Considering that they may not have a professional and technical background, Wang Zhiwei made the content of the report as easy to understand as possible, mixed with some research and development experience, taking into account the interest and popularization of science.

This reminded him of his first year as a master's student, when he revised more than ten drafts in a row for a paper to be submitted to the famous academic journal Nature, and top journals like Nature not only required the forward-looking and advanced nature of the submitted papers, but also required that the content of the papers should be "storytelling". Eventually, he succeeded in swiping his face on Nature as a byline. Since then, he has added points to his natural skills in academic storytelling, and has frequently and successfully brushed his face in a number of high-impact academic journals. This kind of person has a special code: Xueba!

In fact, if it weren't for the momentary anger, Wang Zhiwei, who was favored by everyone, could have successfully completed his doctorate with a full scholarship, and even if he was unwilling to change his nationality and stay in the United States for development, any aerospace research institute in China would have opened its arms to him. Even if he does not complete his doctoral studies and returns to China early, he can still find a research institute willing to accept him. Therefore, his choice to join a private enterprise surprised many friends and classmates.

But there is a good saying: if a person drinks water, he knows whether he is warm or cold. The longer I stay with the company, the less I regret my decision. He likes the current research environment: complete resources and equipment, abundant R&D funds, de-administrative management, and even personal treatment far beyond that of research institutes.

The most important thing is that the technical information that the company has is amazing. Just those that his permission can browse can be said to be at the forefront of the industry. Although he was also puzzled about the source of these materials at first, he was more surprised: to be able to engage in professional research that he likes, and to be at the forefront of his peers, is it important to be at the forefront of his peers?!

The electric propulsion system project that Wang Zhiwei is going to report on today is his main research direction. This kind of technology that relies on electrical energy as power is also a research hotspot in the international aerospace community, and some products have been actually applied to spacecraft, but they are not yet mature and can only be used as an auxiliary.

Taking rockets as an example, the current mainstream products are still traditional chemical rockets, which generate high temperatures through propellant-catalyzed reactions, and the propellants are heated and ejected to form a propulsion in the opposite direction. The technology has matured, but bottlenecks are becoming more and more apparent: the proportion of propellant that needs to be consumed is too high, resulting in a high cost per unit of load in space. In the case of a 500-ton rocket, 300 tons of it is the amount of propellant, and the efficiency can be imagined.

If electric propulsion is used, an inert gas such as xenon is ionized with electric energy to form a plasma composed of ions and electrons, in which the ions are accelerated under the action of an electric field to produce thrust. The pros and cons of the electric propulsion system are obvious, and the biggest advantage is that for the same space mission, the raw materials required by the electric propulsion system are only about 10% or less of the chemical methods used, and the accuracy and safety are relatively high. The most fatal disadvantage is: the thrust is too small, and the maximum thrust of the electric propulsion system parameters that have been disclosed in the world is also within 100 Newtons.

What is the concept of 100 Ox? In Earth's gravitational environment, the gravity of a person with a mass of 1 kilogram is about 9.8 N, which means that only 10 kilograms of weight can be sent into space using the most advanced electric propulsion system known to date. Even though in some top laboratories, electric propulsion systems with stronger thrust should have been developed, but compared to the hundreds of tons of thrust that can be achieved by a single-engine chemical rocket engine, it can only be said hehe. Therefore, the electric propulsion system currently used in space vehicles is generally used in conjunction with the gravityless space environment.

There are only two ways to make electric propulsion truly replace chemical propulsion, one is to greatly increase the thrust of the electric propulsion system, and the other is to continue to reduce the consumption of the electric propulsion system. The content of Wang Zhiwei's report today will be a leapfrog development and progress for the electric propulsion system.

Chen Wenhao sat on the side of the long table in the meeting, listening to Wang Zhiwei talking eloquently on it, and he already knew what he was going to report next. The basic technical data of the experiments carried out by the project team are based on him, and the relevant technology transmitted by Konishi is collated, and under the existing conditions, the thrust of a single electric propulsion system can exceed 200 tons.

If you want to go up, alien technology has never been tried, and electric energy has not been experienced for a long time in the history of the development of alien technological civilization. According to Konishi, the energy they used for the longest time in the primitive era was nuclear fusion, and now they use the energy of the cosmic space layer, which the earth civilization does not even have a concept of.

Even so, although it is not as good as the most advanced liquid oxygen kerosene engine or liquid hydrogen liquid oxygen engine that can reach more than 500 tons of thrust, it is close to the index parameters of the most advanced hydrogen and oxygen engine. You know, the hydrogen-oxygen engine is the first choice for heavy-duty launch vehicles as the upper stage engine today.

And according to this technological line, the size and weight of the electric propulsion system under the same thrust will be only a quarter or less of that of other space engines. So, it doesn't matter if the maximum thrust is almost a bit, just install a few more.

Wang Zhiwei has completed the content of science popularization and foreshadowing at this time, and entered the core of the experimental results introduction, "The VI type small electric propulsion system trial-produced in the laboratory has successfully achieved a thrust of 500 kilograms, and according to the data model, we are sure to double the thrust of the final product, and of course the weight and size of the propulsion system will become larger." ”

"We've increased our thrust by a factor of 100 compared to mainstream technology, which means that our electric propulsion technology is far ahead of the rest of the world. However, according to the technical information provided by the company, there is still room for significant improvement in thrust. But this requires a lot of experimentation. I request that the company can provide sufficient R&D funds and material support for the project team. The goal of the next stage is to increase the thrust by more than 10 times on the existing basis. ”

Chen Wenhao held his chin in his hand, thought about it and estimated: At present, it has reached a thrust of about one ton, although it is still much lower than the theoretical value, but it has left the earth technology far behind. In just a few months, the project team of several people was able to absorb the technical data of the alien civilization to this extent, and the progress was still good. Technical information is not an in-game skill book, and you can learn it automatically with a single click. Although the data points in the right direction, the steps and details need to be tested and mastered by the project team through a lot of experiments. According to the current progress, it is still expected to have a thrust of more than 100 tons in the short term.

Thinking of this, Chen Wenhao made a decision, "Thanks to the efforts of all the researchers in the electric propulsion project team, in view of the results that have been achieved, I decided to allocate another 3 billion yuan of R&D funds within the company to use the project." ”

"The rewards for researchers should be completed and distributed as soon as possible in accordance with the promulgated reward and punishment system."

"The project team members also need to arrange manpower in the near future to be familiar with the company's intelligent production workshop in order to design a large-scale production plan in the later stage."

……

Chen Wenhao issued a series of instructions in an orderly manner, and the responsible persons of his own relevant departments answered the orders. Chen Wenhao has always been only responsible for strategic and framework work, and rarely interfered in the details of the work, but this exception allows everyone to see the importance he attaches to this project.

For them, today's debriefing meeting has been successfully concluded, the achievements have been affirmed, and the work has been supported, which can be described as a bumper harvest.

The other executives have stayed, and Chen Wenhao has spoken to discuss the commercialization of electric propulsion technology with them.
