As everyone knew, the engine was the " heart " of an aircraft. From Professor Yuan, he learned that although China had developed an advanced fifth-generation aircraft like the Eagle 2000, there was still a large technological gap between the engine technology and the developed western countries. The major bottleneck was the serious shortage of thrust of the engine.
To solve the thrust problem of the engine, the turbine blades of the engine needed to have a higher ability to withstand high temperature and high pressure. The best material for high-temperature turbine blades was single-crystal alloy blades, but the manufacturing technology of single-crystal alloy blades had always been tightly sealed by the West.
Lin Ye's experiment was to break through the western blockade.
"Turn it on!"
Lin Ye gave a command, and the engine controlled by the system started up.
"Hu hu hu ~~"
The engine spewed out blue flames, and the meter showed that the temperature of the blue flames was as high as 1800 degrees.
The turbine blades inside the engine spun at high speed and turned red in a few seconds.
In such an extreme environment of high temperature, high pressure, and high-speed rotation, the turbine blades would creep.
The so-called creep refers to the material's distortion under the effect of external force, which can make the blade stretch, twist, and bend in the radius, affecting the service life of the blade.
In more serious cases, fatigue will occur, which may lead to fatigue fracture and endanger safety.
If the blade broke, it meant a crash. The pilot's life could not be taken lightly.
This was also the biggest difficulty in manufacturing the single crystal alloy blades.
"The simulation time is accelerated by 100 times.”Lin Ye said.
As soon as he finished speaking, time in the laboratory suddenly accelerated by 100 times. In other words, if it was in the real world, it would usually take hundreds or thousands of hours to conduct an engine experiment. But here, Lin Ye could accelerate time by ten times, a hundred times, a thousand times, or even ten thousand times. This could save a lot of time for repeated experiments.
It was as if he could fast-forward at any time.
In the blink of an eye, under the acceleration of time, the engine had been on for 200 hours.
Suddenly, an ear-piercing alarm sounded."Detected blade number 65, 90, 91, 102, 113, 118…120 bent and deformed.”
In the next second.
The engine started to spark, and then a huge fire started to burn.
The experiment failed.
The leaf couldn't withstand 200 hours, so it was obviously not qualified.
The lifespan of the F-110 turbine blades of the Fei Tian-22 was 9600 hours, while the system gave a lifespan of 25000 hours for the fifth-generation blades.
What were the benefits of having a long life?
The first is to save a lot of maintenance costs. The blade life of the Bear-31F engine is 800 hours. The maintenance cost is very high. Our country spends tens of billions on aircraft engine maintenance every year.
If the lifespan of the leaves could be increased by several times, it could directly save billions of military expenses every year.
In addition, the short lifespan meant that frequent maintenance was needed. If the aircraft could not fly, it would delay the deployment and combat of the aircraft.
If the fifth-generation single-crystal blade test was successful, then the " heart " that hindered China's aerospace engines would be completely resolved.
"System, I need all the data.”
A blue screen appeared in front of Lin Ye. All the data from the experiment was listed one by one.
What followed next was a large amount of analysis work, which sometimes took months.
After a while, Lin Ye was fully focused on analyzing and calculating the data one by one. He did not know that time was passing until a voice came from the outside world."Professor Lin, let's go."
"Oh, I'm here."
Lin Ye exited the System Space and looked out the window. It was already dark. It was already two o'clock in the morning.
The plane was leaving at three o'clock.
Lin Ye quickly walked out of the room. Downstairs, Professor Yuan and more than ten researchers had arrived. Everyone got on a minibus and drove out of the military compound.
Forty minutes later, a special plane flew into the sky and disappeared into the night sky.
Lin Ye sat by the window. He did not sleep but turned on his laptop to calculate the data. He had not finished analyzing the experimental data in the System Space just now, so he had to seize every minute and every second.
"Yes, Little Ye, is this the data from the engine test?”Beside him, Professor Yuan had just woken up from his nap and looked at him curiously.
"Yes." As Lin Ye spoke, he pulled out a three-dimensional design of the "single crystal blade" and corrected a few subtle parameters.
"Monocrystal leaves. Little Ye, you've done some research on this?”Professor Yuan was curious.
Lin Ye nodded with a smile.
"This difficulty is no less than invisible paint!”Professor Yuan said.
"There will only be challenges when there is difficulty." Lin Ye looked back at the professor and asked,""Professor, have you done any research in this area?”
"It's not research. I know Professor Liang from the Aerospace Science and Technology University. He's an expert in this field. Coincidentally, he also participated in the research of the Eagle 2000 project and was responsible for the development of the domestic engine.”
"I see. Then can you help me meet the professor?”
"Sure, I can see Old Liang this time.”
Lin Ye nodded and continued to calculate the data. Professor Yuan couldn't resist the sleepiness and continued to sleep.
The plane was very quiet.
Everyone was seizing the time to sleep.
Three hours later, the sky was bright. The plane announced that they had arrived in the sky above Sky Mansion.
They flew for another half an hour.
Up ahead, a military airport appeared in front of the captain. The captain picked up the walkie-talkie and called,""Tower, this is 001, this is 001, requesting landing.”
"Control tower, you are allowed to land. Please land on runway 3.”
"001 received."
The plane slowly began to descend.
A few minutes later, the plane landed steadily on the runway. The hatch opened and Lin Ye walked out.
Wow!
He was immediately attracted by an Eagle 100 fighter jet on the runway.
