Chapter 784: Chapter 423: Isn’t That Our Laboratory?_2
Now...
"Even if Academician Zhao is joined by us, we’re only a total of four people. How can we possibly design a turbine!"
Yuan Haitao thought the idea was a joke.
Xue Fengge said, "Zhou Qing knows little about turbines and I’m not good at research and development either. You, Captain Yuan, also aren’t..." He paused and continued, "Ahem, only you, Captain Yuan, know a bit. It’s you and Academician Zhao, two people."
"Regardless, I think that Academician Zhao has ideas and besides, he is Academician Zhao!"
"Anyway, it’s not important," Yuan Haitao said after putting his hand over his mouth. "We can just collaborate."
"That’s right."
Their assigned task was to assist Zhao Yi. Discussing what Zhao Yi wants to do is pointless. fɾeeweɓnѳveɭ.com

Dismantling the turbine engine isn’t difficult, but the process is bothersome because some parts are heavy, and the number of parts is vast, which makes it tedious to place them separately.
By one in the afternoon, Zhao Yi and two workers had sequentially removed the most important turbine blades. There were sixty turbine blades inside the turbine engine, with each one finely made. Polishing them a bit could seemingly turn them into sharp knives.
"Turning this blade into a knife won’t be easy."
"It has really high strength."
"I tried to make one into a knife once," Yuan Haitao suddenly blurted out. Everyone turned to look at him. He sheepishly explained, "A few years ago, there was a scrapped fighter plane from the 1950s made in the Soviet Union. I took a blade from it and tried to grind it into a knife. After grinding for quite a while, I only managed to tarnish it a bit. I couldn’t grind it."
"That was a turbine blade from the 1950s. This blade is a bit substandard, but it’s surely more advanced."
Everyone else laughed and said, "Ah, I see."
"Captain Yuan, you really have ideas."
"Actually, this is a great idea, taking a decommissioned blade and turning it into a blade that will probably last forever. But grinding it into a blade might be a problem. You’d probably need professional help."
"You’d have to go to a lab that specializes in alloy materials or something like that..."
Zhao Yi didn’t participate in the discussion but listened with a smile. He also thought it was a great idea and looked at the blades placed on the ground, contemplating seizing an opportunity to take a few and grind them, preferably into the shape of a knife.
Should he ask Zhang Hongtao to custom make a set?
Fruit knives, chef’s knives, and so on, all made of high-strength nickel alloy tools. The idea seemed quite elite.
Speak of the devil and he shall appear!
Zhang Hongtao was here.
A guard outside reported it and Zhao Yi immediately said, "Let him in right away, he’s an expert in alloy materials!"
Once Zhang Hongtao entered the operation room, Zhao Yi immediately brought him to the office, treated him briefly, and then started discussing the technical issues of the turbine blades.
Zhang Hongtao was much more professional than Yuan Haitao. He hadn’t researched turbine blades, but he was very knowledgeable about them. He said, "To my knowledge, the domestically-produced aviation engines that we use now, like Kunlun and Wuhang, use a type of Nickel-iron alloy material for their turbine blades. It was the result of the Metal Research Institute of the Science Academy."
The Wuhang project team developed the turbojet engine, a project established after 2000 based on the technology of the Kunlun project team. The prototype is already in production.
"Currently, one of the major hurdles in domestic aviation engine technology is the turbine blades. The material of the turbine blades is a major issue. The Metal Research Institute of the Science Academy and the Aviation Materials Research Institute in the capital have both conducted relevant research projects and have had some progress in developing DD5 and DD6."
"However, DD5 and DD6 are both second-generation Single-Crystal Nickel Alloys. There are actually three conceivable options: Single-Crystal Nickel Alloy, Polycrystalline Nickel Alloy, and Nickel-Iron Alloy."
"From the outset, the direction set was towards Single-Crystal Nickel Alloy. The first generation of nickel alloys in our country was also Single-Crystal Nickel Alloy. Now, it’s entering the second generation, but the performance still can’t keep up, so research must continue."
Zhao Yi asked curiously, "What about the other options?"
"What we are using now is Nickel-Iron alloy because the Nickel-Iron alloy we have now has better heat resistance and higher strength. As for DD5 and DD6, their heat resistance is okay, but their strength is slightly lacking."
After finishing his explanation, Zhang Hongtao said, "Although the Nickel-Iron alloy technology in our country is better, the main direction of research is definitely Single-Crystal Nickel Alloy, because there are successful precedents-the M Country used Single-Crystal Nickel Alloy for their turbine blades."
"I see."
Zhao Yi now understood.
The current Nickel-Iron alloy manufacturing technology is better than that of the Single-Crystal Nickel Alloy, but the technology that was already available more than a decade ago has not improved or developed much since. It’s very difficult to make further progress.
The Single-Crystal Nickel Alloy is different.
The world’s top turbine blades use Single-Crystal Nickel Alloy, which sets a successful precedent. It’s important to see hope in research. Nickel-Iron alloy research direction has no reference point, and the research path can only be slowly explored. There are successful cases in Single-Crystal Nickel Alloy. You can continuously advance by following the target.
Here lies the difference between the two.
That’s why we use Nickel-Iron Alloy, but the main focus of the research is Single-Crystal Nickel Alloy.
"Single-Crystal Nickel does indeed have superior aspects."
