0152 The technology tree is getting weirder(1/2)
On the 35th, Xia Ming began to discuss the energy issues in the second phase with Xiaotang.
The first phase of the "fuze" detector will arrive at Zhishen Star on D132. This detector with a total weight of only 500 kilograms is consumed by nearly 90% of its weight on the engine and power supply. The detection equipment is only cameras and LED searchlights. The communication system is entirely dependent on Qianyan Mini. The risk is very high. In fact, it is just to try your luck first.
The real hope is placed on the second stage of the "lightning-tube" detector. If the 10 MW V-MR can be successfully developed, the total weight of the "lightning-tube" can reach 4 tons, and then the detection and communication equipment will have a greater margin.
The "Thunder-Guan" plan is to arrive at Zhishen Star on D160. Its design speed is faster than the "Fuse", and it is expected to take only 50 days. That is to say, on D90, 23 days after the "Fuse" sets off, the "Thunder-Guan" will follow the sky.
However, the bottleneck of the "thunder tube" is still in terms of energy. Solar cells cannot meet the appetite of 10 MW VA and can only be used as auxiliary energy.
Xia Ming has been devoted to various cutting-edge energy technologies during this period, and has finally come up with the energy system design of the "thunder-tube" detector.
However, when Xiaotang heard this noun, he looked suspicious.
“Flywheel battery?”
“Yes, flywheel battery!”
Xia Ming explained: "The energy system that Qianyan and I imagined is like this. Solar cells, supercapacitors and flywheel batteries form a joint system, with flywheel batteries as the core and complement each other. As long as the total detector weight remains within 4 tons, the energy of this solution is enough."
Xiaotang was silent for a while, probably using Pei to find information to confirm this technology. Then she frowned and said, "This flywheel battery needs a lot of improvements."
Xia Ming nodded: "It is indeed a huge challenge, but compared to other technologies that require new principles or newly discovered technologies, flywheel batteries still have great potential. The technical difficulty lies in the materials."
Xiaotang pinched his chin and squinted his eyes: "It's interesting, the gallium nitride has almost been done, I'll start to solve it."
Flywheel battery, referred to as fess, is indeed a very interesting energy storage technology.
Unlike nuclear and chemical batteries, flywheel batteries are mechanical energy storage, and their technical ideas are very simple.
As we all know, power plants rely on rotors to cut magnetic lines to generate current, and the mechanical energy of the rotor becomes electricity. Hydropower plants rely on water flow to drive the rotor. Thermal power plants rely on the thermal energy of medium and oil or natural gas to drive the rotor. Nuclear power plants rely on the thermal energy of boiling water to drive the rotor by nuclear fission.
The flywheel battery treats the flywheel as a rotor. When charging, the rotor rotates rapidly and converts electrical energy into mechanical energy. When discharged, the rotor converts mechanical energy into electrical energy. The DC motor is reversible and can generate and discharge electricity. The principle is simple and the structure is simple.
However, seemingly simple technology has many thresholds, first of all, friction resistance, secondly, material, flywheel must reach at least tens of thousands per minute. Generally, materials cannot withstand it.
This concept was proposed in the 1970s. Because of these two difficulties, it only became a reality in the past few years, and it took more than 40 years.
Flywheel batteries are now very mature. The ups field is the most widely used. In other fields, such as electric cars, it has also been used very early. Flywheel batteries are installed into the car's wheels and absorb the energy of wheel braking, which is already the standard configuration of many luxury cars. Porsche's F1 racing cars also use flywheel batteries as auxiliary power, and the American Nasa also has flywheel batteries on the space station.
The most eye-catching application is the aircraft carrier. Ford's electromagnetic catapult system has flywheel battery components. Huaxia's electromagnetic catapult system also follows this route because its power density is higher than that of supercapacitors. As the saying goes, it has strong explosive power.
But even now, flywheel batteries still have great defects, and the main problem is friction loss.
