Two days later, Chen Nian ended his trip to the south.
This trip was fruitful for the country, but it was just okay for him.
Because of the technological fission effect, the number of his source points has grown slowly, and he has accumulated 1.02 source points so far. If he encounters suitable technology, he can analyze them first.
However, for now, the key breakthrough point he is waiting for has not yet appeared, and the Spark Working Group has not given further opinions.
Therefore, all he can do is continue to study and further accumulate source points.
He has just started taking the advanced course on silicon materials, and there is still a lot of room for follow-up. It is expected that if he can complete the course, he can obtain at least 4 source points.
In addition, he also plans to slowly start learning about the ship's power system, and first use his spare time to get in touch with the system to establish a rough concept for himself.
After all, this thing is the most critical factor restricting the development of our country's aircraft carriers and large warships. For a long time, it has been a stuck weakness.
If it can be resolved, the Navy will quickly enter the dumpling stage.
Therefore, after returning to NPU, the first thing Chen Nian did was to go to the library to look for information. On the way, he met Li Xiang and chatted with him for a few words, but this guy seemed to be very busy and left in a hurry. Open - It is estimated that the recent UFO incident has greatly increased the workload of the War Ignorance Bureau, and he has to take up the task.
When he arrived at the library, Chen Nian found the basic information he needed.
"Principles of Ships", "New Technologies in Surface Ship Design" and "Principles of Ship Power Plants".
After initially opening it and taking a few glances, Chen Nian couldn't help but feel dizzy.
This thing is really completely different from the spacecraft design that I am mainly engaged in now.
The principles of diesel generators alone are fundamentally different from those of aviation engines.
It is still a bit difficult to cross the past in the short term.
Fortunately, he was not in a hurry and just regarded it as extracurricular reading.
With this in mind, Chen Nian started walking back with the materials, but before he left the school, his attention was suddenly drawn to the activities on the lawn.
It was a gathering of an aircraft model interest group. A large lawn was filled with various model aircraft. Everyone gathered on the grass to communicate and test fly in a lively manner.
Chen Nian walked over curiously and found many acquaintances from the class in the crowd.
Those acquaintances also discovered him, and one of his classmates named Yu Yue ran over to greet him enthusiastically and said:
"Hey, Chen Nian, are you free recently? I heard that you went to participate in an officially organized air show for exchanges. How was it? Is it fun?"
This is the unified message output by the Intelligence Department to Chen Nian. Every time he leaves NPU, there must be an inexplicable exchange outside. Chen Nian only needs to follow the instructions.
"Well, it's not interesting. Anyway, I just went there to have a look and gain some insights."
"That's good! Hey, do you want to come and play? We have all kinds of airplanes. Can you give us some advice?"
Following the direction of his finger, Chen Nian looked around and found that the man was really not bragging.
From old-fashioned propeller aircraft such as the JJ-6, Mosquito, and S4 to the latest F-16, F15, and even B-2, this place is simply like an exhibition of aircraft from all over the world, but in a smaller version.
"Can this all fly?"
Chen Nian asked curiously.
"Well, everyone is doing this with the intention of flying, but it's not necessarily true whether they can actually fly."
"Anyway, that B-2 has been optimized for a year, and it is still in a superposition state of being able to fly and being unable to fly."
"How to say?"
Chen Nian looked at the B-2 in confusion. He felt that the other party's aerodynamic design still had a strong foundation. At first glance, although the entire fuselage was different from the real B-2, in order to adapt to the size of the turbojet engine, and thrust. The designer made some adjustments to the flying wing. The aspect ratio is larger and the lower arc is sharper. It should not be difficult to fly.
"It's not a problem with the flight control."
"You know, the flight control of the B-2 is very complicated. Anyway, this thing is fine without control. It can fly smoothly. If you want to turn in the air, you will fall down."
"We have no choice but to test a little bit and optimize a little bit. Maybe one day we can try this thing out."
Hearing this, Chen Nian couldn't help but admire him.
What is scientific research spirit?
