When the third child heard this, his face turned red and he nodded in agreement.
The little goldfish and the others cheered and joked with smiles, but the third child waved their hands in disgust, telling them to shut up.
Seeing them laughing and having fun, Zhou Jimin said again:
"It's like this. I'm going back to the capital in the afternoon and will come back in two days. You guys, the third and fourth, will watch them these two days..."
"Okay, brother, don't worry."
It’s not the first time anyway, so Zhou Jimin is of course relieved.
In the afternoon, Zhou Jimin left the small town of *** and stayed in the capital for two days.
The current situation of the little fat pig has improved slightly, but it is limited.
At just over a year old, he still needs help to walk. He is slightly trembling and stumbling, making him much worse than his older brothers and sisters.
Zhou Jimin checked the little guy as usual and confirmed that there was nothing wrong with his body, which made him feel relieved.
This child is what he and Ding Qiunan worry about the most, and they have put a lot of effort into it.
But he is like a man who understands nine of his ten orifices. He knows nothing, whether it's talking or walking. It's really heartbreaking.
"After he turns two years old, I will feed him space spring water to see if there will be any improvement by then."
Thinking silently in his heart, Zhou Jimin put the matter aside.
He has many children, and his expectation for them is that they grow up healthy and happy.
Regardless of whether it is the child born by Ding Qiunan or the child born by Qin Jingru and the others, he treats them equally.
Only the little fat pig has really worried him from birth to now.
It is said that one looks eighty at the age of three. As far as the current situation of the little fat pig is concerned, if it does not return to normal before the age of three, Zhou Jimin will really be in a hurry.
Among infants and young children born all over the world, there are always some children who are infected with some strange diseases.
Although the little fat pig looks very healthy, from the current point of view, he should have some so-called hidden diseases.
Alas!
After staying in the capital for two days, Zhou Jimin returned to the small town of *** and continued his recklessness.
The engine is still in the wind tunnel laboratory, and there is currently no way to conduct further research, so let’s tinker with the missile propulsion system.
This time, he did not use new materials.
Baiyi alloy material is too expensive, and he doesn't dare to use it on missiles.
Besides, it may not be appropriate.
Intercontinental missiles, also known as ballistic missiles, usually consist of a propulsion system, a warhead, a missile body structure and a guidance system.
At present, there are no other types of intercontinental missiles. There is only one type, and that is the land-based intercontinental missile.
The research and development of land-based intercontinental missile propulsion systems has actually involved rocket launch thrusters.
After all, the fastest speed of future intercontinental missiles is Mach 27.
At present, the fastest speeds of the intercontinental missiles of the two countries, Polar Bear and Bald Eagle, exceed Mach 20.
However, in fact, it is useless to be fast because it is too restrictive.
Moreover, the precision strike error is very large, usually around 2.5 kilometers to 5 kilometers, which is a huge deviation.
Of course, even if the deviation is large, the nuclear warhead of an intercontinental missile is quite powerful.
Due to the reference materials, when Zhou Jimin participated in this project, he proposed that the power of missiles should not be improved simply by relying on large yields, but that precision strike, maneuverability, miniaturization and other aspects should be considered for research and development.
Especially for the guidance system, advanced technologies such as starlight guidance and radar guidance should be developed, and a fast-burning engine can be developed to enable the missile to automatically shut down and fly at an altitude of 80 kilometers.
Spray anti-laser materials or other protective materials on the surface of the missile to improve its own protection capabilities, etc.
These ideas he put forward were unanimously praised by experts from the entire project team.
After all, precision strike and maneuverability are what are most needed on the battlefield.
If the current land-based missiles of Polar Bear and Bald Eagle are discovered by satellites, then an intercontinental missile will pass by and the entire missile launch base will be useless.
However, vehicle-mounted intercontinental missiles with ultra-high maneuverability are not afraid of these at all. Coupled with precision strike capabilities, this is the enemy's nightmare.
