Problems solved by technology

In addition, the revolution period after the weight is separated is likely to be as long as 2.5-4 hours, and the period of the cable transfer system is inconsistent with that of the cable truss, so it is difficult to meet again
These factors make it take about 4-15 days for the cable transfer system to be able to connect the hammer again, which takes too long

Embodiment 1

[0040] Embodiment 1 (claim 1)

[0041] A cable truss such as figure 1 , 2 As shown, the cable truss is composed of a cable 1, an electric thruster 15, an electron gun 14, and a truss 2.

[0042] Truss 2 is elongated, with a length of 500 meters, a width of 10 meters, and an aspect ratio of 50. The cable 1 is straightened into a straight line, and both ends are tied to the two ends of the truss 2 and fixed on the truss 2 . There is a thin wire every 8 meters on the cable 1, and the cable 1 is tied to the truss 2. The function of the truss 2 is to ensure that the cable 1 is straightened into a straight line.

[0043] The cable 1 is a single circuit, and the electron gun 14 and the electric thruster 15 are respectively connected to the two ends of the cable 1 . The electric thruster 15 can generate electron flow, and the electron flow passes through the cable 1 to the electron gun 14 at the other end, and is launched into space by the electron gun 14 to form a unidirectional...

Embodiment 2

[0046] Embodiment 2 (claims 2, 3)

[0047] Other and embodiment 1 system, difference is:

[0048] Cable 1 is a superconducting cable, the maximum current of cable 1 is 10000A, and the length is 1000 meters. The revolution speed of the cable truss after detaching from the end of the reducing rope is 8200m / s, which can be obtained from the electromotive force formula, the voltage generated by electromagnetic induction can reach 400V, and the electric power can reach 4000 kilowatts. The geomagnetic strength is 5*10^(-5)T, which can be obtained from the Ampere force formula, and the resulting Ampere force is about 5*10^(-5)*10000*1000=500N.

[0049] This thrust is dozens of times greater than that generated by electric propulsion, and it saves dozens of times of fuel than a rocket engine with the same thrust.

[0050] When the cable truss needs to reduce the revolution speed, electromagnetic induction is required, and the ampere force generated in the opposite direction of the r...

Embodiment 3

[0054] Embodiment 3 (claims 4, 6, 7, 8)

[0055] The cable truss has solar panels with a light-gathering area of ​​30,000 square meters and a power supply of 2,000kw. The solar panels are also longitudinally and equally distributed along the cable 1 .

[0056] Such as image 3 As shown, the truss 2 of the cable truss is structurally divided into 12 sections, and two adjacent sections are connected by pivot pins, and the axial direction of the pivot pins is parallel to the long cross bar 4 . This allows the truss 2 to be easily folded. Its folding process is similar to that of a scissor lift. The length of the truss 2 is 100 meters when folded, and 1200 meters when unfolded. Each section has a hook, and each hook is respectively connected to the end of the reducing rope after being folded.

[0057] When the truss 2 is in the folded state at the end of the reducing rope of the transfer cable system 16, after the truss 2 is separated from the end of the reducing rope, the li...

Abstract

A cable rotating system working in the space faces problems that the angular momentum of a spacecraft is too large, and system rotation reduction is difficult. The invention provides a cable truss. The weight of the cable truss ranges from several tons to twenty tons. The cable truss can take away the angular momentum, so that the angular momentum brought to the system in the ascending process ofthe spacecraft is eliminated. Compared with an unpowered heavy hammer, the cable truss can generate thousands of ampere currents, hundreds of Newton ampere force is generated in an earth magnetic field, so that the time for reconnecting the cable truss to a cable rotating system is greatly shortened.

Description

technical field [0001] The invention belongs to the field of space, and relates to a winch, a cable transfer system, a carrier rocket, and an electric propulsion device, and in particular to a cable truss and its application method on the cable transfer system. The cable truss is used to reduce rotation and help spacecraft enter space. Background technique [0002] The cable transfer system includes the external transfer cable system and the space transfer cable system. The cable that pulls the load in the cable system is called the main rope. [0003] The cable transfer system is composed of a central station, two counterweights, multi-strand ropes, variable diameter ropes, 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 t...
