Chapter 1474 We have our hands full

Previous page        Return to Catalog        Next page

    Although you are a little uncomfortable with Zhuang Jianye¡¯s ubiquitous pretense, you have to admit that China has taken off in its dominance of deep ultraviolet nonlinear optical crystals.

    Why the purely domestic 193nm lithography machine broke through the technical bottleneck so quickly and became widely used is because the Ascendas Optics Research Institute, a subsidiary of China Ascendas, has made breakthrough progress in deep ultraviolet nonlinear optical crystals, which not only broke the foreign monopoly  , and also reduces power consumption by 40%.

    Because of this, when Zhuang Jianye said that the excitation light source in the atomic clock uses a laser with a deep ultraviolet nonlinear optical crystal as the core, everyone present was immediately enlightened.

    There is no way, China Takeoff is the ancestor of this field, of course it depends on how you play.

    "It's just a matter of a moment to admit the technical status. It's another thing to deal with Zhuang Jianye's sense of always talking about money and pretending to be 13.

    But Zhuang Jianye, just like all the big guys, whose old face is really covered by the hat of the dustproof suit, and no expression can be seen, is still talking non-stop: "There is no way, our ztm-nb-6 solid  The payload of the launch vehicle is only 700 kilograms, so the total weight of our new generation of marine environment exploration satellites is planned to be controlled at about 500 kilograms. Unfortunately, we did not achieve the expected results on the hydrogen atomic clock, so the subsequent marine environment exploration satellites had to  readjust¡­¡­"

    Zhuang Jianye sighed and looked quite helpless: "For this reason, we can only increase the total structural weight of the satellite platform from the original 519 kilograms to 637 kilograms. The dimensions are 2.8 meters long, 1.5 meters wide, and 1.2 meters high.  meters; the total power is 1.5 kilowatts, of which the communication load weighs 115 kilograms and the power is 808 watts. It uses precise positioning modules including rubidium atomic clocks and hydrogen atomic clocks, and cooperates with the current 1.5-meter global beam antenna and synthetic aperture radar to provide real-time information in key sea areas.  environmental conditions.

    Because of this, we plan to deploy the new generation of marine environment exploration satellites in a constellation, using three intersecting circular orbits with an average altitude of 238 kilometers. Each orbit will deploy three working satellites and one backup satellite, for a total of 12 satellites.  , the satellite operation period is 14 hours and 4 minutes.

    With the eight-year service life of the satellite, real-time updates of East Asian waters, especially the key sea areas between the first island chain and the second island chain, can be achieved in the first decade of the 21st century. This is still what we are doing.  The first phase of the marine environment exploration satellite project construction plan, the second phase will further double the number of constellations to 24, thereby achieving real-time refresh frequency in key sea areas in less than half an hour"

    Zhuang Jianye described the prospect of future marine environment exploration satellites as grand and exciting. That is to say, the venue is not right now and the clothes on his body are also a bit restrictive. If this were a large theme venue, there would be a large screen behind him and a packed audience in front of him.  , Zhuang Jianye put on a T-shirt and jeans, and promised to raise his hands and shout: "Let us suffocate for our dreams!"

    It's a pity that the big guys in front of him are all down-to-earth and practical people. Zhuang Jianye just screamed out flowers for his dreams, but the big guys were still unmoved, so Zhuang Jianye got a little more passionate and turned to reality and continued to sigh.  Said: "The main resistance that affects the advancement of our marine environment exploration satellite is funding. We originally expected the total cost of satellite manufacturing, launch and operation of the launch vehicle to be 2.8 billion yuan, but because our satellite is one month heavier than originally planned,  More than 100 kilograms, which results in an increase of more than 30 million yuan in each launch cost, and an overall overrun of nearly 400 million yuan"

    "Wait a minuteMr. Zhuang, what is the total cost of your 12 marine environment exploration satellites? 2.8 billion yuan?" Before Zhuang Jianye finished speaking, an accompanying aerospace expert frowned and asked.

    Hearing this, Zhuang Jianye quickly corrected himself: "2.8 billion was the previous budget. Isn't the satellite overweight now? The cost has been overrun. Now it has been raised to 3.2 billion."

    "Even 3.2 billion is wrong. The launch cost of 12 satellites is almost 1.2 billion yuan. The subsequent measurement and control, on-orbit maintenance and data transmission of the satellites will also cost 800 to 1 billion yuan. Yours  How much does a marine environment exploration satellite cost? Less than 100 million yuan per satellite?"

    "To be precise, it's 75 million yuan per pill." Zhuang Jianye corrected again: "But that's not the point. The key is the launch cost"

    "How much did you just say? 75 million yuan a piece? A satellite that uses rubidium atomic clocks, hydrogen atomic clocks, synthetic aperture radar and advanced communication equipment only costs 75 million yuan?"

    This time Zhuang Jianye was halfway through his words when he was interrupted again by the aerospace expert. Upon hearing this, Zhuang Jianye showed a look of shame that only young people often see on his face: "I feel ashamed to say that we didn't do a good job in cost control.  According to our original intention, we should have reduced the cost of the satellite to less than 50 million yuan. As a result the satellite was overweight alas It was all our fault that we did not do a good job in system integration.The country is in trouble"

    "If you are causing trouble to the country, then we old guys should go back to the mother's womb and rebuild it! A satellite of more than 600 kilograms only costs 75 million yuan. How can you cause trouble to the country? It is clearly just another matter.  Contribute to the country!"

    The aerospace expert finally couldn't help it anymore and simply didn't let Zhuang Jianye continue talking. If he had seen Zhuang Jianye pretending to be 13 before, at this moment, in the eyes of this expert, Zhuang Jianye was the best kid in the world.

    More than 600 kilograms, the unit price is only 75 million yuan, which can be found anywhere in the world. There is no way this is not an ordinary bargain, but as cheap as grandma¡¯s house.

    You must know that aerospace products are also gold-eating beasts. There is no way. Usually satellites and spacecraft are customized products. Not only are the material costs expensive, but the production cycle is also long. It usually takes less than half a year to assemble a 100-kilogram satellite.  Because of this, the cost of aerospace products is not generally expensive.

    Take a 600-kilogram satellite as an example. The usual cost price is around 150 million. This is still the basic price. If you add some advanced equipment, it can directly rise to 200 million.

    ??However, China Tengfei¡¯s satellite of the same level only costs 75 million, which is only half of the original price.

    This is like selling a Porsche 911 at half price. In the eyes of those who really know the goods, it is a huge bargain.

    Obviously, the aerospace expert is someone who knows the goods. Many of them were immediately ready to hand over the satellites designed by the aerospace institute he led to China Tengfei for production. But he stopped talking. After all, as an industry insider, he knew very well that satellites are  The cycle of growing things is so long. Usually a large factory cannot produce 10 plants in a year even if it works overtime.

    China Ascendas has a lot of aerospace missions, and he may be too busy to handle them. How can he have the spare time to undertake other businesses? So he can only shake his head regretfully: "Unfortunately, we have several satellite projects on hand. If you China Ascendas  It would be nice to be busy"

    "Professor, if we need China to take off, just give us your orders. Our newly established satellite production plant has an annual production capacity of 128 satellites. If you have any work, just leave it to us. We will be busy"

    "What did you say?" The expert was shocked when he said this: "The annual output is one hundred twenty-eight pills?"
