Abstract

A method is provided for operating an aircraft engine (10) in a fire-induced emergency state. The engine (10) is housed in a nacelle (41) defining a nacelle bypass duct (43) having a first outlet (45a) fluidly connected to an inlet (11) of the engine (10) and a second outlet (45b) fluidly connected to an environment external to the nacelle (41). An indication of a fire of the aircraft engine (10) is received. In response to receiving the indication, an emergency shutdown sequence of the engine (10) is initiated. In response to the initiating the emergency shutdown sequence, a volume of air entering the inlet (11) of the aircraft engine (10) is increased by restricting air flow through the second outlet (45b) of the nacelle bypass duct (43). The volume of air entering the inlet (11) is used to drive a rotor (14) of the engine (10). The rotor (14) is used to drive an oil pump (32) to circulate oil through a main oil conduit (35) of the engine (10).
