Analysis and Optimization of Hanging Stability of Heavy-Duty Coaxial Unmanned Helicopter

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...
