ABSTRACT:
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.
