Seongnam base.

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

Figuratively speaking, this is the main skeleton or frame diagram of the Y-30 transport aircraft, which is different from the general transport aircraft design, which is a more advanced structural design than the American C-17 and C-5 transport aircraft.

This kind of structural design is famous in later generations, and it has gradually become the mainstream structural design of large aircraft, and this structural design also has a very famous name, which is called "Wu Zhenguo" design.

This is a brand-new aircraft structure design designed and developed by Wu Zhenguo, a great Chinese aircraft designer, in the thirties and forties of the 21st century.

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

In this era and time and space, Li Tianfeng went to look for "Wu Zhenguo", but there was no such person, Li Tianfeng even wondered if the development trajectory of the times had changed a lot, and whether the memory of the future generations in his mind was another parallel time and space.

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

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

More importantly, although this structural design is very advanced, it is not complicated, and it is not a troublesome thing to manufacture in the future.

On the contrary, because the structural design is advanced. The extensive use of integrated design greatly reduces the number of parts, compared to the traditional production of aircraft structural components. In terms of production and manufacturing, the "Wu Zhenguo" type is more convenient, the production and manufacturing cost is lower, the aircraft is lighter, and the structural strength is higher, that is to say, the aircraft adopts this structural design. It is both light and strong.

Lightweight and sturdy, that's what aircraft design is all about.

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

With these sketches, everyone's design progress is relatively fast. Start the design in January. It was only April, and in just three or four months, the structural design of the Y-30 transport aircraft was basically completed.

The general drawing of the structural design is very large, and it is covered with this large reading table in Li Tianfeng's office, and there are several such large drawings.

Li Tianfeng held a ruler, a pencil, and an eraser, and looked very carefully and carefully, and no one knew the structural design of this new concept better than Li Tianfeng.

In your own office. Li Tianfeng watched it all day, and looked at the picture again. I calculated it myself, and many of these large drawings had to be changed, and there were a lot of handwriting written in pencil on them.

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

Of course, there are no major problems, but there are many places that need to be improved and designed, and after Li Tianfeng's modification, the structural design of the Y-30 transport aircraft is more perfect and advanced.

After reading the drawings and revising and perfecting them from beginning to end, Li Tianfeng couldn't help but breathe a long sigh of relief, which can be regarded as the completion of a big project.

The structural design of the Y-30 transport aircraft has been completed, and the overall skeleton has come out, which is a very important step in the design.

"Mr. Lei, come here."

After receiving a call from Li Tianfeng, Lei Yong naturally came over early, and was full of astonishment when he saw the design drawings on the table that had changed a lot.

In Lei Yong's view, the structural design of the Y-30 transport aircraft is very advanced, and it is necessary to throw off those traditional transport planes several streets in terms of advancement.

After the completion of such an advanced structural design, Lei Yong personally organized a group of experts to demonstrate, analyze, review, modify and improve many times before Lei Yong sent these drawings to Li Tianfeng for checking.

With such an advanced and advanced design, Lei Yong believes that it has almost reached the limit of his own design level, and he did not think that in Li Tianfeng's eyes, there is still such a large space for improvement.

In addition to being stunned, Lei Yong's eyes only had admiration, and he simply admired Li Tianfeng's technical level.

Seeing Lei Yong's admiration, Li Tianfeng smiled and said: "The structural design of our Yun-30 transport aircraft, after I have perfected and modified it, there is no problem, and the formal design drawings will be formed immediately, and we can also start trial production of some structural parts." ”

In Tianfeng Technology Company, it is very common to carry out design and research and development while carrying out 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 finalized, and it is basically impossible to make major changes in the design, and it is completely possible to form formal design drawings, and then carry out trial production and process verification of parts.

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

Li Tianfeng nodded and said: "With the completion of the structural design of the Y-30 transport aircraft, a series of other designs, such as avionics systems, control systems, etc., will also be completed one after another. ”

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

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

However, the majority of design and development personnel and employees of Tianfeng Technology Company have long been surprised, such miracles have not only happened in the body of the Yun-30 transport aircraft, before that, we have created one miracle after another.

