Tianfeng Technology Company.

Li Tianfeng was answering a phone call, and Yang Xianfeng called to congratulate him, "Mr. Li, the first engine has been completed smoothly, congratulations!" ”

Li Tianfeng said happily: "Mr. Yang, thank you, thank you, the engine has not been tested yet, and I don't know what the situation is." ”

Yang Xianfeng said: "Mr. Li, you are too modest, who in the industry does not know, Tianfeng Technology Co., Ltd., is absolutely a high-quality product, this engine test is definitely no problem." ”

Li Tianfeng Yile, did not think about it, his company still has such a good reputation in the domestic aviation industry, Li Tianfeng said: "Mr. Yang, when the test is completed, I invite you to drink, let's get together." ”

"Okay, that's it."

After talking to Yang Xianfeng on the phone, Li Tianfeng received several more calls, all of which came to congratulate him, and everyone knew that the first engine was completed smoothly. This is something to be congratulated on.

Commissioning Engineering Center.

In the first workshop, the employees were as if they were celebrating the New Year, beaming with joy and joy, and they were cleaning the plant again under the command of their workshop director.

The test workshop is naturally built to a high standard. The windows are bright and clean, spacious and bright, so cleaned down, the whole test plant is simply spotless, making people look very comfortable.

The test bench is the same, the test workshop where the test bench is located, with an area of more than 1,000 square meters, is a rectangular test workshop, and the front is a huge air intake grid. When the engine is tested on the test bench, the air flow comes in through these grids.

At the back of the test shop, in the direction of the rear end of the engine test, is also a huge exhaust grid from which the engine's tail jet flow will exit.

Several workers are cleaning in front of the huge air intake grid, cleaning the area in front of the air intake grid, and the ground in front of the air intake grid is also spotless.

The "TFWS001" turbofan engine was assembled in the final assembly workshop. The pre-commissioning review has been completed, and the conclusion of the review is that the commissioning is possible.

this engine. Transported from the assembly workshop, the transport vehicle loaded with this engine slowly drove into the test engineering center and entered the second test workshop.

The engine was lifted from the transport truck, along with the transport tooling, and several workers pushed the engine into the test workshop, and the engine was hoisted onto the test bench. Ready to start the first validation test.

After full preparation, the second day after this engine entered the second test workshop, at nine o'clock in the morning, the entire second test workshop people heard a crisp and loud alarm bell.

"Jingle Bell ......"

The test alarm bell sounds, and unrelated personnel leave the test area. In particular, the personnel in the test hall began to evacuate, and there could be no one in the yellow line in front of the air intake grid.

"Lao Li, I'm about to test for the first time, I'm really excited!"

"Yes, it would be nice if I could enter the test control room and see the test run in person."

"yes, I'd love to see the test for myself!"

The second test workshop, no, the employees of the entire test engineering center, when they heard the first test alarm ringing, their hearts were slightly excited, and many people stretched out their heads and looked in the direction where the test bench was located.

The huge test control room, with an area of two or three hundred square meters, is located on the second floor, condescendingly, through the thick glass, you can clearly see the situation of the test bench, and you can also clearly see the situation of the test bench.

The test control room is naturally close to the test workshop, and there is only one wall between the two, and the test control room is very well designed, and the view is very good on the second floor.

The observation window is even more huge, and on the partition wall between the two, the huge observation window with a height of two meters and a length of ten meters is standing in the test control room, and the situation of the test bench can be seen at a glance.

The test is about to begin, Li Tianfeng, Sun Xiaoping, Zeng Qinghai and other main designers, the main process personnel are all present, in addition, there are several test technicians of the second test workshop, as well as the technical director of the second test workshop.

Several test drivers were already in place, sitting at their posts with straight faces, looking at the LCD screen in front of them, as well as a large number of indicators and control buttons.

"Jingle Bell ......"

The test alarm bell rang for the second time, and then, a whistle was faintly heard from outside, outside the second test workshop, several employees with red armbands, were whistling, telling everyone to stay away from the test area.

In the test control room, several test technicians couldn't help but glance at each other, and their eyes could not hide the excitement and slight nervousness before the test run, this is the first verification test of the "TFWS001" turbofan engine!

