A rotating assembly such as a counter-rotating propeller system or a turbofan includes a first rotating part rotatable relative to a second part, the first and second parts mounted on a common axis, a combustion engine arranged to rotate the first part, and an electric motor connected to drive the second part. In a first drive mode, the combustion engine rotates the first part in first direction relative to the axis while the electric motor drives the second part in a second, opposite direction relative to the axis and in a second drive mode, the combustion engine rotates the first part in the first direction and the electric motor does not drive the second part in the second, opposite direction.
