City South Base.

In the office, Li Tianfeng was looking at the general diagram of the structural design of the Y-30 transport aircraft sent by Lei Yong.

To put it more vividly, this is the main skeleton or frame diagram of the Y-30 transport aircraft. It is different from the general transport aircraft design. This is a structural design that is more advanced than that of the US C-17 and C-5 transport aircraft.

This structural design was famous in later generations and gradually became the mainstream structural design of large aircraft. This structural design also has a very famous name, which is called "Wu Zhenguo" style design.

This is a brand new aircraft structural design designed and developed by Wu Zhenguo, the great Chinese aircraft designer in the 1930s and 1940s.

Speaking of "Wu Zhenguo", there is still a great relationship with Li Tianfeng, because in later generations, Wu Zhenguo was Li Tianfeng's mentor.

In this era and time and space, Li Tianfeng has searched for "Wu Zhenguo", but no one has been found. Li Tianfeng even wondered if the development trajectory of the times has changed a lot, and if the memories of future generations in his mind are another parallel time and space.

"Wu Zhenguo" cannot be verified, but this advanced aircraft structural design was taken out by Li Tianfeng and used for the first time on a large transport aircraft like the Y-30.

With this structural design, the structural strength of the transport aircraft is greatly enhanced, and there is no problem even if it is a wide warehouse with a width of 7 or 8 meters.

When it is more important, although this structural design is very advanced, it is not complicated, and future production and manufacturing will not be a hassle.

On the contrary, because of the advanced structural design and the widely adopted integrated design, the number of parts has been greatly reduced. Compared with the traditional production and manufacturing of aircraft structural parts, the "Wu Zhenguo" type is more convenient in production and manufacturing, with lower production costs, and is lighter in aircraft and has higher structural strength. In other words, the aircraft adopts this structural design, which is both light and sturdy.

It is both light and sturdy, which is exactly the purpose of aircraft design.

Because this structural design was first adopted, Li Tianfeng personally drew a large number of design sketches. These design sketches not only marked the main design dimensions, but also gave design technical requirements.

With these sketches, everyone's design progress is also relatively fast. The design started in January, and it was only April. In just three or four months, the structural design of the Y-30 transport aircraft has been basically completed.

The overall structural design drawings are very large, covering the large reading table in Li Tianfeng's office, and there are several such large drawings.

Li Tianfeng held a ruler, pencil, and eraser and looked at it very carefully. No one knew better than Li Tianfeng's structural design.

In his office, Li Tianfeng looked at it all day long. He looked at the pictures and calculated them himself. Many places had to be modified in many places, and there were even more handwriting written in pencil.

Of course, Lei Yong sent these large drawings to Li Tianfeng after organizing the design review, improvement and modification, and then confirmed that there were no problems.

Of course there is no major problem, but there are many areas that require improvement and design. After Li Tianfeng's modification, the structural design of the Y-30 transport aircraft has become more perfect and advanced.

After reading the drawings and modifying them from beginning to end, Li Tianfeng couldn't help but breathe a sigh of relief. It was considered to have completed a major project.

The structure design of the Y-30 transport aircraft has been completed and the overall skeleton has been released, and a very important step has been completed in the design.

"Mr. Lei, come here."

After receiving a call from Li Tianfeng, Lei Yong naturally came over early and saw the design drawings on the table with considerable changes. Lei Yong was shocked.

In Lei Yong's view, the structural design of the Y-30 transport aircraft is very advanced, and to a degree of advanced level, it is far superior to those traditional transport aircraft on several streets.

After completing such advanced structural design, Lei Yong personally organized a group of experts to conduct argumentation, analysis, review, revision and improvement many times, Lei Yong gave these drawings to Li Tianfeng for inspection.

Lei Yong believed that such advanced and advanced design was almost at the limit of his design level. He did not think that in Li Tianfeng's eyes, there was still such a lot of room for improvement.

In addition to being shocked, Lei Yong had only admired him in his eyes, and he was so impressed by Li Tianfeng's technical level.

Seeing Lei Yong's eyes full of admiration, Li Tianfeng smiled and said, "After I have improved and modified it, there will be no problem with it. I will immediately form a formal design drawing and some structural parts. We can also start trial production."

At Tianfeng Technology Company, it is very common to conduct design and research and development while conducting trial production and verification of parts.

If the structural design of the Y-30 transport aircraft is completed, the main structural parts will be designed and shaped, and it is basically impossible to make major design changes. It is possible to form formal design drawings, and then trial production and process verification of parts are carried out.

Lei Yong said: "Boss, let's form the formal design drawings as soon as possible."

