Start with the aviation industry

Chapter 230 This is the confidence
Luo Pingfan thought a lot.

For example, how is Mr. Lin's expertise in missiles?
He will talk to me about something, what is drawn on the design drawings, how is the quality...

About an hour or so, the minibus arrived at the gate of Leihuo Technology Industrial Group, a magnificent gate with gilded and eye-catching characters.

Leihuo Technology Industrial Group
Rayfire Aero Engines

"Here we are!"

"This is Leihuo Technology Industrial Group. Look at those two buildings, how beautiful they are. It is estimated that there are such buildings only in coastal areas."

"Finally about to see their turboshaft!"

"..."

Luo Pingfan finally came to his senses, looked at the big gold-plated characters of Leihuo Technology Industrial Group, took a deep breath, and said loudly, "Wait a while to visit the aero-engine manufacturing site, I won't emphasize discipline , I believe everyone understands."

"Don't worry, we both know."

"We just watch with our eyes, we don't record, let alone take pictures."

Luo Pingfan nodded, feeling relieved, and the car stopped in front of the office building of Leihuo Technology Industry Group.

"Experts, welcome to Leihuo Technology Industrial Group."

There was a receptionist waiting at the entrance of the building. They were very enthusiastic. Everyone got out of the car and walked into the building under the guidance of the receptionist.

As soon as you enter, you will see a spacious and bright hall. The marble tiles on the floor are smooth enough to illuminate people's shadows, and the huge imported crystal lamp above your head is very magnificent.

Seeing this, someone thought in their hearts, it is indeed Leihuo Technology Industrial Group.

Through the elevator, everyone arrived at the top floor. Most of them took a break in the reception room, drank tea, listened to the introduction about Leihuo Technology Industry Group, and then visited the production site of Leihuo Aero Engine Company under the guidance of the staff. Take a look at this turboshaft engine under construction.

Under the leadership of Ding Haixia, Luo Pingfan arrived at the door of Lin Feng's big office. She raised her hand and knocked on the door, and said loudly, "Boss, Director Luo has arrived."

Lin Feng's voice came from inside, "Please come in."

Ding Haixia pushed open the door of the office and invited, "Director Luo, please come in."

Luo Pingfan walked into this big office, and before he had time to marvel at the luxury of this office, his eyes were soon attracted by several large color pictures hanging on the wall.

That is the LH1500 turboshaft engine!
That's a transport helicopter, that's a heavy gunship!
Soon, his eyes fell on Lin Feng, and the look of surprise almost showed on his face. He knew that Lin Feng was young, but he didn't expect to be so young.

Boss Lin looks too young!

Lin Feng was very enthusiastic. He got up and walked over, and stretched out his right hand actively, "Director Luo, welcome, welcome to our Leihuo Technology Industrial Group."

Luo Pingfan held Lin Feng's right hand tightly with both hands, "Boss Lin, I'm interrupting your work."

The two exchanged some polite greetings, and sat down on the sofa in the reception area under Lin Feng's warm invitation. They chatted while drinking tea.

Under Lin Feng's inquiry, Luo Pingfan introduced the situation of their missile institute, focusing on the types of missiles they designed and developed, including air-to-surface anti-tank missiles.

These types of missiles are all good, either reaching the world-class level, or already close to the world-class level, but if they are used as the missiles carried by the world's top heavy-duty armed helicopters, they are still not enough.

Lin Feng said, "Director Luo, users have high expectations not only for our heavy-duty armed helicopter, but also for its weaponry."

Luo Pingfan agreed, "Yes, after all, this is the world's top-level heavy-duty armed helicopter."

Lin Feng said, "Do you have any plans for the missile design and development of this heavy armed helicopter?"

Luo Pingfan, "To be honest, not yet, we are under a lot of pressure."

Lin Feng stood up and said, "I have an idea, and I drew some design drawings by myself. Director Luo, come and see how these drawings look."

Next door is the drawing room, with an area of ​​tens of square meters, with a large table in the middle, on which are the design drawings drawn by Lin Feng himself.

Luo Pingfan followed Lin Feng into the drawing room.

Lin Feng first unfolded the general design drawing of the missile, and then said, "In fact, I have some considerations about what kind of anti-tank missile this heavy armed helicopter will use in the future. I have drawn some design drawings in the past few days, and this is the general design drawing of the missile. "

Isn't it just the general design drawing of the missile?

Very professionally drawn.

Luo Pingfan is an expert in this field, and he knew at a glance that this blueprint was not made up. Immediately, hope rose in his heart, and he looked at it seriously.

"Mr. Lin, can you tell me about this missile in detail?"

"Of course." Lin Feng said, "First of all, we have to consider the versatility of the missile. Not only can it be used on future armed helicopters, but it should also be able to be used on other equipment or other weapon systems."

"It is also a missile that can be launched from sea, land, and air to attack armored mobile targets on sea or land, and it should have the advantages of long launch distance, high accuracy, and great power."

Lin Feng first introduced the design idea of ​​this missile in general, and then talked about the design of the missile in detail.

