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.

Air inlet for a nacelle for an aircraft and its process for manufacturing

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

A pin for the production and positioning of parts made of composite material and glued together in an aircraft, the pin including an elongated body (), which is inserted in the holes purposely provided on parts of the aircraft or of the assembly jig. The pin also includes a head () that limits insertion of the pin in the holes, the body and the head being integrated in a single body made of a thermoplastic material. The process of production of the pin is a molding process.

A reference tool for assembly jigs for aircraft structures includes a constraint pin (), for being inserted into holes purposely provided on the assembly jig for aircraft structures and a reference support (), associated with the pin, for generating a gap between the parts of the aircraft structure, during assemblage, of a known and standardized amount.
