Abstract: Example embodiments relate to methods for assembling optical modules of a luminaire and optical assembly. One example method includes providing a frame with at least one opening. The method also includes providing a plurality of optical modules to the frame, each optical module of the plurality of optical modules being provided to an opening of the at least one opening. Additionally, the method includes providing a support means to each of the plurality of optical modules and/or to each of the at least one opening. Further, the method includes assembling the plurality of optical modules to the frame by plastically reshaping a material portion in contact with the frame and the optical module. When the optical module is assembled to the frame, a first bottom surface of the optical module is substantially at a same level as a second bottom surface of the frame.

Abstract: A compressor casing for a turbine engine, the casing comprising: a housing comprising a radially inner e surface; an upstream ferrule; and a downstream ferrule; each of the ferrules having a respective inner surface capable of defining an air stream, and each of the ferrules having an outer surface facing the inner surface of the housing, the ferrules being attached to the cantilevered housing and being axially arranged so as to be separated by an axial clearance. Additionally, a turbine engine comprising such a casing and a stage of variable-setting vanes.

Abstract: A method for assembling optical modules comprising the steps of: providing a frame with at least one opening; providing optical modules to the frame, each of the optical modules being provided to one opening; welding optical modules to the frame; providing a support means to each optical module and/or to each opening, said support means for supporting the optical module at least partially within the opening; assembling the optical modules to the frame by plastically reshaping a material portion in contact with the frame and the optical module, the plastic reshaping occurring under an application of heat and/or pressure; wherein, when the optical module is assembled to the frame, a first bottom surface of the optical module is substantially at same level as second bottom surface of the frame, said first bottom surfaces and second bottom surface adapted for being arranged on a support carrying light sources.

Abstract: An assembly for the compressor stator of a turbomachine. The assembly comprises: a shroud, in various instances an inner shroud, that is axially divided into two parts; a pocket formed in the shroud; a bearing located in the pocket; and an orientable vane pivotably mounted in the bearing about a pivot axis. The shroud comprises an axial interface separating the parts that is axially offset from the pivot axis of the orientable vane. The invention also provides a process for assembling the assembly.

Abstract: An assembly for a turbine engine includes an upstream section and a downstream section, each having an annular row of semi-cylindrical radial recesses and a plurality of flanges positioned between two circumferentially adjacent recesses for holding the two sections together. The recesses form a cylindrical opening when the two sections are assembled. The openings receive pivot sections of variable stator vanes.

Abstract: The invention concerns an assembly for the stator of a compressor of an axial-flow turbine engine, such as a low-pressure compressor of the turbojet engine also known as a booster. The assembly comprises: a first annular array of first vanes of the stator extending radially in the axial flow; and a second annular row of second vanes of the stator, with controlled orientation, also known as variable-pitch vanes or VSV. In addition, the assembly comprises an external monobloc shroud on which the first vanes and the second vanes are mounted in a pivoting manner.
