Lin Yinghao's words immediately attracted everyone's attention.
Huang Mingshan also has some data on electromagnetic technology, and everyone is doing calculations on the blackboard.
Zhang Hao looked at it and frowned a little.
In fact, Dayang Group's technology has developed to a huge scale now. It is now difficult for Zhang Hao to provide guidance in details.
As far as these formulas, data, etc. are concerned, Zhang Hao can only barely take a look at them.
After all, the mathematics, physics, etc. of this world are different from the world of the past. Different civilizations have formed different habits, symbols, etc. In particular, the mathematics of this world itself is closely related to spiritual practice, Bagua, Xiangshu, etc.
wisps of contact.
The technology developed from such mathematics is very different from the world of the past.
It can only be said that Zhang Hao gave some guidance and a beginning, and Zhang Hao did not interfere much in the subsequent development. Especially now that he has absorbed relevant knowledge from advanced civilization textbooks, it is now difficult for Zhang Hao to control the scientific system of Dayang Group.
The only thing Zhang Hao can do is to point in a general direction. For example, exploring space, rocket technology, electromagnetic rail technology, etc. But Zhang Hao can no longer get involved in the more specific ones.
Everyone calculated and discussed at the same time. Then they contacted Ge Dong by phone to obtain relevant data.
Scientific research data cannot be exchanged casually. But it also depends on the person. Huang Mingshan, Ge Dong, Lin Yinghao, Leng Fengxue and others basically do not have such problems.
In about an hour, Lin Yinghao completed preliminary and detailed calculations.
"Mr. Zhang, after preliminary calculations, electromagnetic rail ejection is feasible. In this way, we can also compress the size and weight of the rocket to less than 10 tons. But in this way, the rocket's own fuel can only provide 5 kilometers per second.
Extra speed.
But in order for the rocket to gain enough speed to enter space, the electromagnetic guide rail needs to provide a total amount of energy equivalent to an initial speed of 20.35 kilometers per second."
"That's not right, the orbiting speed is 25.3 kilometers per second, the surface rotation speed of the planet is 1.68 kilometers per second, and the rocket provides a speed of 5 kilometers per second. Then the guide rail only needs to provide a speed of 18.62 kilometers per second, which is enough."
"But if we send the rocket to an altitude of 1,500 kilometers, it will consume part of the potential energy. Calculated according to free fall and the gravity of the planet, the free fall speed can reach 1.73 kilometers per second."
Zhang Hao rubbed his brows and said, "Okay. The rail gun provides a speed of 20.35 kilometers per second. How difficult is it?"
"It's a bit big. But compared to the previous method of simply launching rockets, there is always hope for a breakthrough.
To lift a 10-ton rocket to 10.35 kilometers per second, approximately 300 million units of electricity are needed. This does not include the losses in the conversion process.
Our most excellent thermal power generation unit now has a power of 800,000 units of electricity per hour. That is 222 units of electricity per second.
According to preliminary calculations based on our current electromagnetic technology, taking into account the rocket's endurance, the rocket's maximum acceleration can reach 280 meters per square second.
To reach the speed of 20.35 kilometers per second, taking an integer, it takes 73 seconds.
To output 300 million units of electricity in 73 seconds, an average of 4.11 million units per second is required. Calculated based on the data of a unit of 222, 18,500 generator units are needed.
Based on the calculation that a generator set covers an area of 18x35 square meters, it requires 11.65 square kilometers of land to put it down.
The above figures are all theoretical values. The actual power conversion rate is about 80%, and it is impossible for the generator sets to be stacked together like building blocks.
The actual situation is that we need to build a super power plant of about 30 square kilometers, which requires at least 23,100 units. All power plants are in peak condition and execute all orders completely and without error.
Finally, it will be possible to send a rocket into space.
During this period, even a small fluctuation in numbers will ruin all efforts."
Zhang Hao opened his mouth when he heard these numbers.
I thought about the difficulty of launching a rocket, but I didn't expect it to be so difficult. This is simply an impossible task!
The total number of units in all thermal power plants of Dayang Group is only about 3,000. This alone has supported almost all of Dayang Group's industrial needs.
However, Lin Yinghao hadn't finished speaking yet, "Mr. Zhang, what I just talked about was the energy issue. There is also the more important issue of the launch rail.
The launch guide rail requires about 746 kilometers. The 746 kilometers of guide rail must not have the slightest flaw and must be perfect. There must be no dust, no air, and no slightest bumps in this process.
In addition, fixed rockets also need vehicles, and the vehicles also need to be accelerated simultaneously. The actual situation...may be much more complicated."
"Didn't you just say that the guide rail only needs 12 kilometers?"
"That one is calculated based on the weapon level. But the rocket is relatively fragile, and the endurance needs to be considered. Also, every time the guide rail is shortened by half, the required power unit will increase four times. Shortening the guide rail is never a good idea."
