SIGNAL GENERATOR FOR AN UNMANNED AIRCRAFT, UNMANNED AIRCRAFT, AND METHOD OF GENERATING A SIGNAL AT AN UNMANNED AIRCRAFT

Abstract

The invention relates to a signal generator for unmanned aircraft comprising at least one light source and/or at least one sound source and at least one regulator/control for actuating the at least one source.

Claims

1. A signal generator for unmanned aircraft comprising at least one light source and/or at least one sound source as well as at least one regulation/control for actuating the at least one light source and/or the at least one sound source, wherein in that the at least one light source and/or sound source is actuable in dependence on at least one state of danger.

2. The signal generator in accordance with claim 1, wherein the state of danger is a controlled and/or uncontrolled crash and/or a collision of the aircraft, with a device being provided for recognizing a corresponding state of danger.

3. The signal generator in accordance with claim 2, wherein the device comprises a navigation device that is adapted to transmit information to the regulation/control for actuating the light source or the sound source.

4. The signal generator in accordance with claim 2, wherein the device comprises an independent trigger system inherent to the system.

5. The signal generator in accordance with claim 1, wherein the sound source is electrically and/or pneumatically operated.

6. The signal generator in accordance with claim 1, wherein the regulation/control is adapted to actuate the light source or the sound source on an exceeding of at least one basic parameter.

7. The signal generator in accordance with claim 6, wherein the basic parameter is a horizontal and/or vertical flight attitude and/or a speed parameter of the aircraft.

8. The signal generator in accordance with claim 1, wherein the signal output by the light source or sound source is a single signal and/or a multiple signal and/or a continuous signal and/or an interval signal; and/or in that the signal output by the light source or sound source is variable in its frequency.

9. An unmanned aircraft having at least one signal generator comprising at least one light source and/or at least one sound source as well as at least one regulation/control for actuating the at least one light source and/or the at least one sound source, wherein in that the at least one light source and/or sound source is actuable in dependence on at least one state of danger.

10. A method of generating a signal at an unmanned aircraft, the method comprising the steps: recognizing a state of danger; generating a signal in dependence on the state of danger.

11. The method of claim 10 wherein the signal generator comprises at least one light source and/or at least one sound source as well as at least one regulation/control for actuating the at least one light source and/or the at least one sound source, wherein in that the at least one light source and/or sound source is actuable in dependence on at least one state of danger to generate the signal.

Description

[0030] Further details and advantages of the invention are explained with reference to the embodiment shown by way of example in FIG. 1.

[0031] The only FIG. 1 shows the schematic view of an unmanned aircraft 1 in accordance with the invention that can be configured as a multicopter. The aircraft 1 can comprise a plurality of motors, in particular electric motors, and thus in particular directly coupled propellers, that is propellers coupled without a transmission.

[0032] At least one light source 3 and/or at least one sound source 2 can be provided at a lower side of the aircraft 1. The light source 3 and the sound source 2 can be actuated or engaged via a regulation/control.

[0033] The light source 3 and/or the sound source 2 can in particular transmit light or sound downwardly in a manner directed away from the aircraft 1.

[0034] It is conceivable that both a light source 3 and a sound source 2 are provided. Means for recognizing a state of danger can be provided at the aircraft 1.

[0035] The means can, for example, comprise a navigation device that is adapted to transmit information to a regulation/control, not shown, of the aircraft.

[0036] The aircraft 1 can comprise an internal navigation system, an independent trigger system 4 inherent to the system, or other means of recognizing a state of danger. They can be coupled to the regulation/control and can influence the triggering of the sound source 2 and/or of the light source 3.
