Chapter 1468: Breaking a bloody path

Previous page        Return to Catalog        Next page

    At that time, many people in the aerospace industry criticized China Tengfei for being too stubborn and insisting on copying the stubbornness in aviation in the aerospace field.

    If the aerospace industry has been so stubborn in the past few decades, how could we develop two bombs and one satellite in that era of economic downturn and backward technology?

    So you have to adapt when you need to.

    The miniaturized atomic clock is not accurate enough, so just use a larger one. Solve any problems first, and we will solve the other problems later.

    ???Can Zhuang Jianye, who personally serves as the chairman of China Tengfei Aerospace Technology Co., Ltd. (Group) Company and a senior party official and the founder of ztm-nb Space Exploration Company, understand these things?

    He understands better than anyone else that the question is, what should the headquarters do about its urgent need for anti-ship ballistic missiles?

    You must know that the anti-ship ballistic missile based on a certain medium-range launch vehicle equipped with a hypersonic gliding warhead has completed several rounds of testing, and the overall performance is very powerful.

    But because of the lack of reconnaissance and target designation equipment between the first island chain and the second island chain, the actual combat capabilities of anti-ship ballistic missiles are not outstanding.

    This is equivalent to the fact that the soldier has a gun and bullets in his hand, but the three-point and one-line aiming system is not done well. As a result, the bullet only makes a sound when fired, and cannot even scare people.

    You must know that the headquarters has invested nearly 30 billion yuan, and the unit price of an anti-ship ballistic missile equipped with a hypersonic gliding warhead is as high as 820 million yuan.

    "It is not cost-effective to use such an expensive weapon system to attack ordinary ships of several thousand tons. It can only be cost-effective to attack large ships of more than 50,000 tons."

    Because of this, the headquarters is eager to put this weapon system into actual combat, so that it can be worthy of the large investment over the years.

    As part of the system, marine environment monitoring satellites must meet two conditions if they want to be put into practice. The first is high resolution, fast transmission, and rapid refresh rate; second, and most crucial point, is that in emergencies  Rapid replenishment can be achieved through the rapid launch system.

    This requires that the mass of the satellite cannot exceed 700 kilograms, because the maximum load of the low-Earth orbit of the ztm-nb-6 solid launch vehicle rapid launch system developed by China Tengfei is 1.5 tons, excluding the fixed facilities and other components inside the fairing  With accessories, the payload can reach about 700 kilograms.

    This is a payload that can reach 700 kilograms under fixed land-based launch.

    Another ztm-nb-6c solid launch vehicle rapid launch system uses an aviation launch system, that is, using a modified H-6 bomber, equipped with a ztm-nb-6c solid launch vehicle, it can fly to 11,000  Kilometers of altitude, and then release the ZTM-NB-6C solid launch vehicle to carry the satellite into the predetermined orbit.

    Compared with the fixed launch system, the aviation launch system has smaller requirements on window period, site and weather conditions. In theory, as long as the airport is suitable, the launch vehicle can be launched at any time, which is very convenient for quickly replenishing satellites in emergencies.  practical significance.

    However, due to the H-6¡¯s body structure and its own load limitations, the payload of the ZTM-NB-6C solid launch vehicle is not high, only about 600 kilograms.

    Based on this, the total mass of the marine environment monitoring satellite developed by China Tengfei was controlled at 580 kilograms. However, the mass of domestic high-precision rubidium atomic clocks at that time exceeded 150 kilograms, and the backup hydrogen atomic clock reached 230 kilograms.

    The two together account for 65% of the total mass of the marine environment monitoring satellite, so overweight is inevitable.

    Of course, if these two atomic clocks can not only ensure accuracy but also ensure service life, Zhuang Jianye will agree. After all, their own ztm-nb-6 and ztm-nb-6c are not designed to launch large spacecrafts. After all,  In an emergency, there is no time to produce large spacecrafts that are time-consuming and labor-intensive. Small spacecrafts with high efficiency are the way to go.

    In daily life, it¡¯s good if you can use it, and it doesn¡¯t matter if you can¡¯t.

    But the problem is that the manufacturer told Zhuang Jianye that the service life of the two atomic clocks was only two years. This made Zhuang Jianye depressed. Even after putting so much effort into sending them, they would not last two years. It was better to take a gamble according to his own ideas and succeed.  Of course everyone is happy, at least they can test the reliability of their own rapid launch system.

    So Zhuang Jianye used the original 580-kilogram plan, using a rubidium atomic clock and a hydrogen atomic clock that together weighed less than 100 kilograms. As expected, they were completely scrapped in less than a year.

    It's just different from other people's rumors that China Ascendas may fail in the aerospace field as a result. Although China Ascendas's aerospace business department failed in the marine environment monitoring satellite, it also obtained a series of valuable data, especially the operation of the two atomic clocks.  Characteristics and performance after failure, combined with the disassembly and research of related products by China Tengfei and its research and development units,The root cause was quickly found.

    In a word, the manufacturing process is too backward, resulting in insufficient processing accuracy, resulting in the two atomic clocks being unable to meet the design requirements.

    There is nothing we can do about this. After all, the current domestic technical level is limited. Even in profitable industries, they focus on real estate and business expansion. The pursuit of technology is not outstanding, let alone the motivation.

    We have been members of the World Trade Organization for so many years. As globalization deepens, it is natural to optimize the allocation. If there is a lack of technology, just buy it from somewhere that can make it. It is much better than investing a lot of time and energy on your own.  , the efficiency is also much higher.

    But the problem is that there are some things that you can buy, and there are some things that people won¡¯t sell to you at all.

    ¡° For example, for atomic clock-related processing equipment, currently only manufacturers in the United States and Switzerland can produce it. They don¡¯t say they won¡¯t sell it to you. They just repeatedly say that they have too many orders and you can only wait three years if you want it.

    You said you can add money and hope the workers can work overtime.

    It's okay if you don't say this, but if you say it, the manufacturer will immediately turn against you, and then tell you righteously: their workers are not tools to make money, but free people. It is impossible to work overtime, and it will never be possible.  , Okay, don¡¯t say anything. We have different ideas. Even if we have extra equipment, we won¡¯t sell it to you.

    "What does it mean to be a bitch and still have to erect a memorial arch?"  That's it.

    "I don't sell it because of money, but because of ideas. What a lofty reason."

    But in fact, except for a few countries in Europe and the United States, they do not sell this kind of high-precision processing equipment and technology to outsiders at all. After all, this kind of fundamental issue related to satellite accuracy should always be in their hands. Such a monopoly outside the country  In this space, grabbing excess profits is the way to go.

    Why should others come over to share the cake?

    Of course, it would be a bit too low to say these reasons so blatantly. After all, European and American countries at this time still want to have some dignity, that is, they just go directly to the Dafa of ideas. It¡¯s not that we don¡¯t sell you, but that we have different ideas, so we can¡¯t even pee one another.  What should I do if I put it in the pot?  I can only regret it!

    Therefore, the research and development unit of the atomic clock is helpless. There is no technology in China, and the neck is still stuck abroad. If it can be made, it will be a miracle. What kind of bicycle is needed?

    After finding out the reason and understanding the situation, Zhuang Jianye also had a headache. Compared with other companies in the aerospace field, they can still get related components from abroad to assemble. China Takeoff couldn't even get half a screw because of the xxx bill.  , the domestic research and development units are so pushy, and the superiors¡¯ tasks cannot be delayed, what should we do?

    There is no other way but to carve out a bloody path!