Since the establishment of the project, the overall project progress has been quite fast.
The town of Liuer is also involved. After all, the guidance system still requires their participation.
Zhou Jimin is responsible for the fast-burning engines and other missile propulsion systems in the propulsion system.
At present, it can be said that there is no progress at all on Zhou Jimin's side.
He put the fast-burning engine last. What he needs to deal with now is the rocket engine.
The rocket and satellite developed by *** Xiaocheng can only reach Mach 17 in speed. They are just copied and improved. It is useless as a missile propulsion system.
First, rockets and satellites are still too big, and their launch and take-off propulsion weights are in the 100-ton level.
The weight of vehicle-mounted missiles is generally less than 100 tons, and more often 40 or 50 tons.
In other words, its propulsion system will be more advanced, the speed will be faster, and the fuel used for propulsion will be lighter.
The propulsion system can't already weigh 70 or 80 tons, leaving the other warheads with only 20 tons in weight for the missile structure and guidance system, right?
Even so, such a missile is quite bloated, and the requirements for a mobile vehicle carrying the missile will be very high.
After all, generally speaking, the load capacity of large trucks is about ten tons. If a super-heavy truck transporting 100 tons is transported, the fuel consumption per kilometer will be very alarming.
As for vehicle-mounted missiles, maneuverability is more important, so while ensuring the power of the missile, try to reduce the weight of the missile itself. Only in this way can its maneuverability be guaranteed.
A few days later, the wind tunnel laboratory was completed and Zhou Jimin began to inspect the engine.
The improved high-speed ramjet engine made of new Baiyi alloy materials has no problems at all.
The testing in the indoor wind tunnel laboratory has been completed, and the next step is the outdoor wind tunnel laboratory.
All steps must be carried out strictly according to the plan, and no step can be missed.
This chapter is not over yet, please click on the next page to continue reading!
Zhou Jimin still cherishes his life. Although he has space, it is almost difficult to encounter danger.
But who knows?
Things like rebirth have happened, how can he guarantee that no accident will happen?
His life is his own, not someone else's.
"Dad, is there anything happy that happened? Do you want to share it with us?"
While the laboratory was conducting tests, Zhou Jimin walked out of the study and went outside to relax.
During the recent period, except for the two days he spent in the capital, the rest of the time he was in constant motion, almost never stopping.
I finally went for a walk today. The children happened to be playing in the yard on the weekend.
When they saw their father strolling around with a smile, they all came over and surrounded him.
"Well, Dad did encounter something happy, because Dad solved a big problem..."
The little kids didn't ask any questions, just chattering and pulling him to play games together.
Compared to the capital, there are many more games they can play here in the small town.
Especially those toys at home, every time they invite their friends to play at home, they always get the exclamations from their friends.
In exchange for these toys, they have some foreign friends who invite them to play some games that they know how to play.
There are many different ways to play, such as singing children's songs, playing counting games, card games, catching singles and not catching evens, etc.
After playing with the little kids for more than an hour, Zhou Jimin left home and went to the satellite communications office.
"Xiao Yan, isn't Lao Zeng here?"
Here in the Communications Department, Yan Ziyue was busy with his head down. When he heard the sound of ticking coming from the door, he didn't even look up.
It wasn't until Zhou Jimin's voice sounded that he saw it was Zhou Jimin.
"Hello, Boss Panda, it's like this. Director Zeng is at the research institute, not here."
Yan Ziyue quickly stood up and said respectfully.
"It's okay, is Lao Dong in there?"
"Yes, Team Leader Dong is in the office inside."
"Okay, you go ahead and do your work, I can just go there by myself."
Zhou Jimin nodded and said nothing more to the other party.
After all, his identity is different. An ordinary researcher like Yan Ziyue will still be somewhat nervous when facing him.
Coming to the office inside, Zhou Jimin briefed Dong Chuanan.
