Sistema de accionamiento para reflector de antena con superficie reflectante deformable

摘要

The system has a support formed by a fixed structure (231) fixed to a frame of a reflector (20), and a set of deformation devices (234), where each device comprises a push element i.e. threaded rod (2345) driven in translation with respect to the support along an axis (X2). The element has a part to contact a flexible membrane (12) in deformation points (121). An actuating device (233) drives the element along the axis. A selection device (232) moves the actuating device toward each of the devices, so that the actuating device drives in translation the element of the deformation device.
