Preliminary Steps in Developing Rapid Aero Modeling Technology

Dynamic Modeling and Analysis of Tilt-Wing Electric Vertical Take-Off and Landing Vehicles

“…Even when computational efficient mid-fidelity simulations like DUST are deployed, this approach would disrupt the timeframe of the planned investigations on flight controls and FDIR. NASA proposed a promising framework called Rapid Aero Modeling (RAM) [16,46,47] that allows the derivation of high-fidelity data-driven aerodynamic models. It is deployed successfully for different eVTOL configurations, including tilt-wings [16,43,47], and is especially suited to derive models applicable for flight dynamics investigations.…”

It is deployed successfully for different eVTOL configurations, including tilt-wings [16,43,47], and is especially suited to derive models applicable for flight dynamics investigations. The key concept is to drastically reduce the number of experimental design points required to fit a data model while maintaining all relevant effects and relationships between dependent and independent variables.…”

“…A statistically distributed arrangement of design points in the high-dimensional input space is achieved by utilizing design of experiments (DoE) theory. While the authors in [16,47] conduct either wind-tunnel experiments or CFD simulations to gather data for a polynomial approximation, the choices of the method for the aerodynamic investigation and model generation are free in general. With regard to the expected medium fidelity and resource efficiency, the presented model will be extended by a data-driven approach inspired by the RAM methodology using DUST as a test facility in the future.…”
