Multi-function engine air inlet control

摘要

A multi-function air inlet control apparatus for an aircraft engine includes an air inlet frame housing a plurality of adjacent, spaced apart louvers attached by hinges at opposing ends to the air inlet frame. The hinges allow the louvers to pivot through a substantially 180 degree angle defined by a vertical plane of the air inlet frame. A linking device interconnects with each of louvers, whereby the louvers are moved in unison through the substantially 180 degree angle. An actuator communicates with the linking device for controlling the movement of the louvers in response to operating parameters of the aircraft engine. The multi-function air inlet control is a single device that fulfills the need for additional air during takeoff and other critical modes, and that will dump air overboard when the engine is throttling or is shut down.
