I built a fleet of aircraft carriers in the game

Heart disease in the rabbit family! ! !
“Hu Tuan, you woke up and scared us to death…”
Hu Jie woke up and was still confused, “What’s wrong with me?”
He still didn’t know how he was lying in the hospital.
“Hu Tuan, did you know that you suddenly fainted?”
“Ah, I fainted?”
“The doctor said that you just had an operation three days ago, your body hasn’t recovered yet, and you’re too tired to work continuously. Fortunately, there’s nothing serious, you’ll be fine with a little more rest.”
is that so?
Hu Jie rubbed his face to wake himself up and asked, “How long have I slept?”
The colleague looked at the time, it was nine o’clock in the morning, and replied, “You have slept for seven hours.”
“What about the experimental results?” Hu Jie was most concerned about the experimental results.
“It’s already out.”
“What about the data, tell me quickly.” Hu Jie eagerly wanted to know the experimental results.
His colleague Fu Er whispered in his ear: “The experimental data simulates that the engine was running at high speed for 560 hours, and the No. 120 blade was bent and deformed, causing the engine to catch fire.”
560 hours, which is 20 hours higher than the 540 hours of the last experiment.
However, Hu Jie frowned.
At 560 hours, the blade could not withstand it, and it was obviously unqualified, and the experiment failed again.
The F110 engine turbine blade single crystal alloy life of Lao Mi’s fifth-generation stealth fighter is 5,000 hours, and the gap between 560 and 5,000 is too large.
What are the benefits of long life?
The first is to save a lot of maintenance costs. The big AL31 engine equipped on our J-10 needs to be repaired once every 300 hours. Considering that the working conditions of the aero-engine are very harsh, military aero-engines are generally overhauled about 3 times, that is to say, the AL31F’s Flight hours, that is, life is about 900 hours.
This indicator is far behind the military aviation engines of Western countries. According to public information, the average training hours of the third-generation combat aircraft units of the Chinese Air Force exceed 200 hours per year, which means that one AL31F engine needs to be overhauled in less than 2 years, and less than 5 years. It needs to be scrapped every year. If you count engine wearing parts, materials, etc., the cost and expense are staggering.
The country spends billions every year on fighter engine maintenance.
If the life of the blade is increased several times, it can directly save billions of military expenses every year.
In addition, the short lifespan means thatFrequent maintenance is required, and this maintenance will not be able to fly, which will delay the deployment and combat of the aircraft.
However, our country’s engine research and development foundation is weak, and it started late. In three years, Hu Jie’s team was able to improve the engine from zero to 560 hours, which is not easy.
How should I put it, the aero-engine R&D technology is more difficult than mushroom eggs.
If an aero engine is the heart of an aircraft, then the turbine blades are the “aorta” of the heart. At present, almost all the turbine parts of the world’s advanced gas turbine engines use single-crystal hollow blades. As a key component of the hot end of an aero-engine, the single-crystal hollow blade has to withstand a high temperature of 700 degrees above its metal melting temperature and a centrifugal tensile stress of about 1,000 kilograms.
It is no exaggeration to say that the force that each blade bears is equivalent to the horsepower generated by an F1 racing car.
Public relations for scientific research is extremely difficult.
The goal of Hu Jie’s team is that the single crystal hollow blade can work for 1000 hours.
In this way, our domestically produced engine can at least replace the AL31F engine, which can save the country tens of billions of funds every year.
There is still a big gap between 560 hours and 1000 hours, and we need to continue to work hard.
“Hey, Hu Tuan, what are you doing?”
At this time, Hu Jie sat up and wanted to get out of bed.
“I’m going back to the laboratory to analyze and summarize the reasons for the failure of this experiment.” After saying that, Hu Jie wanted to get out of bed.
“Hu Tuan, the doctor said you need to rest more, don’t you still have us?” a colleague persuaded.
“I’m fine now. I feel fine now, you see?” Hu Jie moved his body to prove that he was fine.
“Hu Tuan…” The colleague still tried to persuade him. At this moment, there was a knock on the door, and then two soldiers entered.
One of them was a general.
When Hu Jie saw the general, he quickly stood up and gave a military salute, “General Liu!”
“Commander Hu, are you in good health?” General Liu asked with concern.
“General, I’m fine, nothing serious.”
“General Liu, Hu Tuan said he was going to be discharged from the hospital. Just tell him about him and let Hu Tuan rest for a few more days.” A researcher beside the hospital bed couldn’t help but say.
“Hu Tuan, the body is the capital of the revolution. Take care of your body first. This is my order to you.” General Liu said seriously.
Instead, General Liu smiled and said, “I’m here to see you, and to pick you up to the Northwest First Aircraft Factory.”
“Go to Xifei?” Hu Jie was puzzled.
General Liu nodded, “I’ll tell you the reason in the car.” As he spoke, General Liu said to the soldiers behind him, “Xiao Zhang, help Hu Tuan pack his luggage.”
“I’ll do it myself.” “Hu Tuan, I’ll do it. You’re in good health, so I’ll do it.” The two R&D personnel helped pack Hu Tuan’s personal belongings.
After a while, Hu Jie was discharged from the hospital with General Liu.
He got into a military vehicle.
After the military vehicle drove out of the hospital, Hu Jie asked curiously, “General Liu, is there something important to go to Xifei in such a hurry?”
“Yes, there is something important, otherwise I wouldn’t rush to pick you up, Hu Tuan.” General Liu nodded, “I’ll tell you the details when we get to the airport and board the plane. I can only tell you now , XAC has developed a new fighter jet.”
A new type of fighter?
What kind of fighter plane needs General Liu to pick him up in person?
Hu Jie was suspicious.
