摘要： An element (26) for sound absorption is intended for being mounted on components of aircrafts, such as engine nacelles. The element includes a face-sheet (28), which is, at least in a region thereof, acoustically permeable, a substantially sound-reflective back-sheet (30) and a honeycomb layer (32), “sandwiched” between the face-sheet (28) and the back-sheet (30) and defining a mesh structure which has hollow cells (34, 34′) laterally neighboring one another. The cells (34, 34′) are adapted to make the sound waves that enter through the face-sheet (28) and are reflected by the back-sheet (30) resonate inside their side walls. The element (26) has a passage (36) that connects together a group of the cells (34, 34′), thereby causing the cells to acoustically cooperate with one another.

摘要： A vacuum bag (18) is placed around the inner forming surface (IML) of an inner mandrel with radially retractable sectors (11a, 11b) having parallel longitudinal slots (17) with composite stringers (30) in the slots (17). An inner support (31) in each stringer is covered by an impermeable tubular bag (32). A composite skin (37) is laminated around the stringers (30), the coated supports (31, 32) and the inner forming surface (IML). An outer curing tool (50, 51) closes around the skin (37) defining an fuselage barrel outer forming surface (OML), leaving an annular gap (G) between the skin outer surface (37) and the outer forming surface (OML). Vacuum is applied between the vacuum bag (18) and the outer tool (50, 51), enlarges the uncured barrel diameter, releasing the barrel from the inner mandrel (10) and bringing the skin outer surface (37) into contact with the outer tool inner surface (IML).

摘要： A constraint system of sectors of a device for producing an airplane fuselage in which a lamination mandrel is adapted to receive and support a band of impregnated synthetic material. The lamination mandrel comprises a plurality of sectors angularly spaced about the axis and mobile between: an expanded lamination position and a contracted disassembling position. A constraint system is provided between each sector and the sectors adjacent thereto which guarantees a predetermined arrangement of the first sector with respect to the second sector adjacent thereto, preventing any translation along two directions which lie in an adjustment plane perpendicular to an axis RD which extends radially from the symmetry axis to the external surface.

摘要： A nozzle removes by suction dust and chips from a drilling machine in an industrial plant. The nozzle has a first tubular portion for connection to a suction tube communicating with an opposite second tubular portion with an intake opening. An outer flange extends transversely from an intermediate position between the first and second tubular portions. The intake opening is directed in a lateral direction, parallel to the transverse direction of the flange. A magnetic element is incorporated in the flange. The nozzle can be applied to a drilling template having cylindrical through-openings in which respective bushings made of ferromagnetic material are fixed. When the second tubular portion is inserted through a cylindrical bushing, the magnetic element acts on the bushing, opposing axial and rotational movements of the nozzle.

摘要： A matched mold curing apparatus defining a molding cavity has two sets of layers of curable, fiber-reinforced, thermosetting composite material laminated on a lower forming tool and upper forming tool. Closed-cell foam core segments are provided and placed adjacent to each other on the layers. The core segments are oversized with respect to the nominal size determined by the molding cavity in the closed condition, minus the thickness of the layers of composite material. A controlled temperature is applied firstly to allow plastic deformation of the core segments, but without closing completely the matched mold. The temperature and pressure are then applied to cause complete closure of the matched mold and curing of the laminated layers.

摘要： Methods of making single piece multi-spar boxes made of composite material for aircraft are provided. Such methods include providing outer spars of the boxes which are made with a C-shaped cross-section such that the spars, during curing, are molded on the inside onto rigid, outer, lateral forming tools. As a result it is possible to obtain very precise outer profiles and positions of the spars.

摘要： A tool for forming a C-section beam made of carbon fiber includes a straight elongated mandrel with a rectangular or trapezoidal cross-section. The mandrel has three consecutive outer faces, with a planar face configured to form a surface of the web of the C-section beam, and two opposing lateral faces, configured to form two respective surfaces of the flanges of the C-section beam. The mandrel has a distributed perforation on at least one of the three outer faces and an inlet/outlet connection to connect the mandrel to an external source of vacuum and/or compressed air. Passages are formed inside the mandrel to establish a fluid communication between the distributed perforation and the inlet/outlet connection. Through the distributed perforation, a vacuum is applied to the interface between the mandrel and the C-section beam to retain the C-section beam on the mandrel while lifted and turned by 180° for coupling to a similar C-section beam to assemble an H-beam. Applying compressed air through the perforation facilitates the removal of the C-section beam from the mandrel at the end of the compaction step.
