The objective of the paper is to study the F-Helix eVTOL concept. This concept modifies the SH-4 Silvercraft light helicopter to use electric propulsion and a tip driven rotor. It is intended to compete with rotorcraft in the light-weight class and address future urban air mobility needs. The elimination of shaft driven propulsion is intended to reduce weight and drag in order to accommodate the added weight of batteries for energy storage. Once the configuration of the rotorcraft is established, the design is optimized to produce the least power required while still meeting the structural and physical constraints of its components. Next, a simulation model is developed to assess the rotorcraft performance in hover and forward flight. The payload/range performance is then evaluated for a typical aerial urban transportation mission. Finally, the performance of the eVTOL configuration is compared to the SH-4.
