Although the maximum range is still some distance from the standard threshold of 5,000 kilometers for mainline passenger aircraft, a range of 3,500 kilometers is enough for domestic use.
What's more, the Air Force considers the fcnb-220-300 high-level government aircraft to be the exclusive aircraft for domestic chiefs of higher-level leaders.
There is no way. The TM-9 high-end government aircraft and the Y-15plus modified special aircraft produced by China Tengfei were too small in terms of size and range. If the two leaders wanted to go out together, one aircraft would not be enough. There is no room for all the entourage.
Coupled with the average internal comfort and limited range, by the mid-1990s it was no longer suitable for the travel needs of upper-level leaders, so it was imperative to upgrade to a larger and better special-purpose aircraft.
It is naturally easy to modify passenger aircraft of foreign brands such as Boeing and Airbus, but the upper-level leaders feel that since the old leaders in the 1980s have already adopted domestic models as special aircraft, this tradition should be continued.
It¡¯s a different matter when it comes to overseas visits that cannot be manufactured domestically due to flight issues. Domestic inspections can slightly lower the requirements because they don¡¯t involve too many external factors. Therefore, the upper-level leaders still tend to choose from several mature domestic models. Choose a new model.
Since the upper-level leaders meant this, the Air Force naturally had to implement it conscientiously. Therefore, China Tengfei has mature experience in producing special aircraft for commanders, and it also maintains part of the production structure of civilian passenger aircraft. It is one of the outstanding civilian passenger aircraft manufacturers in China. , so the Air Force handed over this order to China Tengfei to complete.
Of course, if the order is given to China Tengfei, it is given to China Tengfei, but because it is a military project and involves high-level leaders, there are no missing items that should be kept confidential.
China Tengfei also did not make too many innovations in this project due to various reasons. It only used the more mature and reliable aluminum-lithium alloy as the main structural material in the fcnb-220's lengthened and widened fuselage in accordance with the requirements of the Air Force. The carbon fiber composite materials of the wings and tail are developed from China's most mature wd-68ml turbofan engine wd-68ml-neo
However, although it has not incorporated too many super new technologies, due to the needs raised by the Air Force, China Tengfei still tries its best to use its own super technology integration capabilities and adopt mature technologies to meet the requirements of the Air Force.
Take the noise control index for example. Since upper-level leaders generally need urgent processing work when taking special planes, they have extremely strict requirements for 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 back panel serves as the skin of the aircraft body, which not only insulates heat and moisture, but also greatly reduces noise interference to the cabin.
Secondly, it improves the efficiency of the engine, thereby reducing the engine, the largest source of noise.
The last step is to increase the flight altitude so that the fcnb-220-300 advanced government aircraft flies in the stratosphere above 10,000 meters most of the time. Not only does it have low air resistance and is faster, but it also flies more smoothly and comfortably.
After such a series of control measures, the fcnb-220-300 advanced government aircraft has become the aircraft with the best noise control so far in China Takeoff. Its noise when flying at low altitude is 83.4 decibels; the noise when approaching and landing is 93.4 decibels; the lateral detection noise 89.3 decibels.
????????These three types of noise are the biggest in the aircraft. At best, they are just the sound of a chainsaw running. Compared with other similar models, they are at least 30% lower. This is true for the outside. This shows how good the noise control inside the cabin will be.
In the words of a senior leader who took the fcnb-220-300 high-level government aircraft for local research for the first time: "I fell asleep in my seat without knowing it. I couldn't help it. This plane is really not noisy. My house is still quiet!¡±
Of course, these secrets about the development of the fcnb-220-300 high-level government aircraft were not clear to the navy chief who was telling the crowd at the scene. He was only lucky enough to fly on the fcnb-220- once during an inspection with a certain leader. 300 high-level government aircraft. I learned the general situation of this aircraft from a leader of the accompanying Air Force.
As for the specific Air Force leader, it is not clear, because a certain Air Force department purchased a total of 6 aircraft, 4 of which are domestic special aircraft for upper-level leaders, and at least one must be kept on standby 24 hours a day.
The other two are strategic command aircraft based on the fcnb-220-300 advanced government aircraft and equipped with a complete set of advanced military communication systems and command and control systems.
Different from the prototype of the previous strategic command aircraft modified by the Y-15plus, which could only issue simple commands, this new strategic command aircraft modified from the fcnb-220-300 advanced government aircraft can not only transmit important information such as images in two directions, but also It also incorporates a nuclear counterattack mode, making it the most modern electronic combat aircraft in the country.
However, whether it is a special plane or a strategicDue to its special nature, in addition to the extremely high level of confidentiality, the price is also very, very impressive.
The unit price of 4 fcnb-220-300 high-end government aircraft reaches 550 million yuan; the unit price of 2 modified new strategic command aircraft is as high as 1.08 billion yuan.
So much so that the Navy chief, who originally thought that the fcnb-220-300 high-end government aircraft was quite good, and wanted to equip the Navy with a few to support its appearance, immediately backed down, and then began to complain about China's take-off and loss of conscience along with the Air Force leader. , that man named Zhuang Jianye is really evil.
So much so that even at this moment, the chief of the Navy did not forget to sigh about the price: "You guys are still lucky. Not to mention that it is a special machine for the chief, with a unit price of 550 million, I can sit on it. It¡¯s not a loss, so China Takeoff has spent a lot of money this time, and using such a good plane to pick us up is very sincere.¡±
With that said, he was the first to board the spiral staircase and couldn't wait to walk to the cabin.
When other people heard it, what? The aircraft in front of me is actually a chief-only aircraft specially built for upper-level leaders? Good guy, am I lucky enough to experience the car of a senior leader today?
Thinking of this, many gray-haired experts and leaders looked very excited. People who came from their generation were familiar with the Trident aircraft and had a special affection for this kind of thing that had the glory of a big leader. Solitary.
??Hongqi cars, Maotai liquor, Chinese cigarettes, Chinese tunic suits nothing better than this.
If I can, I wish I could get one back, and then show off all kinds of arrogance and arrogance to others:
Look, I also own the big leader¡¯s car!
It¡¯s just that this 550 million one is really
"Dear leaders and chiefs, China Ascendas is currently offering a discount on this fcnb-220-200, priced at 250 million yuan per unit, which is only 31.25 million yuan converted into US dollars. It is only at the level of ordinary foreign 50-seat regional passenger aircraft, but our China In order to meet the needs of different units, Ascendas Chairman Zhuang Jianye said that China Ascendas will spend 10 million US dollars per unit this time, and it will also make friends with each unit and sell it for 250 million yuan~!"
Just when everyone was hesitating that the price was too expensive and it was really difficult to buy, Tang Lili suddenly spoke, and the loud words spread on both sides of the hanging ladder. The navy chief who was already approaching the cabin door immediately turned around when he heard the words: "Sell it for 250 million. ,you sure?"
