Seongnam Base, Aircraft Design and R&D Center.

In one of the small conference rooms, several design experts and design backbones are discussing the structural design of the Y-30 transport aircraft, and on the conference table, there are a lot of design sketches, and if you look closely, you will find that these design sketches are all from Li Tianfeng's hand.

One of the design backbones said: "The structural design of our Y-30 transport aircraft is too advanced, and it is only now that I have digested and understood these design sketches of Mr. Li." ”

Another person: "Yes, I am similar, the structural design of the Y-30 transport aircraft is simply breathtaking, almost beyond our cognition, it is conceivable that with such an advanced structural strength design, our Y-30 transport aircraft will be very solid." ”

Seeing that everyone is praising the structural design of the Y-30 transport aircraft, one of the design experts said: "Our Y-30 transport aircraft, its structural design scheme is a new design, very scientific, fortunately there are Mr. Li's design sketches as a guide, otherwise, we would never have thought of such an excellent design scheme." ”

Yun-30 transport aircraft, the main beam is made of high-strength titanium alloy, the structural parts are mainly titanium alloy and "Hercules" materials, and the proportion of aluminum alloy is relatively small.

Li Tianfeng's structural design is famous, in later generations, this is a famous large transport aircraft using the structural design scheme, in this famous large transport aircraft, after enough testing and verification, can be described as very mature.

Li Tianfeng adopts the doctrine of taking and directly borrowing the structural design scheme of this large transport aircraft, which is naturally very advanced and excellent in everyone's opinion.

If there are later generations of "crossing" people, if you see the design of the Yun 30. It will definitely be a big exclamation, because the Y-30 is a very famous and famous large military transport aircraft in later generations.

The design experts of the aircraft design and R&D center have increased from seven at the beginning of its establishment to twenty or thirty now, including several structural design experts.

in the conference room. The oldest design expert straightened his reading glasses, and then said: "Mr. Li's design sketches, we have discussed and exchanged many times, presumably everyone has digested and absorbed, from today onwards, we will carry out detailed specific design on the basis of these design sketches, if you have any questions in the design process, you can find me and Lao Zhang." ”

Lao Zhang is another structural design expert. Very level. As a design expert, everyone understands and fully understands Li Tianfeng's structural design plan, so this expert said that if there is any problem, you can directly find him and Lao Zhang.

There are many conferences like this, big and small. At the Aircraft R&D Center, many sessions are held almost every day. Since entering the full development of the Y-30 transport aircraft, the entire aircraft design and development center has been much busier.

Although busy, everything is in order, and this series of design sketches drawn by Li Tianfeng himself has played a great role.

The role of these sketches is a bit like the design and development of the cheat, the Y-30 transport aircraft. Directly into the fast lane, there are almost no detours, and there are no thorny technical problems.

Without these design sketches, the demonstration and verification of various design schemes will directly consume a lot of manpower and material resources. With these sketches, all kinds of arguments and verifications are directly omitted, the design plan is directly determined, and everyone starts to design directly.

When the design and development of the Y-30 transport aircraft was fully rolled out, many people heard the news that another transport aircraft was about to be designed and developed.

"Lao Guo, I heard that we will start developing another transport aircraft, I don't know if it's true?"

"Well, I've heard about it, and it looks like it's real."

“”

The Y-25 transport aircraft will enter the international export market, there is no need to keep it secret, and in addition to the preparation of the design technical outline, many people in the aircraft design and development center know about the Y-25 transport aircraft.

"Y-25 transport plane! It turns out that such a transport aircraft will really be developed! ”

"This is also a large transport aircraft, with a take-off load of 100 tons, which is also very powerful!"

"Haha, I didn't think about it, we will develop another transport aircraft."

"Yes! Yun 30 transport plane, big fat man, Yun 25 transport plane, little fat man, good, good! ”

“……”

The news confirmed, many people had a heated discussion, especially the technical staff of the design and development center, everyone frowned, and did not think that they were fortunate to start the research and development of two transport aircraft almost at the same time.

The design outline of the Y-30 transport aircraft, as a design and development personnel, everyone basically understands better, and we know that the Y-30 transport aircraft is very excellent, very good, and is definitely the best and most advanced large transport aircraft in the world.

Yun-25 transport aircraft, you can even imagine, this transport aircraft will definitely be very good, very advanced, in terms of technical content and advancement, I am afraid that it will not be much worse than the Yun-30 transport aircraft.

A group of design experts and design backbones led by Lei Yong are compiling the technical outline for the design of the Y-25 transport aircraft.