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

After thinking about it, Lei Yong said: "Boss, this advanced structural design of our Yun-30 transport aircraft, everyone has taken a name behind it, called 'Tianfeng-style' structural design. ”

Peak style!

Li Tianfeng was happy, and he didn't think that everyone called this kind of structural design "Tianfeng-style" structural design.

This structural design can not only be used in large transport aircraft, but also in other large aircraft, such as civil large passenger aircraft, military air tankers, long-range strategic bombers and so on.

Li Tianfeng said with a smile: "Yes, it will be called 'Tianfeng-style' structure in the future, in addition, the domestic patent of 'Tianfeng-style' structural design should also be passed, and the application for international patents will be successful in the near future." ”

Tianfeng Technology Co., Ltd. applies for a lot of various patents every year, and has its own special patent application department, and the patent application department applies for all kinds of patents naturally and well, and the "Tianfeng-style" structural design will definitely obtain domestic and international patents.

One step ahead, one step at a time.

Tianfeng Technology Co., Ltd. has applied for a large number of domestic and international patents in the design and development of aero engines, as well as aircraft design and development.

With the extensive use of new designs and new process technologies, Tianfeng Technology Company is undoubtedly at the forefront of the world in technology, and has a tendency to become the world's leader in technology.

The Y-30 transport machine completed the structural design, the basic design of the structural parts was finalized, and the major production and manufacturing workshops began the trial production and process verification of the structural parts of the Y-30 transport aircraft.

That is to say, 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 have been rolled out, which will undoubtedly greatly save the time of trial production and process verification of parts.

……

The Y-25 transport plane may enter the international arms sales market in the future and will be exported to a large number of countries, and the reputation of the Y-25 transport plane is very great in the world.

The Y-30 transport aircraft has been kept secret, but there is no impermeable wall in the world, and some people still know that the Chinese side is developing a larger and more advanced transport aircraft than the Y-25 transport aircraft.

United States, Pentagon.

The director of the US intelligence department was reporting the situation to the US Secretary of Defense, and the intelligence chief said: "Mr. Secretary of Defense, according to our investigation and the information we have, in addition to developing the Y-25 transport plane, the Chinese side is also developing a larger and more advanced super transport plane. ”

Super Transporter!

The US Secretary of Defense looked solemn, and the Y-25 transport plane made the US Secretary of Defense feel a lot of pressure, because the US side came to the conclusion after assessment that the overall performance of the Y-25 was superior to that of the C-5 "Galaxy" transport plane.

The Y-25 transport aircraft is sufficient as a strategic airlift force of the Chinese Air Force, and there are larger and more advanced transport aircraft than the Y-25 transport aircraft, what is the concept?

The U.S. Secretary of Defense said slowly: "According to the information you have, what is the specific performance of the transport aircraft that the Chinese side is secretly developing?" ”

The intelligence chief said: "Mr. Defense Minister, according to the information we have, the transport plane that the Chinese side is secretly developing is the 'Y-30' transport plane, because the Chinese side is strictly secret, and the specific parameters are ominous. ”

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

The take-off load is over 200 tons!

The range is nearly 20,000 kilometers!

After a full half ring, the US defense secretary came back to his senses and said in a heavy voice: "If the Chinese side succeeds in developing both the Y-30 and Y-25 transport planes, the Chinese military's airlift capability will surpass ours ours and become the country with the most powerful airlift capability in the world." ”

At present, the US military's airlift capability is undoubtedly the world's top, and there are not only C-130 "Hercules" transport planes, but also C-17 "Globemaster" transport planes, and C-5 "Galaxy" transport planes.

In addition to these transport aircraft, there are quite a few other transport aircraft, such as helicopters, such as the "Osprey" transport aircraft and so on.

Beyond the United States!

The world's most airlifted capacity!

The intelligence chief's face changed slightly, and he thought to himself, the situation is very serious.
