Chapter 175 Aeroengines
A strong country must have a strong army, and a strong army can ensure national security!
On the news broadcast, the host started the report with this, and made a 1-minute report on the scene that took place in the military training at Shuimu University today.
Netizens did not expect that Qin Yuanqing would be on the news broadcast again, and everyone would become lively on the Internet. If it is a star, it is extremely rare to be on the news broadcast, but for Qin Yuanqing, it would be several times a year.
And it has been two months since the last news.
On the Internet, Qin Yuanqing has a very famous name as the best singer among scientists. Anyone who has heard Qin Yuanqing sing, there is no one who can say anything bad.
The best singing among scientists, and the best scientific research among singing.
It was Qin Yuanqing.
Even those who like music cried loudly and said that Qin Yuanqing is a great singer who was delayed by scientific research.
Of course, Qin Yuanqing has no feeling about being on the news broadcast. He will be happy and proud at the beginning, but it doesn't matter as the number of times increases.
Nothing to get excited about either.
When Qin Yuanqing returned to the office, he began to think about it. Whether it is the Automobile Research Institute or the Aeronautical Engine Research Institute, they need to go through the school council to discuss and form a resolution, and even go to the Ministry for filing before they can start, and these will take at least a week or even two weeks. to be completed.
Then Qin Yuanqing closed his eyes and immersed himself in his mind. The whole set of F119 turbofan engine technology. The F119 turbofan engine is a dual-rotor small bypass ratio afterburning turbofan engine. An engine to 20 degrees with thrust and vectoring controlled by a digital electronic system.Its thrust is 15 tons, which is actually smaller than the F135 engine, but Qin Yuanqing chose this engine in the end. The reason is very simple. The F135 engine was developed on the basis of the F119. Crossing the river and developing the F119 engine is a matter of course.
The more he understands the F119 engine, the more Qin Yuanqing is shocked by the technology of the United States. It is hard to imagine such an advanced engine. The United States conducted its first bench test in 1986 and successfully developed it in the 90s.
Therefore, it is not unreasonable for people to say that the Cold War was a period of human technological explosion.
In order to surpass each other, the two superpowers did not hesitate to invest in scientific research, and the result was the explosion of various high-tech, that is, the Internet was actually born in that era. Even though that era has ended for 20 years, the society is still benefiting today. in that era.
"America is really perverted. With such an engine, the F22 is paired with two F119 engines, and its combat effectiveness is beyond the charts!" Qin Yuanqing was shocked.
The maximum thrust of the F119 engine is 15.6 tons, the intermediate thrust is 10.5 tons, the total pressure ratio is 35, the bypass ratio is 0.3, the temperature before the turbine is 1577°C~1677°C, the maximum diameter is 1.13 meters, the length is 4.826 meters, and the weight is 1360kg.It can be said that this is an extremely advanced mature engine.
The entire F119 engine consists of a 3-stage fan, a 6-stage high-pressure compressor, an annular combustor with aerodynamic nozzles, a floating wall flame tube, a single-stage high-pressure turbine with a single-stage low-pressure turbine in the opposite direction to the high-pressure turbine, an afterburner and a two-dimensional Vector nozzle and other composition.The whole engine is divided into 6 units: fan, core engine, low-pressure turbine, afterburner, tail nozzle and accessory drive case, and there are also accessories, FADEC and engine monitoring system.
According to Qin Yuanqing's understanding, Pratt & Whitney invested a huge amount of US$25 billion in research and development that year before it was successfully developed.You must know that this is not the 25 billion US dollars today, but the 90 billion US dollars in the 25s. The US dollars at that time were very valuable.Pratt & Whitney is an engine giant with advanced engine technology, and has invested 25 billion US dollars on such a foundation.Now, if a country starts from scratch without investing hundreds of billions of dollars, it is estimated that it will be difficult to succeed.
One can imagine how difficult it is to develop an advanced aero engine.Otherwise, Huaxia will not have an engine that can reach the world's leading level. The "Kunlun engine" seems to have been installed on fighter jets, but it is actually far inferior to the F16 aero engine.
Aeroengines are impossible without investing a lot of manpower, material and financial resources, unless they have a system like Qin Yuanqing.
Sometimes having a system is so awesome, it can help the country save hundreds of billions of dollars in research and development costs at once.
And what's even better is that there is patent protection in the civilian field, but there is no such thing as patent protection in the military field.Even if he actually copied the F119 engine, the United States can only smash its teeth and swallow it in its stomach.
Fortunately, he exchanged the whole set of F119 aero-engine technology, otherwise, he would really start from scratch, and I don’t know how much time it will take. The high temperature performance of the material varies greatly.
