Lin Yinghao's words attracted everyone's attention for a while.

Huang Mingshan also has some data on electromagnetic technology, which everyone calculates on the blackboard.

Zhang Hao looked at it and frowned a little.

In fact, the technology of Dayang Group has developed to the present, and it has a huge volume. Zhang Hao is now difficult to guide from the details.

Just say that at the moment, these formulas, data, etc., Zhang Hao can only barely look at a rough idea.

After all, there is still a difference between the mathematics and physics of this world and the world of the past. Different civilizations have formed different habits, symbols, etc. In particular, the mathematics of this world is inextricably linked to spiritual practice, gossip, elephant numbers, and so on.

The technology that has developed from this kind of mathematics is very different from the world that once was.

It can only be said that Zhang Hao gave a certain guidance and beginning, and there was not much interference from Zhang Hao in the later development. Especially now that he has absorbed the relevant knowledge in the advanced civilization textbooks, it is difficult for Zhang Hao to control the scientific system of the Dayang Group.

The only thing Zhang Hao can do is to point in a general direction. For example, space exploration, rocket technology, electromagnetic guide rail technology, etc. But more specifically, Zhang Hao can't intervene anymore.

Everyone calculates and discusses. Then he also contacted Ge Dong by phone to obtain relevant data.

Scientific research data cannot be exchanged casually. But it also depends on whom. Huang Mingshan, Ge Dong, Lin Yinghao, Leng Fengxue and others basically do not have such problems.

About an hour later, Lin Yinghao completed the preliminary and detailed calculations.

"Mr. Zhang, after preliminary calculations, the ejection of the electromagnetic guide rail is feasible. In this way, we can also compress the volume and weight of the rocket to less than 10 tons. But in this way, the rocket's own fuel can only provide an additional speed of 5 kilometers per second.

But for a rocket to gain enough speed to go into space, the electromagnetic guide needs to provide up to a total of energy equivalent to an initial velocity of 20.35 kilometers per second. ”

"No, the orbiting speed is 25.3 kilometers per second, the planet's rotation surface speed is 1.68 kilometers per second, and the rocket provides a second speed of 5 kilometers. The rail only needs to provide a speed of 18.62 kilometers per second. ”

"But if we send a rocket to an altitude of 1,500 kilometers, it will consume part of the potential energy. According to the calculation of free fall, according to the calculation of the gravitational force of the planet, the speed of free fall can reach 1.73 kilometers per second. ”

Zhang Hao rubbed his brows, "Okay." How difficult is it for the rail gun to provide a speed of 20.35 kilometers per second?"

"It's a bit big. But compared with the previous way of simply launching rockets, there is always hope for a breakthrough.

To lift a 10-ton rocket to 10.35 kilometers per second, it takes about 300 million units of electricity. This is not counting the losses of the conversion process, etc.

We have the best thermal power generation set now, the power per hour is 800,000 units of electricity, is per hour. That's 222 units of electricity per second.

According to the preliminary calculation of our current electromagnetic technology, considering the bearing capacity of the rocket, the maximum acceleration of the rocket can reach 280 meters per square second.

To reach a speed of 20.35 km/s, take a whole number, and take 73 seconds.

300 million units of electricity are output in 73 seconds, and an average of 4.11 million units per second is required. According to the data calculation of one unit 222, 18,500 generator sets are needed.

According to the calculation that a generator set covers an area of 18×35 square meters, it needs 11.65 square kilometers of land to put down.

The above figures are all theoretical values. The actual power conversion rate is about 80%, and the generator sets are not likely to be stacked together like building blocks.

In reality, we need to build a 30-square-kilometer mega-plant, which requires at least 23,100 units, all of which are at their peak and are carrying out all orders without error.

In the end, it will be possible to send a rocket into space.

During this period, even a small fluctuation in numbers can wipe out all efforts. ”

When Zhang Hao heard these numbers, his mouth opened.

I thought about the difficulty of launching a rocket, but I didn't expect it to be so difficult. It's simply an impossible task!

The total number of units of all the thermal power plants of the Dayang Group is only about 3,000. This has supported almost all of the industrial needs of Dayang Group.

However, Lin Yinghao didn't finish speaking, "Mr. Zhang, what I just said is about energy. There is also the more important issue of the launch rail.

About 746 km is required for the launch rail. 746 kilometers of guide rails, without the slightest flaw, must be flawless. There can be no dust, no air, and no bumps in this process.

In addition, stationary rockets require vehicles, which also need to accelerate synchronously. Actual situation...... Maybe it's a lot more complicated. ”

"Didn't you just say that the rail only needs 12 kilometers?"

"Well, it's calculated according to the weapon level. But rockets are more vulnerable, and they need to be considered for their endurance. In addition, for every half of the rails, a fourfold increase in the number of electric units is required. Shortening the rails is never a good idea. ”

Zhang Hao closed his eyes, thought for a moment and suddenly said: "When the guide rail first started to accelerate, there was no need to use electromagnetic technology at all. Acceleration can be done with steam catapults or explosives. You can even use an external engine, etc.

