PURPOSE: A shock absorber using a permanent magnet is provided to generate a damping force and repulsive power using the effects of eddy currents and a magnetic force. CONSTITUTION: A shock absorber(100) using a permanent magnet comprises a support unit(50) and an excitation unit(90). The support unit absorbs the impact energy when an external shock is generated in a cylindrical shape. The support unit includes a composite pipe(10), a fixing pipe(20), a shaft, and a support permanent magnet. The composite pipe includes a steel panel, a copper pipe, and a pipe band. The fixing pipe is positioned on both sides of the composite pipe and fixes the state of connecting the composite pipe. The shaft is inserted into the inside of the excitation unit. The support permanent magnet is formed in the inner wall of the composite pipe and generates repulsive power when inserting the excitation unit. The excitation unit is inserted inside of the support unit and is dragged inside the support unit.

Abstract:
PURPOSE: A deployment apparatus for landing a space exploration satellite is provided to increase the internal space utilization of the space exploration satellite because the installed space of the deployment apparatus is reduced by applying a hinge rotation structure. CONSTITUTION: A deployment apparatus for landing space exploration satellite comprises a first support rod(100), a second support rod(200), and an elastic rotation unit. The second support rod is installed to restrict the rotation by a structure of the space exploration satellite. The elastic rotation unit connects the first and second support rods and rotates the second support rod against the first support rod when the restriction of the second support rod is released.

PURPOSE: A hinge device for a satellite using a shape memory alloy and a satellite with the same are provided to minimize the deployed impact of the hinge device by removing the tradeoff between a deployment impact and rigidity after deployment. CONSTITUTION: A hinge device(30) for a satellite using a shape memory alloy comprises a first bracket(310), a second bracket(320), a tape spring hinge part(330), and a shape memory alloy cylinder fixing device(340). The first bracket is attached to one end of a satellite body by a coupling member or is attached to one end of panels if a solar cell panel is made of the multiple panels. The second bracket is attached to one end of the solar cell panel by a coupling member or is attached to one end of a panel adjacent to one end of a panel where the first bracket is attached if the solar cell panel is made of the multiple panels. The tape spring hinge part is arranged between the first and second brackets to deploy the second bracket against the first bracket. The tape spring hinge part elastically connects the first and second brackets and primarily fixes the first and second brackets after the deployment. After a shape memory alloy cylinder is deployed between the first and second brackets, the shape memory alloy cylinder fixing device secondarily fixes the first and second brackets.
