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

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.

A method for making hollow stiffening elements with co-curing technique on a structure made of composite materialincludes the use of at least a lamination and polymerization spindleupon which is positioned at least a rolled section. The rolled sectionforms at least a hollow structurewhere there is the spindle, including the following operational phases: coating the spindlewith at least a first anti-adherent layer; coating the spindlewith at least a second heat-shrinking layer; heating the coated spindle; positioning the spindleon the surface of the structure; laminating the surfacethrough at least a rolled section; heating the structurewith at least a positioned rolled section; extracting the spindlefrom the hollow structure
