PREFERRED EMBODIMENTS OF THE INVENTION

[0042] FIG. 1 shows a multi-rotor aircraft known from the prior art as unmanned aircraft, which is embodied as quadrocopter. A sensor unit in the form of a camera is positioned below the centrally arranged aircraft components in an exemplary manner.

[0043] FIG. 2 schematically shows the modular setup using the example of a quadrocopter. In the center, the unmanned aircraft 100 has the payload sensing system 11. The payload sensing system 11 substantially consists of a sensor system 11a, which is arranged in and fastened to a frame 17. The rotors 13 are arranged on the drive modules 10a, 10b, 10c, 10d. The drive modules 10a, 10b, 10c, 10d can be connected to the payload sensing system 11 or to the frame 17 of the payload sensing system 11, respectively, via a plug connection. The sensor system 11a is embodied as individual optical sensor unit here for example.

[0044] The sensor system 11a can be exchanged within the frame 17 in a simple manner. Different sensor systems 11a are shown in FIGS. 2a, 2b and 2c in an exemplary manner.

[0045] A part of the generic system architecture for an unmanned aircraft 100 is schematically shown in FIG. 3 in the form of a multi-rotor aircraft. Only the payload sensing system 11 and a drive module 10a, which is connected to the payload sensing system 11, is thereby shown in FIG. 3. The payload sensing system 11 has a plurality of coupling units 15 on the frame 17 for connecting further drive modules 10b, 10c, 10d.

[0046] The drive module 10a is embodied in the form of a rotor arm, wherein the individual aircraft components 12, namely one or a plurality of motors 12a, a power source 12b, a proximity sensor 12c, a satellite positioning system 12d, an inertial measuring system 12e and a computing unit with the possibility for wireless data transmission 12f are arranged in the interior of the rotor arm.

[0047] The generic system architecture for a winged aircraft configuration is shown in FIG. 4 in a schematic manner. Only one airfoil 14 is shown thereby. The payload sensing system 11 shown in FIG. 4 is connected to an airfoil 14 via the coupling units 15. The airfoil 14 thus forms a drive module 10a, 10b, 10c, 10d. The airfoil 14 or the drive module 10a, respectively, is connected to the coupling units 15 on the frame 17 of the payload sensing system 11 via connecting elements, for example arms. As does the rotor arm in FIG. 3, the airfoil 14 in FIG. 4 has the aircraft components 12.

[0048] The logical arrangement of the modular aircraft components 12 is shown in FIG. 5. The individual redundant aircraft components 12 of each drive module 10a, 10b, 10c, 10d are electrically connected to one another according to their function. The drive modules 10a, 10b, 10c, 10d or the aircraft components 12, which are assigned to the drive modules 10a, 10b, 10c, 10d, respectively, are electrically connected to one another via the electric connecting means 16 in the form of a bus.
