Genius of the Rules-Style System

Power Engineering Laboratory.

The people in the project team patiently disassembled the prototype. They were already very skilled in the disassembly work. Several professional workers and engineers had no experience in disassembling the entire machine, but they had experience in installing two or three prototypes and were familiar with each component. Learn more.

The prototype is a product designed for experimental research and display. Occasionally, parts will be replaced, so it becomes much easier and smoother to disassemble the whole machine into several parts and then disassemble it in detail.

While the work was being carried out, several people were also discussing. An engineer named Zhou Qing said, "Why did Academician Zhao decide to dismantle the prototype? And dismantle all of it? If it is for research, look at the design Wouldn’t it be better to take apart a certain part?”

"Who knows? Don't they all say it? The ideas of geniuses are different from those of ordinary people." A worker who was tightening nuts joked.

That's not a compliment or a self-deprecation, but a bit of a joke.

Yuan Haitao heard a few people talking from a distance, and came over and said, "It's really a pity that the whole prototype was dismantled. But I thought about it carefully and found that it has problems all the time. Maybe it's because of something inside." Some parts are improperly designed and installed improperly. If we test each part, we may be able to find the problem."

"This is also an opportunity. If it were at the base, it would definitely not be demolished like this."

"Right."

"Captain Yuan is right."

"Just do this. Anyway, there's nothing going on here. We're all just hanging around this prototype."

"We still have to wait for the machine to be transferred..."

Yuan Haitao talked about the next work, and then reminded him, "Don't keep talking about Academician Zhao and Academician Zhao. Who is that person? A top mathematician, the top scholar in the world. It has been explained above, and everything must be obeyed. Our team cannot be as good as Academician Zhao alone. No matter how old Academician Zhao is..." He stopped immediately and said, "Anyway, it's best not to talk."

Several people nodded as they listened.

Although Yuan Haitao told him not to talk about it, people are prone to gossip and like to talk about things they don't understand.

Apparently.

This time the disassembly work of the prototype was something they didn’t understand. They considered themselves to be ‘professionals’ and felt a bit like they were being told what to do by ‘laypersons’.

Even if a layman is a top mathematician, what does it have to do with engine design and manufacturing?

…

The disassembly work of the prototype is coming to an end.

Most of the work involves copying parts and installing the newly shipped inspection and auxiliary machines, which also makes the operation room very busy, because some of the machines are very heavy and require the help of the armed police at the door. Come be a porter.

Zhao Yi is here.

Zhao Yi came here almost once a day. Because he was doing dismantling work, installing machines, etc., he basically couldn't help. He only stayed for a while and then left.

This time he did not leave, but asked Yuan Haitao about technical issues. The focus of the discussion was the combustion chamber.

The combustion chamber is the inner part of a turbine engine that provides power.

There are several types of aviation turbine engines, namely turboprop engines, turbojet engines and turbofan engines. The highest performance among them is the turbojet engine. When loaded on a fighter aircraft, it can easily provide supersonic power. The highest power can make the fighter aircraft fly The speed exceeds Mach 3, which is three times the speed of sound.

However, the fuel consumption of turbojet engines is very high, and the higher the power the engine provides, the better. There are also many issues such as practicality, fuel consumption, and endurance to consider.

A fighter jet can reach a speed of Mach 3, but each flight consumes a lot of fuel. Not only does it consume a lot of fuel, but high fuel consumption definitely corresponds to low endurance, and the maximum flight distance will be severely limited.

That's why turboprop engines and turbofan engines appear.

A turboprop engine can be understood as a turbojet engine with a propeller in front. The engine is dominated by the pulling force (thrust) generated by the propeller. The thrust generated by the jet is very small, accounting for only about one-ninth of the propeller. The thrust of the turboprop engine The advantage is high efficiency at low speed, suitable for transport aircraft, maritime patrol aircraft, etc. Due to the large rotating area of ​​the propeller, it will produce a lot of resistance during high-speed flight, so the turboprop engine is not suitable for high-speed flight.

A turbofan engine is between a turbojet engine and a turboprop engine. It can be understood as a fan installed in front of the turbojet engine. It can provide good power and can support a speed of 1,000 kilometers per hour. It also greatly reduces the engine's load. In terms of fuel consumption, the disadvantage is that the engine structural design and technology are too complex.