Wait until the speed reaches the chemical limit before using the electromagnetic guide to accelerate.

Is 10 tons of rockets too big? We can study whether the weight can be further reduced.

By the way, aren't we studying the use of nuclear energy right now? Maybe we can try to study the technology of nuclear power plants, etc.

As for the problem of the accuracy of the guide rail, let's study it slowly in the future.

Now I finally have a direction. ”

After that, Zhang Hao hurriedly ended the conversation. There was no way, he was also shocked by these numbers.

What is astronomical, and what is even more terrifying than astronomical numbers is 'exploring astronomical numbers'!

23,100 generating units is still the latest thermal power generation technology of the Dayang Group, do you know how much it will cost? Zhang Hao still remembers that a thermal power plant project was approved a few years ago, with 12 units of 800,000 yuan and a total budget of 300 million high-grade spirit stones. And that's not even counting the power grid and so on.

If you really want to connect 23,100 generator sets in parallel, the cost of power grid engineering alone is absolutely astronomical.

So this terrifying figure directly made Zhang Hao make a judgment: launch a rocket purely with electromagnetic guide technology, just think about it, don't take it seriously!

It's scary.

In addition, 746 kilometers of guide rails, which were previously made of weapon-grade guide rails, had a scrap rate of up to 80 percent, and the accuracy was required to reach 10 microns, that is, 0.01 millimeters.

If 746 kilometers of rails were to be built according to this requirement, the Dayang Group would go bankrupt. And in reality, space launch requirements will only be higher!

However, the difficulties are only temporary, and now there is finally a direction.

The previous research was not useless, but accumulated a wealth of scientific science and knowledge, especially the gravitational force, air resistance, potential energy, planetary rotation, orbit, atmosphere, formation, etc., with a full understanding.

Especially in terms of formation and storage space technology, no one expected that when the speed reached 16.8 times the speed of sound, that is, 8.4 kilometers per second, there would be an unstable situation.

But it's understandable when you think about it. When the speed reaches a certain level, the relationship between matter and space will become closer and closer, and problems will inevitably occur.

Of course, the scientists of the Ocean Group believe that there must be a solution for advanced civilizations, but they have not found it yet.

On the one hand, Zhang Hao could only let people find answers from advanced civilizations, including the ruins of the Liuli Island spaceship that were still being explored, and on the other hand, he suspended the research on space formations and other things - it was too different from the actual requirements, and continuing to study would only be a waste of financial resources in a short period of time.

In addition, it is necessary to increase research in physical technology. At present, it seems that physical technology is the most reliable.

In other words, the technology in the formation is not impossible, after all, it is naturally not simple to support a cultivation civilization. However, the Ocean Group does not have enough ability to completely crack the formation problem for the time being. After all, this is something left over from a high-level civilization.

The Ocean Group began new research, but the research and launch of rockets continued. On the one hand, it is to study technology, and on the other hand, it is also to beat the rabbit with grass - by the way, draw a pie for the allies of the Ocean Group.

The current international situation, although the overall situation is still within the expectations of Dayang Group and Zhang Hao, has gradually gotten out of control.

In a word: the master of the law level is too brutal!

Although the attack of a nuclear bomb is terrifying, such as the "two fat men" of the Ocean Group, the nuclear bomb is nothing more than a one-time one. On the contrary, masters of the Faxiang level can continue to destroy - the theoretical lifespan of these masters is as high as two thousand years.

Although the nuclear deterrence of the Ocean Group is still effective, with this duel of masters at the level of the French minister, the influence of nuclear deterrence has dropped to the freezing point.

This is, after all, the world of cultivation!

Therefore, the Ocean Group should explore outer space as soon as possible, hoping to get a breakthrough opportunity from outer space. According to the vague description of the exercises, the masters of the Dayang Group generally believe that going to outer space may help break through to a higher level.

Practicing "Zhou Tiangong", what's the matter with lying on the ground!

This statement is very reasonable, and Zhang Hao is also moved. It's just that this planet is a bit big, and it's not easy to break through.

However, Mr. Zhang has a lot of things, and he will arrange the aerospace mission to inspect the next stage of the Dayang Group: the standardization of practice.

Now the Dayang Group is about to establish a national education and cultivation system in the Xihai Principality, and the 'standard textbook' compiled by the Dayang Group's legal masters has entered the review stage.

It is foreseeable that in the new semester after June, schools across the country will be able to use the new teaching materials. However, the cultivation materials need to be equipped with pills. At present, the ocean medicine field of Dayang Group has begun to be picked, and Xinglintang has begun to test the new pill production line.

Dayang Group is still under great pressure to meet the supply of pills from some schools across the country and possibly even in the country of Qixia at the same time.

However, before these things were done, something happened to Liuli Island and the spaceship ruins.
