Dahan Technology Empire

(PS: Let me explain in advance that rocket fuel is not gasoline, rocket fuel is not gasoline, rocket fuel is not gasoline, and important things are said three times, I will not let everyone continue to complain about me on this point~~ la la~~)

Confidentiality and high efficiency are the main reasons for Liu Qingquan to come up with quantum communication technology. Of course, apart from these two, other electromagnetic wave communication technologies have all the advantages, and the impact on the environment and biology is almost negligible.

In the high-speed flight of flying cars, traditional electromagnetic wave communication technology cannot well solve the needs of navigation, communication and positioning, while quantum communication technology can perfectly solve it.

Quantum communication technology is still in a theoretical and laboratory state on Earth, and there is still a long way to go before it is popularized and practical. The technology that Liu Qingquan came up with came from the seed space. In the early scientific research of the Alpha people, quantum communication technology has long been used. A variety of related technical research is clear.

Now it is equivalent to giving Zhou Jingbo and the others a book and asking them to learn, as long as they experiment according to the contents of the book and manufacture relevant equipment, which can greatly shorten the research time. I believe it will not take too long to develop a mature Quantum communication technology for installation on flying cars.

Jingbo, I have some information about quantum communication technology here. You can take it for research and come up with mature technology as soon as possible. We will quote it on the flying car. Liu Qingquan handed a USB flash drive to Zhou Jingbo.

Boss, there is another good thing, quantum communication technology, haha, my graduate tutor is also studying this, now, maybe I can surpass him. Zhou Jingbo was not surprised that Liu Qingquan came up with quantum communication technology. You can take out all the cultivation methods of the universe's Yuan force, and what else is strange.

In fact, everyone has doubts in private, but about technology, if you ask Liu Qingquan, he can discuss it with you clearly. , and everyone has no doubts.

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, let's see how I clean up you. Liu Qingquan said jokingly, Liu Qingquan has always been fiery towards these researchers. Everyone played better.

Boss, please tell me the time, otherwise I'm out of motivation, it's better to give some more money. Zhou Jingbo obviously knew Liu Qingquan's temper very well, and he made a bet with a smile.

How about a month? I'll give it a higher rank when I figure it out, Liu Qingquan said with a smile.

Deal, plus invite my group to have a week's supper~ from Mrs. Li's house Zhou Jingbo readily agreed.

Okay~~

Everyone has heard it, the boss wants to invite us to dinner for a week, or it's from Sister-in-law Li's house. Are we ready for this supper? Zhou Jingbo said happily to the teammates next to him.

It's ready~~ Hahaha The team members naturally booed, as if all of them had 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 institute. There are more than ten research laboratories alone, dozens of research groups, and more than one hundred people participating in the research. The manpower is still increasing.

The traditional rocket structure is generally composed of the head, the head fairing, the oxidant storage tank and the fuel (burning agent) storage tank, the instrument cabin, the interstage, the engine thrust structure, the tail cabin, etc. The parts that need to be separated have a separation connection device .

And Liu Qingquan divided the research topics that need to be involved in the rocket. There are more than ten laboratories such as the overall design research laboratory, the laboratory for fuel and catalyst research, the engine research laboratory, and the instrument satellite research laboratory.

The laboratory then splits its own research topics,

For example, the overall design research laboratory has split into multiple groups such as the balance design group, the structural design group, and the dynamic flight design group for their own research topics, and conduct separate research.

And Liu Qingquan himself led the team to study the use of the key anti-gravity launch technology in rockets, because there is no precedent for the use of anti-gravity flight technology in traditional rocket technology. There is a seed space, and when you encounter a problem, you can go to the technical information of the Alpha people to 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 delivery vehicle composed of several stages of 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, each stage will automatically fall off after the rocket fuel is used up, and at the same time, the next stage rocket engine will start to work, so that the The aircraft continued to accelerate forward.

