A gas turbine engine utilizes a main and at least one auxiliary particle separator for enhancing the separation of foreign particles from a stream of air entering the engine. The engine includes interior walls which collectively define an engine intake passageway and a compressor inlet passageway in flow communication with the intake passageway so as to provide a primary flowpath for air traveling through the engine to the engine compressor. The main and auxiliary particle separators each include a passageway associated with a corresponding interior wall of the engine. Each separator passageway has an inlet opening to one side of the main flowpath and directed generally upstream of the primary flowpath so as not to appreciably effect the pressure loss through the engine. Furthermore, each separator passageway includes a section adjacent its inlet which is arranged relative to the primary flow path extending thereacross so as to facilitate the acceptance of an amount of air flowing along and adjacent the corresponding wall by the separators and thereby facilitate the acceptance of foreign particles entrained within the amount of air.

A particle separator system for a gas turbine engine including interior walls defining an engine intake passageway including a throat for receiving engine intake air and an annular compressor inlet passageway in flow communication with the engine intake passageway, said system comprising: a main particle separator including an inlet passageway disposed downstream of said throat and in flow communication with the engine intake passageway for receiving a portion of foreign particles carried by the air entering the engine intake passageway, said inlet passageway of said main particle separator being provided by a pair of interior walls of the engine arranged so as to face one another, and an auxiliary particle separator associated with one interior wall of the engine including means defining an auxiliary passageway having an inlet downstream of said throat and in flow communication with said engine intake passageway for receiving an additional portion of foreign particles carried by the air entering the engine intake passageway so that the main and auxiliary particle separators provide the engine with an enhanced capacity for separating foreign particles from the engine intake air.
