In this way, von Kármán and Plante became the first to be invited to China. .v d . m

When he came to China, in order to show his attention to the two, Zhang Yi asked Liang Qichao, Cai Yuanpei, Einstein, and Planck to accompany him, and personally received von Kármán, Planck and the two assistants who accompanied him at the presidential palace.

After the outspoken Plante saw Zhang Yi, the first thing he said was, Mr. President, where is my plane?

Zhang Yi was stunned for a while, and immediately reacted, this guy is too anxious, right? I have just arrived in Beijing, and it is like asking for a plane by myself.

Zhang Yi said with a smile: "Mr. Plante, don't worry, since I promised you, I will definitely do it, at Beijing Nanyuan Airport, there are dozens of various types of aircraft, as long as you want, you can go to pick it up at any time, today is an important moment for you to come to China, this is a reception banquet, although we let go of our minds, haha." ”

Plante's face turned red and he replied: "Mr. President, to tell you the truth, the subject I am currently studying urgently needs the support of aircraft, and there are many kinds of data, because I cannot come out without the verification of aircraft flights." In Germany, the aircraft has been regarded as a treasure by the military, and there are many monks and little porridge, and they will only be allowed to be used when they are carrying out relevant major projects, and they have to go through layers of approval, which is very troublesome and seriously interferes with the progress of our research, so I am anxious, please forgive me. ”

Zhang Yi waved his hand and said: "Mr. Plante, you are polite, you are a guest from afar, you are the guest we invited, naturally I will do my best to support your scientific and technological research, not to say that it is one plane, it is ten planes, as long as it is helpful to your subject, I will definitely not be stingy!" ”

Seeing Zhang Yi's attitude, Plante was relieved.

Plante continued: "There is one thing, Mr. President, that I need to say earlier, and that is that I am German, of pure Germanic descent. I cannot refuse the call of my country at a particular moment, and if the country needs it, I ask you to allow me to return to Germany, which I have requested in advance, and I am here only to advance the subject I love! ”

Zhang Yi was stunned for a moment, and then smiled secretly. Other kinds of people are not easy to deal with, to those of you who only have scientific research in mind. I don't care about anything, as long as I use a little trick, you just want to go, but I'm afraid you can't go, there is a delicious bait hanging in front of you, I'm still afraid that your little fish will run away?

Zhang Yi said: "Mr. Plante is the so-called science has no borders, scientists have borders, I understand your request very much. As long as your country calls you and you yourself are willing to return to China, I will never stop you, which is the greatest respect for you and the best respect for our friend Germany. ”

Plante whispered: "Thank you, thank you, Mr. President, for your understanding!" ”

Zhang Yi continued: "I heard that Mr. Plante has a very high degree of attainment in aerodynamics and fluid mechanics, and he is a leading university scholar. I would like to ask what is the most important in the application of aerodynamics? ”

Plante was stunned for a moment and hesitated: "This, Mr. President, no matter what field it is." The theory of any discipline is equally important, the advent of a new invention is inseparable from any required technology, such as an airplane, his engine technology is important, his propeller manufacturing technology is also very important, and the shape of the wing is equally important to the flight of the aircraft. In the future, there may also be applications in communication equipment......"

Zhang Yi nodded and replied: "Mr. Plante is worthy of everyone's words, with a unique vision, what you said is very reasonable, but what is the basis for this?" Aircraft, only with aircraft, these technologies can have a better place, but the development of aircraft is a comprehensive project, which involves the various technologies you said, in addition, there is the application of aircraft fuselage material technology, the future fuselage materials will definitely develop towards strong and lightweight, and then there is the plasticity and ductility of materials, but these must be based on the research of aircraft, the development of aircraft is not a simple problem, which involves too complex academics, If you want to apply all these engineering technologies to the aircraft, it takes a lot of manpower, force, and we can't guarantee that it will succeed, which requires us to be able to grasp some of the key data before we build the aircraft, such as the power parameters of the engine, such as the force in flight of the fuselage, and the impact of the propeller and the wing and fuselage on air resistance. Is there a way to achieve this in the early stages? ”

Plante was stunned, this, he didn't think about it, after all, he didn't come from the development of aircraft, and the aircraft had just been launched for three or four years, so he could understand it so deeply?

Plante asked, "What do you mean, Mr. President?" ”

Zhang Yi said with a smile: "In fact, we can establish a facility that can fully simulate the data characteristics of various climates and weather conditions, and conduct relevant scientific experiments before the aircraft is produced, so as to test the relevant data of our related technical products under various climates, especially under severe climates, and provide data support for the development and manufacturing of aircraft!" ”

Plante's eyes lit up, yes, not only airplanes, but also other engineering equipment can also be taken to this kind of facility for testing, once this kind of facility comes out, it will greatly reduce the probability of failure of engineering research, which is of great significance for scientific research!

Plante clapped his hands and praised: "Mr. President, I still don't believe that you are a scholar with advanced attainments in science and technology, and today I know that I am shallow, I want to sincerely apologize to you, this kind of facility you said is too important, once the research is successful, it will be of great significance to the progress of scientific research!" ”

Zhang Yi smiled: "Mr. Plante is false, I really don't dare to be, you are a famous aerodynamics expert, but also a fluid mechanics expert and a meteorology expert, you are the most appropriate to do this job......

Plante stood up, his eyes lit up, and shouted: "Mr. President, you have pointed out a clear path for my scientific research, and also for the world's scientific research, thank you so much, I will be responsible for this work, leave it to me, I will definitely not disappoint your expectations!" ”

Not only Plante, but even Einstein and Planck on the side were all shocked, this president is really a freak among geniuses, he either doesn't speak, and once he speaks, it will definitely cause a sensation! The construction of such a facility is so important for aerodynamics and even for the future of aviation technology!

Zhang Yi ignored everyone and replied calmly: "I have already named this kind of facility, call it the wind tunnel!" (To be continued.) If you like this work, you are welcome to vote for recommendation and monthly passes, and your support is my biggest motivation. )
