"Fake driving!"

The on-site test commander gave a loud order and played a special command gesture for the test.

Although the monitoring control room adopts sound insulation measures, but the interval test engine is very close, but the noise of the monitoring control room will exceed 85 decibels during the test, and the test command has a special command gesture, and sometimes the test driver may not listen to clear orders.

Hearing the command's order, the test driver immediately started to fake driving, and the engine on the test bench immediately entered the state of false driving.

At this time, the engine on the test bench is still driven by the starter, and the fuel supply system starts to supply fuel to the combustion chamber without ignition.

"The oil supply in the combustion chamber is normal, the air pressure of the pneumatic nozzle is normal, the oil pressure is normal! The voltage is normal, and the atomization nozzle is normal!"

"The oil supply in the combustion chamber is normal, the air pressure of the pneumatic nozzle is normal, the oil pressure is normal!

The loud voices of several test drivers sounded in the monitoring room.

Everyone's faces were beaming with joy.

Liu Jianqing was also very focused at this time, looking through the wide thick glass at the engine that had entered the state of fake driving.

"Ignition! ”

The test driver pressed the ignition button, and the engine point emitted a sharp and steady sound, and the sound gradually increased!

Everyone in the monitoring room also felt the loud sound of the engine, and if they didn't speak loudly at this time, they really couldn't hear it clearly.

The so-called slow train working state is the minimum power state of the engine to work reliably and steadily, in general, the speed is 25% to 30% of the maximum speed, and the power is 3% to 5% of the maximum power.

The test run of the new aero engine generally adheres to the principle of gradual progress, such as the start just now, the fake start, and the current slow train working state.

After a few minutes of entering the working state of the slow train, the engine starts to enter the cruising working state, and after a period of stability, it enters the rated power state.

"Normal!"

"Normal!!"

"Normal !!"

Yang Jie heard the reports of these test drivers, but he felt how pleasant and pleasant these sounds sounded.

Konstantin, as the chief designer of this engine, was the most excited and excited, and at this time he was firmly clenched his fists.

Liu Jianqing and these generals of the military were all happy, and they all felt that this visit was really worthwhile.

Aero engine verification test is a total verification of its design, manufacturing process, materials and other aspects, only the engine verification test is normal, it means that the engine design, manufacturing process, materials and other aspects are no problem, it is feasible.

Liu Jianqing remembered that the turbofan 10 engine had a third-stage compressor disc rupture during the test run in previous years, and he also looked forward to seeing that this engine could successfully complete the test experiment.

Now that this engine has been verified and tested by so many scientific targets, it has been normal, and Liu Jianqing and these generals are very excited.

Wang Yonglin was also more excited in his heart, he looked at the engine on the test bench outside, and he knew that the real test was about to begin.

In a series of test runs just now, the maximum working state of the engine is the rated working state, which is far from reaching the maximum power working state.

When entering the maximum power working state, each part will be tested to the limit, whether it is a force test or a working environment test, it will reach the limit.

Under the maximum power working state, the turbine rotor, one of the hot parts, will output the maximum power, and its force will also reach the maximum state, and the temperature before the turbine will also reach the maximum, reaching thousands of degrees Celsius.

Under such high temperature and high stress conditions, it is a strict test for turbine blades, turbine disks and other parts.

As the temperature rises, the strength of the metal will fall, and when it reaches thousands of degrees Celsius, some metals will be red, soft, and not as strong as they would be at room temperature.

The pre-turbine temperature of the Hengshan turbofan engine is more than 1,000 degrees Celsius, and in such a high-temperature environment, the turbine blades, turbine discs and other parts will also encounter huge forces, outputting a grand thrust of 3,000 kilograms or more, and the degree of test can be imagined.

The commander-in-chief of the test couldn't help but glance at Yang Jie and Wang Yonglin.

"Yang Shao......"

Wang Yonglin looked at Yang Jie.

"Let's start with the maximum power test!"

Yang Jie nodded.

Seeing this, the test commander waved his hand, made a gesture, and shouted loudly: "Test run in the maximum working state!"

Hearing the command, the test driver started the engine again and gradually pushed the pusher forward, all the way to the extreme, to the maximum.

The sound of a sharp and steady engine test once again sounded in everyone's ears.

In the monitoring room, a series of instruments monitor the status of the engine, and on several LCD screens, all kinds of parameters are clear, and the data on the working status of the engine has been climbing and changing rapidly.

In all the monitoring and control rooms, there is only the sound of the engine working, no one speaks, and everyone's eyes are all staring at these instruments and meters, these LCD screens, watching these data keep beating.

From the beginning of the engine, the power has been climbing, from the 0.3 rated power state to the 0.5 rated power state, to the cruising working state, to the 1.0 rated power state, and then to the maximum power state.

Watching the power data climb, many people's whole hearts are lifted.

The engine has entered the maximum power state, and the various parameters of the engine displayed on the screen of the monitoring room are normal!

With the test commander ordered to stop, the verification test of the engine went very smoothly and became all the test projects, which can be called perfect.

As a witness of this test run, Liu Jianqing was happy and took the initiative to shake hands with Yang Jie: "Good, very good! You have done a very good job!"

Yang Jie is also extremely happy in his heart, the engine successfully completed the first test experiment, which means that there is no major problem in the design of the core engine of this engine, and his Hengshan turbofan engine design is just around the corner!

Wang Yonglin officially released loudly: "This test run is a happy success!"

All the monitoring and control rooms suddenly became a sea of joy, everyone cheered, and the test riders were even more excited and almost jumped.

Liu Fuping exchanged joyful glances with Konstantin, who also plucked his own eyes and wiped his slightly moist eyes with a tissue.

It was a success, and the engine designed by himself was successful! Although this engine was not successfully tested in his own country, he brought it to life here!

Yang Jie saw that everyone was so excited and excited, and his heart was also inexplicably excited, and the first test run of the first verification machine was successful, indicating that the progress of his company's engine had taken a solid step.

"Elder Liu, generals, for our support, let's have a few more drinks tonight to celebrate. ”

Liu Jianqing, who was in a good mood, said straightforwardly: "Okay, no problem!"

At this time, in front of the main factory of Yonghan Aviation Power Technology Co., Ltd., dozens of barrels of fireworks were lined up, and several security team members were lighting the fire, and a deafening sound of fireworks pushed the atmosphere to the top.

Hearing this salute, the employees of Yonghan Aviation Power Technology Company knew that the first test run was successful, and many people ran out of the factory and office, all of them happily looked at this gratifying salute.

"A little up, a little more. A little further to the right. ”

Several security guards are hanging a long grand banner above the factory gate, and on the red grand banner, there is a row of large white characters on it - warmly celebrate the success of the first test run!

In the afternoon, Li Kaiyuan also rushed over after getting the news, and he said to Yang Jie excitedly: "You kid did a very good job!"

The first test run of the aero engine produced by Yonghan Aviation Power Technology Co., Ltd. was a successful success, and within a few years, the Central Plains Province will be able to form a high-quality aviation industry, which is a good news worthy of special mention!

In the evening, Yonghan Aviation Power Technology Co., Ltd. held a grand celebration banquet, and many heads of the provinces and cities rushed over to celebrate Yang Jie and Yonghan Aviation Power Technology Co., Ltd.

In Vietnam and Japan, major news media and Quantum networks have carried out a large number of reports on the front page headlines.

China's first fourth-generation turbofan engine completed the first verification test run in Yonghan Aviation Power Technology Co., Ltd.!
