Go back in time and be a chaebol

Chapter 420 Helicopter (It’s Chinese New Year, I wish everyone a happy New Year’s Eve)

I have to say, 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 something to be ashamed of.

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. Besides, he was studying airplanes and didn't have much connection with ordinary enterprises at all.

Yao Jie, whose wife was just pregnant with her second child, accepted the huge sum of one thousand yuan.

what?

Overkill?

Are you kidding me, money is good!

But 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!"

The idea came to him entirely because of a sudden thought. He just thought 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.

While sighing, Zhang Zili had already made up his mind - no matter what, he must let his children go to college in the future.

That day, when the new fan blew out a slow breeze, blowing the newspapers on the desk, and blowing on Zhang himself, feeling the refreshing but powerful breeze, he couldn't help but exclaimed.

Motor power reduced by 15%!

What's this!

This is money!

If it were true, it would not matter whether the first two requirements could be met. This alone would be enough!

"As expected of an expert who designed something, this thing... is so good!"

Holding back the excitement in his heart, Zhang Zili laughed:

"Mr. Yao, what you are saying is that for someone like you who makes aircraft propellers, designing fan blades is not a trivial matter."

Think about it, there is actually a lot of knowledge connected between propellers and fan blades. Compared with aircraft propellers, the technical content of fan blades is simply not worth mentioning. You can design it with just a little thought. Fan blades with stronger wind power and lower noise... But, which fan factory would think of finding such a designer?

At this point, Zhang Zili admired his own idea. In fact, the reason why he had such an idea was not because he had flown on an airplane. In fact, like many people, he had watched airplanes in movies.

Surprised, Zhang Zili was even worried that the other party might be fooling him.

"Director Zhang, don't forget that I'm in the propeller business. What I'm mainly researching now is helicopter propellers. Its technical content, well, even if you tell me, you don't understand it. To put it bluntly, an electric fan like the one you make, I can tell the wind direction and speed just by looking at the leaves. When I designed this, the curve of the leaves was precisely calculated. Although I have not personally tested it, I can guarantee that this fan will definitely be able to achieve the softness and softness you require. It is quiet and more power-saving. According to my calculations, using this blade, the power of the motor can be reduced by 15% while keeping the wind force unchanged."

"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!"

Despite this 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 is the wind blowing? It is 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 ask Mr. Yao to design a more efficient ceiling fan later.

Knowledge is wealth.

Zhang Zili finally understands this truth. Now that a master has been discovered, he must be put to good use.

……

Yao Jie, who was studying helicopter blades with his colleagues in the laboratory, couldn't help but sneeze. He didn't take it seriously. He looked at the air conditioner on the window and thought that the temperature of the air conditioner was set a little low.

Although the laboratory is very spacious, the temperature here is still pleasant thanks to the six window air conditioners, so that in many cases, graduate students are not even willing to go back to their dormitories, but directly make beds on the floor in the laboratory. After all, there are only fans in the dormitory.

"This S51 helicopter from Sikorsky 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 covered by two layers of fabric skin. ,..."

In the laboratory, when 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 No laminated wood.”

Yao Jie said directly.

It is no secret that wooden propellers are not suitable for Southeast Asia. After all, several military aircraft use wooden propellers, and they have encountered problems to varying degrees. Therefore, all military aircraft have now been converted to metal propellers.

"There are indeed hidden dangers in this regard,"

"Then we can only use all-metal propellers?"

"That's right,"

"In this case, it will need to be redesigned..."

Designing helicopters is a recent project jointly carried out by the Department of Aviation of Yong'an University and the Air Force. Last year, the Air Force purchased six S-51 helicopters from the U.S. Sikorsky Company. These helicopters are not only the first batch of helicopters for the military, although the military has also Used in testing and developing 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, and even the German professors in the department had no experience in teaching them, 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. The S-51 is obviously not suitable. We need to The components were rearranged, including relocating the engine and relocating the cabin and cockpit, further increasing the volume of the passenger compartment..."

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...
