Chapter 743: Skyrocket to 8,000 Meters!

Lu Yu got off the plane and retreated with all the leaders.

Song Kaifei began to control the helicopter into the sky.

Although the transport plane was huge, it was like a nimble bird at this time, without showing any clumsiness at all.

"It's so fast!" A staff officer exclaimed with wide eyes: "This is much faster than the previous take-off speed!"

"Hehe, good eyesight!"

Lu Yu smiled slightly: "This is the effect of the modified lightweight engine. The kinetic energy output is greater, so it will naturally be much faster."

Boom!

Just as the two of them were talking, the transport plane had already rapidly climbed into the sky.

Everyone looked up and saw that the volume of the helicopter was getting smaller and smaller in the field of vision, like an eagle soaring in the sky, slipped down and got into the clouds.

"It has risen to a height of 7,000 meters!"

The factory manager looked at the data from the nearby instrument and said in shock: "The helicopter with the best performance in the world can only reach a limit altitude of 6,500 meters! We have already surpassed the limit, and we can continue to break through. Hurry up!" It's eight thousand meters!"

Hearing this, everyone's faces showed expressions of surprise and surprise.

It's incredible!

It is already amazing that a helicopter can fly to such a high altitude.

Although most helicopters do not need to fly so high.

But this also represents the maturity and breakthrough of technology!

"Enough! Enough!"

Zhang Jinzhong said excitedly: "Let the plane come down quickly, if you fly again, something will happen."

The air at high altitude is thin, and the helicopter that only relies on the propeller to rotate has a limit value.

If you keep surpassing upwards and breaking through this limit, accidents will easily occur!

Lu Yu immediately took the walkie-talkie to give an order, and soon, the helicopter landed in the clouds and appeared in everyone's sight.

Everyone was shocked when they saw the helicopter.

Because, instead of landing slowly, the helicopter slammed into the ground rapidly at a vertical angle.

This shocked everyone.

The staff officer exclaimed: "What... what's going on? Is the helicopter out of control?"

Zhang Jinzhong asked anxiously: "What's the situation? Did the plane crash?!"

No one answered, and everyone's faces were ugly.

In the current situation, it is obvious that the power system of the helicopter has failed!

The factory manager's face was pale, and his eyes were full of despair.

It took a lot of effort to modify this helicopter, and it also devoted the efforts of everyone in the military factory.

Once something happened, wouldn't their efforts be wasted?

Now, everyone feels distressed as if they saw their own children have an accident.

"Why is this happening? Why is this happening! In the end...what happened?!"

The factory manager was about to go crazy and shouted anxiously.

Lu Yu looked very calm, and said with a smile: "Everyone, don't worry! Hasn't something happened yet? Just wait and see."

Everyone stared at him strangely.

The plane is clearly in free fall, are you blind? This is also called... nothing happened? !

When it really fell down and killed someone, it would be too late.

The guards beside Zhang Jinzhong hurriedly grabbed him and hid to a safe place.

When such a large plane falls, everyone present will be affected.

At this moment, everyone backed away in a panic.

Only Lu Yu stood there watching the helicopter fall as if nothing had happened.

When the helicopter fell to about 50 meters from the ground, the stagnant propeller started to rotate again.

The engine output a huge amount of kinetic energy, and the violent airflow rushed to the ground.

The people who were urgently evacuating were like wheat in a paddy field, tossed to and fro by the wind.

When the helicopter descended to only ten meters from the ground, it was stabilized again, and then flew again.

Song Kaifei took advantage of the situation to control the helicopter to fly around the playground, passing over everyone's heads, and triumphantly made a yes gesture.

Lu Yu just turned around, looked at Zhang Jinzhong and others who were stunned, and said with a smile: "I'm sorry, I performed a stunt for the leaders. It's nothing else, just to let you see how powerful this engine is. Cattle!"

Zhang Jinzhong and the others still hadn't recovered, feeling like they were dreaming.

Who would have thought of using a helicopter as a fighter jet?

After being stunned for a while, the factory manager breathed a sigh of relief, and a smile appeared on his face again: "It turned out to be a false alarm! Why didn't you say hello in advance when you performed stunts? You didn't scare me to death..."

As he said that, he patted his chest with lingering fear.

Zhang Jinzhong smiled wryly, wiped the sweat off his forehead and stared at Lu Yu: "You boy, you are so foolish! Next time, don't play tricks in front of me. If I don't have a heart attack, I'll scare you into sickness!"

The chief of staff was also not in a good mood and said angrily: "Dare, we were all worrying in vain just now, you boy, watching a good show is not a big deal!"

"It was originally a surprise for you. If I told you in advance, do you still have expectations?"

Lu Yu chuckled, and asked, "How is it? This plane is modified, right? It is made of special new materials and is not restricted by any environment or terrain. Even in the sea, it can fly as freely as on land. The Osprey helicopter boarded by Lao Mi will not lose the wind in the slightest."

"Good! Good!"

Zhang Jinzhong praised loudly: "The transformation is very good, you boy, you have never let me down."

After finishing speaking, he immediately called the factory manager to his side and ordered that the whole set of transformation plan must be kept in mind.

After these 20 aircraft have been remodeled, the helicopters of the entire army will be upgraded as a whole.

Zhang Jinzhong knew that, in fact, the cost of this kind of transformation is very small, only the cost of materials and labor is needed, but the result of the improvement is quite large.

It is completely equivalent to changing a brand new helicopter!

It's a good deal. Don't don't.

They continued to inspect with people, and then Zhang Jinzhong and others left for the air force.

The military factory continued to work overtime to improve, and Lu Yu personally supervised the work, giving detailed guidance and inspection to each helicopter.

Although the technology has been passed on, everyone still lacks experience after all.

Moreover, this kind of complicated engineering technology cannot become a master just by looking at one or two engine modifications.

If there is a problem in any of the links, a screw is in the wrong position, it may cause engine failure, and the machine will be destroyed.

In this regard, Lu Yu did not dare to neglect or relax in the slightest!

You have to firmly control it by yourself. Every modified helicopter has to go through his repeated inspections before it can be considered qualified.

In this way, half a month passed in a hurry in the busyness of everyone day and night.

Lu Yu finally managed to refit 20 helicopters before the exercise.

Among them, fifteen were directly delivered and five were used as spares.

After the completion of the last day, Lu Yu ordered An Ran to take the students back first.

And he himself took fifteen helicopters and went straight to the front line of the military exercise.