Multistage 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 string through the inter-stage connection/separation mechanism. The first sub-stage is at the bottom and works first. After the work is completed, it is discarded through the connection/separation mechanism. Then, the upper stage rockets work in turn and are Abandon in turn 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 then are abandoned in turn until the payload enters the flight orbit, and the central core-stage rocket lasts. Work. Multistage rockets connected in this way are also called bundled rockets; if the core stage rocket itself is a series multistage rocket, this form is a series-parallel rocket.

Multi-stage rockets can throw away unnecessary mass, so during the flight of the rocket, good acceleration performance can be obtained, and the predetermined flight speed can be gradually reached; at the same time, because the engines at all levels work independently, they can be operated according to the flight conditions of each stage. Design the engine so that the engine is in the best working condition, thereby improving the flight performance of the rocket; the multi-stage rocket can flexibly choose the thrust size and working time of each stage to meet the requirements of the launch orbit, orbit measurement requirements and load. The requirements of human spacecraft for flight overload.

Of course, multi-stage rockets also have their corresponding shortcomings. The structure design is complex and the number of engines is large; the inter-stage connection between stages is required to be connected, and the number of separations is large; the structure is slender and the bending stiffness is poor, and it is not easy to achieve aerodynamic stability; these The reasons are to reduce the reliability of the multi-stage rocket and correspondingly increase its cost.

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 most famous SpaceX technology company in the United States, although it claims to be a recycling rocket, actually refers to multi-stage rocket technology. Its rocket retains the first-stage rocket during the launch process to return to the ground. The recovered rocket is used. At that time, it first relies on the gravity of the earth to be sucked into the atmosphere, and when it reaches a certain height, the last stage of the rocket starts to ignite and attack, and the propelling rocket reaches the predetermined location for landing and recovery.

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

Most of the multi-stage rockets are designed to get rid of gravity, and the design is one stage after another. The entire rocket is very long. When it is erected, the height is generally 45 meters to more than 50 meters, and it is as high as dozens of floors; however, What really needs to be used in space is actually the uppermost instrument warehouse, which is only a few meters high.

With anti-gravity technology, there are absolutely no rockets with so many stages 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 much simpler. For example, the design of the space between the stages of the rocket can be completely discarded, 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-stage, second-stage, third-stage or even N-stage rockets. The bottom rocket actually has the same mechanism, consisting of a fuel tank and an oxidizer tank, which are linked with each other by inter-sections, and the lower-stage rocket will automatically complete its work. Falling off, the upper stage rocket ignites and then pushes forward, one stage after another.

At the top of the rocket is the instrument cabin, satellite or spacecraft launch bracket, satellite or spacecraft, and fairing. These things are the most valuable of the rocket, and they are also the purpose of the N-stage rocket below.

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

The simple design can greatly improve the stability and reliability of the rocket, and at the same time, the environment required for the rocket launch is also greatly reduced, because there are no parts that fall off, and there will be no accidental casualties and losses due to falling parts.

Liu Qingquan listened carefully to the latest reports from each laboratory, and kept writing down the problems they encountered with a pen. When he encountered something that he could solve immediately, he would tell the other party his thoughts and considerations. It was really great. If there is a problem, you need to go back and find someone to study it together. If the study fails, you can only go to the seed space to find the corresponding technical information to solve it.

Boss, this is the structure diagram designed by the overall structure design team. You can take a look and give some opinions. A researcher handed over a rocket design drawing.

Yeah~ I'll take a look first. Liu Qingquan took over the drawing and looked at it slowly. Liu Qingquan, who worked, was also a very serious and careful person, especially a technical person. He should not be sloppy at all, because many times Just because a little negligence or sloppy can cause a major disaster.

Like January 28, 1986: The space shuttle Challenger exploded 72 seconds after liftoff from Cape Canaveral, killing seven astronauts, including a teacher. The cause of the crash was actually caused by the cold shrinkage of the O-ring seal at the bottom of the solid fuel tank due to the low temperature, which reduced the sealing effect.

In this regard, the research institute of Qingquan Technology has always had very strict requirements and management.
