Chapter 420 Helicopter (It’s Chinese New Year, I wish everyone a happy New Year’s Eve)
I have to say that sometimes, money really smells good.
As a young university teaching assistant, even though his monthly salary was more than one hundred yuan, he still couldn't resist the temptation of a thousand yuan.
Turning knowledge into wealth is definitely not a shameful thing.
In fact, unlike the high-minded academic circles in Tangshan, Nanyang encourages scholars to apply their knowledge and turn knowledge into wealth. This is also the fundamental reason for issuing patent rights and establishing a patent office.
In the past few years, universities and enterprises, and scholars and enterprises, have long had close cooperative ties, and both parties are accustomed to such cooperation.
However, all this seems to have nothing to do with Yao Jie. Although he has participated in corporate-led research, he has just participated. Moreover, he was studying airplanes and didn't have much connection with ordinary enterprises at all.
The huge sum of one thousand yuan made Yao Jie, whose wife was just pregnant with her second child, choose to accept it.
What?
Overkill?
Are you kidding me, money is good!
In just a few days, Yao Jie used his spare time to come up with his design plan. In the simple office of Haomeng Electrical Appliance Factory, Zhang Zili said in surprise when Yao Jie unfolded the drawings.
"Mr. Yao, you got it done so quickly!"
Being surprised, Zhang Zili was even worried that the other party might be fooling him.
"Director Zhang, don't forget that I am engaged in propellers. What I am mainly researching now is helicopter propellers. Its technical content, well, even if you tell me, you don't understand it. To put it bluntly, like you are doing That kind of electric fan, I can tell the wind direction and speed just by looking at the blades. The curve of the blades I designed is precisely calculated. Although I have not personally tested it, I can guarantee that this fan will definitely work. It can achieve the softness and quietness you require, and it is also more energy-saving. According to my calculations, using this blade, the power of the motor can be reduced by 15% while keeping the wind force unchanged. ”
Motor power reduced by 15%!
What is this!
This is money!
If it were true, it wouldn’t matter whether the first two requirements could be met. This alone would be enough!
Suppressing the excitement in his heart, Zhang Zili laughed:
"Mr. Yao, what you are saying is that for a person like you who makes aircraft propellers, designing fan blades is not a trivial matter."
Think about it, propellers and fan blades In fact, there is a lot of knowledge related to each other. Compared with aircraft propellers, the technical content of fan blades is simply not worth mentioning. With just a little thought, you can design a fan with greater wind power and less noise. Fan blades... But, which fan factory would think of finding such a designer?
At this point, Zhang Zili admires his own idea. In fact, the reason why he has such an idea is not because he has flown on a plane. In fact, like many people, he just watched it in the movie. Pass the plane.
The idea came to him entirely because of a sudden thought. He just felt that the wind emitted by airplane propellers was so strong that it should also be used in electric fans. But he himself didn't expect that there was really a connection between the two, and that the other party could actually design a new wind leaf in just a few days.
That day, when the new fan blew out a slow breeze, blowing the newspapers on the desk, blowing on Zhang himself, feeling the refreshing yet powerful breeze, he couldn't help but exclaimed .
"As expected of something designed by an expert, this thing... is so good!"
While sighing, Zhang Zili had already made up his mind - no matter what, he must let his children go to college in the future.
“One thousand yuan for five days...”
Although he paid happily, Zhang Zili was still a little heartbroken.
"His grandma, it's true what His Majesty said, knowledge is wealth. Five days and a few drawings are worth a thousand yuan! You must go to this university no matter what!"
< br>
Despite such emotion, Zhang Zili did not regret at all. He even regretted that it was too late for this unexpected thought. It would have been better if it had been earlier... "What's the wind blowing? It's clearly money..."
Enjoying the gentle breeze from the electric fan, Zhang Zili's eyes were filled with the desire for wealth. At the same time, he had already made up his mind to let Yao Yao go back. Sir designs a more efficient ceiling fan.
Knowledge is wealth.
Zhang Zili finally understands this truth now. Now that a master has been discovered, he must be put to good use.
...
Yao Jie, who was studying the helicopter blades with his colleagues in the laboratory, couldn't help but sneeze. He didn't take it seriously and looked at the air conditioner on the window, thinking it was the temperature of the air conditioner. The tone is a little low.
Although the laboratory is very spacious, under the influence of six window air conditioners, the temperature here is still pleasant, so that in many cases, graduate students are not even willing to go back to the dormitory, but directly Make a floor in the laboratory, after all, there is only a fan in the dormitory.
“Sikorsky’s S51 helicopter is really good. The design of this blade is indeed very clever. The blade is composed of metal girders, plywood ribs and grooves. The entire blade is made of Covered with two layers of fabric skin,..."
In the test room, facing the blades of the S-51 helicopter, everyone was amazed and discovered its problems.
"This blade is good, but it is not suitable for Nanyang. Like the tail propeller, it is made of laminated wood. There is a lot of rain in Nanyang. If a laminated wood propeller is used, it will inevitably be corroded by rain. The helicopter we developed will definitely You can't use laminated wood."
Yao Jie said straightforwardly.
It is no secret that wooden propellers are not suitable for Nanyang. After all, several military aircraft use wooden propellers, and they have encountered problems to varying degrees. Therefore, now all military aircraft have been modified to Metal propeller.
“There are indeed hidden dangers in this regard,”
“Then can we only use full metal propellers?”
"That's right,"
"In this case, it will need to be redesigned..."
Designing a helicopter is the latest project jointly carried out by the Department of Aviation of Yong'an University and the Air Force. Last year, the Air Force obtained a new design from the United States Sikorsky purchased six S-51 helicopters, which are not only the first batch of helicopters for the military, although the military is still testing and developing uses for the helicopters. However, the military has decided to develop helicopters, so the military chose to cooperate with several universities.
Because they had no experience in designing helicopters in the past, even the German professors in the department had no experience in this area, they had to use the S-51 helicopter as their teacher, conduct in-depth research on it, and then design their own helicopter.
“Not only the propeller, but also the structure of the helicopter, we must also consider it. The military’s requirements are very clear, which is a helicopter that can carry ten people or the same weight of cargo, and the S-51 obviously does not If it is suitable, we need to rearrange its components, including the position of the engine and the position of the cabin and cockpit, so that the volume of the passenger compartment is further increased..."
In this way, a group of professors, teaching assistants and graduate students from the aviation department gathered around an S-51 helicopter that had been torn into pieces. They were talking to each other and drawing sketches on the drawing board from time to time. , and soon the outline sketch of a helicopter appeared...
