ELECTROSTATIC CHARGE CONTROL INLET PARTICLE SEPARATOR SYSTEM

摘要

An inlet particle separator system for an engine includes an inner flowpath section, an outer flowpath section, a splitter, a first electrostatic discharge device, and a second electrostatic discharge device. The outer flowpath section surrounds at least a portion of the inner flowpath section and is spaced apart therefrom to define a passageway having an air inlet. The splitter is disposed downstream of the air inlet and extends into the passageway to divide the passageway into a scavenge flow path and an engine flow path. The first electrostatic charge device is disposed between the air inlet and the splitter and is electrostatically charged to a first polarity. The second electrostatic charge device is disposed downstream of the first electrostatic charge device and is electrostatically charged to a second polarity that is opposite to the first polarity.

1. An inlet particle separator system for an engine, comprising:
an inner flowpath section; an outer flowpath section surrounding at least a portion of the inner flowpath section and spaced apart therefrom to define a passageway, the passageway having an air inlet; a splitter disposed downstream of the air inlet and extending into the passageway to divide the passageway into a scavenge flow path and an engine flow path; a first electrostatic charge device disposed between the air inlet and the splitter, the first electrostatic charge device electrostatically charged to a first polarity to thereby impart an electrostatic charge of a first polarity to at least a portion of particulate entering the air inlet; and a second electrostatic charge device disposed downstream of the first electrostatic charge device and electrostatically charged to a second polarity that is opposite to the first polarity, whereby particulate charged to the first polarity is attracted toward the second polarity.
