Chapter 452 Import Substitution
My family knows their own business. As a part of the Bingcheng Aircraft Industry Group, Factory 122 knows how much vinegar there is in the bottle. Guo Jingshan and Wang Zhilin still know clearly.
Simple things like the production point 12 are fine, but when it comes to the straight 9 whose manufacturing standards are in line with international standards, there are many areas where it falls short.
Not to mention the transmission device, which is the most important core component of the helicopter, even the main rotor and tail rotor can only be imported from France. Now they suddenly say that they have given up the problem of the main reducer. Solved, it does not sound consistent with the basic principles of manufacturing.
It’s like a child who has always been at the bottom of every exam suddenly takes the first place in the school. The parent’s first thought is definitely that there is something fishy in it, and he is afraid that he is cheating.
In the same way, the first reaction of the two people in the office when they heard the news was not surprise, but further questioning of the visitor.
Wang Zhilin is just a rising young engineer after all. It is not easy to speak directly in this kind of situation, but Guo Jingshan does not need to care about that and asked directly:
"Tell me, what's going on? I still don’t know what’s going on at Factory 122? Why did the main reducer problem suddenly be solved?”
The person who just knocked on the door just took a breath and seemed to have rushed upstairs:
“Factory 122 cannot solve it by itself. They said there are suppliers who can provide new raw materials and parts. They said they couldn’t explain the details on the phone. Please go to the factory and have a look.”
< br>
He is just a secretary who is purely engaged in administration and is not responsible for any technical work.
"Please let me go..."
Guo Jingshan lowered his head subconsciously, and then realized that the phone receiver on his desk had been pushed aside by the pile of drawings that had just been laid out. No wonder he needed Call yourself through others.
Wang Zhilin scratched his head in embarrassment when he realized that he was the one causing the trouble.
But seeing that he had just solved a big problem, Guo Jingshan didn't say much. He just put the receiver back in place, then stood up and picked up two pieces of work clothes from the hanger next to him. He put it on himself and then threw the other one to Wang Zhilin.
"Let's go take a look with me, and report what you discovered to the factory."
"Hey, okay!"
As the engineer responsible for the research and development of the straight-9 transmission system , Wang Zhilin naturally went to Factory 122 on weekdays, but the meaning was naturally very different when he was personally called and taken there by the chief engineer in the past and today.
......
When the two people came to the workshop in the factory commuter car, a middle-aged man wearing a safety helmet ran up to Guo Jingshan in small steps, and While walking, I muttered:
"Lao Guo, I've been waiting for you. The line I called you just now has been busy all the time. I'm really anxious. Come on, come on. Today..."
After saying that, I took one of the latter's hands. He was about to walk inside, but when he turned around, he realized that there was another person following Guo Jingshan. He immediately stopped his movements and his expression became a little stiff:
"This little comrade is... …”
As the general manager of Bingcheng Aircraft Industry Group, he still has to maintain his image in front of outsiders.
If the scene just now spreads out, I'm afraid it will have a bad impact.
"Oh, when the secretary of a young comrade from the research institute came to see me, he happened to tell me that he had found the key problem of the weak power input of our naval helicopter, so he brought him with him."
Wang Zhilin, who was standing slightly behind, was in a daze from the moment he entered.
General Manager Cui Wenxue, he had only met him twice before when he was newly hired for training and at the group meeting at the end of last year. He seemed to be a very old-fashioned little old man.
Is this the result?
Wang Zhilin didn’t react until Guo Jingshan introduced himself.
Chief Engineer Guo has almost fed him this opportunity to show his face in front of the leader. If he can't take it anymore, he can't blame others.
"Hello, Mr. Cui, I am Wang Zhilin from the structural design office."
Wang Zhilin's self-positioning is very accurate.
Flattery only has value if you are of similar status. As a little fish and shrimp in my second year of employment, talking too much will only annoy the general manager. It is enough to just introduce my position and name.
Anyway, judging from today's plot, there will definitely be no shortage of opportunities for him to show up later.
"Hello, little comrade, come here too."
Cui Wenxue really didn't pay much attention, he just said casually, then turned around and led the two of them towards the workshop.
Of course, the hand that grabbed Guo Jingshan just now must have been loosened.
“Two days ago, I received a fax from Qi City, saying that they can supply us with a new grade of bearing gear steel. At the beginning, I didn’t pay much attention to it. After all, this I often received this kind of message in the past, but in the end most of it was ignored. As a result, someone directly sent me an encrypted email today, which contained several steel samples and a performance test report.”
Cui Wenxue, who was in front of us, paused here, seeming to calm down, and then continued:
"I didn't understand it at first. I thought they were car bearings and gearbox gears, and I was wondering. I wonder why the quoted price is so much more expensive than the parts imported from Japan. After checking the data for a long time, I found out that they meant it would be used for helicopters, so I quickly brought the things over to see the engineers in the factory..."
Qi City, the abbreviation of Qiqihar in its surrounding areas.
Although Beiman Special Steel has been merged into part of Northeast Special Steel, after all, it has only been a year, and most people are still accustomed to treating it as a separate factory.
As for the most famous product of Bingcheng Aircraft Industry Group in the 1990s, it was definitely not its "main" products such as helicopters and transport aircraft, but cars.
Songhuajiang brand mini-van.
From the late 1980s to the early 21st century, it was the most mainstream car model on Northeast Street.
He is also the main contributor who helped the entire group survive this cold winter.
Especially the Dongan Engine Company below. If it had not introduced and absorbed the gasoline four-cylinder engines for mini-cars and installed them in large quantities, it would have produced turboprop 5s that more than half of the people in the aviation industry had never heard of. , has long been a yellow stall.
In fact, the reason why Cui Wenxue became the general manager of the group at such a relatively young age was because he started out as the supervisor of Songhuajiang Automobile.
So it’s no wonder that he initially focused on automotive parts.
While they were talking, the three of them had reached the depths of the factory, where a group of people wearing blue or gray work clothes were surrounding them.
“I don’t know much about airplanes. Let the comrade in charge in the workshop introduce the specific situation.”
Cui Wenxue has been here for a while, but Guo Jingshan has just arrived. , the chief engineer of the group is not seen every day. A group of people quickly greeted:
"Mr. Guo, you are here."
In the minds of those responsible for building aircraft in Factory 122, Guo Jingshan's status is probably slightly higher than Cui Wenxue's.
Although you can make a lot of money by building cars these days, who can still dream of aviation?
In the past few years, it was Guo Jingshan who was running around under pressure. He even went to Commander Liu, who was born in the navy, to issue a military order before signing an order for the troops stationed in Hong Kong Island. The big job that was done with self-raised funds was turned into a regular job.
In fact, even Cui Wenwen built cars in the beginning just to provide sufficient funds for the aircraft project.
"Mr. Guo, I took a look at the test data of this sample. The surface hardness is really good. The accuracy of the gear bearing components we produced before can only reach E level. The original ones from France are D level, so the lifespan is If you can’t get it up, you can only import it. If you use new materials, even if you maintain the previous processing accuracy, the overall lifespan can be increased to 4-5 times the original, which is more durable than imported parts..."
"There are also transmission bevel gears. This steel not only has high surface hardness, but also has good core toughness..."
The first few workshop engineers talked to each other and introduced the general situation of this material to Guo Jingshan. For a moment.
To sum it up, it is very strong.
As long as the supporting technology can keep up, the entire transmission system that has troubled our helicopters for more than ten years will not be a big problem.
If the processing accuracy can be improved by the way, then lifting the original goods will not be a problem at all.
