Nitpick: a turbine extracts power from a moving fluid. A fan (or impeller) imparts power to a fluid. A traditional jet engine contains both components, which is why they are sometimes referred to as "gas turbines". In an electric jet, there are no turbines and the proper term is "ducted fan" or "electric ducted fan (EDF)".
