Abstract: A casing for a turbomachine includes an internal hub, an external flange coaxial with the internal hub, arms extending radially from the internal hub to the external flange, each arm having a wall, two or more wire harnesses that connect a first electrical apparatus, which is arranged radially outside the external flange, and a second electrical apparatus, which is arranged radially inside the internal hub, a sheath extending within an arm at a distance from the wall of the arm, the sheath including an internal face defining an internal cavity that receives the two or more wire harnesses, and one or more shims mounted in the sheath and holding the wire harnesses at a distance from an internal face of the sheath and holding the wire harnesses at a distance from one another within the sheath.

Abstract: A device for feeding fuel to a combustion chamber in a turbomachine, the device comprising both an annular fuel feed rail extending around an outer casing of the combustion chamber, and a plurality of injectors fixed to the casing and opening out into the combustion chamber, the injectors being connected to the rail by fuel transport ducts and by support means that are deformable in bending, twisting, and pivoting, allowing the casing to expand thermally in a radial direction relative to the annular rail and providing rigid support for the annular rail.
