Chapter 452 Import Substitution

Their own family knows their own affairs. As 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.

The production of a simple thing like the 12 is fine, but when it comes to the Z9 whose manufacturing standards are in line with international standards, it falls short in many areas.

Not to mention the transmission, 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 solved the problem of the main reducer. It sounds true. Not quite in line with the fundamentals of manufacturing.

It's like if a child who was at the bottom of every exam suddenly took the first place in the school, the parent's first thought was definitely that there was something fishy in it, and he was afraid that he was 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.

After all, Wang Zhilin was just a rising young engineer. It was not easy to speak directly on such occasions, but Guo Jingshan didn't need to care about that and asked directly:

"Tell me, what's going on? Do I still 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 had just taken a breath and seemed to have run all the way upstairs:

"Factory 122 is not solving it on its own. 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."

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 to call him through someone else.

Wang Zhilin scratched his head in embarrassment when he realized that he was the one causing the trouble.

However, 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, put one on himself, and then put the The other one was thrown to Wang Zhilin.

"Come on, come with me to take a look, 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 goes to Factory 122 on weekdays. However, the meaning of this is naturally very different when he was personally called and taken there by the chief engineer in the past and today.

……

When the two people arrived at the workshop on a commuter bus in the factory area, a middle-aged man wearing a safety helmet ran up to Guo Jingshan in small steps, and murmured as he walked:

"Lao Guo, I've been waiting for you. The line I called you just now has been busy all the time. I'm so anxious. Come on, come on. Today..."

After saying that, he took one of the latter's hands and prepared to walk inside. It was not until he turned around that he discovered 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 were spread, I'm afraid it would have a bad impact.

"Oh, a young comrade from the research institute, when the secretary came to see me, he just 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, whom he had only met twice before during training and at the group meeting at the end of last year, 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.

Compliments must be of similar status to be valuable.

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."

As expected, Cui Wenxue didn't pay much attention. He just said something casually, then turned around and led the two of them towards the workshop.

Of course, the hand that held 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. I didn't pay much attention to it at the beginning. After all, I often received this kind of news in the past. In the end, most of them just left it alone. 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 talking in front, 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. I was also wondering why the quoted price was so much more expensive than the parts imported from Japan. After checking the data for a long time, I realized that they meant they were for helicopters. Then I quickly brought my things and came to find the engineer 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 90s, it was definitely not its "main" products such as helicopters and transport aircraft, but cars.

Songhuajiang brand mini-van.

From the late 80s 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-vehicles and installed them in large quantities, it would have been in ruins long ago if it only produced turboprop 5s that more than half of the people in the aviation industry had never heard of. .

In fact, the reason Cui Wenxue was able to become the general manager of the group at such a relatively young age was because he started in charge 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 responsible comrade in the workshop introduce the specific situation."

Cui Wenxu has been here for a while, but Guo Jingshan has just arrived, and the chief engineer of the group does not see him every day. A group of people hurriedly said hello:

"Mr. Guo, you are here."

In the hearts 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 and even went to the Navy Commander Liu to issue a military order before signing an order for the troops stationed in Hong Kong Island to build Zhi 9 with their own funds. The big job was changed.

In fact, even Cui Wenwen built cars in order 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 made by the French are D-level, so if the lifespan cannot be improved, they can only be imported. , if new materials are used, even if the previous processing accuracy is maintained, the overall service life 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 leading workshop engineers talked to each other and introduced the general situation of this material to Guo Jingshan.

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.
