Abstract

A sealing system is provided for a flanged joint. The sealing system includes a split seal and a spring. The split seal includes a radial outer surface, an axial outer surface, and a chamfered surface inclined with respect to the radial outer surface and the axial outer surface. The spring is disposed in urging contact with the chamfered surface and configured to apply an axial force, and a radial force on the axial outer surface, and the radial outer surface respectively.

First claim

I claim:

1. A sealing system for a flanged joint, the sealing system including:
a split seal including:
a radial outer surface;
an axial outer surface; and
a chamfered surface inclined with respect to the radial outer surface and the axial outer surface; and

a spring disposed in urging contact with the chamfered surface and configured to apply an axial force, and a radial force on the axial outer surface, and the radial outer surface respectively; and
wherein the flanged joint includes:
a first flange; and
a second flange releasably connected to the first flange, wherein the first and second flange together define a seal pocket including a forward surface, an aft surface, and a circumferential surface;

wherein the spring of the sealing system acts between the chamfered surface and a forward surface of the seal pocket;
wherein the forward and aft surfaces are forward and aft relative to the engine; and
wherein the sealing system is housed in the seal pocket.

2. The sealing system of claim 1 , wherein the split seal is of a polygonal cross section.

3. The sealing system of claim 1 , wherein the spring is of a round cross section.

4. The sealing system of claim 1 , wherein the spring is one of a helical spring, a marcel expander, and a wavy spring.

5. The sealing system of claim 1 , wherein the split seal is configured to restrict a passage of fluid into and out of the flanged joint.

6. The flanged joint of claim 1 , wherein the radial outer surface of the seal is urged against a circumferential surface of the seal pocket and the axial outer surface of the seal is urged against an aft surface of the seal pocket.

7. A gas turbine engine comprising:
a compressor system including a first flange;
a combustor system including a second flange releasably connected to the first flange; and
a sealing system disposed adjacent to the first and second flange, the sealing system including:
a split seal including:
a radial outer surface abutting the first flange;
an axial outer surface abutting the second flange; and
a chamfered surface inclined with respect to the radial outer surface and the axial outer surface; and

a spring disposed in urging contact with the chamfered surface and configured to apply an axial force, and a radial force on the axial outer surface, and the radial outer surface respectively.

8. The gas turbine engine of claim 7 , wherein the first and second flange together define a seal pocket including a forward surface, an aft surface, and a circumferential surface.

9. The gas turbine engine of claim 8 , wherein the sealing system is housed in the seal pocket.

10. The gas turbine engine of claim 9 , wherein the radial outer surface of the seal is urged against a circumferential surface of the seal pocket and the axial outer surface of the seal is urged against an aft surface of the seal pocket.

11. The gas turbine engine of claim 9 , wherein the spring of the sealing system acts between the chamfered surface and a forward surface of the seal pocket.

12. The gas turbine engine of claim 8 , wherein forward and aft is relative to the gas turbine engine.

13. The gas turbine engine of claim 8 , wherein the spring of the sealing system acts between the chamfered surface and the forward surface of the seal pocket.

14. A gas turbine engine comprising:
a sealing system for a flanged joint, the sealing system including:
a split seal including having a radial outer surface, an axial outer surface, and a chamfered surface inclined with respect to the radial outer surface and the axial outer surface; and
a spring disposed in urging contact with the chamfered surface and configured to apply an axial force, and a radial force on the axial outer surface, and the radial outer surface respectively.
