Abstract

A method of assembling a gas turbine engine is provided that includes locating a consumable assembly tool within the engine. The consumable assembly tool is attached to another component of the gas turbine engine. The engine is run to vaporize the consumable assembly tool.

Claims (33)

1. A method of assembling a gas turbine engine, comprising:

locating a consumable assembly tool within the engine, wherein the consumable assembly tool is a consumable component of the gas turbine engine;

gluing the consumable assembly tool to another component of the gas turbine engine; and

running the engine to completely vaporize the consumable assembly tool;

wherein the consumable assembly tool comprises a polymer; and

wherein the consumable assembly tool is a wholly discretely formed body.

2. The method as recited in claim 1 , wherein the gluing of the consumable assembly tool occurs within the engine.

3. The method as recited in claim 1 , wherein the gluing the consumable assembly tool occurs within the engine as a multiple of segments.

4. The method as recited in claim 1 , wherein the gluing of the consumable assembly tool occurs within the engine as a full hoop.

5. The method as recited in claim 1 , wherein the gluing of the consumable assembly tool to the other component of the gas turbine engine occurs prior to assembly of the other component into the engine.

6. The method as recited in claim 1 , wherein the other component is one of a plurality of other components to which the consumable assembly tool is glued prior to assembly of the multiple of components as a unit into the engine.

7. The method as recited in claim 1 , further comprising locating the consumable assembly tool to operate as an assembly stop.

8. The method as recited in claim 1 , further comprising locating the consumable assembly tool within an axially movable assembly of the engine to operate as an assembly stop for the axially movable assembly.

9. The method as recited in claim 1 , further comprising locating the consumable assembly tool adjacent to a Blade Outer Air Seal (BOAS) assembly to operate as an assembly stop, wherein the Blade Outer Air Seal (BOAS) assembly comprises the other component.

10. The method as recited in claim 1 , further comprising locating the consumable assembly tool adjacent to a flexible component.

11. The method as recited in claim 1 , further comprising locating the consumable assembly tool adjacent to a W-seal.

12. The method as recited in claim 1 , further comprising locating the consumable assembly tool within an axially movable assembly of the engine.

13. The method as recited in claim 1 , wherein the polymer comprises polyethylene.

14. The method as recited in claim 1 , wherein the consumable assembly tool is configured to be vaporized during a first running of the gas turbine engine.

15. A method, comprising:

disposing glue onto the consumable assembly tool;

locating a consumable assembly tool within a gas turbine engine, the consumable assembly tool comprising a polymer, wherein the consumable assembly tool is a wholly discretely formed body; and

running the gas turbine engine, the consumable assembly tool being completely consumed during the running of the gas turbine engine.

16. The method as recited in claim 15 , wherein the running of the gas turbine engine is a first running of the gas turbine engine.

17. The method as recited claim 15 , wherein the polymer comprises polyethylene.

18. The method as recited in claim 15 , further comprising gluing the consumable assembly tool within the gas turbine engine.

19. A method of assembling a gas turbine engine, comprising:

receiving a consumable assembly tool comprising a polymer; and

arranging the consumable assembly tool within a turbine section of the gas turbine engine, wherein the consumable assembly tool is a wholly discretely formed body;

wherein glue is disposed on the consumable assembly tool; and

wherein the consumable assembly tool is completely consumed during nominal operation of the gas turbine engine.

20. The method of claim 1 , wherein the consumable assembly tool is formed as a self-supporting body, and the consumable assembly tool is configured to be completely vaporized within the normal operating temperatures of the engine.

21. The method as recited in claim 1 , wherein the running of the gas turbine engine is a first running of the gas turbine engine.
