Gust Response and Load Alleviation for Wingtip-Joined UAVs

Wingtip-joined modular High-Altitude Long-Endurance (HALE) Unmanned Aerial Vehicles (UAVs), or multi-body aircraft (MBA), promise enhanced endurance but face gust-induced instability challenges due to unique aeroelastic dynamics. This study characterizes MBA gust response and evaluates active control for gust load alleviation (GLA).

Wind Tunnel Testing of Gust Load Alleviation Performance of Flexible wing with Semi-Aeroelastic Hinge

High aspect ratio wings are particularly of interest to future aircraft design due to their superior aerodynamic performance. This paper describes an experimental campaign, as part of the U-HAWRAWD project, which was undertaken to investigate the gust ...
