Abstract: The invention proposes a method for manufacturing a grille for a cascade type thrust reverser, of a jet engine, said method including the following steps: a) manufacturing a first component comprising continuous or long fibres, pre-impregnated by a thermoplastic or thermosetting resin; b) manufacturing, subsequently or together with step a), a series of second components each including discontinuous fibres, pre-impregnated by a thermoplastic or thermosetting resin, step b) being carried out such that the second components are, on the one hand, arranged transversally with respect to a longitudinal direction of the first component on at least one side of the first component and, on the other hand, spaced from one another according to this longitudinal direction, so as to form a comb-shaped structure, wherein the second components are consolidated to the first component.

Abstract: A connecting rod includes two elastically flexible slats which are curved and arranged symmetrically relative to a longitudinal axis of the connecting rod. The slats have end zones running parallel to the axis, as well as transverse spacers placed between the slats and fasteners for securing the slats to each other and to the transverse spacers. The fasteners include adapters for adjusting the curve of the slats with a view to varying the axial length of the connecting rod.

Abstract: Composite-structure rotor for axial flow electrical machines comprising at least one stator and a rotor rigidly connected to a shaft to be rotated, in the shape of a disc and comprising a plurality of permanent magnets supported by a support made of a composite material rigidly connected to the shaft to be driven and constituted by a reinforced fibre matrix, The rotor comprises distributed attachment means for the radial elements and segments, which connect the elements in pairs, forming recesses, and which comprise at least one strap resulting from the winding of continuous unidirectional fibres passing between th Composite-structure rotor for axial flow electrical machines comprising at least one stator and a rotor rigidly connected to a shaft to be rotated, in the shape of a disc and comprising a plurality of permanent magnets supported by a support made of a composite material rigidly connected to the shaft to be driven and constituted by a reinforced fibre matrix. The rotor comprises distributed attachment means for the radial elements and segments, which connect the elements in pairs, forming recesses, and which comprise at least one strap resulting from the winding of continuous unidirectional fibres passing between the magnets, on the outside edge thereof, as well as on each of the attachment means, in order to form a collective retention of the magnets.
