Abstract

The inlet (2) has a duct (3) extending along suction direction (DO). A rectifier (10) comprises a hollow honeycomb structure (11) arranged in an inlet section (6) of the duct. The structure includes a set of hollow tubes (20) extending parallel to the suction direction from a downstream section toward an upstream section. The structure is unsealed for slowing down a bird (4) tending to cross the duct by crushing a partition common to adjacent hollow tubes and to rectify air flow, where the air flow crosses the inlet section through the tubes to be rectified.
