The Application of Rotor Control Equivalent Turbulence Input (RCETI) Models to Multi-Rotor Vehicles

This research paper investigates the applicability and scalability of the Rotor Control Equivalent Turbulence Input models for multi-rotor vehicles. Initially, a Rotor Control Equivalent Turbulence Input model is developed for an isolated rotor using rotor RPM as the input and the rotor hub-load coefficient as the output. Subsequently, the model is applied to multi-rotor vehicle example to show that the effect of turbulence on vehicle response can be replicated using the Rotor Control Equivalent Turbulence Input models. This study further incorporates rotor collective deflections, which could be used in multi-rotor vehicles, to develop a collective input model. Additionally, the effect of altering rotor parameters on the Rotor Control Equivalent Turbulence Input model is studied and presented. The results demonstrate that the Rotor Control Equivalent Turbulence Input model effectively captures the turbulence-induced behaviors in multi-rotor vehicles, offering a generalizable and scalable framework for use to replicate the effect of turbulence in multi-rotor vehicles.
