Abstract
This turbine engine compressor comprises a separating nose extended by inner and outer annular walls defining in cooperation an annular volume (V) of separation of a primary flow (F) and a secondary flow (F). This volume (V) comprises a plurality of annular segments in the form of cells separated in pairs by blades of a first fan, these blades passing through both the primary flow (F) and the secondary flow (F). These cells are fixed to an upstream annular collar and a downstream annular collar driven rotationally by the aforementioned blades.
