		abstract={Electric ducted fan (EDF) is a type of electrical propulsion system 
configuration with the motor power source coming from the battery and consists of 
a fan surrounded by a duct casing to increase the amount of air compression, to 
produce a higher thrust compared to conventional rotor of the same diameter. One 
of the most important components in an EDF system is a fan. The selection of fan 
design configurations on the EDF will have a major effect on the thrust generated. 
To fulfil their propulsion needs, one usually buys a propulsion system from a 
manufacturer that is not satisfy the DRO (design requirements and objectives) of 
the flying vehicles. It is necessary to have a rotor (fan) from EDF that is in accordance 
with DRO, so a fan design is needed on EDF. Therefore, research was carried out on the 
design of an EDF fan with a diameter of 90 mm.
The designed fan has a diameter of 90 mm with 4 blades, the size of the hub /
tip is 0,5. The results of the analysis showed that there was a significant difference
in the thrust value between theoretical calculations and computational fluid
dynamics(CFD) simulation. At a design rotation of 38850 rpm, from the momentum
theory of the blade element, a thrust of 36 N was obtained, while numerically
simulation using ANSYS software obtained a thrust of 30,476 N. The discrepancy 
was due to improrer shape of the spinner, tailcone, bellmouth, stator and fan?s duct.}
