Those who have experience in many countries also reported in Laoshan the next day.

In the Kyushu Academy of Sciences, these people who are about to participate in major missions have temporarily lost their freedom, and in order to prevent the news from being released in advance and causing bad effects, they also voluntarily stay in the Kyushu Academy of Sciences and do not go out for the time being.

A larger auditorium was carved out for them, and then all the personnel began to learn.

They talked to each other.

From world geography knowledge classes to air emergency evacuation classes. and then to some wilderness survival skills.

What can be thought of and taught to them, the Kyushu Academy of Sciences has no reservations.

This will be the world's first air expeditionary force, and each of them will have a very great responsibility on their shoulders.

And those translators also communicated with each other, and exchanged ideas.

If you will be in the country of black chickens, he will not.

Then you teach him to speak the words of the black chicken country, and he teaches you to learn the words you don't know.

These translators are highly gifted with languages and work very hard to learn. They are determined to learn as many foreign languages as possible before they set off.

Even if it's not so neat, at least some keywords must be learned.

The Air Force, on the other hand, has to learn more or less every subject, and the most important thing is radio technology. To become an Air Force, you must know radio technology and communicate with ground crews at any time. However, what they have to learn now is the maintenance techniques of radio transmitters. Thorough understanding of the principle.

Everything has to be ready.

Li Zhen came to the Aviation Academy and began to investigate the research and development of large aircraft.

Liu Jinghong said: "In the vision, we need an aircraft with a large load, strong durability and stability. Maybe it doesn't need to be too fast, but be sure to be safe. “

Li Zhen said: "I'll take a look at the drawings." ”

The staff brought the drawings that were temporarily confidential, and Li Zhen looked at them for a moment.

It was discovered that this plane was an enlarged version of the Grasshopper, and it looked similar, with double wings.

But one thing is different is that this enlarged version of the Grasshopper is twin-engine.

Having learned the lesson of the failure of placing the engines on the left and right wings, this time the Aviation Institute made a breakthrough.

They were able to think of putting both engines in the nose.

It's a breakthrough in thinking.

Although the two-wing power is abandoned. However, a double-headed aircraft was developed.

Liu Jinghong introduced on the side: "This large aircraft, we tentatively named 'Peng' has the meaning of Kunpeng, sailing thousands of miles away, huge and infinite. ”

Li Zhen nodded, carefully looking at some details of the design.

Liu Jinghong said proudly on the side: "The Peng aircraft was conceived by me, and it is successful in theory, but it needs to be operated in practice. Its twin nose will place two twin rows of nine-cylinder star engines. The momentum will be more surging than ever. Originally, it was planned that one engine in the nose would be used as the front power, and one engine in the tail would be used as the rear power. But I vetoed it, and I felt it wasn't going to work. So the double nose was made. ”

"The two engines are lined up neatly, with a distance of 1.5 meters between the engines. Both engines are equipped with propellers, and the interval between the twin propellers rotating is 0.2 meters. will provide double the power. ”

"It is theoretically expected that the dead weight of the finished Peng aircraft will reach 2.1 tons. The maximum load-bearing limit of the Peng aircraft is 3 tons. Based on the average size of a normal adult, the Peng aircraft can carry up to 35 people. ”

Hiss –

Li Zhen gasped, taken aback by this number.

Can fly a 35-person plane?

Liu Jinghong said with a serious face: "I know it's hard to believe, but in fact it's true. It's all too likely to succeed. ”

Li Zhen groaned: "With such a huge fuselage, will its speed be much slower?" ”

"It looks bulky, but it's not slow at all. Theoretically, it can still reach a cruising speed of 220 km/h when fully loaded. ”

"So fast?"

"Of course, because it's about to be a breakthrough design. Twin heads. Double-row, nine-cylinder, ultra-high-power radial engine. ”

"This kind of high-power engine is very challenging for the rotor to bear. ...... over there in the mobile yard"

Li Zhen didn't finish speaking, and Liu Jinghong said confidently: "We were originally going to use a double-row seven-cylinder engine. But it was the Mobile Institute that suggested that we use a double-row nine-cylinder star engine. They are confident in the twin-row, nine-cylinder engine. What they are looking for is that kind of strength and beauty. ”

"I'll take a look at the engine first."

"Then I'll take Master Li to the Mobile Courtyard."

“……”

For the design of the aircraft, Li Zhen did not have too many worries. The design and development of the Aviation Research Institute is still very reliable, but every time it will be stranded because of engine problems. Of course, outsiders don't know this, outsiders only know that the mistakes are all in the Aviation Institute, but in fact, they are not, the mistakes are not in the Aviation Institute. Strictly speaking, it is not a mobile hospital, but the current industrial level limits the power system.

Ma Jianbin from the mobile institute personally greeted him, and when he heard that Li Zhen wanted to see the double-row nine-cylinder star engine, he was very excited: "Hurry, go and move our 'big cow' out." ”

turned around and said to Li Zhen: "Master Li, I am very confident in the double-row nine-cylinder engine. Although the cycle is short, the technology is very mature, it is not only terrifying in power, but most importantly very stable. I know that for long-haul flights, stability and safety must come first. There is no need to worry about this, when we experimented before, the 'Big Cow' continued to work for three days and three nights under the supply of fuel, and it was still full of power. There was no damage. After working for so long, the engine is red inside and out, but it's still as strong as new.

If it wasn't blown, the engine was hot enough to cook a piece of raw meat in a few seconds. But it still works. We wanted to find its limits, but we didn't find it yet. ”

Li Zhen asked, "Working continuously for three days and three nights?" What about abrasion?"

"Haha, the reason why I am so confident is because of the material. A metal researched by the Institute of Materials Engineering has extremely strong heat resistance and wear resistance. In addition to being a little heavier than steel, it has an extremely high melting point and a terrible degree of sturdiness. So the wear and tear consumption is weak. ”

Soon, the people of the mobile courtyard moved the legendary 'big cow' out.

It is said that it is a big cow, but it is indeed big.

This engine has a neat shape. It's almost as simple as a table of eight immortals. From a distance, even if it hasn't started yet, it gives people a strong psychological pressure and a sense of shock that comes out of the bones.

Li Zhen's eyes lit up, and he could only think of one word in his heart - the beauty of strength.
