Since his family knows his own affairs, Factory 122, as part of Bingcheng Aircraft Industry Group, probably has a few taels of vinegar in the bottle Guo Jingshan and Wang Zhilin are still clear.

The simple thing of the production point Yun 12 is okay, but when it comes to the straight 9 that the manufacturing standard is in line with the international level, there are many places that are inadequate.

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 at the moment, and now they suddenly say that they have solved the problem of the final reducer, which does not sound very in line with the basic principles of the manufacturing industry.

It's like the children who are the bottom few in every exam suddenly take the first place in the school, and the first thought of the parents is definitely that there is something greasy in it, and I am afraid that it is not 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 asked what was going on.

After all, Wang Zhilin is just a rising young engineer, and it is not easy to speak directly on this occasion, but Guo Jingshan doesn't care about that, and asks directly:

"Tell me, what's going on? I don't know what happened to Factory 122? How did you suddenly solve the problem of the final drive? ”

The person who had just knocked on the door had just whipped out his breath, and it seemed that he had been rushing upstairs all the way:

"It's not the 122 factory to solve it by itself, they say that there are suppliers who can provide new raw materials and parts, and they say they can't understand it on the phone, please go to the factory to have a look."

He was just a secretary who was purely engaged in administration, and was not responsible for any technical work.

"Please let me ......"

Guo Jingshan subconsciously lowered his head, only to find that the telephone receiver on his desk had been pushed aside by the large pile of drawings that had just been laid out, no wonder he needed to call himself through others.

Wang Zhilin, who found out that he was in trouble, scratched his head a little embarrassedly.

However, for the sake of him just solving a big problem, Guo Jingshan didn't say anything, just put the earpiece back in place, then got up and picked up two overalls from the hanger next to him, put one on himself, and then threw the other one to Wang Zhilin.

"Let's go, come with me to have a look, and by the way, report what you found to the factory."

"Oh, yes!"

As an engineer responsible for the research and development of the straight 9 transmission system, Wang Zhilin naturally went to the 122 factory on weekdays, but he was personally named and brought over by the chief engineer in the past and today, and the meaning of this is naturally very different.

……

When the two of them came to the workshop in the commuter car in the factory, a middle-aged man wearing a hard hat ran all the way to Guo Jingshan, and muttered as he walked:

"Lao Guo, I can wait for you, the phone call I called you just now has been busy, I am really anxious, come on, come quickly, ...... today"

After speaking, he took one of the latter's hands and was about to go inside, until he turned around, he found that Guo Jingshan was still followed by another person, and he suddenly stopped his hand movements, and his face became a little stiff:

"This little comrade is ......"

As the general manager of Bingcheng Aircraft Industry Group, he still has to hold up his image in front of outsiders.

If the scene just now spreads, I'm afraid it won't have a good impact.

"Oh, a young comrade from the research institute, when the secretary came to look for me, he just told me that he had found the key problem of weak power input of our navy helicopter, so he brought him with him."

And Wang Zhilin, who was standing a little back, was in a stupor from the moment he came in.

Cui Wenxue, the general manager, had only seen him twice when he had just joined the training and at the group meeting at the end of last year, and he should have looked like a very old-fashioned little old man.

And that's the result?

It wasn't until Guo Jingshan introduced himself that Wang Zhilin reacted.

With such an opportunity to show his face in front of the leader, Chief Engineer Guo has almost fed him in his mouth, and if he can't take it again, then no one else can be blamed.

"Hello Mr. Cui, I am Wang Zhilin from the structural design office."

Wang Zhilin's self-positioning is very accurate.

Compliments, that must be of similar status to be valuable.

I am a small fish and shrimp who have just joined the company for the second year, and talking too much will only make the general manager feel annoyed, and it is enough to introduce my position and name.

Anyway, judging from today's plot, there will definitely be no chance for him to show his face in the future.

"Okay, little comrade, come over too."

Cui Wenxue really didn't care much, just said casually, then turned around and walked towards the workshop with the two of them.

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 care too much, after all, this kind of news has often been received in the past, and in the end most of it is gone, but today people directly sent me an encrypted email, which is a few steel samples, and a performance test report."

Cui Wenxue, who was in front of him, paused at this point, as if he was calming down, before continuing:

"I didn't understand it at first, I thought it was the bearings and gearbox gears used in the car, and I was thinking about how the quotation was so much more expensive than the parts imported from Japan, and it took a long time to find out that people meant to use it for helicopters, so I hurriedly brought things to find the engineers in the factory......"

Qi City, Qiqihar is the abbreviation of its vicinity.

Although Beiman Special Steel has been merged into a 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.

And if you want to say what the most famous products of Bingcheng Aircraft Industry Group were in the 90s, it was definitely not the "main" products of helicopters and transport planes, but cars.

Songhuajiang mini van.

From the end of the 80s to the beginning of the 21st century, the most mainstream models on Northeast Street.

It is also the main contributor to helping the whole group survive this cold winter.

In particular, the following Dongan Engine Company, if it had not introduced a large number of gasoline four-cylinder engines for micro vehicles that had been digested and absorbed, and even the aviation industry had not heard of the turboprop 5 by relying on the production alone, it would have been a yellow stall long ago.

In fact, the reason why Cui Wenxue was able to become the general manager of the group at this relatively young age was because he started from being in charge of Songhuajiang Automobile.

So it's no wonder that he kept thinking about car parts at first.

As they spoke, the three of them had come to the depths of the factory, where a group of people in blue or gray overalls were surrounding.

"I don't know much about airplanes, let the responsible comrades here in the workshop introduce the specific situation."

Cui Wenxue has been here for a while, but Guo Jingshan has just come over, and the chief engineer of the group is not seen every day, so a group of people hurriedly greeted:

"Mr. Guo, you're here."

In the hearts of the people responsible for building aircraft in Factory 122, Guo Jingshan's status is probably slightly higher than Cui Wenxue.

Although there is a lot of money to be made by building cars these days, who can still have a dream when engaging in aviation.

A few years ago, it was Guo Jingshan who was running around under pressure, and even went to the Navy to issue a military order in front of Commander Liu, who was born in the navy, and signed a contract for the troops stationed on Hong Kong Island, turning the Zhi-9, a big job they had raised by themselves, into a regular job.

In fact, even Cui Wenwen built a car in the first place 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 indeed good, the accuracy of the gear bearing components we produced before can only reach E grade, the French original is D grade, so the life can only be imported, if you replace it with new materials, even if you maintain the previous processing accuracy, the overall life can be increased to 4-5 times the original 4-5 times, more durable than imported parts......"

"There is also the transmission bevel gear, which not only has a high surface hardness, but also has a good core toughness......"

The first few workshop engineers said a word to Guo Jingshan about the general situation of this material.

To sum it up, it's strong.

As long as the supporting process can keep up, there will be no big problem with the entire transmission system that has plagued our helicopter for more than ten years.

If the machining accuracy can be improved by the way, it is not a problem to hang the original goods at all.
