Chapter 336 is still the world's top

The system said, "Master, don't worry, it is definitely the top in the world. If the C-17 Globemaster of the Beautiful Country is a third-generation large military transport aircraft, ours is definitely a fourth-generation military transport aircraft, and it is definitely ahead of it." generation."

"However, such an advanced military transport aircraft costs a lot of time points. One time point is definitely not enough."

Lin Feng didn't bother to talk nonsense with it, he knew too much about the virtues of the system, so he asked directly, "Two points, no more."

The system also wanted to offer a price of four or five times points, but Lin Feng directly killed it in the bud, without giving him a chance at all, "I can't increase the price, otherwise, I will organize our thousands of designers to develop it myself."

Of course, this is to scare the system. Even if Leihuo Technology Industrial Group has thousands of design and development personnel, how can it compare with the system? It's a thousand miles away, okay?

However, the system was obviously intimidated by Lin Feng, and the transaction was made directly at two times. After a few minutes, the complete set of design and process information about this transport plane was instilled into Lin Feng's brain.

Still the same, these materials are not instilled by the outside world at all, but as if they belonged to Lin Feng's memory, they can be digested and fully understood in a short time.

Big profit again this time!
As the system said, this is definitely the world's top-level large-scale military transport aircraft, and its performance in all aspects is far ahead of similar large-scale military transport aircraft from all over the world.

There are two biggest highlights. One is its four turbofan engines, with large bypass ratio, low noise and vibration, high safety, etc., which are not inferior to civilian turbofan engines at all.

We know that the large bypass ratio turbofan engines used on large airliners are different from those used in the military. In addition to economy, comfort is also emphasized, which requires excellent noise, vibration, safety and reliability.

This large military transport aircraft developed by the system uses four turbofan engines with high bypass ratio, the kind with high fuel efficiency. Such engines are also very excellent as the power of large passenger aircraft.

In addition to the excellent turbofan engine with a large bypass ratio, there is another bright spot, which is the extensive application of carbon fiber materials, coupled with an appropriate amount of titanium alloy materials, the structural strength of this aircraft is super high, and its weight ratio is higher than that of the same class. The transport plane is much lighter, and the saved weight can carry more things.

The performance parameters of this aircraft are as follows:

Length: 56.2 meters

Wingspan: 53.6 meters

货仓尺寸：23.8×5.9×4.2米（可载124名全副武装的步兵/36副担架/54名伤员及医护人员）

Empty weight: 102.6 tons

Load: 112 tons

Maximum take-off weight: 320 tons

Power: 4 non-afterburning turbofan engines with high bypass ratio

Thrust: 4×198 kN
Maximum flying speed: 850 km/h
Maximum ceiling: 14800 meters

Maximum voyage: 15600 kilometers
Design service life: 40 years

Lin Feng "looked through" some parameters of this aircraft in his mind, and Lin Feng admired it very much. The payload of the C-300 Globemaster is only 112 tons.

Of course, the maximum take-off weight of the Globemaster is about 285 tons, and the maximum take-off weight of the aircraft designed and developed by the system is 320 tons. Point five times.

This is bullshit!
It also has a bunch of other technical features that really shine!
For example, if necessary, short-field emergency take-off and landing on unrenovated roads is possible.

For example, the cargo warehouse has a large space, and six military trucks can be parked side by side, or a total of four Tianlong transport helicopters. The cargo cargo floor is reinforced by titanium alloy longitudinal beams, reaching a maximum load capacity of 70 tons, which can be used by main battle tanks. A total of two main battle tanks can be loaded, or four armored personnel carriers.

After "reading" these technical materials in his mind, what Lin Feng likes most is the appearance of this aircraft. It looks beautiful. What Lin Feng wants to do most is not to write out its design technical outline, but I want to draw its real color map.

Just do it.

Spread out a piece of white paper on the big table, Lin Feng began to draw, and the plane gradually took shape on the white paper.

Leihuo Aero Engine Design Center.

Several design experts sat in Fang Anping's office, drinking tea and chatting about work.

"Mr. Fang, I'm not used to working so leisurely now. Many of the people below have gone on a trip with their families."

Fang Anping said, "Everyone has worked hard in designing and developing the LH165 turbofan engine. Anyone who wants to ask for leave will be approved, so that everyone can take a good rest. I guess there will be new research and development tasks in a short time."

Hearing this, everyone's eyes lit up.

"Really!"

Fang Anping said, "The military is discussing the new models that need to be designed and developed in the future. They are either stealth fighters or large military transport aircraft. I think there is a high probability that we will design and develop military transport aircraft."

Everyone is an expert, and of course knows that the LH165 turbofan engine is not suitable for powering a large military transport aircraft.

This is a small bypass ratio military turbofan engine, mainly used in supersonic cruise aircraft, such as fighter jets, and high-speed bombers, while large military transport aircraft generally fly at subsonic speeds, emphasizing the comprehensive utilization of fuel, often using fuel utilization Higher efficiency and more economical large bypass ratio turbofan engine.

