Abstract: A method of characterizing a part made of woven composite material, includes calculating autocorrelation values of a three-dimensional image in an observation window of the volume of the part for a plurality of spatial vectors used as the autocorrelation interval, and then detecting at least one local extremum in the autocorrelation value on a main orientation of the weaving in order to determine a mean in the observation window for the distance between neighboring parallel yarns.

Abstract: A thrust reverser of a propulsion system nacelle is provided. The thrust reverser extends circumferentially about a lengthwise-extending centerline. The thrust reverser includes a lengthwise-extending upper track beam, a lengthwise-extending lower track beam, an annular torque box extending circumferentially between the upper and lower track beams, and an annular cascade array extending circumferentially between the upper and lower track beams. The cascade array is circumferentially segmented into a plurality of cascade portions. At least one of the plurality of cascade portions is made at least substantially of a material that permits the at least one cascade portion to bear high loads during both a forward thrust operation of the thrust reverser and a thrust reversing operation of the thrust reverser.

Abstract: A composite external casing for a compressor of an axial-flow turbomachine, the casing comprising a generally circular wall having a matrix and a woven fibrous reinforcement. The latter is formed by a stack of fibrous plies having fibers woven according to a weft positioned in the axis of the circular wall, and a warp positioned around the circumference of the wall. The stack of plies comprising, depending on thickness, two external layers and one central layer. The layers include differences in the proportions between the weft fibers and the warp fibers. In the external layers the warp fibers make up the majority. In the central layer the weft fibers make up the majority. The stack exhibits interlayers inserted between the central layer and each external layer. The plies corresponding to the interlayers exhibit fibers woven at +45° and −45° in relation to the axis of rotation of the turbomachine.

Abstract: A fan assembly for gas assembly engine is disclosed. The fan assembly includes a rotor that is coupled to at least one fan blade. The fan assembly also includes a spinner that extends towards the rotor and the fan blades so that an edge of the spinner engages the fan blades. The edge of the spinner thereby serves as a grounding element for the fan blade. If the spinner is fabricated from a composite or a plastic material that is not sufficiently conductive for grounding purposes, the edge may be coated with a conductive material. Alternatively, the spinner may be fabricated from a metallic material, which would eliminate the need for a conductive coating on the edge that engages the fan blades.
