摘要:
An aerostat system with an extended flight envelope in which the aerostat system can safely operate is provided. The aerostat system includes an aerostat, multiple tether groups and a base station. Spatially distinct tether groups allow for improved stability and controllability over a wide range of wind conditions. Independent actuation of the tether groups allows for control of the aerostat pitch and roll angle. A rotating platform including rails to rest the aerostat allows docking without auxiliary tethers, minimizing or eliminating the ground crew required to dock traditional aerostat systems. An optional controller allows remote or autonomous operation of the aerostat system.

Die Erfindung betrifft einen Elektromagneten mit einer mit Strom beaufschlagbaren Spule, einem in einem Ankerraum beweglich gelagerten Anker, der durch ein sich aus der Strombeaufschlagung der Spule ergebendes Magnetfeld bewegbar ist, einem Magnetjoch, einer Ankerfeder und einem im Magnetjoch einsetzbaren Einstellstift, wobei sich die Ankerfeder einerseits am Einstellstift andererseits am Anker abstützt und über eine Eindringtiefe des Einstellstiftes in das Magnetjoch beziehungsweise den Elektromagnet die Kennlinie des Elektromagneten einstellbar ist.
摘要:
A shroud, such as for an airborne wind-turbine for converting wind energy into another form of energy, such as electrical energy. The shroud has a ring-like shape with an airfoil cross-section and defines an interior volume for containing a lighter-than-air gas. The shroud includes a central opening oriented along a longitudinal axis of the shroud. The shroud is configured to produce an asymmetric moment of left and right lateral sections thereof, which asymmetric moment yields a restoring moment that automatically orients the longitudinal axis of the shroud substantially optimally relative to a prevailing wind direction.
