Electrically propelled airship having a rigid structure and power-generating nacelle with which said airship is provided

An airship, comprising:

• a main body having a rigid structure surrounding a plurality of containers of a lighter-than-air gas, a plurality of propeller units mechanically connected to the rigid structure and each comprising one or more electric motors for driving a pusher thrust propeller, and power-generating units for powering the one or more electric motors;
• and
• two nacelles symmetrically arranged on either side of the main body, each of the two nacelles configured to receive one or more of the power-generating units, each of the two nacelles comprising a mechanical structure connected to the rigid structure of the main body by:
• a joint interface of a specific point of a lower part of the nacelle mechanical structure relative to the rigid structure,
• fail safe interface between a point of an upper part of the mechanical structure of the nacelle and the rigid structure of the main body of the airship, the fail safe interface configured to maintain a secondary standby mechanical connection beyond a predetermined upper tensile limit, and
• at least one rod or traction stay cable between a first point of attachment on the rigid structure of the main body of the airship and a second point of attachment on the mechanical structure of the nacelle.
