Chapter 3383 Looking for new materials
The successive completion of the thermal radiation project and the anti-radiation project gave Qin Luo a sense of urgency.
So after leaving the R&D center, Qin Luo quickly returned to Yanda Laboratory to devote himself to the research and development of parachutes.
"Professor Qin, this is the material of the parachute that we initially decided on, please have a look." As soon as Qin Luo stepped into the laboratory, a researcher soon came to greet him.
Through the work card hanging on his chest, Qin Luo knew his name——Fang Lei.
A very serious researcher, and also the deputy team leader of this project!
After receiving the materials handed over by Fang Lei, Qin Luo carefully reviewed them.
Silk, long-staple cotton, and fine linen...
These materials are so common that most parachutes today are made of them.
However, there is a key problem here.
The field of their application is completely different from the conventional field.
Ordinary parachutes only need to drag objects of tens or hundreds of kilograms.
But a parachute attached to a spacecraft is a completely different story.
It needs to hold dozens of hundreds of tons of spacecraft!
This puts high demands on the strength of the material.
The strength of the material must be high and the toughness must be good.
Otherwise, once the parachute breaks in the middle, the consequence is likely to be the ship crash!
The materials listed by Fang Lei are of high quality and low price, which are not bad, but Qin Luo himself thinks it is not enough!
Not strong enough!
Either it won't work, or it will be foolproof!
Qin Luo absolutely does not allow even the slightest mistake.
"What do you think of Professor Qin?" Seeing that Qin Luo hadn't spoken for a long time, Fang Lei couldn't help asking.
"Not enough!" Qin Luo said in a deep voice.
not enough?
Hearing Qin Luo's words, Fang Lei froze in place.
He didn't understand what Qin Luo meant.
He listed almost all the materials for making parachutes on the market, but now Qin Luo didn't say enough, which made Fang Lei feel confused.
After pondering for a long time, Fang Lei spoke again: "Professor Qin, which aspect are you saying is not enough?"
"Strength!" Qin Luo said in a deep voice, "Fang Lei, you have to know that the parachute we developed is not for skydiving."
"Instead, it is applied to the slowing speed of the spacecraft!"
"Silk, long-staple cotton, and high-quality hemp are good materials, but they are not strong enough!"
"It's no problem to support a person who weighs tens of kilograms or hundreds of kilograms, but the question is, is the spacecraft only tens of kilograms or hundreds of kilograms?"
"No, as far as I know, even the lightest spacecraft in the world today weighs tens of tons, and the slightly larger ones can even reach hundreds of tons."
"Do you think silk, long-staple cotton and high-quality linen can withstand hundreds of tons of pulling force?"
quiet……
Deathly quiet!
The moment Qin Luo finished speaking, Fang Lei suddenly fell silent.
Although he didn't want to admit it, what he had to admit was that what Qin Luo said was indeed true!
Silk, long-staple cotton, high-quality linen and other similar materials have limited strength, and it is difficult for them to withstand tens or hundreds of tons of tension!
But if you don’t use these materials, what are you using?
Suddenly, a flash of light flashed in Fang Lei's mind.
He thought of a possibility!
"Professor Qin, do you mean that we will independently develop a new type of material?" Fang Lei asked.
