Asymmetric inlet particle separator system

Abstract:

An asymmetric inlet particle separator system (AIPS) includes a bifurcated duct system that defines an inlet for receiving inlet air. The bifurcated duct system includes a core air channel and a scavenge air channel and is configured to separate the inlet air into core air and scavenge air. The scavenge air channel includes a first plurality of turning vanes configured to turn the scavenge air in a first direction and a second plurality of turning vanes configured to turn the scavenge air in a second direction. The AIPS also includes an asymmetric scroll coupled to the scavenge air channel. The asymmetric scroll includes a first arm having a first arm length and a second arm having a second arm length that is different than the first arm length.
