The future of aviation depends on energy transition and environmental mitigation. Hydrogen-powered aircraft offer the potential to eliminate carbon emissions during flight, but their integration poses major challenges in storage, thermal management, and pollutant emissions. This study explores the conceptual design...

This work evaluates Deep Gaussian Processes (DGPs) as probabilistic surrogate models for predicting thrust and torque of small Unmanned Aerial Vehicle (UAV) propellers. Unlike deterministic neural-network models, DGPs provide predictive uncertainty estimates in addition to mean predictions. Compared with standard Gauss...

Modern high aspect ratio configurations deliver aerodynamic efficiency at the cost of significant geometric nonlinearities and highly coupled fluid-structure interactions. Sub-scale testing remains indispensable for validating the resulting aeroelastic phenomena, yet aerodynamic similarity is fundamentally challenged b...
