Embodiment 1

[0041] A revolving cable system, the revolving cable system carries a weight. The rotation reduction method process of this swivel system is:

[0042] a. The cable (3) end of the cable transfer system pulls the weight (11) and moves outward;

[0043] b. When the radius of rotation reaches a certain value, the weight breaks away from the end of the cable (3) at the upper point and revolves around the earth (8). Due to the high revolution speed of the heavy hammer after disengagement, the period is long.

[0044] c. After 80 revolution cycles of the cable system and 78 cycles of the weight, the cable system and the hammer (11) meet again, and the cable system is reconnected with the hammer;

[0045] Unpowered heavy objects can achieve the task of reducing spin, but it takes a long time. The advantage of the heavy hammer is that it does not depend on the geomagnetism and is suitable for any orbit, such as polar orbit and high orbit.

Embodiment 2

[0047] like figure 2 As shown, the transfer cable system 5 has a weight, and the weight is the self-rotating cable 1. At the same time, the self-rotating cable is used as the counterweight 4 of the cable transfer system. The counterweight of the self-rotating cable and the switching cable system rotates around the central station 2 . The mass of the rotating cable is 20 tons.

[0048] like image 3 , the rotation reduction method of this cable system is:

[0049] a. The self-rotating cable 1 is at the end of the cable and is in a folded state. The counterweight 4 moves inward, and the rotation cable moves outward. The so-called folded state refers to the state after the power device is folded, retracted or wound, such as the folded state of the solar panel, the folded state of the rotation cable 1, and the state after the cable is wound.

[0050] b. When the rotation radius of the rotation cable reaches 35km, the rotation cable is separated from the end of the cable 3. W...

Embodiment 3

[0058] A cable transfer system 5, the heavy object 1 is a cable truss, and the weight of the cable truss is 20 tons. The revolution speed of the cable system is 7900m / s, and the period is 90 minutes. like figure 2 As shown, the process of its derotation method is:

[0059] a. The cable truss 1 is in a folded state and is pulled outward by the end of the cable.

[0060] b. When the turning radius reaches 35km, the cable truss is separated from the end of the cable 3 at the lower point. The cable transfer system revolves counterclockwise, the revolution speed is 7900m / s, and the linear speed when the cable truss is detached is 20m / s, so the revolution speed after detachment is 7880m / s, which is still counterclockwise.

[0061] The cable truss 1 is unfolded and straightened so that the cables become straight lines;

[0062] During the revolution, the cable is perpendicular to the direction of the geomagnetic field and the forward direction of the revolution, and the cable ge...

Abstract

In order to solve problems that the angular momentum of a spacecraft is too large and system rotation reduction is difficult in the cable rotating system working in the space, the invention provides arotation reducing method. The angular momentum of a cable rotating system is eliminated through a weight carried by the cable rotating system. The cable rotating system throws out a heavy object, sothat the angular momentum of the heavy object part is lost, the angular momentum of the cable rotating system is kept at a low level, the angular momentum is prevented from being too large, and the purpose of rotation reduction is achieved. The heavy object is generally a powered device, and the power device can generate power, so that the revolution speed of the heavy object can be adjusted, andthe heavy object is reconnected by the cable rotating system as soon as possible.

Description

technical field [0001] The invention belongs to the field of space, and relates to a winch, a brake, a cable system, and a launch vehicle, in particular to a cable system with heavy objects, and a method for reducing rotation of the cable system, which helps spacecraft enter space. Background technique [0002] The orbits of most satellites are elliptical orbits. The point of the elliptical orbit closest to the center of the earth is the perigee, and the point farthest from the earth is the apogee. Perigee and apogee are collectively referred to as apse. [0003] The cable transfer system is composed of a central station, two counterweights, cables, etc. It revolves around the earth with a revolution speed of about 7.9km / s and a total mass of more than 100 tons. The cable system rotates while revolving. The center station is located near the center of mass of the system, and the two counterweights rotate around the center of mass on both sides of the center station. Cable...
