The busy time always seems very short, and in a blink of an eye, another golden autumn is here.
When they enter their junior year, many students are faced with a choice: work after graduation, take the postgraduate entrance examination, or secure a postgraduate degree.
Some people start preparing for the postgraduate entrance examination as early as their sophomore year, and it cannot be later than their junior year. If it is later, there will not be enough time.
Of course, the best time to prepare for the postgraduate entrance examination is the junior year: there are too many basic professional courses in the sophomore year, and the curriculum is somewhat intensive; when the junior year enters the professional course stage, most of the courses studied have nothing to do with the postgraduate entrance examination and the curriculum is relatively sparse...
As for those who only prepare for the postgraduate entrance examination in their senior year, apart from being academic experts, they are just scumbags: they only prepare for three or four months before taking the exam, which most people cannot handle.
Zhou Yan did not need to consider the postgraduate entrance examination. He had perfect scores in all courses. As soon as he entered his junior year, he was favored by many master's tutors in the school.
Zhou Yan had no plans to go abroad or change schools, so he naturally agreed to the invitation of the head of the department who would lead graduate students.
The classrooms for graduate students have been decided, but you still have to learn the courses you should take in your junior year.
Although Zhou Yan's own aircraft design skills are not bad, he is a monk halfway: the design skills inherited from the dragon knight Lin Mo are all acquired by riding a dragon and blowing the wind. Most of them are low-altitude and low-speed experience, high-altitude and high-speed aircraft design experience, and also
All are self-taught.
Now that he has the opportunity to re-solidify his foundation, Zhou Yan will naturally not waste the opportunity.
With courses such as flight mechanics, flight structure mechanics, and aircraft structural design, every day is new for Zhou Yan.
Although he is still studying, Zhou Yan, who has a certain professional foundation and has built himself professional tools, is still as comfortable as a duck in water.
Although the involution of undergraduate graduates in the first decade of the 21st century was not that severe, there are already signs of involution under the instigation of a certain butterfly wing.
Professional software ANSYS, ABAQUS, etc., which originally appeared only after employment, have already entered the school dormitories.
Although there are fewer courses in his junior year, Zhou Yan is still as busy as before: he either needs to help his classmates deal with finite element models, or he needs to simulate the flow fields of major well-known aircraft.
There are five types of aircraft that Zhou Yan focuses on: F-15, F-16 and F-22 equipped by the Chinese Air Force, and A/F-18E/F and F-35 equipped by the Navy.
Zhou Yan did not simply simulate the flow field of the fighter jets at various airspeeds when they were unloaded. To meet the needs of actual combat, Zhou Yan simulated the flow fields of these five types of fighters under various mounting conditions.
Of course, Zhou Yan also did not miss the electromagnetic stealth tests of the F-22 and F-35.
At present, the F-22 has just formed into the army, shrouded in the so-called "4S" halo, and still covered with a veil of mystery.
Zhou Yan used the meter wave radar and took off Miss F-22's invisibility coat.
It’s a good article, so naturally it should be shared with everyone.
Zhou Yan compiled various simulation results of the F-22 into a paper and published it in the domestic "Aircraft Design" magazine.
At this time, many knowledgeable people across the country were still shrouded in the shadow of the "generation gap" caused by the fourth-generation aircraft: there are generation differences in aircraft, and the number cannot be filled. Zhou Yan's "wonderful article", Luoyang Zhigui,
Everyone is proud to own a copy of Aircraft Design magazine.
In just one month, Zhou Yan's paper was reprinted in major military magazines and periodicals.
This was not over yet. Less than a month after the paper was published, the department of Zhou Yan’s old boss Liu Jingguo invited him to have tea.
In order to maintain the authority of his paper, Zhou Yan had to expose the basically completed cloud service system - "Honghuang".
Seeing the virtual cloud server that Zhou Yan had set up with free votes, the intelligence officers responsible for the investigation were all shocked: Can you still have sex for free?
After being targeted by the intelligence agency, the source code of "Prehistoric" could basically not be saved. After returning to school, Zhou Yan immediately made a backup and dedicated it to the school.
Within a week, an aviation company responsible for "Aircraft Design" supported Zhou Yan's paper: the various data used in the paper were basically consistent with the research data of the company's Radar Research Institute.
After that, a large wave of royalties came to Zhou Yan like a storm.
When some people are in such a bright moment, lemon juice will naturally pop out.
"Classmate Zhou Yan, you will never be able to study in a beautiful country in this life!"
At such a moment, Zhou Yan and Zhou Daodu naturally fought back.
“Studying in a beautiful country is originally a glorious and sacred thing.
More than 130 years ago, at the insistence of its foresighted predecessors, the Qing Dynasty, which was on the verge of decay, successively sent four batches of 120 young children to the beautiful country.
Except for a few who died early, stayed in the United States and never returned to their hometowns, these children eventually grew up and returned to the motherland, contributing indispensable forces to the modernization of our country.
It is the instinct of animals to seek advantages and avoid disadvantages, and the reason why humans are human is because humans are creatures with perseverance and ideals.
Nowadays, the gap between the two sides of the Pacific is no longer as big as it was more than a hundred years ago, but for the same foreign students, today, more than a hundred years later, do people still have the same persistence as they did a hundred years ago?
To this day, it is still an outdated saying to learn skills from barbarians in order to defeat barbarians, but how many people have become the saying that they should learn skills from barbarians in order to control themselves?"
As soon as Zhou Yan's "advocate" came out, many people fell silent.
On the Internet, there used to be many international students who cited "the country cannot provide a suitable scientific research environment" as the reason. However, these people seem to have forgotten that how could there be a scientific research environment in the Qing Dynasty more than a hundred years ago?
They were also foreign students. The group of foreign students headed by Mr. Qian in the early days of the founding of the People's Republic of China faced a poor country with no scientific research environment after returning to China. However, these people built the country's national defense system from scratch...
As long as your thinking doesn't slip, there are always more solutions than difficulties.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! For international students, as long as they want to do it and work hard, there should be no difficulties that can hinder them.
In fact, the most critical question is whether you want to do it or not.
Soon, Zhou Yan had no time to discuss the issue of studying abroad with some people who thought that the moon in the United States was rounder: "Aircraft Design" invited him to "evaluate" the JSF fighter F-35, which was not yet finalized by the Chinese Navy.
This really tickled Zhou Yan's skin.
Zhou Yan, who is familiar with "history", naturally understands the reason why the F-35 has not yet been finalized: the two types of engines participating in the engine bidding, the F-135 and F-136, have not yet been ranked.
In fact, the US Arms Procurement Committee has already decided on the F-135 for a ridiculous reason: the competing F-136 is a joint venture between GE and RR.
Despite this, the F-135 equipped with the Feidian F-35 has become the first aircraft in the world with a thrust-to-weight ratio of more than 10 due to continuous improvements after winning the bid.
Of course, Feidian's F-135 engine is also within the scope of Zhou Yan's "deep exploration": this type of engine reduces its own detectable infrared signature with a power loss of two to three percent.
Although the F-35 is claimed to be a single-engine reduced version of the F-22, there is a big difference between the two in terms of detectability: because of their different physical strength, under the same meter-wave radar exposure, the smaller F-35 will be alerted
35 reflected wave number, unit size is much smaller than F-22.
As for aerodynamic performance, although the single-engine and "fat" F-35 is equipped with a turbofan engine with the highest thrust-to-weight ratio, its overall maneuverability is much weaker than that of the F-22 equipped with a vector engine...
