Not far from the elevator, it was a large office, a big office where dozens of people worked together. In the office, everyone was busy, busy with the design and development of the Yun-30 and Yun-25 transport aircraft.

At the beginning, no one noticed Xie Xiaolan and Li Tianfeng. Xie Xiaolan was obviously satisfied with Li Tianfeng, a free porter.

Xie Xiaolan said: "This is my place. Just put the information on my desk. Thank you today!"

Li Tianfeng put the information on Xie Xiaolan's desk as he said. Even a gentle beauty wearing big glasses next to him said jokingly: "Xiaolan, where did you catch a free laborer? She looks quite handsome."

Obviously, this beautiful woman with big glasses doesn't know Li Tianfeng either.

Xie Xiaolan smiled proudly, and her eyes seemed to say, Who am I? I am one of the big beauties in our company. The charm of this beauty is naturally great.

Li Tianfeng is about to leave.

At this time, a middle-aged man with a majestic look on his face walked in, and many people around him greeted the middle-aged man, "Hello, Director!"

"Hello, Director Yan!"

Director Yan nodded and looked around the office. Seeing that everyone was busy, he couldn't help but nodded with satisfaction. However, Director Yan was stunned immediately, stunned, and even rubbed his eyes in disbelief.

No way!

I saw Li Tianfeng holding a lot of information and putting it on Xie Xiaolan's table, while Xie Xiaolan was talking and laughing, as if she didn't know Li Tianfeng yet.

Confirm that I read it correctly. This is indeed Li Tianfeng. Director Yan had the half-majesty he had just now on his face. He walked over quickly and said with a respectful look: "Mr. Li, why are you here?"

Li Tianfeng looked around and saw Director Yan, and seemed to have an impression that he was one of the deputy directors of the more than a dozen design rooms below the Aircraft Design and R&D Center. He seemed to be surnamed Yan.

Li Tianfeng said: "You are Director Yan, right? I just came here. I am going to see the progress of the design and development of Yun30 and Yun25."

Xie Xiaolan next to him and the beautiful woman with big glasses just now were stunned. Xie Xiaolan even asked blankly: "Director, which Mr. Li is this?"

Director Yan glared at Xie Xiaolan with anger and said, "How many Mr. Li in our company are there? This is Mr. Li Tianfeng, President of our Tianfeng Technology Company."

OMG!

Xie Xiaolan was completely stunned and didn't react for a long time. She accidentally grabbed a free labor force, and even arrested the most *oss of her company and transported the information for herself.

Li Tianfeng smiled slightly, ignored Xie Xiaolan, and ignored many design and development personnel who stood up with surprise and even shock on their faces. Li Tianfeng said: "Director Yan, you are busy."

Director Yan quickly followed Li Tianfeng, politely and respectfully sent Li Tianfeng out of this big office. The moment he left the office, Director Yan turned around and glared at Xie Xiaolan fiercely, his eyes as if saying, Xie Xiaolan. You have caused a big disaster, see how I will deal with you later.

When Li Tianfeng and Director Yan both left this big office, the entire office was in an uproar.

"My God! This is our Mr. Li just now!"

"Xie Xiaolan, you are so awesome!"

"Catch our Mr. Li to act as a free porter, Xie Xiaolan, I am convinced of you!"

“…”

Facing the totally upset colleagues, Xie Xiaolan was anxious and said with great grievance: "I. I don't know us Mr. Li, if I had known it, I wouldn't dare to ask Mr. Li to help me transfer information!"

I'm so anxious!

Xie Xiaolan almost burst into tears, but someone next to her said, "Xiaolan, don't worry, our Mr. Li is approachable and won't care about these things."

After saying this, Xie Xiaolan stopped the tears that almost fell, and thought to herself that Mr. Li had no airs just now, and was like a big brother next door.

...

Lei Yong's office.

Li Tianfeng knocked on the door and walked in. When he saw Li Tianfeng, Lei Yong quickly stood up and said, "Boss, you are here." As he said that, Lei Yong skillfully made hot tea for Li Tianfeng.

Li Tianfeng said: "Mr. Lei, how is the overall structural design progress of our Y-30 transport aircraft?"

As a transport aircraft, the overall structural design is crucial, especially a large transport aircraft like the Ship30 transport aircraft that can air 200 tons of cargo at one time.

Of course, being able to transport 200 tons of goods at a time is not a big skill. Even larger than the transportation of the 30 are super huge transport aircraft such as the 225.

The best thing about the 30 transport aircraft is that the warehouse is very wide. If the warehouse is wide, the transportation capacity will be greatly enhanced. Many big guys are loaded into the warehouse of the transport aircraft.

