In the morning, a special person led a group of students and arranged food and accommodation.
At noon, a group of students had a taste of the working lunch of the legendary giant state-owned enterprise.
The lunch for ordinary employees of XAC may not be as good as the Xiaozao on Shougang Airlines, but it is also very unique. A group of friends in Zhou Yan's dormitory had a bowl of trouser noodles each, which was a taste of the local characteristics.
Because the factory has a confidential workshop, the management of employees entering and exiting the factory is relatively strict. A group of students who originally planned to travel to Chang'an City could only purchase some daily necessities in the small supermarket downstairs of the dormitory, and then had to go back to the dormitory.
.
Zhou Yan, who also had nowhere to go, bought his daily necessities, tidied his bed a little, then opened his suitcase and took out several pairs of high-end gift boxes.
"Lao Liu, what do you want to do? Are you trying to make a mistake? The instructor has warned you that you are not allowed to leave the factory..."
"You don't know this, right?" Zhou Yan grinned, "The advantage of working in the aviation system is that you can always meet acquaintances wherever there are aviation companies! I plan to visit my dad's classmates in the evening
, who of you would like to go together?"
"never mind!"
After saying that, Zhou Yan took his walnut machine and left the dormitory...
Zhou Yan originally thought that his classmate, Li Jianguo, who was cheap, would have to keep going. Who knew that as soon as he called, the other person directly said: "Xiao Feng, are you flying to the west? My home is..."
Li Jianguo's classmates were naturally very happy about Li Tianfeng's visit: in a confidential unit, it is more troublesome to visit...
"Xiao Feng, look at you, you came right away and you brought so many things with you!"
"This pair of old wild ginsengs was prepared by my father for you. These snow clams were specially ordered by my mother to be handed over to Aunt Lin..."
"It's expensive, come in and sit down!"
After entering, Uncle Yan smiled and made tea: "Xiao Feng, I have already seen Xifei. How is it different from your Shen Fei?"
"It can only be said that each has its own characteristics," Zhou Yan picked up the teacup and blew on it, "The factory here in Xifei has more rough beauty, but ours at Shenfei has a classical beauty..."
"I heard from your dad that you have already been admitted to the school," Yan Fei said with a smile. "In addition to the thesis you just published, after graduating from graduate school, it should be a sure shot to enter the design school?"
"I can only say that it will depend on the situation at that time!"
"You kid, why are you being so humble to me?" Yan Fei said, a little annoyed. "During the Chinese New Year, your dad boasted to me that Shenfei Design Institute had designated you as the future flag-bearer!"
As he spoke, Yan Fei looked at Zhou Yan with a smile: "Have you ever thought about coming to Xifei?"
"Uncle Yan, you are my father's brother, so I won't hide it from you. I plan to build a carrier-based aircraft..."
The room suddenly became silent.
"Xiao Feng, you have to know that the development of a carrier-based aircraft is much more difficult than a land-based fighter..." Yan Fei looked serious, "The fighter next door is not bad, but it has not been developed yet to be able to compete with the beautiful country.
Longer and shorter carrier-based aircraft.”
"There is a challenge only if it is difficult!" Zhou Yan smiled, "When the time comes, maybe there will be a chance to cooperate with Xifei!"
After all, Yan Fei was from within the aviation system. When Zhou Yan said there was an opportunity for cooperation, he knew what this guy was talking about.
"Xiao Feng, you are so ambitious. Do you even plan to steal our Xifei's business?"
"He who can do it should work harder!"
"Smelly boy..."
After having a dinner at Yan's house, I returned to the dormitory, answered a series of questions for the curious babies, and then went to bed with my head covered.
The next day, the internship officially started.
In order to allow students to systematically and comprehensively understand the manufacturing process of aircraft, the school specifically contacted the manufacturer and placed students in various assembly processes in turns.
What surprised Zhou Yan's roommates was that the first process of the six-person group's internship turned out to be the carbon fiber molding process that they had already played with.
Although the carbon fiber structure on the MA-60 is much larger than the structure used on the drone, no matter how large the structure can be, the basic molding process is the same.
Of course, in XAC's construction workshop, a group of people were exposed to more comprehensive processing techniques than when they were doing it themselves: at least they saw the mold forming process in XAC's workshop.
The shape curves of aircraft are relatively complex, and the carbon fiber molding process is more suitable for such parts. However, precise shapes require precise molds.
Complex curved surface mold processing involves the blind spot of our friends: multi-axis linkage CNC machine tools.
Although only the simplest three-axis milling machine is used to process the mold, it is enough to amaze a group of novices.
What surprises the newbies even more is yet to come...
After entering the formal production line, I watched the skins being erected on the fish-bone-like horizontal and vertical reinforcement beams, from the initial beams to the formation of the aircraft fuselage step by step...
"This is aircraft manufacturing?"
"Where are you going?" The teacher leading the team said with disdain on his face, "You should all know the An-225 Dream, which is eighty-four meters long and has a wingspan of eighty-eight meters. Just imagine, that aircraft's
How big should the production line workshop be..."
After the fuselage is formed, the wings are installed on the main wing beams, and then various components can be added: landing gear, ailerons, fuel tanks, pipelines...
During the internship, Zhou Yan's friends were all serious and took notes constantly. They were also serious when they were able to operate by themselves.
Zhou Yan, who was traveling with him, had the same performance, but in his free time, Zhou Yan was not thinking about internships, but an aircraft that looked similar to the MA-60 - a carrier-based early warning aircraft platform.
Similar body shapes, the same twin-engine turboprop power, and the same straight-up monoplane. The only difference may be the load and engine output.
At present, the benchmark for carrier-based early warning aircraft in the world is the E-2C. The aerodynamic shape of the aircraft was developed more than 30 years ago, and the turboprop engine it can carry has become a classic after more than 30 years of improvements.
The aerodynamic shape is not difficult for us. The only one that is more difficult for us during the research and development process is the T56 turboshaft engine of RR Group.
Zhou Yan does not and cannot have information on the T56 engine at hand, but he does have a similar product equipped with the self-developed early warning aircraft of Different Space Wotu, a 4,000-kilowatt turboprop engine. Although the performance may lag behind, the materials can be replaced.
After using the latest technology design, it should be able to reach the level of the latest improved T56.
In the real world, Zhou Yan once stuffed a set into the Navy's server. In this mission world, Zhou Yan plans to develop it himself.
Zhou Yan is not a person who likes to procrastinate. After setting the goal, he starts taking action.
The turboprop engine Zhou Yan has on hand is the JZWJ-4000 with a power of 4,000 kilowatts, while the similar product equipped with the E-2C has a power of 5,110 kilowatts.
However, according to Zhou Yan's calculations, after the JZWJ-4000's fan blades are changed to the most advanced high-efficiency blades, the power should be increased to 5,000 kilowatts, and the overall weight of the engine should also be reduced to the level of the T-56.
For more specific calculations, Zhou Yan needs to make an overall model of the engine before he can determine it.
After a week of hard work, a group of reserve workers finally arrived at the weekend.
However, today is different from the past. Many students who have been exposed to the actual situation have a sense of urgency about the future and gather together in twos and threes.
Zhou Yan originally planned to stay in his dormitory to design, but Yan Fei suddenly called and asked him to go home for dinner...
