Chapter 673 Show off?

In the design and development center of Huateng Industrial Group, looking at the engine on the test bench, Hu Jihong was a little puzzled, and even more amused: "Secretary Liu, is this engine your group is developing? This... looks quite unique." ..."

Why do you feel strange?
Because the engine in front of me is quite different from the engine Hu Jihong has seen. First of all, it is a 4-cylinder engine with a V-shaped structure. The V-shaped cylinder structure is not unusual, and the four-cylinder is not unusual. It is too strange that the structure is associated with the four-cylinder. You must know that in order to control costs, basically all four-cylinder engines adopt an L-shaped structure, so that four four-cylinders can use one set/two sets For intake and exhaust camshafts, if a V-type four-cylinder is used, two sets/four sets are required, which increases the cost virtually. This is also the reason why inline four-cylinder gasoline engines have become popular in recent years. Can't see, Huateng Industrial Group is showing off their brains?Actually come up with a V shape?
Secondly, on the position of the cylinder wall, Hu Jihong also saw a large area of ​​heat dissipation fins that can only be seen on air-cooled engines, but if this engine is an air-cooled engine, there are connected heat dissipation fins on the engine. water tank, so it's an air-cooled hybrid water-cooled engine?
V-shaped four-cylinder plus air-cooled and water-cooled cooling methods, Hu Jihong thinks that Huateng Group is either out of their minds, or they have too much money and no place to spend. With this structure, the overall manufacturing cost is higher than the most common in-line How much higher is the manufacturing cost of a four-cylinder liquid-cooled engine?

More than 20%, right?

Liu Jianfeng is not stupid, how could he fail to hear the irony in Hu Jihong's words?However, he didn't take it seriously, and nodded with a smile: "This is a piston-type aircraft engine developed by our Huateng Industrial Group that uses aviation kerosene as fuel. It has just completed the ground bench test."

The smile on Hu Jihong's face suddenly froze: Is this an aero-engine?And it still uses aviation kerosene as fuel?
Unbelievable Hu Jihong sniffed carefully. Indeed, although there is a faint smell of exhaust in the air, it is not the smell of diesel engine exhaust or gasoline engine exhaust... Who didn't smell the exhaust of tractors and 212 jeeps when they were young?

Although the smell of this exhaust gas is very strange, in turn, it seems to just prove that the fuel of this engine seems to be aviation kerosene.

"Secretary Liu, you guys..." Pointing to the engine in front of him, Hu Jihong couldn't understand: "What are you building this engine for?"

"It's for supporting our group's helicopters," Liu Jianfeng said as a matter of course: "A piston aero engine of the same power in the world costs about 30 yuan in RMB, and it can only be bought in US dollars. , Mr. Zhang said that the engine is not a particularly advanced thing, and in order to ensure the safety of the fuel, let's just build a piston-type aircraft engine that uses aviation kerosene, so we have this..."

Hu Jihong was shocked: "Your group is developing helicopters?"

"Of course!" Liu Jianfeng said proudly, "And to tell you the truth, Secretary Hu, we have already built a prototype, and now our flight test team is taking helicopters to test flights across the country to collect evidence."

Huateng Industrial Group is actually developing helicopters? !
And has entered the test flight certification stage?

Seeing the undisguised pride on Liu Jianfeng's face, Hu Jihong, who thought Liu Jianfeng was bragging at first, was a little uncertain now, and could not help but tentatively said: "This... Secretary Liu, your secret work Well done, I haven't heard you mention such a big good news before. Well, also, since your plane has already started test flight and certification, this engine...is it a bit late? "

"We haven't kept it secret," Liu Jianfeng said proudly, thinking of his boss's order to "brag and show off" before, "But maybe the aviation industry and the automobile industry are not closely related, and you Honda didn't notice much... …Speaking of which, the agricultural plant protection unmanned helicopter produced by our Huateng Industrial Group ranks first in the market share in Japan.”

Huateng Industrial Group's production of plant protection unmanned helicopters ranks first in the Japanese market? !
The news revealed by Liu Jianfeng made Hu Jihong even more unbelievable. Although he didn't know what the "plant protection unmanned helicopter for agricultural use" was, the meaning of "No. [-] market share in Dongying" was still very clear. Knowing this, he felt that it was extremely ridiculous: a product produced by a Chinese company can actually occupy the first place in the market segment in Japan? !
Bragging, right?

But at this moment, Hu Jihong still decided not to interrupt Liu Jianfeng, and listen to what he said next.

Liu Jianfeng did not disappoint Hu Jihong either, and continued: "As for the helicopter we are currently flying for certification, it is because during the process of plant protection operations, we found that the load of the unmanned helicopter is still too small, so after full investigation, We started this ultralight manned helicopter project.

This is a two-seater ultra-light helicopter with a maximum take-off weight of about 600 kg and can carry 100 liters of pesticides for plant protection operations, which greatly enhances operational efficiency.

In addition, in addition to agricultural plant protection operations, this helicopter can also be used as an entry-level trainer for helicopter teaching and training, just like the Robinson R22 helicopter and the TH-55 helicopter of the Millikin Army Aviation Corps.

As for why our aircraft has already started test flight, the engine is still here, because the helicopter we are currently testing uses the ROTAX914 engine of the Austrian ROTAX company, but after our engine has completed all the work of airworthiness certification, Our helicopters use our own engines! "

Only then did Hu Jihong suddenly realize: That's how it is!

Although he has never heard of the Robinson R22 helicopter or the TH-55 helicopter of the Army Air Corps of the United States, Hu Jihong has indeed followed Yamada Ichiro to the United States, and knows that there is indeed a piston-type aircraft engine in the United States. The two-seater ultralight helicopter is very cheap, and basically affluent middle-class families can afford it.

Thinking of this, Hu Jihong laughed secretly: It turns out that Huateng Industrial Group developed this kind of helicopter. I thought they were making that kind of large helicopter...

wrong!

At this moment, Hu Jihong suddenly realized: Since Huateng Industry can develop aviation-grade engines that are more sophisticated than ordinary civilian gasoline engines, why do they still develop F-series engines from Honda? !

There must be something wrong with this!
