Abstract: An asymmetric inlet particle separator for a gas turbine engine includes an inlet having a first cross-sectional shape, and a duct downstream of the inlet. The duct includes a bend upstream from a splitter, a scavenge branch and an engine airflow branch. The splitter is outside of a line of sight from the inlet and the splitter separates the scavenge branch from the engine airflow branch. The asymmetric inlet particle separator includes an annulus downstream of the engine airflow branch configured to be coupled to the gas turbine engine. The annulus has a second cross-sectional shape, and the engine airflow branch transitions from the first cross-sectional shape to the second cross-sectional shape.

Abstract: A particle separator associated with a compressor section of a gas turbine engine includes a duct that defines a fluid flow path from a diffuser to a deswirl section. The duct includes a curved portion between an outlet of the diffuser and an inlet of the deswirl section. The curved portion is configured to have at least one low velocity region and a high velocity region. The particle separator includes at least one cluster of inlet passages defined at the at least one low velocity region. The particle separator includes a scavenge plenum coupled to the duct and in fluid communication with the at least one cluster of inlet passages. At least one outlet slot is defined through the duct downstream of the at least one cluster of inlet passages in the high velocity region and is in fluid communication with the scavenge plenum.

Abstract: An ejector driven scavenge system for a particle separator having a scavenge branch associated with a gas turbine engine includes at least one anti-icing circuit to receive an anti-icing fluid. The at least one anti-icing circuit is to be coupled to the particle separator. The ejector driven scavenge system includes at least one flow ejector bank to be coupled to the scavenge branch and fluidly coupled to the anti-icing fluid to direct the anti-icing fluid through the scavenge branch to drive air with entrained particles and water droplets from the particle separator.