Flywheel batteries that are widely used now are operated in vacuum. Even so, the daily natural loss rate is more than 10%. Once discharged, the loss will be more serious.
However, superconducting technology has significantly improved flywheel batteries. Using the superconducting principle to stabilize the flywheel and remove the bearings with direct contact, the friction loss is reduced a lot. Flywheel batteries based on superconducting magnetic levitation have a natural loss rate of less than 2% per day.
Another difficulty is that the flywheel itself must be faster to store higher energy and the mass must be lighter. It not only reduces friction (vacuum is not absolute), but also allows the entire battery to adapt to movement to a higher margin.
In a motion state, it is difficult for the flywheel to remain stable. If it is in a superconducting environment, the superconducting electric field generated by superconducting magnetic levitation will stabilize the state of the flywheel and prevent it from moving randomly. If the flywheel is light enough, the stability will be very strong.
However, superconducting technology has not yet entered the field of room temperature and requires a set of cooling equipment. The volume and energy consumption of cooling equipment are not small, so superconducting flywheel batteries have not yet been able to enter daily applications.
However, for Aerospace, these two problems are not prominent.
Whether it is materials or superconducting, they happen to be Xiaotang's professional field. She roughly estimates that the flywheel's speed must be increased ten times and the loss must be reduced ten times to meet the needs of the "thunder-tube" detector, and both of these points fall on the materials.
"Come on, Qianyan, get crazy." Xiaotang muttered to Qianyan in the laboratory.
"Are you talking about crazy workload or spreading thinking? In the former, my average load has reached 27% in the past month, and the number of thinking patterns I have been exposed to has increased to 72, which has made my growth faster. But whether I can increase my load does not depend on me, but on you."
"If it were the latter, I'm sorry I can't do it. Humans rely on intuition to do spew thoughts, while I can only rely on random numbers, which makes no sense."
Qianyan's serious correction made Xiaotang smile bitterly and shake his head. After all, it was just a simulated mental model.
"It should be light and high intensity. Is this intentional?"
When Xia Ming talked about the flywheel battery, Xiaotang thought of an answer, but she couldn't believe it, it would be such a coincidence?
"Qianyan, unblock the technical information about graphene."
It was discovered that gravity was smashed by apples, that penicillin was careless, and that graphene was boring. Although this is a fairy tale of the music style, it cannot be denied that the importance of luck to scientific research.
Xiaotang was too lazy to ask if anyone was favoring her. She only knew that the unexpected gains from the previous stage had become the best choice for this stage.
Yes, what else can be lighter and stronger than graphene?
Of course, she could not use single-layer graphene as a flywheel directly, which would be too light and the strength would definitely not be enough. More importantly, the flywheel material must be permanently magnetized. Graphene has no magnetism, so she has to find a way to magnetize graphene, but it does not affect performance. Then use nanotubes woven graphene as fibers and mix them with polymer carbon fibers to make a flywheel.
How to magnetize...
"I searched for relevant academic papers and found that graphene can be permanently magnetized by yttrium iron garnet. Yttrium iron garnet is an insulator and will not affect the electronic properties of graphene."
Qian Yan's prompts for Xiaotang to come to the club, just like a fairy voice. This is the benefit of Qian Yan, an omniscient research consultant.
She asked Qianyan again whose paper was. Qianyan said: "University of California, Professor Shi."
Xiaotang snapped his fingers: "I have heard of him several classes, it's great!"
I am still a senior from the same school, so I crossed this threshold for a few thoughts...
While Xiaotang was buried in the laboratory, Xia Ming was pressed to the bed by Liluo.
Of course it is not to roll the sheets, but Lilo's human nerve model has achieved initial results, so I asked Xia Ming to do the experiment.
The model was passed to Xia Ming's brain through QN, and after being deployed by Xia Xiaoyan, a panel appeared in Xia Ming's ar vision.
Strong: Waiting for testing...
Reaction: To be tested...
Sensitive: To be tested...
Physical constitution: to be tested...
Dexterity: To be analyzed...
Endurance: To be analyzed...
