Envelope with variable shape and volume

Envelope with variable shape and volume

This innovation allows the envelope’s volume and shape to be altered in flight or on the ground to adapt to the flying conditions. This innovation creates the following advantages:

– Versatility, ability to switch between hovering and flying at cruising speed

– Simplified implementation

One shape is suited to hovering, whereas the other is suited to other flight phases (cruising, landing, approach, etc.).

Few airport infrastructures are able to accommodate aircraft that are over 12 meters tall.

This system offers the possibility of reducing the height of the airship’s envelope, and therefore the hangar height, by 30 per cent.
