Abstract: The invention concerns a device (10) for the superplastic forming of a blank (16) in a mould (20) with a lower mould (14) and an upper mould (12) into a component, in particular a suction component (46, 54), with a three-dimensional geometry, wherein the blank (16) in the mould can be subjected for purposes of forming to pressure and temperature, and the blank (16) has perforations (18), at least in some regions. In accordance with the invention the lower mould (14) is formed at least partly with a permeable, in particular a gas permeable drainage layer (28). As a consequence of the gas permeable drainage layer (28) a blank (16) designed with perforations (18) in at least some regions can be formed directly, i.e. without further aids such as e.g. a means of sealing, etc and/or supplementary production operations, in the course of a superplastic forming process into a component, in particular into a suction component (46, 54) for an active aerodynamic surface of an aircraft, with a complex three-dimensional spatial shape and perforations (56) in at least some regions.In particular the device (10) enables production using a simple, cost-effective and reliable process that is suitable for large production runs of such components, spherically curved in at least some regions.
