<p>An inertial particle separator (IPS) for an inlet bell-mouth (28, 48) that couples an inlet air plenum (4) to a compressor (6) in a gas turbine engine (2), wherein the inertial particle separator removes air particles within reverse air flow passing through at least one bell-mouth aperture (30, 50) in the inlet bell-mouth (28, 48) into shroud bleed apertures (22) in a shroud (16) for the compressor (6), comprising: at least one baffle (32, 52) that protrudes from each bell-mouth aperture (30, 50) positioned to bend a reverse air flow stream (38, 58) through the bell-mouth aperture (30, 50) to a degree that forces particles out of the reverse air flow stream (38, 58) and into the inlet air plenum (4).</p> |