Li Tianfeng nodded and said, "As the structure design of the Y-30 transport aircraft is completed, a series of other designs, such as avionics systems, control systems, etc., will be completed one after another."

From the start of design in January, the design and development of the Y-30 transport aircraft, a large number of design sketches, and the guidance and attention of Li Tianfeng, the progress can be said to be rapid. It is estimated that the comprehensive design will be completed by June and July.

It is a miracle to complete the comprehensive design of such a transport aircraft in about half a year!

However, the vast number of design and R&D personnel of Tianfeng Technology Company have long been accustomed to it. Such miracles not only happened to the Y-30 transport aircraft, but have created one miracle after another before.

Two or three months later, the complete design of the fully-equipped 30 transport aircraft was confident, and Lei Yong nodded confidently.

After thinking about it, Lei Yong said: "Boss, everyone has named the "Tianfeng" structural design of our Yun-30 transport aircraft."

Tianfeng style!

Li Tianfeng was happy and did not think that everyone called this structural design "Tianfeng-style" structural design.

This structural design can not only be used on large transport aircraft, but also on various other large aircraft, such as civilian large passenger aircraft, military aerial refueling aircraft, long-range strategic bombers, etc.

Li Tianfeng smiled and said, "Yes, it will be called the 'Tianfeng-style' structure in the future. In addition, the domestic patent for the 'Tianfeng-style' structure design should also be passed, and the application for international patents will be successful soon."

Tianfeng Technology Company applies for many types of patents every year, and has its own special patent application department. The patent application department applies for various types of patents. Natural light vehicle driving is familiar with the "Tianfeng" structural design, and will definitely obtain domestic and international patents.

Lead one step, lead one step.

Tianfeng Technology Company has applied for a large number of domestic and international patents in the design and development of aircraft engines and aircraft design and development.

With the widespread use of new designs and new process technologies, Tianfeng Technology Company is undoubtedly at the forefront of the world in technology and has a trend of becoming the world's leader in technology.

The Yun30 transport machine has completed structural design and basic design and shaping of structural parts. The major production and manufacturing workshops have begun trial production and process verification of structural parts of the Yun30 transport machine.

In other words, from now on, the design and development of the Y-30 transport aircraft has not yet ended, and the trial production and processing of many parts has been put into use, which will undoubtedly greatly save the time of trial production and process verification of parts.

...

The Y-25 transport aircraft may enter the international arms market in the future and will be exported to a large number of countries. The Y-25 transport aircraft is very famous internationally.

The Y-30 transport aircraft has been kept confidential, but there is no airtight wall in the world. Some people still know that China is developing a larger and more advanced transport aircraft than the Y-25 transport aircraft.

Pentagon, USA.

The U.S. Intelligence Director is reporting the situation to the U.S. Defense Secretary, the intelligence director said: "Mr. Defense Secretary, based on the information we have investigated and mastered, China is also developing a larger and more advanced super transport aircraft in addition to developing the Y25 transport aircraft."

Super transport aircraft!

The U.S. Defense Minister looked solemn, and the Y-25 transport aircraft made the U.S. defense minister feel stressed because the U.S. side concluded after evaluation that the overall performance of the Y-25 is above the C-5 "Galaxy" transport aircraft.

The Y-25 transport aircraft is enough as the strategic air transport force of the Chinese Air Force, and there are also larger and more advanced transport aircraft than the Y-25 transport aircraft. What is this concept?

The US Defense Minister said slowly: "Based on the information you have, what are the specific performances of the transport aircraft that China is secretly developing?"

The intelligence chief said: "Mr. Defense Minister, based on the information we have, the transport aircraft that China is secretly developing is the "Yun30" transport aircraft, because China is strictly confidential and the specific parameters are ominous."

"However, according to our analysis, the load load of the Y-30 transport aircraft should be more than 200 tons and have an extremely long range, with an estimated range of nearly 20,000 kilometers."

The take-off load capacity exceeds 200 tons!

The voyage is nearly 20,000 kilometers!

It took a long time before the US Defense Minister came to his senses and said heavily: "If China successfully develops both the Y-30 and Y-25 transport aircraft, the squadron's air transport capacity will surpass us and become the country with the most powerful air transport capacity in the world."

At present, the US military's air transport capability is undoubtedly the world's top. In terms of transport aircraft, there are not only the C-130 "Hercules" transport aircraft, but also the C-17 "Global King" transport aircraft, and the strategic transport aircraft, the C-5 "Galaxy" transport aircraft.

In addition to these transport aircraft, there are many other transport aircraft, such as helicopters, "Osprey" transport aircraft, etc.

Beyond the United States!

The world has the strongest air transport capability!

The intelligence director's face changed slightly, and he thought to himself that the situation was very serious.
