Abstract

An aerial refueling assembly includes, for example, a pressure transducer, a processor, and one or more light sources. The processor is coupled to the pressure transducer. The one or more light sources are coupled to the processor. The pressure transducer is configured to sense a fuel pressure inside the aerial refueling assembly and to provide a signal that is indicative of the sensed fuel pressure inside the aerial refueling assembly. The processor is configured to receive the signal and to cause the one or more light sources to flash in a manner that relates to the sensed fuel pressure.

First claim

What is claimed is:

1. An aerial refueling assembly, comprising:
a pressure transducer;
a processor coupled to the pressure transducer;
a fuel dispensing end portion, positionable distally from a first aircraft and configured to interface directly with a probe of a second aircraft, the probe configured to receive fuel from the first aircraft via the fuel dispensing end portion; and
one or more light sources operably coupled to the processor and secured to the fuel dispensing end portion,
wherein the pressure transducer is configured to sense a fuel pressure inside the aerial refueling assembly and to provide a signal that is indicative of the sensed fuel pressure inside the aerial refueling assembly,
wherein the processor is configured to receive the signal and to cause the one or more light sources to flash in a manner that indicates a status of a grip between the fuel dispensing end portion and the probe of the second aircraft.

2. The aerial refueling assembly according to claim 1 , wherein the one or more light sources include one or more light emitting diodes.

3. The aerial refueling assembly according to claim 1 , wherein the one or more light sources include one or more infrared light emitting diodes.

4. The aerial refueling assembly according to claim 1 , wherein the processor is configured to receive the signal and to cause the one or more light sources to flash at a rate that indicates a status of a grip between the fuel dispensing end portion and the probe of the second aircraft.

5. The aerial refueling assembly according to claim 1 , wherein the processor is configured to receive the signal and to cause the one or more light sources to flash in a pattern that relates to the sensed fuel pressure.

6. The aerial refueling assembly according to claim 1 , wherein the pressure transducer is configured to sense a fuel pressure inside a drogue assembly of the aerial refueling assembly and to provide a signal that is indicative of the sensed fuel pressure inside the drogue assembly of the aerial refueling assembly.

7. The aerial refueling assembly according to claim 1 , wherein the one or more light sources include one or more of the following: a fluorescent light source, a neon light source, a laser light source, and an incandescent light source.

8. A method for determining a fuel pressure inside an aerial refueling assembly, comprising:
sensing, via a sensor, a fuel pressure inside an aerial refueling assembly;
controlling, by a processor, one or more light sources to flash, the one or more light sources secured to a fuel dispensing end portion of the aerial refueling assembly, the fuel dispensing end portion being positionable on the aerial refueling assembly distally from a first aircraft and configured to interface directly with a probe of a second aircraft to provide fuel from the first aircraft to the second aircraft, wherein the processor controls the one or more light sources to flash in a manner that indicates a status of a grip between the fuel dispensing end;
receiving, via a camera, the flashing from the one or more light sources; and
displaying, on a display, a view of a portion of the aerial refueling assembly including the flashing from the one or more light sources.

9. The method according to claim 8 , wherein the one or more light sources include one or more infrared light emitting diodes.

10. The method according to claim 8 , wherein the one or more light sources include one or more infrared light sources.

11. The method according to claim 8 , comprising:
sending a signal to the processor, wherein the signal is related to the sensed fuel pressure; and
processing the signal by the processor to output another signal that causes the one or more light sources to flash at rate that relates to the sensed fuel pressure.

12. The method according to claim 8 , comprising:
sending a signal to the processor, wherein the signal is related to the sensed fuel pressure; and
processing the signal by the processor to output another signal that causes the one or more light sources to flash in a pattern that relates to the sensed fuel pressure.

13. The method according to claim 8 , wherein the sensed fuel pressure inside the aerial refueling assembly is the fuel pressure inside a drogue assembly of the aerial refueling assembly.

14. A system for determining a fuel pressure inside an aerial refueling assembly, comprising:
a sensor system that includes a pressure transducer, a processor, one or more light sources, and a fuel dispensing end tethered to a first aircraft, positionable distally from the first aircraft, and configured to interface directly with a probe of a second aircraft to provide fuel to the second aircraft from the first aircraft, wherein the processor is coupled to the pressure transducer, wherein the one or more light sources are coupled to the processor and secured to the fuel dispensing end, wherein the pressure transducer is configured to sense a fuel pressure inside the aerial refueling assembly and to provide a signal that is indicative of the sensed fuel pressure inside the aerial refueling assembly, wherein the processor is configured to receive the signal and to cause the one or more light sources to flash in a manner that indicates a status of a grip between the fuel dispensing end and the probe of the second aircraft; and
a vision system that includes a camera and a display, wherein the flashing from the one or more light sources is captured by the camera and displayed as a video on the display.

15. The system according to claim 14 , wherein the flashing displayed on the display is a real-time indication of fuel pressure in a drogue assembly of the aerial refueling assembly.

16. The system according to claim 14 , wherein the sensor system is part of a drogue assembly of the aerial refueling assembly.

17. The system according to claim 14 , wherein the one or more light sources include one or more infrared light emitting diodes.

18. The system according to claim 14 , wherein the one or more light sources include one or more infrared light sources.

19. The system according to claim 14 , wherein the processor is configured to receive the signal and to cause the one or more light sources to flash at a rate that relates to the sensed fuel pressure of a drogue assembly of the aerial refueling assembly.

20. The system according to claim 14 , wherein the processor is configured to receive the signal and to cause the one or more light sources to flash in a pattern that relates to the sensed fuel pressure of a drogue assembly of the aerial refueling assembly.
