Chapter 801 It¡¯s just...the price is a bit expensive

Previous page        Return to Catalog        Next page

    And this is only the mainline passenger aircraft market. The demand for larger regional passenger aircraft and business aircraft is even greater.

    Not to mention other things, the main reason why the TM-9 series of small business jets developed and produced by Ascendas Group has been unable to enter the international market is because it has never been able to apply for airworthiness certificates in Europe and the United States.

    The most difficult factors are naturally the majority, but their own shortcomings are also the main reason why they cannot break the shackles. Take the navigation system as an example. Business jets pay more attention to safety and privacy than ordinary civil aviation aircraft.

    However, when Ascendas Group developed the TM-9, the only thing available in China was the old-fashioned inertial navigation system with a mechanical gyroscope as the core.

    At that time, Ascendas Group had not considered importing the most advanced inertial navigation system with laser gyroscope as the core. The problem was that the asking price abroad was too expensive, with the entry-level model costing US$1.8 million.

    This price converted into RMB is enough to buy a matching version of the TM-9 business jet.

    If that's all, it's more expensive, but then the conditions of foreign investors are difficult for Ascendas Group to accept. That is, while enjoying the entry-level price, Ascendas Group needs to purchase supporting aircraft avionics systems, otherwise it will not be matched.  developed inertial navigation system.

    If you think this condition is unacceptable, it¡¯s not impossible. Let¡¯s take a look at the $3.8 million laser gyroscope. If you can come up with $4.6 million, you can take away the same model as the Boeing 737.

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

    How can Ascendas Group endure this? Originally, the advantage of TM-9 was its cost-effectiveness, but as a result, it was completely destroyed for one key component. Ascendas Group's future development will be very weak.

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

    However, when this navigation system was submitted to European and American aviation authorities, it was rejected as expected, because inertial navigation systems with laser gyroscopes as the core are commonly used in mainstream European and American official business, and the navigation accuracy is higher, thereby improving the aircraft's side.  security.

    As a business jet, the TM-9 still uses the old-fashioned mechanical gyroscope as its core inertial navigation. What if something goes wrong?  How can you embarrass the wealthy people who buy this kind of aircraft?

    At that time, Ascendas Group was criticized for not being able to utter a single word. This is the fact. If you don¡¯t have a laser gyroscope, and you are not willing to spend money to buy it, you are useless under the conditions that are commonly used in the mainstream aviation industry in Europe and the United States. Europe and the United States have extremely high requirements.  The aviation safety audit standard must be one card and one accurate.

    This is just like the National VI standard for cars has been introduced, and some Rentou Iron and Steel Co., Ltd. are still producing cars with National IV standards. How can the vehicle management department let you go on the road?

    The same is true for the aviation industry.

    ??How about other words, no matter how the developed countries change their positions when facing developing countries, what they are doing is dimensionality reduction.

    Sometimes you really don¡¯t have to do anything deliberately, just take out a few key technologies like laser gyroscopes and put them somewhere, and you can count the number of people on the entire planet who can reach the passing line.

    ¡°Then¡­then the developed countries in this slap can happily cut leeks.

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

    It¡¯s not that these two regional airliner giants are not good enough, but that the two companies do not have the entire aviation industry chain at all. Many key technologies rely on imports, and even core equipment such as laser gyroscopes can only be purchased from the United States or Europe.

    I usually just follow the giants and eat some leftover soup. I am watching the regional airliners of the two companies getting bigger and bigger. They will soon become mainline airliners and compete for the mainstream civil aviation passenger aircraft market. The United States and Europe will soon develop key technologies.  Get stuck in the neck.

    There are no embargoes or sanctions, just max out the price skill point, all kinds of lions will open their mouths, and push the cost of your products to unattainable heights, and thenyou can harvest a wave of leeks beautifully.

    Because of this, the aviation and aerospace industry on this planet are now trying to make a difference. It is not just about sending planes into the sky or launching satellites into space, but it also needs to be usable, easy to use, and put away after people use it.  No less.

    ¡° Only in this way can funds and technology be mobilized to form a virtuous cycle. If we just invest without asking for returns, it is a typical Soviet model and will not last long.

    And Ascendas Group wants to form a virtuous cycle in the global aviation and aerospace fields.Huan, all he has to do at this stage is make up for his shortcomings.

    Navigation system, as the most important infrastructure of aviation and aerospace, is a hurdle that Ascendas Group cannot get around. Others have laser gyroscopes but you don¡¯t have them. Others have starlight navigation but you don¡¯t have them. Others have autonomous and controllable satellite navigation but you don¡¯t have it.  No matter how beautiful your aircraft is and how excellent its flight performance is, there is a high chance that you will become blind or deaf when it is in the sky, and no one would dare to buy that aircraft.

    This is also the reason why Zhuang Jianye took out the Soviet navigation technical data he obtained and tried his best to share the results. Not only can it reduce the research and development costs of Ascendas Group, but after the results are obtained, Ascendas Group can also obtain technical support at a very low cost, thereby improving  own products to improve product competitiveness.

    Calculated from this aspect, Ascendas Group earns not just 10 million, but even hundreds or even 10 million.

    The implementation also confirmed Zhuang Jianye¡¯s expectations, because soon Ascendas Group obtained the first batch of results from the navigation technology alliance, which was the Zenith-1 starlight navigation system.

    The system uses a domestically developed star sensor, which is placed on a gyro platform imported from Russia with a laser gyroscope as the core. The optical system is a two-piece Casserolin structure, and the primary lens and secondary lens use  Beryllium is used as the material, the surface is silver-plated, there is no poking structure, and it is directly installed in the platform hole.

    The detector uses Japanese Canon 80*80 pixel CCD photosensitive components and matching semiconductor refrigerators. The aperture of the star sensor optical system is 90mm, with a mechanical shutter. It is usually hidden in the middle of the fuselage of the ty-6 drone.  The lens hood is spring-pressed, pops up when in use, and automatically aligns with the anchored star constellation.

    The star measurement accuracy of the entire system can reach up to 2.8 degrees, and the single navigation accuracy can reach 95 meters. When combined with the inertial navigation system to implement composite navigation, the accuracy can be further improved to 60 meters.

    You should know that the highest accuracy of the civilian low-end version of the ty-6 drone using GPS is only 80 meters. From this perspective, the Zenith-1 starlight navigation system can completely replace the low-end version of GPS.

    After Chen Fang learned about the Zenith-1 starlight navigation system, although he nodded in approval, he still chewed his teeth and said to Zhuang Jianye: "The stuff is good, but the price is a bit expensive."
