, they either call to ask for advice or come over to ask for advice in person.

Li Tianfeng said: "Minister Zhang, everyone is engaged in technical communication, everyone is too polite."

Of course, Zhang Haiping knew that it was not just technical exchange. Technical exchange was just for the sake of taking care of the experts. What Li Tianfeng said specifically was actually technical guidance.

Zhang Haiping naturally did not point it out and said happily: "Mr. Li, if it weren't for you, we wouldn't have to think about it. We would definitely not be able to develop such an advanced drone."

Li Tianfeng smiled and said, "Minister Zhang, how is the construction progressing of the military's drone ground command center?"

Zhang Haiping laughed and said, "Our military ground command center is progressing smoothly. Mr. Li, you have a great contribution to it."

The military's ground command center is mainly the future command of "Black Ghost" drones, including the takeoff, flight, reconnaissance, ground strikes, target guidance, etc., which is the drone's control center.

Such a ground command center has extremely high technical content. Fortunately, Li Tianfeng provided a lot of technical guidance, and the construction of the ground command center has progressed very smoothly.

The two chatted on the phone for a long time before they ended happily. From the call just now, it can be seen that Zhang Haiping was very happy and was very satisfied with the progress of the development of the drone.

………

Materials Engineering Center.

In a certain laboratory, several experts wearing white coats are conducting experiments. If an expert can tell at a glance that this is an experiment of a certain wave absorbing material.

One of the advanced features of the "Black Ghost" drone is its stealth performance. According to the design, the stealth performance of the "Black Ghost" drone will be above the b2 bombing in the United States.
