Monster Factory

Who's ever been treated like that?

Cold and surrounded by dozens of strong men in black, these mechanics and pilots filled their faces with inquiry expressions similar to those of the Internet.

The object of exploration is naturally the main skeletal constant leisure.

Chang Yu was also stunned, he had not encountered such a scene in his life.

“Why… why?” Two professors from Tianfu City Flight College hesitated to speak out and the space aviation profession gave them access to similar confidentiality agreements in the past. But when that kind of agreement was signed, it was clear that dozens of strong men were not around.

“Because you are about to visit a production site that can change the future of aviation, and because this is commercial cooperation, we must eliminate the possibility of early leakage.” Metal experts still have no expression on their faces, which makes them more busy than old captains in spy TV shows.

Chang Yu Le did not say anything, and signed his own name directly on the confidentiality agreement.

Instead of giving him any mustard, this treatment filled his heart with unspeakable surprises.

The main bones are penned, and the rest of these people naturally cannot remain indifferent. However, they looked over and over again at the confidentiality agreement. Finally, both of them and Tianfu Aeronautical Industry Group had collaborative professors on the subject. They continued to defame the company that there was nothing wrong with it.

Changing the future of aviation?

Even Tianfu Aeronautical Industry Group, which designed Huaxia's first invisible warplane, dared not say that. At best, they dare to say that they are striving to catch up with the footsteps of developed countries and become the leading international aviation industry group in the next decade.

After twenty minutes of tossing, this legendary factory is finally open to Changyule travelers. They took two dedicated electric sightseeing cars and drilled into the factory like fish into a pond.

All whispers and suspicions, after they went in, were gone.

It's like walking into a giant factory, a six-person tourist electric car, untouchable even on the edge of the pedestal in front of an elaborate aircraft production line. Two sophisticated aircraft frames made of alloy are on one end of the production line and are now just for visitors.

But at first glance, you realize that when this line finally comes to fruition, huge and strange aircraft like the line factory can be produced from time to time.

When the tourist car walked to hundreds of magically modified five-axis processing centers, the two professors of space had no other emotions than to try to breathe. Their belly defamation in front of the door has been completely smashed by everything in front of them.

Is it a fully mechanized assembly plan?

Manually assembled whenever manned, whether small or large aircraft are produced.

The main reason for the manual assembly, apart from the inability to guarantee accuracy with automatic manipulators because of the complex mechanical components involved, is related to the high use of lightweight composites in modern aircraft.

Lightweight composites have the strength, weight and lightness advantages, and who can apply more lightweight materials on a weight-loss precision to grams of aircraft means winning economically. But lightweight composites have many insurmountable problems, such as having difficulty welding.

Different melting points of different metallic materials weld the two materials together, and their welds become quite fragile. If you use it in an aircraft, the vibrations generated by flight alone can disintegrate the vehicle.

Even when aware of this, lightweight composites are either monobloc or riveted. The breakdown of the aerial distress caused by the breakdown of the structure of a part of the aircraft still leads to a large amount of blood and tragic lessons.

The process of assembling an aircraft is so demanding that each assembler needs a special torque wrench with a counting function to collect the number of turns of a screw on it.

The degree of tension of all screws is consistent, allowing the vehicle to avoid local structural anomalies caused by resonance in the event of flight.

In front of this production line, this assembly scheme is completely broken. Whether it's hundreds of five-axis machining centers or fully automated robots all over the production line, they don't need assemblers, they just need machines.

At the end of the line are two gantry welding centers like the mountains.

The height of the welding center exceeds twenty meters, and from the diameter of the workbench and the sliding tracks all over below, it is easy for the two professors to guess that the two gantry welding centers are the last steps to complete the installation of the aircraft.

This process is called riveting skins in traditional production.

Stud connections are used for all aircraft casings, as the aircraft skins are all sheet aluminum and this material is simply not weldable. In addition, welding results in varying structural strength and defects such as welding residual stress deformation.

When the aircraft is flying at high speeds, the body vibrates very strongly, using welded skins, and it is likely that a piece of skins with welding defects will be ripped off and then, like a piece of torn paper, the tear openings will expand rapidly.

“Are you going to use welding to install the skins?” The two professors' eyebrows keep shaking, "or the automatic welding process? ”

“Is there a problem? Any aircraft is subjected to structural static testing, and we dare to design it this way, naturally passing the test with certainty.” Ye Qing certainly understood the thoughts of the two professors. They must think the giant animal industry is crazy.

But technology is used to break it. The existence of the rivet process does not prove that it is stronger than the welding process. Only limited by materials and body design techniques, engineers can only use rivets.

With more than 100,000 skinned rivets on a passenger fuselage, the rivet is an extra load and uses welding technology, which naturally saves a lot of self-weight.

The professors muttered several times and, finally, found no reason to refute them.

Because they haven't seen the crafty aircraft, and the equipment in front of them is unknown. If you don't think about it, where do you get the courage to point your finger?

Chang Yu Le is also one of the pedestrians, of course he understands the importance of rivets to aircraft. It's just that he thinks that aircraft from the 22nd century, like sophisticated aircraft, deserve to be different. Like a spaceship in a science fiction, wouldn't it make people laugh off their teeth if they were connected with tight, numb rivets?

As for these mechanics and pilots, they are completely intoxicated by these enormous industrial machines that make them bloody hot.

……

By the time the electric sightseeing car had left the production centre, the professors had become daunted and looked back at the production centre, with awe in their eyes.

Next stop, they came to a seemingly unusual factory.

This factory is small and looks nothing like a normal factory. But when the two automatic doors slipped open and revealed the quiet parking vehicle inside, the crowd on the electric car could not even blink.

“This... this... what is this? ”

“Is that... the complete version of the two aircraft frames that stayed on the production line before?” Two professors stuttered for half a day.

“We intend to test its ability to fly, would you like to…” Ye Qing nodded with a smile, with a "try” bad encouragement in his eyes.

“Ah, can we also participate in the flight test?” Instead, the two professors were pleasantly surprised.

The crafty aircraft has been coated with a golden red coating, and the shining Beast Industry logo is located on the tail hatch doors, on both sides of the headboard. It has no wheel support structure for conventional aircraft, and four retractable equilibrium hydraulic struts replace the wheel.

Just when people were wondering whether to put a guide rail on this aircraft before dragging it out of the warehouse.

The dome of this warehouse suddenly emitted a mechanical motion sound of "clicking ~ clicking ~”, and the huge dome slowly slipped to both sides under the slide.

The two professors “beeped" and stepped onto the automatic ladder into the aircraft.

Changyule wanted to go and didn't dare to tangle his expression. To Changwan Yu's newborn bull was not afraid of tigers. If her father hadn't stuck her, she would surely be the third to enter the cabin.
