In the multi-media classroom.
On the clear multi-media screen, the concept map of the gas turbine engine was spinning, and the data listed next to it was eye-catching.
Chu Feng stood on the podium with a serious expression and said meticulously,"Everyone here is an expert in this field, so I won't explain the basic concepts. First of all, I want to talk about why our country has been researching for 30 years and spent 200 billion yuan, but we still haven't developed an autonomous engine.”
When Chu Feng finished speaking, many of the elders below the stage lowered their heads in shame. The country had high hopes for them, but they had failed to live up to the country's high hopes. They had failed to develop a domestic engine, which made them feel ashamed. Actually, they didn't have to do this at all.
" The first reason is the limitation of basic industries.”Chu Feng had seen everything that had happened below the stage, but he did not say much. Instead, he continued to preach,"Our country's industrial base is relatively weak compared to the western countries, especially in terms of new materials and high-temperature materials.”
"As we all know, the material requirements for engine design are very strict. The key components such as the air chamber, combustion chamber, and turbine all include extremely high design and manufacturing technology. Our cooling technology, machine tool manufacturing, and pressure-resistant materials can't pass the test. Even if they pass, they can't reach the level of mass production. Some people say that they want to import it, but I want to ask which industrial country will export this material?”
"Yeah, I know…"
"Yes."
The elders nodded. They understood what Chu Feng was saying. In the process of developing domestic engines, the biggest limitation was the material limit. If the mass production materials were not up to standard, the qualified materials could not be mass produced. Even if the engine was developed, it could not be installed. It was useless.
" The second point I want to say is that both our country and other industrial countries have fallen into a misunderstanding.”Chu Feng threw out a heavy bomb and ignored the commotion below the stage. He said seriously,"I once spent a month analyzing the LM2500 and the so-called domestic Taihang engine. I was surprised to find that they have a lot in common.”
"Indeed, our country's industrial process started relatively late. In the beginning, our strategy was to buy it from abroad, disassemble it, analyze it, and then design it ourselves. To put it bluntly, it was to improve or modify other people's technology, then change the name and label it as domestic. This vicious model continued until the beginning of the century, when purely autonomous things came out. However, this model was still applied in some fields, such as engines.”
"This is the Taihang engine that our country has independently manufactured.”Chu Feng switched the images on the screen and said,"The 606 Institute of the China Aerospace Research Institute spent 20 years developing this engine and has already implemented it. I think some of you should also be involved in this project.”
The audience nodded, and Chu Feng switched to the screen again." This is the L2000 engine that Big Bear Nation sold us. Taihang was developed based on it, right?”
The similarities between the two engines were listed on the screen. The core technology was almost identical.
"This is the mistake we have made. We rely too much on imitation and have nothing of our own.”Chu Feng sighed." You can't be blamed for this. It's your habitual thinking that has restricted your ideas. If you used 200 billion on innovation instead of improvement, the results might be much greater than now.”
"This…"
"Yes, I am."
"We were too old and muddle-headed. We were too stubborn and stuck to a dead end.”
"Actually, we should listen to the suggestions of young people. Their minds should be more active.”
“……”
The elders sighed and pondered.
The era of import dismantling imitation = independent research and development should be over. China's scientific research level, scientific research strength, and scientific research talents were actually not inferior to developed countries in Europe and the United States. However, in the subconscious mind of people, they still thought that foreign things were better. It was just like how some people thought that the moon abroad was rounder than the moon in China, and that the sh * t abroad was more fragrant than the sh * t in China.
After a while, the elders calmed down. Chu Feng suddenly raised his head and blinked his innocent eyes."I'm a little thirsty. Can someone make me a cup of tea?”
“……”
“……”
“……”
"How about…I go?" A little old man in his fifties stood up. His skin was dark and his eyes were shining. He was the youngest among this group of old scientists, but his achievements were not small. He had won a national scientific achievement award and participated in the improvement of the first aircraft carrier, the Varyag.
"No, no, I'll go. You sit.”
Xu Lei held it in for a long time and could not sit down anymore.
"Alright, then you can go." The little old man immediately sat down.
Xu Lei was speechless.
Chu Feng glanced at him and said embarrassedly,"Thank you, Principal Xu. Don't break the tea and don't use the disposable cup. First, use the 80-degree water to soak it three times, then use the 100-degree water to soak it.”
" Mm…" Xu Lei left with a stomach full of anger.
"Alright, there are no outsiders now.”Chu Feng chuckled. It was better to talk about key technologies like engines to professionals. If they leaked the information, it would be difficult to explain it to the higher-ups.
"Everyone has seen the data of this engine. Do you realize that the engine I developed is completely different from what you have seen before? Because I didn't imitate or refer to any existing engine. Instead, I started from scratch and developed it step by step from the functions and functions of the engine I imagined.”
"Does it have a sample?" An old man asked impatiently.
Chu Feng nodded." Yes, but due to some special reasons, I destroyed it.”
In order to prevent the sample gas turbine from falling into the hands of the M Nation, Chu Feng personally destroyed it.
"Then…what about its performance?" The old man's expression turned from pleasant surprise to gloom.
"I have its performance test here. Because of the material, its performance is only 80% of its theoretical performance.”
Da!
The mouse clicked.
The performance of the prototype engine was displayed on the screen.
"This…"
"Heavens…"
"Tsk tsk tsk…"
"I can't believe it! I can't believe it!"
"Is this…true?"
There was a commotion in the classroom.