"If it is really a design and development of a large military transport aircraft, that would be great!"

"Yes, in this case, our design task is to develop a matching engine for this transport aircraft."

"Mr. Fang, why don't you ask the boss instead of us, when will we have design and development tasks?"

Everyone is really not used to the sudden leisure.

Those who should rest should also rest, and the time for rest is enough. I even took my family to travel around the country. What everyone hopes most is to devote themselves to intense work and then design and develop new aero engines.

In other aero-engine design institutes, such a situation would basically not occur. A new engine still has many problems in the small-batch production stage, and various problems will even be exposed one after another.

But the design of the LH165 turbofan engine comes from the system, and everyone is just drawing from the gourd under Lin Feng's guidance. This engine is basically not in the stage of small batch production and manufacturing, even in the stage of trial production and test run of the prototype question.

No problems were exposed, and as design and development personnel, everyone basically had nothing to do.

As for design improvement and perfection, everyone seems to find that this engine seems to be very perfect, and there is basically no need for improvement.

Fang Anping is not used to being so leisurely. He also hopes to design and develop engines as much as possible in his career, instead of letting time pass in vain.

"Okay, if I have a chance, I will ask the boss and try to get us another new design and development task."

Lin Feng carefully drew the real color picture of this transport plane in his office. The painting was placed there horizontally. The real color picture drawn was like a huge photo, with a strong sense of three-dimensionality.

After a few days of work, several real color maps were drawn. In addition to the real color map of this large transport aircraft, there is also a real color map of this large bypass ratio turbofan engine.

This is a turbofan engine with a large bypass ratio. The diameter of the fan reaches 2.8 meters. It looks basically the same as the engine of a large civil airliner, but it looks more beautiful and more refined.

Its fuel efficiency is higher than that of civil large passenger aircraft engines, and its economic performance is better, which is one of the reasons why such a heavy aircraft can fly up to 15600 kilometers.

In other words, with the same weight of fuel, other people fly [-] kilometers, and using such an engine as power can increase the range by thousands of kilometers.

It not only has high fuel efficiency and first-class economic performance, but also has world-class safety and reliability, even noise and vibration.

Lin Feng thought to himself more than once, such an engine can be used not only as the power of a large military transport aircraft, but also as a power of a large civil aviation airliner, which is far better than the engines of Rolls-Royce, Pratt & Whitney and other companies.

Single thrust: 198 kN
Thrust-to-weight ratio: 10.8
The biggest advantage is low fuel consumption.It consumes much less fuel than any turbofan engine of its size, and it makes less noise!

In addition to saving fuel, it also has a series of advantages such as large thrust, high thrust-to-weight ratio, long service life, and high reliability.

It is indeed a turbofan engine designed by the system.

Lin Feng looked at the results of his work in the past few days with satisfaction. There are five real color pictures in total, including three pictures of this large transport aircraft from three different angles. In addition, there are two real picture pictures of this turbofan engine. Zhang, also from two different angles.

He was holding one of the real color pictures of the engine and looked at them with satisfaction when there was a knock on the door of the office. Lin Feng did not put down the color picture in his hand, but said loudly, "Come in, the door is unlocked."

It was Fang Anping who opened the door and entered.

Entrusted by everyone, he came here to inquire, but just as he came in, he saw the large real color picture in Lin Feng's hand, his eyes lit up immediately, and he walked over quickly.

"Boss, what kind of engine is this!"

There was a lot of excitement in his tone. As an expert in aero-engine design, he could tell at a glance that this turbofan engine with a large bypass ratio was unusual, but it was definitely a model he had never seen before.

Lin Feng put down the colored picture in his hand, "Take a look at this engine."

Fang Anping took it, then looked at it seriously, and after looking at it for a while, said, "Boss, is this the engine we will design and develop next?"

Lin Feng nodded, "Yes, this is the high bypass ratio turbofan engine we are going to design and develop, it will be the power of large military transport aircraft in the future, the military has officially decided, we will undertake a research and development task. "

Briefly explain the situation.

Fang Anping said in surprise, "Really, that's great. Everyone has long been looking forward to the new design and development task. Now it's good. The design task has really come."

Or a large military transport aircraft!
He likes this kind of design and development work!

"Boss, can you give me these two real color pictures, let me take them back for everyone to have a look, and let everyone know what the engine we need to design and develop next looks like."

Lin Feng nodded and said, "These two real color pictures can be given to you, but I have to conceive the specific design of this engine, the design technical outline, the general design drawing, including the design drawings of some key components. draw."

Everything is still the old rules!
It's not that Lin Feng is worried about Fang Anping's technical level, but that this engine is really good. If you don't make these things yourself, it will not only take a lot of time to design and develop them just by Fang Anping and the others. The engine is estimated to be world-class.