It is not that simple to design a warehouse with a wide range of cargo warehouses. This involves all aspects. If the warehouse is wide, the requirements for the overall structural strength of the aircraft will be greatly strengthened and the technical requirements are much higher.

Because of this, many transport aircraft do not have large warehouses. The American-5 "Galaxy" transport aircraft is considered a large transport aircraft, but the maximum width of its warehouse is only a little over 5 meters.

An225 is the largest transport aircraft in the world, but its maximum width of the cargo warehouse is only 6.4 meters. Our 30 transport aircraft has a warehouse width of 7.8 meters, which is enough to park 3 large trucks side by side.

The width of the warehouse is 7.8 meters, which is enough to be the first seat in the width of all transport aircraft warehouses in the world. Of course, not only the width of the warehouse is huge, but the volume of the warehouse is also very huge, with a volume of more than 1,000 cubic meters.

The cargo warehouse is so wide that the aircraft body looks very wide from the outside, and is inherently known as the "big fat man".

Such a large cargo warehouse, coupled with the ability to carry the main battle tank, the structural strength of this pair of cargo warehouses is very high. Otherwise, the main battle tank of 50 to 60 tons will not be directly crushed by the cargo warehouse.

Knowing that the structural strength design of the Y-30 transport aircraft is very important, Li Tianfeng is very concerned about it. Every three or five days, he will ask about the overall structural design of the Y-30 transport aircraft.

As for the Y-25 transporter, if the structural design of the Y-30 transporter can be completed well, the structural strength design of the Y-25 transporter will not be difficult.

Of course, the 25 transport aircraft is also designed with a wide warehouse. The width of the warehouse is nearly six meters long, and it can accommodate two large trucks side by side, allowing more than a dozen large trucks to be transported at one time.

As the chief designer of the Y-30 transport aircraft, Lei Yong naturally knows the importance of its structural design and pays attention to structural design almost every day. If he encounters design problems, he will hold a design technical meeting in person to solve the technical problems he encounters together.

Lei Yong said: "Boss, with the large number of design sketches you provide as guidance, the overall structural design of our Y-30 transport aircraft has been progressing smoothly. We have completed the design of several key structural parts, such as the main beam design of the aircraft, partition frames, wall panels and other designs.

Everyone knows the main beam of the aircraft, and the partitions, wall panels, etc. are also the main and important parts that make up the aircraft structure.

These structural parts are designed in place, and combined with other structural parts, these parts are combined to form the main structure of the Y-30 transport aircraft.

With skinning, avionics systems, various instruments, auxiliary equipment and accessories, etc., the Y30 will basically be formed.

Lei Yong turned on his computer. There were many finished structural parts in the computer. Li Tianfeng was not polite, so he sat in front of the computer and looked carefully.

These are structural parts that have just been initially designed in the past few days. These structural parts are basically "Hercules" materials. Only a small number of structural parts with relatively high rigidity requirements are made of titanium alloy.

As for the aluminum alloy materials commonly found in aircraft design and manufacturing, they are already rare in the design of the Y-30 transport aircraft, and are basically replaced by "Hercules" materials and various other non-metal composite materials.

Because the materials are basically based on "Hercules" materials, the quality of the Y-30 transport aircraft is much lighter and stronger and stronger than that of the Y-5 transport aircraft and the A-225 transport aircraft.

It is precisely because of the "Hercules" materials that the cargo warehouse of the 30 transport aircraft is designed to be so wide that it can park 3 large trucks side by side.

The American-17 Global Overlord Transporter is one of the largest military transporters with the best comprehensive performance. It has a maximum load of about 77 tons. It also adopts a wide warehouse design with a width of 5.5 meters. With such a width, two large trucks can be parked side by side in the warehouse.

The Y-30 transport aircraft has a cargo warehouse width of 7.8 meters and a maximum load capacity of 200 tons. With such a huge aircraft, the airplane weight is almost the same as the airplane of the American-17. This shows that the design of the Y-30 transport aircraft is advanced.

Li Tianfeng looked at it for a long time and then said: "There are basically no major problems in the design of these structural parts. After the main structural design is completed, we can simulate and simulate the structural parts in the computer, assemble the overall structure in the computer."

Lei Yong said: "I guess in about one month, we will be able to design almost all structural parts and simulate and assemble them in the computer."

After the main structural parts are assembled in the computer, the structural design of the entire 30 transport machine can be seen.

The structural design of the Y-30 transport aircraft adopts a new design concept, and the widespread use of "Hercules" materials, the whole machine is light and sturdy, and the cargo warehouse can withstand the easy entry of dozens of tons of main battle tanks.

After reading the design of the structural parts, Li Tianfeng said: "Mr. Lei, in addition to the advanced structural design, our Y-30 transport aircraft is also very different from other traditional transport aircraft."
