Chapter 843: Chapter 444 What Can You Do If You’re Just Naturally Smart?_3
If the weight of the engine increases, to improve the thrust-to-weight ratio, the maximum thrust must be increased; however, the thrust generated by relinquishing the high-pressure air released from the poppet valve could hardly compensate for the added weight.
Another issue is the design of the piston.
This is an extremely complex issue, as a simplistic design would surely cause the piston to wear out severely, potentially leading to problems in use. Furthermore, it’s known that the technology for continuous small pistons is also very challenging.
In Sun Lei’s original design, there were no detailed plans for the piston.
This aspect still required consultation with materials experts.
Zhao Yi immediately brought in Li Rongmao and Zhang Hongtao. To gather more ideas, he called everyone from the team to brainstorm and think collaboratively about a solution.
The others were not specialists and could only apply their imagination to speak, but laymen’s thinking is unlimited, and perhaps they could come up with better ideas.
This time, the credit went to Zhou Qing.
Zhou Qing didn’t understand the principles of pistons or the complex issues with materials. He suggested a very ingenious idea, to design the piston like a sponge being squeezed, "If the pressure is too high, it will certainly push the sponge up. Once it expands to a certain extent, air could rush through."
"Otherwise, it can’t get out!" freёwebnovel.com
His idea was immediately rejected by the materials expert.
Zhang Hongtao spoke with certainty, "There’s no such material. As long as it can be expanded by pressure, it must be porous. Otherwise, it’s like a balloon—impervious. Once it’s porous, it would burst."
"If such material existed, we would have seen pistons of this type on the market already."
Zhou Qing muttered softly, "I’m just sharing my thoughts. Academician Zhao said we could express any ideas we have..."
Zhao Yi did not dismiss the idea outright but furrowed his brows, feeling that Zhou Qing’s idea was quite innovative. Indeed, the materials were not supportive, but a more complex design might be possible, like creating the piston with a porous structure, filling it with materials like rubber and resin. When the pressure was too high, these materials could move within the pores, revealing paths to the exhaust ports.
When the pressure was insufficient, the rubber and resin would revert to their original position under the compression on the other side. ƒrēewebnoѵёl.cσm
This design could connect different stages of the compressor with small holes, but the middle would certainly not be clear, blocked by rubber or resin materials. Due to the difference in pressure on both sides, the rubber and resin materials would change position when the discrepancy was too significant.
For example, if the left side was at 10Kpa (pa, a unit of pressure) and the right side at 20Kpa, the difference would be 10Kpa.
The material in the middle of the holes would shift positions, exposing a path to one side’s exhaust port.
If the left was at 2Kpa and the right at 7Kpa, with only a 5Kpa difference, the material in the middle would change position, but not enough to reveal a path to the exhaust port.
A design with such small holes—one alone would definitely not suffice. Perhaps a dozen or more would be needed to adequately release the high-pressure gas.
Of course, the width of the holes still had to be considered.
Zhao Yi pondered for a long time before he suddenly spoke up, "I think Zhou Qing’s idea is feasible. We could design it like this..."
He briefly shared his thoughts.
Everyone listened intently, growing increasingly astonished. Sun Lei was so amazed that he opened his mouth wide and couldn’t help exclaiming, "Academician Zhao, you’re truly a genius!"
The others also chimed in, "This design is brilliant!"
"Did you base this on Zhou Qing’s idea? How do I feel it’s completely different? Is there any connection between the two?"
"This piston design is really high-tech, and it just so happens to be perfect for the compressor..."
"Academician Zhao really is Academician Zhao!"
"If other engine teams heard your idea, I bet they would be blown away!"
"..."
Amidst a flood of flattery, Zhao Yi displayed a calm smile.
Sometimes, he truly wished to keep a low profile, as appearing too much like a genius would distance him from the masses.
But what could he do?
Being a natural-born genius, what else could he possibly do?
