A lighter-than-air airship has self sealing capacity and comprises landing gear having a ball and socket design which is, preferably, filled with lighter-than-air gas and has a socket that may swivel in order to cover the ball during flight to give an aerodynamic shape. A hull of the airship has a wing profile which provides a smaller radar footprint. The airship is provided with a pressure equalisation system for active control of roll and yaw rate between damaged and undamaged sections. The pressure equalisation system comprises a gas distribution valve system which also affords pressure distribution/equalisation with a front section of the airship in order to regain stability and gain maximum benefit from a counter acting flap system. A passenger/cargo compartment that may be raised or lowered is also provided and the airship may be anchored by landing anchors shot into the ground and used to wind the airship down without using ballast. The airship has flat planes on which may be mounted film screens and/or solar panels etc. In another invention a propeller has an outer blade rim which is driven by a belt connected to one or more engines/motors. |
