Qiu Wenan asked slightly worriedly, "Boss, is there a problem with this design?" ”

Li Tianfeng nodded: "As far as electronic digital fuel regulation is concerned, your design is a little bulky, and it should be designed to be lighter, more advanced, more reliable, and the technical content must be higher." ∮ ∮ point∮ little ∮ said, x."

The fuel regulators that you have been in contact with and understand before are basically mechanical, and such fuel regulators are relatively bulky, such as the fuel regulator of turboprop B, which weighs dozens of kilograms and is not small.

Aero engines, whether they are turboshaft engines, turbofans, or turboprop engines, the weight of the engine must be strictly controlled, and the weight should be reduced as much as possible under the premise of ensuring the design performance and reliability.

Li Tianfeng knows that everyone's thinking is still limited to the mechanical fuel regulator, thinking that on the basis of the mechanical fuel regulator, add some electronic induction elements - excellent - excellent - small - say - more - new - the fastest - www.uuxs.cc - pieces, and add these things to become an electronic digital fuel regulator.

Seeing that everyone was stunned for a moment, and had not yet reacted, Li Tianfeng said: "Everyone should jump out of their own thinking circle, don't imprison yourself, we are designing an electronic digital fuel regulator, I think as a fuel regulator for the 'TFWZ001' turboshaft engine, it should be designed like this......"

Li Tianfeng spoke in detail and talked about his design ideas as a whole, and suddenly, everyone's eyes lit up, and there was even a feeling of being opened.

In terms of design, sometimes the key is to pierce that layer of window paper, and Li Tianfeng is very clever to pierce this layer of window paper, and everyone seems to have entered a new space all of a sudden.

The senior engineers in the conference room, all of whom are good at aero engine control system design, now listened to Li Tianfeng's words, and at the same time, their eyes lit up. I also felt slightly in my heart, fortunately I joined Tianfeng Technology Company wisely, and I was fortunate to be exposed to these new things, and my design level rose rapidly during this period of time.

Just like today, it seems that I have completely entered a new design world, and my design level has faintly improved. If you participate in the design of this new electronic digital fuel regulator in the whole process, the design level will rise.

Qiu Wen'an, Sun Xiaoping, and Wu Shungao also quietly glanced at each other, and the three of them all felt and gained in their hearts, and Qiu Wenan even sighed in his heart, Mr. Li is worthy of being the supreme god in everyone's hearts.

"Did you hear that?" Li Tianfeng asked loudly.

Everyone nodded. Sun Xiaoping even said: "Boss, when you talk about this, we should be able to design this new type of electronic digital fuel regulator." ”

Li Tianfeng was also very happy, "Everyone, everyone must understand that we are designing the top turboshaft engine in China. Everyone should think outside the box and don't imprison themselves. Otherwise, you can only stand still. ”

Remember!

Then, everyone discussed and exchanged the design of the lubricating oil pump and the design of the entire lubricating oil system, and Li Tianfeng put forward some suggestions for improvement.

The design of the turboshaft engine of the "TFWZ001" type, the design of the core engine has been completed. Successively carry out a series of parts processing, control system, accessory system design has also begun to roll out, Li Tianfeng's goal is to complete the comprehensive design this year, next year to start a series of tests. Even the assembly of the first demonstrator began.

………

No. 1 processing workshop.

"TFWZ001" turboshaft engine centrifugal impeller all machining has been completed, centrifugal impeller is a very key part of the whole engine, although no new materials are used, but a new design is adopted, its blade design is different from the general centrifugal impeller, is a new design.

The centrifugal impeller is also the fastest processing, has completed the machining, is being inspected, the marble inspection platform of the first workshop, two parts are placed there, very conspicuous, very beautiful.

On the dark marble platform, two parts with a metallic luster of titanium alloy are very attractive and visually impactful, and an inspector is wearing white gloves and is beginning to carry out various inspections in earnest.

The dimensions of each item were checked and recorded one by one, and it can be seen from the happy face of the inspector that the processing quality of this part should be in good condition.

Li Tianfeng knew that these two parts had entered the inspection, and he was walking over with great interest, seeing these two parts, Li Tianfeng was happy in his heart, from the appearance, these two parts were good, seeing that a lot of sizes had been checked and measured, Li Tianfeng asked.

"What about 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 dimensions, and all of these dimensions are qualified, and none of them are out of tolerance." ”

Li Tianfeng thought in his heart, Zhang Can is good, he must have put a lot of effort, otherwise, where can the processing be so perfect, especially the processing of the new type of blade such as centrifugal impeller, which must have not been encountered before, and it is not easy to process such a blade for the first time.

