This study explores the unique challenges posed by High Altitude Long Endurance (HALE) aircraft, focusing on their extreme flexibility. It investigates the significant deformations
experienced by the lightweight and highly flexible wings during flight. To address issues like differential drag during takeoff and landing, an innovative solution – a Multi-Body Aircraft (MBA) design with wingtip docking capability – is introduced. However, multiple wingtip dockings introduce inevitable geometric nonlinearities, significantly affecting the aircraft’s aeroelastic design. Aeroservoelastic analysis of unmanned multi-body aircraft considering geometric nonlinearities is urgently needed. The research develops a nonlinear finite element model and proposes control laws combining Deep Q Network and LQR control to effectively suppress gust responses, enhancing overall flight stability. This exploration provides valuable insights into the dynamics of flexible unmanned multi-body aircraft.
