One hundred and sixtieth chapters appear flaws
Qiu Wen'an asked with a little concern, "Boss, are there any problems with this design?"
Li Tianfeng nodded: "As electronic digital fuel regulation, you have designed it a little bulky. It should be designed with lighter, more advanced, more reliable, and more technical content. ∮"
The fuel regulators that you have come into contact with and understand before are basically mechanical. Such fuel regulators are relatively bulky. For example, the fuel regulator of turboprop b weighs dozens of kilograms and is not small in size.
For aircraft engines, whether they are turboshaft engines, turbofans, or turboprop engines, the weight of the engine must be strictly controlled. On the premise of ensuring design performance and reliability, weight reduction should be carried out as much as possible.
Li Tianfeng knew that everyone's thinking was still limited to mechanical fuel regulators, thinking that based on mechanical fuel regulators, some electronic induction components will be added, and these things will become electronic digital fuel regulators.
Seeing that everyone was stunned and not reacted, Li Tianfeng said: "Everyone should break out of their own thinking circle and not imprison themselves. We are designing electronic digital fuel regulators. I think as the fuel regulator of the 'tfwz001' type turboshaft engine, we should design this way..."
Li Tianfeng said it in detail and explained his design ideas in the overall way. Suddenly, everyone's eyes lit up, and even felt a sudden feeling.
Sometimes the key to design is to break through the layer of window paper, while Li Tianfeng cleverly breaks through this layer of window paper, and everyone seems to have entered a brand new space at once.
The senior engineers in the conference room are all good at designing aircraft engine control systems. Now, after listening to Li Tianfeng’s words, they were also slightly touched in their hearts. Fortunately, they wisely joined Tianfeng Technology Company and were fortunate to come into contact with these new things. Their design level has increased rapidly during this period.
Just like today, I feel like I have completely entered a brand new design world, and my design level has made a vague progress. If I participate in the design of this new electronic digital fuel regulator throughout the process, the design level will continue to rise.
Qiu Wen'an, Sun Xiaoping, Wu Shungao also looked at each other quietly. The three of them were all touched and gained. Qiu Wen'an even sighed in his heart that Mr. Li is worthy of being the supreme god in everyone's hearts. His design is of great quality and he can only look at it.
"Do you all understand?" Li Tianfeng asked loudly.
Everyone nodded. Sun Xiaoping even said: "Boss, after you said this, we suddenly realized that we should be able to design this new electronic digital fuel regulator."
Everyone has gained something, and Li Tianfeng is also very happy, "Everyone, everyone should understand that we are designing the top turboshaft engine in China. Everyone should think pioneeringly and not imprison themselves. Otherwise, they can only stand still."
Remember, everyone!
Then, everyone discussed and exchanged the design of the lubricant pump and the design of the entire lubricant system together, and Li Tianfeng put forward some improvement suggestions.
The design of the "tfwz001" type turboshaft engine has been completed. A series of parts processing, control systems, and accessories systems have also begun to be designed. Li Tianfeng's goal is to complete the comprehensive design this year, start a series of tests next year, and even start the assembly of the first verification machine.
………
No. 1 processing workshop.
The "tfwz001" type turboshaft engine centrifugal impeller has been completed. The centrifugal impeller is a very critical part of the entire engine. Although there is no new material, it adopts a new design. The leaf design is different from the general centrifugal impeller. It is a brand new design.
The centrifugal impeller is also the fastest process, and the mechanical processing has been completed and inspection is underway. On the marble inspection platform of workshop No. 1, two parts are placed there, which are very conspicuous and beautiful.
On the dark marble platform, two parts with titanium alloy metallic luster are very beautiful and visually impactful. An inspector is wearing white gloves and is beginning to conduct various inspections seriously.
The sizes were checked one by one and recorded one by one. From the inspector's face, it can be seen that the processing quality of this part should be good.
Li Tianfeng knew that these two parts had been inspected and was walking over excitedly. Seeing these two parts, Li Tianfeng felt happy. From the appearance, these two parts were good. Seeing that many dimensions had been checked and measured, Li Tianfeng asked.
“How is the quality of the parts?”
Seeing that it was Li Tianfeng, the inspector immediately said happily: "Mr. Li, the processing quality is very good. I have measured most of the sizes, and all of them are qualified and there is no exceeding the difference."
Li Tianfeng thought to himself that Zhang Can is good and must have put in a lot of effort. Otherwise, how could it be processed so perfectly? Especially the processing of new blades such as centrifugal impellers must have never been encountered before. It is not easy to pass such blades for the first time.
