Abstract: An assembly for arrangement to the surface of an aerodynamic profile comprises an array of actuators, which are designed as piezo actuators and plasma actuators.

Abstract: This relates to a holding apparatus for holding a component during mounting. The holding apparatus comprises at least a first holding unit including at least one magnetic field generating device for generating a magnetic field, and at least a second magnetic holding unit spaced apart from the first holding unit in a predetermined distance for receiving the component. A holding force for holding the component between the first holding unit and the second holding unit is generated in the second magnetic holding unit as a result of induction and by means of a magnetic field generated by the magnetic field generating device. The embodiment also comprises a mounting system and a method for holding components by means of such holding apparatuses.

Abstract: This relates to an inspection apparatus for inspecting a structural component to which access is restricted, comprising a movable unit including a superconductor and an inspection device, a drive unit including a magnetic field generator adapted to generate a magnetic field, wherein said movable unit and said drive unit are arranged with a predetermined gap therebetween for receiving said structural component and are coupled in a force-locking manner by means of the frozen magnetic flux, i.e., without a physical connection, between the magnetic field generator and the superconductor. Thus, spaces or areas to which access is restricted can be inspected without the need of physically connecting the drive unit and the movable unit.

Abstract: A vehicle body includes a primary vehicle structure and interior vehicle fittings as well as a coupling device for fastening the interior vehicle fittings to the primary vehicle structure. The coupling device is configured to generate a magnetic field, so as to fasten the interior vehicle fittings to the primary vehicle structure without contact. Methods for assembling a vehicle body as well as an edifice are also described.

Abstract: Magnetically active elements, namely magnets or superconducting elements respectively, are incorporated respectively in an air vehicle and in a guide path on which the air vehicle is to land, take-off and/or taxi. A cooling apparatus may be provided to cool the superconducting elements. The magnets may be electromagnets, and an electrical energy source and a controller are provided to energize the electromagnets in an independently controlled manner. The magnets produce a magnetic field, and the superconducting elements expel the magnetic field and cause a quantum levitation effect, by which the air vehicle is supported in a contact-free manner above the guide path. Thus, the air vehicle may omit mechanical landing gear.

Abstract: An apparatus for removing harmful gas components out of the earth's atmosphere is a free-flying autonomous lightweight aircraft with an onboard gas processing system including gas separation or extraction devices, and inlets and outlets connected to the devices. Solar cells and/or thermoelectric generators provided on the craft produce electrical energy to operate the individual devices. The system may include a cryogenic closed-loop circulation system that participates in liquefying the extracted gas components. The apparatus is preferably a lighter-than-air craft like a dirigible. A method of extracting harmful gas components from the atmosphere involves flying the apparatus at a prescribed altitude level and operating the gas processing system to remove the harmful gas component from the atmosphere, then returning the apparatus to earth to offload the liquefied stored harmful gas component.
