Abstract
It is well known that electric engines with a large external helice presents an higher propulsive efficiency if compared to electric turbofans. This paper defines the general guidelines for enhancing the efficiency of an electric turbofan by CFD symulations. A mathematical model to design the intake nozzle has been presented in order to allign the performance of the two systems. The analysis has been realized by basic fluid dynamic principles only, using traditional actuator disk propeller model for the verification of the results.
