An airfoil of an aerodynamic surface including: a control surface having an upper surface and a lower surface, and an actuator configured to elevate or lower the control surface, wherein at least a portion of one of the upper surface and the lower surface of the control surface is auxetic with a negative Poisson ratio, and the other of the upper surface and the lower surface of the control surface includes a material with a higher Poisson ratio.

Tooling for manufacturing multi-spar torsion boxes with different web heights, the tooling includes a mandrel module having a hollow beam geometry which comprises a first base and a second base opposite to the first base, and two walls extending between said first base and said second base, and at least one spacer module configured for coupling with the mandrel module, wherein the web height of a multi-spar torsion box is defined by the coupling between the mandrel module and at least one spacer module. A method for manufacturing multi-spar torsion boxes with different web heights.

A computer assisted method for manufacturing a foldable paraboloid antenna includes election of a two-dimensional radial Origami pattern with triangular cells and election of a paraboloid surface. The Origami pattern is projected from the paraboloid surface focus onto the paraboloid surface to print the Origami pattern on the paraboloid surface, obtaining triangles with curved sides. A pattern with triangles with straight sides on the paraboloid surface is obtained by joining vertices of the projected curved-sided triangles. The method includes scaling and calculating centroids of the triangles, to reduce each triangle referenced on the corresponding centroid and to determine spacing, obtaining a mesh with segments and triangular cells delimited by the segments. The triangular cells have triangles of reflective rigid material. The mesh is flexible, so each segment width is at least the sum of the thicknesses of two adjacent rigid triangles, and periphery cells have a rounded outer edge.

A method for manufacturing a part layer-upon-layer using Additive Manufacturing technology, the method including: printing the part together with an elastomeric enclosure shaped thereto leaving a gap free of material therebetween, the elastomeric enclosure including at least one opening; heating the ensemble of the printed part and elastomeric enclosure or keeping an operating printing temperature; applying vacuum by the at least one opening of the elastomeric enclosure so that the elastomeric enclosure deflates thus exerting pressure to the printed part; and maintaining the printed part under vacuum and heat during a predefined time.
