Chapter 234 Static verification of the whole machine
Finally, everything is ready!
The verification test of the whole machine is ready to start this morning.

In the static test workshop, technicians are doing the final inspection, whether there is any problem with each load point, whether each sensor is normal, whether each instrument is reset to zero, etc.

Zhao Mingzhi, Li Guangshu and other high-level executives from the design office came here, both a little excited and a little nervous.

"Old Zhao, I really hope to pass this static verification test once."

Zhao Mingzhi put his gaze on the verification machine and didn't say anything. Maybe he was also thinking in his heart that he must pass the static verification test of the whole machine at one time.

An expert next to him reminded, "This is the static verification test of the whole machine. Looking at the previous static tests of the whole machine in China, there are very few cases that pass it at one time."

Zhao Mingzhi still didn't say anything, and after looking at it for a long time, he looked away from the verification machine and said with emotion.

"Seeing our static verification test of the whole machine reminds me of when I first started working, I was also doing the static verification test of the whole machine at that time, but there were no such good conditions at that time."

This seems to have brought back memories of Li Guangshu, and he also said with emotion, "At that time, we made sandbags for the static verification of the whole machine, and even tied bricks with ropes and hung them on various points of the plane. force verification test."

"There are a lot of people now. Look at our static verification test system for the whole machine. The hydraulic cylinders and sensors are all controlled by computers. They have completely changed their guns."

"..."

While chatting like this, a technician in charge trotted all the way over and reported loudly, "Mr. Zhao, the check is correct again, can we start?"

Zhao Mingzhi raised his hand to check the time, and said, "Wait a little longer."

Li Guangshu next to him also checked the time, it was 42:[-] am, "Boss, they should be here soon."

This is the static verification test of the whole machine, which can be regarded as an important milestone for this transport helicopter. Lin Feng is going to come and have a look in person.

A few minutes later, there was movement outside the factory. It seemed that two or three cars had arrived. Zhao Mingzhi waved his hand and said, "Let's go, the boss and the others should have arrived."

Under the leadership of Zhao Mingzhi, everyone went to the gate of the static verification test plant to greet them. Sure enough, several people including Lin Feng had already arrived.

"boss!"

"Boss, hello!"

Everyone greeted Lin Feng proactively, and Lin Feng waved, "Come on, let's go in and take a look at our static verification test of the whole machine."

Everyone crowded around Lin Feng like stars and walked into the static verification test plant. Once in, including Lin Feng, they immediately saw the verification machine.

Wang Yalong was the first to say loudly, "This is our first verification machine, and it looks like it makes people feel excited."

He Hua said, "Entering the static verification test stage of the whole machine, we are not far from our first prototype."

Lin Feng also looked at the ready verification machine, and said loudly, "At nine o'clock in the morning, the static verification test of the whole machine will officially start."

It is now 56:4 in the morning, and there are still [-] minutes before [-]:[-]. All the experimenters and technicians are in their positions one after another, preparing for the static verification test.

As the time passed minute by minute, Ruoda's workshop was completely quiet until a sudden ringing of the bell broke the silence.

Nine o'clock in the morning!
The bell stopped, and a loud voice resounded throughout the factory building, "Attention everyone, the static verification test of the whole machine has begun!"

As soon as the sound fell, the entire static verification system started to work, making a buzzing sound, and the hydraulic cylinders began to be slowly pressurized, and the transport helicopter began to bear the static load.

10%, 20%, 30%...

Some people looked at the transport helicopter under static load, and some people also looked at the display data of various instruments.

Reaching 50% of the design load, the static load does not continue to increase, but stabilizes, and the time will reach 10 minutes.

"It looks fine."

"The numerical control on each instrument is very stable."

"With 50% load, I believe our transport helicopter is fine."

"..."

There were conversations in the originally quiet factory building. Generally speaking, everyone is quite confident about the 50% static load.

After 10 minutes, the static load began to be unloaded, and then inspectors and technicians began to conduct related inspections on the demonstrator.

The first is the appearance inspection, whether the appearance is normal, whether there is obvious deformation, whether there are cracks or breaks, and then the inspection of related dimensions.

Because it is only 50% of the design load, the inspection is not complicated, and with several inspectors and technicians working together, the speed is relatively fast.

Within a few minutes, loud reports sounded and floated into everyone's ears one after another.

"Appearance inspection is normal!"

"Size check OK!!!"

"..."

Hearing these reports, many people showed smiles. Everything was expected, and the 50% design load was really no problem, and it passed smoothly.

However, the real test will soon begin.

After checking everything is normal, the next stage of static verification test will start again, and the testers and technicians are busy again, starting to prepare for this stage of static verification test.

It takes time to prepare. Zhao Mingzhi suggested, "Boss, let's sit down and have a drink of tea. I have something to report to you at work."