Five minutes later, the test alarm bell rang for the third time!

"Jingle Bell ......"

The crisp and loud test alarm bell spread throughout the test engineering center, and when the bell stopped, Sun Xiaoping and Zeng Qinghai glanced at each other, and their eyes could not hide their joy. Of course, there was a trace of excitement in the eyes of the two.

After so much effort, from the beginning of the design to the processing of parts, and so much design verification, process verification, and hard sowing, now that it is the harvest season, the two of them are naturally a little excited.

Li Tianfeng's face couldn't help but wave, in fact, there was also a trace of excitement and expectation in his heart, Li Tianfeng waved his hand and said: "Start the test drive!" ”

Xiao Guoqiang, the technical director of the second workshop of the commission, personally acted as the commander of the commission, and Xiao Guoqiang, a senior engineer in his thirties, was previously a commissioning process supervisor of the process technology department, and was promoted to the technical director of the second workshop of the commissioning workshop in the latest round of middle-level management promotion.

Xiao Guoqiang said loudly: "Start the test drive!" The engine is in starting state! ”

The test driver, who had been prepared for a long time, gently pressed the green test start button, and everyone looked at the test bench through the huge glass observation window, and the engine began to start as the test button was pressed.

Engine start! The engine rotor accelerated from a stationary state to a specified slow state, and as the engine started, the sound of the engine working came, Li Tianfeng was experienced, and he pricked up his ears and listened carefully to the sound that came, instead of looking at the number of items on the LCD screen.

The sound is very steady, and there is no deafening feeling, Li Tianfeng nodded, such a sound intensity, speaking a little louder in the test control room, everyone can hear it basically clearly.

Today's engines are not ignited or fueled, but are driven by the starter to rotate the engine rotors, which is a cold operation.

The first is the cold operation of the slow state, which lasts for 150 seconds, that is, after two and a half minutes, several test drivers have reported loudly.

"Cold operation is normal!"

"Normal!"

"The number of items is normal!"

Xiao Guoqiang, the test commander, said loudly: "Enter the state of fake driving!" ”

With an order, one of the test drivers pressed the fuel supply button to supply fuel to the engine, but did not ignite, this state is called fake driving, and it is also a necessary test state for the test run.

"It's normal to fake driving!"

"The number of items is normal!"

Xiao Guoqiang said loudly: "Ignition, enter the slow state!" ”

The test driver pushed the accelerator to the slow state, and then pressed the ignition button, the engine ignition worked, the sound increased, and through the glass, the blue flame spewed out of the tail spray position could be faintly seen.

"The noise is normal!"

"The vibration is normal!"

"Fuel consumption is normal!"

"Thrust is normal!"

"All the numbers are normal!"

Several test drivers, loudly reported one by one, the engine entered a slow state, the noise is not very large, in the test control room, there is no deafening feeling, speaking loudly, or can hear more clearly.

The slow train is in normal condition! This means that the engine works successfully, Sun Xiaoping and Zeng Qinghai look at each other, one of them is in charge of design, one is in charge of technology, the engine is normal, and there is obviously a trace of joy in the eyes of the two.

Slow train working state, cruise working state, rated working state, cold start, hot start, etc., one by one test state test run one by one.

"Normal!"

"Normal!"

"Normal!"

“……”

Several test drivers reported loudly one by one, and everyone was happy in the test control room, and the test technicians in the second test workshop looked at each other, waved their fists vigorously, and expressed all the joy and excitement in their hearts.

Sun Xiaoping and Zeng Qinghai glanced at each other again, and the two of them were also happy, and Zeng Qinghai said: "Mr. Sun, you have succeeded for more than half of it!" ”

Sun Xiaoping nodded happily and looked at Li Tianfeng, at this moment, Li Tianfeng was looking at the engine on the test bench through the glass.

"Afterburner state test!"

Xiao Guoqiang, the commander of the test, shouted loudly, the afterburner state, this is the real test of the engine, Li Tianfeng's eyes have not left the test engine, and his ears have been listening to the sound of the engine test.

The tester pushes the throttle to the afterburner state, the engine gradually reaches the maximum working state, and the parts also reach the maximum load state!
