Embodiment Construction

[0025] This embodiment is a vector propulsion device for rotational motion control of a space tether system.

[0026] Such as figure 1 As shown, the sub-satellite 1, the tether 2, the mother satellite 3, and the motion state sensor 4 constitute a rotating space tether system that has completed the deployment stage. A tether release device and a braking device are installed on the mother satellite 3 to ensure that the tether system is deployed smoothly and quickly. In order to avoid the mutual influence between the release of the tether on the parent satellite 3, the braking device and this embodiment, this embodiment is installed on the child satellite 1. In addition, when the space tether system is used for satellite orbit change and space load transmission tasks, the mass of sub-satellite 1 is generally smaller than that of parent satellite 3. To produce the same control effect, the control required to install this embodiment on sub-satellite 1 less force. The motion stat...

Abstract

The invention discloses a vector propulsion device for controlling the rotational motion of a space tether system. The vector propulsion device is arranged on a single-ended star of the space tether system, can rotate and provides variable-direction vector thrust for the system. A rotating wheel drives propellers to rotate by 360 degrees along a satellite and tether connecting plane in the direction outside a rotating plane of the space tether system by taking a connecting point of a sub-satellite and a tether as a center so as to control the out-of-plane propelling angle of the propellers, and the in-plane movement and out-of-plane movement of the space tether system are controlled by controlling the thrust direction instead of installing a plurality of groups of propellers; a hydraulic rod drives the propellers to deflect by 90 degrees in the rotating plane of the space tether system with the propeller fixing seat mounting shaft as the center so as to control the in-plane thrust angle of the propellers, so that the axis of the propellers passes through the mass center of a satellite, and the influence of thrust on satellite attitudes at the two ends of the space tether system isreduced. The propulsion device on the single-ended satellite of the space tether system is utilized to realize the control of the rotary motion, so that the control is more accurate.

Description

technical field [0001] The invention relates to the technical field of space tether system equipment, in particular to a vector thruster device that provides thrust for the control of the rotational motion of a space tether system. Background technique [0002] With its unique structure and performance, the space tether system has broad application prospects in many fields such as earth observation, satellite orbit change, space debris removal, space load transmission, and artificial gravity. Compared with traditional spacecraft, the space tether system mainly uses the principle of electromotive force and momentum exchange to complete various tasks during orbital operation, which can greatly reduce fuel consumption. However, because the space tether system faces a complex environment in space, and the spacecraft itself is an underactuated system, it is often necessary to install thrusters to provide auxiliary thrust for the system to realize the motion control of the space t...
