Abstract:
An aerial observation system is described and comprises a tethered aerial platform and a plurality of ground-based monitoring devices. The aerial platform carries a payload comprising a plurality of fixed focal length cameras mounted at selected positions about the aerial platform and communication means connected to the plurality of cameras for transmitting, independently to each of the plurality of ground-based monitoring devices, a data signal comprising image data captured by one or more of the plurality of cameras. Each ground-based monitoring device is independently operable to select and display an image area of interest from the image data contained in the data signal. By utilising fixed focal length cameras instead of the normal (but much heavier, more delicate and more power-hungry) pan, tilt and zoom cameras conventionally used in such application, sensor payload on the balloon can be reduced, robustness can be increased, and battery life improved. Moreover, multiple users are able to independently access different fields of view simply by selecting different image areas out of the image data transmitted (potentially to all base stations) from the aerial platform.
Abstract:
A flying robot (1) which is carried by a gas balloon for use in interior spaces is proposed, wherein the gas balloon (2) can be adjusted in such a way that a horizontal hovering height which is provided or predefined can be adjusted or implemented. Working devices (5) are located in a valve unit (3) and/or a housing which is arranged underneath the gas balloon (2). Together with the valve unit (3) or the housing, a drive unit (4) whose direction can be adjusted is provided with respect to said unit and said housing for moving the flying robot (1). The flying robot can be used both for monitoring tasks and for filming.

Abstract:
Task of the invention is an autonomous stratospheric unmanned airship (10) with the operating altitude from 5 to 22 km and with the operational cycle measured in months. Spheroid rigid frame of constant volume is done as a geodesic frame (11) formed by a multitude of struts (28), with an outer envelope (12) enclosing the frame (11) defining the eigenfrequency spectrum of the airship (10) in the frequency range above 20 Hz, with the vibrational amplitudes between 0,1 and 1 cm. Independently controllable electrical propulsion units (14) are attached to the frame (11) in the horizontal plane passing through the center of mass, and can change the direction and the value of the thrust vector. Buoyancy is controlled with a system integrated inside the geodesic frame (11) consisting of pressurized tanks (23) containing buoyant fluid, valves (24) for the release of the buoyant fluid through the buoyant fluid conduit (26) into the buoyant gas cell (38) which by expansion fills the geodesic frame (11); and valves (18) placed at the subsystem support platform (17) enabling ambient atmosphere to fill the internal volume of the frame (11) not occupied by the buoyant gas cell (38). Additionally, inside the frame (11) is a power system comprised of batteries (32) and photovoltaic cells (13) placed at the upper part of the envelope (12). Besides the communication system (36, 37) and antennas (19, 20) airship has a control unit (32) and a specialized scientific equipment for various purposes placed at the platform (17) in a form of payload (34).

Abstract:
An aerial load lifting system features a non-rigid or blimp-type dirigible providing a lighter-than-air envelope (10) that is placed within a structural shell (50). The system is designed so that the envelope provides essentially neutral buoyancy for the structure, leaving only the cargo weight (20) to be lifted by the rotors (200). The structural shell supports the engine (100), fuel tank (42), rotors, and transmission system (120) that power the lift and vectoring of the aircraft, in addition to supporting the cargo load. The structural shell transfers the weight of the load directly to the location of the rotors, thus avoiding stress on the envelope.
Abstract:
An orientation system is disclosed for a lighter-than-air aircraft having a lower stage suspended from an envelope. The orientation system includes cords interconnecting the envelope and the lower stage and means for adjusting the length of at least one of the cords between the lower stage and the envelope. Adjusting the length produces a shift in the angle of attack of the envelope with respect to the lower stage.
