And this is only the mainline airliner market, the demand for larger regional airliners and business jets is even greater.

Not to mention others, the main reason why the TM-9 series of small business jets developed and produced by Tengfei Group has been unable to open the international market is because the airworthiness certificate of Europe and the United States has never been applied.

The most difficult factors are naturally the majority, but their own shortcomings are also the main reason for not being able to break the shackles, take the navigation system as an example, business jets pay more attention to safety and privacy than ordinary civil airliners.

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

Tengfei Group did not consider importing the most advanced laser gyroscope as the core of the inertial navigation system at that time, but the problem was that the foreign asking price was too expensive, and the entry-level price was 1.8 million US dollars.

This price is converted into RMB, which is enough to buy a top-of-the-line version of the TM-9 business jet.

If this is the only thing, a little more expensive is a little more expensive, but then the conditions of foreign investors Tengfei Group are difficult to accept, that is, to enjoy the entry-level price at the same time, Tengfei Group needs to purchase supporting aircraft avionics systems, otherwise it will not be able to match the formulated inertial navigation system.

If you feel that this condition is unacceptable, it is not impossible, the $3.8 million laser gyroscope understands, if you can come up with $4.6 million, the Boeing 737 can be taken directly.

The Americans are like this, and the European side is not much better, completely slaughtering the Tengfei Group as a fat sheep, so that the asking price of the small laser gyroscope has caught up with the overseas sales quotation of the TM-9 business jet.

Where can this Tengfei Group stand it, the advantage of TM-9 is cost-effective, but as a result, all the key components are broken, and the future development of this Tengfei Group is very weak.

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

However, this navigation system submitted to the aviation authorities in Europe and the United States was unexpectedly beaten back, because the mainstream of Europe and the United States generally uses the laser gyroscope as the core of the inertial navigation system, the navigation accuracy is higher, so as to improve the safety of the aircraft.

As a business jet, the TM-9 even uses the old-fashioned mechanical gyroscope as the core of inertial navigation, what if it fails? How can you make the rich people who buy this kind of aircraft embarrassed?

At that time, Tengfei Group was scolded and couldn't say a word, the fact is that you don't have a laser gyroscope, and you are not willing to spend money to buy, under the conditions of the mainstream aviation industry in Europe and the United States, you are useless, and the ultra-high aviation safety audit standards in Europe and the United States must be a card and a standard.

It's like the National VI standard for cars has been introduced, and some people are still engaged in the National IV standard cars, how can the vehicle management department let you go on the road?

The same is true for the aviation industry.

Otherwise, no matter how developed countries change their posture in the face of developing countries, what people are playing is dimensionality reduction.

Sometimes you really don't need to deliberately do anything about it, take out a few key technologies similar to laser gyroscopes and put them there, and the entire earth can reach the passing line and even count a slap.

And then...... Then the developed countries on this slap can happily cut leeks.

That's why, more than two decades later, Canada's Bombardier and Embraer are selling their well-developed regional airliner business to Airbus in Europe and Boeing in the United States.

It's not that these two regional airliner giants are not good enough, but that the two companies don't have the whole aviation industry chain at all, and many key technologies rely on imports, and even core equipment such as laser gyroscopes can only choose between the United States and Europe.

Seeing that the regional airliners of the two companies are getting bigger and bigger, they are about to become trunk airliners to compete for the mainstream civil airliner market, and the United States and Europe are immediately stuck in key technologies.

It is also forbidden to ban luck and sanctions, that is, to fill the price of this skill point, all kinds of lions open their mouths, and push the cost of your product to unattainable as soon as they come and go, and then ...... You can cut a wave of leeks beautifully.

Because of this, the current appearance of aviation and aerospace on this planet is not to send planes into the sky and send satellites into space to finish, but also to be able to use, easy to use, and people can't put it down if they use it.

In this way, capital and technology can be mobilized to form a virtuous circle, and if you only invest and do not ask for returns, it is a typical Soviet model, which will not last long.

If Tengfei Group wants to form a virtuous circle in the global aviation and aerospace field, what it 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 hurdle that Tengfei Group can not bypass, people have laser gyroscopes you don't have, people have starlight navigation you don't have, people have independent and controllable satellite navigation you don't have, even if your plane is beautiful, no matter how good the flight performance is, there is a high probability of becoming blind and deaf in the sky, and no one dares to buy an airplane.

This is also the reason why Zhuang Jianye took out the Soviet navigation technology data obtained and tried his best to share the results, which can not only reduce the research and development costs of Tengfei Group, but also obtain technical support at a very low cost after the results are obtained, so as to improve their own products and improve the competitiveness of their products.

From this point of view, Tengfei Group not only earns 10 million, but also more than 10 million.

The implementation also confirmed Zhuang Jianye's expectations, because soon Tengfei Group obtained the first results from the navigation technology alliance, that is, the Zenith-1 starlight navigation system.

The system adopts a set of star sensors independently developed in China, which is placed on a gyroscope platform imported from Russia with laser gyroscope as the core, the optical system is a two-piece Cacelorin structure, the main lens and the secondary lens use beryllium as the material, the surface is silver-plated, and the non-poke structure is directly installed in the platform hole.

The detector adopts a Japanese Canon 80*80 pixel CCD photoreceptor and a matching semiconductor cooler, the aperture of the star sensor optical system is 90mm, with a mechanical shutter, which is usually hidden in the middle of the fuselage of the TY-6 drone, and the lens shield is spring compressed when used, which pops out when in use, and automatically aligns with the anchored star constellation.

The star measurement accuracy of the whole system can reach up to 2.8 angles, and the accuracy of individual navigation can reach 95 meters, and the accuracy can be further improved to 60 meters with the implementation of composite navigation with the inertial navigation system.

You know, the TY-6 UAV uses the highest accuracy of the civilian low-profile version of GPS is only 80 meters, from this point of view, the Zenith Star-1 starlight navigation system can completely replace the low-profile version of GPS.

After Chen Fang learned about the Zenith-1 starlight navigation system, although he expressed his approval, he still said to Zhuang Jianye with his teeth: "Things are good things, they are ...... The price is a bit more expensive. ”
