In this place, the following terms or expressions are used with the meaning indicated:
Balloon | Rigid or non-rigid free-flying (no directional control) lighter than air aircraft |
Blimp | Non-rigid flight controlled lighter than air aircraft |
Zeppelin | Rigid flight controlled lighter than air aircraft |
Hybrid airship | Aircraft where lift is produced by both lighter than air compartments and aerodynamic surfaces (wings) |
This place covers:
General lighter-than-air concepts; e.g. hybrid airships.

This place covers:
Non-rigid airships in which the contours of the outer covering are maintained by ties or cords connecting opposite inner surfaces of the outer covering

Framework construction for rigid airships |
The ties or cords maintain the shape of the inflated airship (note that B64B 1/02 is related to non-rigid airships), i.e. they are essentially in tension to maintain the shape. If the ties/cords connect unsubstantial frame members and are in tension due to the pressure in the inflated airship body, they can also connect frames related to the outer covering.
This place covers:
Means for attaching the outer covering to the inner structure.
This place covers:
Arrangement of propellers in relation to the hull
Propellers in general are covered by B64C 11/00
This place covers:
Conventional balloons of generally spherical shape where the outer cover serves as gas bag, e.g. traditional hot air balloons.
