Rotor Control Equivalent Turbulence Input (RCETI) Models for Multi-Rotor Vehicles

Abstract

This research paper aims to investigate the applicability and scalability of the Rotor Control Equivalent Turbulence Input (RCETI) models to multi-rotor vehicles. The rotor inputs and outputs are used to develop an RCETI model for the heave axis. The study begins with the development of an RCETI model for variable-RPM rotors using the rotor RPM as input and the rotor hub-load coefficient as output. Next, the input is changed to incorporate rotor collective deflections, which could be used in multi-rotor systems. Further, the effect of altering rotor parameters on the RCETI model is studied and presented in the paper. Overall, this study offers insights into the potential of the generalization of RCETI models for use in multi-rotor systems.
