78First flight

After careful preparation, Cao Yu finally decided to fly to the Principality of Meijian and personally negotiate arms trade with the other party.

I can't wait any longer. Chuzhou's finances are basically going to bottom out. The city lord's mansion has almost used up all the savings before, and the money I got from Yunzhou is almost bottom out.

Infrastructure is really too expensive, so the arms trade must be started as soon as possible, otherwise you will starve to death.

Cao Yu came down to the airport with his group.

In fact, it is better to say it is an airport than a runway. It has just been built. Other buildings are still laid foundations. There is not even a building next to it. There is only a shack, which is the temporary residence of construction workers.

The planes were parked at the end of the runway, with a total of three.

Cao Yu was not busy boarding the plane, but looked around the plane a few times, first, then tapped it with his fingers, and sometimes he also talked to the pilot and asked questions.

He was worried that the plane would not be safe, and he was afraid that the plane would fall down as soon as it flew into the sky, so he asked around.

To be honest, if he could, he really didn't want to ride this plane at all. It looked like it was made of paper and was very unsolid. There was no all-metal plane in this world.

On Earth, the world's first all-metal aircraft - f13    The passenger aircraft was designed and developed by German aircraft designer Hu Guo Junckers, who started the all-metal era of aircraft.

Before the 20th century, it was the mainstream that aircraft adopt wooden structures.

In 1903, the world's first aircraft developed by the Wright brothers was made of wood. The body consisted of skeletons, pillars and ribs were made of spruce wood, propellers were made of walnut wood, wing skins were made of linen, and only a few load-bearing parts were made of metal rods.

Wooden aircraft have light weight, easy processing, and low cost. Early aircraft engines have low power and low flight speed, so the load on the wing surface is also small, and the strength of the wooden material can meet the needs. However, the disadvantages of wood materials are also obvious: low strength, low stiffness, flammable, easy to corrode, and strong hygroscopicity.

This plane is not an all-metal plane, so no wonder Cao Yu was frightened.

But the pilot was full of confidence.

While Cao Yu was observing and studying around the plane, Kong Jun stood on the other side.

He didn't follow him. He had seen planes a long time ago, and had also taken many planes. He had long lost curiosity and interest in planes.

Seeing Cao Yu looking around the plane, he couldn't help but ask Mei Zi next to him: "Miss Mei Zi, has the Grand Marshal always been like this? He is very interested in everything?"

He thought Cao Yu had never seen a plane.

Mei Zi smiled and said, "Does Mr. Kong think that the Grandmaster has never seen a plane?"

Kong Jun was stunned and turned his head to look at Meizi. Isn’t it?

Meizi looked at Cao Yu in front of her and said, "Although the Grand Marshal did not say it clearly, I know that the Grand Marshal must have taken a plane, and there are many, and the kind of plane the Grand Marshal has taken is a hundred times better than this one."

"A hundred times better than this plane?" Kong Jun was stunned at first when he heard this, and in an instant, his pupils suddenly shrank.

One hundred times is definitely an exaggeration, if you correct it, it may be ten times!

But the problem is that only one airline is manufactured by one airline in this world that is ten times better than the one in front of you. But the problem is that those aircraft are specially customized for some people. Ordinary people don’t have the qualifications to even want to sit. Is it a great coach...

He looked at Mei Zi in surprise.

Unfortunately, Meizi didn't look at him, and Meizi's eyes kept following Cao Yu.

"Mr. Kong, the Grand Marshal is now studying this plane so seriously, and there is only one purpose, that is, while observing other people's planes, thinking in his mind, thinking about how we can make better than this one when we build our own planes in the future!"

"What do you mean is that the Grandmaster still knows how to build planes?" Kong Jun was completely messy.

Although he had talked with Cao Yu for a long time before, most of them were concentrated in the humanities and social fields, and the science and engineering were only discussed in general and did not go deeper, because he didn't understand it either. But now, the woman closest to Dashuai told him that Dashuai actually knew how to build planes!

this?

It's true and fake!

Mei Zi smiled: "Although the Grand Marshal didn't say it clearly, my intuition tells me that the Grand Marshal must also know how to build airplanes."

"Intuition?" Kong Jun was stunned.

"Mr. Kong, don't underestimate women's intuition. Women's intuition has always been very accurate. Dashua once said one thing, never doubt women's intuition."

"..." Kong Jun didn't know how to answer.

Meizi smiled and said, "Mr. Kong doesn't know yet. All the weapons of our Tiger Regiment were designed by Dashang alone?"

"Ah?" Kong Jun opened his mouth wide.

"Mr. Kong will be no longer surprised. Let's go. The coach has finished watching. It's time for us to board the plane."

The group started boarding the plane.

Cao Yu sat behind the pilot.

In this way, once the pilot has any abnormalities, he can discover and take action as soon as possible.

His concerns mainly come from two types. One is that he is worried that the pilot will not be able to deal with the special weather. The second is that he is worried that the Principality of Mikashi is secretly engaged in conspiracy, so he sits behind the pilot and can deal with it in time if any abnormality occurs to the pilot.

Kong Jun was going to sit behind, but saw Cao Yu sitting behind the pilot, so he sat down next to Cao Yu.

"How does Dasang think of this plane?" He asked casually.

"It's not so good. Put a few stools in a shell. What kind of airplane is this? When our Chuzhou has its own aircraft factory in the future, we will build our own aircraft more than ten times better than this one."

It's ten times indeed!

Kong Jun said secretly.

"Master, if we built the plane ourselves, how should we build it?" Kong Jun asked again quickly.

"If it was my design, I would use the aluminum all-metal passenger aircraft method. The length is about 9.6 meters, the wingspan is 17.75 meters, the take-off weight is 1730 kilograms, which can carry 4 passengers, two pilots, the cruise speed is 140 kilometers per hour, and can fly for 8 hours. The wings are made of 9       The root spar, which is made of metal aluminum, the fuselage is a structural structure, and the outside is covered with corrugated aluminum skin."

Cao Yu said slowly. What he said was actually the first all-metal plane on Earth, the Junx F13, so all the data was readily available, and the relevant design of the aircraft was clear, but Kong Jun didn't know this. After hearing this, his pupils suddenly shrank.

really!

The Grand Marshal is indeed of great origin. Isn’t the kind of plane he mentioned?

Hahahaha, I, Kong Lao Er, have really had a great fortune and actually defected to such a big shot!

After coming to his senses, Kong Jun wished he could laugh three times.
Chapter completed!
