Chapter 780: Chapter 422: The Most Important Thing is to Hug the Big Thigh!
Over the next two days, Zhao Yi stayed in the Power Engineering Laboratory, working with Yuan Haitao and Zhou Qing to verify the partition structure of the combustion chamber.
Yuan Haitao and Zhou Qing both felt very excited. The engine combustion chamber design had not taken into account the partition structure, or rather, the original design thought that the partition structure would not significantly impact the overall engine design. Even the combustion chamber itself was not a critical component, let alone the partitions.
Now, they were like discovering a whole new world. Changing the partition structure could actually directly improve the combustion chamber’s efficiency.
This deserved serious attention.
Additionally, Yuan Haitao and Zhou Qing felt very involved, especially Yuan Haitao. He was not very familiar with the structure of the combustion chamber, and research like this would never have considered him if it were conducted at the research base, denying him the opportunity to participate.
But now, things were different.
He participated in discussions on the partition structure design and occasionally offered his suggestions. Although he didn’t fully understand throughout the process, he felt a sense of connection with the final design.
In reality, Zhao Yi was merely taking care of their feelings.
During the process of perfecting the partition structure, he could quickly arrive at conclusions based on the system’s capability. However, he could not do everything by himself. It was not about sharing the results with others; Yuan Haitao and Zhou Qing’s contributions were still significant. They helped explain many basics and assisted in perfecting the preconditions needed for using the capability, thus playing their roles in the process.
So, Zhao Yi still took care of the two’s feelings, merely expressing his ideas and designs through discussions and questions.
Then came the verification.
At first, Zhou Qing performed rough calculations for verification, but later he simply stopped. He found that doing any calculations in front of Zhao Yi was like wielding a broadsword before Guan Gong--
Ridiculously funny!
Zhao Yi often arrived at more accurate results just by casually calculating what Zhou Qing had been struggling with for a long time.
"This is too genius!"
"No wonder he’s a top mathematician. In terms of computational power, he might be the world’s best already..."
Zhou Qing sighed quietly. ƒreewebηoveℓ.com
Zhao Yi spent about two days going through the partition structures in the combustion chamber, even making simple design modifications to the seemingly insignificant partitions at the edges.
Zhou Qing carefully recorded all conclusions and proceeded with detailed calculations.
He computed the overall performance improvement brought by the changes.
Each partition change increased performance, but to determine the overall improvement, detailed calculations were needed, involving multiple factors such as the reciprocal effect and the efficiency of the exhaust. Different work environments brought different results.
Zhao Yi also calculated seriously, considering factors from all aspects.
In the end, the two came up with different results.
Zhou Qing said excitedly, "The data I calculated shows a performance increase of 15% under maximum working intensity." Maximum working intensity referred to the full throttle of oil delivery while achieving theoretical air sufficiency.
"Is it that high?"
Yuan Haitao was incredulous. freēwēbnovel.com
"That figure is a bit too high." Zhao Yi shook his head, "I calculated the result to be around 11%."
"Even 11% isn’t low!" Yuan Haitao commented.
Zhou Qing didn’t study why there was a discrepancy in the figures, but said excitedly, "Even 10% is quite high. Most importantly, the significant improvement in the combustion chamber’s efficiency can bring higher power."
"Yes!"
Yuan Haitao nodded vigorously.
Don’t underestimate the maximum 10% efficiency improvement. Just calculating the impact on maximum efficiency, a 10% increase in efficiency meant not a 10% increase in aircraft speed, but 20%, 30%, or even higher. Because propulsion power and top speed increased exponentially.
Of course.
In reality, there were many factors affecting aircraft speed, with the combustion chamber efficiency being just one aspect. If the performance of other components was subpar, high combustion chamber efficiency would be meaningless.
This was also why the Kunlun engine team did not pay much attention to combustion chamber efficiency. They knew that higher efficiency was better, but high efficiency did not necessarily mean high power, and it might even bring other problems.
For instance, the pressure on the turbine blades’ strength.
When Zhou Qing and Yuan Haitao cooled down, they immediately started discussing this issue with Zhao Yi. A higher combustion chamber efficiency wasn’t necessarily good, as it could also mean higher temperatures, and the turbine blades that bear high temperatures and pressures might not withstand it.
Yuan Haitao mentioned the issue of turbine strength, but Zhao Yi wasn’t surprised. Even if they hadn’t mentioned it, he was planning to improve the turbine structure next.
The turbine structure was actually a minor issue for Zhao Yi, posing no difficulty for him. "Connection Law" could offer a very complete scheme for designing the turbine blades most reasonably. Even without a perfect scheme, "Supervision Law" could be employed to modify the original plan.
However, the key issue was the one brought up by Yuan Haitao and Zhou Qing: the high-temperature resistance and strength of the turbine blades.
Aircraft engine turbines worked on the same principle as automotive turbochargers. By utilizing exhaust gas and fluid to rotate the impeller, they generated power.
