Thermodynamic cycle calculations were done for a propfan and turbofan propulsion system for a twin engine, medium range transportation aircraft to show the differences in specific fuel consumption. Common definitions for the efficiencies of propeller and fan and common handling in one cycle program were used. Results show 15% to 20% specific fuel consumption improvement, which depends on the mastering of interference between propeller stream and bearing surface.
