Chapter 657: The ignorant is fearless

"Uh, this, Mr. Lu, I don't quite understand what you mean?" Tan Zhenhua was a little confused by Monk Lu Hesheng.
Lu Hesheng stared into his eyes and said solemnly: "Eric, your drone uses a typical multi-rotor structure. Since the aviation industry, the multi-rotor structure has been a classic problem, so When I saw the sketch of the drone, I was puzzled at first sight. Is this really something a teenage boy made? And when I got the real thing, I became more determined. , This is by no means a job that a child can complete."
It turned out to be so.
Tan Zhenhua secretly praised that Lu Hesheng is worthy of being a veteran driver who has been immersed in the aviation industry for many years. He can see the strangeness of this drone at a glance, and he also explained the essence of Tan Zhenhua's reputation.
On the surface, Lu Hesheng only questioned that Tan Zhenhua could not rely on a single person to make a 4-rotor drone. If you think about it, you will find that he is still questioning another more critical issue: Is Tan Zhenhua misappropriating? Other people’s research and development results and take them as their own, if that is the case, the nature of the matter is completely different!
Tan Zhenhua knows deeply that for this kind of older "old school" scholars, misappropriating the research and development results of others is absolutely intolerable, because that shows the bad nature of this person!
Even with his toes, Tan Zhenhua knows that once Lu Hesheng is deemed costly, then a series of plans for Lu Hesheng that he wants to launch later will be impossible to carry out, and even the future contacts with Vivian will be severely affected. Obstruct!
However, since Tan Zhenhua had known the key points of this meeting from Vivian, of course he had already prepared for it.
"Old Lu, what you said is all right." Tan Zhenhua came up to affirm Lu Hesheng's guess and said with an expression of admiration: "Actually, I just finished the initial work and designed the original structure for this prototype. Let it fly successfully. After that, a team from Ningdu University of Aeronautics and Astronautics further designed and improved it. The tutor leading this team is the current vice president of Ninghang University, Professor Guo Rongwei. You may listen His name?"
Tan Zhenhua did not hesitate to use Guo Rongwei, his teacher, as a shield.
"It turned out to be so, it's no wonder." After thinking for a while and didn't find any obvious logical loopholes in Tan Zhenhua's narration, Lu Hesheng accepted this sounding reasonable explanation, and he relaxed a little and said: "Professor Guo I've heard of this person, his knowledge in the field of drones should be regarded as the first person in China, right? If he is the leader, then it's justified."
Tan Zhenhua hurriedly climbed along the pole: "Yes, the prototype I built can only stay in the air for no more than 5 minutes, and its flight performance is also very bad. However, after the team led by Professor Guo took over, it was not only successful The space time has been increased to more than 15 minutes, the attitude control ability of the flight has also been greatly enhanced, and the camera function has been added to it, which makes it have practical value. The mass-produced model is based on the improvement of Professor Guo As a result, as for my prototype, it can only be regarded as a crude toy."
There was a smile on Lu Hesheng’s face. Tan Zhenhua’s statement was very close to his previous speculation, and the young man was also quite honest. When he asked himself, he told the story of the matter as it was, and admitted honestly. In fact, Professor Guo Rongwei of Ning Hang has made the biggest contribution to the epoch-making product of the 4-rotor UAV, which made him a new level of favorability for Tan Zhenhua.
At least this is an honest kid, he thought.
As for why the 4-rotor UAV finally applied for a series of patents in the name of Tan Zhenhua, he automatically thought that it should be due to some arrangement of China. Because based on his own information, the United States purchased a large number of such drones from China through a certain United Nations aid fund and gave it to Pakistan Railways to participate in the war against Soviet Russia in Afkhan, and the information returned was It shows that the user's response to the product is quite good, and they are looking for further additional orders-since it is a business that can earn US dollars, it is understandable for China to deal with it this way.
Taking advantage of the increase in Lu Hesheng’s interest in him, Tan Zhenhua hurriedly flattered and said: "Old Lu, I heard Vivian say that you are now the chief engineer of Grumman, and I have heard of Grumman, so The research, development and production of fixed-wing fighters is the main focus. It shouldn't have been involved in the field of rotorcraft. Mr. Lu, you know so much about rotorcraft. It's amazing!"
"I really don't understand rotorcraft. I just learned a little bit of common sense out of professional needs." Lu Hesheng said, but the expression on his face revealed a bit of pride: "In this respect, it is Hughes. Sikorsky and Bell are stronger. Our Grumman is best at fixed-wing fighters, especially carrier-based fixed-wing fighters."
"Lao Lu, what do you mean by "multi-rotor structure is a classic problem in the aviation industry"? In my impression, the U.S. aviation industry has always been at the forefront of the world. Why is this multi-rotor structure? No one ever tried to succeed?" Tan Zhenhua asked with ulterior motives. In fact, the biggest purpose of what he did was to gradually divert Lu Hesheng's attention.
"This, it's not that no one has tried it. How come Eric, you have come up with the prototype of the 4-rotor drone, don't you know the ins and outs of this structure?" Lu Hesheng asked suspiciously.
Tan Zhenhua quickly explained: "Lao Lu, I really don’t understand. When the prototype was made, it was only considered that the rotation of the rotor in one direction would inevitably bring a rotational torque. In order to balance this torque, some measures need to be taken— —I thought at the time that the lift of a motor to drive the rotor was not enough. It would be too cost-effective to add dead weight to it to balance the torque. It is better to add a counter-rotating motor and rotor on the opposite side. It can not only generate more lift, but also solve the problem of torque. Isn't that killing two birds with one stone? That's it, and in the end it becomes a 4-rotor."
Lu Hesheng stared at him for a while, then suddenly smiled: "So this is the so-called "the ignorant is fearless"? You don't know the difficulties of the multi-rotor structure, but you do not want to make a mistake. Proposed a solution to a problem that has plagued the aviation industry for decades, and even verified it on a micro system. It seems that you are also a destined person, even if it is early today, I will tell you about this. The history of multi-rotor development will also prevent you from revealing your stuff next time you brag."
This is... was ridiculed and despised by the old man? Tan Zhenhua was secretly happy, but he successfully evoked Lu Hesheng's chat, and it was considered to have achieved his goal, so he put on the appearance of sitting upright and listened.
