The present invention comprises a method and apparatus for separating foreign objects from airflow channeled to an aircraft engine. An air intake including a foreign object separator is provided. The air intake includes an inlet duct having a bend for defining a pressure side, which inlet duct is effective for channeling airflow to the engine. A separator aperture is disposed in the pressure side of the inlet duct and a receptacle extends from the inlet duct and is in flow communication with the separator aperture. The receptacle includes a turning wall which is substantially arcuate in both a transverse plane and a longitudinal plane, and is substantially closed for preventing the flow of airflow therethrough while being effective for receiving and capturing foreign objects which enter the inlet duct and pass through the separator aperture.

For an aircraft engine, an air intake comprising: an inlet duct having a first bend in a longitudinal plane defining a pressure side and being effective for channeling airflow to said engine, said inlet duct having a separator aperture disposed in said pressure side thereof; and a receptacle extending from said inlet duct and being in flow communication with said separator aperture for receiving and capturing foreign objects which enter said inlet duct and pass through said separator aperture, said receptacle being substantially closed for preventing flow of said airflow therethrough and including a turning wall being substantially arcuate in a transverse plane and in said longitudinal plane to define a concave surface facing in an upstream direction, said transverse plane being disposed substantially perpendicularly to said longitudinal plane, for guiding foreign objects away from said separator aperture. A method for separating foreign objects from airflow channeled to an aircraft engine comprising the steps of: channeling substantially all incoming airflow to said engine through an unobstructed inlet duct having a bend in a longitudinal plane defining a pressure side; and providing a substantially closed receptacle including a turning wall being substantially arcuate in a transverse plane and in said longitudinal plane to define a concave surface facing in an upstream direction, said transverse plane being disposed substantially perpendicularly to said longitudinal plane, for guiding foreign objects away from said separator aperture, and being in flow communication with a separator aperture disposed in said pressure side of said inlet duct for receiving foreign objects of higher inertia than said airflow which are unable to turn with said airflow channeled through said inlet duct.
