Abstract

A system for use in servicing a machine. The system includes a tubular body including a longitudinal axis, a tip end, a dispensing nozzle defined at the tip end, and an interior channel in flow communication with the dispensing nozzle. The tubular body is configured to be flexible. An actuator is configured to selectively modify an orientation of the tubular body, and a reservoir is in flow communication with the interior channel. The reservoir is configured to supply a maintenance fluid to the tubular body for discharge from the dispensing nozzle.

Claims (42)

1. A system for use in servicing a machine having rotating blades, the system comprising:

a tubular body comprising a longitudinal axis, a tip end, a dispensing nozzle defined at the tip end, and an interior channel in flow communication with the dispensing nozzle, wherein the tubular body is configured to be flexible;

an actuator configured to selectively modify an orientation of the tubular body;

an anchor coupled to a portion of the tubular body and configured to couple the tubular body to an attachment point within the machine and to allow the actuator to selectively modify an orientation of the tip end downstream of the anchor after the anchor couples the tubular body to the attachment point, wherein the attachment point is between two of the rotating blades to enable the rotating blades to move the tip end;

and

a reservoir in flow communication with the interior channel, wherein the reservoir is configured to supply a maintenance fluid to the tubular body for discharge from the dispensing nozzle,

wherein the actuator comprises at least one control channel extending along a length of the tubular body,

wherein the at least one control channel is selectively pressurized to selectively adjust the orientation of the tubular body.

2. The system in accordance with claim 1 wherein the anchor includes a membrane having a deflated mode for movement and an inflated mode for wedging between two of the rotating blades.

3. The system in accordance with claim 2 , wherein the actuator is configured to modify the orientation of the tip end of the tubular body relative to the attachment point.

4. The system in accordance with claim 1 , further comprising a controller using repair location data to control the actuator to selectively modify an orientation of the tubular body.

5. The system in accordance with claim 4 , wherein the controller wirelessly communicates with the actuator to selectively modify the orientation of the tubular body.

6. The system in accordance with claim 1 further comprising a camera coupled to the tip end of the tubular body.

7. The system in accordance with claim 1 , wherein the actuator comprises a pneumatic or hydraulic actuator.

8. The system in accordance with claim 1 , wherein the actuator comprises one of a pneumatic actuator, a hydraulic actuator, a cable actuator, a dielectric elastomer, an ionic polymer-metal composite, a shape memory alloy, a piezoelectric polymer, ionic conducting polymers, carbon nanotube/ionic liquid composites, ion gels, dielectric gels, functionalized hydrogels, liquid crystal polymers, or magnetic fluid/particle composite gels.

9. The system in accordance with claim 1 further comprising:

a fluid supply line extending between the tubular body and the reservoir; and

a controller configured to control the actuator.

10. The system in accordance with claim 1 further comprising a leveling device coupled to the tubular body, wherein the leveling device is configured to distribute the maintenance fluid discharged from the dispensing nozzle.

11. The system in accordance with claim 1 , wherein the tubular body includes a sidewall and the actuator includes applying pneumatic pressure or hydraulic pressure to at least one of the at least one control channel.

12. A system for use in servicing a machine, the system comprising:

a tubular assembly comprising:

a guide tube comprising an interior;

a tubular body sized for insertion within, and deployable from, the interior of the guide tube, the tubular body comprising a longitudinal axis, a tip end, a dispensing nozzle defined at the tip end, and an interior channel in flow communication with the dispensing nozzle, wherein the tubular body is configured to be flexible;

an actuator configured to selectively modify an orientation of the tubular body, wherein movement of the tubular body is restricted when positioned within the guide tube, and is unrestricted when deployed from the guide tube; and

an anchoring mechanism coupled to a portion of the tubular body, wherein the anchoring mechanism includes a first state enabling positioning entirely within the machine and a second state coupling the tubular body to an attachment point within the machine and configured to allow the actuator to selectively modify an orientation of the tip end downstream of the anchoring mechanism after the anchoring mechanism anchors the tubular body to the attachment point.

13. The system in accordance with claim 12 further comprising a reservoir in flow communication with the interior channel, wherein the reservoir is configured to supply a maintenance fluid to the tubular body for discharge from the dispensing nozzle.

14. The system in accordance with claim 13 further comprising an edge coupled to the tubular body, wherein the edge is configured to distribute the maintenance fluid discharged from the dispensing nozzle.

15. The system in accordance with claim 14 , wherein the edge is a flexible polymeric material having at least one straight edge.

16. The system in accordance with claim 12 further comprising a controller configured to control the actuator, wherein the controller is configured to receive repair location data associated with an initial inspection of the machine, and wherein the controller is configured to at least partially automate operation of the actuator based on the repair location data.

17. The system in accordance with claim 12 , wherein the actuator comprises one of a pneumatic actuator, a hydraulic actuator, a cable actuator, a dielectric elastomer, an ionic polymer-metal composite, a shape memory alloy, a piezoelectric polymer, ionic conducting polymers, carbon nanotube/ionic liquid composites, ion gels, dielectric gels, functionalized hydrogels, liquid crystal polymers, or magnetic fluid/particle composite gels.

18. The system in accordance with claim 12 , wherein the actuator comprises a plurality of control channels extending along a length of the tubular body, wherein the plurality of control channels is selectively actuatable to adjust the orientation of the tubular body.

19. The system in accordance with claim 12 , wherein the anchoring mechanism applies suction.

20. The system in accordance with claim 12 , wherein the anchoring mechanism is an inflatable membrane that inflates in the second state to facilitate immobilizing a portion of the tubular body and deflates in the first state to allow movement of the tubular body.

21. A system for use in servicing a machine, the system comprising:

a tubular body comprising a longitudinal axis, a tip end, a dispensing nozzle defined at the tip end, and an interior channel in flow communication with the dispensing nozzle, wherein the tubular body is configured to be flexible;

an actuator configured to selectively modify an orientation of the tubular body; and

a reservoir in flow communication with the interior channel, wherein the reservoir is configured to supply a maintenance fluid to the tubular body for discharge from the dispensing nozzle; and

a wedge or clamp being positioned on the tubular body to be moved by the tubular body entirely within the machine to anchor a portion of the tubular body to the machine,

wherein the actuator comprises at least one wireless control channel extending along a length of the tubular body, wherein the at least one wireless control channel is selectively actuatable to adjust the orientation of the tubular body,

wherein the tubular body includes an inner surface and an outer surface, flexible material extending from the inner surface to the outer surface along the tubular body, and the flexible material defining the at least one wireless control channel.

22. The system in accordance with claim 21 , wherein the flexible material defines at least two wireless control channels spaced about the tubular body.
