Abstract

Systems and methods involving rotable gas turbine engine components are provided. In this regard, a representative system includes: a component pool control system; an inventory system operative to store inventory information corresponding to a current inventory of rotable components and to provide the inventory information to the component pool control system; and an inspection system operative to store inspection information corresponding to analyzed one of the rotable components and to provide the inspection information to the component pool control system.

Claims

1. A method involving rotable gas turbine engine components comprising:

obtaining access to a rotable component;

analyzing the component;

removing a corresponding rotable component from service;

replacing the removed component with the component previously analyzed;

analyzing the removed component;

determining that the component and the corresponding component exhibit different operational usage times; and

correlating information obtained during the analyzing of the component and the corresponding component relative to the usage times.

2. The method of claim 1, wherein obtaining access to the component comprises purchasing the component.

3. The method of claim 1, wherein analyzing the component comprises determining at least one operational characteristic of the component.

4. The method of claim 1, wherein analyzing the component comprises determining cooling airflow requirements of the component.

5. The method of claim 1, wherein the component is a turbine vane.

6. The method of claim 5, wherein the removed component is a turbine vane having a corresponding part number to that of the component.

7. The method of claim 1, wherein removing the corresponding component comprises removing the corresponding component during a maintenance procedure on an engine in which the corresponding component is installed.

8. The method of claim 1, further comprising determining whether authority to swap the component exists prior to removing the corresponding component from service such that the removing of the corresponding component from service and the replacing of the removed component with the component previously analyzed does not occur unless the authority to swap exists.

9. The method of claim 1, further comprising analyzing maintenance schedules such that the corresponding component and associated time period for removal are identified.

10. A system involving rotable gas turbine engine components comprising:

a component pool control system;

an inventory system operative to store inventory information corresponding to a current inventory of rotable components and to provide the inventory information to the component pool control system; and

an inspection system operative to store inspection information corresponding to analyzed one of the rotable components and to provide the inspection information to the component pool control system.

11. The system of claim 10, wherein the component pool control system is operative to determine the components to be removed from service.

12. The system of claim 11, wherein the component pool control system is operative to determine the components to be removed from service based, at least in part, on the current inventory.

13. The system of claim 10, wherein the component pool control system is operative to determine an appropriate periodic maintenance cycle available for removal of a rotable component.

14. The system of claim 10, wherein the inventory information and the inspection information is provided to the component pool control system via a communication network.

15. The system of claim 10, wherein the inspection system is operative to store inspection information corresponding to at least one of:

component geometry, base material chemistry and microstructure, coating chemistry and microstructure, airflow characteristics, previous repair.

16. The system of claim 10, wherein the inventory system is operative to store inventory information corresponding to at least one of the following:

part number, serial numbers of the components, current locations of the components, quantities of the components, conditions of the components, interchangability requirements with other part numbers, nozzle areas, base materials, coating materials, and value.

17. The system of claim 10, wherein the inventory system is operative to store inventory information corresponding to at least one of information regarding the availability of uninstalled components and predicted availability of currently installed components.

18. A method involving rotable gas turbine engine components comprising:

analyzing a component;

removing a corresponding component from an aircraft engine based, at least in part, on a request for obtaining information pertaining to the corresponding component, the request being provided by a component pool control system that is operative to coordinate compilation of a database of information corresponding to rotable components;

replacing the removed component with the component previously analyzed;

analyzing the removed component;

enabling the component pool control system to augment the database with information corresponding to the component and to the corresponding component; and

using information form the database to facilitate at least one of repair and replacement of another corresponding component.

19. The method of claim 18, wherein analyzing the component comprises determining at least one operational characteristic of the component.

20. The method of claim 19, wherein analyzing the component comprises determining cooling airflow requirements of the component.
