Embodiment 11

[0079] A cable formation is composed of two cable systems 7, that is, N=2. The transfer cable system 7 refers to the external transfer transfer cable system 7 or the space transfer cable system 7. The transfer cable system 7 has a main rope 6, and the main rope 6 is used to move the traction load 11 inwardly or outwardly.

[0080] The two orbits 1 have an encounter area 4 where the two cable systems 7 appear simultaneously, where the distance between the centroids of the two cable systems 7 is 180 km, and the difference in altitude is less than 30 km.

[0081] Such as figure 1 As shown, the encounter area 4 is in the middle of the perigee point 3 of the revolution orbit of the two transfer cable systems 7 . The distance between the perigees of the revolution orbits of the two cable systems is 600km, and the distance between the apogees is 1200km.

[0082] The included angle between the connection line between the center of the earth in the encounter area 4 and the line betwe...

Embodiment 12

[0087] The formation has 3 transfer cable systems 7, that is, N=3, such as image 3 shown. The rotation plane of each cable system 7 coincides with the revolution plane; the revolution track 1 of the centroid of each cable system 7 coincides, and each cable system 7 is arranged front and back. Therefore, the revolution periods and revolution speeds of the respective switchable cable systems 7 are exactly the same, and the latter switchable cable systems 7 follow the first switchable cable system 7 to advance. The encounter area 4 is the perigee 3 of the revolution track 1 of each cable system 7 .

[0088] For the formation whose revolution orbit 1 coincides, the encounter area 4 is everywhere, and the perigee 3 is the most ideal place for docking with the launch vehicle. Therefore the area of ​​encounter refers only to the perigee.

[0089] The first transfer cable system 7 is at the front of the formation, the second transfer cable system 7 is at the second position, and t...

Embodiment 13

[0096] Each cable transfer system 7 has a quick-diameter-changing device. The quick-diameter-changing device has a hoist that is an energy-dissipating hoist. The energy-dissipating hoist winds the main rope 6 and pulls the load 11, which can quickly move the load outward.

[0097] Such as image 3 The 1st and 2nd conversion cable system 7. The first transfer cable system 7 is at the front of the formation, the second transfer cable system 7 is at the second position, and the third transfer cable system 7 is at the end.

[0098] The rotation directions of the first and second cable transfer systems 7 are the same, and they all rotate counterclockwise. The so-called revolution and rotation directions refer to clockwise or counterclockwise directions. Both systems either revolve and rotate clockwise, or revolve and rotate counterclockwise.

[0099] The spacecraft 11 breaks away from the lower point at the end of the main rope 6 of the first transfer cable system 7 . The rotat...

Abstract

A cable rotating system working in the space faces the problems that the angular momentum of a spacecraft is too large, and rotation reduction of the cable rotating system is difficult. The working process of outward-moving the cable turning system is very fast, but a main rope released is very long, the occupied space is too large, and the possibility of touching the ground exists. According to the cable turning system formation provided by the invention, two or more than two cable turning systems are combined, so that the angular momentum brought in the ascending process of a spacecraft canbe greatly reduced, the difficulty of rotation reduction is greatly reduced, and meanwhile, the occupation of an airspace is greatly reduced. By utilizing the technology, the formation can efficientlyand quickly realize the ascending process.

Description

technical field [0001] The invention relates to the fields of rocket launching, aerospace, satellites, etc., and in particular relates to a cable transfer system formation, which uses the formation to help rocket launch and spacecraft to enter space. Background technique [0002] The orbits of most satellites are elliptical orbits. The closest point of the elliptical orbit to the center of the earth is the perigee, and the farthest point from the earth is the apogee, and the line connecting the apogee and the perigee passes through the center of the earth. [0003] The difference rate refers to the percentage of the "maximum value / minimum value-1" of a set of values. For example, the difference rate of the three numbers 88, 92, and 90 is: 92 / 88-1=4.546%. [0004] The cable transfer system includes the external transfer cable system and the space transfer cable system. The center of mass of the switchover system is near the central station. [0005] An external transfer ca...
