An improved deflector type of device for preventing suction of foreign matter into an air intake port of a gas turbine engine for an aircraft. The deflector is movable and by displacing said movable part to a desired position an intake air flow passageway of the engine can be varied. Thus, suction of foreign matter into a gas turbine engine during a flight under a freezing weather condition can be prevented without degrading air intake efficiency during a flight under a non-freezing environmental condition.
A device for being mounted in front of an aircraft engine air intake to prevent foreign matter from being sucked into the engine, said device comprising; a first, fixed portion for extending as a deflector before the air intake and having a cutaway, open area for exposing at least part of the air intake to air flow directly ahead of the air intake; a second, movable portion having an inlet region communicating therethrough to an outlet region thereof, and a deflector region extending between the inlet region and outlet region; and pivot means mounting th...
