Chapter 574 (1/2)

After listening to what Wang Bin said, old Qin frowned. Although he had a hunch in his heart before, Tiangong technology probably did not have artificial gravity technology. After all, if Tiangong technology had artificial gravity technology, Tiangong technology would definitely have anti gravity technology, so the aerospace aircraft and space warplanes designed by Tiangong technology would not be the same as now, We have to use pulse detonation rocket engine to send into space. Compared with anti gravity technology, these pulse detonation technologies currently used are too backward

However, when old Qin was full of disappointment, Wang Bin thought and said, ”old Qin! Although Tiangong technology has no artificial gravity technology, it is not absolutely impossible. You said that sky city has a certain gravity. I think old Qin, as the head of the official Aerospace Department, must be familiar with choosing gravity technology!

So if we can, we can use rotating gravity instead of artificial gravity. Moreover, with our human civilization, the current energy, rotating gravity, is also the best choice at present. ”

Old Qin thought about it. Indeed, as Wang Bin said, the rotating gravity system is indeed the best choice for human civilization. After all, other forms of artificial gravity, with the current capacity of human civilization, can not be realized at all.

Therefore, Qin Lao said, ”Mr. Wang, I naturally know about rotating gravity. After all, this technology appears in many science fiction works of human civilization, such as the previous wandering planet, but it is not easy to realize this technology.

After all, what we want to build is a space city of more than 100000 tons, not those space stations with limited volume. Therefore, if such a space city wants to use rotating gravity, the material requirements for the space station are high. At least as far as I know, we don't seem to have such material technology! ”

”No, Mr. Qin, if it were a few months ago, we really didn't have such technology, but now it's different. Not long ago, Tiangong technology really made a breakthrough in material technology. This alloy material not only far exceeds the materials we have mastered in many basic properties, but also far lower than the same type of materials in terms of cost What is important is that many of the most basic materials of this material are the most basic materials in the universe, such as iron, copper, aluminum, magnesium, etc. of course, there are some rare metals, but the amount required is not much, so the cost of this material is a little more expensive than ordinary iron.

Therefore, this material is very suitable for large-scale smelting. It is precisely because of this that building a megaton space city with rotating gravity system is no longer a problem in terms of materials.

Even for the shell of the 5000 ton space warship being built by Tiangong technology, we are ready to use this special alloy. It can be said that with the existence of this special alloy, we have the real capital to enter the universe. ”Wang Bin said.

”Really, that's great.” Qin said happily. After all, with this material technology, the cost of aerospace aircraft, space warships and warships manufactured by human civilization will drop sharply. At the same time, he also has a deeper understanding of the scientific research ability of Tiangong technology. After all, this is a million ton space city! The most important thing is that such a huge space city also needs to rotate at a certain speed. In this way, the centrifugal force generated by rotation is unbearable for ordinary metals, etc., while the material of Tiangong technology can withstand the centrifugal force generated by such heavy objects.

Of course, Mr. Qin didn't know that their Tiangong technology was able to develop this technology, which was entirely due to the material model provided by super God plane and Lao Huang.
