Chapter 475: Hall Advancement

"I have some information about the space shuttle, including its appearance design and basic flight control system. I will make a rough draft as soon as possible and hand it over to Mr. 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 they be finalized.

Of course, this is not a big problem, there are traces to follow. On the contrary, Wu Tong took on the most difficult part!

After the meeting, Cheng and his colleagues left first and immediately returned 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, accelerate the ions to generate thrust, and neutralize the ions in the plume…

Wu Tong stated her direction very directly in terms of research and development goals, which were to be able to take off and land freely like an ordinary airplane.

Controlled nuclear fusion is a miniaturized energy source that does not require an external fuel tank, an orbital aid, or a booster. The thrusters 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 thruster 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 share the same thinking with 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 name of the Hall thruster comes from its application of the Hall effect. It was invented by Professor Morozov next door in the mid-1960s. The existing design could not meet her research and development needs.

"It has a simple structure, high specific impulse, high efficiency, and most importantly, it is an electric thrust device. We have the card of controlled nuclear fusion in our hands. If we don't use electric thrust, wouldn't it be a waste of our inherent advantage?"

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 ring-shaped, 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 space vehicles in the future!

Wu Tong opened her notebook, and the first thing that popped up was undoubtedly a bunch of email reminders. Several well-known foreign journals such as the "Annals of Mathematics" and "Chronicle of Mathematics", as well as greetings and consultation emails from many domestic journals and schools... People's shadows and trees' barks, she has made a name for herself in the mathematics community, and these are 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 have given 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 various countries are giving her a headache and making her unable to sleep or eat.

However, going abroad is definitely impossible. In the final analysis, the curse of controlled nuclear fusion for 50 years has ended since she, and the Jinwu demonstration reactor project has been successfully ignited. Its significance is completely different from the previous overseas project. It is a real breakthrough. She is destined to stand in a special position, because this breakthrough is enough to affect the global pattern.

Science has no borders, but scientists have a sense of belonging. They belong to their country. Priority should be given to level, and the way to improve domestic strength must be something that is beyond doubt!

Compared to when she was just a scholar, her current travel is definitely more limited. This is not something that has 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 crossed over to fighter engines, ammunition, missile design, and warship engine research and development...

She had been mentally prepared enough!

China is a vast country with abundant resources. If she wants to go anywhere, she can feel at home. However, there is really no need for this. It is not because she is afraid of causing too much trouble to the people who protect her, but because, in addition to accompanying her family on trips, she prefers to explore the unknown sea of ​​knowledge and the limits of the universe!

Be at peace!

From the beginning to the end, she had no 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 two people's field of vision.

"This is your glorious testimony!" Mr. Wu's dazzling appearance attracted the attention of the world. Lu Xiao looked at the diagram and said, "Is this a plasma engine?"

The sketch was simple, but the structure showed its extraordinary qualities: the feed inlet, storage chamber, ionization chamber, nozzle... Lu Xiao saw the key points of the design at a glance.

"Boss Wu wants to take out the power chamber separately and design the plasma-emitting nozzles into Hall propulsion units, which are integrated behind the power chamber. By heating and applying voltage, the vaporized propellant can be ionized to form high-temperature plasma, which can be sent into the Hall propulsion unit connected to the ionization chamber?"

This is a unique and bold design that is very different from the current Hall thrusters. Lu Xiao is not surprised, as this is President Wu's usual style. Those ingenious research and development designs are the result of time and time again breakthroughs in scientific research that are very different from current ones. President Wu has already reached the top of the world, and the path forward was originally drawn by her to open up a new path.

Wu Tong nodded in agreement. As expected of CEO Lu, she could see the original intention of her design at a glance. "Yes, in theory, as long as the energy output is large enough, the power of the engine can be infinitely increased. Once small-scale nuclear fusion is achieved, we will have plenty of electricity to output energy!

I want to use this design to more efficiently handle the high-temperature plasma in the ionization chamber, eject it out of the engine, reduce the pressure on the combustion chamber, and at the same time neutralize it 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 whether such high-temperature facilities can be moved, the sheer size of the Jinwu controlled nuclear fusion demonstration reactor means that it cannot be used directly on a spacecraft. Safety and miniaturization are a must!