Status: To be analyzed...
This is a property panel.
Xia Ming almost choked by saliva: "Hey! When will it be changed to a system or game text? This style is wrong!"
"The first three items are the measurements of your nervous system, the last three items are the measurements of your muscle and bone conditions related to the nerves, and the last one is the evaluation of your current state. As for what style..."
Lilo retorted: "I don't play games, but I know that the interactive interface of the game is the most humane. Now, whether it is industrial or military, the human-computer interaction interface is moving closer to the game, and those complex things are thrown to the intelligence for processing."
"Didn't the remote control system you installed on the power armor also use games to modify it? Database the information of your nerves and body, and then present it in a simple and easy-to-understand way. What's wrong with this?"
"Okay, Grandma Lord God," Lilo said so well, and Xia Ming was speechless.
Lilo tilted his head and thought for a while, but didn't understand what the main god and the old lady added together, so he threw it away and ignored it: "Do you want to start testing? Remind that you have to suffer some hardship in order to get the limit of the test."
Looking at the patch electrodes all over his body and the needle tubes inserted into his muscles and blood vessels, Xia Ming sighed: "You have to be gentle."
"No one else except me, no one comes to care about you even if you screamed," Liluo smiled and said, "Whatever you want."
Uh, Xia Ming felt a little dangerous...
After Lilo pointed his finger in the air, the well-sounding ward was drowned by waves of terrifying sounds. The nurses and doctors who occasionally passed by outside the door heard the shrill cry of Youyuan, as if a demon was howling in hell. They subconsciously shivered and hurried away with their heads.
Ten minutes later, Xia Ming's face turned red like a drunk shrimp. He was obviously sweating rising slowly, and the bed sheets under him were all wet.
"How am I calling?"
"It's very penetrating, and the rhythm is also good. It just rightly vents pain."
"Thank you, please rate it."
"I'll give you 9 points. One point is because I'm afraid you're proud."
"I mean this model of yours!"
The kung fu with Liluo was also rated in his vision.
"Strong, 28 (Your nerves are thicker than elephants, are you still human?)"
"Response, 2.5 (Your nerve reaction is 2.5 times faster than ordinary people on average! Generally speaking, the stronger the nerve, the slower the reflex speed, and your existence is anti-scientific!)"
"Sensitivity, 22 (Your nerves are sensitive and you can detect a mite crawling on your body. If it is not related to consciousness, then you will be too unfortunate."
"Physical constitution, 0.7 (your muscle strength, bone density, and cardiopulmonary ability are only 70% of that of adult men. You are either suffering from injuries or a dead house."
"Dexterity, 0.6, (Whether it is the movement envelope of your joints and muscles, or the tolerance of ligaments and other soft tissues, it only reaches 60% of the standard adult males. You are so clumsy that you can't handle even a junior high school student.)"
"Endurance, 4.2, (your body's tolerance for fatigue and pain exceeds that of the saints!)"
"Status, dangerous, (Your condition is obviously abnormal now, your body is too weak and your nerves are too strong, you are like a guy who has just traveled through the body to take over.)"
Xia Ming checked this "attribute report" and asked Xia Xiaoyan first: "Aren't you complaining about the words in the brackets?"
Xia Xiaoyan's 2D small avatar shook cutely: "No, but if you like it, I will take the initiative to add it in the future."
"veto!"
Xia Ming dispelled her intention and asked Liluo again: "Are you reading online novels recently? I really thought there was an extra system gold finger."
"I have not read the system text that has been outdated for many years." Liluo confessed, which made Xia Ming sigh that China's online culture is profound and has already influenced foreign friends.
"The panel just gives you an intuitive understanding of your body and nerve condition. This model currently only involves the cerebellum and autonomic nerves, not the brain. After all, it is too complex and so sophisticated, and I dare not take action on that part."
"Now the model only has some templates for muscle and skeletal movements. You can edit specific functions in the functional areas defined by these templates. The next stage is to link the detection and management of all your organs."
