Abstract

Systems and methods of servicing engines including a method of servicing an engine, the method including navigating at least a portion of a robotic assembly to a location associated with the engine; applying, from the robotic assembly, a medium to one or more adjustable components of the engine while the engine is at an elevated temperature; waiting a duration of time; and with the robotic assembly, operating on the one or more adjustable components.

Claims (29)

1. An engine servicing system comprising:

a processor configured to determine a temperature control protocol based on at least one of a design or a material of an engine component of an aircraft engine; and

a robotic assembly comprising a drive assembly, a cooling component, and a tool, the robotic assembly configured to:

navigate, with the drive assembly, to the aircraft engine while the aircraft engine is at an elevated temperature;

cause, via the cooling component, a temperature change of the engine component of the aircraft engine based on the temperature control protocol; and

perform a service or repair operation on the engine component with the tool.

2. The system of claim 1 , wherein the cooling component is to cause the temperature change by creating a temperature gradient along the engine component.

3. The system of claim 1 , wherein the temperature control protocol indicates an amount of cooling and a location of cooling to be applied to the engine component.

4. The system of claim 1 , wherein the processor is configured to determine the temperature control protocol further based on an environmental condition.

5. The system of claim 1 , wherein the processor is configured to the temperature control protocol further based on reference values, fleetwide data, and/or servicing history information.

6. The system of claim 1 , wherein the cooling component comprises a medium dispenser.

7. The system of claim 6 , wherein the medium dispenser dispenses comprises a coolant and/or lubricant.

8. The system of claim 6 , the medium dispenser applies the medium such that the medium only contacts the engine component and/or an area immediately surrounding the engine component.

9. The system of claim 1 , wherein the cooling component comprises a closed-circuit circulated coolant.

10. The system of claim 1 , wherein the cooling component comprises a thermo-electric cooler.

11. The system of claim 1 , wherein the cooling component comprises a phase change material with a relatively low melting point compared to the engine component.

12. The system of claim 1 , wherein the cooling component is configured to cause localized cooling on a male threaded fastener such that the male threaded fastener cools at a relatively faster rate than a female fastener or threads in which the male threaded fastener is disposed.

13. The system of claim 1 , wherein the robotic assembly is configured to further cause a temperature change of a next component of the aircraft engine with the cooling component while performing the service or repair operation of the engine component with the tool.

14. The system of claim 1 , wherein the robotic assembly comprises a temperature control component comprising the cooling component and a heating component.

15. The system of claim 14 , wherein the temperature control protocol comprises prescribed heating and cooling protocols.

16. The system of claim 14 , wherein the temperature control component is configured to simultaneously affect temperatures of different parts of the aircraft engine.

17. The system of claim 14 , wherein the temperature control component comprises a compressed air vortex tube configured to supply hot air to a first portion of the engine component and cold air to a second portion of the engine component.

18. The system of claim 1 , wherein the tool comprises a wrenching device and the engine component comprises a fastener; and wherein the service or repair operation comprises loosening the fastener with the wrenching device.

19. The system of claim 18 , wherein the wrenching device comprises an impulse loading means to cause shock waves to propagate through a threaded fastener.

20. A method for engine servicing comprising:

determining, with a processor, a temperature control protocol based on at least one of a design or a material of an engine component of an aircraft engine;

navigating, with a drive assembly of a robotic assembly, the robotic assembly to the aircraft engine while the aircraft engine is at an elevated temperature;

causing, via a cooling component of the robotic assembly, a temperature change of the engine component of the aircraft engine based on the temperature control protocol; and

performing a service or repair operation on the engine component with a tool of the robotic assembly.
