At around 11 o'clock in the morning, the assembly line was still in full swing and very busy. Pen, fun, pavilion www. biquge。 info{{

Because in the high-precision assembly line workshop, it is necessary to wear anti-static clothing, and after Xu Linyuan wears anti-static clothing, the whole person is like a hill.

At this time, seeing that the assembly line has entered the stage of packaging, Zhu Jiran and the scientific researchers of the experimental base are more serious and meticulous, and every detail must be kept improving, very cautious.

And although Xu Linyuan already knew a lot about the design, he couldn't help much in the assembly process, so he just stood quietly and watched.

This engine is very different from the traditional aero engine in terms of shape and structure, because it adopts a unique hollow loop channel and chain punch ring straight design, so its overall appearance is like a flat triangle, which is composed of high-strength composite materials, which can be well integrated with the wing.

The core engine in the middle is slightly similar to the traditional turbojet engine, but its shape structure is not round, but flat oval, which can better adapt to the pressure and resistance brought by the air, and the voice control is lower, which is a bit similar to the device structure attached to the propulsion system on the space battleship in the science fiction film, which gives this engine a bit of science fiction elements. {{}}

But in fact, not to mention its appearance, it is the structure and performance design of its core aircraft, because it is used in the field of civil aviation, the design adopted by this named WFE100 is a reference to the design idea of the chain link engine, in which the internal structure is also very different from the principle structure of the traditional aero engine.

At present, this aero engine is an engine designed by the experimental base for regional aircraft series, his single thrust stage is about 21000-26000dan, but its cruising fuel consumption will be about 38.5% lower than the traditional turbofan engine of the same level of thrust, which is 0.3kg/dan.h and has a lower voice, small size, lighter weight, and can fully realize silent navigation, and his CO, UHC, NOx value is also more superior than the engine of the same level.

Therefore, on the basis of this data, the performance of this WFE100 has been completely at the peak of the engine used in regional airliners, and it will be more advanced and more energy-saving in the application of small and medium-sized passenger aircraft.

Because this first WFE100 is to be delivered to COMAC for assembly and testing of their newly developed CRJ23 regional airliner, and to carry out a series of test tasks such as the first flight test, the experimental base designed this WFE100 series to meet the design requirements of COMAC to match the company's customized planning tasks. {{}}

Next, after the WFE100 is delivered to COMAC, Xu Linyuan will also assemble and produce the first WFE2200 series designed for large civil airliners, so as to compete with Pratt & Whitney's GP7200 or Rolls-Royce Trent 900 and other series engines used in Boeing 787 and Airbus A380.

Laugh at!

At this moment, Xu Linyuan was attracted by a soft sound.

When he looked up, he saw that the WFE100 on the assembly line had been assembled, and the sound he heard was the sound of the auxiliary machine operating when the engine was taken off the shelf.

At this time, I saw Zhu Jiran happily leading someone to place the assembled engine on the test bench, so he was busy and began to access various test instruments, preparing to run the engine and its built-in **EVS program system for initialization and debugging.

Xu Linyuan and Tan Zhizhong saw that they had entered the last link, and they immediately perked up, so they also followed to a display screen in front of the test bench.

Seeing that Zhu Jiran and a few people connected all the debugging and testing auxiliary equipment to the engine and started the relevant equipment and instruments, a series of parameter curves related to this engine suddenly appeared on the display screen in front of Xu Linyuan. {{}}

Buzzing!

At this time, after Zhu Jiran turned on a piece of equipment, when the instrument was running, the engine was successfully connected and began to run.

Xu Linyuan stood in front of him, and he could hear that the voice of this engine was very small, which was very small when heard indoors, and if he went outside, his voice was almost negligible.

After the engine was running, Xu Linyuan saw that the parameter curves on the display screen also began to change slightly.

Tan Zhizhong has been engaged in aircraft design and manufacturing for many years, and he is naturally very familiar with these, but at this time, when he looked at the changes in some parameters, his eyes were very hot, and he couldn't help muttering: "The ratio of the performance parameters of this engine, although I know it in my heart in the sample test stage, but after the first assembly is completed, his performance has been slightly improved, which is beyond my expectations......

"Are you saying that there is a change between the theoretical value and the actual value, is that good or bad?" Xu Linyuan couldn't understand the parameter change display on it, so he asked Tan Zhizhong. {{}}

Tan Zhizhong nodded and said: "Yes, simply put, the theoretical value is a value inferred in the design process, generally after the test, this data is not very different from the officially produced products, but there is also a small increase or decrease, which is within the allowable range, but the first engine we assembled is higher than the theoretical value, which is a very gratifying thing, indicating that the performance parameters and conditions of this engine in all aspects have been very mature, It's ready for mass production......"