A very important reason for the poor performance of Huaxia aero-engines is that the high-temperature-resistant materials of the engines are not good. For example, the temperature of the vortex front of the Kunlun engine is about 1300°C, which is about 119°C lower than that of the F500 aero-engine.And under the same circumstances, the higher the temperature, the stronger the thrust.
Moreover, the basic materials of aero-engines are only one aspect. Others also involve structure, airflow, etc. It is really a step-by-step research and development, which really requires a lot of manpower, material and financial resources. As for the engine, he directly declined, even if Qin Yuanqing is an academician. It is true that aero engines are not easy to play with.
"Hehe, it seems that this time there will be another big development in the high-tech field." Qin Yuanqing secretly thought that this high-temperature-resistant material can be used not only on military aircraft, but also on other aircraft, as well. in other fields.
Moreover, the requirements for processing F119 aero-engines are very high, and domestic processing equipment may not be able to meet them.
Qin Yuanqing took a look, it was already dark outside, and the clock on the wall pointed to 12 o'clock, only then did he realize that it was already 119 o'clock before he knew it.
After sorting out the materials on the table, he turned off the computer, turned off the lights in the office, and locked the door behind his back.
Looking at the two laboratories again, the lights in the laboratories have been turned off, but the office lights of graduate students and doctoral students are still on.
Qin Yuanqing then went upstairs. His group of graduate students and doctoral students were mainly engaged in research and development. As for the class, Qin Yuanqing only had two classes a week. Usually, if he had any questions, he would either ask other people for advice, or leave it to Qin Yuanqing when he was in class. .
Through the window, I saw a few people playing League of Legends. Qin Yuanqing smiled. League of Legends is very popular now and is very popular among young people. Tencent is making a lot of money with League of Legends.
In the school, there are often students who compete in dormitories as a unit, winning two out of three sets, and the losing dormitory treats guests to dinner.
Even, some boys cheated little girls by playing League of Legends.
Qin Yuanqing didn't bother them. As a former student, he knew this very well.Anyway, at this time, it is normal to play games and relax.
Qin Yuanqing told all graduate students on the first day that if he fails to pass the thesis in three years, he will leave his subordinates. If he fails the assessment every semester, the subsidy will be lowered. If he fails the assessment three times in a row, he will be left to fend for himself. .
Looking at the doctoral students again, Qin Yuanqing couldn't help but secretly nodded when he saw doctoral students reading books one by one. This sentence will never go out of style.
Compared with graduate students, doctoral students have more heavy scientific research tasks and need to consult a lot of materials. At this stage, they are not just listening to lectures, but they have to study on their own, acquire knowledge from the sea of books, and then gradually form their own opinions. own knowledge.
Even when Qin Yuanqing gave them lectures, he often mentioned that it is better to have no books than to have no books, and one must be good at thinking. Even what he teaches is only reasonable for now, and it may not be suitable in a few years.
The most important thing for mechanical doctoral students is to participate in research and development. As long as they participate in research and development with heart, there will be no shortage of high-quality papers. The most important thing in Qin Yuanqing's laboratory is papers. His two laboratories have been in the past year. The papers produced are quite objective, and several of them have been published in the highest-level professional journals.
As for the doctoral students in mathematics, Qin Yuan set up the research objects early in the morning. They are all mathematical problems in their respective fields. As long as they solve the mathematical problems he arranged, they can graduate with a doctorate.
In the past period of time, the doctoral students under him have obtained marriage certificates one after another, even graduate students, and several of them got married.But getting married is relatively simple, get a certificate, then treat everyone to a meal, and introduce the other half to everyone.
Qin Yuanqing stayed for a while, then went home.
When he got home, Qin Yuanqing was taken aback when he saw that cute Ferrari parked in the parking space. When did Jing Tian come back?
Although Jing Tian didn't make a movie during this time, he was doing commercial performances and appearing on TV everywhere, like a trapeze artist, and Jing Tian is currently recruiting troops, so busy that Qin Yuanqing didn't even know she was coming back today.
Picking up the phone quickly, he saw several missed calls and hundreds of messages, Qin Yuanqing couldn't laugh or cry, he was so immersed in his thoughts that he even blocked the outside world.
His mind was running quickly, and after 1 minute, thinking of how to deal with it, Qin Yuanqing got out of the car with a bright smile on his face and walked towards the house.
Such a simple matter can't help Qin Yuanqing, who has an IQ of over 200. Just kidding, isn't it just that he didn't answer the phone, didn't he just not reply to the message, what's the big deal.
Qin Yuanqing hummed happily, opened the door and walked in.
