Chapter 227 Hot Lectures

They are the design drawings of structural parts such as engine cover, hatch, and tail boom, and are designed according to the general design drawing of the helicopter structure drawn by Lin Feng himself.

First, he took a look at the design drawings of the tail boom. There were a few minor problems, and Lin Feng pointed them out one by one. Then he looked at the design drawings of the hatch.

It took two or three 10 minutes for Lin Feng to go through the design drawings. More than half of the design drawings had no problems. They were basically the same as the design drawings provided by the system. A few drawings had some problems, and Lin Feng pointed out the problem.

After reading these design drawings, Lin Feng raised his hand to check the time, got up and said, "Let's go, let's go to the training room."

Next, Lin Feng will give a lecture to everyone. This time, he brought a lot of design drawings, all drawn by Lin Feng himself.

A few of these design drawings were purely hand-drawn. At that time, Lin Feng had not used CAD drawings, and most of the others were drawn and printed by computer.

Training classroom.

It was agreed that the class would start at 09:30 in the morning, but it was only around [-]:[-] when all the seats were filled, and the designers who came later had no place and could only stand at the back of the classroom.

"I'm really looking forward to it. Mr. Lin will give us a lecture in person."

"The last time I talked about the structural layout and design of this armed helicopter, what will I talk about this time?"

"."

There are two or three hundred people in the classroom, you say something, I say it, it seems very lively, there are people outside the classroom trotting all the way with notebooks, and some people simply move the chairs over.

conference room.

Lin Feng finished reading all the design drawings, raised his hand to check the time, and said loudly, "Come on, let's go to the training classroom."

A group of people walked into this large training room with Lin Feng in a crowd. The lively and noisy classroom quickly quieted down, and everyone sat upright, ready to listen to Lin Feng's lecture. This time, Mr. Lin will tell everyone something.

Zhao Mingzhi and Li Guangshu also sat down, opened their notebooks, and took out their pens. Like everyone else, they are serious students from now on.

Lin Feng stood on the podium and said loudly, "Today I will mainly tell you about the design of the helicopter's coaxial reversing dual-rotor system. Tang Long will hang up the design drawings."

This time, they could bring more than [-] design drawings, which surprised Zhao Mingzhi and others. They had already called the boss for being amazing, and he actually drew so many design drawings by himself.

Tang Long and Chen Wei hung up the design drawings of the coaxial counter-rotating dual-rotor system. There are a total of two design drawings, which are fully displayed in front of everyone.

At this time, many people rushed over one after another. There were many people outside the window and the corridor.

Seeing this, Lin Feng smiled helplessly. He couldn't even imagine that so many people came after hearing his lecture.

"Comrades, in the next week, I will come here basically every day, half a day at least, or a day at most. In addition to telling you about the design of the coaxial reversing dual-rotor system of this helicopter, I will also tell you about the transmission system, deceleration system, avionics system, etc.”

"The focus will be on the design and development of the avionics system. This will last about three days. Now I will talk about the design of the coaxial counter-rotating rotor system. Other designers can do their own design work, and there is no need to crowd here to listen."

Yes, it is not engaged in the design and development of power system, there is really no need to crowd here to attend lectures.The coaxial counter-rotating dual-rotor system is part of the power system of the helicopter.

How did you know that everyone's happy laughter sounded in the classroom.

"Mr. Lin, although I am not engaged in power system design, I also want to hear about the design of the coaxial contra-rotating dual-rotor system."

"Mr. Lin, the main reason is that you speak so well. Every time I listen to your class, I feel that my design skills have improved a lot."

"I don't care, anyway, I'm going to squeeze here to listen to Mr. Lin's lecture."

"Mr. Lin gave lectures for a few days, and I insisted on listening for a few days."

"."

All the designers said this, upon hearing these words, Lin Feng smiled and said loudly, "Director Zhao, we need to prepare a bigger training room this afternoon."

The current Leihuo Helicopter Design Institute is in good condition. It not only has complete laboratories, but also has many training classrooms and conference rooms. The largest training classroom can accommodate 500 to [-] people to attend lectures.

Zhao Mingzhi was full of apologies, "Boss Lin, it's because we were not prepared enough. We thought that this training room, which could accommodate more than 200 people, was big enough, but we didn't know it was far from enough."

Lin Feng said, "Change to a bigger training room in the afternoon, everyone calm down, and we will start the lecture."

Gradually, the classroom became quiet.

Lin Feng began to tell everyone about the design of the coaxial reversing dual-rotor system of this heavy-duty armed helicopter. He not only combined the two general design drawings in front of him, but also some details and specific designs. Lin Feng took chalk on the blackboard Draw a schematic diagram of the design results and a schematic diagram.

Everyone listened carefully, paying attention to each of them, and the time passed quickly.

From ten o'clock in the morning to twelve o'clock, it seems to have passed in a flash.

Lin Feng put down the chalk in his hand, and said loudly, "That's all for this morning, and we will continue to talk about the design of the coaxial contra-rotating dual-rotor system at two o'clock in the afternoon."

After speaking, Lin Feng walked out of the classroom accompanied by Zhao Mingzhi and others.

boom!
The classroom was completely lively.