Zhang Hao closed his eyes, thought for a moment and suddenly said: "When the guide rail first starts to accelerate, there is no need to use electromagnetic technology. You can use steam ejection, or use explosives to accelerate. You can even use an external engine.
Wait until the speed reaches the chemical limit before enabling the electromagnetic rail acceleration.
Is the 10-ton rocket a bit big? We can study whether the weight can be further reduced.
By the way, aren't we studying the utilization of nuclear energy now? Maybe we can try to study the technology of nuclear power plants, etc.
As for the issue of guide rail accuracy, we will study it slowly in the future.
Now we finally have a direction.”
Having said that, Zhang Hao ended the conversation in a hurry. He had no choice but to be shocked by these numbers.
What are astronomical numbers? What’s more terrifying than astronomical numbers is ‘exploring astronomical numbers’!
23,100 generating units are still the latest thermal power generation technology of Dayang Group. Do you know how much it costs? Zhang Hao still remembers that a thermal power plant project was approved years ago, with 12 units worth 800,000 yuan, with a total budget of 300 million high-grade spiritual stones.
.This does not include the power grid, etc.
If we really need to connect 23,100 generating units in parallel, the cost of the power grid project alone would be an absolutely astronomical figure.
So this terrifying number directly made Zhang Hao make a judgment: purely using electromagnetic rail technology to launch rockets, just think about it, don't take it seriously!
It's so scary.
Also, 746 kilometers of guide rails? Previously, the scrap rate of weapons-grade guide rails was as high as 80%, and the accuracy required reached 10 micron level, which is 0.01 mm level.
If we make a 746-kilometer guide rail according to this requirement, Dayang Group will go bankrupt. But in fact, the space launch requirements will only be higher!
But the difficulty is only temporary, and now we finally have a direction.
The previous research was not in vain, but accumulated a wealth of science, technology and knowledge, especially a full understanding of gravity, air resistance, potential energy, planet rotation, orbit, atmosphere, formations, etc.
Especially in terms of formations and storage space technology, no one expected that instability would occur when the speed reached 16.8 times the speed of sound, which is 8.4 kilometers per second.
But you can understand it if you think about it. The space formation itself has "its own space resistance". When the speed reaches a certain level, the relationship between matter and space will become closer and closer, and problems are inevitable.
Of course, scientists from Ocean Group believe that advanced civilization must have a solution, but they have not found it yet.
Zhang Hao can only ask people to find answers from advanced civilizations on the one hand, including the Liuli Island spacecraft ruins that are still being explored. On the other hand, he has suspended the research on space formations, etc., which are too different from the actual requirements, and continues to research. In a short time,
It can only be a waste of financial resources.
In addition, we need to increase research on physical technology. At present, physical technology seems to be the most reliable.
In other words, the technology in formations is not incompetent. After all, it is not easy to support a cultivation civilization. However, Dayang Group does not yet have enough ability to completely solve the problems in formations. After all, these are left behind by advanced civilizations.
thing.
Dayang Group has started new research, but the research and launch of rockets are still continuing. On the one hand, it is researching technology, and on the other hand, it is also trying to catch rabbits and draw a pie for the allies of Dayang Group.
Although the current international situation is generally still within the Ocean Group and within Zhang Hao's expectations, it has gradually become somewhat out of control.
In a word: Dharma-level masters are too cruel!
Although the attack of nuclear bombs is terrible, such as the "Two Fatty" of Ocean Group, nuclear bombs are only one-time use. On the contrary, masters at the legal level can continue to destroy the theoretical lifespan of these masters for up to two thousand years.
Although the Dayang Group's nuclear deterrent is still effective, with this showdown between law-level masters, the influence of nuclear deterrence has dropped to a freezing point.
This, after all, is the world of cultivation!
Therefore, the Dayang Group should explore outer space as soon as possible, hoping to obtain breakthrough opportunities from outer space. The main practice method of the Dayang Group is "Zhou Tian Gong". According to the vague description of the exercise, the masters of the Dayang Group generally believe that
Outer space may help break through to a higher level.
What's the point of practicing "Zhou Tian Gong" and lying on the ground!
This statement is very reasonable, and Zhang Hao is also moved. However, this planet is a bit big, and it is not easy to break through.
However, Mr. Zhang has a lot to do. After arranging the aerospace mission, he will inspect the next phase of Dayang Group’s focus: standardization of practice.
Now the Dayang Group is going to establish a universal education and practice system in the Xihai Principality, and the ‘standard teaching materials’ compiled by the Dayang Group’s Dharma masters have entered the review stage.
It is foreseeable that in the new semester after June, schools across the country will be able to use new teaching materials. However, the training teaching materials need to be equipped with elixirs. At present, Dayang Group’s ocean medicine fields have begun to harvest, and Xinglintang has begun testing new elixirs.
production line.
Dayang Group is still under great pressure to supply elixirs to the whole country, and possibly even to some schools in Qixia Kingdom.
However, before all this was done, something happened on Liuli Island and the ruins of the spaceship.
