MULTI-CHANNEL PARTICLE SEPARATOR

摘要

A multi-channel particle separator (152) includes a plurality of vanes (202). Each vane is spaced apart from at least one other adjacent vane to define a flow channel (204), and includes a leading edge (206), a trailing edge (208), a first side wall (212), a second sidewall (214), and a splitter (216). The first side wall extends between the leading edge and the trailing edge. The second side wall is spaced apart from the first side wall and extends from the leading edge toward the trailing edge. The splitter is rotationally coupled to the trailing edge and extend toward the leading edge. The splitter is spaced apart from the first side wall to define a scavenge volume (218) and is rotatable between an extended position and a retracted position. In the extended position, the splitter (216) is spaced apart from the second side wall (214) to place the scavenge volume (218) in fluid communication with the flow channel (204). In the retracted position, the splitter (216) engages the second side wall (214) to fluidly isolate the scavenge volume (218) from the flow channel (204). The splitter is moved between the extended and retracted position via an actuator (154), which is coupled to each splitter (216). The vanes may also be coupled to a ringshaped structure.
