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.