What Lin Feng needs is the world's top level high bypass ratio turbofan engine, not the world's first-class level, then everything should be done according to the old rules, which not only saves time, but also guarantees the quality.

"Boss, that's great!"

Fang Anping felt relieved. Of course, he knew Lin Feng's technology very well. With these things from the boss, plus the technical guidance of the design and development process, they would have no pressure.

Why didn't the design technical outline come out right away? It would be too shocking if it was done this way. Lin Feng excused that he needed time to conceive a good idea. After another half a month or a month, it would appear to be "normal". up.

After giving Fang Anping two real color pictures of this engine, Lin Feng roughly told him some "concepts" of this engine, such as what design features it has, how much thrust it has, and emphasized low fuel consumption, High reliability and security.

After hearing this, Fang Anping said in surprise, "In this case, this engine has a wide range of uses. It can be used as power for large aircraft flying at subsonic speeds, such as large bombers, large transport aircraft, and large passenger aircraft."

Lin Feng said with a smile, "Versatility is a great thing. I also hope that in the future, most of the large passenger planes in the world will use our engine as power."

After chatting with Lin Feng for a while, Fang Anping also had a rough outline of the high bypass ratio turbofan engine to be designed.

He took these two color pictures back to Leihuo Aero Engine Design Institute.

Several design experts came over immediately, gathered together to look at the two color pictures with great interest, and listened to Fang Anping's introduction and explanation.

what!
The thrust is so large, reaching 198 kN!

The thrust-to-weight ratio is so high that it has reached a high thrust-to-weight ratio of 10.8!
Everyone is an expert in the field of aero-engine design, and they are very clear about what this means. Undoubtedly, this is the world's top-level turbofan engine with a large bypass ratio.

"The boss is really courageous. If you want to do it, you can do it at the top of the world!"

"I'm a little eager to try, and I hope to start the specific design work sooner!"

"If this engine is successfully designed, it will add another member to our company's aero-engine family."

"."

The news gradually spread throughout Leihuo Aviation Engine Design Center. Many design backbones knew about this matter and began to tell the designers below to take care that new design tasks would be ushered in soon.

in the office.

Lin Feng was still not in a hurry to compile the design technical outline himself, but spread out the three color drawings of the transport aircraft that he had drawn before, mainly to see if there was any room for modification and polishing.

After reading it, I feel very satisfied, and there is basically no need to modify it.

"Boom, boom, boom!"

There was a knock on the door first outside the office, and then Zhao Mingzhi opened the door and came in, "Boss, you are looking for me."

As soon as he received Lin Feng's call, he rushed over. On the way, he wondered what the boss had asked him to come over. Could it be the stealth strategic bomber, but he quickly denied it.

He heard some news that the military seemed to be designing and developing a large military transport aircraft. It seemed that the boss had personally drawn a color map of the turbofan engine of this large transport aircraft.

Lin Feng beckoned, "Come here, take a look at these color pictures, how about our plane."

Zhao Mingzhi walked over quickly, and seeing these colored pictures spread out on the big table, his heart jumped uncontrollably. The rumors were indeed true, the boss even drew the colored pictures of this large military transport plane .

"Boss, is this the large military transport aircraft we are going to design and develop!"

Lin Feng said, "The military has already decided that we will undertake the design and development task of this large military transport aircraft. These days, I have been thinking about what this transport aircraft will look like, so, according to the idea in my mind, I designed it The shape is drawn."

Zhao Mingzhi looked at these color pictures with great interest, and then praised, "The design is really beautiful. This is completely as good-looking as ever. The appearance alone can attract the attention of many people."

Lin Feng knew exactly what this transport plane looked like.

It's just that I can't talk to Zhao Mingzhi in detail now, but a brief introduction is still possible, so I briefly introduced this transport plane based on these three color pictures, all of which are excuses to explain the concept of this transport plane in my mind.

Zhao Mingzhi was overwhelmed with admiration!

As expected of the boss!

From the very beginning, this aircraft was positioned as the top in the world, completely surpassing the C-17 Globemaster transport aircraft in the beautiful country.

Zhao Mingzhi even thought in his heart that the beautiful country spent a lot of manpower and material resources, and it took more than ten years to successfully develop the C-17 Globemaster. This transport plane has not been officially in service for a few years.

If you let them know that in the next two or three years, this large transport aircraft of Leihuo Technology Industrial Group will roll off the production line and surpass their Globemaster transport aircraft in an all-round way, I don't know how they will feel.

Being surpassed, the feeling is probably not good.

Lin Feng didn't care about this, and said loudly, "I'll take these three color pictures back for you, print a batch, and hang a few on the walls of each design room, so that everyone can understand the large transport aircraft we are going to design next. What's it like."

[-] words, I implore all readers to come with a monthly ticket, or a recommendation ticket to support.