The latter is the project team leader of the Satellite Communications Division, and is one of the leaders of the entire Communications Division, except for Zeng Qingfeng and a few others.
Naturally, I came to see this person today not to chat, but to ask about the satellite communication system.
According to Dong Chuanan, the seven satellites in space are currently operating well. From previous tests, they can basically communicate across the country.
However, it is currently difficult to conduct testing in other parts of the world, so it is basically limited to the mainland.
"No problem, I will go to different places next time to assist you in testing. By the way, there should be no problem at the North and South Poles, right?"
Dong Chuanan was stunned for a moment when he heard this, and then shook his head, "Theoretically speaking, there is no problem with communication between the two poles, but the signal may not be that strong..."
You know, the north and south poles are the places where the earth’s magnetic field interferes the most.
Therefore, even with satellite communications, it is not that easy to achieve communication between the North and South Poles.
Of course, there is no need to go to the North and South Pole to conduct scientific research activities now, so it doesn’t matter whether you can talk on the phone.
After the satellite communication problem is solved, the next step is the navigation system.
As we all know, satellite navigation and positioning systems require at least four satellites to determine the user's three-dimensional location information, namely longitude, latitude and altitude.
In other words, the navigation system has actually been solved.
The navigation and communication can share one satellite, and there is no need to launch additional satellites.
Of course, if you want to obtain more accurate navigation information, just four satellites are not enough.
At least forty-five are needed, just like the Beidou navigation system.
However, in today's small town, there is money but no one, and many materials are not so easy to obtain.
Therefore, if you want to launch the next satellite quickly, please wait slowly.
After getting to know each other, Zhou Jimin left.
Then he went to the Aircraft Research Institute and stayed with Xu Lei and the others for a long time before going home for dinner.
Not to mention, the current aircraft research institute has become more and more standardized, and its innovation capabilities are getting stronger and stronger.
However, they are still diligently pursuing technologies such as vertical take-off and landing, but Zhou Jimin is still holding on to it.
I dismissed them with just one sentence, my manufacturing ability is too poor.
Every time Xu Lei and the others wanted to ask, what went wrong?
As a result, Zhou Jimin directly asked: Can you create high-temperature-resistant materials that can withstand temperatures of tens of thousands of degrees?
Hiss!
Just such a question stopped them in their tracks.
Obviously, in addition to this high-temperature resistant material, this material must have other thresholds.
It has been more than three years since their aircraft research institute was established, but they are still thinking hard about increasing the speed of the engine from Mach 1.05 to Mach 1.1.
However, Zhou Jimin built a supersonic aircraft early.
The speed of the 65-speed supersonic aircraft is no longer a secret within the Aircraft Research Institute.
Supersonic speed exceeding Mach 3 is shocking and invincible.
Philip really wanted Zhou Jimin to write down the relevant requirements for the materials so that they could find or research such materials.
In this regard, Zhou Jimin said that at present, it is useless for all the materials science experts, chemistry experts, physics and mathematics experts in the small town to get together.
It can’t be taken out!
Why?
Because the material of the 65 supersonic aircraft is Baiyi alloy material that is fused with gray and white metal. Only he has this stuff.
On Earth, the only countries that can currently produce such materials are polar bears and bald eagles.
But it is not possible to build an airplane just by having qualified materials.
Therefore, Zhou Jimin has always emphasized that the manufacturing industry is not good, which is no joke.
How can it be so simple to build a factory that can withstand high temperatures of 10,000 degrees and high temperature-resistant materials?
A factory that has reached this level means that the manufacturing level of the entire industry has reached an extremely high level.
Anyway, for now, it’s very difficult on earth.
Suddenly, Zhou Jimin did not go out, but stayed in the study to tinker with the missile propulsion system.
Miniaturization of the propulsion system means that the missile engine must also become smaller, but the propulsion speed must be faster.
A bit brain-burning!
It’s not just the material that’s limited, it’s the fuel.