"If I were to design this missile, it would adopt a modular design. Different guidance methods and different seekers could be selected according to tactical needs and weather conditions. However, laser semi-active homing is usually used for guidance."

Pointing to this general design drawing, Lin Feng introduced, "The projectile is stick-shaped, with two sets of control surfaces. The first group is located at the rear of the projectile, with four symmetrically installed pieces. The wingspan is not large. The second group is located at the front of the missile body, smaller in size and square in shape. There is a laser beam receiving window in the head, which is transparent and the internal device can be seen.”

Luo Pingfan listened carefully.

Gradually, the originally calm face was no longer calm, and there was a turbulent storm in his heart. More than once, he said in his heart, if he didn't see it with his own eyes, who would believe that Mr. Lin's professional level in missile design is so high.

After talking about the overall design of the missile, Lin Feng laid out the general principle diagram and explained it. Finally, he spread out the design drawings of several key components and gave a serious explanation.

Luo Pingfan felt like he was dreaming.

With these blueprints and Lin Feng's professional explanation, all the obstacles in their way disappeared. Now, he has full confidence to lead everyone to design and develop this missile.

Boss Lin is awesome!

Luo Pingfan seldom admired anyone, but at this moment he cast all his admiration for Lin Feng. While looking at Lin Feng with admiring eyes, he took notes carefully.

More than two hours.

After finishing what was to be said, Lin Feng solemnly handed over the design drawings to Luo Fanfan, "I will leave the design drawings to you. The specific design and development must be done by you. I will wait for your good news."

Luo Pingfan said a little excitedly, "Boss Lin, don't worry, we will definitely design this missile, and it must be before the prototype of this heavy armed helicopter."

Although the missile is complex, compared with the more complex heavy-duty armed helicopter, the workload is much smaller, and the development cycle should be much shorter. Now with these design drawings and Lin Feng's explanation just now, Luo Pingfan is full of confidence .

Everything seemed to be relaxed, the pressure in his heart disappeared, Luo Pingfan seemed to be a different person, and he talked more.

After sitting down and chatting for a while, he thanked him again, and then left emotionally with these design drawings. He has only one thought now, to start the design work of this missile as soon as possible.

Xiang Xiaojun, Zhu Yingwei, and several other design experts visited Leihuo Aviation Engine Manufacturing Factory, and saw huge workshops, advanced numerical control equipment, and the details of each manufacturing process of the LH1500 turboshaft engine. Component.

In the huge aero engine assembly workshop, they also saw the LH1500 turboshaft engine in the assembly.

After lunch, they were ready to leave.

Careful people found that Director Luo seemed to be in a good mood, he was no longer stressed, and his brows that had been slightly frowned for the past few days were relaxed.

Xiang Xiaojun asked curiously, "Lao Luo, it's like a different person after you went to Mr. Lin's office. I can't tell you the details, but I can clearly feel that your mood is much better."

Luo Pingfan smiled heartily, "I didn't expect Mr. Lin's technical attainments to be so high. He gave me a lot of guidance on the design of the missile. Now, I am full of confidence in the design of this missile."

what!
This is impossible!
Xiang Xiaojun thought he heard it wrong, and his eyes seemed to say, "Lao Luo, you are joking with me."

It is understandable for him not to believe it, because he himself is an expert in missile design, and he is confident that there will not be more than one person in the country who surpasses him in missile design, but Lin Feng will definitely not be among the few people. .

"Old Luo, is Boss Lin's technical level really high?"

"Tall, very tall, just outrageously tall." Luo Pingfan said with a look of admiration.

They flew back in the afternoon, and as soon as they got to work on the first morning, Luo Pingfan called his assistant over, "Xiao Zhu, please inform me that a meeting will be held at ten o'clock in the morning, and all people above the design supervisor will participate. Design work on the missile began in full swing today."

Zhu Yingwei said tentatively, "Leader, you already have a design plan."

It must have been there, and it is extremely clear. There are several design drawings in his bag, which are neatly folded and kept by Luo Pingfan like treasures.

After watching Zhu Yingwen go out, Luo Pingfan took out the technical requirements issued by the military and looked relaxed.

The military's requirements for this missile are very high. Luo Pingfan used to feel a lot of pressure. Now there is no pressure, only self-confidence. Seeing the technical requirements and parameters of each item, there is no pressure anymore.

The military's requirements for this missile are as follows:

Launch weight: less than 60 kg
Warhead weight: more than 10 kg
Warhead charge: greater than 8 kg of high-energy mixed explosives, equipped with a trigger fuze
Reliability: higher than 95%
Conditions of use: all-weather use, can lock the target in the smoke, rain and fog on the battlefield
Penetration thickness: greater than 1500mm
Maximum range: more than 10 kilometers
Storage period: more than 10 years

Such a high requirement is difficult, simply too difficult. Luo Pingfan thought it was a huge challenge before, but now he doesn't think so at all.

Mr. Lin said that according to these design drawings, this missile fully meets the military's requirements for long range, accurate shooting, high reliability, and high power.