"Niubian, Boss Lin's speech is so good, it's too detailed."

"I think such a coaxial counter-rotating dual-rotor system design is too scientific and creative."

"If you want to apply for a patent, you can apply for at least a dozen patents for the optical coaxial reversing dual-rotor system."

"How did Lin always come up with such a design, genius, it's really a genius design."

"."

Most of the people didn't leave, even though it's time for lunch, but lunch is nothing, everyone is immersed in this advanced design.

Among these attendees, there are at least 30 to [-] foreigners. They are all from the former Soviet Union. They are mainly from the Miri Design Bureau or the Mokafu Design Bureau. Several of them are experts in helicopter design. .

At this moment, their hearts are full of shock!

It never occurred to them that their new boss had such high technical attainments, and the design idea of ​​such an advanced coaxial counter-rotating dual-rotor system came from Lin Feng.

They knew that such a design was more scientific and advanced than the Ka-50's coaxial reversing dual-rotor system, so they had a little expectation in their hearts, to complete the design as soon as possible, and watch this armed helicopter be manufactured as soon as possible.

At [-] o'clock in the afternoon, a new classroom was replaced. This brand new classroom has a larger area, more seats, and more complete facilities. Not only are there microphones and speakers, but also a slide projector, and even the black border is bigger.

Zhao Mingzhi thought to himself, this classroom can accommodate 500 to [-] people, which should be enough. Obviously he underestimated the charm of Lin Feng's teaching, and also underestimated the enthusiasm of the designers to listen to the class. Such a large classroom is actually full.

Not only were the seats full, there was no vacant seat, and even people at the back of the classroom moved stools to sit there and listen to the lectures. Fortunately, there were no more people lying on the window sills or standing outside the corridors.

For a whole afternoon, Lin Feng gave everyone the design of the coaxial reversing dual-rotor system, two hours in the morning and three hours in the afternoon, a total of five hours.

Basically every designer took at least [-] to [-] pages of notes. In addition to a large number of written records, there were also quite a few design sketches.

These design sketches will be of great help to the specific design work in the future, even Zhao Mingzhi is the same, he will record all the design sketches that Lin Feng draws with chalk on the blackboard in his notebook.

Lin Feng did what he said, and sure enough, he came to Leihuo Helicopter Design Institute early the next day. He started to talk about the design of the transmission system of this heavy-duty armed helicopter at [-]:[-] in the morning, and talked about the design of the deceleration system in the afternoon.

On the third day, I started to talk about the design of the helicopter's avionics system, mainly talking about the design of the observation/fire control system.

This system mainly consists of five parts: laser rangefinder and calibration instrument, forward looking infrared system (FLIR), gunner-specific optical direct aiming instrument, daytime television camera and laser calibration instrument, all installed in a nose-mounted dual-axis The rotating tower of the stabilization system enables the crew to aim at the target smoothly during intense tactical movements, and the use of FLIR greatly increases the night combat capability.

This is the point of the story.

Lin Feng gave a very detailed description. He not only showed everyone the general design drawing he had drawn, but also explained part by part, such as schematic diagrams and structural diagrams. He even drew a lot on the blackboard with chalk.

Lin Feng plans to talk about the design of the observation/fire control system for three days, because this system has high technical content and advanced functions. If you don’t explain it in detail, it will be very difficult for everyone to design.

The five parts are explained in detail one by one.

On the first day, I only explained two parts. In the morning, I talked about the design of the laser rangefinder and calibration instrument, and in the afternoon, I explained in detail the design of the gunner's special optical direct collimator.

It wasn't until six o'clock in the afternoon that Lin Feng finished his lecture and walked out of the large classroom under everyone's reluctant eyes.

"I'm not dreaming, pinch me quickly."

"I also have a feeling of dreaming. The avionics system design of our heavy armed helicopter is so advanced, it's unbelievable!"

"I don't know the level of the American Longbow Apache's avionics system, but I think the technical content and comprehensive performance of our heavy-duty armed helicopter's avionics system must be higher than that of Apache."

"Please be more confident and remove the word 'possible'."

"."

The hundreds of designers who attended the class were simply blown away. They only listened to the design of the avionics system for one day, and their reactions were huge.

The same is true for those experts from the former Soviet Union. After listening to the lecture for a day, they are still stunned. The impact brought by what Lin Feng said today is too great.

In the evening, Lin Feng did not stay in the provincial capital, but returned to his big villa.

On the car back, Lin Feng received a call from Zhong Zimin.

He went to the capital for several days, reported the heavy armed helicopter to the leaders comprehensively and in detail, and now returned to the Phoenix factory.

"Mr. Lin, I heard that you have been teaching everyone at the Helicopter Design Institute these days."

"Yes, the design of this heavy-duty armed helicopter is in full swing, and we must give you some technical guidance."

Zhong Zimin said in admiration, "For a boss like Mr. Lin who understands technology and has such high technical attainments, you are No. 1 in the whole country."

Lin Feng smiled modestly, and then asked, "Have you returned from the capital?"

"I came back this evening." Zhong Zimin said, "I'll come to your place tomorrow to sit down and let's have a chat."

