    摘要： The invention relates to a casing for a turbine engine compressor, comprising: cavities (5) in the thickness of the casing, extending in parallel to one another from the inner face of the casing along a circumference thereof, said cavities not being in communication with one another. The cavities, which are elongate and extend along a main direction of orientation between two side walls, are closed upstream and downstream by upstream and downstream faces respectively, and an upstream border (7) and a downstream border (6) are formed at the intersections between same and the inner face of the casing (4). The casing is characterised in that the upstream border (7) of the cavities (5) takes the form of a wavy line comprising at least two alternate undulations over the length thereof between the aforementioned side walls.

    摘要： The invention relates to a turbine engine which comprises at least two consecutive annular rows of stationary vanes made up, for example, of the vanes of a synchronising ring (110) and by an annular row of casing arms (120) arranged downstream from the synchronising ring, each casing arm lying substantially in a radial plane passing between the trailing edges of two adjacent stationary vanes (112') of the synchronising ring, and the pitch (P1) between said two stationary vanes being greater than the pitch (P2) between the other stationary vanes (112) of the synchronising ring, such that the slipstreams (130) formed at the trailing edges of said two vanes pass respectively on either side of the corresponding casing arm.

    摘要： Turbomachine compressor comprising variable-pitch vanes comprising an aerofoil section connected by a mounting plate (17) of circular outline to a pivot (18) guided in rotation in an orifice in a casing (14), the mounting plate of the vane comprising at least one notch (60) for bleeding air from the compressor stream, this notch being intended to communicate with a hole (62) in the casing in order to remove the air bled off when the vanes are in a first position, and to be closed off by this casing when the vanes are in a second position, so that the flow rate of bled air depends on the pitch angle of the vanes.
