CFD Study of an Electric Ducted Fan Thrust System on Fibonacci Blade

Abstract Electric ducted fans can be used to generate the necessary force and moment for propulsion in many applications. It powered by an electric motor that rotates a multi-bladed propeller. EDF has different specifications for each size, in this study the focus is on knowing the thrust generated by the EDF using the computational fluid dynamics (CFD) method. Fibonacci number of blade is used 5, 8, and 13 blades with a diameter of 80 mm, with a duct housing size of 81 mm in diameter. The geometry model used refers to the 80 mm FMS brand EDF. The thrust value for each variation in the number of blades continues to increase as the rotational speed increases.
