  • Inlet particle separator
    Patent number: 4702071
    Abstract: 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.
