Chapter 753: Soaring up 8000 meters!

Chapter 743 Soaring up eight kilometers!
Lu Yu got off the plane and retreated with all the leaders.
Song Kaifei began to control the helicopter to take off.
Although the transport plane is huge, it is like a flexible bird at this time, without any clumsy feeling at all.
"So fast!" A staff officer exclaimed, his eyes widened: "This is much faster than the previous takeoff speed!"
"Hehe, your eyesight!"
Lu Yu smiled slightly: "This is the effect of the modified lightweight engine. With greater kinetic energy output, it will naturally be much faster."
Boom!
Just as the two of them were talking, the transport plane had quickly climbed to the sky.
Everyone looked up, the helicopter was getting smaller and smaller in the field of view, like an eagle soaring in the air, and it slipped into the clouds.
"It has risen to a height of seven kilometers!"
The director looked at the data uploaded by the instrument nearby, and said with a shocked expression: "The world's best helicopter can only reach a maximum altitude of 6,500 meters! We have exceeded the limit, and we can continue to break through. It's eight kilometers!"
Hearing that, everyone's faces showed surprise expressions.
It's incredible!
It is already amazing that the 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 with excitement: "Let the plane get off, fly again, but something will happen."
There is a limit value for a helicopter that only relies on propeller rotation because the air is thin at high altitude.
If you continue to surpass and break through this limit, accidents are very easy!
Lu Yu immediately took the walkie-talkie to give orders. Soon, the helicopter landed in the clouds and appeared in the eyes of everyone.
Everyone was shocked when they saw the helicopter.
Because the helicopter did not descend slowly, but slammed into the ground at a vertical angle.
This shocked everyone.
The staff officer exclaimed: "This...what's going on? Is the helicopter out of control?"
Zhang Jinzhong asked anxiously: "What's the situation? Has the plane crashed?!"
No one answered, and everyone's faces were ugly.
In the current situation, it is obvious that the helicopter power system is malfunctioning!
The factory manager's face was pale, his eyes filled with despair.
It took a lot of energy to modify this helicopter, and the efforts of everyone in the military factory were also devoted.
Once something goes wrong, wouldn't their efforts be in vain?
Now, everyone feels distressed like seeing an accident in their children.
"Why is this? Why is this! What the hell...what happened?!"
The factory director was going crazy and yelled anxiously.
Lu Yu looked very calm and smiled and said, "Don't worry, everyone! Isn't there anything wrong yet? Just take a look."
Everyone stared at him strangely.
The plane is clearly in free fall, are you blind? This is also called... nothing happened? !
When it really hits down and kills people, everything is too late.
The guards beside Zhang Jinzhong hurriedly held him to a safe place.
When such a large plane crashes down, everyone present will be affected.
At this moment, everyone panicked and backed away.
Only Lu Yu stood there watching the helicopter crash as if nothing happened.
When the helicopter fell to about 50 meters above the ground, the originally stagnant propellers rumbling again.
The engine outputs a huge kinetic energy, and a violent airflow rushes to the ground.
The people who are being evacuated in an emergency, like wheat in a rice field, were swept around by the wind.
When the helicopter descended to only ten meters above the ground, it was stabilized again and then flew again.
Song Kaifei took advantage of the situation and controlled the helicopter to fly around the playground, passing over everyone's heads, and making a triumphant gesture.
Lu Yu turned around and looked at Zhang Jinzhong and the others, who were stunned. He smiled and said, "I'm sorry, I performed a stunt for the leaders. No other meaning, just let you see how powerful this engine is. Cattle!"
Some of Zhang Jinzhong and others haven't recovered, and they feel like they are dreaming.
Who wants to use the helicopter as a fighter jet to drive and play?
After a long stun, the factory director was relieved heavily, and his face burst into a smile again: "It turned out to be a false alarm! Why didn't you say hello in advance when you performed stunts? Didn't scare me to death..."
After speaking, he patted his chest with lingering fears.
Zhang Jinzhong smiled bitterly, wiped the sweat from his forehead and stared at Lu Yu: "You kid, you're so crazy! Don't sell it in front of me next time, I will scare you out of illness if I don't have a heart attack!"
The chief of staff also didn't get angry and said: "Dare to love, we were all worried for nothing just now, you guys don't think it's too big to watch a good show!"
"I was supposed to give you a surprise, if you tell me in advance, do you still have a sense of expectation?"
Lu Yu smiled and asked, "How about? This aircraft can be modified! It uses all special new materials and is not restricted by any environment or terrain. Even at sea, it can fly as freely as on land~www. EbookFREE.me~Even if you run into Laomi’s Osprey helicopter, you won’t lose the wind."
"Good! Good!"
Zhang Jinzhong exclaimed in a loud voice: "It's been very well remodeled, you kid, I've never disappointed.
After speaking, immediately call the factory director to his side and order that the entire reform plan must be kept in mind.
After the transformation of these 20 aircraft is completed, the entire army's helicopters will be upgraded as a whole.
Zhang Jinzhong knows that, in fact, the cost of this kind of transformation is very small, and only material and labor costs need to be paid, but the result of the improvement is quite large.
It's totally equivalent to changing to a brand new helicopter!
Don't don't want it just cost-effective.
He led people to inspect for a while, 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. Each helicopter must be instructed and inspected in detail.
Although the technology is passed down, everyone still lacks experience.
Moreover, this kind of complicated engineering technology cannot become a master by just looking at one or two engine modifications.
If there is a problem in any one of the links, and a screw is in the wrong position, it may cause the engine to malfunction, and the aircraft may be destroyed.
In this regard, Lu Yu dare not neglect and slack in the slightest!
You must firmly control it yourself. Every modified helicopter must undergo repeated inspections before it is qualified.
In this way, half a month passed in a hurry in everyone's busy day and night.
Lu Yu finally hurried to the exercise before successfully refitting 20 helicopters.
Among them, fifteen were delivered directly, and the other five were used as spares.
After the completion of the last day, Lu Yu ordered the students to return first.
And he himself took 15 helicopters and went straight to the front line of the military exercise.