For example, the maximum range can exceed 15 kilometers, and the reliability exceeds 95%. There is no problem at all. The high-energy mixed explosive with a warhead of more than 8 kilograms is very powerful, and the armor-piercing ability exceeds 1500 mm. There is no problem.

So what are you waiting for, hurry up and start the specific design work, and get this missile out earlier.

Luo Pingfan held a design kick-off meeting, and uncharacteristically acted as the chief designer of this missile himself, while Xiang Xiaojun only appointed a deputy chief designer.

Leihuo Helicopter Design Institute.

The current conditions are completely different from those in the past. In the past, hundreds of designers were crowded into one building, but now there are not only design buildings with more than [-] floors, but also various laboratories, and even their own static tests. plant.

Now, a static test is being prepared.

At the site of the static test plant, Zhao Mingzhi and Li Guangshu were there, and there were several experts and some key technicians beside them.

One of the more important parts of this transport helicopter, the bracket for the steering booster, is going to be subjected to the static test. It is made of magnesium-aluminum alloy, has a relatively complicated structure, and is a stress-bearing part.

Whether it will work normally in the future cannot be determined without testing.Originally, there were many important parts for the static test, but Mr. Lin said that all design verification should be simplified, so a large part of the parts were cut off, leaving only a few parts including the steering booster bracket .

"Mr. Zhao, everything is ready."

This is a technician in charge of the static test. He walked over quickly and reported to Zhao Mingzhi the preparations for this static test.

Zhao Mingzhi waved his hand and said, "Start the static test."

The static test will start immediately.

The test equipment is started. This set of test equipment and test tooling are designed by Leihuo Technology Industrial Group. After the start, it can be seen from the instruments and meters that the force loaded on the steering booster bracket is slowly increasing.

The entire static test plant seemed quiet, only the sound of the test equipment working, and after a while, a loud voice sounded.

"Loaded to [-]% of design load!"

That is two-thirds of the design load.

Hearing this sound, everyone looked at the yaw control booster bracket under static load. Some people thought in their hearts that the parts looked normal, and they wondered if there was any deformation that could not be seen by the naked eye.

Two-thirds of the static load was loaded for 10 minutes, and then the parts were unloaded. Several experimenters unloaded the parts and put them on the inspection platform not far away.

Everyone gathered around.

"It looks like there's nothing wrong with it."

"No problem is normal, after all, it is only two-thirds of the static load."

The visual inspection was correct, and several technicians immediately started to measure the relevant dimensions. After some measurements, they found that there were no changes in several key dimensions, which meant that there was no problem with this part.

The static test continues.

This time, the loading time is still 10 minutes to [-]% of the design load.

During these 10 minutes, the scene has been relatively quiet, but if you look closely, it is estimated that a few people are a little nervous. After all, it has reached [-]% of the design load, in case something goes wrong.

Once a problem occurs, it means that there may be a problem with the design, and the design must be redesigned, which consumes manpower, material resources and time.

"Old Zhao, you said that after loading to [-]% of the design load, will there be any problems with our steering booster bracket?"

Zhao Mingzhi shook his head slowly, "I believe there shouldn't be any problems with our design."

Rather than trusting his own design, it is better to trust Mr. Lin, because the design of this transport helicopter was almost completed under Lin Feng's hands-on guidance. Many key and important parts were designed by Lin Feng himself, including the course control. Design drawing of booster bracket.

As soon as the 10 minutes were up, the parts were unloaded immediately, and the relevant inspections started again. This time, it was different from the two-thirds of the design load. In addition to visual inspections and dimensional inspections, instrument inspections were also used.

There is no problem with the appearance inspection!
Size check is no problem!
Instrument checks are no problem either! ! !

Some young designers even cheered up, everything is normal, indicating that the design is very successful, at least there will be no problem with this part under 100% design load.

It is also necessary to know how much load it can withstand, so the static test will continue.

This is the third static test, and the load continues to increase until it reaches 100% of the design load.

105%, 110%, 115%
The whole site was tense, and many people worried that the parts would be deformed under such high-strength loads, and even worried that the parts would crack or break with a "snap".

The static load reaches 130%!

Someone even looked at Zhao Mingzhi, is it possible to continue to increase the load? The design load of 130% is already very good, so there is no need to continue to increase it.

135%, 140%, 145%
The static load continued to increase, and some people even tensed up their entire nerves, worrying that the parts would suddenly break with a "bang".

Added to 150% of the design load, which is 1.5 times the design load, and finally stopped.

The safety factor of the design is 1.5, which is 1.5 times the maximum design load that this part can withstand in theory, which is still 10 minutes.

These 10 minutes seemed extremely long, and some people even clenched their fists, counting silently in their hearts, hoping that the time would pass sooner.

As if an hour had passed, 10 minutes finally came, and the parts began to be unloaded, and then the parts were unloaded under everyone's eyes, and placed on the inspection platform not far away again.

Various inspections have started again, this time, will there be any problems!
