Abstract:
PURPOSE: A solar panel unfolding apparatus for a satellite is provided to smoothly fold and unfold solar panels without lateral movement and to minimize cracks even if several folding and unfolding tests are implemented. CONSTITUTION: A solar panel unfolding apparatus for a satellite comprises a first hinge unit, a first unfolding member(200), a second unfolding member(300), and a second hinge unit(400). The first hinge unit rotatably connects a satellite body(10) and a solar panel(20). The second unfolding member is coupled to one side of the satellite body and has a hollow shape. The second unfolding member is coupled to one side of the solar panel corresponding to one side of the satellite body and has a channel shape to overlap the first unfolding member. The second hinge unit is arranged between the first and second members to fold and unfold the first and second members.
