Abstract: Embodiments of the present invention provide an inertial filtration system for air-ingesting machines. The inertial filter 100 may comprise a reducer 133 downstream of a vortex generator. The reducer 133 decreases the area that the airstream flows through, which may increase the angular momentum and the centrifugal forces acting on the particles of the ingested airstream. This may increase the cleaning performance and a decrease in the pressure drop across the inertial filter 100. Generally, the inertial filter functions such that flow components of higher density are separated from the rest of the airstream. The higher density flow components are bled out of the inertial filter 100 via an outlet 135. The remaining flow components flow downstream to compressor section 535.

The system also includes a transition section, one or more flow diverters, one or more screens and/or a flow splitter to cause mixing of the different, temperature variant portions of the air flow and reduce the temperature variation distribution.
