Confidentiality and efficiency are the main reasons for Liu Qingquan to come up with quantum communication technology. Of course, in addition to these two, other electromagnetic wave communication technology has all the advantages, it also has all, and the impact on the environment and biology can be ignored.
In the high-speed flight of flying cars, the traditional electromagnetic wave communication technology can't well solve the needs of navigation communication positioning, and quantum communication technology can solve it perfectly.
Quantum communication technology is still in the state of theory and laboratory on the earth, and there is still a long way to go before it can be used. Liu Qingquan's technology comes from the seed space. In the early scientific research of the Alpha, the quantum Relevant research on various technologies is clear.
Now it is equivalent to giving Zhou Jingbo a book for them to learn, as long as they experiment with the content of the book and make related equipment, this can greatly shorten the research time. I believe that it will take a long time to mature. Quantum communication technology for mounting on flying cars.
"Mirror wave, I have some information about quantum communication technology here. You can research it, and come up with mature technology as soon as possible. We will quote it to the flying car." Liu Qingquan held a USB flash drive and passed it to Zhou Jingbo.
"Boss, there are good things. Quantum communication technology. Haha, my graduate tutor is also studying this. Now, maybe I can surpass him." For Liu Qingquan's quantum communication technology, Zhou Jingbo was not surprised at all, even Cosmic elemental strength cultivation methods can be taken out, what else is strange.
Everyone actually had suspicions in private, but regarding technical issues, you can ask Liu Qingquan and he can discuss clearly with you. It is exactly what he researched, plus Liu Qingquan is very legendary. No one doubts too much.
"Don't be too happy, the information is given to you. If you can't come up with mature technical products as soon as possible, and see how I can pack you," Liu Qingquan jokingly said, for these researchers, Liu Qingquan has always been fiery, Everyone plays better.
"Boss, let me tell you the time, otherwise I have no motivation, it is best to give a little bit more glory." Zhou Jingbo is obviously also very clear about Liu Qingquan's temper, and raised the bet with a smile.
"How about a month? I'll give you a boost when I get it out," Liu Qingquan said with a smile.
"The transaction, plus someone from my group to have a supper for a week ~ Li Dazhen's house" Zhou Jingbo agreed quickly.
"Okay ~~"
"The big guys heard it. The boss wants to invite us to have a supper for a week, or it's Li Dayi's family. Will we have a supper for this supper?" Zhou Jingbo said happily to the teammate next to him.
The members of the group "have settled ~~ hahaha" are naturally coquettish, one by one seems to have eaten their mouths.
Liu Qingquan shook his head, left here with a smile, and came to his own aerospace research institute, ready to continue to study anti-gravity rockets.
Because Liu Qingquan led the team, the entire rocket research team is currently the largest research team in the academy. There are more than ten research laboratories alone, dozens of research groups, and more than one hundred people participating in research. Manpower is constantly increasing.
The traditional rocket structure is generally composed of the head, the cowl, the oxidant storage tank and the fuel (burning agent) storage tank, the instrument compartment, the interstage section, the engine thrust structure, and the tail tank. .
And Liu Qingquan split the research topics that need to be involved in the rocket, including the overall design of a research laboratory, a research laboratory for fuels and catalysts, an engine research laboratory, an instrument satellite research laboratory, and so on.
The laboratory then splits its own research topics. Like the overall design research laboratory, it splits its research topics into balanced design groups, structural design groups, dynamic flight design groups, and other groups for separate research.
And Liu Qingquan himself led the team to study the key anti-gravity launch technology in the rocket, because the traditional rocket technology has no precedent for the use of anti-gravity flight technology. In this regard, everything needs to be started from scratch. Fortunately, he There is a seed space. When you encounter a problem, you can consult the technical information of the Alpha person and find a solution.
Traditional rockets or missiles generally use multi-stage propulsion structures, that is, most rockets are multi-stage rockets.
A multi-stage rocket is a launch vehicle composed of several rockets. Each stage is equipped with an engine and fuel. The purpose is to improve the continuous flight capability and final speed of the rocket. Starting from the first stage of the tail, the rocket will automatically fall off after each stage of fuel is exhausted, and the next stage rocket engine will start to work, so that The aircraft continued to accelerate.
