Abstract: Hybrid turbine engines and methods of operating the same are disclosed herein. The hybrid turbine engines include a first thrust-generating device that includes a turbine with a turbine rotary shaft and a clutch, which includes a clutch input, which is operatively coupled to the turbine rotary shaft, and a clutch output. The clutch defines an engaged state and a disengaged state. The hybrid turbine engines also include a rotary electric machine including a machine rotary shaft that is operatively coupled to the clutch output, a second thrust-generating device that is operatively coupled to the machine rotary shaft, and an electric power system. The rotary electric machine is configured to selectively receive an electric power output from the electric power system, such as to selectively produce additional thrust, and to selectively receive in an input torque from the machine rotary shaft, such as to selectively produce additional electric power.
