Actuation system for antenna reflector with deformable reflecting surface

摘要

In the field of antenna reflectors with a deformable reflecting surface, an actuation system, with which such a reflector may be equipped wherein the reflector includes a chassis, a flexible membrane fixed to the chassis, comprises: a support fixed to the chassis, a set of deformation devices, each deformation device including a pusher element adapted to be driven in translation relative to the support along an axis, the pusher element including a part adapted to come into contact with the flexible membrane at a point to deform it, an actuation device adapted to drive the pusher element of one of the deformation devices in translation at the same time, and a selector device adapted to move the actuation device toward each of the deformation devices.

1. An actuation system configured to actuate a reflector including a chassis and a flexible membrane, the flexible membrane being fixed to the chassis such that the flexible membrane is deformable relative to the chassis, the actuation system comprising:
a support fixed to the chassis of the reflector; a plurality of deformation devices, each deformation device of the plurality of deformation devices including a pusher element adapted to be driven in translation relative to the support along a first axis, the pusher element including a part adapted to come into contact with the flexible membrane at a point to deform the flexible membrane; an actuation device adapted to individually drive the pusher element of each deformation device along the first axis in translation; and a selector device adapted to move the actuation device toward each deformation device individually, in such a manner that the actuation device is configured to individually drive the pusher element of any deformation device selected from the plurality of deformation devices in translation.