Everyone's heated discussion more or less came into Lei Yong's ears, and when he heard everyone's hot discussion, Lei Yong sometimes smiled slightly, thinking in his heart, yes, the Y-25 transport aircraft will also be very good.

In the office.

Li Tianfeng is full of interest, and he is doing it himself, and is drawing a 3D color map of the Y-25 transport plane, and the drawing is basically close to completion.

This is also a large transport aircraft, which is also considered a giant, only slightly smaller than the American C-5 transport aircraft, but definitely much larger than the C-130.

According to Li Tianfeng's assumption, the Y-25 transport plane will be about 70 meters long, with wings of more than 60 meters, and a height of 17 or 8 meters.

The Y-25 transport aircraft will be the same as the Y-30 transport plane, one of its biggest features is the design of the cargo hold, which will be a wide and large cargo compartment, so the fuselage will be very thick from the outside, and the Y-25 transport aircraft is also known as the "little fat man".

In his mind, he already had a plan for the design of the Y-25 transport plane, and Li Tianfeng drew the 3D design color map of the Y-25 transport plane without any stagnation, and there was no need to stop and think about anything, almost in one go, and it only took two or three days of effort, and the vivid Y-25 jumped on the computer.

If you don't look closely, you still think it's a physical photo, a color map of the Y-25 transport plane, how much Li Tianfeng has drawn, from all angles, and the nose of the machine is opened, revealing the color map of the panoramic view of the warehouse inside.

Seongnam base.

The door of the No. 2 assembly plant slowly opened, and under the traction of a tractor, a J-18 fighter slowly drove out.

After one or two months of test flights, the J-18 finally entered small batch production, which is the first official J-18 fighter, and the first J-18 fighter was delivered to the military.

As for the production of export-oriented J-18 fighters, it will also begin, and soon after, J-18 fighters will begin to be delivered to foreign users one after another.

The two assembly production lines of the No. 2 assembly workshop, one for the production of J-30 fighters and the other for the production of J-18 fighters, the two production lines are all on the right track, and they have begun to plan and manufacture in an orderly manner.

As the production of J-18 fighters enters a small batch, there may be almost a day or two before J-30 fighters or J-18 fighters leave the assembly line from the No. 2 assembly workshop and are towed to the airport next to it by a tractor.

At present, the apron of the airport is still relatively empty, and it is estimated that after the J-30 and J-18 fighters all enter mass production, it will definitely be neat and tidy, and the J-30 and J-18 fighters to be delivered to users will be parked.

This J-18 fighter, out of the No. 2 assembly workshop, parked on the airport runway ready to take off, the aircraft has been inspected, and it is the joint acceptance of the military and Tianfeng Technology Company, the military is very satisfied with the quality, and now it is only waiting to be delivered.

A refueling truck drove over, several ground crew members filled up the J-18 fighter, and a pilot was ready to go, and soon after, the pilot boarded the fighter.

The fighter started up, moved on the runway, and kept accelerating, getting faster and faster, and soon flew into the blue sky, flying towards the distant sky.

This J-18 fighter took off from here, flew directly to a certain airfield of the Air Force, and arrived at a certain division of the Air Force, which is also the first air force division to officially install J-18 fighters.

In the near future, with the official installation of J-18 fighters, there will definitely be more and more air force divisions equipped with J-18 fighters.

It is conceivable that within a few years, the Air Force will complete a large-scale rearmament, and the J-8 fighters that are still being equipped will be completely eliminated, and a situation will be formed in which J-30 fighters and J-18 fighters will be the mainstay, supplemented by J-10 and J-11 fighters.

It is even possible that after a few more years, J-10 and J-11 fighters will also be replaced, and almost all of them will be J-30 fighters and J-18 fighters.

According to the military's preliminary plan, with the large-scale installation of J-30 fighters and J-18 fighters, the Chinese army will be equipped with more than 300 J-30 fighters, and more than 2,000 J-18 fighters, or even more.

……

Great northwest, a desert.

It is endless, sparsely populated, full of deserts and next door, typical of no man's land, which has always been desolate and silent, and in its center, it has recently become lively.

Here, a lot of construction machinery is under construction, and the people involved in the construction are all in military uniforms.

According to the plan, the construction here will become a huge parking airport, enough to park thousands of various aircraft, with the J-30 and J-18 fighters began to be formally installed in the troops, all kinds of aircraft will be parked here, here will be all kinds of aircraft storage ground.

The climate here is dry, there is little rain all year round, which can greatly slow down the rust and oxidation of various metals, and is the best place to store aircraft.

The J-30 and J-18 fighters began to be installed in the troops, and the military has begun to make such plans, choosing to build a huge aircraft storage yard here.