Lin Feng knew that it would take time to prepare for the next stage of the static verification test, so it would be better to sit down and have a drink of tea than to stand here and wait.

So, he waved his hand and said, "Let's go, let's go and listen to Director Zhao's work report."

A group of people left the static force verification workshop, walked into the R&D building of the Helicopter Design Institute, took the elevator to the top floor, and sat down in a reception room.

While drinking tea, chatting.

"Well, it's much more comfortable here. Our static testing workshop doesn't have a central air conditioner, so it feels a bit cold."

"Wait a minute is a 100% design load static verification test, I don't know what the result will be."

"The 50% design load static verification test just now is just an appetizer, and the 100% design load static verification test that will be carried out later will be the real test."

"Don't make any problems, it must pass smoothly."

"..."

Everyone chatted for a while while drinking tea, and then Lin Feng waved his hand and said, "Director Zhao, how is the design progress of our heavy-duty armed helicopter?"

Zhao Mingzhi quickly put on a straight face, and reported the recent situation.

Generally speaking, the design progressed very smoothly, and another batch of design drawings were completed, but some difficulties were encountered during the design process. Every time a technical problem was encountered, relevant experts and designers sat down and carefully analyzed and discussed.

If you really can't solve it, write down the problem and ask Mr. Lin for technical guidance when he comes over.

"Boss, we also encountered some technical problems, some of which we solved by ourselves, and a few others that need your guidance."

"In addition, the design drawings of some more important parts have been drawn. Would you like to take a look at them?"

Lin Feng said, "Let's go in the afternoon. If you don't understand, you can ask me. We can even hold another technical exchange meeting like before. I will personally participate in the technical exchange with everyone."

"As for the design drawings, I must have a look at them. It's still the old rule. Since I have been to the design office, I have to go through the design drawings of the important parts one by one."

If you have seen it yourself, you will definitely feel at ease, and you will have a bottom in your heart, and you will have a certificate for the design quality of this heavy-duty armed helicopter.

After chatting for a while, especially after listening to Zhao Mingzhi's report, Lin Feng felt that the time was almost up, got up and said, "Let's go, let's go to the static verification test plant to see what the 100% design load static verification test will be like. "

Our group went to the static test workshop again.

"Report, the second phase of the static verification test is ready, please instruct!"

Lin Feng waved his hand, "Start the second phase of static verification test!"

Thus, the second stage of the static verification test began. In everyone's eyes, the entire static verification test system began to work, and the hydraulic cylinder began to be slowly pressurized under the control of the computer. This verification machine began to bear pressure from various hydraulic pressures. Cylinder pressure and load.

10%, 20%, 30%...

The load began to increase, and it didn't take long for it to exceed 50% of the design load, and it was still rising. Everyone in the entire factory fell silent, only the slight hum of the static verification test system.

Some people looked at the verification machine under static load, some people looked at the data on various instruments, and some people also pricked up their ears.

Experienced people know that under a strong static load, if the verification machine cannot bear it, if some deformation occurs, certain sounds may be emitted.

They pricked up their ears and listened carefully to see if there was any sound coming from them. Of course, having a sound was definitely not a good thing, and it meant that certain parts began to deform.

80%, 90%, 100%...

The static load finally reached 100% of the design load. At this time, some people inevitably became nervous, and some young designers even prayed in their hearts, God bless, there will be no problems.

Lin Feng, Zhao Mingzhi and others looked calm, but they couldn't see anything for the time being.

The static load reached 100% of the design load, and the timing started. It was still 10 minutes, and the scene was still quiet.

A designer wanted to say something, but his supervisor hurriedly waved his hand to stop it. It is not appropriate to break the silence at this time, because many people are listening attentively.

The time passed by minute by minute, and this 1 minutes seemed to be much longer than the last 1 minutes.

Finally, 10 minutes was up, and the unloading began, and the originally relatively quiet scene finally became lively.

"I don't know what's going on, but judging from the data of the instruments, there's nothing unusual about it."

"Don't let anything go wrong!"

"It would be great if you can pass it once."

"..."

Amidst everyone's conversation and discussion, several inspectors and technicians got busy and started various inspections, including appearance and size inspections.

The inspection time this time is obviously longer and more comprehensive.

After a long time, the result finally came out, and a designer in charge ran over quickly and said loudly.

"Report to Mr. Lin, report to the leaders, the appearance inspection is normal, the dimensional inspection is normal, and the 100% design load static verification test has passed perfectly!"

As soon as his voice fell, cheers erupted in the factory instantly.

"Great, perfect pass!"

"This is 100% of the design load, and our verification machine has not deformed at all!"

"It was so exhilarating, it felt like a dream."

"..."

Lin Feng was also in a good mood to pass the 100% design load static verification test perfectly at one time, although this may be within his expectation, he said loudly, "Director Zhao, your design is good, and it fully meets the requirements of the design technical outline. Require."

