"I have some information about the opposite space shuttle, including its exterior design and basic flight control system. I will make a rough draft as soon as possible and submit it to General Wu for review!" Lu Xiao then determined the task for himself, including the detailed control system, energy source and thrusters... Only after all these were finalized could the final decision be made.
Of course, this wasn't a big problem, as there were traces of progress. On the contrary, Wu Tong single-handedly shouldered the most difficult task!
After the meeting, Cheng and his colleagues left first, immediately returning to their respective tasks. Lu Xiao stayed behind, "Boss Wu, do you want to achieve your goal in one go? Do you want to conquer the Hall effect thruster?"
Hall effect thruster, Hall effect thruster!
In the thruster, the propellant is accelerated by an electric field. The Hall thruster confines electrons in a magnetic field and uses the electrons to ionize the propellant, accelerating the ions to generate thrust and neutralizing the ions in the plume.
Wu Tong stated her direction very directly when it comes to research and development goals, which is to be able to take off and land freely like an ordinary airplane.
The miniaturization of controlled nuclear fusion is an energy source. It does not require an external fuel tank, an orbital assist vehicle, or a booster. The thruster must have sufficient starting power to support the space shuttle to break through the gravitational limitations and penetrate the atmosphere.
The most advanced concept of propulsion is the Hall thruster!
"The one who understands me is Mr. Lu!" Wu Tong smiled. This is the partner who can keep up with her pace and has the same thinking as her!
She nodded, leaned back in her chair, and turned the recorder in her hand. "It's a Hall thruster, but it's not just the current Hall thruster!"
The Hall thruster, named for its application of the Hall effect, was invented by Professor Morozov in the mid-1960s. Existing designs could not meet her research and development needs.
"It has a simple structure, high specific impulse, and high efficiency. Most importantly, it's an electric propulsion system. We have the card of controlled nuclear fusion. If we don't use electric propulsion, wouldn't it be a waste of our inherent advantages?"
The working principle of Hall thrusters is similar to that of ion thrusters, both of which generate thrust by accelerating ions through electric fields.
However, the structure and ionization method of the Hall thruster are more advanced. Its magnetic field is annular, which can prevent positive ions from colliding with the anode chamber and produce closed-loop Hall drift, further confining and accelerating the plasma.
This design gives the Hall thruster significant advantages in thrust output and energy efficiency, and it will surely become one of the preferred propulsion devices for spacecraft in the future!
Wu Tong opened her laptop, and the first thing that popped up was undoubtedly a flurry of email alerts. Several well-known international journals, like the Annals of Mathematics and the Chronicle of Mathematics, as well as numerous domestic journals and schools... greetings, inquiries... She had made a name for herself in the mathematical world, so these were inevitable.
She had served as a reviewer for these journals before, but was too busy working on the Jinwu controlled nuclear fusion demonstration reactor later, so she turned down most of the review invitations.
However, these journals still send her holiday greetings regularly, want to commission articles from her, invite her to go abroad for academic exchanges, and offer her formal appointments, guest invitations, and honorary invitations.
She also exchanges emails with scholar friends she knows... She is very grateful that these simple scholar friends have not excluded her from the academic community even when other countries are giving her a headache and making her unable to sleep or eat.
However, going abroad was definitely out of the question. Ultimately, the fifty-year curse of controlled nuclear fusion had ended with her, and the Jinwu Demonstration Reactor Project had successfully ignited. Its significance, unlike that of the previous overseas project, was a true breakthrough, and she was destined to occupy a special position, because this breakthrough was enough to influence the global landscape.
Science has no borders, but scientists have a sense of belonging. They belong to their country. Prioritizing hierarchy must be how to enhance domestic strength. This is beyond doubt!
Her current travel is definitely more limited than when she was just a scholar. This is not something that just started now. Wu Tong has long been accustomed to it. From her first step into the materials industry, she started with the research and development of fighter materials, and then expanded into fighter engines, ammunition, missile design, and warship engine research and development...
She had been mentally prepared enough!
China is vast and rich in resources. If she wanted to go anywhere, she could feel at home. However, there was really no need for that. It wasn't because she was afraid of causing too much trouble for her protectors. Instead, besides accompanying her family on trips, she preferred to explore the unknown sea of knowledge and the limits of the universe!
Be at peace!
She never had any desire to go abroad.
"Mr. Lu, I'm sorry to have embarrassed you!" After clicking on the reminder notification, Wu Tong opened the software, and a simple structural diagram appeared in the eyes of both of them.
"This is your glorious testimony!" Mr. Wu's dazzling appearance attracted the attention of the world. Lu Xiao looked at the diagram and asked, "Is this a plasma engine?"
The sketch was simple, but the structure showed its extraordinary qualities: the feed port, storage chamber, ionization chamber, nozzle... Lu Xiao saw the key points of the design at a glance.
"Boss Wu wants to separate the power chamber and design the plasma-emitting nozzles into Hall propulsion units, integrating them behind the power chamber. By heating and applying voltage, they can ionize the vaporized propellant, forming a high-temperature plasma that will be fed into the Hall propulsion units connected to the ionization chamber?"
This is a unique and bold design that is very different from the current Hall thruster. Lu Xiao is not surprised. This is President Wu's usual style. Those ingenious research and development designs are derived from time and time again, which are very different from the current scientific research breakthroughs. President Wu has already reached the top of the world. The path forward is originally drawn by her to open up a new path.
Wu Tong nodded in agreement. As expected of President Lu, she immediately understood her design intent. "Yes, theoretically, as long as the energy output is large enough, the engine's power can be increased infinitely. Once small-scale nuclear fusion is achieved, we'll have ample electrical energy for output!"
I want to use this design to more efficiently handle the high-temperature plasma in the ionization chamber, ejecting it out of the engine to reduce the pressure on the combustion chamber. At the same time, it also needs to be neutralized to prevent the ejected plasma plume from being sucked back into the ionization chamber! "
"This is just a preliminary idea. After all, no matter how the Hall thruster is designed, the amount of electricity required will be a terrifying number. In the final analysis, we still have to return to the most critical issue, small-scale nuclear fusion!" Wu Tong smiled and spread her hands. This is her ultimate goal of small-scale nuclear fusion. Clean, huge and sustainable energy supply is the foundation of her design and research and development!
Putting aside the question of whether such a high-temperature facility can be moved, the sheer size of the Jinwu controlled nuclear fusion demonstration reactor means it cannot be used directly on a spacecraft; safe miniaturization is a must!
