Abstract: The invention relates to a hybrid cycle HP compressor (104) for a turbine engine, comprising in particular a first rotor wheel (16), a first rectifier (118) and a second rotor wheel (20), as well as a separation slot (22) fitted between the first rectifier and the second rotor wheel in order to supply the turbine engine with a secondary air flux. According to the invention, the first rectifier is a double grid rectifier comprising a grid of vanes upstream (30) as well as a grid of vanes downstream (34), these upstream and downstream vane grids being associated respectively with variable setting systems upstream and downstream (38,40) controlled in autonomous manner.

Abstract: A low of compressed air originating from a compressor stream (3) is drawn off through first orifices (13) towards ducts (5, 6) leading outside the casing, creating a flow division through adjacent cavities (11, 12) in the casing (1). These arrangements make it possible to carry a large air flow even if the cavity cross sections (11, 12) are small.

Abstract: A variable camber turbomachine vane is described in which at least one of a front part and a rear part is pivotable relative to the other about a pivot axis to vary the camber of the vane, and the facing end surfaces of the front and rear parts form a junction which provides for the continuity of the intrados and extrados faces of the vane as well as for sealing between these two faces. The pivot axis is offset on the intrados face side relative to the mean surface of the vane by a distance which is preferably at least one third of the thickness of the vane. Also, a cover is provided on the intrados side of the vane for masking the recess which is created in the intrados face at the junction when the camber of the vane is varied.
