Abstract: The present application relates to an axial turbomachine housing designed to channel a primary annular flow in the low-pressure compressor of the said turbomachine. The housing comprises a first shell and a second shell designed to be contiguous and coaxial. The first shell comprises a flange and a centering surface substantially cylindrical. The second shell comprises a flange and radial centering member designed to mate with the centering surface. The flange of the first shell includes cut-outs distributed along its circumference, and the centering member extends axially from the flange of the second shell through the said cut-outs to the centering surface where the two flanges are in contact.

Abstract: The subject application relates to blade root wedging lock in a circumferential groove in a rotor such as the drum of an axial turbomachine compressor. The body (32) of the lock includes a solid portion (38) designed to be housed in the groove and having two opposite bearing surfaces (40) and at least one circumferential wedging surface (42). The body (32) further includes an upper portion (36) in the shape of an elongated generally vertical chamber designed to be flush with the upper surfaces of the platforms of adjacent blades when the lock is correctly positioned. This chamber (36) is truncated (44) so as to reduce its length in a direction perpendicular to the circumference, corresponding to the axis of rotation of the rotor. The lock can thus be accommodated in a narrow groove without decreasing the diameter of the clamping screw passing through the hole (34). The subject application also relates to a rotor and a turbomachine equipped with the lock.

The means of immobilization comprise at least one tongue (38) with an end forming a support surface (40) in contact with a part of the blade (26) or of one of the blades (26) located radially directly above the corresponding cut-out.

Abstract: The present application relates to the compressor drum of an axial turbomachine. The drum includes a wall of revolution that forms a hollow body. The wall includes two annular retaining surfaces of the blades which mate with corresponding retaining surfaces of the said blades. These surfaces are generally directed away from one another to form a profile which diverges as its distance radially from the outer surface of the wall increases. The retaining surfaces of the drum may be formed on an outer annular body or on inclined annular flanges.
