Chapter 678: The funding is down!

? The development history of the space shuttle can be said to have a long history.
After the United States completed the Apollo program in the 1960s, it focused its R & D efforts on the "multiple launch and simple maintenance" space shuttle. In this space race, naturally, the Soviet Union followed closely behind, and successively produced three space shuttles such as the Blizzard and the Little Bird, and achieved certain results.
In this context, China is naturally unwilling to lag behind, and corresponding plans have been followed.
For example, the original project code 863-204, also known as the "sky and earth round-trip transportation system", in the early days of the project bidding, domestic space experts had a long-running dispute over the "space shuttle" issue. Even the voice of support for the space shuttle once prevailed.
However, just when everything seemed to settle, the report was sent to Mr. Qian, who had already retired to the second line.
After reading the report, Mr. Qian commented only nine words on it, and it was these short nine words that completely changed the technical route of the space shuttle that was almost nailed down, and also changed China ’s aerospace industry. The future looks.
"The case of the spacecraft should also be reported to the central government."
Looking back now, it was undoubtedly correct to make such a choice at that time.
The space shuttle is not as glorious as it may seem. Even two superpowers with "power in the country" can hardly support humanity's dream of freedom to fly back and forth into the sky.
Take the United States as an example. The design life of the Columbia is 20 years / 100 launches, but the total number of launches of all five U.S. space shuttles barely exceeds one hundred, and the cost of each launch and maintenance is also very high. Estimates at the beginning of the design.
The Soviet Union was even worse. Three space shuttles were launched once. After the 1990s, they were unable to fly. One of the test aircraft was bought by Germany and placed in a museum.
Instead of tossing like this, it is better to simply use rockets and study how to recover the secondary rockets. The cost may not be much more expensive than the mature space shuttle technology.
However, times are always changing.
If we look at the problem from the perspective of development, any problem can find a solution to the problem.
Space Shuttle Assembly Center.
Standing next to the industrial robot, the gloved land boat picked up a metal bottle-sized metal cylinder from the plastic basket, weighed it in his hand, and moved closer to the port of the metal cylinder, along the The smooth metal surface looked carefully.
"How do you feel like two full laps?"
A bunch of bubbles popped up on the screen of the next CNC machine tool terminal.
Xiao Ai: [Sorry host! This is already the smallest size that Ai can do ... QAQ]
Lu Zhou: "Don't do this, I didn't blame you ... you have done a good job."
Xiao Ai: [Really? 0.0]
"……Ok"
Xiao Ai: [Happy! φ (≧ ω ≦ )?】
Lu Zhou: "..."
Holding in his hand at this moment is an enlarged version of the Hall thruster on Wreck III, which is also the limit that this CNC machine can process.
Lu Zhou did not try to make Xiao Ai smaller without sacrificing performance. However, starting from the current volume, each time the maximum cross-sectional diameter is reduced by 1mm, not only the overall processing difficulty will be geometric. Growth and stability of the propulsion unit will also be severely affected.
However, even if it is difficult to completely restore the technology on Wreck III, this imitation is quite stubborn.
An engine port with a diameter of 1.32 meters can integrate about 200 Hall propulsion units. By pressurizing and rectifying the plasma xenon gas in the ionization chamber, it can backwardly eject a plasma plume accelerated to a thousandth of the speed of light, thereby generating the largest 200KN thrust.
The thrust of a single engine is 200KN, and the five engines add up to 1000KN.
Even if it is calculated with a full load of 50 tons, it can obtain acceleration of nearly 1G under the gravity environment. Although it is faster than chemical rockets in acceleration, its advantage in specific impulse makes it possible to put itself into low-Earth orbit without carrying heavy working fluids.
The only trouble now is that a 100M fusion battery is probably only enough to meet the needs of an X-type Hall thruster.
If he wants to meet the energy consumption of such a Hall thruster, he must further upgrade the power of the fusion battery.
"It seems that the power of the fusion battery must be increased to more than 500M ... preferably 1000M," staring at the Hall propulsion unit in his hand, Lu Zhou thought, "and the power management system also needs to be improved ... … Is there any way to integrate the ionization chambers of the five engines? Or simply get a larger Hall thruster with more propulsion units. "
The Hall propulsion unit was put back into the plastic container and fixed. Lu Zhou turned away from the assembly center's factory building and came to an office in the main building next to him. He found the technical director of the Starry Space Shuttle Assembly Center, Hou Guang.
Speaking of this waiting light, he is also a bull.
As an old professor who has participated in the 863-204 project, although he was an intern as a trainee and engaged in the design of the space shuttle, he still has accumulated a wealth of research experience in this field. He later served as a professor at Beijing University of Aeronautics and engaged in research in the field of aerospace.
Theoretically speaking, such a cow is difficult to dig. However, after learning that the company's boss is always Lu Zhou, after Lu Zhou planned to build a space shuttle, he didn't even discuss the treatment in detail, so he took it without a word. The offer of Xingkong Technology rushed to Jinling the next day.
More than a month has passed since the day he assumed the post of technical director.
For his work, Lu Zhou has always been satisfied.
How to design this space shuttle, after all, is not his expertise. It is better to leave such professional matters to professional personnel.
"... I have carefully studied the design of the space shuttle. Considering the size of the energy supply components and the electric propulsion system, more than 40% of the space must be redesigned."
Lu Zhou: "What concept is more than 40%."
Hou Guang thought for a while and gave a clearer statement.
"Probably backwards from the wing position, all have to be redesigned."
Lu Zhou nodded.
"You are an expert on the space shuttle. Just follow what you say. In addition, based on your experience, I hope you and I will simply evaluate how much the entire project will cost?"
Hou Guang groaned for a moment, then spoke.
"Conservatively estimated at $ 1 billion ... Of course, before the new design plan comes out, no one can say how much it will cost."
$ 1 billion ...
In terms of the cost of the space shuttle, this price is not expensive. After all, the Columbia spent 2.5 billion Americans from research and development to construction, and it was 2.5 billion decades ago. It can be built for 1 billion US dollars, which is also a large part of the cheap design that has been completed before the 1990s and the millennium, and this assembly center can process most of the parts, just supply Basic raw materials are sufficient.
However, although it is ready to burn money ...
The cost of one billion US dollars is really beyond his budget.
Thinking of this, Lu Zhou couldn't help worrying about money for a while.
Want to sell a bit of East Asian Power stock?
Although it is not listed on the market, it will definitely sell if you sell it. After all, individuals can see the future potential of this fusion industry giant. However, the construction of the Fuxi Reactor in Daya Bay has just begun, and the Southeast Asian Power Grid project has just completed one phase. At this time, it is too much of a loss.
Should we borrow money from the bank?
However, this is an aerospace project. This kind of investment has a long investment cycle, and you can't see projects with obvious profit expectations. How can it be so easy to borrow?
Just as Lu Zhou hesitated ~ EbookFREE.me ~ the door knocked suddenly.
Withdrawing the divergent thoughts, Lu Zhou looked at the door and said.
"Come in."
The door opened and saw the secretary of the director of the assembly center's office appeared at the door.
It seemed that Lu Zhou was not here. The secretary looked at Lu Zhou for a moment, but she gave her a slight hesitation, but then a surprised expression appeared on her face.
"Professor Lu!"
Lu Zhou: "What's up?"
In an excited tone, she continued.
"The funds we applied to the space agency some time ago have been approved!"
