Aero-Propulsive Modeling for eVTOL Aircraft Using Wind Tunnel Testing with Multisine Inputs

A Novel Aerodynamic Modeling Method Based on Data for Tiltrotor evtol

“…Therefore, wind tunnel test data under different tilt angle conditions were selected as the validation set to verify the network's predictive effect. The validation results compare wind tunnel data, results from the mathematical model established in the literature [9], and predictions from neural network models. The purpose is to illustrate the difference between data-driven modeling methods and models established using traditional physical formulas.…”

“…These variations in rotor-induced velocities, as well as the effects of rotor downwash and wake, make aerodynamic modeling extremely challenging. Some aerodynamic propulsion modeling methods for lift + cruise evtol aircraft are proposed in references [7][8][9][10]. System identification techniques and computational fluid dynamics (CFD) simulations are used to develop flight dynamic models and validate the predictive capabilities of aerodynamic propulsion models.…”
