Space Elevator: How far from reality?

The long-awaited dream of going to the moonlight in the elevator Before sending the first airplane to Mars, people are thinking of the elevators. Although the implementation of Navroan has long been done, even in this technology, it is getting better day by day, but the Space Elevator's dream still remains.

The Space Elevator is a horizontal tower-like structure that connects Earth's land to extinction. It can be transported from earth to earth with this tower. Consequently, the conventional transportation system will not require rocket, but there will be a pool system like Elevator, with which the work will be completed. If this type of installation is implemented, then the operation of the spacecraft will not be at the same time as it would be, rather it will save a lot of fuel and money and lots of research and other Progress will start.

Space Eleventor ideas were first published in 1895. Constantin Sokolovsky, a Soviet rocket scientist, for the first time, designs a compressive space elevator design that will be 35,800 km from the surface of the Earth. This distance is the geostationary orbital distance from the surface. (Geostationary orbit is the circular orbit of the earth in the direction of the earth from the equatorial region of the Earth, in such a way that an object that travels around the earth once orbit around the earth in 24 hours, which is equal to the time of the winding of the Earth's own axis, so that if there is an object rotating in this direction, A person on the surface will always see the object in the same position.) Prepare this noble On the other, like the space elevator will apply downward pressure. But the problem of this structure is that there is no material to hold on to the extent that the pressure will be applied to such a high framework, and there is no possibility of having it in the future. People have not yet been able to build up to one km high. That's how thousands of kilometers What is the high level of imagination imaginable?

      Space Elevator Task

Then came the idea of

a stretch structure. According to this concept, the space elevator will be a flexible tower that will not apply pressure on the earth, but it will be applied to a bow to the bowel (we hang a heavy object on one side of the yarn and turn it on the other side, just like the tension). This tower Flexible ribbon or made of it and placed in the equatorial region where it is connected to the earth's surface on one side. The heavy object will be connected in such a way that the centrifugal force used by it is slightly larger than the Earth's gravity force. The effect of these two opposing balls will be reduced by the amount of single-handed force used in the space elevator, thus reducing the chance of tearing the tape. Such suggestions were published in a 1964 journal.

Space Elivator to Paint Artists

In the same year after the study was published, four American engineers analyzed this idea again and designated a balanced diameter space elevator and showed that such a space elevator was twice as strong as the most robust object in the world (graphite, diamond, quartz, etc.). Need the object The strongest objects found at that time were sufficient enough to create the moon or Mars Elevator, because the satellite and the gravity of the planet are less than the Earth. Apart from this, different models of the Space Elevator are displayed at different times. But none of these models was actually ineffective enough due to the lack of good material.

Carbon nanotube

After the invention of the carbon nanotube in the 90's, hope for new Space Elevator was created. Carbon nanotubes or CNT in short is far stronger than any conventional substance. It is almost 300 times stronger than the most solid steel rope. After the CNT inventions, the engineers again became active in the design of the Space Elite Design using this object. Not only that, various competitive events are announced with the Space Elite Design (recently a competition has been discussed in such a way that the chandeliers are transportable). Elevator: 2010. This competition was introduced in 2005 by NASA and initially announced a prize money of 50 thousand dollars for the winner of the contest. In the following years, the amount of this award was gradually increasing. In 2011, Google announced the creation of Space Elevator and established a laboratory. In 2012, an organization called Obayashi Corporation announced the construction of a space elevator by using CNT technology in the next twenty-eight years or by 2050, which would move up to 200 km per hour and move up to 30 passengers at a time.
