Chapter 1437

Although there is still some distance on the maximum range compared with the standard threshold of 5000 km, 3500 km is enough for domestic use.

What's more, the air force's fcnb-220-300 high-level government aircraft is the domestic chief's special aircraft of the top leaders.

There's no way. The tm-9 high-level government aircraft and the yun-15plus refitted special aircraft produced by China's take-off are so small in size and range that if the two leaders want to go out together, one plane can't hold all the accompanying personnel.

In addition, the internal comfort is general and the voyage is limited. By the mid-1990s, it was not suitable for the travel needs of the top leaders, so it was imperative to replace it with bigger and better special aircraft.

If you choose Boeing, Airbus and other foreign brands of aircraft refitting is naturally easy, but the top leaders feel that since the old leaders in the 1980s have adopted domestic aircraft as special aircraft, it should continue this tradition.

When visiting abroad, because of the problem of voyage, it can't be manufactured at home, which is another matter. Because domestic inspection doesn't involve too many external factors, it can slightly reduce the requirements, so the top leaders still tend to choose a new model from several mature models in China.

Since this is what the top leaders mean, the air force naturally has to seriously implement it. Therefore, because China Tengfei has the mature experience in producing special aircraft for the chief executive, and it still maintains the production structure of some civil aircraft, it belongs to an excellent civil aircraft manufacturer in China. Therefore, the air force handed this order to China Tengfei to complete.

Of course, orders to China take off are given to China take off, but because it is a military project and involves the top leaders, there are no less confidential projects.

For various reasons, China's take-off did not make much innovation in this project. It just used more mature and reliable aluminum lithium alloy as the main structural material in the lengthened and widened fuselage of fcnb-220 in accordance with the requirements of the air force, and carbon fiber composite materials for the wing and tail, And wd-68ml Neo, developed from the most mature wd-68ml turbofan engine in China

However, although it did not integrate too many super new technologies, due to the requirements of the air force, China's take-off still made the best use of its super technology integration capability and adopted mature technologies to meet the requirements of the air force.

For example, the noise control index, as the top leaders generally need to deal with the urgent work when they take the special plane, so they have extremely strict requirements on the noise in the engine room. In order to solve this problem, China Tengfei not only uses the honeycomb composite material of aramid fiber honeycomb and aluminum lithium alloy back plate as the body skin, At the same time, it can greatly reduce the noise interference to the engine room.

Secondly, improve the efficiency of the engine, so as to reduce the engine, the biggest source of noise.

Finally, it is necessary to raise the flight altitude, so that the fcnb-220-300 advanced government aircraft can fly more than 10000 meters in the stratosphere most of the time, not only with low air resistance and faster speed, but also with more stable and comfortable flight.

With such a series of control measures, fcnb-220-300 advanced government aircraft has become one of the best noise control aircraft in China's take-off so far, with a noise of 83.4 dB when flying at low altitude; The noise of landing is 93.4 dB; The lateral detection noise is 89.3 dB.

These three kinds of noise are the biggest noise of aircraft. At most, they are the sound of electric saw running. Compared with other similar models, they are reduced by at least 30%. This is true for the outside. It can be seen how much noise control inside the cabin will be.

In the words of a big leader who took fcnb-220-300 high-level government plane to local research for the first time: "I fell asleep unconsciously in my seat. I can't help it. This plane is really quiet and quieter than my home!"

Of course, these secrets about the development of the fcnb-220-300 high-level government aircraft are not clear to the naval chief who is talking to a group of people on the scene. He was only fortunate enough to accompany a senior leader on an inspection tour when he took a fcnb-220-300 high-level government aircraft and learned about the general situation of the aircraft from a leader of the air force accompanying him.

As for the specific leader of the air force, it is not very clear, because a certain air force department has purchased a total of six planes, four of which are domestic special planes for the top leaders, and they have to keep at least one 24-hour standby every day.

The other two are strategic command aircrafts equipped with a complete set of advanced military communication system and command and control system on the basis of fcnb-220-300 advanced government affairs aircrafts.

Unlike the original strategic command plane modified by yun-15plus, which can only issue simple commands, the new strategic command plane modified by fcnb-220-300 not only can transmit images and other important information in two directions, but also integrates the nuclear counterattack mode, making it the most modernized electronic combat plane in China.

However, both the special plane and the strategic command plane, due to their particularity, in addition to the extremely high level of confidentiality, the price is also very touching.

The unit price of four fcnb-220-300 high-level government machines will reach 550 million yuan; The unit price of the two refitted new strategic command planes is as high as 1.08 billion yuan.

Utterly devoid of conscience, the FCNB - 220-300 senior government official was also very good. He also wanted to make complaints about the Navy's head of the navy who had been supporting the front door. He began to play the retreat drum with the leader of the air force. Then he began to take up the air in China with the leader of the air force.

Even at this moment, the head of the Navy did not forget to sigh on the price: "the big guy is still blessed. Let's not say it's the special aircraft for the head, but it's not a loss to sit on it with the unit price of 550 million. So this time, China's take-off is still at a cost. It's very sincere to use such a good aircraft to pick it up."

Then he was the first to climb the spiral ladder and couldn't wait to go to the engine room.

When the others listen, what? In front of this plane is actually for the top leadership to build a special aircraft? Good guy, I'm lucky to have a ride with the top leaders today?

Thinking of this, many gray haired experts and leaders are very excited. People in their age are familiar with Trident aircraft, and they have a special preference for this kind of thing with great leadership light.

Red flag car, Maotai liquor, Zhonghua tobacco, ZhongShanZhuang, etc.

If you can, you can't wait to get one back, and then you'll put on all kinds of arrogant big 13:

Look, I have a big leader's car, too!

But this 550 million one is really

"Dear leaders and heads, this fcnb-220-200 is currently on sale in China. It costs 250 million RMB per plane, which is equivalent to 31.25 million US dollars. It's just the level of an ordinary 50 seat regional airliner in foreign countries. However, in order to meet the needs of different units, Zhuang Jianye, the chairman of China take off, said that China take off is putting together 10 million US dollars for each plane, We also need to make friends with all units and have a sale of 250 million yuan ~! "

Just when everyone hesitated that the price was too expensive and it was really difficult to start with, Tang Lili suddenly opened her mouth, and the loud words spread all over the two sides of the ladder. The Navy chief who was close to the hatch immediately turned back after hearing the words: "250 million will be sold, are you sure?"
