(PS: In advance, rocket fuel is not gasoline, rocket fuel is not gasoline, rocket fuel is not gasoline, rocket fuel is not gasoline, I will say important things three times, I will not let everyone continue to complain about me at this point~~Lala~~)

Confidentiality and efficiency are the main reasons why Liu Qingquan came up with quantum communication technology. Of course, in addition to these two, other electromagnetic wave communication technologies have all the advantages, and their impact on the environment and biology can be almost ignored.

When flying cars are flying at high speed, traditional electromagnetic wave communication technology cannot solve the needs of navigation communication positioning well, while quantum communication technology can solve it perfectly.

Quantum communication technology is still in the state of theory and laboratory on the earth, and is still far from being popularized and practical. The technology developed by Liu Qingquan comes from seed space. In Alpha's early scientific research, various quantum-related technologies have been clearly studied.

Now it is equivalent to giving Zhou Jingbo and the others a book to learn. Just experiment according to the contents of the book and manufacture relevant equipment. This will greatly shorten the research time. I believe that it will take not too long to study mature quantum communication technology for installation on flying cars.

"Mingbo, I have some information about quantum communication technology here. You can use it for research and come up with mature technology as soon as possible. We will quote it to flying cars." Liu Qingquan handed it to Zhou Jingbo with an USB flash drive.

"Boss, there is something good again, quantum communication technology, haha, my graduate supervisor is also studying this, now, maybe I can surpass him." Zhou Jingbo was not surprised that Liu Qingquan came up with quantum communication technology. He could even take out the method of practicing the universe's Yuanli, so what's so strange about it?

Everyone has doubts in private, but when you ask Liu Qingquan about technology, he can discuss it with you clearly, completely as if he had developed it himself. In addition, Liu Qingquan himself is very legendary, so no one has too much doubt.

"Don't be too happy, I'll give you the information. If you can't come up with mature technical products as soon as possible, let's see how I deal with you." Liu Qingquan said jokingly. Liu Qingquan has always been a hot topic for these researchers, and everyone has a better time to play.

"Boss, please tell me about time, otherwise I don't have the motivation, so it's better to give me a lottery ticket." Zhou Jingbo obviously knew Liu Qingquan's temper very well, and he made a bet with a smile.

"How is it like a month? I'll give it to the promotion section," Liu Qingquan said with a smile.

"The deal was completed, and the people in my group were invited to have a week's supper~ from Mrs. Li's house." Zhou Jingbo agreed readily.

“Okay~~”

"Everyone heard it. The boss wants to treat us to a midnight snack for a week, but it is from Mrs. Li's house. Are we going to have this midnight snack?" Zhou Jingbo said happily to his teammates next to him.

"I'm sure to eat~~hahaha." The team members naturally started to make a fuss, as if they had already eaten their mouths.

Liu Qingquan shook his head, left here with a smile, and came to his Aerospace Research Institute, preparing to continue to study anti-gravity rockets in a deliberate manner.

Because it is led by Liu Qingquan, the entire Rocket Research Team is currently the largest research team in the research institute. There are more than a dozen research laboratories alone, dozens of research teams, more than a hundred people participating in the research, and the number of personnel is constantly increasing.

Traditional rocket structures generally consist of a head, a head fairing, an oxidant storage box, a fuel (combustion agent) storage box, an instrument compartment, a stage section, an engine thrust structure, a tail compartment and other parts. The parts that need to be separated have a separation connection device.

Liu Qingquan split the research topics that need to be involved in the rocket, designed a research laboratory, a laboratory for researching fuel and catalysts, an engine research laboratory, an instrument satellite research laboratory, and more than a dozen laboratories.

The laboratory then splits its own research topics. For example, the overall design research laboratory divides its own research topics into multiple groups such as the balanced design group, structural design group, dynamic flight design group, etc. for separate research.

Liu Qingquan himself led the team to study the references of key anti-gravity engine technology in the Rockets, because traditional rocket technology has no precedent for using anti-gravity flight technology, and everything needs to be started from scratch in this regard. Fortunately, he has seed space and when encountering difficulties, he can check Alpha's technical information and find solutions.

Traditional rockets or missiles generally adopt multi-stage propulsion structures, that is, most rockets are multi-stage rockets.

Multi-stage rockets are carriers composed of several stages of rockets. Each stage is equipped with engines and fuel, with the purpose of improving the continuous flight capability and final speed of the rocket. Starting from the first stage of the tail, each stage of rocket will automatically fall off after the fuel is used up. At the same time, the next stage of rocket engine begins to work, so that the aircraft continues to accelerate and advance.

