Unmanned aerial vehicles (UAVs) have become important equipment for overhead power grid inspection, yet general-purpose path planning methods are inefficient in large mountainous inspection areas and produce jagged paths that violate UAV turning limits. This paper presents an integrated pre-mission path planning framew...
This study examines the hovering and forward-flight stability of a heavy-lift coaxial unmanned helicopter with a suspended payload. A six-degree-of-freedom dynamics model is developed, coupling the rotor, fuselage, and a rigid-body sling via a universal joint, while neglecting rotor–payload aerodynamic interference for...
