Although the maximum voyage is still a little bit longer than the standard threshold of 5,000 kilometers for a trunk airliner, the 3,500 kilometers voyage is enough for domestic use.

What's more, the Air Force is right that the 220-300 senior government aircraft is a special-purpose aircraft for domestic leaders of the upper-level leaders.

No way, the TM-9 advanced government jet and the special-purpose aircraft modified by the Yun-15plus produced by Ascendas in China before are too small in size or range, so that if two leaders want to go out together, an aircraft is simply Can't hold all the entourage.

In addition, the internal comfort is average and the range is limited. By the mid-1990s, it was no longer suitable for the travel needs of the upper-level leaders. It is imperative to install a larger and better dedicated machine.

It is naturally easy to choose foreign brands such as Boeing and Airbus to modify passenger planes, but the upper-level leaders feel that since the old leaders in the 1980s have adopted domestic models as special planes, they should continue this tradition.

It’s a different matter to visit foreign countries because of voyage problems and domestic production is not possible. Domestic inspections do not involve too many external factors, which can slightly reduce some requirements. Therefore, the upper-level leaders still tend to choose from several mature models in China. A new model was selected from among them.

Since the upper-level leaders meant this, the Air Force must take it seriously. So China took off because it had previous mature experience in producing special aircraft for chief executives, and it also maintained the production structure of some civilian airliners. It belongs to a relatively outstanding domestic commercial airliner manufacturer. Therefore, the Air Force handed this order to China Ascendas to complete.

Of course, the order to China Ascendas is to China Ascendas, but because it is a military project, there are high-level leaders involved, so there is no shortage of confidential projects.

China's take-off is also due to various reasons and did not make too many innovations in this project, but in accordance with the requirements of the Air Force in the —220 lengthened and widened fuselage, using more mature and reliable aluminum-lithium alloy as the main structural material, matched with The carbon fiber composite materials of the wing and tail, and the WD-68ML-neo...

However, although it has not incorporated too many super new technologies, because of the needs of the Air Force, China Ascendas still uses its own super technological integration capabilities as much as possible and adopts mature technologies to meet the requirements of the Air Force.

For example, noise control indicators. As the upper-level leaders generally need urgent work when taking special planes, they have extremely strict requirements on the noise in the cabin. In order to solve this problem, China Ascendas not only uses aramid fiber honeycomb plus aluminum lithium The honeycomb composite material of the alloy backplane is used as the skin of the machine body, which can greatly reduce the interference of noise to the cabin while insulating and moisture-proof.

Secondly, improve the efficiency of the engine, thereby reducing the engine, the biggest source of noise.

The last is to increase the flight altitude, so that the 220-300 advanced government aircraft most of the time fly in the stratosphere above 10,000 meters, not only the air resistance is small and the speed is faster, but the flight is more stable and comfortable.

After such a series of control measures, the 220-300 advanced government aircraft has become the best noise control aircraft in China's Ascendas so far. The noise during low-altitude flight is 83.4 decibels; the noise during approach and landing is 93.4 decibels; the noise of lateral detection is 89.3 decibel.

These three are the biggest noises of airplanes. At best, they are only the sound of chainsaw operation. Compared with other similar models, they are reduced by at least 30%. This is the case on the outside. It can be seen to what extent the noise control inside the cabin will be.

In the words of a major leader who took the 220-300 senior government jet to investigate the local area for the first time: "I fell asleep without knowing it in my seat. There is no way. This plane is really not noisy. It is better than me. The house is still quiet!"

Of course, these are related to the secrets of the development of the 220-300 advanced government aircraft. The navy chief who is telling the crowd on the scene is not clear. He was only fortunate to accompany a major leader once during the inspection. The 220-300 advanced Government aircraft, learned the general situation of this aircraft from a leader of the Air Force accompanying it.

As for the specific Air Force leader, it is not very clear, because a certain Air Force department has purchased a total of 6 planes, and 4 of them are domestic special planes that serve as upper-level leaders. At least one of them must be kept on standby 24 hours a day.

The other two are strategic command aircraft with a complete set of advanced military communication systems and command and control systems added to the 220-300 advanced government aircraft.

Different from the prototype of the previous strategic command aircraft modified with the Yun-15plus, which can only issue simple commands, the new strategic command aircraft modified from the 220-300 advanced government aircraft can not only transmit important information such as images, but also Incorporating the nuclear counterattack mode, it has become the most modernized electronic combat aircraft in the country.

However, whether it is a special plane or a strategic command plane, due to its particularity, in addition to the extremely high level of confidentiality, the price is also very, very moving.

The unit price of 4-220-300 advanced government aircraft is 550 million yuan; the unit price of 2 modified new strategic command aircraft is as high as 1.08 billion yuan.

So I originally thought that the 220-300 advanced government jet was pretty good, and I wanted to equip the navy with a few naval chiefs who supported the facade. Then he immediately retreated, and then began to complain about China’s take-off with the leader of the Air Force. That person named Zhuang Jianye is really black-hearted.

So even at this moment, the chief of the Navy did not forget to say in terms of price: "Blessed are the big guys, let alone the chief's special machine, just sit on it with a unit price of 550 million. It’s not a loss, so this time China’s take-off is still costly, and it’s very sincere to use such a good plane to pick it up."

After that, he was the first to board the spiral staircase, and couldn't wait to walk into the cabin.

When everyone else listened, what? This aircraft in front of you is actually a special-purpose aircraft specially built for upper-level leaders? Good guy, the car of the upper-level leader is fortunate enough to experience it today?

Thinking of this, many gray-haired experts and leaders looked very excited. Com people who have come over this age can be said to be familiar with the Trident aircraft back then, and they have a special liking for this kind of thing that has been tainted by the leadership.

Red flag cars, Moutai, Zhonghua Tobacco, Chinese tunic... This is not the case.

If you can wish to get back one yourself, then the predecessors will install all kinds of arrogant Big 13:

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

It’s just that this 550 million one is really...

"Dear leaders and chiefs, this-220-200, our China Ascendas is currently on sale. 250 million yuan per aircraft, which is equivalent to 31.25 million U.S. dollars. It is only at the level of an ordinary foreign 50-seat regional airliner, but our China takes off. In order to meet the needs of different units, Chairman Zhuang Jianye said that China Ascendas is spending 10 million U.S. dollars per rack this time, and it has to make friends with each unit and sell it at 250 million yuan~!"

Just when everyone hesitated that the price was too expensive and it was really difficult to get started, Tang Lili suddenly spoke, and loud and loud words spread all over the sides of the suspension ladder. The navy chief who was almost at the door of the cabin heard the words and turned back immediately: "Sell for 250 million. ,you sure?"