After two days of hard work, the four engines have been tested in the outdoor wind tunnel laboratory, and there are currently no problems.
The final step is to assemble it.
At this point, Zhou Jimin also became excited.
After completing the assembly, go to the outdoor wind tunnel laboratory for testing. Once completed, you can soar into the sky.
What an exciting moment.
It took two days outside and ten days in space to complete the assembly. Only then did Zhou Jimin put the aircraft in the outdoor wind tunnel laboratory for testing.
This new type of supersonic aircraft is, first of all, similar in appearance to the 65 aircraft, but it is much smaller and has a more sci-fi feel.
And the tail, wings, etc. have been greatly improved to avoid radar scanning.
As we all know, the working principle of radar is very simple, which is to use the principle of electromagnetic wave coherence to complete the radar's search, tracking and measurement of targets.
In the past, wings and tails were easily tracked by radar electromagnetic waves and fed back signals to the radar receiver.
After the improvement, the radar system is equivalent to being blind, that is, it achieves the purpose of being invisible from the monitoring system.
Secondly, there are only 28 seats, and the location is relatively compact, and there is no lounge at the back.
In other words, the passenger capacity is really only twenty-eight people.
In order to make the aircraft invisible, this aircraft sacrificed many entertainment facilities.
Finally, this aircraft has four engines, which is quite powerful in terms of power.
Let's put it this way, according to the laboratory test speed, the ultimate speed of this aircraft can reach Mach 12.5.
Even if there is only one auxiliary engine flying, the flight speed can easily exceed Mach 3 when the main engine stalls.
This is the awesomeness of these four engines.
Simple superposition can increase the speed dramatically, but in fact, if the aircraft materials, overall system, etc. are not good enough, superposition is impossible.
After all, the flying speed of Mach 12.5 is simply terrifying.
This speed can basically be achieved anywhere in the world in one hour.
However, it is not yet completely certain whether it can reach the same speed as the 65-speed supersonic aircraft.
The process of waiting for the test is very painful.
Zhou Jimin did not continue to stay in the space, but came outside, ran to the medical research institute outside, and started research with others.
Zhang Fei is sitting in a clinic, and he goes to work and gets off work on time every day.
Seeing Zhou Jimin come in, he smiled and nodded in greeting, and then continued the consultation.
Zhang Fei is very grateful to Zhou Jimin.
But it is limited to gratitude. For him, where is work not work?
Not long after, the consultation was over, and Zhang Fei started chatting with Zhou Jimin.
We are all busy people. Although we are in the same small town, it is rare to chat.
Of course, Zhou Jimin was not just chatting, but talking about medical matters.
He had asked Zhang Fei for advice about the little fat pig a long time ago, but after Zhang Fei read it, he said there was nothing he could do.
Because the little fat pig is not sick, or he is not sick at the moment.
Premature birth involves more aspects of medical knowledge and requires a large amount of data to support it.
With the current level of science and technology, it is difficult to publish something.
However, Zhou Jimin came today not to consult about the little fat pig, but simply to ask about some medical knowledge and simply wanted to change his mind.
After chatting for a long time, he returned satisfied.
When he got home, Xiaoxian and the others had finished school, and he took the children to cook together again.
Zhou Qingxian, who is over eight years old, has already learned how to cook.
However, they are not too tall, and the third and fourth children are all here, so naturally Xiaoxian and the others are not the ones doing the cooking.
Zhou Jimin spent the next few days living in such a relaxed and comfortable life.
Philip and the others were so happy that they dragged Zhou Jimin to the Aircraft Research Institute, hoping to get him to help solve some of the current problems.
However, the issue of research and development of aircraft engines, after all, is still a competition between manpower and manufacturing level.
Therefore, it is impossible to rely solely on Zhou Jimin.
Unless Zhou Jimin cheats directly, there is no point in cheating on this matter. The level of manufacturing industry must be comprehensively improved.
A few days later, the aircraft test was finally completed.
