    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.

    ???????????????????????????????????????????????????????????????????????????????????????OUT OFF off these formulas, data, etc., Zhang Hao can only barely get a rough 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.  Especially mathematics in this world is inextricably linked to spiritual practice, Bagua, Xiangshu, etc.

    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 there will not be much Zhang Hao's intervention 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 point in a general direction.  For example, space exploration, rocket technology, electromagnetic rail technology, etc.  But more specifically, Zhang Hao can no longer intervene.

    ??????????????????We are calculating and discussing at the same time.  Then he contacted Ge Dong by phone to obtain relevant data.

    Scientific research data cannot be exchanged casually.  But that 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. 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, "Okay. How difficult is it to provide a rail gun with a speed of 20.35 kilometers per second?"

    "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, etc.

    Our most excellent thermal power generation unit has an hourly power of 800,000 units of electricity per hour.  That's 222 units of electricity per second.

    According to our current preliminary calculations of 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.

    It outputs 300 million units of power in 73 seconds, requiring an average of 4.11 million units per second.  Calculated based on the data of 222 units, 18,500 generating 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 numbers above 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.

    Actual situation, we need to build a super power plant of approximately 30 square kilometers, requiring at least 23,100 units. All power plants are in peak condition and execute all orders completely 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.  "

    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.  This is simply an impossible task!

    The total number of units in all thermal power plants owned by Dayang Group is only about 3,000.  This alone has supported almost all of Dayang Group¡¯s industrial needs.

    However, Lin Yinghao hasn't finished speaking yet, "Mr. Zhang, what I just talked about is the energy issue. There is also the more important issue of the launch rail.

    The launch rail requires approximately 746 kilometers.  The 746 kilometers of guide rail must be flawless and flawless.  This pastThe exercise is "Zhou Tian Gong". According to the vague description of the exercise, the masters of Dayang Group generally believe that going to outer space may help to break through to a higher level.

    What¡¯s the point of practicing "Zhou Tian Gong" and lying on the ground!

    This statement makes sense, 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 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 can be predicted that in the new semester after June, schools across the country will be able to use new teaching materials.  But the training materials need to be equipped with elixirs.  At present, Dayang Group's marine medicinal fields have begun harvesting, and Xinglintang has begun testing a new medicinal pill production line.

    Dayang Group is still under great pressure to meet the supply of elixirs for the whole country and possibly even some schools in Qixia Country.

    However, before all this was done, something happened on Liuli Island and the ruins of the spaceship.  (Remember the website address: www.hlnovel.com
