Propfans are expected to replace turbofans in commercial subsonic, air transportation systems for short and medium range. Thermodynamic cycle calculations are performed for a propfan and a turbofan propulsion systems for a 150 seat twin engine medium range transport aircraft, in order to obtain the difference in specific fuel consumption. Common definitions for the efficiencies of propeller and fan and common treatment of the thermodynamic cycles form the basis of the analysis.
