Abstract

A sanitization system for an aircraft may comprise: a lighting system disposed in the aircraft cabin, the lighting system including a plurality of sanitization lights, the plurality of sanitization lights configured to emit UV-C radiation; an electrical port in electrical communication with the lighting system; an external power source disposed away from the aircraft; and an electrical cable coupled to the external power source, the electrical cable configured to removably couple to the electrical port to provide electrical power to the plurality of sanitization lights.

Claims (48)

1. A sanitization system, comprising:

an aircraft including:

an interior and an exterior:

an aircraft cabin disposed in the interior of the aircraft; and

a first electrical system, comprising:

a lighting system disposed in the aircraft cabin, the lighting system including a plurality of sanitization lights, the plurality of sanitization lights configured to emit UV-C radiation;

a sensor configured to detect whether the aircraft cabin is empty;

an electrical port disposed on the exterior of the aircraft and in electrical communication with the lighting system;

a second electrical system comprising:

a first power source; and

a plurality of cabin lights, wherein the second electrical system is independent from the first electrical system; and

a ground service cart configured to be disposed external from the aircraft during operation of the sanitization system, the ground surface cart including:

a housing;

an external power source disposed in the housing and away from the aircraft during operation of the sanitization system;

an electrical cable coupled to the external power source, the electrical cable configured to removably couple to the electrical port to exclusively provide electrical power to the plurality of sanitization lights; and

a controller configured to be operably coupled to the plurality of sanitization lights via the electrical cable, wherein in response to coupling the electrical cable to the electrical port the controller is configured to subsequently perform the following operations:

receive, through the sensor, sensor data;

determine from the sensor data whether the aircraft cabin should be empty; and

command the plurality of sanitization lights to emit the UV-C radiation for a predetermined period of time.

2. The sanitization system of claim 1 , wherein a first light in the plurality of sanitization lights is disposed above a row of seats, and wherein a second light in the plurality of sanitization lights is disposed above a walkway in the aircraft cabin.

3. The sanitization system of claim 1 , wherein the electrical cable comprises a plug, the plug configured to be removably coupled to the electrical port.

4. A sanitization system for an aircraft, the sanitization system comprising:

a ground service cart, including:

a power source disposed in the ground service cart and configured to be disposed external to the aircraft;

an electrical cable electrically coupled to the power source, the electrical cable including a plug, the plug configured to removably couple to an electrical port disposed on an exterior surface of the aircraft, wherein in response to coupling the plug to the electrical port disposed on the exterior surface of the aircraft, the power source is configured to electrically power a plurality of lights disposed within the aircraft; and

a controller operably coupled to the power source, the controller configured to be operably coupled to the plurality of lights via the electrical cable, wherein in response to coupling the plug to the electrical port disposed on the exterior surface of the aircraft, the controller configured to subsequently perform the following operations:

receive, via a sensor disposed on the aircraft, sensor data;

determine from the sensor data that the aircraft should be empty; and

command the plurality of lights disposed in a cabin of the aircraft to emit UV-C radiation for a predetermined period of time.

5. The sanitization system of claim 4 , wherein the UV-C radiation includes an average wavelength between 200 and 280 nm.

6. The sanitization system of claim 4 , further comprising the plurality of lights disposed in the cabin of the aircraft.

7. The sanitization system of claim 6 , wherein the plurality of lights are electrically coupled to the power source through the electrical port.

8. The sanitization system of claim 6 , further comprising the sensor disposed proximate the cabin of the aircraft, the sensor in communication with the controller.

9. The sanitization system of claim 8 , wherein the sensor is a motion detection sensor.

10. An aircraft, comprising:

an aircraft cabin;

a first electrical system comprising a first power source and a plurality of cabin lights, the first power source in electrical communication with the first power source, each of the plurality of cabin lights coupled to and disposed within the aircraft cabin; and

a second electrical system comprising a plurality of sanitization lights and an electrical port, each of the plurality of sanitization lights coupled to and disposed within the aircraft cabin, each of the plurality of sanitization lights configured to emit UV-C radiation in a cabin of the aircraft, each of the plurality of sanitization lights in exclusive electrical communication with the electrical port, the first electrical system being electrically isolated from the second electrical system, the electrical port disposed on an exterior of the aircraft.

11. The aircraft of claim 10 , wherein the second electrical system is not coupled to a second power source while the aircraft is in flight.

12. The aircraft of claim 10 , wherein the electrical port is configured to couple to a plug of an electrical cable, the electrical cable in electrical communication with an external power source.

13. The aircraft of claim 12 , wherein the external power source is disposed on a ground service cart.

14. The aircraft of claim 12 , further comprising a sensor disposed in the aircraft, the sensor configured to detect motion in the cabin of the aircraft.

15. The aircraft of claim 14 , further comprising a controller, wherein the sensor is configured to communicate with the controller, the controller configured to determine whether the aircraft is empty in response to receiving sensor data from the sensor.

16. The sanitization system of claim 1 , further comprising the aircraft including an aircraft body and the aircraft cabin disposed within the aircraft body, wherein:

the first electrical system is disposed within the aircraft body;

the second electrical system is disposed within the aircraft body; and

the first power source is disposed within the aircraft body.

17. The sanitization system of claim 16 , wherein the ground service cart is disposed external to the aircraft body during operation of the sanitization system.
