On May 9, the Ark 600 passenger aircraft entered the design review.

After a total of three days, the Ark 600 passenger aircraft successfully passed the review of the expert group, and in the near future, the Ark 600 passenger aircraft will obtain the design certificate and will also enter the comprehensive trial production stage of parts.

On 12 May, the military officially issued the task of developing a long-range strategic bomber, and Li Tianfeng personally received the task book from General Wei in Beijing.

General Wei's office.

Li Tianfeng and Zhang Haiping were all there, and Mr. Wei had a straight face, and personally handed over the development task book covered with a bright red seal to Li Tianfeng, who solemnly took the task book and carefully put it away.

Then, Li Tianfeng handed over the design technical outline of this long-range strategic bomber to Mr. Wei, who was a little surprised when he received the design technical outline.

Mr. Wei said happily: "Tianfeng, I didn't think about it, you moved so quickly, and the design technical outline has been completed, which is good." ”

Li Tianfeng said: "We are ready for everything, only the east wind is owed, we started the design and development of this long-range strategic bomber early, the design scheme is basically mature, and the design technical outline was completed last month, and passed the internal review of our Tianfeng Technology Company." ”

The design technical outline, under the guidance of Li Tianfeng, was completed by Lei Yong and led by the design team, which was revised and improved several times, and successfully passed the internal review of Tianfeng Technology Company at the end of April.

In fact, it is far more than that, considering that it is a sure thing for the military to develop a new long-range strategic bomber, Li Tianfeng took precautions, not only did he get a good outline of the design technology, but he also drew a large number of design sketches himself.

This bomber is very clear in Li Tianfeng's mind, and these design sketches are naturally very easy to draw. With his own efforts, in more than a month, there are dozens of design sketches, not only structural design sketches, shape and aerodynamic design sketches, but also a series of other design sketches.

Mr. Wei said: "Tianfeng." Looking at this, you are confident, can you introduce me to our future long-range strategic bomber. ”

Li Tianfeng said: "Yes, there is no problem. ”

After speaking, Li Tianfeng took out an A2-sized color picture from his bag and spread it out in front of Mr. Wei.

"This is our bomber, so beautiful!"

The bomber has a blunt triangle in shape. The hybrid design structure of wings and fuselage is full of streamlined beauty, and the bare appearance immediately attracted Mr. Wei's eyes.

Pretty!

It's beautiful!

Mr. Wei said: "Tianfeng, I didn't think about it, our future bomber is so beautiful, and such a shape design should be famous." ”

Li Tianfeng nodded and said, "Mr. Wei." This is a 'hybrid wing and fuselage structure' design, a very good and advanced form factor design. Our 'Black Ghost' UAV is designed in this way, but the 'Black Ghost' UAV can only be regarded as the first generation of 'wing and fuselage hybrid structure', while our long-range bomber belongs to the second generation of 'wing and fuselage hybrid structure', and the Ark 600 passenger aircraft has a more advanced shape design. ”

Hearing that the appearance design was more advanced, Mr. Wei looked at Li Tianfeng happily.

Li Tianfeng continued: "Such an appearance design. The lifting ratio is greatly increased, the air resistance is greatly reduced, that is, the fuel consumption will be greatly reduced when flying, and it will have an ultra-long range. ”

Mr. Wei said: "Tianfeng, the appearance is so beautiful. So advanced, how about its stealth performance? ”

Mr. Wei knows that this is a stealth bomber, and Mr. Wei has always hoped that this bomber needs to have very good stealth performance.

However, Li Tianfeng's answer reassured Mr. Wei.

Li Tianfeng said: "Mr. Wei, our bomber is not only beautiful in appearance, but also has excellent stealth performance, and its stealth performance is still above the 'Black Ghost' drone. ”

On top of the "Black Ghost" drone!

No way!

Even Zhang Haiping, who had not spoken, said: "Mr. Li, no!" Actually better than the stealth performance of the 'Black Ghost' drone? ”

You know, the stealth performance of the "Black Ghost" UAV is very good, and it can even frequent the US mainland to take off, if the stealth performance of this long-range bomber is still above the "Black Ghost" UAV, it will be a bit against the sky.

Even Mr. Wei looked at Li Tianfeng, waiting for Li Tianfeng to answer.

Li Tianfeng said affirmatively: "That's right, the stealth performance of our bomber is indeed above the 'Black Ghost' drone, and I will often go around the world in the future, even if I go to Lao Mei's home, there is no problem." ”

The stealth performance is so good!

