Ten minutes later, Professor Liang was done with his calculations. He was overjoyed." What a genius design!"”
Then, the scientist grabbed Lin Ye's hand." Little Ye, quickly follow me to the laboratory.”
He walked out without any explanation.
"Old Liang, you're still so impatient.”Professor Yuan laughed and followed behind.
In the evening.
In the Chief Instructor's office, Chief Instructor Yang was sorting out the information of many people who had applied for merit. In front of him was a list of people who had contributed to the Eagle 2000 radar absorbing material.
The first name on the list was Lin Ye's.
"Hmm? Why isn't Professor Lin's information complete?" Chief Instructor Yang frowned.
The information only stated Professor Lin's name, age, professor at Shuimu University, and chief expert in radar absorbing materials.
"Bang!"
At this moment, the door was pushed open forcefully. An assistant ran in panting and said excitedly,"Chief teacher, we succeeded, we succeeded!”
The assistant spoke incoherently, and Chief Instructor Yang was baffled."What succeeded?"
"The single crystal alloy blades of the 15-revolution engine have succeeded!”
"What did you say?"
Chief Instructor Yang stood up in shock." Say that again?”
The assistant first took a deep breath and then said,"I just came from Elder Liang's place. The single-crystal alloy blade invented by Professor Lin Ye has been successfully tested.”
"Professor Lin?" Chief Instructor Yang was puzzled.
Wasn't Professor Lin Ye an expert in stealth materials? Why did he suddenly have a single crystal leaf?
However, there was no time to ask. Chief Instructor Yang immediately stood up and was about to go to the laboratory. When he walked to the door, he remembered that Professor Lin's information was incomplete. He said to his assistant,"Professor Lin's information is not detailed. You can ask the professor to complete the information later.”
After saying that, Chief Instructor Yang walked out.
If the single-crystal blade was really invented, then the heart problem of the domestic engine could be solved. The more Chief Instructor Yang thought about it, the more excited he became. He quickened his pace and jogged all the way.
Chief Instructor Yang ran to the door of the laboratory and heard the cheers inside.
Elder Liang's voice was the loudest.
When Chief Instructor Yang walked in, he saw Elder Liang shouting," That's great! We succeeded! That's great!"”
The old man danced around excitedly like an old child.
When the old man saw Chief Instructor Yang, he excitedly hugged Chief Instructor Yang and shook his shoulders."Comrade Yang, I have good news for you. We have succeeded. We have successfully broken through the manufacturing process of single crystal blades. It has been 30 years, a full 30 years…”
As he spoke, Elder Liang was so excited that he cried. Tears flowed down his face.
" Elder Liang, you..." The old man was usually cheerful and optimistic. This was the first time Chief Instructor Yang saw the old man cry, and he felt a little flustered.
"I'm fine, I'm happy. The Starstreak Empire has locked us up for thirty years, and I've been feeling aggrieved. Today, we can finally hold our heads up high. The Starstreak Empire can no longer lock us up.”Elder Liang smiled excitedly with tears on his face.
"Has Elder Liang's problem with the single crystal alloy been solved?”Chief Instructor Yang confirmed.
"Little Ye." Elder Liang turned around and shouted.
Lin Ye took out a single crystal blade that had just been produced in the laboratory and showed it to Chief Instructor Yang.
Chief Instructor Yang put on a pair of white gloves first, and his hands trembled slightly." God, I can't believe it. Did Professor Lin really make it?”
"Yes, this single crystal blade can work continuously for 550 hours at 2000 degrees Celsius and 20 tons of high pressure.”Lin Ye introduced.
"Good, good, good. That's great!" Chief Instructor Yang was so excited that his entire body could not help but tremble.
It was this small leaf that pressed down on him and the thousands of researchers of the Air Force like a mountain. It was like a nightmare that had troubled the Dragon Country's Air Force for 30 years.
In the past 30 years, the Dragon Country's rockets could reach the moon. The domestic civilian large passenger aircraft had also begun to develop, and the fourth-generation fighter aircraft had also been born. However, the engines on the fighter aircraft had never been able to be domestically produced.
There was a piece of information:
In this world, there were 12 countries and regions that could produce their own third-generation fighter jets.
There were nine countries that could produce their own nuclear weapons.
There were five countries that could produce intercontinental ballistic missiles on their own.
There were three countries that could produce high-thrust military rotating engines.
There were only two countries that could produce their own large ducted, high-thrust, and high-performance civil rotating engines, which were Starstreak and Eagle.
It could be seen very intuitively that on this cruel human pyramid, the motherland was still quite a distance away from the top.
" Large bypass, large thrust, high performance and high reliability rotating aero engine " is a heart disease that we can't avoid at present.
Some people might be curious as to why it was so difficult to sail.
Imagine, the maximum thrust of the Bear-31 rotating engine of the Bear-27 was 12.5 tons. Two Bear-31s could propel the Bear-27 to fly at more than twice the speed of sound. However, the fan of the Bear-31 was less than 900 millimeters in diameter, and the turbine was less than 300 millimeters in diameter.
According to the basic principles of physics, forces interacted with each other. In other words, such a size fan and turbine would have to withstand a force of 12.5 tons at all times.
To put it in perspective, the performance of a muscular man pushing a car with a steel gun at his throat on television was similar to the performance of a rotating engine. However, the muscular man pushed the car slowly, while the rotating engine had to push the plane to fly at twice the speed of sound. Each component had to withstand the extremely harsh test of high temperature and high pressure.
In addition, a rotating engine for a supersonic fighter jet was generally only about 1 meter in diameter and 4 meters in length. Taking the Bear-31 as an example, such a small cylindrical object had to be fitted with a fourth-stage fan, a nine-stage turbine, a two-stage turbine, a convergent-expansion spout, a combustion chamber, an afterburner, and a cooling air passage. A fuel control system had to be installed around it. Therefore, it was extremely difficult to design and manufacture a high-performance rotating engine.
In the world, only the Eagle Kingdom's Rolls-Royce, the Starstreak Kingdom's Pratt Whirlpool, and the General Electric Company had mastered the first-class level of rotating engine manufacturing technology. The two countries were considered second-rate, and this was a real monopoly industry.
Russia and China have yet to begin the industrial production of single crystal hollow turbine blades.
It wasn't hard to understand why the scientists here were so excited that they were crying.
"God bless the Dragon Kingdom's Air Force!" Chief Instructor Yang looked at Lin Ye excitedly and said from the bottom of his heart,"Professor Lin, on behalf of the Eagle 2000 project team, 120 research units, and 18650 people, I would like to express my gratitude to you for your outstanding contribution. I was just preparing to report your merits, but it seems that one is not enough.”
