Infrastructure: Start to Repair The Elevator in Mount Everest

Chapter 291

At this moment, when Li Qi said the question he had prepared, everyone couldn’t help but fell into a period of contemplation.

But Director Li became anxious.

Time!

Time is already precious now, but now Director Li looks at his watch and it is already ~ almost 5 in the afternoon.

Director Li was anxious, and quickly broke An-Jing:

“Everyone, you guys, now that the thrusters, cables, and measurement centers have begun to have preliminary results, we can discuss the issue of pulleys and bearings, but I would like to ask you.”

“Can the car of Plan No. 2 be made first?”

“This way we can also save a lot of time.”

With a snap, after listening to Director Li’s suggestion, Su Mingyu, who was still looking thoughtful just now, immediately patted his forehead:

“Yes, yes, I am confused!”

“Why forgot the time again, Director Li waited a moment, and a few of us immediately reviewed the car design!”

“…”

With Su Mingyu taking the lead, many experts soon gave unanimous answers.

Experts believe that the car design of the No. 2 scheme is simple and reliable, and the first draft meets the requirements of direct manufacturing.

With the result, Su Mingyu came directly to Director Li.

After apologizing first, Su Mingyu took the drawing and said with serious eyes:

“The car can be manufactured. The main structure of the car in the No. 2 plan is aluminum alloy, and the supporting structure such as the keel is titanium alloy. Problems facing the space environment.”

“Director Li, we delayed, and now you can start the workshop.”

After that, Director Li couldn’t wait at this moment, and immediately took out his mobile phone:

“Help me inform the processing workshop. The design draft and construction drawings of the car part have now been confirmed. Yes, all the information has been reviewed by the expert group. I will immediately return it to the design institute.”

“Yes, speed up the construction progress.”

“receive.”

After speaking, the Jiuquan Command Center was about to hang up the phone immediately, but at this moment Director Li’s eyes flashed, and he immediately yelled anxiously:

“Wait. Don’t hang up, don’t hang up.”

Under the other’s doubts, Director Li at the moment said quickly:

“Tell the workshop that it is necessary to pay attention to the bearing of the car cabin and the roller skate part. These materials have not been determined. Now only the car cabin is processed, and the stability of the later combination with the bearing part must be considered.”

“Yes, exactly.”

After hanging up the phone, Director Li immediately took the chief designer and the finalized car cabin to the communications department.

The remaining experts also returned to the quiet discussion.

Looking at everyone, Li Qi couldn’t help but move his gaze, and began to slowly ask the experts:

“Everyone, do you need us to contact the staff of the institute?”

Hearing Li Qi’s words, Su Mingyu couldn’t help showing a wry smile at this moment:

“Mr. Li, it is not difficult to say that it is difficult. In fact, when we discussed in private just now, we already thought of how to solve the material problem of the pulley.”

“Tpu. Using this material to make pulleys should be able to withstand the second speed of the universe.”

“Tpu?”

Listening to Su Mingyu’s words at this moment, Li Qi couldn’t help but feel happy:

“Professor, is it difficult to obtain this kind of material?”

At this time, following Li Qi’s words, an expert next to Su Mingyu slowly stepped forward and said:

“Mr. Li, hello, I am a professor at the University of Aerospace Engineering, my surname is Ma.”

Listening to the name of the other party saying hello, Li Qi couldn’t help but move his eyes at this moment.

The University of Aerospace Engineering, it seems that this is just another major.

At this moment, Professor Ma stepped forward and explained in a professional tone:

“Mr. Li, this tpu material, his scientific name is called’thermoplastic polyurethane elastomer’. As the name implies, it is originally through the weakening of the intermolecular force in the molten state or the solution state, and there is strong intermolecular force connection after cooling or solvent volatilization. Produced together, can restore the original solid performance during use.”

“Domestic research institutes have now mastered the manufacturing technology, and tpu has the advantages of excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, and low temperature resistance…”

“…”

Listening to Professor Ma’s introduction, Li Qi at this moment couldn’t help but look at Su Mingyu excitedly:

“This kind of tpu material is really amazing, Professor Su, what are you still worried about now? We only need to solve the bearing problem and we can start manufacturing immediately!”

At this time, as Li Qi’s excited voice fell, Su Mingyu looked up and revealed a wry smile:

“Mr. Li, it seems that a problem has been solved now, but if the problem of bearing materials is not solved, then everything is empty talk.”

As Su Mingyu finished speaking, Professor Ma, who just made popular science like Li Qi, continued to speak:

“Yes, President Li, at the second cosmic speed, it is difficult for the steel ball in the bearing to be intact under high-speed friction. After the violent friction, the intense high temperature generated by the bearing will cause internal melting, and even cause the final The inside of the bearing is directly turned into molten iron.”

“It’s like the electric drill commonly used by Mr. Li in your projects. No matter how hard a bit, when drilling a target, it will generate high temperature and smoke or even melt due to high-speed friction.”

…….. .. …….

“There is a material that can avoid this situation, and that is to use aerospace materials…”

“However, if high-temperature-resistant aerospace ceramic materials are used, this material lacks ductility, which may cause derailment during the activities of pulleys and cables.”

Listening to Professor Ma’s words, Li Qi was stunned at this moment.

“It also needs the advantages of high temperature resistance and a certain degree of ductility. Isn’t this a paradox?”

As Li Qi spoke, Professor Ma nodded helplessly:

“Mr. Li, you can understand it this way. The issue of bearing materials is really a paradox.”

At this time, Li Qi was a little surprised when he heard the words, and once again looked at many experts to ask questions:

“Can’t the institute provide similar materials for us to screen?”

Su Mingyu shook his head after hearing this:

“No. Even contacting the institute will not help.”

“In the current known materials, there is no material that can fulfill these two opposite requirements.”

“unless……”

Just as Su Mingyu was hesitating, an expert who reserved an inch, said with a cold expression on his face:

“Unless we can create a new material!”

Listening to these words, Li Qi couldn’t help falling into silence.

Where is the time to choose a new material? NS.