"Yes, very welcome." Lin Feng said.

Knowing that the other party didn't just come and sit for a while, and probably had something to tell him, Lin Feng would readily agree.

After answering Zhong Zimin's call, Lin Feng called Zhao Mingzhi. He was temporarily unable to teach everyone tomorrow morning due to something, and waited for his call in the afternoon.

The next day.

Zhong Zimin arrived at Leihuo Technology Industrial Group early in the morning and walked into Lin Feng's big office. At this time, it was not until 08:30 in the morning.

"Mr. Zhong, you're here so early."

"I didn't go to Phoenix Factory, I came directly to you."

The two met, exchanged a few pleasantries, sat down on the sofa in the reception area, and chatted while drinking tea.

Zhong Zimin briefly talked about his trip to the capital, and then said, "The leaders are very satisfied with this heavy-duty armed helicopter, and their expectations are very high. I hope you can develop it as soon as possible."

"If there is any difficulty, just raise it, and I will convey it to the higher-ups on my behalf, and I think the higher-ups will try their best to solve it."

Lin Feng really has some things that need help from above.The first is the issue of talents. The Group is allowed to recruit talents from various aviation manufacturing enterprises and research institutes across the country, and the Group is allowed to recruit talents from universities and colleges like a state-owned enterprise.

The second is the treatment of talents, as well as the placement and settlement of overseas talents.The third is
Lin Feng made several requests, but none of them were excessive, and he didn't take the opportunity to ask for prices. Zhong Zimin recorded them one by one in his notebook.

"Boss Lin, I think the higher-ups will fully consider your requirements. In addition, what requirements do you have regarding the design of the weapon system of this heavy-duty armed helicopter?"

Even if he doesn't mention this matter, Lin Feng is ready to mention it.

"In terms of weapon system design, 100% domestic weapons must be used. Based on this heavy-duty armed helicopter, relevant units can cooperate in the design and development of advanced weapons. They include various types of missiles and rockets carried by this helicopter, including 30mm single-barreled chains. Cannon, wait."

It is of course the best for other units to undertake the design and development tasks for the design of the weapon system. Leihuo Technology Industry Group is a little easier. After all, professional people do professional things. If Leihuo Technology Industry Group is really responsible for designing and developing It is not very big, but it will consume a lot of manpower and material resources, and there is no special talent for the design and development of weapon systems for the time being.

The military is different. They not only have specialists in weapon design and development, but also related research institutions, laboratories, and testing grounds.

Isn't it nice to raise design requirements by yourself and let others implement them.

Zhong Zimin said: "I will report to the higher authorities that the weapon design and development of this armed helicopter should indeed be started."

After the two chatted for a while, Zhong Zimin revealed, "You have already started the design and development of heavy-duty armed helicopters. The military has always wanted to start the development of dedicated medium-sized armed helicopters. It is estimated that this project will be launched soon."

As early as two or three years ago, China began the design and demonstration of special-purpose medium-sized armed helicopters, and the pre-research of key technologies, etc. Some key technology pre-research has also achieved success and breakthroughs, such as the pre-research of composite material rotors.

Of course, Lin Feng knew about this special-purpose medium-sized armed helicopter. In later generations, it was quite well-known, and it was an important role for domestic armed helicopters.

In China, a helicopter design institute.

Qian Bo came back from the capital, and this time he went to Beijing mainly to start the design and development of special-purpose medium-sized armed helicopters.

He never expected that this work would start so suddenly. He originally thought that it would take at least two or three years to start officially. Although some key technologies have been broken through, there are still some key technologies that have not been overcome.

He's under a lot of pressure right now.

After returning, he sat in the office, frowning and smoking while thinking about the design and development of this special armed helicopter. He smoked several cigarettes in a row before picking up the phone and ordering a meeting.

Qian Bo knew that the military's sudden early start of design and development work was mainly related to Leihuo Technology and Industry Group, because their heavy-duty armed helicopters had already started design and development in an all-round way, and their positioning was very high.

When he was in the capital, he was fortunate enough to see a copy of the design and technical outline of this heavy-duty armed helicopter. Because the document was highly confidential, he could not copy it or transcribe it, so he could only browse it roughly.

Sure enough, it is the world's top level heavy armed helicopter.

As a professional, Qian Tao knows that if this heavy-duty armed helicopter is successfully developed, it will definitely be ahead of the American Longbow Apache, and our domestic armed helicopters will immediately reach the forefront of the world.

People are sure to produce the world's top heavy-duty armed helicopters, but what about us, we can produce world-class special-purpose medium-sized armed helicopters.

Gradually, he also gained some confidence. At least the turboshaft engine was ready-made, so he used the LH1500 turboshaft engine from Leihuo Technology Industrial Group, and the composite material rotor was also successfully developed.

Are you going to visit Leihuo Technology Industrial Group and engage in technical exchanges?

If you can learn a little technology from them, it is estimated that it will be of great help to this professional medium-sized gunship, or, please invite Mr. Lin to come and tell you about the design of the gunship.
Qian Bo thought a lot, until the knock on the door interrupted his thoughts.

Show me the official, remember to vote monthly.
