To prevent dust and other debris from entering the compressor (12) of a gas turbine engine (10) an inlet particle separator (30) is provided. Air contaminated with dust and debris is induced into a scavenge chamber (32). An exhaust vent (35) is provided from the scavenge chamber (32) through which the contaminated air is ejected to atmosphere. Flow dividers (40,42,44) are positioned in the scavenge chamber (32) to ensure that the flow into the chamber is uniform around the inlet passage.

An inlet particle separator comprising: a circumferentially extending scavenge chamber defined by one or more wall members and positioned radially outward of a duct, said scavenge chamber having an annular intake portion for receiving a flow of gas and particles from the duct; exhaust vent means for venting a flow of gas and particles from the scavenge chamber; and at least one flow divider positioned radially between the intake portion and the exhaust vent means, extending axially from one of said one or more wall members, and extending circumferentially at least part way round the scavenge chamber, said at least one flow divider being axially and circumferentially dimensioned and arranged in relation to said one wall member to define a plurality of flow paths of substantially even flow resistance which extend between the intake portion and the exhaust vent means.
