Chapter 801

This is just the trunk airliner market, and the demand for larger regional airliners and business airplanes is even greater.

Among other things, the main reason why the tm-9 series of small business aircraft developed and produced by Tengfei group has been unable to open the international market is that the airworthiness certificates of Europe and the United States have not been applied for.

Of course, most of the factors are troublesome, but their own shortcomings are also the main reason why they can not break the shackles. Take the navigation system for example, business aircraft pay more attention to safety and privacy than ordinary civil aircraft.

However, when Tengfei group developed tm-9, only the old inertial navigation system with mechanical gyroscope as the core could be provided in China.

At that time, Tengfei group did not consider importing the most advanced inertial navigation system with laser gyroscope as the core. The problem was that the foreign price was too expensive, and the entry-level one would cost US $1.8 million.

That's enough to buy a matching version of the tm-9 business jet.

If that's all, the more expensive it is, the more difficult it will be for foreign investors to accept. That is to say, while enjoying the entry-level price, it is necessary for Tengfei group to purchase the supporting aircraft avionics system, otherwise it can't match the established inertial navigation system.

If you think this condition is unacceptable, it's not impossible. If you can find out about the $3.8 million laser gyroscope, you can take the same model of Boeing 737 if you can give it $4.6 million.

The Americans are like this, and the European side is not so good either. They just treat Tengfei group as a fat sheep, so that the asking price of the small laser gyroscope can catch up with the overseas sales quotation of tm-9 business aircraft.

The advantage of tm-9 is cost-effective. As a result, all the key components are broken. The future development of this group is very weak.

Therefore, in the end, Tengfei group can only make a difficult choice, and continue to use the domestic mechanical gyroscope as the core of the inertial navigation system, combined with radio navigation, to form the basic framework of tm-9 navigation system.

However, this set of navigation system was submitted to the aviation authorities in Europe and the United States, and it was unexpectedly called back, because the inertial navigation system with laser gyroscope as the core was widely used in the mainstream official business in Europe and the United States, and the navigation accuracy was higher, so as to improve the safety of the aircraft.

Tm-9, as a business aircraft, still uses the inertial navigation system with the old-fashioned mechanical gyroscope as its core. What should we do if something goes wrong? How can you embarrass the rich who buy this kind of plane?

At that time, Tengfei group couldn't say a word. In fact, you didn't have a laser gyroscope, and you didn't want to spend money on it. Under the condition that the mainstream aviation industry in Europe and the United States was widely used, you didn't use it. The aviation safety audit standards with super high requirements in Europe and the United States must be one card and one standard.

It's just like that the sixth national standard for automobiles has been issued, and some people's railways are still engaged in the fourth national standard. How can the vehicle management department let you go on the road?

The same is true of the aviation industry.

How else can we say that the developed countries face the developing countries? No matter how they change their postures, they are all playing with dimension reduction.

Sometimes you really don't have to do anything deliberately. If you take out a few key technologies similar to laser gyroscopes, you can even count the number of people who can reach the pass line.

And then Then the developed countries can happily cut leeks.

This is why Bombardier of Canada and Embraer of Brazil will transfer their well-developed regional airliner business to Airbus of Europe and Boeing of the United States at a low price more than 20 years later.

It's not that these two regional jet giants are not good enough, but that they do not have the whole aviation industry chain at all. Many key technologies depend on imports, and even core equipment like laser gyroscope can only be selected from the United States or Europe.

It's just like eating some soup left behind the giants. As the regional airliners of the two companies grow bigger and bigger, they will soon become trunk airliners and compete for the mainstream civil aviation airliner market. The United States and Europe immediately get stuck in key technologies.

No embargoes or sanctions, that is to say, the skill point of price is full, all kinds of lions open their mouths, push the cost of your products to a high level, and then You can cut a wave of leeks.

It is because of this that we are now able to make a difference in aviation and aerospace on this planet. It's not that we need to send a plane into space and send a satellite into space. We need to be able to use it, easy to use it, and people can't let it go.

Only in this way can capital and technology be mobilized to form a virtuous circle. If we only focus on investment and do not seek returns, that is the typical Soviet model, which will not last for a long time.

In order to form a virtuous circle in the global aviation and aerospace field, what Tengfei group needs to do at this stage is to make up for its own shortcomings.

Navigation system, as the most important infrastructure of aviation and aerospace, is a barrier that Tengfei group can't get around. People have laser gyroscopes, they have star navigation, and they have autonomous and controllable satellite navigation. No matter how beautiful your plane is and how excellent your flight performance is, there is a great chance that you will become blind or deaf in the sky, That's a plane nobody dares to buy.This is also the reason why Zhuang Jianye took out the Soviet Union's navigation technical data and tried his best to share the results, which can not only reduce the R & D cost of Tengfei group, but also obtain technical support at a very low cost after achieving the results, so as to improve its own products and improve the competitiveness of products.

From this point of view, Tengfei group is making more than 10 million yuan.

The implementation also confirmed Zhuang Jianye's expectation, because soon Tengfei group obtained the first batch of achievements from the navigation technology alliance, that is, zenith-1 star navigation system.

The system adopts a set of domestic star sensor, which is installed on the gyro platform imported from Russia with laser gyroscope as the core. The optical system is of two-piece casselolin structure. The main lens and secondary lens are made of beryllium, with silver plated surface and no poke structure, which are directly installed in the platform hole.

The detector uses Canon's 80 * 80 pixel CCD photo sensitive assembly and matching semiconductor cooler. The aperture of the star sensor optical system is 90mm, with a mechanical shutter. It is usually hidden in the middle of the ty-6 UAV's fuselage. When it is used, the light shield is pressed by a spring, ejected when it is used, and automatically aims at the anchored star constellation.

The satellite measurement accuracy of the whole system can reach 2.8 angle, and the single navigation accuracy can reach 95 meters. Combined with the inertial navigation system, the precision can be further improved to 60 meters.

You know, the highest accuracy of ty-6 UAV using the low configuration version of GPS is only 80 meters. From this point of view, zenith-1 star navigation system can completely replace the low configuration version of GPS.

After learning about tiandingxing-1 star navigation system, Chen Fang nodded his approval, but he said to Zhuang Jianye with his teeth: "things are good things, that is The price is a little high. "
