Li Zhen didn't pay attention to what others said.

But to be honest, hearing the discussion of those onlookers, I still feel a little ridiculous.

Liu Jinghong had already smiled and leaned back: "It's a serious pretend." The hydrogen tank is in the wings, hahaha, laughing to death. ”

Xu Xiufeng's face was flat, and he said, "Dean Liu doesn't have to veto others like this." Science, who doesn't cross the river by feeling the stones? Just make bold assumptions and be careful to verify them. Isn't every scientific progress the crystallization of whimsy? Maybe thousands of years later, our descendants will see this part of our history and laugh at us like fools. ”

Liu Jinghong was confused: "What do you mean?" Why do future generations laugh at us like fools? ”

Xu Xiufeng smiled: "The scientific level is not equal, and the concept is not equal." It's like when we laughed at Xun Jiayuan's whimsical ideas and vainly tried to invent a spaceship. ”

Liu Jinghong laughed and said, "If you don't say it, I almost forgot." That old man Xun is indeed absurd......"

Xu Xiufeng said with a straight face: "I didn't mean that. Ignore Xun Jiayuan's identity for the time being. From a scientific point of view, spacecraft are not without the possibility of realization. Hey, it's getting darker and darker. For example, it was like a long time ago, when they all laughed at us for inventing a paraglider, and everybody thought we were ridiculous. But in the end we succeeded. ”

Xu Xiufeng's ability to articulate and express himself is not clear enough.

But Li Zhen still heard the taste, and couldn't help but look at Xu Xiufeng with admiration. I hadn't noticed that Xu Xiufeng still had such a state of thought.

I can't help but recall that before he joined the Kyushu Academy of Sciences, he was a senior teacher at the Imperial College transferred by the imperial court, and at that time, wasn't he just a mockery of the Kyushu Academy of Sciences?

Liu Jinghong and Xu Xiufeng chatted. And Li Zhen looked at the blue sky and white clouds outside through the car window, and couldn't help but think of that sentence again:

The wind is blowing, and the only way to survive is to try to survive.

He now remembered who told him this sentence, it was Zhang Zhi who told him.

A sentence that is difficult to understand needs to be chewed and swallowed slowly, and it needs to be tasted carefully, and it needs to be tasted repeatedly and reversed.

In a different scenario, the meaning of this sentence will seem a little different.

The original words are: the wind is rising, and the only way to survive is to try to survive.

Li Zhen lay comfortably on the soft sofa, blowing the majesty under the blue sky and white clouds coming from the car window, reached out to pick up the hair that covered his eyes, and muttered in a satisfied and firm tone:

"Everyone can't help themselves, and they are caught up in a hurricane that I know is delusional, and what I can do is no longer bury my dreams and face reality. It's just trying to live, live, live, no longer die, and find and hold on in the wind that can't be seen and resisted. ”

“……”

An hour later, we came to a spacious, flat sandy and gravel floor on the Great Wind Terrace.

Li Zhen and the others jumped out of the steam car and saw that the onlookers had consciously stood behind to make way for space. And the crew is unleashing the tow on the plane.

Liu Jinghong was nervous, not just Liu Jinghong. Everyone in the entire aviation institute was nervous. Because this is a test flight in the true sense of the word.

It was an experiment in which there was no certainty at all, no practical support, and even very weak theoretical support.

Li Zhen didn't plan to enlighten them.

Maybe their growth is too smooth, every time it's a success, a success, a success. Didn't suffer any blows. Every progress has been made with a large number of basic theories provided by itself.

This time, even he had no way to offer them. It is completely necessary to cross the river by feeling the stones.

If they succeed, they will do it from the heart.

If they fail, then they will be more determined.

Li Zhen personally went to inspect the aircraft, from the triangular landing wheels of the aircraft, to the balance of the wings, to the safety hazards of the stability of the fuselage. From beginning to end, we don't let go of a single bit.

If the experiment fails, it may not fly into the sky at all. There are no safety hazards either.

If the experiment is successful, then it will be fraught with certain dangers.

Li Zhen asked, "Which one to try first?" ”

Everyone looked at each other, and Liu Jinghong shouted: "Then try the one-winged one first, right?" ”

Li Zhen waved his hand, and the staff immediately took off the one-wing plane and hung it on the tail of the two steam cars with ropes.

It's not realistic to use horses to pull it, and one steam car is obviously not powerful enough, so let's use two.

Of course, two cars come to pull, then the force will be dispersed.

It only starts with two cars, and when it runs completely, it breaks the rope towing of one of the cars.

When everything was ready, Liu Jinghong volunteered to jump on it and laughed: "This is the plane I designed." I'm going to do it myself, its first test. ”

Li Zhen frowned, wanting to say something, but his tone changed: "Fasten your seat belt, wear a safety helmet, don't be thrown out." ”

Liu Jinghong nodded while making safety facilities: "No." I have a lot of confidence in it, and I said, the monowing is the king, and the monowing must be the king. There's my soul here, and I'm familiar with it. ”

Li Zhen rolled his eyes and pointed to the vast beach in front of him: "The distance in a straight line is five kilometers." If you can't fly five kilometers, then it proves to be a failure. ”

Liu Jinghong took a deep breath: "I promise that it will definitely take off within five kilometers." ”

“……”

After making arrangements, it was the students of the two aviation institutes who drove the steam car. After they had done a good discussion, there was no nonsense and they started the car.

By this time, the onlookers had all run to the front, standing on both sides of the road.

Many people from the Kyushu Academy of Sciences also ran to the front, ready to record data at all times. And on the five-kilometer flat road, the distance is also drawn with white lime, one every two hundred meters. In this way, it is possible to know the data at what speed and at how many kilometers the plane can take off.

When everything was ready, the steam car whistled. The 'woo' is endless.

Li Zhen waved his hand.

They got the signal, and the two steam cars started at once.

At the beginning, it was the maximum speed, but the plane, which was several hundred kilograms, was moving slowly and heavily.

Seeing this speed of movement, Li Zhen couldn't help frowning, and muttered, "Is it still too heavy?" ”

The crowd of onlookers in the distance was also discussing:

"How can this fly?"

"This is the flying machine? Isn't this a kite? ”

"Does their new aircraft have to be pulled by a car from below? But what's the point? 、”

"Alas, this is really a failed science. It is necessary to use external forces to fly into the sky. ”

"Is it to pull it up with a car and then cut the rope. The main thing is to complete the gliding, huh? It doesn't make any sense. ”

“……”

Outsiders don't understand.

They simply did not understand what the point of this unpowered test flight was.

'Woo woo'

The steam whistled.

In the white smoke, two steam wagons dragged the monoplane from slow to fast, and finally ran at a speed of twenty kilometers per hour.