Li Tianfeng said: "Its main feature is low detectability, which is commonly known as stealth ability. It can safely pass through tight air defenses and attack. In addition, stealth is not only limited to radar detection, but also includes reducing different signals such as infrared, visible light and noise, so as to minimize the possibility of detection and locking. ”

Mr. Wei said happily: "Tianfeng, great, I didn't think about it, the stealth performance of our bomber is so good, in addition to the excellent stealth performance, what about other aspects?" ”

Li Tianfeng said: "Our long-range strategic bomber, although it is only a subsonic bomber, it is an all-rounder, not only can act as a strategic bomber, but also can be fully conventional bomber. ”

Mr. Wei said with satisfaction: "The all-rounder is good, I like the all-rounder." ”

Li Tianfeng said: "It is not only all-round, but also all-weather, not affected by the weather, whether it is day or night, whether it is rain or wind, as long as there is a need, it can take off from the airport and fly to all parts of the world without being affected." ”

Li Tianfeng introduced it in detail, and even introduced the design parameters of this bomber in detail.

The design parameters are as follows:

Length: 25 meters.

Wingspan: 58 meters.

Wing area: 785 square meters.

Empty weight: 36000 kg.

Bomb load: 38000 kg.

Normal take-off weight: 150 tons.

Maximum take-off weight: 165 tons.

Power: Two turbofan 26 large bypass ratio engines.

Maximum speed: Mach 0.98.

Cruising speed: Mach 0.8.

Range: 20,000 km.

Practical ceiling: 16000 meters.

……

After listening carefully to Li Tianfeng's introduction, Mr. Wei asked: "Tianfeng, the American B2 bomber is known as the most advanced bomber in the world today, how is the American B2 compared with our bomber?" ”

Li Tianfeng smiled.

After Li Tianfeng finished laughing, he said: "Mr. Wei, the American B2 bomber can only be regarded as a scum in front of our bomber. ”

It can only be regarded as a scumbag!

Even if Mr. Wei is in a high position and has always been able to be calm, but at this moment, his face is obviously a little excited, "Tianfeng, really?" ”

Li Tianfeng said confidently: "It's true, the Americans' B2 bomber is indeed far behind our bomber. ”

Both Mr. Wei and Zhang Haiping know that Li Tianfeng is not a person who talks big, nor is he a person who brags, since Li Tianfeng said so, it must be true.

In fact, it can be seen from the design technical outline that whether it is range, bomb load, stealth, and other aspects, it can throw off the B2 bomber several streets.

For example, bomb load is often one of the most important indicators to measure a bomber, the maximum bomb load of the B2 bomber in the United States is 18 tons, 16 rotating pylons, and our bomber has a bomb load of 38 tons and 32 rotating pylons.

Our bomber can carry hundreds of bombs at a time, even with a 750-pound cluster bomb, for a total of 72 bombs.

Needless to say, the American B2 bomber has a maximum range of 12,000 km, while ours has a maximum range of 20,000 km and can carry out a global strike even without in-flight refueling.

The bomber was very advanced, and Mr. Wei was very happy and satisfied.

However, Mr. Wei did not lose his calm, and after listening to Li Tianfeng's introduction, Mr. Wei asked about the cost of this bomber.

Although the performance is good, it is also very good, but if the cost is too high, it is a pity, as the Minister of Defense, naturally very concerned about the cost.

The cost of the American B2 bomber is high, and the cost of the American one is as high as 2.4 billion US dollars, US dollars! If converted into RMB, each aircraft would have been more than 10 billion yuan, and the cost of a Nimitz-class aircraft carrier would be about 4.5 billion US dollars.

So, Mr. Wei said with concern: "Tianfeng, you just introduced so much, I know that this bomber is very advanced, very good, it must be one of the most advanced bombers in the world, how about the cost of such a bomber?" ”

Zhang Haiping also said: "Mr. Li, the cost can't be too high, otherwise, our military can't afford it." ”

Li Tianfeng had obviously considered the cost of this bomber for a long time, and Li Tianfeng smiled lightly: "Mr. Wei, Minister Zhang, don't worry, the cost of this bomber will not exceed 1 billion yuan." ”

Mr. Wei's heart was light, "Tianfeng, the cost of a billion US dollars is not expensive, less than half of the cost of the American B2." ”

Zhang Haiping also said: "Mr. Li, the cost of 1 billion US dollars is within our affordability, and according to our financial resources, we should be able to install 30 or 50 aircraft." ”

The Americans' B2 bombers cost $2.4 billion, a high cost, and even the powerful United States has only installed more than 20 of them, each of which is a baby bump.

Mr. Wei and Zhang Haiping, both of them felt light, obviously, both of them accepted the price, but Li Tianfeng smiled and said: "Mr. Wei, Minister Zhang, do you think it is the cost of 1 billion US dollars." ”

The two said in unison: "Isn't it?" ”

Li Tianfeng said: "No, no, you are all wrong, I said 1 billion yuan, which is less than 150 million US dollars when converted into US dollars." ”

No way!

1 billion RMB!

$150 million!
