Embodiment Construction

[0032] A folded solid surface reflector according to the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

[0033] The invention discloses a foldable solid surface reflector. The structure includes a large-diameter solid surface reflector (more than 3m), an unfolding arm, a two-dimensional rotating mechanism, a self-driven hinge, a locking release device and other components. The present invention has simple structure and good versatility, and can realize the double-layer folded and folded layout of the large-diameter reflector and the long unfolded arm, thereby realizing the layout of the long focal length of the antenna more than twice the height of the satellite, and bringing greater flexibility to the layout of the antenna , no longer limited by the envelope of the satellite itself. Adapting to the development of long-focus multi-beam antennas in the future, it has wide applicability and promotion a...

Abstract

The invention discloses a foldable solid surface reflector. The structure comprises a large-diameter solid surface reflector (more than 3m), an unfolding arm, a two-dimensional rotating mechanism, a self-driven hinge, and a locking and releasing device. The invention has simple structure and good versatility, and can realize the double-layer folded and folded layout of the large-diameter reflector and the long unfolded arm, thereby realizing the layout of the long focal length of the antenna more than twice the height of the satellite, and bringing greater flexibility to the layout of the antenna , no longer limited by the envelope of the satellite itself. The invention adapts to the development of long-focus multi-beam antennas in the future, and has wide applicability and popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of aerospace and astronautics, and in particular relates to a space-borne expandable solid-surface reflector, which is especially suitable for long-focus solid-surface antenna products. Background technique [0002] With the continuous development of aerospace technology and the rapid development of high-throughput satellites, higher requirements are put forward for multi-beam antennas, such as long focal length, high reliability, high storage ratio, and reliable tracking. The existing technology cannot meet the above-mentioned requirements of long focal length and high reliability under the condition of small volume and high storage ratio. Therefore, there is an urgent need to develop a solid surface reflector with simple structure, high storage ratio and long focal length. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a foldable solid surface...
