A device for deploying an aerostat includes a cylindrical shaped container having an open end and a closed end and a center tube axially oriented in the container. A tapered disc is mounted for axial movement on the center tube, and it has a taper of increasing diameter in an axial direction from the closed end toward the open end of the container. In its operation, the tapered disc is held in a first position while a portion of the aerostat is loaded into the container. It is then moved to a second position wherein the tapered disc holds the loaded portion of the aerostat in the container. Thereafter, the disc is moved to a release position wherein the disc directs deployment of the aerostat from the container.

Aerostat inflator

A system and method for docking an airship to a mooring mast includes a thruster that is mounted to the fore end of the airship. When activated, the thruster generates a thrust vector that is substantially perpendicular to the longitudinal axis of the airship and is selectively directional. In particular, the configuration of the thruster can be changed to vary the direction of the thrust vector around the longitudinal axis to maneuver a connector on the thruster into contact with the mooring mast. Engagement of the connector to the mooring mast then docks the airship to the mooring mast.

Airship docking mechanism

An unmanned, lighter-than-air airship includes three omnidirectional thrust generating units. One unit is mounted at the fore-end of the airship to generate thrust in a plane that is perpendicular to the longitudinal axis of the airship. This unit controls pitch and yaw movements of the airship. The other two units are mounted on the airship equidistant from the first unit, and are located in a same midships plane that is perpendicular to the longitudinal axis. These two units generate thrust vectors that control roll movements of the airship and provide propulsion for the airship.

Tri-cycloidal airship

An airship ballast system includes an engine driven propeller and a cooling tube that is positioned coplanar with the propeller and outside its tip path. One end of the cooling tube is connected to receive exhaust gases from the engine while the other end is connected to a ballast tank. In operation, exhaust gases from the engine are cooled as they transit the cooling tube, and water condensed from the cooled exhaust gases is pumped to the ballast tank to maintain a ballast for the airship.