Multi-stage rockets can be series, parallel, or series-parallel, but the common forms are series and series-parallel. Tandem is to connect multiple rockets into a series through the interstage connection / disconnection mechanism. The first sub-stage is at the bottom and works first. After the work is completed, it is discarded by the connection / disconnection mechanism. Then, its upper stage rockets work in turn and are Discard them in sequence until the payload enters the flight orbit; parallel connection is to connect multiple rockets side by side. The surrounding sub-stage rockets work first and are discarded in turn until the payload enters the flight orbit. jobs. Multi-stage rockets connected in this way are also called bundled rockets; if the core-stage rocket itself is a serial multi-stage rocket, this form is series-parallel.
Multi-stage rockets can throw away unwanted mass, so during the flight of the rocket, it can obtain good acceleration performance and gradually reach the predetermined flight speed; at the same time, because the engines of each level work independently, they can be operated according to the flight conditions of each level. Design the engine so that the engine is in the best working condition, which also improves the flight performance of the rocket; the multi-stage rocket can flexibly select the thrust and the working time of each stage to meet the requirements of the launch orbit, the orbit measurement requirements and the load Human spacecraft's requirements for flight overload.
Of course, the multi-stage rocket also has its corresponding disadvantages. The structure design is complex and the number of engines is large. The inter-stages need to be connected between the stages and the number of separations is large. The structure is slender and the bending stiffness is poor, which makes it difficult to achieve aerodynamic stability. The reason is to reduce the reliability of the multi-stage rocket and increase its cost accordingly.
Multi-stage rocket is the most mainstream rocket and missile technology today, and it is also the most mature technology. It is widely used in the field of aerospace and military missiles.
Even the best American space technology company, although it claims to be a recovery rocket, actually uses multi-stage rocket technology. Its rocket retains a first-level rocket for return to the ground during the launch process, and when it is recycled. First, it relied on the gravity of the earth to into the atmosphere. When the altitude reached a certain level, the last stage of the rocket began to ignite and attack, propelling the rocket to a predetermined location for landing, and achieving recovery.
Naturally, Liu Qingquan, who has anti-gravity technology, cannot fully use this rocket technology. According to Liu Qingquan's design, a rocket equipped with an anti-gravity engine should adopt an integrated structure, only one level, and there is no object during the launch process. Need to fall off.
Most of the design of multi-stage rockets are designed to get rid of gravity, and the design is one level after another. The entire rocket is very long. When it is erected, it usually has a height of 45 to 50 meters, as high as dozens of floors. However, What really needs to be used in space is actually the top instrument warehouse, which is only a few meters high.
With anti-gravity technology, there are not so many stages of rockets to work to get rid of gravity, and relying on anti-gravity technology, the entire rocket launch process should be more fuel efficient than traditional rockets.
The structure and design of the rocket are relatively simple and much simpler. The design of the interval between the rocket stage and the stage can be completely abandoned, and the reliability of the overall design will be very stable, and the cost will be much lower.
Multi-stage rockets are generally composed of first-, second-, third-, and even n-stage rockets. The bottom rockets are actually the same. They are composed of fuel tanks and oxidant tanks. Fall off, the superior rocket ignites and then advances, level by level.
At the top of the rocket is the instrument bay, satellite or spacecraft launching bracket, satellite or spaceship, fairing. These things are the most valuable of the rocket, and it is also the purpose of the n-stage rocket to do work.
Compared to traditional rockets, the design of anti-gravity rockets is much simpler. The n-stage propulsion rocket can be left with only one stage, and the head design can be the same.
The simple design can greatly improve the stability and reliability of the rocket. At the same time, the environment required for the rocket launch is also greatly reduced, because there are no falling parts, and accidental injuries and losses will not be caused by the falling parts.
Liu Qingquan listened carefully to the latest reports from the various laboratories, and kept writing down the problems they encountered. When he encountered what he could solve immediately, he told his thoughts and considerations to the other party. It was very big. If you ca n’t do research, you can only go to the seed space to find the corresponding technical information to solve the problem.
"Boss, this is the structural diagram designed by the overall structural design team. Please show it and give some comments." A researcher handed a rocket design drawing.
"Well, let me take a look." Liu Qingquan took the drawing and slowly looked up. Liu Qingquan who worked was also a very serious and careful person, especially a person who engaged in technology. It is because of a little negligence or carelessness that it will cause a major disaster.
Just like January 28, 1986: The American Challenger space shuttle exploded 72 seconds from Cape Canaveral and seven American space warriors, including a teacher, were killed. The cause of the accident turned out to be that the low temperature caused the o-ring seal at the bottom of the solid fuel tank to shrink and reduce the sealing effect.
In this regard, the research institute of Qingquan Technology always has very strict requirements and management. All things must be taken seriously, carefully and carefully, and there must be no sloppy place!
