Chapter 540 He Agreed
Sergey Izotov took the materials handed over by Yang Zhijun and read them.

As the top aviation technical personnel trained by the former Soviet government, Sergey Izotov's English level is of course no problem, but after a while, Sergey's brows frowned, and he raised Yang Zhijun's eyebrows: " You said that your company is the world's largest manufacturer of plant protection drones?"

"Yes," Yang Zhijun nodded affirmatively and said, "Looking at the world, in the field of plant protection drones, our company's products have the largest payload, followed by Dongying Yamaha's R-50, but the Yamaha R-50's The maximum load is only 10 kilograms, so in the segmented field of 'plant protection drones', our company's products are the best in the world today, and also have the largest production capacity."

Looking at Yang Zhijun with an expression of "I'm very proud!", Sergei Izotov was speechless for a while, not knowing what to say.

From the point of view of helicopters, Sergei Izotov does not think that Huateng Industrial Group's plant protection unmanned helicopter is called a "helicopter". A "larger aircraft model" was able to sell more than 300 aircraft in just half a year, and created a turnover of 1500 million US dollars including the provision of plant protection services, which completely surpassed Sergey Izzo Tove's imagination made Sergei Izotov unable to help wondering if there was something wrong with his perception of the world...

wrong!

Sergey Izotov came to his senses suddenly, and then asked Yang Zhijun, "Then, why are you looking for me..."

Yang Zhijun did not hide anything, and said: "Through the application in the past six months, we found that the operating efficiency of our current unmanned plant protection helicopter is still too low. Later, we calculated that if we can find a way to increase the load to 100 kg, An operating area of ​​about 1000 to 1200 mu can be achieved per hour, and the average daily operating area can reach about 7000 mu. However, for such a large operating area, remote control is not as cost-effective as manned helicopters..."

Sergei Izotov immediately understood what Yang Zhijun meant: "So you want to develop a manned helicopter?"

"Yes," Sergey Izotov nodded, and said, "We have done calculations, because it is a field operation, so this helicopter does not need to pursue any endurance or high speed. In this way, An ultra-light helicopter with a maximum take-off weight of about 600 kilograms is enough, and in order to reduce costs, we can even use piston-type aero engines, and the power required does not even exceed 100 horsepower."

"I understand what you mean," Sergey Izotov nodded: "So you want me to be the designer of this aircraft? Sorry, although I have some achievements in helicopter aeroengines, the engine There are two directions with helicopters, if you want to do this project, you can go to Miri Design Bureau or Kamov Design Bureau to find a way..."

"No, Mr. Izotov, you misunderstood." Sergey Izotov was interrupted by Yang Zhijun before he finished speaking. Looking at Sergey Izotov, Yang Zhijun said sincerely: "We The reason why I came to visit you is to ask you to come out and serve as our chief aero-engine designer and chief consultant."

"Cough cough...cough cough..."

Before Yang Zhijun could finish his sentence, Sergei Izotov, who had just picked up his coffee and was about to take a sip, coughed violently.

joke!

This is an aero engine, something that can only be played with the strength of a country. Is it something that your company can develop if it wants to?
Not right either!
Thinking of the identity of this local state-owned enterprise of Huateng Group, Sergei Izotov suddenly realized: Maybe this Huateng Industrial Group is actually a pilot unit quietly set up by the Huaxia government?If this is the case, then many things that don't make sense can make sense.

Seeing Sergey Izotov coughing, Yang Zhijun immediately kept silent, he understood why the old man's reaction was so intense.

This is indeed the case. After coughing for a while, old man Sergey Izotov stopped and looked at Yang Zhijun with a strange expression: "This Mr. Yang, what kind of engine are you planning to develop? Similar to For our Soviet TV3-117 series?"

"Of course not," Yang Zhijun shook his head hastily: "We want to develop heavy-fuel aviation engines."

"Heavy oil aircraft engine?"

Sergey Izotov froze for a moment, Yang Zhijun's answer was beyond his expectation once again.

Yang Zhijun nodded, and answered in the affirmative: "Yes, heavy fuel aero-engine."

"You really...really..."

Sergei Izotov shook his head, not knowing how to answer for a while, the news revealed by Yang Zhijun was indeed beyond his expectation.

The so-called "heavy oil" is of course relative to "light oil" such as gasoline, but in the field of aviation, the so-called "heavy oil" is not the sticky, asphalt-like heavy oil used in ships, but refers to Diesel or aviation kerosene, and in today's world, almost all piston aircraft engines are gasoline engines, and it is almost impossible to find aeroengine products that use heavy oil such as diesel and aviation kerosene.

Some students should be curious, since there are already mature piston-type aero engines fueled by aviation gasoline in the world today, why does Zhang Qihang start from scratch to make heavy-oil aero engines?What are the advantages of heavy oil engines compared to traditional gasoline aeroengines?
If we want to talk about the advantages of heavy fuel oil aero engines, we must first understand the shortcomings of gasoline. Only after understanding the shortcomings of gasoline can we understand why Zhang Qihang wants to use heavy fuel oil aero engines.

What are the disadvantages of gasoline?
Almost everyone knows that gasoline is flammable, explosive and volatile. There are many videos and examples of cars that have spontaneous combustion accidents burning themselves into a big fireball in a very short period of time.

These disadvantages of gasoline have all become the advantages of aviation kerosene: non-flammable, non-explosive, and non-volatile. That is to say, compared with aviation gasoline, aviation kerosene is much safer than aviation gasoline whether it is transported, stored or used. And for things flying in the sky, nothing is more important than safety.