The Kunlun engine is a turbofan engine.

The reason why the country attaches great importance to it is because the research and development technology is comprehensive. For example, with the foundation of Kunlun engine technology, we can easily take out part of it to develop the latest turbojet engine, allowing China to independently produce supersonic fighters, and also The principles of propellers can be combined to expand and develop new turboprop engines for use on transport aircraft and patrol aircraft.

Although the Kunlun engine is the most technically complex turbofan engine, the core of the power it provides is no different from other types of turbine engines. The most important elements are the combustion chamber and turbine.

Zhao Yi also mentioned the key point when he mentioned the combustion chamber. He asked about the technology related to the combustion chamber.

Yuan Haitao also knew about the combustion chamber design and said with some pride, "Kunlun's combustion chamber design allows the airflow to enter in parallel and gives a certain pressure. The space of the combustion chamber is enlarged and special materials are used to reduce the weight. In addition, , divided and differential fuel supply is also key.”

"Stability is the most important thing. The partial pressure fuel supply and parallel air intake in the design can ensure the stability of the combustion chamber and control..."

Zhao Yi compared the information in his hand with Yuan Haitao's detailed explanation, and almost had a comprehensive understanding of the design and working principle of the combustion chamber. Then he asked, "When can we do the ignition experiment? Let the combustion chamber run. Take a look."

"You want to know the actual parameters?" Yuan Haitao asked doubtfully.

"right."

Zhao Yi nodded and said, "I also want to really see how the combustion chamber works and how the data is collected."

Yuan Haitao said, "This is easy to handle. When the machine is assembled tomorrow, we will mainly make preparations in this area. We can try to run it probably the day after tomorrow."

"good."

It is not a big project to operate a single combustion chamber. The main reason is that it is not easy to provide an auxiliary environment.

For example, simulating high-speed airflow to ensure that the air inlet of the combustion chamber has a high enough pressure requires special machine assistance. There is also the issue of fuel injection, which is definitely impossible to do manually and requires machine assistance.

In addition, data collection is not easy.

How much power the combustion chamber can provide and what the control situation is during the process need to collect a lot of data for measurement.

The team led by Yuan Haitao worked very efficiently. He called Zhao Yi the next afternoon and said that the ignition experiment of the combustion chamber could be carried out that day. Zhao Yi rushed over immediately.

After more than two hours of preparation, the combustion chamber ignition experiment officially began.

Several people were busy around.

Zhao Yi came closer and took a closer look, but it was difficult to see anything from the outside. It was like a diesel engine working. You could only hear the sound and see the wheels turning. The combustion inside could not be seen, and you could only see it. Make an understanding based on the data collected.

He was slightly disappointed, but he still gained something.

The external state of the combustion chamber and the flames ejected from behind can also briefly explain some problems. At least the system recognizes the conditions.

The ignition experiment didn't last long, and it ended in about five minutes.

What follows is busy cooling down, organizing, recording data, etc.

Looking at the busy scene in front of him, Zhao Yi simply stood aside. He really couldn't help much in the past. When everyone was almost busy, Yuan Haitao handed the collected data to Zhao Yi.

Zhao Yi took a careful look and found that there was still a difference between the parameters given.

Yuan Haitao said, "The final parameters were obtained through many experiments. It is normal for the results of one experiment to fluctuate."

Zhao Yi understood.

He thought for a while and said seriously, "Captain Yuan, I have already thought about improving the engine, starting from the combustion chamber. So the focus of our work right now is to improve the design of the combustion chamber."

"Combustion chamber? Is there anything else that can be improved in the combustion chamber?" Yuan Haitao's eyes were filled with confusion.

The main technical core of the Kunlun engine is the design of the turbine, fan blades and overall control. The auxiliary pressure supply, cooling technology and materials are also very important.

The least important of these is the combustion chamber.

Although the combustion chamber also has a "partial pressure zone" technology to ensure the stability of the combustion chamber, in fact, the design and manufacturing of the combustion chamber are much simpler, because the structure is simpler at first, and it seems impossible to improve it.

"I think that in order to improve the engine, we first need a combustion chamber that is more stable, more carefully controlled, and can provide greater energy."

