A radial inflow particle separator includes a pair of axially and radially spaced curvilinear walls cooperatively defining a circumferential flow path leading radially inwardly and axially to an engine. Preferably, the particle separator is employed with a turbine engine which is operated at times in an environment laden with dust and particulate matter. Such an environment is typically encountered by a turbine engine of a helicopter, or off-road vehicle. The particle separator provides dust and particulate control features including aero-inertial, particle trajectory, particle boundary-rebound, and scavenge flow tailoring to achieve a dust and particulate separation efficiency as good as or better than the best conventional axial-flow particle separators. This particle separation effectiveness is achieved in a radial inflow particle separator which is smaller and lighter in weight than axial flow devices, and which packages advantageously with the essential structures of a turbine engine.

A radial inflow particle separator comprising an axially and radially spaced apart pair of walls cooperatively defining therebetween an annular air flow path leading radially inwardly from an ambient inlet and then turning axially to an outlet, an annular radially and axially extending splitter member interposing axially and radially between said pair of walls substantially at the turning of said flow path and cooperating with one of said pair of walls to separate from said flow path a scavenge flow path having an annular inlet confronting said ambient inlet, said pair of walls each including a respective annular axially extending prominence spaced radially from the prominence of the other of said pair of walls, and said axial prominences cooperating to bound a line of sight radially into said particle separator, said line of sight at its radially inner limit being entirely within said scavenge flow path inlet.
