Chapter 146: , The No. 1 chief please

　　 hung up the phone, Zhang Wei looked helpless.
　　 No. 1 chief could not help laughing: "I will let someone come to help you move things back, you just tell them what to take away."
　　Zhang Wei waved his hand, "Don't talk about this, let me talk about what came to me this time."
　　 Hearing this, Chief No. 1 suddenly became serious.
　　 "I heard that you have research on special ceramics?"
　　Zhang Wei····· It seems that I said this in the morning, right? Did your news spread too fast?
　　 "It's a bit of research."
　　 "Have you heard of the single crystal wide-chord blades of airplanes?" The No. 1 chief asked immediately.
　　Zhang Wei······"emmm, I have heard of single crystal hollow blades and wide chord fan blades, but I have never heard of this single crystal wide chord blade."
　　 No.1 head: "emmm～～～"
　　Zhang Wei continued: "These two are turbine blades and one fan blade, it is not the same thing at all, and are they related to special ceramics? Are these two blades made of alloy materials?"
　　 This is very embarrassing. At this time, the No. 1 chief is embarrassed!
　　 You will have no friends sincerely!
　　 Fortunately, his castle was deep enough, and he quickly adjusted it and coughed: "So what do you know about these two blades?"
　　 "There is so little to understand." Zhang Wei said indifferently.
　　 "Can you make these two blades?"
　　Zhang Wei·····Do you have any misunderstanding about a little understanding? Can it be understood?
　　 "Can't do it." Zhang Wei said suddenly without anger.
　　 "Can't you do it?" No. 1 Chief said suddenly disappointed.
　　 "It's really impossible to make such a weak blade." Zhang Wei nodded affirmatively.
　　 No. 1 head... You don’t pretend to die, right?
　　You explain, what makes such a weak blade impossible?
　　 "Don't look at me like this, I can't do it anymore."
　　 No.1 head... It seems that this pretender is killed!
　　 "Then you can do more powerful?"
　　 No. 1 chief asked, gritting his teeth.
　　 "The stronger is really no problem, but what's the use?"
　　 "What do you mean?" The No. 1 chief suddenly didn't understand.
　　 "Just literally."
　　 "What does it literally mean?" The head of No. 1 just wanted to be crazy at the moment.
　　 "You can't use it even if I made it." Zhang Wei said his hand.
　　 "We can't use it to make it? Why?"
　　 "Because your engine's power is too small, it can't take the blade I made."
　　 No.1 chief...
　　 No.1 chief...
　　 "The engine power can't move the blades?" The No. 1 head still asked some questions.
　　 "So to say, whether it is a single crystal hollow blade or a wide chord fan blade, the purpose is to increase thrust and reduce the pressure on the material itself."
　　 No. 1 chief nodded, this is easy to understand.
　　 "But the really ideal blade is actually infinitely light, and the material is extremely tough. As for thrust, it was originally the engine's responsibility. The reason why it is so complicated now is that there is only one reason, that is, the engine is too weak."
　　 No. 1 chief... Although he didn't understand what he was talking about, he always felt very reasonable.
　　 It's just that your engine is too weak, has you considered your sister's feelings? After all, Huaguo Aero Engine was developed by her.
　　 "Do you have any research on aero engines?"
　　 No.1 head asked questions again.
　　Zhang Wei····· "Aeroengine and engine are two things, OK?"
　　 No.1 head looked at him blankly.
　　 "The engine refers to all machines that can convert other energy into mechanical energy. The aero engine refers to the entire system that provides power for flight. Do you understand?"
　　 No. 1 head blinked, "¨¨Almost understand."
　　 Looking at the other person's eyes, Zhang Wei has completely given up the idea of ​​persuading the other party.
　　 "To put it simply, have you watched the game of BYD and Porsche today?"
　　 No. 1 chief immediately nodded.
　　Zhang Wei·····"You really watched it!"
　　 No. 1 head... Hey, it seems to have exposed something.
　　 "Since you watched the game, you should understand that compared to electric motors, internal combustion engines are far inferior in terms of efficiency and durability. This is determined by mechanical properties and cannot be overcome."
　　 "So what do you mean?"
　　 "If you want the engine to be strong enough, it is simple, just replace the fuel engine with a generator."
　　 "It's that simple?" Head No. 1 asked in surprise.
　　 "Simple? Do you know why no one installed a generator on the plane before this (good king's) day?"
　　 "Why?" No. 1 chief asked Congruliu.
　　 "Because there is no power source that can provide the plane with sufficient current strength, and it is also a very troublesome thing in terms of battery life."
　　 "I understand, because you have developed a lithium-sulfur battery, can you solve these problems now?"
　　 No. 1 head suddenly realized the Tao.
　　However, Zhang Wei shook his head.
　　 "No, not even a lithium-sulfur battery."
　　 No. 1 chief... So you told me that this has been nonsense for a long time?
　　 "But the lithium battery can!"
　　 No. 1 chief... Are you going to die if you pant so hard? .
