[Object] To provide a gas turbine engine which is simple in structure but can effectively remove foreign matters from the combustion air. [Means] The intake passage 21 includes an inlet portion 29 , a curved portion 30 and a reduced diameter portion 31 . The bypass duct 24 is curved away from the central axial line CL in a region corresponding to the curved portion 30 and reduced diameter portion 31 of the intake passage 29 . Between the intake passage 29 and bypass duct 24 is defined an annular space 32 . In the reduced diameter portion 31 , the outer liner 20 is formed with a large number of foreign matter introduction openings 33 in a circumferential arrangement for communication between the intake passage 21 and annular space 32 . The inner casing 4 is formed with a plurality of foreign matter ejection holes 34 in a circumferential arrangement in a part thereof that curves outward for communication between the annular space 32 and bypass duct 24.
