Abstract

A turbine engine (20) is provided that includes compressor, combustor, and turbine sections (30, 32, 34), an outer casing (52), an inner diffuser case (60), a particle separator (58), and a mechanism (96) for producing an electrostatically charged surface. A diffuser outer diameter (OD) flow path (62) is disposed radially between the outer casing (52) and the combustor (35). A diffuser inner diameter (ID) flow path (64) is disposed radially between the combustor (35) and the inner diffuser case (60). The particle separator (58) is disposed in the diffuser OD and/or ID flow paths (62, 64). The particle separator (58) includes a housing (98) that extends between forward and aft ends (120). The particle separator (58) includes helical dividers (100), a collection pocket (110), an inlet aperture (106), and a plurality of exit apertures (108). Air flow enters the particle separator interior cavity (118) through the inlet aperture (106) and enters a first passage. The collection pocket (110) is in fluid communication with the first passage and is disposed to receive particulate matter entrained within the air flow.
