A rotating assembly such as a counter-rotating propeller system or a turbofan, comprising a first rotating part (20) rotatable relative to a second part (21), the first and second parts mounted on a common axis (22), a combustion engine (23) arranged to rotate the first part, and an electric motor (24) connected to drive the second part, whereby 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.
