Podłużna stateczność dynamiczna śmigłowca z podwieszonym ładunkiem w zawisie

Physical model and equations of motion of a hovering single-rotor helicopter with a hanging load are given. Three degrees of freedom are considered: pitching of the helicopter as well as horizontal translations of the helicopter and the load. Stability is analyzed by the method of small perturbations. As a numerical example, the modes of motion of the helicopter-load system as well as the influence of the load mass, the link length and the suspension offset of the link are investigated for the typical light helicopter.
