Abstract
A supporting structure for a solar sail of a satellite is formed by support arms which are connected in a swiveling manner with a solar panel through unfolding joints, and a film is stretched between the support arms. A longitudinal connector is arranged parallel to one side edge of the solar panel, which has support arms that are arranged in a joint direction in the plane of the film and form at least one U-shaped supporting structure between which the film of the solar sail can be stretched. Corner connectors are arranged in the interior angle areas between the longitudinal connector and the support arms. This arrangement simplifies known constructions while maintaining the existing functional safety in order to allow for achieving a noticeable weight reduction.