Multi-stage rockets can be in series, parallel or series-parallel, but the commonly used forms are in series and in series. Series means connecting multiple rockets into a series through interstage connection/separation mechanisms. The first sub-stage works first, and after the work is completed, it is discarded through the connection/separation mechanism. Then, the upper stage rockets work in sequence and are discarded in sequence until the payload enters the flight orbit; parallel means connecting multiple rockets side by side, and the surrounding sub-stage rockets work first, and after the work is completed, they are discarded in sequence until the payload enters the flight orbit, and the core-stage rocket in the center finally works. Multi-stage rockets connected in this way are also called bundled rockets; if the core-stage rocket itself is a series-connected multi-stage rocket, this form is serial-segmented.

Multi-stage rockets can throw away unnecessary mass, so they can obtain good acceleration performance during rocket flight and gradually reach the predetermined flight speed. At the same time, because engines at each stage work independently, engines can be designed according to the flight conditions of each stage to make the engine in the best working state, thus improving the rocket's flight performance; multi-stage rockets can flexibly select the thrust and working time of each stage to meet the requirements of launching orbits, orbit measurement requirements, and the requirements of manned spacecraft for flight overload.

Of course, multi-stage rockets also have their corresponding disadvantages, with complex structural design and numerous engines; interstage segments need to be added to connect between stages, and many separation times; the structure is slender and has poor bending stiffness, making it difficult to achieve aerodynamic stability; these reasons reduce the reliability of multi-stage rockets and increase their costs accordingly.

Multi-stage rockets are the most mainstream rocket and missile technology today, and are also the most mature technology, and are widely used in the aerospace and military missile fields.

Even Spacex Technology, the most powerful Spacex technology company in the United States, claims to be recycling rockets, actually references multi-stage rocket technology. Its rocket retains the first-stage rocket when it returns to the ground during its launch. When it is recycled, it first relies on the earth's gravity to absorb the atmosphere. When it reaches a certain height, the last-stage rocket begins to ignite and attack, and propels the rocket to a predetermined location for landing, realizing recovery.

Liu Qingquan, who has anti-gravity technology, naturally cannot fully adopt this rocket technology. According to Liu Qingquan's design, rockets equipped with anti-gravity engines should adopt an integrated structure, with only one stage, and no objects need to fall off during the launch process.

Most of the designs of multi-stage rockets are designed to get rid of gravity, one step after another. The entire rocket is very long. When it is erected, it usually has a height of more than 45 meters to more than 50 meters, and it is as high as dozens of floors. However, the one that really needs to be used in space is actually the top instrument compartment, which is only a few meters high.

Using anti-gravity technology, there are no rockets with so many stages to work on getting rid of gravity. Moreover, relying on anti-gravity technology, the entire rocket launch process should be more fuel-saving than traditional rockets.

The structure and design of the Rockets are relatively much simpler. For example, the design of the interval between the Rockets stages can be completely abandoned, the overall design reliability will be very stable and the cost will be much lower.

Multi-stage rockets are generally composed of first-stage, second-stage, third-stage or even N-stage rockets. The bottom rockets are actually the same mechanism. They are composed of fuel tanks and oxidant tanks, and are connected to each other in segments. The lower rockets will automatically fall off after completing their work. The superior rockets will ignite and then advance, one after another.

At the top of the rocket, it is the instrument cabin, satellite or spacecraft launch bracket, satellite or spacecraft, fairing, and these things are the most precious things for the rocket and are also the purpose of the work of the N-class rocket below.

Compared with traditional rockets, the design of the anti-gravity rocket is much simpler. The N-class propelling rocket is just one stage left, and the head design is the same.

A simple design can greatly improve the stability and reliability of the rocket, and at the same time, the environment required for rocket launch is also greatly reduced, because there are no falling parts, and there will be no accidental casualties and losses caused by falling parts.

Liu Qingquan carefully listened to the latest reports on the laboratories, and at the same time, he kept writing down the problems they encountered with his pen. When he encountered something he could solve immediately, he would tell the other party about his thoughts and considerations. It was really a big problem, so he needed to look for someone to study together. If he couldn't find any research, he could only go to the seed space to find corresponding technical materials to solve it.

"Boss, this is the structural diagram of the overall structural design group design. Please give me some advice." A researcher handed over a rocket design drawing.

"Well~ I'll take a look first." Liu Qingquan took the drawing and looked slowly. Liu Qingquan, who works, is also very serious. Careful people, especially those who are skilled, cannot be careless at all, because often it is because of a slight negligence or carelessness that will cause major disasters.

Just like on January 28, 1986: The US Challenger space shuttle exploded 72 seconds after it took off from Cape Canaveral, seven American Space Warriors, including a teacher, died. The cause of the crash was that the O-type sealing ring at the bottom of the solid fuel tank was cold and the sealing effect was reduced.

In this regard, Qingquan Technology's research institute has always had very strict requirements and management. Everything must be serious and serious, carefully and carefully, and there must be no careless!
