This train of thought that launchs aerospace spacecraft with rope of exceeding lofty or great arose about a hundred years ago, but just do not put a cord to come down in aerospace so simple.
Above all it is to should make a very long string (also be by several finer cord comprises) , pass similar wear suspension bridge the means of progressively erect cord progressively ingoing goes in aerospace, the centrifugal power that can use cord to circle the earth to carry movables is born so throws rope automatically straight, and if stand to put string from the space merely,come down, criterion the centrifugal force of cord is insufficient, the weight of its oneself can pull dimensional station from the sky, so rope of this exceeding lofty or great should grow exceedingly, beforehand appraise wants 10 thousand kilometers of 3-5 to just enough centrifugal power maintains cord to keep straightforward up this characteristic.
To assume aerospace elevator blast off bear weight, the centrifugal force of this cord must the weight that Yuan Chao crosses cord just goes, whole cord bears actually tremendous up only pulling force, launch load to also can pull string otherwise, should achieve this result simpler, as long as rope is enough grow or weight is appropriate can. As a result of cord this suffers force character up, if cord ruptures in the place that stands by the earth, broken cord can fly away up, this brings a the biggest gain: This a side that standing by the earth does not need high rate at all, because cord is standing by this a side of the earth,be pulled purely.
To reduce cord self-prossessed, maintain to be as long as the cord of several kilometers, this material must light pliable but strong, material proportion too congress causes string self-prossessed rupture greatly too, so up to now the mankind is common general data cannot support at all, in theoretic also have Xi of similar black lead only this kind of super material just comes true likely.
Black lead Xi this kind of material because and have atomic clearance drawback hardly, the intensity of material depends on only the active force between the atom of material, because this intensity can amount to the theoretical value of material, and carbolic atom because atomic weight is not great, proportion is smaller, it is one of good stuff that achieve string of exceeding lofty or great. So I beforehand 200-300 of appraise mankind future just can appear after year this kind of actual aerospace launchs a system, of course once it appears, emissive spacecraft resembles sitting really elevator is general simple, the rocket is about to proclaim retired.
