He requested the original designs from Sun Lei and reviewed them from start to finish. With the help of Sun Lei’s simple explanation, he almost completely understood them. Then, he continuously used the "Supervision Law" to search for problems within the design.
In addition, he would also apply the "Correlation Law" to identify areas in the design that affected the compressor, turbine, and other components. He would then make appropriate adjustnts or identify the source of the issues.
Once he started looking, a great many issues surfaced.
Listing all the issues was an extrely complicated task on its own.
Zhao Yi was very patient. Compared to complex mathematical proofs, the current content was much simpler. So minor issues were simply recorded. A combined use of the "Connection Law" and "Supervision Law" could imdiately resolve these problems. As he recorded issues, he also drafted solutions.
However, there were still over thirty problems that could not be directly resolved through causal thinking.
Zhao Yi rely recorded the problems, also assessing their difficulty based on the energy consumption of their usage as well as other factors. Those for which conditions could be determined were solvable, although they required a high energy expenditure.
These could be discussed with Sun Lei.
A few other issues required coordination with the operation of other components, which he would consider solutions for later.
Zhao Yi stayed busy until 3 a.m. that night, only then lying down on the bed to sleep. The next morning, he got up and went to the Power Engineering Laboratory, where he imdiately pulled Sun Lei into discussions regarding the design.
It was Sun Lei’s first day at work.
He thought he would start by getting familiar with the environnt and eting others, but unexpectedly, he was imdiately dragged by Zhao Yi to study the design. Rembering the problems in his design, he felt a bit guilty and couldn’t help but wonder whether he should co clean to Academician Zhao.
"There are so many problems with the design; maybe Academician Zhao hasn’t realized? That’s right, specialization matters, he hasn’t worked on compressors before, the stability solutions, those were only heard from yesterday..."
Sun Lei, with mixed emotions, followed Zhao Yi into a small eting room, where they sat at a table in the front.
Zhao Yi handed over a docunt to him.
Sun Lei took it with puzzlent and before he had the chance to open it, Zhao Yi handed him another docunt—it was the design proposal from the day before.
"You compare them first," Zhao Yi said.
"Okay."
Sun Lei began digging through the two docunts, his expression rapidly shifting from confusion to shock. He initially looked at just the first page, but then quickly flipped through to the second page, the third page...
He quickly turned over more than a dozen pages, then randomly picked a marked issue for a detailed review.
Eventually, Sun Lei couldn’t help but look up, his face filled with surprise as he looked at Zhao Yi, "This... Academician Zhao... did you write all this?"
"Yeah?"
Zhao Yi nodded, puzzled.
"Really?"
"Yes?"
After staring at each other for quite so ti, Sun Lei took a deep breath and said, "Academician Zhao, not only have you identified the issues, but you’ve also written so many solutions, all these... these..."
He was at a loss for words for a mont.
Zhao Yi said calmly, "Just take a look first. I also don’t know if it’s all correct. There are so issues I still don’t have good ideas for; we still need to discuss them together."
"...Okay!"
Sun Lei was truly shocked. He couldn’t believe that after Zhao Yi reviewed the design and spent just one night, he ca up with so much. Identifying problems and devising solutions in an unimaginable work efficiency.
He thought with a wry smile, "I’m really foolish to think that Academician Zhao wouldn’t understand. The one who doesn’t understand is !"
"With Academician Zhao’s level, he could easily handle the design on his own. He probably consulted professionals just for reference."
"Phew~~~"
Sun Lei took a deep breath to steady his emotions and began to read in earnest.
Zhao Yi sat quietly to the side, suddenly realizing that he might be expecting too much from others. What he had done in one night could take Sun Lei a day just to go through.
"Forget it, I should check on the others."
He shook his head and said to Sun Lei, "You should digest this stuff for the next couple of days, run through it from beginning to end. Those small solved issues, just be aware of them without concerning yourself too much. Focus mainly on the unsolved ones, see if you have any concrete ideas..."
After speaking, Zhao Yi walked away.
Sun Lei affird and began reading closely.
...
Ti flies.
For two weeks straight, Zhao Yi and Sun Lei discussed the design issues. Sun Lei’s foundation was indeed very good; as long as it was related, he understood it.
Just for the design of the compressor blow-off valves, he could na several types.
Sun Lei’s extensive expertise was of great assistance to Zhao Yi. Together, they discussed the unresolved issues, swiftly resolving most of them, leaving only two particularly challenging ones.
One was the excessive length of the blow-off duct.
If the blow-off valve’s exhaust was to be placed alongside the turbine exhaust, then a lengthy, slender duct would be needed. The most significant impact of such a long duct would be the need for extra material on the engine’s external layer.
This would undoubtedly increase the engine’s weight.
That was fatal.
One of the critical performance trics for aviation engines—the so-called ’thrust-to-weight ratio’—refers to the maximum thrust compared to the engine’s weight. Typically, turbofan engines have a thrust-to-weight ratio exceeding 7. The Kunlun engine’s ratio ranges between 7.5 to 8, while the world’s top engines exceed a ratio of 10.
