An aeroengine is provided with a splitter apparatus disposed in a section of an inlet duct. The splitter apparatus can be actuated from a stowed position to a deployed position to allow splitter(s) to selectively move from out of the inlet flow to a position extending into the inlet duct to divide the inlet flow into multiple passages.


1. An aeroengine comprising an inlet duct for directing an air flow from an inlet opening to a compressor rotor, and an inlet splitter apparatus disposed within a section of the inlet duct and having at least one splitter plate pivotally mounted to a wall of the inlet duct about an axis substantially parallel to a direction of the air flow, the at least one splitter plate being pivotally moveable between a deployed position in which the at least one splitter plate extends from the wall of the inlet duct into the inlet duct to expose both sides of the pla...
