Who has ever encountered this kind of treatment?
Suddenly surrounded by dozens of strong men in black, the faces of these mechanics and pilots were filled with inquiring expressions similar to meeting online friends.
The object of inquiry was naturally the backbone of the company, Chang Yuyue.
Chang Yuyue was also stunned. He had never encountered such a scene in his life.
"Why … why?" Two professors from Tianfu City's aviation university spoke hesitantly. The aerospace and aviation major had exposed them to similar confidentiality agreements in the past. But when signing that kind of agreement, there were obviously not dozens of strong men around.
"Because you are about to visit a production base that can change the future of aviation. Because this is a commercial cooperation, we must eliminate the possibility of leaks in advance." The Master Metal Expert was still expressionless. He was more businesslike than the old captain in spy TV series.
Chang Yuyue didn't say anything and directly signed his name on the confidentiality agreement.
This treatment not only didn't make him feel the slightest bit of resentment, but it filled his heart with indescribable surprise.
The backbone of the company had written, so the rest of the people naturally couldn't be indifferent. It was just that they read the confidentiality agreement over and over again several times. In the end, the two professors who had research collaborations with Tianfu Aviation Industry Group kept cursing the company in their hearts.
Changing the future of aviation?
Even Tianfu Aviation Industry Group, which designed Hua Xia's first stealth fighter, the J-20, didn't dare to say this. At most, they only dared to say that they would strive to catch up with developed countries and strive to become an international first-class aviation industry group in the next ten years.
After twenty minutes of tossing and turning, the legendary factory was finally opened to Chang Yuyue and the others. They took two special electric sightseeing vehicles and drilled into the factory like fish in a pond.
All the whispers and suspicions disappeared as soon as they went in.
They seemed to have walked into a giant factory. The sightseeing electric vehicle that could accommodate six people couldn't even touch the edge of the base in front of the production line of exquisite aircraft. Two exquisite aircraft frames made of alloy were placed at the end of the production line, which was now only for viewing.
But this also made everyone realize that when the production line in front of them was finally completed, the huge and strange aircraft above their heads could be continuously produced like the production of canned food in an assembly line factory.
When the sightseeing vehicle wandered to hundreds of magically modified five-axis machining centers, the two professors couldn't bring out any other emotion except to breathe hard. Their silent criticism before entering was completely shattered by everything in front of them.
It was actually a fully mechanized assembly plan?
Whether it was the production of small or large aircraft, as long as it involved carrying people, it was all manually assembled.
The reason for the manual assembly was not only because it involved complicated mechanical components, but also because modern aircraft used a large number of lightweight composite materials.
Lightweight composite materials had the advantages of high strength and light weight. In an aircraft with accurate weight reduction down to the gram, whoever could use more lightweight materials would win in terms of economy. However, lightweight composite materials had many insurmountable problems, such as the difficulty of welding.
Different metal materials had different melting points. If two materials were welded together, the welded part would become quite fragile. If it was used in an aircraft, the vibrations produced by the flight alone would cause the aircraft to disintegrate.
Even if they were aware of this, lightweight composite materials were either formed in one piece or riveted. However, when a certain part of the body broke down and disintegrated in mid-air, one could still find a lot of lessons learned from a lot of blood and tragedies in the history of aviation accidents.
The process of assembling an aircraft was so demanding that every assembly worker needed to use a special torque wrench with a counting function to collect the number of revolutions of the screw above.
The degree of tightness of all the screws was maintained the same, which allowed the aircraft to avoid local structural abnormalities caused by resonance during flight.
The production line in front of them completely broke this assembly plan. Whether it was the hundreds of five-axis machining centers or the fully automated mechanical hands all over the production line, it showed that they did not need assembly workers. Everything was done with machines.
At the end of the production line were two mountain-like gantry welding centers.
The height of the welding centers was more than 20 meters. From the diameter of the workbench and the sliding rails below, the two professors easily guessed that these two gantry welding centers were the final process to complete the assembly of the aircraft.
This process was called riveting the skin in traditional production.
The outer shell of the aircraft was connected by rivets because the skin of the aircraft was made of thin aluminum alloy, which could not be welded at all. In addition, welding would also bring about structural strength differences, welding residual stress deformation, and other defects.
When the aircraft flew at high speed, the vibration of the body was very strong. If the skin was welded, it was very likely that a piece of skin with welding defects would be torn, and then like a piece of torn paper, the tear would quickly expand.
"You plan to use welding to install the skin?" The eyebrows of the two professors kept shaking. "Or is it an automatic welding process?"
"Is there a problem? Any aircraft has to undergo a structural static test. If we dare to design like this, we are confident that we will pass the test. "Ye Qing certainly understood the thoughts of the two professors. They must think that Monster Industries was crazy.
However, technology was used to break things. The existence of the rivet process did not prove that it was better than the welding process. It was just limited by the material and body design technology that engineers could only use rivets.
There were more than 100,000 rivets on the skin of a passenger aircraft. The rivets were considered extra weight. Using welding technology, naturally, could save a lot of weight.
The two professors murmured and opened their mouths a few times, but in the end, they could not find any reason to refute.
This was because they had never seen the delicate aircraft, and they had never heard of the equipment in front of them. They did not dare to think about it, so how could they have the courage to criticize?
Chang Yuyue was also one of the insiders. Of course, he understood the importance of rivets to the aircraft. However, he felt that an aircraft from the 22nd century like the delicate aircraft should be different. It was like a flying ship in a science fiction movie. If it was connected with a dense number of rivets, wouldn't it make people laugh their heads off?
As for the mechanics and pilots, they were completely intoxicated by the huge industrial machinery that made their blood boil.
…
When the electric sightseeing car drove out of the production center, the two professors had become timid. They looked back at the production center with awe in their eyes.
The next stop was an ordinary-looking factory.
The factory was not large, and its appearance was no different from a normal factory. However, when the two automatic doors slid open, revealing the aircraft quietly parked inside, the people on the electric scooter did not even blink their eyes.
"What … what … what is this?"
"Is … is this the complete version of the two aircraft frame that was on the production line before?" The two professors stuttered for a long time.
"We plan to test its flight ability, do you two want to..." Ye Qing nodded with a smile, with a "give it a try" in his eyes.
"Ah, we can also participate in the flight test?" The two professors were pleasantly surprised that they received a great honor.
The delicate aircraft was coated with a layer of gold and red paint. The shining Monster Industries logo was located at the rear hatch and on both sides of the nose. It did not have the wheel support structure of a traditional aircraft. Instead, four telescopic and balanced hydraulic struts replaced the wheels.
Just as people were wondering if they should first install a guide track on the aircraft and then drag it out of the warehouse.
The dome of the warehouse suddenly made a "click ~ click ~" mechanical sound. Driven by the guide track, the huge dome slowly slid to both sides.
The two professors went "beep" and stepped on the automatic stairs into the aircraft.
