Beschreibung
Zusammenfassung:	A method of cooling a gas turbine engine 250 is provided. The method comprises rotating, using an electric drive motor 500, rotational components 260 of a gas turbine engine 250, the rotational components 260 comprising an engine compressor 256, an engine turbine 258, and a rotor shaft 259 operably connecting the engine turbine 258 to the engine compressor 256. Each rotational component 260 is configured to rotate when any one of the rotational components 260 is rotated; wherein the electric drive motor 500 is operably connected to at least one of the rotational components 260 through an electro-pneumatic starter 120.
