After 11:30 in the evening, the number of flights at Shangjing International Airport also decreased significantly. Lu Yi's special plane finally stopped going to line up and had a free runway to arrange takeoff.

"For a while, I'll find a place to sleep on my own. I won't be able to arrive in Yangcheng at around 2 a.m.."

After the roar and bumps during the takeoff phase of the plane passed, Lu Yi took out the airline's prepared air bento in advance and handed it to Wei Hong. Then he took the portion for Zhang Qing and Lin Meng and made 3 cups of espresso.

He previously sent an emergency problem to the nuclear fusion demonstration reactor project that Beihang mentioned was not a joke, but it was really a matter, but it was not a big problem. It should be handled during the journey to Beijing to Yangcheng.

Wei Hong, the young man who was in Beihang just now, smelled the smell of coffee in the air, and saw Lu Yi and others opening their laptops to quickly divide the labor, dealing with problems while eating, and then looked down at the air bento that didn't taste very good in their hands, and asked in a daze: "General Manager Lu, are you planning to stay up all night?"

"If there are urgent problems in the project, you must first deal with it. If you can't sleep, you can do project planning for aerospace engines. In a few days, a group of researchers will be assigned to you.

You are fully responsible for the project research. You need to control the direction and progress of the entire project and assign division tasks to your fellow researchers.

There will be a dedicated team to help you deal with administrative and life matters. If you have any problems, just raise them.”

Lu Yi ignored Wei Hong's dazedness and briefly said what he wanted to do next.

After this period of development, the laboratory has formed a relatively complete operation system. Simply put, the core of the laboratory is scientific research. This group of researchers only needs to do research with peace of mind. The team led by Xu Ying will help deal with other things.

“Does there any professional material research in the laboratory?”

After all, he is a monster with potential of 96.8. Wei Hong quickly entered the state when he heard Lu Yi's words and asked: "This aerospace engine does not require fuel propellant, it has requirements for the thermal expansion coefficient of the propelling working fluid, and the nozzle material also has relatively high requirements."

"There is a top materials laboratory. I will introduce Hu Feng to you tomorrow. You can discuss the issues involving materials yourself."

Lu Yi smiled. In the laboratory positioning, the materials laboratory is a brick and can be moved wherever it is needed.

Materials themselves serve industry and technology, and Lu Yi is not worried about the medium with high thermal expansion coefficient required by this engine.

The expansion of the gas is proportional to the temperature. Taking hydrogen, which is easier to obtain, as an example, the volume expansion coefficient of hydrogen is 3.66×10^-3, which means that when the temperature changes by 1 degree Celsius, its volume will change by 3.66 per thousandth.

As long as the power and energy density of the nuclear fusion reactor is high enough, the amount of waste gas emitted by temperatures up to 100 million degrees Celsius per unit time is relatively large, the temperature of liquid hydrogen will be instantly increased to a very high level, and the volume will expand greatly in an instant, thereby generating terrifying expansion pressure.

When this part of the expansion pressure acts on the conical or bell-shaped inner wall of the engine nozzle, the pressure is converted into thrust and the temperature will drop. This is the entire work process.

Lack of accurate simulation operations with supercomputers, Lu Yi and Lin Meng made a rough analysis on paper and pen on the way to the airport.

A small fusion reactor with one-tenth of the power of the demonstration reactor is now under construction, combined with liquid hydrogen as the expansion propulsion work fluid. The consumption of the propulsion work fluid has decreased by between 64 and 69 times compared with the fuel consumption of the rocket engine.

The original Fat Five required more than 500 tons of propulsion fuel to send 10 tons of material to the geosynchronous orbit. If it was replaced with this kind of engine, it would not take 8 tons.

Of course, lower propulsion fluid consumption also means that the output power of a single portion of propulsion fluid will be higher, which will also cause greater pressure on the material. This is the focus of this project in the next project.

"General Engineer Lu, I want to ask a question..."

At around 1 a.m., Wei Hong didn't sleep. Seeing that Lu Yi had no intention of going to bed directly after dealing with the problem, he walked up to ask hesitantly.

"What's the problem?" Lu Yi looked at Wei Hong with a strange look.

Wei Hong struggled for a while and finally asked: "You know a lot. I want to ask if our country has a hydrogen bomb miniaturization technology, which is an ultra-small hydrogen bomb with an equivalent of hundreds of tons."

"What are you doing inquiring about this?" Lu Yi narrowed his eyes slightly, and his hands quietly turned around his watch, with a button on it.

"I don't mean anything else. If we have the technology of miniaturizing hydrogen bombs and can produce hydrogen bombs with an equivalent of less than 500 tons, my idea of ​​having an aerospace engine seems to be feasible."

Wei Hong noticed something was wrong with the atmosphere and hurriedly defended with a pale face.

"What's the idea?"

Lu Yi still did not relax his vigilance. As long as he pressed the button on his watch, the security personnel in another cabin could come as soon as possible.

"Sumi's Cold War Orion Plan!"

Wei Hong gritted his teeth and said: "The previous engine can greatly reduce the cost of getting rid of the planet's constraints and entering space, but due to the expansion speed and energy density of the propulsion work fluid, its acceleration is not very good.

But if there is an ultra-small hydrogen bomb, referring to the engine planned by Orion back then, the engine's thrust and acceleration can eventually reach an amazing level, making interstellar navigation no longer a dream.

It can accelerate the spacecraft to an extremely high speed in a very short time, and can directly conduct interstellar navigation without experiencing the planet's gravitational acceleration. It is not a problem to reach Mars within 3 days, and even the material protection ability is improved. This speed can continue to accelerate!"

"Orion Plan? The engine that throws nuclear bombs into the butt of the spacecraft and uses the nuclear bomb explosion as thrust?"

Lu Yi was a little stunned. He suddenly wanted to pry Wei Hong's head open to see if the brain structure of a person with a potential of 96.8 will be different from everyone else's, but the head of a lunatic.

"How to solve the problem of nuclear radiation pollution? Also, hydrogen bombs need to explode in the nozzle like the engine we are currently studying, so that they can generate thrust. In this way, how to solve the high damage to the material caused by the explosion of the hydrogen bomb to release neutron radiation?

How to solve the instantaneous energy impact generated by the hydrogen bomb explosion exceeds the upper limit of the material? How to solve the ultra-high temperature generated by the hydrogen bomb explosion?"

Out of respect for a scientist whose systematic score was as high as 96.8, Lu Yi rubbed his head with some headaches and asked a few questions.

This is not a high-potential scientist, he is clearly a lunatic.
