An unmanned rotor carried aerial vehicle comprises a propulsion unit (5) and a carrier (7) suspended from the propulsion unit. The propulsion unit (5) is connected to the carrier (7) via a cardan-like joint (9) for permitting limited tilting of the propulsion unit relative to the carrier in two orthogonal directions corresponding to the roll and pitch directions of the vehicle and for preventing relative movement between the propulsion unit and the carrier in the yaw direction of the vehicle. |