After Zhu Jiran saw the test data at this time, his eyebrows fluttered, so he said to the assistant next to him: "Increase the power, conduct a simulated high-altitude operation test, and call up the **EVS system for initial debugging, and ......set it according to this actual value."

After hearing this, the assistant immediately complied.

Buzzing!

At this time, after the power of this engine was increased, everyone could hear that the sound it made was also much larger, and it sounded harsh, and Xu Linyuan saw on the actual display screen that its voice value did not reach the maximum value, and it was still about 20db lower than the maximum value. {{}}

Zhu Jiran turned on the SEMVS control system in the assistant, and after accessing through the terminal device, he saw that a human-computer interaction interface was immediately displayed on the display screen in front of him, and Zhu Jiran compared the values on the instrument screen in front of Xu Linyuan, and then set the relevant parameters on the interactive interface.

Of course, this initial setting is only carried out at the factory, which is equivalent to the factory setting, and when the engine is delivered to the user, they will actually set some controllable and changeable options to be officially put into use.

Whining!

When the engine ran for a while, Zhu Jiran completed the initialization setting compared with the test parameters, and then restarted it.

After restarting and testing all the links again, after the engine was running completely normally, Zhu Jiran asked the relevant instruments and equipment to be turned off and finally packaged, and finally printed with the eye-catching logo of the future group.

Then Zhu Jiran turned his head and said to Xu Linyuan: "After testing, there is no problem at all, and it can be delivered to the user's device for flight test use......"

After Xu Linyuan heard Zhu Jiran's affirmative reply, he was also in good spirits, and said to Tan Zhizhong: "The people of COMAC Group are probably waiting outside a little anxious now, Jack, you go and inform them so that they can prepare for the handover......"

"Okay!" Tan Zhizhong smiled and walked out.

Xu Linyuan, on the other hand, remained on the assembly line until he watched the workers slowly lower the final packaging process on the loading truck.

"Old Zhu, the work task of WFE100 has come to an end for the time being, and your task is still arduous in the future......" Xu Linyuan looked at Zhu Jiran and said.

Zhu Jiran saw that his newborn child was about to be sent to the user who had been waiting outside for a long time, and his eyes were a little reluctant, but after hearing Xu Linyuan's words, his eyes lit up again, and he shouted: "Yes, this FE100 is just a small fight, our highlight is the civilian WFE2200 and the military SUF110......"

Xu Linyuan saw that he had fighting spirit again, so he smiled and said: "There is still a month to go, and it depends on you whether our first WFE2200 can complete assembly and production......

"Don't worry!" Zhu Jiran patted his chest and said: "These designs have been modified and optimized countless times, and it took more than a year to test them alone, I believe that after our WFE2200 comes out, its strong performance will definitely surprise the gringos......"

Xu Linyuan smiled, then ran to the loading truck lightly, drove the loading truck, and slowly drove outside with the WFE100.

Click!

When the door of the workshop opened, Xu Linyuan drove the loading truck to a hall outside, and suddenly heard a burst of firecrackers outside the workshop.

Through this hall, the engine was fixed and packaged by workers to prevent collision and violent shaking, and after the last process was completed, the outer door was opened, and Xu Linyuan drove the loading truck out of the door.

When I came outside, I saw that there was already a large container delivery truck waiting there, and next to this big car, there were many cars and off-road vehicles parked.

In the sound of firecrackers, I saw that the commander-in-chief of the production department of COMAC Group in charge of the assembly greeted him with a happy smile, and after Xu Linyuan parked the loading truck in front of the car, the commander-in-chief said: "Finally, when Xu Dong's first WFE100 was successfully assembled and shipped out of the factory, this matter is off to a good start, and it is gratifying......

Xu Linyuan smiled and nodded, and then personally controlled the loading truck to load the engine into the big car sent by the Chinese businessman to pick up the first engine, and immediately someone carried out some protection and fixing work very carefully, and then closed the door.

After bidding farewell to Xu Linyuan, the big car slowly drove out of the north gate under the escort of several small cars, and went straight to the location of the aircraft assembly line of the China Commercial Aircraft Group.

The general manager of the parts department of COMAC who stayed behind then followed him to the factory office to go through the handover procedures, and Xu Linyuan suddenly felt relaxed.

Next, it depends on what kind of performance this WFE100 will play after testing on their CRJ23 by COMAC.
