Combustor heat shield panel
A combustor for use in a gas turbine engine, the combustor enclosing a combustion chamber having a combustion area. The combustor includes: a shell having a kink; and a kinked heat shield panel in facing spaced relationship with the shell, the kinked heat shield panel including a kink located proximate the kink in the shell, wherein the kinked heat shield panel further includes a first surface, a second surface opposite the first surface, and a mounting stud located proximate the kink of the kinked heat shield panel and extending away from the second surface.
1. A combustor for use in a gas turbine engine, the combustor enclosing a combustion chamber having a combustion area, wherein the combustor comprises:
a shell having a kink, wherein the kink is a v-shaped bend; and
a kinked heat shield panel in facing spaced relationship with the shell, the kinked heat shield panel including a kink located proximate the kink in the shell, wherein the kink in the heat shield panel is a v-shaped bend,
wherein the kinked heat shield panel further comprises a first surface, a second surface opposite the first surface, and a mounting stud located proximate the kink of the kinked heat shield panel and extending away from the second surface,
wherein the shell further comprises an inner surface, an outer surface opposite the inner surface, and a mounting orifice extending through the shell from the inner surface to the outer surface, the mounting orifice being located proximate the kink of the shell, and
wherein the mounting orifice is located at or on the kink of the shell.
2. The combustor of claim 1 , wherein the kinked heat shield panel is parallel to the shell.
3. The combustor of claim 1 , wherein the combustor comprises a first section and a second section, wherein the kink of the shell is a junction of the first section of the combustor having a first coned shape and the second section of the combustor having a second coned shape.
4. The combustor of claim 1 , wherein the kink of the shell is a point in the shell at which a cross sectional area of the combustor changes.
5. The combustor of claim 1 , wherein the mounting stud is located at or on the kink of the kinked heat shield panel.
6. The combustor of claim 1 , wherein the mounting orifice is located opposite the mounting stud.
7. The combustor of claim 1 , wherein the kinked heat shield panel further comprises a forward edge, a rearward edge opposite the forward edge, a first lateral edge, and a second lateral edge opposite the first lateral edge, wherein the first lateral edge and the second lateral edge extend from the forward edge to the rearward edge, and wherein the kink of the kinked heat shield panel extends from the first lateral edge to the second lateral edge.
8. The combustor of claim 7 , wherein the kink of the kinked heat shield panel extends from the first lateral edge to the second lateral edge parallel to at least one of the forward edge and the rearward edge.
9. The combustor of claim 8 , wherein the kinked heat shield panel further comprises a locating pin located proximate the mounting stud and extending away from the second surface, wherein the locating pin further comprises a platform surface operably shaped to conform to the inner surface of the shell opposite the locating pin.
10. The combustor of claim 8 , further comprising:
a nut secured to the mounting stud; and
a kinked washer interposed between the nut and the outer surface of the shell, the kinked washer being operably shaped to conform to the outer surface of the shell proximate the kink of the shell.
11. The combustor of claim 10 , wherein the kinked washer further comprises a first surface proximate the outer surface of the shell and a second surface opposite the first surface of the kinked washer, the second surface of the kinked washer being proximate the nut, and wherein the first surface of the kinked washer is operably shaped to conform to the outer surface of the shell proximate the kink of the shell.
12. The combustor of claim 11 , wherein the second surface of the kinked washer is operably shaped to conform to the nut.
13. The combustor of claim 10 , wherein the kinked washer further comprises a receiving orifice extending through the kinked washer from the first surface to the second surface, the mounting stud being located within the kinked orifice.
14. The combustor of claim 1 , wherein the mounting orifice is circular, oval or slotted in shape.
15. The combustor of claim 7 ,
wherein the mounting stud is located proximate at least one of the first lateral edge and the second lateral edge.
16. The combustor of claim 7 ,
wherein the mounting stud is centered between the first lateral edge and the second lateral edge.