Li Tianfeng was very happy and interested, and personally watched the inspectors inspect the dimensions and technical conditions.

All the dimensions of the inspection are qualified, technical conditions, such as runout, cylindricity, parallelism, etc., can be checked out of the table, the same all qualified, can not be checked by the table, wait a minute will carry out the three-coordinate inspection.

Suddenly, the inspector frowned and asked, "Mr. Li, the blade of the centrifugal impeller is a new type of blade design, I have not inspected such a blade, and it cannot be checked by conventional testing methods." ”

Li Tianfeng said with a smile: "Conventional methods can't be checked, you can do three-coordinate measurement!" ”

Such a blade shape can only be measured by three coordinates, the inspector opened the measurement sheet, and then sent it to the three-coordinate instrument not far away for inspection, Li Tianfeng also followed, wanting to see the inspection of these blades.

The processing quality of the blade, whether it is qualified or not, is directly related to the quality of the whole centrifugal impeller, and even related to the overall performance of the centrifugal impeller, Li Tianfeng is very concerned.

It was a little beauty who looked relatively young, and when she saw such a leaf measurement, she couldn't help frowning, and she didn't know how to start.

So young, there should be no work experience for a few years, it should belong to a group of newly recruited employees of Tianfeng Technology, and it should not be a few months after entering Tianfeng Technology, and it is normal to not know how to start.

Soon, a 30-year-old inspection technician came over, Li Tianfeng came to the No. 1 workshop more, and knew the inspection technician as if his surname was Zhou.

Seeing Li Tianfeng, the inspection technician Zhou Gong was slightly nervous, but he still greeted warmly: "Mr. Li, you came here in person." ”

Li Tianfeng nodded: "Immediately measure the blade shape of this centrifugal impeller, I want to take a look at the processing quality of these blades." ”

The inspection technician immediately nodded his head, took matters into his own hands, and began to measure the three coordinates. The blades of the centrifugal impeller are guaranteed by a lot of coordinate sizes, and if you want to check these blades, you must measure the coordinate sizes one by one, which is very cumbersome to measure, but Li Tianfeng seems to be very patient and has been waiting on the sidelines.

Drip, drip, drip

With a slight dripping sound, the probe of the three-coordinate measuring instrument measures the part, and every time it touches the surface of the part, it will make such a sound, and the sensitive probe will flash slightly red.

Minute by minute.

Suddenly, the inspection technician stopped, frowned and thought about it, and continued to measure, it seemed to be wrong, and then stopped, and so on several times, Li Tianfeng knew that something must be wrong, and couldn't help but look at the computer screen of the three-coordinate measurement.

The coordinate measuring instrument is connected to the computer, and the computer is equipped with measurement software, and each size to be measured will also appear on the computer, at a glance, at a glance.

Li Tianfeng found that there was a coordinate size that was obviously wrong, and the design value was several points off, Li Tianfeng also frowned, and wondered for a while, shouldn't it, so many coordinate sizes in front of him are qualified, how can this size be unqualified.

You know, the blade of the centrifugal impeller is processed by CNC milling, generally speaking, there will be no such situation, once there is a failure, it is often a large number of coordinate size unqualified, not such a size is unqualified.

Zhou Gong, who operated the three-coordinate instrument, was also puzzled, according to his own experience, such a thing usually does not happen, and he was puzzled.

The inspector just now was also beside him, and when he saw this situation, he said worriedly: "Mr. Li, this centrifugal impeller will not have an out-of-tolerance blade coordinate size." ”

Li Tianfeng shook his head, "Let go of this coordinate size, and then measure the next coordinate size and give it a try." ”

Zhou Gong operated according to his words, but the result was not good, and this size was not qualified, and it was also several points short.

Li Tianfeng's face changed slightly, could it really be that the processing was out of tolerance and the parts were unqualified?

Zhou Gong, the inspection technician, obviously did not believe in evil, and measured a coordinate size point again, but it was still unqualified, and the deviation was about a few wires.

"Mr. Li, the continuous measurement of multiple coordinate dimensions is unqualified, it is estimated that there is a quality problem in processing, maybe there is a problem with the CNC program of the precision milling blade type in a certain program section." Zhou Gong analyzed.

Hearing this, the inspector next to him looked sorry, the blade type is unqualified, and a number of coordinate points are unqualified, this centrifugal impeller is wasted, it's a pity, the processing is so beautiful, there is actually a zài leaf type out of tolerance!

Today's four watches, the first one is sent.

A new month and a new beginning, everyone's monthly pass support! (To be continued......)
