Abstract (en)
[origin: EP2451007A1] The device (12) has fixation units (19, 20) e.g. Velcro(RTM: hook and loop fasteners) to fix a multi-layered thermal protection membrane (18) with an emitter equipment (13). The membrane has elastic tensioners (23) with flexible strips i.e. Kapton(RTM: polyimide film) strips, for maintaining the membrane in tensioned state between a plane or concave active face (15) of the equipment and a space, independent from thermal expansion of the membrane and the equipment produced in a preset temperature range, when the units assure fixation of the membrane with the equipment. The preset temperature range extends from -250 degree Celsius to +400 degree Celsius. The emitter equipment is chosen from a group comprising single parabolic reflector, dual grid reflector and radiating panel. An independent claim is also included for a method for fabricating a radioelectric wave reflecting device.
