Abstract: An air inlet (3) for a nacelle (2) for an aircraft (1) includes at least one acoustic panel (5), adapted to lower noise generated by the engine (21) to which the air inlet (3) is connected. At least one lip (6) defines the profile upon which an airflow flowing into the air inlet (3) acts. If necessary, at least one engine ring (4) is adapted to allow the air inlet (3) to be connected to an engine (21) of the nacelle (2). If necessary, at least one outer barrel (7) is adapted to define the outer shape of the air inlet (3) upon which an airflow acts. The air inlet (3) is manufactured as one single piece, made of a composite material.

Abstract: A covering element is adapted to protect a paint-sensitive area wherein at least one opening is defined. The element includes a central stem having a distal portion intended to go through the opening, and a cap peripherally extending from a proximal portion of the central stem, for covering the area.

Abstract: A method includes providing an aircraft component including a substrate made of composite material and a polymeric matrix; and applying a protective coating made of metallic material to the substrate. The protective coating is applied to the polymeric matrix by an electrolytic deposition process.

Abstract: A method is for manufacturing a plurality of hollow reinforcement structures for panels (P) or aerostructures. The method includes the following consecutive steps: a) positioning at least one mandrel on the surface of a panel (P) in correspondence to each hollow structure to be manufactured; b) laminating at least one composite material layer on top of each mandrel; c) polymerizing the panel (P) on which the at least one composite material layer is applied; d) removing the at least one mandrel from the hollow structures. At least two of the hollow reinforcement structures intersect one another. A single polymerization step b) is provided for all the hollow reinforcement structures.

Abstract: A method for making hollow stiffening elements with co-curing technique on a structure made of composite material 1 includes the use of at least a lamination and polymerization spindle 2 upon which is positioned at least a rolled section 3. The rolled section 3 forms at least a hollow structure 11 where there is the spindle 2, including the following operational phases: coating the spindle 2 with at least a first anti-adherent layer 41; coating the spindle 2 with at least a second heat-shrinking layer 42; heating the coated spindle 2; positioning the spindle 2 on the surface of the structure 1; laminating the surface 1 through at least a rolled section 3; heating the structure 1 with at least a positioned rolled section 3; extracting the spindle 2 from the hollow structure 11.
