After the crew skillfully installed a large propeller with a radius of 65 centimeters.

The big cow looked a little manic.

Instead of starting the bull immediately, the staff started to prepare first. The bull was fixed on a large steel plate, and its horns were fixed with screws on all sides.

Then a weight is placed on the steel plate.

Li Zhen was a little stunned: "It's so big, and its weight is at least two or three hundred kilograms. It is enough to fix it on a steel plate, is it necessary to add a heavy load? ”

Ma Jianbin said casually: "It is necessary, it is very necessary. Last time we also thought that it would be fine to have a bracket to fix it, but we were wrong. The power of the bull is far beyond my imagination. Especially after installing a large fan with a radius of 65 cm, it will cover the sky and the sun after it is activated, just like the end of the world. ”

Li Zhen smiled and sat in the distance: "Let's start." ”

Ma Jianbin stepped aside: "Let's start testing." ”

After speaking, a staff member hurriedly installed the last barbed wire fence behind the engine.

According to Ma Jianbin , the power of the bull was extremely terrifying, and the back was covered with barbed wire. Preventing it from sucking something behind it in, breaking the propeller is a trivial matter, and the most feared thing is to suck people over, which is a blood disaster.

With a staff member standing in front of him, a barrel of gasoline arrived.

I pressed the start button.

'Shh ’

A terrifying roar like a dragon's roar resounded throughout the mobile courtyard.

The inside of the engine suddenly worked. The air waves in the exhaust pipe rushed out wildly.

The engine is just starting to work inside, and the propellers haven't started spinning yet. The ground was already flying sand and rocks, and the exhaust air wave was too loud, blowing dust all over the sky.

The staff was at the console and began to slowly push the putter down.

Suddenly, the engine erupted with a 'buzzing' sound mixed with 'ang ang'. Deep, deep, yet extremely penetrating.

As soon as he heard this voice, Li Zhen sat up straight. If you analyze it from the sound alone, the power of this engine is terrifying.

The propellers began to spin.

'簌簌簌'

The entire courtyard was covered with dust, but after a few moments, it was all blown away.

The wind is gusting.

Li Zhen sat in the distance, on the side, and could feel the wind.

And the operator standing on the side is constantly rustling his clothes, and his eyes can't be opened.

The operator quickly pushes the actuator to the maximum, maximizing the power of the engine.

'Buzz'

In the thick sound of the engine, there was a shrill whistling. The speed of the propeller was already reversing, and the whole yard was filled with the roar of the engine and the terrifying sound of the wind.

Ma Jianbin made a gesture, and a staff member immediately put on protective gear.

Li Zhen frowned: "This is?" ”

"Give Master Li a visual demonstration of the power of the bull."

Li Zhen's eyes were full of doubts, and he watched the staff member wearing protective gear walk towards Da Niu head-on. Facing the propeller's vent.

At a distance of ten meters, the staff was a little unsteady, and the whole person was blown upside down by the wind. The clothes were blown up with a layer of waves.

Then the staff resisted the strong wind, pressed down and tried to move forward.

A few more steps forward. When he reached the position of seven or eight meters, the whole person's feet couldn't grasp the ground. The whole person was blown by the wind and slid backwards.

Lying on the ground with all his might, he crawled forward with his hands and feet, and he couldn't even get close to the propeller anymore.

The wind rode against him and stopped ten meters away. Recently, I walked to an eight-meter range, but after being blown back, I couldn't get into the 10-meter range anymore.

Li Zhen's eyes widened: "Is the power so great?" ”

Ma Jianbin nodded seriously: "Not only is the power high, but the propeller is also large." The air output is larger. It is no exaggeration to say that if a person stands in front of a propeller and starts the engine instantly, that person will be blown away. If you stand on the opposite side, it's over, you will be sucked in instantly, and then you will be beaten into minced meat by the propeller. ”

Liu Jinghong laughed: "Don't say such and that." ”

Ma Jianbin nodded very seriously: "I'm serious." Your aviation institute should pay attention to this problem, and in the future, you should add a safety net to the back of the aircraft propeller. At least when flying the plane, don't stop anyone in front of or behind. Otherwise, it is extremely easy to have a safety accident. You have to pay attention to this issue. 、”

"I know."

"Don't take it personally."

Liu Jinghong smiled and didn't say anything more.

Ma Jianbin looked at Li Zhen expectantly: "Master Li, how do you feel?" ”

Li Zhen stood up, asked the engine to be turned off, and then said, "Put it on the agenda as soon as possible." Time is running out, so let's make the test sample first and carry out a complete and strict actual test. Ask a professional pilot to find fault with all its problems and fix immediately where there are defects. Even hit back and re-developed. In a hurry, it had to complete its first test flight before July. All must be in place by September. Because at that time the pilots are going to start getting acquainted with this big guy, you have to be a little stressed, in a hurry. ”

Liu Jinghong and Ma Jianbin hurriedly stood up: "I know Master Li." ”

Li Zhen nodded and left, but he was extremely relieved in his heart.

A few years ago, people in this world didn't even believe that people could fly into the sky.

Today, a few years later, the Kyushu Academy of Sciences, which he created by himself, has been able to create a big guy with extremely terrifying power.

From the very beginning, it was just the development of the parachute.

Up to now, step by step research has been carried out on transport aircraft. The maximum load is 3 tons. The maximum capacity is 35 people.

Terrible transport planes.

If it continues to develop, it is not difficult for Li Zhen to imagine that one day, it will become a completely new means of transportation.

The dream of a blue sky, which human beings dare not imagine, will become the most ordinary means of transportation.

It will solve the problem of distance in this world. Bringing the world closer together.

Now it is carrying 35 people.

In the future, will there be transport aircraft of greater power capable of carrying one or two hundred people?

It's all unknown. But Li Zhen was full of great confidence, and he firmly believed that this day would come. ，

Driven by itself, the world's science has finally flourished and entered a stage of rapid development. This is the luck of the world, and it is also the luck of mankind.

Compared with their era as Zhang Zhi said, New Kyushu developed faster under the leadership of Li Zhen.

With the historical experience of that world, in the world history of the new calendar, the accumulation of 10,000 years of the era of cold weapons will now develop rapidly like a rocket.

Li Zhen took a deep breath and eased his mood, Laoshan was already stable.

Base camp, equipment, everything is ready.
