Super Manufacturing Force

On the majestic mountain peaks, the wind is howling and whistling. When people stand on it, they will involuntarily have a sincere yearning for flying.

The two-wing jet pack can actually take off on flat ground, but taking off on flat ground is obviously much more difficult than gliding, and this is the first test flight, so Zhao Xu plans to start with the simple one.

He planned to use the jetpack to glide from the high mountains first, wait until he was in the air, and then start the power unit of the backpack to fly.

Suppressing the excitement in his heart, he manipulated the original energy to start manufacturing the jet backpack, and saw a metal backpack appear on the ground as the orange light surged.

The whole body of the backpack is bright silver, which looks beautiful and textured. On both sides of the backpack, there are a pair of folded wings. The hard feathers made of special lightweight fibers connected together are like layers of blades. The same, reflecting the dense cold light, although the wings have not been fully unfolded, but still can make people feel, a kind of majestic posture that wants to cut through the sky.

Between the wings, there are three power jets.

The secondary injection devices on both sides have one injection hole, and the main injection device in the middle has two injection holes. When you fly into the air, you will rely on these power injection devices to provide flight power for the backpack .

Zhao Xu made another skydiving suit and put it on. The skydiving suit has the functions of keeping warm, moisture-proof and waterproof. After all, it is very cold at an altitude of several thousand meters, and he doesn't want to be frozen into ice.

"Haha, it's finally starting!" Zhao Xu was so excited that every cell in his body was agitated.

He put on the helmet, put the jetpack behind his back, locked the chest and abdomen straps, and walked to the edge of the cliff.

Taking a deep breath, Zhao Xu clenched his fists tightly, kicked his feet hard on the ground, and jumped out with a snap.

The wind howled in his ears, and his figure fell rapidly. Zhao Xu howled: "Wow!"

The next moment, the huge wings spread out in an instant, and the strong air resistance supported Zhao Xu to draw an arc in the air, flying out far away like a hang glider.

The delta hang glider uses the joystick to change the center of gravity of the body to achieve the purpose of changing the flight direction, while the biplane jetpack, in addition to using the center of gravity, mainly changes the direction of air flow by changing the angle of the wings, and then changes the flight direction.

"Haha!" Zhao Xu shouted excitedly, and immediately clenched the handles of his wings.

I saw his arms exerting strength, two pairs of huge wings tilted to the right, and the whole person immediately turned around in the air, like a big bird, drew an arc and flew directly to the right.

"Haha, I'm a little bird. If I want to fly, I can fly high..." Zhao Xu grinned, not caring about the strong wind, and poured it into his mouth.

After sliding for a while, he was about to try to activate the power injection device: "Hey, it's time to try real flying!"

He spread his wings evenly, and as orange-red flames spewed out from the four nozzles, a strong force suddenly pushed him forward, making him speed up to the extreme like a bullet being fired: "Boom!"

The clouds flew by quickly, and the speed of the wind made Zhao Xu's blood boil. This feeling was really refreshing.

A flock of wild geese suddenly appeared in front of the left, and Zhao Xu laughed "haha": "Birds, look at my brother, I will catch up with you!"

His arms were thrown back, his wings were slightly retracted, and the next moment,

The whole person is like a fighter jet, whizzing through the wild geese, and dozens of wild geese flew around in panic.

"Hey, come again!" Zhao Xu turned around with a smirk, ready to tease the poor wild goose again.

However, his flying speed was so fast that he was actually in the air, drawing a huge arc with a diameter of no less than a kilometer before completing the turn.

When he turned around, he was actually thousands of meters away from the group of wild geese.

This is like driving. If the speed of the car is fast, let alone a sharp turn, the entire body must pass through a huge arc before it can successfully change direction. Otherwise, the huge inertia brought by the high speed will make the car roll over directly. .

Zhao Xu was covered in cold sweat. He suddenly realized a problem. The turn just now was in the open sky, so he couldn't see anything.

But imagine, if it is in a city full of tall buildings? I'm afraid that with just that one hit, he definitely hit the building.

"It seems that manipulating the wings with only two arms is not dexterous enough. If we want to fly at low altitude in the city in the future, we must solve this problem first!" Zhao Xu thought to himself.

In the evening, while Zhao Xu was eating in the hotel, he was thinking about how to solve the dexterous steering problem. Suddenly Zhou Hongtao called and asked him for help.

Helpless, he could only temporarily stop his research and drive back to Dongjiang City the next day.

"Hey, Hong Tao, I'm back to Dongjiang, what's the matter with you, and you didn't tell me when I asked you on the phone?"

"You're back? Great, stay at home, I'll go find you right away!" Zhou Hongtao yelled in surprise, and hung up the phone in a hurry.

"You're in such a hurry, what's the matter?" Zhao Xu wondered.

Twenty minutes later, Zhou Hongtao arrived like the wind, entered the door and sat down on the sofa: "Brother, you miss me so much, I thought you played too much and didn't want to come back!"

"No price, you're not a beautiful woman, don't be nasty with me!" Zhao Xu rolled his eyes: "Hurry up and talk about something, aren't you in a hurry!"

"Yes, yes, the business is important!" Zhou Hongtao immediately sat up straight: "Brother, my dad got an ultra-precision high-speed milling machining center from Japan some time ago, and the machining accuracy can reach 0.001 microns, which is nanometers. Class ultra-precision machine tools!"

Zhao Xu was surprised when he heard this. After contacting Zhou Hongtao some time ago and reading some mechanical books, he also had some understanding of the current machine tool industry.

Although the domestic machine tool industry has developed rapidly in recent years, the high-end machine tools are still far behind the international ones, especially the nano-scale ultra-precision machine tools.

Machining and cutting, to put it bluntly, is to use relatively hard metals to cut relatively soft metals. Of course, this "soft" is relative.

Think about it, how much force does it take to cut a piece of iron?

This is not cutting vegetables, just cut them with a kitchen knife!

The power in this is unimaginable. Such a large force will definitely vibrate all machine tool components including the tool and the spindle.

And the vibration will affect the machining accuracy of the machine tool. This is like our usual writing. If someone keeps shaking the table, who can write a beautiful text?

Of course, vibration is only one aspect. There are other factors such as the material properties of the manufacturing tool and the spindle, the horsepower of the motor, and the stability of the cooperation of various parts of the machine tool. These are all factors that affect the machining accuracy of the machine tool.

Therefore, it is even more difficult to improve the accuracy of machine tools.

Now in China, only some cutting-edge experimental bases have nano-scale ultra-precision machine tools, such as the aerospace technology industry controlled by the government.

At the same time, due to the international technology blockade against China, it has resulted in the fact that in China, it is rare for the people to see ultra-precision machine tools at the nanometer level.

But now that Zhou Hongtao's father has actually obtained such a machine tool, it can be regarded as a supernatural power.