Zhao Mingzhi immediately said modestly, "Everything is inseparable from the guidance of the boss."

The 100 design load static verification test passed perfectly. Lin Feng looked at the time, and a morning had passed, and it was now past 12 o'clock.

He waved his hand and said, "Let's go, the following static verification test will be handed over to our technicians. Let's go to dinner and hold a technical exchange meeting in the afternoon."

A group of people crowded Lin Feng out of the static verification test workshop, and the static verification test will continue here in the afternoon.

There is also 150% design load static verification, and the maximum design load static verification test.

Passing the 100% design load static verification test is only considered a pass, indicating that the design basically meets the requirements and is basically successful.

If it can pass the 150% design load static verification test, it means that the design is very good, absolutely excellent level.

However, Lin Feng didn't plan to stay here any longer in the afternoon, he just planned to hand over the follow-up static verification test to relevant personnel, and just listen to the results by himself.

in the afternoon.

The static verification test continued here, and after some preparations, the third phase of the static verification test began.

Compared with the morning, there are only slightly fewer people in the factory, and there are still many people at the test site.

"Report, the third phase of the static verification test is ready, please instruct!"

Mr. Lin is not here. Li Guangshu is the person with the highest position here, and he is also the commander-in-chief here. He waved his hands and said loudly, "Start the 150% design load static verification test!"

Soon, the static verification test system started to work, and the hydraulic cylinders began to increase the load on the verification machine.

The atmosphere of the whole scene seemed to be tense invisibly.

Very quiet!
Almost everyone's eyes were on the verification machine, which was subjected to static load again. In this tense silence, the static load was slowly rising.

After a few minutes, the static load reached and exceeded 100% of the design load and continued to increase.

110%, 120%, 130%...

The atmosphere of the whole scene was almost so tense that water could be squeezed out, which had far exceeded the design load, and some people found their hearts beating continuously.

Li Guangshu's face seemed to be relatively calm, but almost no one noticed that his fists were clenched tightly, probably his palms were already sweating.

Don't go wrong!

Some technicians began to pray silently in their hearts.

The scene was quiet, except for the slight hum of the static verification test system, no one spoke, and no one made even the slightest sound.

In stark contrast to the static verification test plant, the huge conference room was very lively, with dozens of people sitting there.

The notice has been sent out in the morning. If you encounter technical problems that cannot be solved during the design process, you can participate in this technical exchange meeting if you have any questions during the design process.

As a result, dozens of people came at once, and the meeting room was almost full. Most of them came with questions, and a small number of people just came to listen, and came with a learning attitude.

"Is it true? Is it really Mr. Lin who conducts technical exchanges with us?"

"I have a deep memory of the last technical exchange, and it is also the first time I really admire Mr. Lin. It turns out that his technical attainments are as high as the rumors."

"I was suddenly a little nervous. I will be facing Mr. Lin later."

"..."

in the office.

Lin Feng, He Hua, and Zhao Mingzhi were all sitting there, chatting about the static verification test of the whole machine. Zhao Mingzhi said, "From the time point of view, the third stage of the static verification test should have started."

"Boss, do you think we can successfully pass the third phase of the static verification test?"

Lin Feng did not answer directly, but asked rhetorically, "What do you think, can you pass it in one go?"

Zhao Mingzhi replied, "I really don't have much confidence in this. After all, it is 150% of the design load, which is too much. If it is 120% of the design load, I am somewhat sure."

He Hua said, "According to my investigation, there is no domestic record of successfully passing the 150% design load static verification test at one time."

Lin Feng smiled slightly, raised his hand to check the time, got up and said, "It's almost time, let's have a technical exchange with everyone."

Several people got up one after another, left the office, and walked into the conference room within 2 minutes. Suddenly, the originally lively conference room became quiet.

It is really Mr. Lin who conducts technical exchanges with us in person!
Seeing everyone looking at him, Lin Feng smiled slightly and said loudly, "I heard that you have encountered some technical difficulties or have some questions during the design process. Today we will talk freely and have a good communication."

Zhao Mingzhi added, "Everyone, don't be cautious, you can ask anything you want, and if someone raises a question that stumps Mr. Lin, I will reward you."

Lin Feng smiled and said, "Only technical problems, other problems are not counted."

Many people laughed because of Lin Feng's humor, and the atmosphere in the meeting room was much more relaxed. Some people were a little nervous before, but they are not nervous now.

The technical exchange started, and a bold designer first talked about the technical problems he encountered in the design process.

In the static verification test plant.

The static load has reached 150% of the design load, and some technicians feel that their heart is about to jump out of their throats, so nervous!
At this time, someone heard that the verification machine under static load seemed to make a slight sound.

Immediately, my heart skipped a beat, the secret path is not good!
