Chapter 1468

At that time, many people in the aerospace industry criticized China's stubbornness in taking off and insisted on copying the stubbornness in aviation in the aerospace field.

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

So we should be flexible or flexible.

If the precision of the miniaturized atomic clock is not enough, use the large one. First solve the problem, and then slowly solve the others.

Can Zhuang Jianye, who personally serves as the chairman and senior party official of China Tengfei Aerospace Technology Co., Ltd. (Group) and the founder of ZTM NB space exploration company, understand these things?

He knows better than anyone that the question is, what should the headquarters do about the urgent demand for anti-ship ballistic missiles?

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

However, due to the lack of reconnaissance and target indication equipment between the first island chain and the second island chain, the actual combat capability of the anti-ship ballistic missile is not outstanding.

This means that soldiers have guns and bullets in their hands, but the three-point and one-line aiming system is not done well. As a result, bullets can't even scare people.

You know, 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.

Such an expensive weapon system is not cost-effective if it is only an ordinary ship of thousands of tons. It can only be cost-effective if it is greeted by a big guy of more than 50000 tons.

Because of this, the headquarters is eager to put this weapon system into practice, so it can afford so many years of large investment.

As a part of the system, if the marine environment monitoring satellite wants to be practical, it must meet two conditions: the first is high resolution, fast transmission and fast refresh rate; The second and most critical point is to realize rapid replenishment through the rapid launch system in case of emergency.

This requires that the mass of the satellite should not exceed 700 kg, 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. If the fixed facilities and other accessories inside the fairing are removed, the payload can reach about 700 kg.

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

Another ztm-nb-6c solid launch vehicle fast launch system adopts the aviation launch system, that is, a modified H-6 bomber is used to fly to an altitude of 11000 kilometers with ztm-nb-6c solid launch vehicle, and then release the ztm-nb-6c Solid Launch Rocket to make it carry the satellite into the predetermined orbit.

Compared with the fixed launch system, the aviation launch system has less requirements for window period, site and weather conditions. In theory, as long as the airport is appropriate, it can be launched by carrier rocket at any time, which has high practical significance for rapid replenishment of satellites in emergencies.

However, due to the limitations of the body structure and load of H-6, the payload of ztm-nb-6c solid launch vehicle is not high, only about 600 kg.

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

Taken together, they account for 65% of the total mass of marine environment monitoring satellites. Overweight is inevitable.

Of course, if these two atomic clocks can ensure the accuracy and service life at the same time, Zhuang Jianye also recognizes that after all, their own ztm-nb-6 and ztm-nb-6c do not exist to launch large spacecraft. After all, in an emergency, they do not have the time to produce large spacecraft that consume time and energy. Small spacecraft with high efficiency is the king.

Everyday, it's good to be able to use it, and it doesn't matter if you can't use it.

But the problem is that the manufacturer told Zhuang Jianye that the service life of the two atomic clocks will last only two years, which makes Zhuang Jianye depressed. It can't last two years to send them up with so much effort. It's better to gamble according to their own ideas. Naturally, everyone is happy with their success. Can't they at least test the reliability of their own fast launch system.

So Zhuang Jianye used the original 580kg scheme and used rubidium atomic clock and hydrogen atomic clock with a combined weight of less than 100kg. As expected, they were completely scrapped in less than a year.

However, unlike other people's rumors that China's take-off may be unable to recover in the aerospace field, although China's take-off's aerospace business department failed on the marine environment monitoring satellite, it also obtained a series of valuable data, especially the operating characteristics and performance after failure of the two atomic clocks, combined with the disassembly and research of relevant products by China's take-off and research and development units, The root cause was soon found.

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

This is also a matter of no way. After all, the current domestic technical level is limited. Even profitable industries focus on the expansion of real estate and business, and the pursuit of technology is not prominent, let alone the driving force.

After joining the World Trade Organization for so many years and with the deepening of globalization, it is natural to optimize the allocation. If there is a lack of technology, just find a place to buy it. It is much more time-consuming and labor-consuming than your large investment. Not to mention, the efficiency is also much higher.

But the problem is that some things can be bought, and others don't sell you.

For example, at present, only manufacturers in the United States and Switzerland can produce processing equipment related to atomic clocks. People don't say they won't sell it to you, but they have repeatedly said that they have too many orders, and you can only wait three years.

You said you could pay more. I hope the workers can work an extra shift.

It's good not to say that. After saying that, the manufacturer can turn his face directly, and then tell you in a righteous way: their workers are not tools for making money, but free people. Overtime is impossible and will never be possible. All right, don't say anything. Our ideas are different. We won't sell you even if we have redundant equipment.

What do you mean being a bitch and erecting a memorial archway? That's it.

Lao Tzu didn't sell it not because of money, but because of his idea, what a tall reason.

But in fact, except for a few countries in Europe and America, these high-precision processing equipment and processes are not sold at all. After all, the essence of satellite accuracy is always in their hands. It is the king to monopolize outer space and grab excess profits.

Why should anyone else come and share the cake?

Of course, it would be too low to say these reasons so blatantly. After all, at this time, European and American countries need to face up, that is, go directly to the idea Dharma, not sell you, but we have different ideas and can't pee in the same pot. What should we do? I can only regret it!

Therefore, the research and development unit of the atomic clock is helpless. There is no technology at home and it is still stuck in the neck abroad. If it can be done, it will be a miracle. What else do you want?

After finding out the reason and understanding the situation, Zhuang Jianye was also a headache. Compared with other friends and businessmen in the aerospace field, he could also get relevant components and parts from abroad for assembly. China took off because the XXX act couldn't get even half a screw, the domestic research and development units pulled so close, and the task of the superior couldn't be delayed. What should we do?

There's no other way but to kill!
