However, it is not easy to make the two elements collide and merge with each other.
In nature, there is a repulsive force between elements. The only way to overcome this repulsive force is to increase the temperature and pressure of the elements, accelerate the speed and frequency of their movement, and make it easier for the elements to collide and fuse.
To achieve such high temperature and high pressure conditions, we must rely on two methods: one is the inertial confinement method, and the other is the magnetic confinement method.
The most common method of inertial confinement is to heat and compress hydrogen with lasers and particle beams to mix hydrogen and helium. If they are kept under high temperature and pressure for a long enough time, they will undergo nuclear fusion.
The core issues of this method are how to control the heating and compression process under high temperature and high pressure, and how to improve the energy conversion efficiency under high temperature and high pressure.
The magnetic confinement method uses a strong magnetic field to trap fusion-capable gases such as hydrogen and helium in a certain space, and then stimulates them into plasma through current or radio frequency, thereby causing fusion. This method also has some problems, such as how to establish a stable magnetic field and how to reduce plasma loss.
The Jinwu demonstration reactor proved that they had succeeded in achieving magnetic confinement.
On the road of experimentation, although they were crossing the river by feeling the stones, success is success, and they broke through the zero foundation. Although they dare not say that they have reached the state of having tried everything, they believe that they still have some good experience foundation in controlled nuclear fusion.
The management structure of the institute has never been Wu Tong's focus. Wu Tong just made a brief tour to confirm that the institute was operating normally and the new researchers were properly arranged. In order to live up to the enthusiasm of several colleagues, he went straight to the next topic, the preliminary discussion on the analysis of the launch plan of the Earth-Moon project.
Of course, putting management on the back burner simply stems from her confidence, as she's the core of all projects and will not tolerate any mismanagement in the management of her research institute. Therefore, rather than expanding into areas she's less skilled in, Wu Tong prefers to further maintain her strengths in her own specialized research field!
One force can defeat ten skills. At this moment, Wu Tong felt that she was quite suitable for this ancient saying.
"Teacher, Brother Lu, Academician He..." Wu Tong greeted each attendee one by one. They would be working together for a long time. Most of them had long been in sync through repeated collaborations, so there was no need for extraneous formalities. Wu Tong got straight to the point: "I've already agreed with the higher-ups. The future research direction of the 686 Institute of Advanced Technology will focus on three key areas: aerospace, energy, and strategic information technology. We will focus on developing technologies in these three areas!"
"This is a major theme and goal. Around this major direction, everyone can develop excellent projects and extend it. My recent focus, after considering it for a while, is on the miniaturization of controlled nuclear fusion and the research of aerospace propulsion systems!" Research and development without a goal is like a headless fly flying around aimlessly, a mess without any context.
Wu Tong has always been very particular about his research and development direction and goals. After determining the broad direction of his research, he selected two of these three areas as key research priorities.
After fully clarifying the R&D process, Wu Tong needed the support of her research team for experiments and real-world applications. However, before that, Wu Tong didn't want to overly concentrate resources and waste their time. Therefore, she was willing to allow these core R&D personnel to work on projects in their areas of expertise, perhaps even yielding unexpected results.
After all, no matter how capable she is, she is just one person, and what she sees is only from her own perspective. With collective efforts, everyone's perspective will be more comprehensive and clear.
"Miniaturization of controlled nuclear fusion and space propulsion?" As soon as these two R&D goals were announced, the entire conference room was instantly captivated. The breakthrough and success of the controlled nuclear fusion demonstration reactor project had proven to everyone in the world the exceptional R&D capabilities of Mr. Wu Tong.
No one thought that Mr. Wu's R&D goal was unrealistic. Instead, they immediately thought about how to achieve these two goals and what technology to use to realize them!
While working on their own projects offered more freedom, working alongside Mr. Wu was the true path to achieving significant progress. They were already familiar with Mr. Wu's R&D speed. Therefore, everyone was essentially on the same page. Were they working on their own projects? Of course they were. However, this was only to supplement the initial free time available under Mr. Wu's projects, serving as a secondary arrangement.
Their primary mission is to fully cooperate with Mr. Wu and create another miracle! No one, especially any R&D staff, can refuse the opportunity to create or witness a miracle!
"Currently, space launches are still mainly based on rockets.
Rockets apply the law of conservation of momentum. It should be noted that the internal energy of the system is different before and after launch. The newly added internal energy comes from the combustion of rocket fuel. The internal energy of the system has increased, and the mass of the ejected matter per unit time is relatively low, but the speed is fast. Therefore, under the action of the law of conservation of momentum, the rocket can accelerate its flight!
The current heavy-duty rocket thrusters resemble engines, designed to serve many purposes. Similar to the design principles of an engine, the rocket thrusters' pipes exhaust gases to propel the spacecraft through each stage of its journey! "Having immersed themselves in the aviation field for many years, both Lu Xiao and several aviation experts Wu Tong had collaborated with were naturally familiar with aerospace, a field that shares similar attributes."
Anyone can understand space rocket launches. Even if they don’t know everything about it, at least they understand the basics.
During a rocket launch, external booster rockets provide fuel to the rocket thrusters until the fuel is exhausted and then jettisoned. After that, powerful electromagnets enter the rocket thrusters to accelerate the ions to near the speed of light, providing the majority of the spacecraft's thrust.
Finally, in the final stage of the journey, the thrusters are responsible for adjusting the spacecraft into the planet's gravity, providing reverse propulsion to slow down the speed so that the spacecraft can safely enter the orbit synchronized with the planet.
To achieve all of these functions, current aerospace thruster groups must have a high degree of sensitivity for high-energy ion acceleration and be able to handle the hundreds of thousands of pounds of thrust generated by solid-fuel thrusters.
When we embark on the research and development of aerospace propulsion systems, our first consideration must be the ability to perform the functions required by the mass of the spacecraft and the principle of gravitational acceleration!"