Li Tianfeng was very happy and was also excited. He watched the inspector conduct various sizes and technical conditions on the side.
All dimension inspections are qualified. Technical conditions such as jumping, cylinder, parallelism, etc. If you can check the meter, you will also pass the meter inspection. If you cannot pass the meter inspection, you will conduct a three-coordinate inspection later.
Suddenly, the inspector frowned and asked, "Mr. Li, the blades of the centrifugal impeller are a new type of blade design. I have never checked such blades, so I can't check them out with conventional testing methods."
Li Tianfeng smiled and said, "If you can't check the conventional method, you can do three-coordinate measurement!"
Such a leaf shape can only be measured by three coordinates. The inspector issued a measurement order and then sent it to a three coordinate meter not far away for inspection. Li Tianfeng also followed him, wanting to see the inspection of these blades.
The processing quality of the blades and whether they are qualified is directly related to the quality of the entire centrifugal impeller, and even the overall performance of the centrifugal impeller. Li Tianfeng is very concerned about it.
The measurement was a little beauty who looked younger last year. Seeing this leaf-shaped measurement, she couldn't help but frown and didn't know how to start.
He is so young and has few years of work experience. He should be a group of new employees recruited by Tianfeng Technology. He should have been in Tianfeng Technology for a few months, so it is normal not to know how to start.
There is a special inspection technician in the measurement of three coordinates. Soon, an inspection technician in his thirties came over. Li Tianfeng came to the No. 1 workshop more often, and he knew this inspection technician. It seemed that his surname was Zhou.
Seeing Li Tianfeng, the inspection technician Zhou Gong was a little nervous, but he still greeted him enthusiastically: "Mr. Li, you are here in person."
Li Tianfeng pointed out: "Immediately measure the leaf shape of the centrifugal impeller, and I want to see the processing quality of these blades."
The inspection technician immediately nodded and started to measure the three coordinates by himself. The blades of the centrifugal impeller are guaranteed by many coordinate sizes. To check these blades, the coordinate sizes must be measured one by one. There are many coordinate sizes, which is very cumbersome to measure, but Li Tianfeng seems to be very patient and has been waiting aside.
Drop, Drop, Drop...
With a slight sound of drops, the probe of the three-coordinate measuring instrument measures the parts. Every time it touches the surface of the part, it will make such a sound, and the sensitive probe will flash slightly red.
Time passes by minute by minute.
Suddenly, the inspection technician stopped, frowned and thought for a while, and continued to measure again, but it seemed that it was wrong, and then stopped again. After repeated this several times, Li Tianfeng knew that something must have been wrong, so he couldn't help but look at the computer screen of the three-coordinate measurement.
The three-coordinate measuring instrument is connected to the computer. The computer is equipped with measurement software. Each measured size will also appear on the computer. It is clear at a glance.
Li Tianfeng found that there was a coordinate size that was obviously wrong, which was several lines different from the design value. Li Tianfeng also frowned and felt puzzled. It shouldn't be. So many coordinate sizes in front were measured, so how could this size not be qualified?
You should know that the blades of centrifugal impellers are processed through CNC milling. Generally speaking, this situation will not occur. Once unqualified occurs, a large number of coordinate sizes are often unqualified, rather than such an unqualified size.
Zhou Gong, who operated the three-coordinate meter, was also confused. According to his own experience, such a thing generally would not happen, and he was puzzled.
The inspector just now was also there. Seeing this situation, he said worriedly: "Mr. Li, this centrifugal impeller will not have excessive blade coordinate size difference."
Li Tianfeng shook his head, "Let me let this coordinate size go, and then measure the next coordinate size and try it."
Zhou Gong operated as he said, but the result was not good. The size was not qualified and it was several wires shorter.
Li Tianfeng's face changed slightly. Could it be that the processing is really poor and the parts are not qualified?
Inspection technician Zhou Gong obviously didn't believe in evil, so he measured a coordinate size point again, but it was still unqualified, with a few traces of excess.
"Mr. Li, the measurement of multiple coordinate sizes in succession failed. It is estimated that there is quality problem with the processing. Perhaps it is because of the problem with the fine milling leaf-type CNC program in a certain program segment." Zhou Gong analyzed.
Hearing this, the inspector next to him looked regretful. The leaf shape was unqualified and multiple coordinate points were unqualified. This centrifugal impeller was considered useless. It’s a pity that the process was so beautiful that the leaf shape was extremely poor!
