<p>A gas turbine engine arrangement (10) comprises a core engine (12), a power turbine (32) and a propulsor (14). The core engine (12) comprises at least one compressor (16,18) and at least one turbine (22,24) arranged to drive the at least one compressor (16,18) and the core engine (12) is arranged in a casing (30). The power turbine (32) is positioned downstream of the at least one turbine (22,24) and the power turbine (32) is arranged to drive the propulsor (14). An electrical machine (36) is arranged upstream of the at least one compressor (16,18). The electrical machine (36) comprises a stator (38) and a rotor (40) and the electrical machine (36) comprises a motor/generator. A first clutch (42) selectively connects the rotor (40) of the electrical machine (36) to the power turbine (32) and a second clutch (44) selectively connects the rotor (40) of the electrical machine (36) to the at least one compressor (16,18) of the core engine (12).</p> |
