Abstract

A bowed rotor prevention system (42) for a gas turbine engine (10) includes a core turning motor (44) operable to drive rotation of an engine core of the gas turbine engine (10). The bowed rotor prevention system also includes a full authority digital engine control (FADEC) (102) that controls operation of the gas turbine engine (10) in a full-power mode and controls operation of the core turning motor (44) to drive rotation of the engine core using a reduced power draw when the FADEC (102) is partially depowered in a low-power bowed rotor prevention mode.
