Chapter 111: Pydd6
The meeting ended. Jiang Yang sat in his seat and wearily rubbed his forehead, then resolutely stood up.
He knew that things were not over yet, and now was not the time for him to rest.
Beside him, Gu Changshan also stood up.
Jiang Yang looked at him: “Let’s go, prepare the training for me.”
In the previous cycles, it was always like this. After the meeting ended, Jiang Yang would prepare for the moon landing.
This time, however, Gu Changshan shook his head.
“No, no training.”
“Oh?”
Gu Changshan looked at Jiang Yang seriously: “In the previous cycles, because of your cost and sacrifice, we have already obtained enough intelligence. In this cycle, you don’t need to go to the moon anymore, you can rest well.”
Jiang Yang was a bit anxious: “But the situation in that passage and the floating city are only known to me, only I have seen it personally. Without my guidance, can the astronauts get there?”
“They are all the most excellent warriors. With the intelligence you provided, I believe they can definitely complete this mission. And…”
Gu Changshan paused, his expression becoming even more solemn: “In this cycle, you cannot take any risk.”
Jiang Yang was slightly stunned, and immediately understood in his heart.
Indeed, I cannot take risks.
If I ultimately still die on the moon, then even if the astronauts ultimately complete the mission to destroy that floating city, the cycle will still start, and their sacrifice and everyone’s effort on Earth will be in vain.
For this moon landing, I cannot go.
“Rest well.”
Gu Changshan gently patted Jiang Yang’s shoulder and turned to leave.
……
Fengshan Superconducting Laboratory Building was brightly lit.
In the meeting room, experts from various disciplines such as superconducting, refrigeration, machinery, etc., from all over the nation gathered together.
Lu Zhaoming sat at the conference table, his expression full of solemnity.
For this meeting, he was not participating as a theoretical physicist, but as the chief science consultant of the Apocalypse Project Command, participating and presiding.
“……The above is the background and specific demand of our mission this time.
Everyone present is an expert in the relevant fields, please speak freely if you have any opinions.”
The meeting room immediately had a slight commotion, but it subsided after a moment.
Under Lu Zhaoming’s hosting, group discussions began. Finally, an expert raised his hand as representative.
“The core of this mission is actually divided into two parts: first, superconducting material; second, refrigeration equipment.
Among these two parts, the refrigeration equipment is the most critical.
And the refrigeration equipment will be subject to ‘corrosion’ by that unknown existence suspected to be a negative matter field, so the structure of this entire device must be like this:
The outermost layer must be completely covered by superconducting material, it is the armor of this entire device;
Inside the superconducting material is the refrigeration device, its outer layer must be kept at extremely low temperature to ensure that the superconducting material is at the ‘superconducting’ temperature, so as not to quench;
Further inside is the crew cabin and the power source.
In the case where electricity cannot be used, based on the working principle of the refrigeration machine, it is also possible to complete this process using other forms of energy.
Then the alternatives are the following three: heat engine, manpower, and gravitational potential energy.
Heat engines include diesel engines, gasoline engines, kerosene engines, etc., all equipment that obtains motivation through fuel combustion belongs to the category of heat engines.
But heat engines will cause a serious problem: they themselves will release a large amount of heat, which contradicts the extremely low temperature that the superconducting material must maintain.
I think heat engines can be eliminated.
Next is the manpower of the astronauts.
They can drive the compressor and refrigerant operation with their own manpower inside the refrigeration machine, creating a sufficiently low temperature for this entire device to ensure that the outermost superconducting material does not quench, ultimately achieving the effect of armor.
And, according to existing intelligence, that lunar underground passage has a downward slope, and this entire device must have a high mass, thus possessing certain gravitational potential energy, which can also be utilized.
Of course, how much specifically, and how to integrate the manpower of the astronauts and gravitational potential energy still needs specific calculations.”
Lu Zhaoming was silent for a moment and asked: “Using manpower and gravitational potential energy two kinds of energy to replace electricity, in a vacuum environment with an average temperature of minus 30 degrees Celsius, control the temperature of this device to at least minus 180 degrees Celsius……can it be done?”
He knew that the working principle of the refrigeration machine is actually very simple, nothing more than using external energy to apply pressure to the refrigerant, forcibly causing it to vaporize or liquefy, and using the heat absorption and release in the vaporization and liquefaction process to achieve temperature control.
Whether it is the refrigeration machine being discussed now or ordinary household air conditioners, they are all based on this principle.
But a refrigeration machine that can reach such low temperatures is obviously different from ordinary air conditioners, it already belongs to the category of real scientific devices.
Extremely precise and complex, with very large volume and mass.
Relying only on manpower and gravitational potential energy to make it work stably, this is probably harder than going to heaven.
The voice of the expert who was the representative also became a bit low: “This is just the overall design idea. Whether it can actually be done…”
He paused, his voice becoming firm: “It can definitely be done.”
“Good. The refrigeration device will be handled this way for now. Next is the superconducting material.”
Lu Zhaoming’s gaze turned to the group of material experts: “It must meet the following characteristics.
First, production capacity high enough, able to produce enough quantity to cover the entire refrigeration device in a short time, and we must also consider the possible damage to the superconducting material.
Second, it must have sufficient toughness itself, preferably with certain wear resistance. Because no matter how we design it, this refrigeration device will always have parts that directly contact the ground of that passage.
Third, easy to store, easy to access, easy for astronauts to operate.
Fourth, the temperature upper limit should be as high as possible. The higher the quench temperature, the lower the requirements for the refrigeration device, and from an engineering perspective, the easier it is to achieve.
Based on these four characteristics, combined with existing production capacity and superconducting material properties, which material do you think is the most suitable?”
After a brief but intense discussion, another expert stood up as representative.
“The superconducting material that meets these traits is only one kind, PYDD-6.”
That expert said: “This is a compound based on bismuth strontium alloy, with a quench critical temperature of -190 degrees Celsius in vacuum.
But the problem is that this material is on the verge of elimination due to insufficient comprehensive performance, many production lines have been demolished, and current global production capacity is low.
Our country currently has only 6 manufacturers with production capacity. To produce enough quantity in just four or five days, our production capacity needs to be expanded at least five times.
