Abstract

A blackbody material application system for a turbine. The system includes a blackbody material supply and a moveable hose connected to the blackbody material supply wherein the hose sprays blackbody material onto a selected area within the turbine. The system also includes a rotatable bracket that holds the hose, wherein rotation of the bracket moves the hose toward the selected area within the turbine to enable application of the blackbody material onto the selected area. In addition, the system includes a motor for rotating the bracket and a moveable arm that holds the bracket wherein the bracket is inserted through an opening in the turbine and movement of the arm enables positioning of the bracket and hose in relative close proximity to the selected area suitable for spraying blackbody material onto the selected area.

First claim

What is claimed is:

1. A blackbody material application system for a turbine, comprising:
a blackbody material supply;
a moveable hose connected to the blackbody material supply wherein the hose sprays blackbody material onto a selected area within the turbine;
a rotatable bracket that holds the hose, wherein rotation of the bracket moves the hose toward the selected area within the turbine to enable application of the blackbody material onto the selected area; and
a motor for rotating the bracket.

2. The system according to claim 1 , wherein the bracket is rotatable about a vertical axis.

3. The system according to claim 1 , wherein the bracket further includes a camera and a lamp to enable viewing of components and surfaces located within the turbine to assist in positioning the bracket and hose relative to the selected area.

4. The system according to claim 1 , wherein the blackbody material is a graphite based paint.

5. The system according to claim 4 , wherein the blackbody material supply includes an air supply for drawing the graphite into an air channel to form a spray.

6. The system according to claim 1 , wherein the blackbody material is sprayed in a substantially cone shaped pattern.

7. The system according to claim 1 , wherein the system is located within an enclosure that protects the system from blackbody material overspray.

8. The system according to claim 1 , wherein the selected area includes a thermal barrier coating and/or a bond coating.

9. A blackbody material application system for a turbine, comprising:
a blackbody material supply;
a moveable hose connected to the blackbody material supply wherein the hose sprays blackbody material onto a selected area within the turbine;
a rotatable bracket that holds the hose, wherein rotation of the bracket moves the hose toward the selected area within the turbine to enable application of the blackbody material onto the selected area;
a motor for rotating the bracket; and
a moveable arm that holds the bracket wherein the bracket is inserted through an opening in the turbine and movement of the arm enables positioning of the bracket and hose suitable for spraying blackbody material onto the selected area.

10. The system according to claim 9 , wherein the bracket is rotatable about a vertical axis.

11. The system according to claim 9 , wherein the bracket further includes a camera and a lamp to enable viewing of components and surfaces located within the turbine to assist in positioning of the bracket and hose relative to the selected area.

12. The system according to claim 9 , wherein the blackbody material is a graphite based paint.

13. The system according to claim 12 , wherein the blackbody material supply includes an air supply for drawing the graphite into an air channel to form a spray.

14. The system according to claim 12 , wherein the blackbody material is sprayed in a substantially cone shaped pattern.

15. The system according to claim 9 , wherein the system is located within an enclosure that protects the system from blackbody material overspray.

16. The device according to claim 9 , wherein the selected area includes a thermal barrier coating and/or a bond coating.

17. A method for applying blackbody material onto a selected area inside a turbine, comprising:
providing a blackbody material supply;
providing a moveable hose connected to the blackbody material wherein the hose sprays blackbody material onto the selected area within the turbine;
providing a rotatable bracket that holds the hose, wherein rotation of the bracket moves the hose toward the selected area within the turbine to enable application of the blackbody material onto the selected area;
providing a motor for rotating the bracket; and
providing a moveable arm that positions the bracket and hose inside the turbine suitable for spraying blackbody material onto the selected area.

18. The method according to claim 17 , wherein the bracket is rotatable about a vertical axis.

19. The method according to claim 17 , wherein the bracket further includes a camera and a lamp to enable viewing of components and surfaces located within the turbine to assist in positioning of the bracket and hose relative to the selected area.

20. The method according to claim 17 , wherein the blackbody material is a graphite based paint.