These classmates of mine really regard scientific research as a form of entertainment that can satisfy themselves.
Just like Qian Xuesen was building rockets in the dormitory, they were also testing flight control on the lawn of the teaching building.
If there is enough time, maybe the results will improve step by step until a real B-2 flight control system is created.
This will definitely help the development of flight control in the entire country.
Chen Nian looked at Yu Yue sincerely and said:
"You guys are really awesome. If you make it, remember to report it to Professor Chen. Maybe we can give you a grand prize."
"Harm, no reward or no reward, it's just a joke."
Yu Yue waved his hand and suddenly changed the subject and said:
"Hey, seriously Chen Nian, can you come over and help? You are the best at pneumatics in our class. Can you give me some advice?"
Having said this, Chen Nian no longer refused. He followed Yu Yue and looked at them one by one, but as he looked at them, he suddenly felt that something was wrong.
There is a problem with the wing design of this aircraft. The sweep angle is too large. If you do this, the model aircraft will be fine. If it is a real aircraft, as soon as the speed increases, the turbulence will follow the wings and tear the tail into pieces.
This F-16 is no good either. The design does not capture the essence of static instability. It just has a similar shell. In this way, it is equivalent to giving up the F-16's large angle of attack vortex advantage, and the low-speed performance is reduced - -In order to make up for this, the designer adjusted the wing design of the aircraft, making the entire aerodynamic layout even more confusing.
No wonder it sways when it flies.
There is also the J-8. The design is okay, but the thrust of the aircraft model engine is actually more exaggerated than the J-8 itself. It can't even be called an airplane, it has to be called a rocket.
As for the Harrier, without a vertical take-off and landing function, its aerodynamic layout is completely cumbersome. It might as well be like the F-35.
etc?
Can I really name so many problems? !
Chen Nian was suddenly startled.
After more than a year of study, he has always felt that he is still a novice. The reason why he can give design suggestions is nothing more than the information advantage under the blessing of the system.
Therefore, when Yang Wei approached him and asked him to participate in the J-20 ship modification project, he was still a little nervous.
But today, at this moment, he suddenly discovered that he was no longer a useless newcomer!
As soon as I see the wings, a series of information about airfoil vortices is automatically generated in my mind; as soon as I see the belly of the aircraft, I start to think about the layout of the lifting body; as soon as I see the full-motion horizontal tail, I start to think about the control and fly-by-wire systems.
Moreover, the most important thing is that I actually still have ideas and ideas!
For some simple designs, it only takes a moment for the data to pop into my head naturally!
Damn it? !
A year of intense study finally paid off?
Coupled with the knowledge and experience of various technical analysis that I have integrated, my true level has actually reached a very high level now - it's just that I didn't know it before and had no confidence!
That being said, wouldn't he be able to try to design a ship-mounted model of the J-20?
Chen Nian felt excited and wanted to rush back immediately to give it a try, but since he had promised Yu Yue, he couldn't break his promise.
So, while walking around the venue, he opened his mouth and quickly asked the questions of these model airplanes one after another, like a roll call, which made everyone present stunned.
At first, some people thought he was just showing off.
But as he explained the problem in more and more detail, and as the model aircraft owner nodded more and more frequently, everyone could see it:
The thighs are coming!
What are you waiting for? If you don't hug me now, when will you wait?
As a result, more and more people gathered around him, and it took him more than an hour to finally explain all the models, and most of them also made suggestions for optimization.
Then, he said goodbye to everyone, left the lawn and walked home.
At this time, everyone on the lawn was still immersed in shock.
You know, what Chen Nian just commented on were all the model airplanes on this grassland!
It’s not a big deal to know one or two, and it’s normal to know a few systems, but you can understand them all and be able to give advice on them all.
That is true God.
Someone came close to Yu Yue and asked:
"Yu Yue, who is this brother? He is so awesome. He is from the junior class? A doctoral student? Can he be recruited into our club?"
Hearing this, Yu Yue shook his head and replied:
"You're not in the junior class, you're in the same class as me."
"It's just that people are different."
