More than 20 people were invited to participate in this test at the Xichuan base. Everyone gathered in a second-floor control room more than 30 meters away from the engine. They could see clearly from a high position that the controllers were constantly correcting the data and controlling the test.
Various instruments in the room made buzzing sounds.
"The air intake system is ready!"
"The exhaust system is ready!"
"The ignition system is ready!"
"The power control system is ready!"
!
The voices of the controllers came and went, and everyone's heartbeats began to accelerate.
"Chief, you can conduct ignition testing at any time!"
Qin Lie came to Chen Youde to report.
"Mr. Qin, the order is yours, you can give instructions at any time!"
Chen Youde gave this honor to the other party.
He nodded and issued orders to the scientific researchers around him.
"Ten seconds to ignition! Ten, nine,, seven!"
When the countdown ended, the scientific researchers pressed the start button, and saw a flash of light from a certain part of the "Taundouyun". Then the huge turbine began to rotate, and the rotation speed became faster and faster. However, within a few seconds, the engine had already started to rotate.
The tail end produces a powerful airflow, which can be seen with the naked eye.
"There are no problems with each system. Please indicate whether to enter the next testing phase!"
the controller asked loudly.
"On to the next level!"
Professor Qin Lie issued the command again, and a moment later the engine made a loud roar, the turbine speed increased suddenly, and the impact of the airflow caused the inspectors in the control room more than 30 meters away to feel shaking.
How big is the impact of the airflow at this time? If there was a truck at the rear, the truck would be in the sky now. If it were not controlled by hundreds of powerful nuts, the engine would have flown to an unknown place.
"Each system is working normally, and the current parameters are completely normal. Do you want to enter the next stage of testing?"
"continue!"
At this time, everyone's hearts were in their throats, and Liu Lang's palms were sweating.
"boom!"
Speeding up again, the turbine has turned into a hot wheel, emitting a whitish fire. The length of the flame is more than five meters, like the flames caused by the friction of a meteorite falling to the earth.
At this time, the temperature inside the turbine has exceeded a thousand degrees. It is completely like a steel-making furnace. This is a severe test for the materials. There is sweat on the foreheads of all the scientific researchers, but no one pays attention to the sweat. They all watch intently.
Analytical instruments in front of you.
This state lasted for a full ten minutes, giving everyone a strong shock. The brackets used to fix the engine on the ground trembled slightly. Liu Lang even felt that the entire factory seemed to be shaking, as if the next moment
It will be carried to the sky by the power of the engine.
"The data is completely up to standard, the data is completely up to standard, please give instructions!"
Just after ten minutes, one of the testers shouted.
"The power test is successful, stop immediately!"
Qin Lie shouted, his tone already trembling.
The test has now shown that there is no problem with the power of "Fengdouyun" and it has reached the ideal state. Now there is only one last test left, which is to see if there is any damage to the inner chamber of the engine.
Of course, there must be some damage. The engine has a lifespan. Generally, it is good if it can last for one or two hours under extreme conditions. Of course, it does not mean that the engine will be disabled after one or two hours of use.
This is the case in the extreme state. Generally speaking, an aircraft will fly once and this extreme state will not occur for too long. A few minutes is considered a long time. Therefore, generally speaking, an aircraft will have to fly dozens of times before the engine will be compared.
Major overhaul.
The engine has been running under extreme conditions for ten minutes just now. The materials of the engine will definitely be damaged. Next, the scientific researchers will test the materials. If the test results completely meet the expected goals, then the test is basically successful. At most, it will need to be carried out.
A destructive test is to make this engine run "desperately" to see if its limit can reach the expected target. If it finally meets the target, then the test will be successful, and at this time it can be announced that the country has developed
It has its own engine, an engine that is comparable to that of Western developed countries.
It is true that there is still a big gap between the "Fengdouyun" and the engines produced by Boeing. This is mainly due to the lifespan. The maximum lifespan of engines in Western developed countries may be five or six hours, or even longer. Super lifespan means better performance.
The stability and maintenance costs are also lower, so compared with foreign countries, the country still has a long way to go, but this is a problem of accumulation, and the insurmountable gap between the two parties is no longer insurmountable.
As the engine turbine stopped running, the huge fan blades slowly stopped. A group of people hurriedly walked out of the control room and quickly gathered in front of the engine. One researcher even fell due to excitement, but there was no such thing.
No one paid attention to him, and everyone's attention was focused on the engine.
Liu Lang was the first to run up to him, and then he clung to the fan blades and watched.
"Liu Lang, be careful not to burn yourself!"
Someone shouted from behind. The temperature on the surface of the fan blades was now very high. If you touch it, you may burn off a layer of skin.
Of course, Liu Lang would not reach out and touch it. He was looking at it. The slight changes in the metal surface of the fan blade could tell the degree of damage to the stress and toughness of the material. Of course, he would still have to touch it with his hands after the temperature dropped.
Others can't see or touch it, but Liu Lang can. Although the accuracy is not comparable to that of other equipment, he can basically analyze it.
Liu Lang spoke after a moment.
"There should be no problem. In my opinion, this experiment was successful!"
"So sure?"
Professor Qin Lie asked from the side. At the same time, he also carefully looked at the changes in the texture on the surface of the fan blades. The changes were slight and the problem might not be serious, but he could not make predictions like Liu Lang's.
"Mr. Qin, don't forget that I can figure out various parameters of alloy materials just by thinking. I have read the information you just gave me. The texture on the surface of this fan blade shows that the internal structure has not been fundamentally affected.
The damage should meet the design requirements, so I think everyone can celebrate, celebrate the successful development of our country's first aircraft engine, and report the good news to the country at the same time. We have lived up to our mission and completed the tasks assigned to us by the country!"
Liu Lang said categorically.
"Wow! Great!"
Some people clenched their fists to express their inner joy when they heard what Liu Lang said. Liu Lang's ability to analyze alloy materials was unparalleled. He was so sure that it must be okay.
"Haha, Liu Lang, I feel relieved when you say that. But we still have to do what we should do. We will analyze the alloy surface materials later. I believe the results will be available soon. Come on, everyone goes to the control room first.
Drink some tea, the temperature here is too high and you will become a drowned rat if you stay any longer."
Indeed, the temperature around the engine was as high as fifty degrees, and everyone was covered in sweat. However, everyone was focused on "Following the Clouds" and no one paid attention to themselves.
