Chapter 3021: Expensive

This episode has passed, and there are still more crowds watching. However, although this aircraft has advanced performance, the price is too high after all. Therefore, many potential customers are still staying on the sidelines. This kind of aircraft is also being built, and the price is two to three thousand, but Han Guo has already risen to 100 million. Therefore, most potential customers still feel that this gadget is too expensive and not worth it.
Qin Guan also understands this kind of psychology. Now that they are too expensive, then wait for the F35 of the Yingguoren. When the F35 of the Yingguoren comes out, the price is definitely higher than that of his own. At that time, it depends on what they do. At that time, our F-31 has already bloomed all over the place, and it is still being used for continuous improvement, and the performance is naturally more mature.
"Excuse me, what's the matter with this integrated avionics system? The introduction is very simple." At this moment, someone below issued a question.
Some of them held the propaganda brochures, and some had opened them. After all, the fighter planes on the booth were always covered, so that people could not see anything, a mysterious look, and they were looking through it. When they were in the brochure, they saw this term, integrated avionics system.
"We know that the electronic systems of the current fighters are all independent. For example, airborne radars are only responsible for searching for targets. VHF communications are only responsible for communications, and the identification of friend or foe is only responsible for identification of foe or foe. And our integrated avionics system is to integrate all the avionics systems. If we compare, an aircraft will need more than 60 antennas. In our aircraft, it has been integrated, and only left More than a dozen antennas." Since someone has asked, it is natural to introduce them to the advanced technology of Han, especially the advanced electronic technology.
Speaking of the fourth-generation aircraft, a variety of performances make people talk about it, such as its stealth capability, supersonic cruise capability, super maneuverability brought by vector nozzles, etc., but they are only ignored by most people. , Is its advanced avionics performance, in fact, this is a key equipment that can significantly improve its combat performance.
"Specifically, it is integrated radio frequency and integrated sensor. For example, our radar antenna is an integrated radio frequency. It can not only send out radar signals, search for enemy aircraft, but also send out identification friend or friend signals, and even send out communication signals. After the integration of avionics, the required data throughput is greatly increased. We estimate that the data transmission on the aircraft will require at least 400 megabits per second, or even higher, so we can no longer use the 1553B data bus. Yes, we use optical fiber transmission. In this way, electromagnetic interference can also be avoided."
The integrated avionics system of the fourth-generation aircraft is almost brand new. The 1553B data bus led by the Eagles is still the standard configuration of advanced fighters. However, with this data bus, the signal transmission speed is not fast enough. Only optical fibers are used. Yes, so this aircraft is already a fighter using optical fiber transmission.
Apart from other things, in terms of electronic systems, Han is definitely the role of Big Brother.
And this really caused the people on the scene to boil. Han said that their fighters are expensive, which naturally makes sense. People's equipment is revolutionary.
Everyone was sighing, and Qin Guan, already in the sigh of everyone, left the booth here, continued to inspect other booths, and soon came to the front of the booth of Huating Airlines.
At this time, there is also a sea of ​​people here. After all, behind the booth here, surrounded by isolation lines, it is a big plane! This large passenger plane occupies a large area. At this time, many people are using cameras and snapping photos of it.
Of course, if you look carefully, you can find that this is not a real airplane, but a model built with a one-to-one ratio. Generally speaking, the airliner model can be scaled down, but after reducing the scale, There is no such intuitive impression.
As for why it is not a real airplane, of course it is because it has just entered the research and development stage, and it has not yet begun to manufacture prototypes. It is just a model.
Building airplanes and building wooden models is almost always a tradition. Now, with such a big guy in front of his eyes, the visual impact is very conspicuous.
In front of the platform, Lisa stood on the platform herself, welcoming countless people's questions.
"Excuse me, what class of aircraft is this?"
"It is a dual-aisle wide-body airliner. When all of them are in economy class, the seats can reach close to 300 seats. At the same time, the range under full load will reach 12,000 kilometers. We believe that this type of aircraft can better adapt to the market and bring more considerable economic benefits to various airlines."
The civil aviation market is completely a capital market for the survival of the fittest. For the operation of civil aviation, economy always comes first. Airliners developed by airlines must also follow this principle. Otherwise, they will definitely compete in the market. Failed.
Now, Lisa turned to the back, and the model of the large passenger plane pointed to the past: "We designed a twin-engine structure for it. Compared with the current four-engine layout, this twin-engine aircraft has lower fuel consumption. , The maintenance volume is smaller, and at the same time, it is more safe and reliable."
"Excuse me, what engine does it use?" someone asked.
After all, the performance of a passenger plane mainly depends on the performance of its engines. This kind of large passenger plane is generally arranged with four engines. Now, the other party actually only uses two engines. The two engines are naturally the top priority. Although Han Dynasty has advanced fighter engines, it does not mean that they also have advanced passenger aircraft engines.
It takes a lot of effort to develop a passenger aircraft engine. Do Han people have this technology?
Everyone is looking at Lisa, this young and beautiful woman, the recent experience is also embarrassing.
"It has several alternative engines. We can equip it with different engines according to the needs of customers." Lisa said: "For example, we have self-developed engines and a joint venture with Motor Sic. For the jointly-developed engine, we can also purchase Rolls-Royce and other products. This is completely market-oriented. By the way, Motorsic also has a booth today. You can also visit the booth next to us for an interview."
