Chapter 133 Highlights
You should know that an aircraft engine is a highly complex and precise thermal machine, the heart of an aircraft, and the value of the engine accounts for 20%-30% of the value of the entire aircraft. In an aircraft engine, blades are a special part that has a large number, complex shapes, high requirements, and great processing difficulty, and has always been the key to engine production.
Thrust-to-weight ratio is an important technical indicator to measure engine performance. Given that the current achievable gas temperature before the turbine is higher than the load-bearing temperature of the turbine blades, the use of high-performance blade materials can increase the turbine inlet temperature, allowing the aircraft engine to obtain greater thrust without changing its weight, thereby improving the thrust-to-weight ratio.
Relevant research shows that for every 100°C increase in turbine inlet temperature, the thrust-to-weight ratio of an aircraft engine can be increased by about 10%.
"It is said that the average temperature of the turbine inlet of the current engine with a thrust-to-weight ratio of barely 10 is as high as 1600℃. It is expected that the turbine inlet temperature of the new generation of engines will reach about 1800℃ in the future." Cheng Huanan's voice was a little erratic with excitement.
"Our new T5 material can withstand high temperatures of 2400°C, directly surpassing the 2,000°C threshold!"
Academician Xie's emotions were equally surging. Having worked with materials for a lifetime, they knew very well what this data represented.
In other words, their current fighter jet engines use this new material, coupled with the T4 new titanium-aluminum alloy fuselage material that is much lighter than before. The combined effect is really one plus one equals N, allowing their fighter jet thrust-to-weight ratio to leap forward, surpassing the world's general level and making great strides towards doubling.
What kind of concept is this? This is an unimaginable concept!
"Wu Tong, the organization should give you a great credit!" A fuselage material with the most wide applications, a blade material with the highest performance requirements, two-pronged preparation, optimizing the direction of engine improvement, and assisting in perfecting the aircraft design... Wu Tong has brought a miracle of leapfrog progress to China Airlines.
"It's thanks to Academician Xie's good guidance, and the teacher who was busy and made perfect preparations. I just did some design and time follow-up work!" Wu Tong shook her head. Apart from deducing and designing material models and arranging experiments with the teacher, she really didn't do much else and couldn't take credit for it.
However, she was still happy that the physical material reached the value she expected.
"Fortunately, everything went smoothly in the experiment. Teacher, Academician Xie, you have been busy all day, you should take a break. We will repeat the preparation and verification process tomorrow, and then we will have to put these blades in a truly extreme environment for further verification!" The materials that will serve the Chinese Eagle cannot be sloppy in the slightest and must be refined. Thousands of tests are not surprising, and each item must be extremely precise to be responsible to the people and the pilots.
"I will further sort out and deduce the preparation process flow, and finally live up to your trust!"
Wu Tong finally had time to check the time. It was already late at night. They had eaten lunch and dinner in the laboratory. Everyone's attention was focused on the experiment.
"Haha... This should be an unexpected surprise. All of you are great heroes. Come on, I have prepared a midnight snack for you. Eat your fill first and I will arrange for someone to take you back to rest!" After the materials came out and Zheng Hongming, who was in charge of confidentiality supervision, received the notice, he rushed over urgently and greeted them with a smile.
He rushed over in a hurry and just caught up with the final test of the materials. The superior performance data was so great that even someone like him who had only a little knowledge of materials could feel it, and he was also excited.
"That's great! Xiao Zheng, you are the most attentive! Oh, there are also egg tarts and grilled wings. Wu Tong, these are what you young people like, you should eat more! The biggest credit for the success of this project belongs to you. Without your deduction and design, our assistance will be useless!" Old Cheng waved his hand and smiled at Academician Xie.
Young people generally need to be a little modest, but Wu Tong really doesn't need to be modest. If they could have achieved such great results at Wu Tong's age, the earth would not be able to accommodate them!
"Your teacher is right, being too modest is a sign of pride, Wu Tong!" Academician Xie joked.
"Yes, yes, my God, you have to leave some way for us. Let us be humble!" Young experimenters such as Ruan Chengxu and Xiao Lu responded with a smile, and suddenly the whole lounge was filled with laughter.
The experiment was an unprecedented success, and it would not be difficult to repeat the preparation. Everyone was in a relaxed and happy mood. Even if they had stayed up late into the night again, they were still as energetic as if they had been injected with chicken blood and did not feel tired at all.
After chatting and laughing, everyone finished the midnight snack prepared by Zheng Hongming. Wu Tong sorted out the final data statistics and encrypted them for storage.
After the others finished taking care of the lab, they all went back to rest. Under the coordination of Cheng Lao, the auxiliary experimenters who had signed the confidentiality agreement had quietly moved to the adjacent dormitory.
Zheng Hongming also arranged for someone to escort Wu Tong back to the dormitory. In just a few days, Wu Tong's importance to him was increasing day by day.
Wu Tong has already informed Peking University that they are adjusting his dormitory, and he is expected to move to the teacher's apartment on campus in the next two days. The single dormitories in Shaoyuan are mostly populated by overseas students, so they are relatively messy and not very safe from a confidentiality perspective.
The day after the T4 new alloy material came out, which was the day the project was approved, Wu Tong's dormitory on campus and his residence in Yanyuan were carefully checked for risks by the confidentiality team in the capacity of cleaners, after obtaining Wu Tong's consent.
As Wu Tong showed more and more personal value, her protection configuration also increased day by day. Now, Wu Tong's protection level is almost the same as Cheng Lao's.
Of course, this does not mean that Wu Tong’s benefits will catch up with those of an academician in a short period of time.
After all, the experts who can be selected into this level are basically top scholars who have made outstanding contributions to the country and fought for the country. They may not be as outstanding as Wu Tong for a while, but they have also contributed everything they have on the road of national development.
It's just that because Wu Tong is now leading a major national project, is responsible for the research and development and production of two top-secret materials, and has access to extremely high-level confidential information, security forces are the top priority.
However, even so, Wu Tong has now been included in the national key list and is a key protected object. In particular, now that the T5 single crystal nickel-iron alloy blade material has been successfully developed, Wu Tong's importance level will be further improved!
