Summary:

This report proposes a new high efficiency "fuselage fan" concept of aircraft propulsion for subsonic airplanes also noted as "fusefan" (FF). The fusefan concept consists of one or two rings of swept blades rotating around the fuselage. This variable pitch fan has an important advantage in comparison with currently used turbofan engines: it dramatically increases the cross-sectional bypass area of the propulsion system by 3-5 times. As shown in the paper this propeller has an efficiency in cruise flight of 9-16% more than the current turbofan propulsion system. It also provides a large increase in static thrust (40-75%), which in turn decreases takeoff distance about 30-45%, and has a clean wing aerodynamically due to the absence of nacelles.An analysis of the benefits of the fuselage fan compared with the Advanced Turboprop Propeller (ATP) and propfan "Unducted Fan" (UDF) shows that for equal disk loading the "fuselage fan" has the following advantages:
