Flight-Log-Based Assessment and Center-of-Gravity-Oriented Redesign of a Large Flying-Wing VTOL UAV

This study evaluates the VTOL behaviour of a 4.18 m-span, 15.5 kg flying-wing UAV and proposes a simplified propulsion-layout redesign. Three flights of the original tri-rotor configuration were analysed using attitude, motor and servo PWM, altitude, and vibration data. Roll and pitch tracking errors averaged 0.54° and...

Static Ground Validation of an AI-Assisted Acoustic Target Detection and Azimuth Estimation Framework on a Flying-Wing VTOL UAV

Autonomous acoustic sensing systems are increasingly investigated for unmanned aerial vehicle (UAV)-based surveillance and environmental monitoring applications due to their passive operation and relatively low computational requirements. However, the integration of acoustic classification and direction-of-arrival esti...

Effect of Inclined Cavities on Vortex Evolution in a Vertical-Axis Wind Turbine

This study investigates the influence of inclined surface cavities on vortex evolution and aerodynamic performance in a three-bladed H-Darrieus vertical-axis wind turbine. A baseline NACA0012 rotor and four cavity-modified configurations were evaluated using two-dimensional transient computational fluid dynamics with a...
