Yonglong eight years.

Summer.

Li Zhong began to study the engines of airplanes with craftsmen in Liaodong.

In fact......

Clever ancients already knew that in order for an airplane to take to the skies, the engine had to be light and powerful.

The original steam technology was used on trains, but it was not a big problem.

But if it's copied and used on an airplane, it's a bit worse.

This time......

What they were going to design was a gasoline engine.

And because they have already used the original steam technology to optimize this countless times.

Therefore......

Even if it is changed to gasoline this time, it feels like it is still a light car.

It took about half a year, that is, at the end of the eighth year of Wing Lung to finally develop the first gasoline engine with real practicality.

】

After some testing by craftsmen and Li Chong.

The engine is stronger than the original steam engine, both in weight and in power.

Thereupon......

By the end of the year, Li Zhong and others also installed the engine on a wooden plane that had been made in advance.

On the plane, with the exception of the frame and landing gear, which are made of steel, almost everything else is made of wood.

And then......

On a sunny day without heavy snowfall, the wooden plane took a test flight.

All I can say is......

Even the thrust-to-weight ratio of this gasoline engine has been increased by many times compared to that of a steam engine.

But!

If you want to say whether it can really fly, this Li Zhong really doesn't dare to say.

If Li Chong had to figure out whether it could fly.

Then you have to grasp what Bernoulli's equation is.

And such a high-end thing, Li Chong is naturally impossible to master.

That can only be empirical.

Fortunately......

Liaodong has enough experience in this area, and even, so to speak, they have almost thirty or forty years of experience.

This undoubtedly provides a very strong guarantee for the success of this test flight.

And just before this test flight, Li Chong also asked people to study the parachute.

After all......

No matter how you say it.

If you really fly, if something breaks down in the sky, there is no way to survive.

Soon......

The sound of the engine sounded.

The huge propeller in front of the plane also rotated at high speed.

With this high-speed rotation, the plane also slowly ran on the track little by little, under the control of the pilot.

The person who tested the pilot was one of the young craftsmen from Liaodong.

And......

It seems that only young people can take on this kind of test flight activity.

The old man may fall from the world once and the person will be gone, and if this young man is a young man, maybe he can be rescued again.

In the eyes of everyone's expectation, and in the excitement.

Finally......

These people have been studying the plane for thirty or forty years, and this time it really flew off the ground.

This moment!

Everyone was so excited that they didn't know what to say.

Li Chong also looked at this small plane, which may be less than two feet long.

For a while, I couldn't help but sigh infinitely.

said: "Small is a little small, but it's good to fly." ”

"From now on...... What needs to be solved is battery life, safety and reliability. ”

After all......

It's one thing to invent this, but it's another thing whether it will catch fire like Tesla and other trams.

Zhang Sui and Li Shi were also brought by Li Chong to visit the test flight.

All I can say is......

Although theoretically, they all know that it is possible for the plane to fly.

But!

When you actually see it flying, and it's still able to make all sorts of movements, it's a different feeling.

Zhang Sui: "It's really flying." ”

Li Shize: "......"

Then, without waiting for Li Shize to say anything, the craftsmen over there hugged each other excitedly.

Shouted: "Success! It really worked! ”

Li Zhong looked at it, as if they were like Fan Zhongjin.

It wasn't until a long time later that they discovered that Li Chong, Zhang Sui, and Li Shize were very determined.

Only then did he slightly retract his previous indecent demeanor.

walked over, came to Li Chong's side, and respectfully saluted Li Chong.

All I can say is......

He is worthy of being the founder of the Academy of Sciences!

The problems that they couldn't solve no matter how they tried to solve them before, but in the hands of the other party, they were solved all at once.

"Elder Li!"

"Please bow down to me!"

The other party saluted Li Zhong with a serious face.

Li Chong was very determined.

Just replied: "Next, there is still a long way to go, although it looks successful now, but we can't slack off in the future, we must continue to improve, and we must strive for excellence." ”

For example, if you want to make a large transport plane, then Datang can carry out long-distance soldier delivery, and even send food and materials to the battlefield.

Of course!

If Li Chong is not mistaken, it seems that even in later generations, there are only a few countries in the world that have the ability to produce large transport aircraft.

But......

This path can be taken step by step.

Next......

That is, to report this matter to Li Xiang.

Li Chong asked Li Shi, who came to see the play, to enter the palace to inform Li Xiang.

The next day, the court meeting.

Li Shi said this.

A sentence is that the plane takes people to the sky.

It also made the Manchu courtiers feel a sensation.

In addition, Li Shi described it like a bird, flying freely.

This time, Li Xiang couldn't help but be a little curious.

In fact, Li Xiang is not averse to new technologies.

But......

He is also Your Majesty, and you have to inform him when you do something.

This is the minimum respect for him.

Li Xiangdang even asked the prince and the prince when it was convenient for him to take a look at it in a consultative tone.

Afterwards......

Li Shi gave him two choices, one was to take off from the suburbs and fly over Luoyang, and the other was to watch directly from the suburbs.

What is the difference between these two different ways of viewing?

The first way is conducive to helping Tang Guowei.

The second approach might be a little better in terms of secrecy.

Li Xiang didn't quite understand what this meant for a while.

It stands to reason that such science and technology should be kept secret.

But then Li Shi said, "I think the first way is better." ”

Li Xiang asked, "Why?" ”

Li Chong: "This can better reflect that Your Majesty is the destiny of heaven." This is hidden, and it seems to be a little too petty. Other than that...... Aya also said that this is also of great help in enhancing the self-confidence of any nation. ”

Although Li Xiang didn't quite understand what this national self-confidence meant.

But......

He heard what Li Shize said was too petty.

In that case, let's fly over Luoyang.

Celebrate with the people!
