Abstract:
1. A system for inertial particle separation, comprising: an outer first wall and an inner second wall coaxially and radially spaced apart from each other to define an annular main air flow path therebetween, the main air flow path extending from an ambient inlet to an outlet, the main air flow path extending radially outward and axially rearward from the ambient inlet and then curving radially inward and axially rearward to the outlet, said outer first wall defining an airfoil; means for selectively and controllably altering curvature of the first wall; a splitter member positioned between the first and second walls substantially at the radially inward curvature in the main air flow path, the splitter member extending axially rearward towards the outlet, the splitter member and the first wall defining a scavenge flow path and a scavenge cavity therebetween; and means for selectively and controllably altering curvature of said splitter member; whereby particulate matter entrained in air entering the ambient inlet is drawn into the scavenge flow path and scavenge cavity by inertia, thereby filtering the particulate matter from the main air flow path.
