Chapter 400 Who told you? !
When Jiang Liqun saw Li Yang taking out the test questions from the file bag, the corners of his mouth raised so high that they almost reached his ears.
He no longer paid attention to Li Yang.
Because no one except him and those old guys who have been involved in this field can answer this question.
As for Li Yang...
Even if you give him another ten or twenty years, he may not be able to figure out even one or two things.
He kindly reminded.
"You can also come forward and help solve the problem together, so as to avoid accusing me of bullying the weak."
"If we pool our wisdom, maybe we can come up with a solution..."
Done.
He said no more, turned around and walked towards his workstation.
Instead of wasting time here, it is better to continue studying the problems you encountered before.
Think about it by the way.
The next step is how to transform this laboratory and recruit researchers.
I didn't expect that...
By coming to Yuwei, you may actually get a top-notch laboratory for free.
This time I came to the right place!
After Jiang Liqun left, Zhao Ze and others swarmed over, sighing and looking worried.
"Alas, Mr. Li, you shouldn't have agreed to Jiang Liqun's request. He just thought you were young and inexperienced and easy to deceive, so he deliberately did something bad to you."
"Yes! We have read the questions in the file bag a few days ago. They are simply not something that a human can solve. I guess even Jiang Liqun himself can't solve them."
"Let's think of a solution together and use everyone's talents to see if we can solve the problem! Otherwise, Engineer Li will really lose this laboratory to him..."
"..."
Listening to their comfort and concern, Li Yang was deeply moved.
But at the same time, there is also some sadness.
Do you all have so little confidence in yourself?
I haven't even started to solve the problem yet, but I'm sure I can't answer it...
But it’s normal to think about it.
In their opinion, Li Yang's current knowledge base on aircraft engines is definitely beyond their reach.
What's more, Jiang Liqun is currently researching the so-called pulse detonation engine.
They have heard of this stuff.
However, there are only a handful of institutions that actually conduct research in this area.
Many researchers believe that this is an unrealistic research direction.
Or.
The investment is far greater than the return, it's not worth it!
Actually they know.
The main reason is that this is a brand new field, and many difficult and complicated problems will inevitably be encountered during the research process.
No one likes to take the initiative to open up a new road. Most people want to continue walking on the original road and transform and upgrade it.
Li Yang took out the test questions from the file bag.
There are not many questions, only five or six.
He looked at it carefully, and then a faint smile appeared on his face.
The test questions are indeed somewhat difficult.
Of course, this is for Zhao Ze and the others...
But for Li Yang.
He felt that the questions randomly asked by the system were simpler than those when he was studying in the system space before.
When Zhao Ze and his friends saw the test questions, they felt a sinking feeling in their hearts; indeed, they were the same questions they had done before.
They turned to look at Li Yang, only to find that there was a smile on his face?
This……
Could it be that he was so angry and laughed because of the difficulty of the question?
Zhao Ze was about to say something when Li Yang slowly read out the question.
"Although the concept of PDE has been verified in the laboratory, the initiation, control and maintenance of detonation are still difficult problems. Please propose several solutions to try to solve these problems..."
He now understood why Zhao Ze and the others had said that before.
I'm afraid Jiang Liqun himself doesn't have the correct answers to the questions here.
Because these test questions are not really problems.
Rather, it is the difficulty that exists in PDE and cannot be solved yet!
Jiang Liqun turned these technical difficulties into problems.
He wanted to ask questions to see what other people thought.
have to say.
Not only is the other party not obsessed or insane because of his research on the detonation aviation engine project, he is also extremely smart.
Seeing that Li Yang didn't say anything for a long time after he finished reading it, Zhao Ze guessed that he probably couldn't solve it either.
Can't help but.
He sighed.
"Mr. Li, people make mistakes and horses stumble."
"We lost to Jiang Liqun this time, but that doesn't mean he won."
"Next time, after you have studied the theoretical knowledge of aircraft engines, you will definitely be able to catch up and defeat him."
"Don't be discouraged, you are still young and have plenty of time and energy!"
Zhao Ze's words brought Li Yang back to his senses.
He smiled softly and said.
"Who said I missed?"
"There is actually no clear answer to this question, but I do have an idea..."
Hear the words.
Zhao Ze and the others looked stunned and dazed.
Looking at the expressions on each other's faces that didn't seem like a joke, they were a little confused.
Isn’t Li Yang a newbie in the field of aviation engines?
Even they had no idea about this test question, but the other party said he had an idea?
real or fake? !
Without waiting for them to ask further questions, Li Yang spoke on his own.
"People who often study PDE know that rapid and reliable detonation is one of the most important issues for PDE to be practical, because high operating frequency and repeated ignition times are the basic requirements for the normal operation of PDE."
"And if we want the PDE to detonate reliably, be controlled freely and at will, and keep it in a stable range..."
"I think that using the process of transition from deflagration to detonation, or DDT, would be a feasible solution."
"I have had the chance to read some information and documents before, including some foreign documents. Most of the previous researchers' research on initiation and the transition from deflagration to detonation was conducted in stationary gases, and most of them used very long shock tubes. In fact, the length of PDEs is generally no more than two meters."
"These tests and experiments are almost all the results of a single detonation in a mixture with uniform concentration and no temperature gradient, which is almost completely different from the situation of multiple detonations."
"In addition, the actual operating frequency of PDE is very high, and the mixed flow velocity is very fast. The results at low frequencies are difficult to use as a design basis for high frequencies."
"From these many unfavorable conditions, it can be concluded that the PDE should be able to detonate reliably, be controlled freely, and have stable deflagration."
"We can try to use the detonation energy, DDT method, DDT enhancement, and the transition of detonation from a confined environment to an unconfined environment."
"Maybe we can find a suitable solution from these methods!"
After saying so much in one breath, Li Yang felt a little thirsty.
He walked to the side, took a bottle of Wahaha mineral water from the shelf, and unscrewed the cap.
"Gulu gulu."
The 596 ml bottle of mineral water was instantly empty.
When he came back, he found that Zhao Ze and the others were still confused, as if they had turned into wooden men.
Li Yang laughed and was about to look at the second question.
Out of the corner of my eye, I suddenly caught a glimpse of a shadow in front of me.
Look up.
Jiang Liqun came here quietly at some point.
His bloodshot eyes were filled with surprise and astonishment.
Look at Li Yang.
The expression on his face was full of contradiction and disbelief.
a long time.
He spoke in a hoarse voice.
"Who told you? Who told you all this?"
"It must be Wu Xingguo, right?"
“It must be him!!!”
