Problems solved by technology

[0016] The present invention is to solve the problem that the angular momentum of the swivel system is too large and the angular momentum is very difficult to eliminate. It provides a pre-rotating cable device, which uses the cable to generate centrifugal force, and uses the centrifugal force to ensure that the cable is called a straight line. And generate ampere force in the process of rotation to increase or decrease the revolution speed

Embodiment 11

[0053] The electric thruster is an electric-driven space propulsion device. It is composed of an ion generator, an ion accelerator, and an electron gun (neutralizer). The ion generator decomposes atoms into ions and electrons. launch into space. Such as NASA's X3 ion thruster. In the present invention, the function is not to generate thrust, but to generate electron flow. The electrons generated by the ion generating device are not directly ejected into space by the electron gun, but pass through the cable 1, reach the electric thruster at the other end, and are ejected into space by the electron gun of the thruster. In this way, a one-way current is formed, and an ampere force is generated under the action of the geomagnetism.

[0054] Currently produced electric thrusters are equipped with ion generators, ion accelerators, and electron guns at the same time. The current generating device 5 refers to an ion generating device or an electron gun, or a complete electric thrus...

Embodiment 12

[0062] Such as figure 2 As shown, after the cable 1 and the cable 3 were released, before breaking away from the reducing rope 7 ends, the cable 1 had a clasp 6 every 100 meters, and the clasp buckled the cable 3. This clasp has opening, and after opening is opened, cable 3 is put into, and cable 3 has just been fastened. The cable can slide relative to the cable, but is always attached to the cable. This allows the cable to buckle the hawser, preventing the two ropes from colliding. Buckle 6 can be opened and closed, can be fastened at any time, and can also be loosened.

[0063] The R-value of the swivel system 19 is 30 km and the mass of the pre-swivel cable installation is 10 tons. Cable 1 length is 2km, cable 3 length is 3km.

[0064] A cable transfer system, the end of the variable diameter rope 7 of the cable transfer system has a pre-swivel cable device, the revolution and rotation planes of the cable transfer system coincide, and the included angle with the geoma...

Embodiment 13

[0066] A pre-swivel cable device, the length of the cable 1 is 2000 meters. After the pre-rotating cable device breaks away from the reducing rope 7 ends, it rotates while revolving, and the method for stopping the rotation is:

[0067] a. The midpoint of the unwound part of the cable 1 is outside the center of mass 12 of the pre-swirled cable device;

[0068] b. Then while the cable 1 is rotating, electromagnetic induction is performed when it is within 60 degrees of the vertical line of the same half cycle to generate an ampere force in the backward direction of the revolution; or: within 60 degrees of the vertical line of the opposite half cycle When inside, the power supply drives the cable to generate an ampere force in the direction of revolution forward.

[0069] A method to realize that the midpoint of the cable 1 payout part is outside the center of mass 12 of the pre-swirled cable device is as follows: Figure 4 As shown in a, part of the cable is wound by the winc...

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 providesa cable rotating system of a pre-rotating cable device; the pre-rotating cable device is used for taking away angular momentum so as to eliminate the angular momentum brought to the system in the ascending process of a spacecraft. And after a plurality of revolution periods, the pre-rotating cable device meets the system again and is in butt joint with the system for reuse. And when the pre-rotating cable device is separated from the tail end of a reducing rope, the pre-rotating cable device has an autorotation speed without increasing rotation, so that the steps are reduced. By means of the method, the rotation reducing process of the system is very simple and easy to achieve.

Description

technical field [0001] The invention belongs to the field of space, and relates to a winch, a brake, a rotating cable system, and a launch vehicle, and in particular to a pre-rotating cable device and a method for reducing rotation on the rotating cable system. The pre-rotating cable device is used to realize the rotating reduction of the rotating cable system , to help the spacecraft get into 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. [0003] The hoist is composed of a motor and a reel, and the hoist is wound with a cable to provide pulling force. [0004] The reel is composed of a motor and a reel, and its appearance is similar to that of a hoist, but the wall of this reel is very thin, which can only play the role of winding and storage, and cannot provide traction. [0005] The cable t...
