Patent ID: 7264441

Claim:
A cycle HP compressor for a turbine engine, said compressor comprising: a plurality of rotor wheels and rectifiers arranged alternately, from upstream to downstream successively in a principal direction of air flow through the compressor, a first rotor wheel a first rectifier and a second rotor wheel, a separation slot set between the first rectifier and the second rotor wheel in order to supply the turbine engine with a secondary air flux, wherein the first rectifier is a double grid rectifier comprising a grid of vanes upstream as well as a grid of vanes downstream, wherein said grids of vanes upstream and downstream are associated respectively with variable setting systems upstream and downstream controlled in autonomous manner, wherein each vane of each of the upstream and downstream grids of the first rectifier is capable of being pivoted around an axis of rotation extending closely radially, and wherein for each vane of the upstream grid, the axis of rotation is located close to a trailing edge of said vane, and for each vane of the downstream grid, the axis of rotation is located close to a leading edge of said vane.
