Sizing and Optimization of Fixed Pitch RPM-Controlled Rotors At Multiple Design Points For Passenger-Grade Multirotor Configurations

Abstract

This work summarizes the aspects of initial sizing of rpm-controlled rotors for multirotor eVTOL configurations. For the showcase, an isolated rotor with a simple recangular planform is sized with respect to peformance requirements in hover and in forward flight. The blade chord and twist is swept within a parameter range to find the minimum power required. Results show the correlation between the design parameters and the rotor performance for various disc and blade loadings, given constant rotor thrust and blade number.