Zhao Yi said very seriously, "The combustion chamber is the core of the engine. Next, we will study together how we can improve it so that the combustion chamber can achieve higher and more stable efficiency."

"……All right."

Yuan Haitao hesitated and did not continue to say anything. He really wanted to see how Zhao Yi 'researched' it.

…

Yuan Haitao didn't quite believe in Zhao Yi's ability, but he still fully cooperated with the work and helped Zhao Yi find a lot of information about engines and combustion chambers, not just turbine engines, but other types of engines, and even aircraft carrier and battleship engines. The information must be confidential to a certain extent, and he came directly to find it.

Zhao Yi quickly got into work mode and went to the power engineering laboratory the next morning. However, he did not go to the operation room again. Instead, Yuan Haitao, Zhou Qing and others discussed the structure of the combustion chamber.

At the beginning, we discussed the fuel supply technology of divided pressure. The unique design does have great merits.

Zhao Yi kept asking questions about details.

Yuan Haitao couldn't give a complete answer. There was another engineer, Zhou Qing, who had a thorough understanding of this technology. He helped explain it for a long time and made Zhao Yi fully understand it.

Then Zhao Yi carefully studied the improvement plan.

Improvements in technical design may not sound difficult, but in fact, the difficulty is still very high.

At first, Zhao Yi wanted to directly study the "Contact Rate" and come up with the most complete solution. But after using it, he found that it required a lot of energy. Just a design of the combustion chamber required so much energy, which shows that Calculating design changes will definitely require a huge amount of work.

"A small design requires so much work. Every plan is really the hard work of the researchers!"

Zhao Yi came to the decision with emotion. He did not need to design the combustion chamber to be very, very perfect. He only needed to make some basic corrections to make it more stable and controllable than before, and to provide greater power. It was enough, and there was no perfect application, only better. He started with the details and slowly made changes.

For example, the thickness and material of the partition piece.

This aspect involves a lot of knowledge, content, and even technology. Zhao Yi learned about it in detail, and then said, "If we adopt an arc-shaped design, the middle partition piece will let the space on the left If it's larger than the right side, about ten percent, will it make the control more flexible?"

His statement stunned Zhou Qing.

Yuan Haitao still couldn't understand it, but Zhou Qing thought about it carefully, and then he started to write and calculate.

That is also a very complicated calculation.

Zhao Yi didn't interrupt or give any guidance, he just looked at Zhou Qing with a smile. After about ten minutes, Zhou Qing took a deep breath and nodded vigorously, "Although I didn't make accurate calculations, in general, I guess it will definitely make the partial pressure more stable, and the control will naturally be more flexible."

"Really?" Yuan Haitao didn't understand.

"certainly."

Zhou Qing said very confidently, "The arc-shaped design can collide with the material of the partition piece internally, and there will be a buffering process instead of hitting it directly. It would definitely be better if it is a semicircle, but considering that the semicircle occupies It’s almost impossible to fill the space, so we can only bend the partition piece.”

"The exact optimal amount of bending still needs to be calculated. I think this is very meaningful and valuable!"

Zhou Qing was even a little excited as he spoke.

Zhao Yi said calmly, "Since it makes sense, let's make a detailed calculation."

This time Zhao Yi participated in the calculation.

After Zhao Yi participated, Yuan Haitao and Zhou Qing realized what "super fast computing power" is. There were many things that they needed to calculate carefully. Zhao Yi seemed to think about it and got the results immediately. They went to verify the findings. The result is absolutely correct.

In terms of pure calculations, they are completely unable to keep up.

Zhao Yi explained to them while doing the calculations. The super fast speed made them unable to keep up with the ideas. Later, they simply gave up and waited for the results. It took about half an hour to reach the conclusion of the calculations.

Zhou Qing quickly recorded the results. He said excitedly, "I think this can be reported. In the future, the partitions of the combustion chamber will be designed as arcs..."

"No need yet."

Zhao Yi waved his hand and said, "I just discussed one partition film, and there are many more in it. I think each one can be demonstrated in a targeted manner to come up with the most complete plan."

"Yep!"

This time Yuan Haitao and Zhou Qing could only nod.
