Monster Factory Chapter 873: : About to take off
Welcome your visit, please remember the address of this site: cell phone reading, so that you can read the latest chapters of the novel "Exceed Grade Monster Factory" at any time...
Who has encountered this kind of treatment?
Suddenly, dozens of burly men in black were onlookers. The faces of these mechanics and pilots were filled with inquisitive expressions similar to those of netizens meeting.
The object of exploration is naturally the mainstay and constant joy.
Chang Yule was also stunned, he had never encountered such a scene in his life.
"Why...why?" Two Professors from Tianfu City Flight College hesitated to speak. The Aerospace aviation major allowed them to come into contact with similar confidential agreements in the past. But when that agreement was signed, there were obviously not dozens of strong men around.
"Because you are about to visit a production base that can change the pattern of aviation in the future, because this time is a commercial cooperation, so we must eliminate the possibility of leaking in advance." Metal Specialist is still expressionless. The old captain is still on business.
Chang Yule signed his name directly on the confidential agreement without saying a word.
This treatment not only did not give him the slightest plan, but also filled his heart with unspeakable surprises.
The main body has started to write, and these people can't be indifferent. merely they tossed over and read the confidential agreement several times, and the last two Professor, who had cooperation with Tianfu Aviation Industry Group, kept slandering this Company in their hearts.
Change the future aviation landscape?
Tianfu Aviation Industry Group, which designed the China's first stealth fighter jet —20, dare not say this. They dare to say at most, trying to catch up with developed countries, and strive to become a world-class aviation industry group within the next ten years.
After 20 minutes of tossing, this legendary factory building finally opened to Chang Yule and his party. They took two special electric sightseeing vehicles and got into the factory like a fish diving into a pond.
All the whispers and doubts disappeared after they entered.
They seem to walk into a giant Factory, a sightseeing electric car that can accommodate six people. In front of the Exquisite Aircraft production line, they can't even touch the edge of the base. Two Exquisite Aircraft frames made of alloy are placed at one end of the production line, and now it is merely for people to visit.
But this also makes everyone realize that when the production line in front of you is finally completed, the strange aircraft of immense above your head can be produced continuously just like the production line Factory can produce.
While waiting for the sightseeing car to walk to hundreds of demons modified Five-axis Processing Center, the two Aerospace professional Professors could not express any emotions except for breathing hard. Their bellyache before entering the door has been completely shattered by everything in front of them.
It turned out to be a fully mechanized assembly solution?
No matter small or large-scale aircraft production, as long as it involves manned, it will be hand-made assembly.
The reason for the assembly of hand-made, in addition to the complicated mechanical components involved, it is impossible to use an automatic manipulator to guarantee precision, the most important point is that modern|Hyundai aircraft uses a large number of lightweight composite materials.
Lightweight composite materials have the advantages of high strength and light weight. In aircraft whose weight is reduced to the nearest gram, who can use more lightweight materials means winning economically. However, lightweight composite materials have many problems without Fuck clothing, such as difficulty in welding.
Different metal materials have different melting points. If the two materials are welded together, the weld will become quite fragile. If it is used in aircraft, the vibration of flight alone can disintegrate the aircraft volley.
Even if you are aware of this, lightweight composite materials are either integrated or riveted. But because of the structural breakage of a certain part of the airframe, the volley disintegration incident occurred. Looking through the history of aviation disasters, we can still find a lot of lessons drawn from blood and tragedy.
The process of assembling a aircraft frame has been so demanding that each assembly worker requires special torque wrench with counting function to collect the number of rotations of the above screw.
The tightness of all screws are kept the same, so that aircraft can avoid the local structure anomaly caused by resonance when flying.
The production line in front of us has completely broken this assembly scheme. Whether it is hundreds of Five-axis Processing Centers or fully automatic manipulators all over the production line, it shows that they don't need assemblers, and all have machines then it will be alright.
At the end of the production line are two gantry welding centers that look like mountains.
The height of the welding center exceeds 20 Meters, judging from the diameter of the worktable and the sliding tracks all over it, two Professor It’s easy to guess that these two CNC welding Center is done aircraft The last process of assembling.
This process is called riveting skin in traditional production.
All aircraft shells are connected by rivets, because the aircraft skins are all thin-plate aluminum alloys, which cannot be welded at all. In addition, welding will also bring about different structural strengths, and there are defects of welding residual stress and deformation děng děng|etc|wait.
When the aircraft is flying at high speed, the body vibrates very strongly. When welding skin is used, it is possible that a piece of skin with welding defects will be torn, and then like a piece of torn paper, the tear will expand rapidly.
"Do you plan to use welding to install the skin?" The eyebrows of the two Professors kept shaking, "Or the automatic welding process?"
"Is there a problem? Any aircraft must accept the structure Static Test. We dare to design this way and we are sure to pass the test." Of course, Ye Qing understands the ideas in the minds of these two Professors. They must think the Monster industry is crazy.
But technology is used to break, the existence of rivet technology does not prove that it is stronger than welding technology. merely is limited by materials and body design technology, engineers can only use rivets.
There are more than 100,000 rivets on the skin of a passenger plane, and the rivets are extra heavy. The welding technology can naturally save the weight of the huge volume.
The two Professor murmured several times, but in the end they couldn't find any reason to refute.
Because they have never seen Exquisite Aircraft, these devices are even more unheard of. If you can't even think about it, where is the courage to point your finger?
Chang Yule is also considered one of the insiders, of course, he understands the importance of rivets to airplanes. merely he thinks that aircraft from 22nd Century like Exquisite Aircraft, of course, should be different. Just like the flying ship in the science fiction film, if it is connected with dense rivets, wouldn't it make people laugh?
As for these mechanics and pilots, they have completely indulged in the huge industrial machinery that made them blood boiling.
……
When the electric sightseeing car drove out of the production center, the two Professors had become awed. They looked back at the production center, with awe in their eyes.
The next stop, they came to a seemingly ordinary factory.
The scale of this plant is small, and its appearance is no different from the ordinary plant. But when the two automatic doors slid open, revealing the aircraft quietly parked inside, the crowd on the electric car could not even blink.
"This...this...what is this?"
"Difficult...Is it just staying on the production line before, that...the full version of the two aircraft frames...?" Two Professors stammered for a long time~IndoMTL.com~ We plan to test its flying ability , You two, do you want to..." Ye Qing smiled and nodded, with the bad encouragement of "try it" in her eyes.
"Ah, can we also participate in the flight test?" The two Professors were surprised by the glory.
Exquisite Aircraft has been plated with one layer gold and red paint, and the shining Monster industrial logo is located on the rear door and on both sides of the nose. It does not have the wheeled support structure of a traditional aircraft, and has four retractable and balanced hydraulic props instead of wheels.
Just when people were wondering whether to install rails on this aircraft first, and then take it out of the warehouse.
The dome of this warehouse suddenly made a mechanical sound of "click ~ click ~". Driven by the sliding rail, the dome of immense slowly slipped to both sides.
The two Professors made a "beep ~" and stepped on the automatic ladder to get into aircraft.
Chang Yule had a tangled expression that wanted to go but didn't dare, until Chang Wanyu was a newborn calf who was not afraid of tigers. If it weren't for her father's grip, she would have gotten into the cabin third.
