FRONT CENTERBODY SUPPORT FOR A GAS TURBINE ENGINE
A front center body support for a gas turbine engine includes a front center body section, a bearing section and a frustro-conical interface section, the frustro-conical interface section between the front center body section and the bearing section.
1 . A front center body support for a gas turbine engine comprising:
a front center body section defined about an axis;
a bearing section defined about said axis; and
a frustro-conical interface section defined about said axis, said frustro-conical interface section between said front center body section and said bearing section.
2 . The front center body support as recited in claim 1 , wherein said front center body section is welded to said bearing section at a weld within said frustro-conical interface section.
3 . The front center body support as recited in claim 1 , wherein said front center body section is radially outward relative to said bearing section.
4 . The front center body support as recited in claim 1 , wherein said front center body section includes mount features to receive a flex support.
5 . The front center body support as recited in claim 1 , wherein said front center body section includes an internal spline.
6 . The front center body support as recited in claim 1 , wherein said front center body section includes a fastener flange.
7 . The front center body support as recited in claim 1 , wherein said front center body section defines an annular passage with a multiple of front center body vanes.
8 . A gas turbine engine comprising:
a front center body support defined about an engine longitudinal axis;
a centering spring mounted within said front center body support; and
a flex support mounted within said front center body support.
9 . The gas turbine engine as recited in claim 8 , further comprising a bearing package mounted to said centering spring.
10 . The gas turbine engine as recited in claim 8 , further comprising a seal package mounted to said front center body support.
11 . The gas turbine engine as recited in claim 8 , wherein said front center body support includes a frustro-conical interface section defined about said axis, said frustro-conical interface section between said front center body section and said bearing section.
12 . The gas turbine engine as recited in claim 11 , further comprising a weld within said frustro-conical interface section.
13 . The gas turbine engine as recited in claim 8 , wherein said front center body support includes an internal spline which interfaces with an external spline on said flex support.
14 . The gas turbine engine as recited in claim 13 , wherein said front center body support includes an internal flange which abuts an external flange of said flex support.
15 . The gas turbine engine as recited in claim 14 , further comprising a multiple of fasteners which attach said internal flange to said external flange.
16 . The gas turbine engine as recited in claim 8 , wherein said flex support is mounted to a geared architecture.
17 . The gas turbine engine as recited in claim 16 , wherein said geared architecture drives a fans section at a speed different than a low speed spool.
18 . A method for assembling a gas turbine engine comprising:
mounting a flex support within a front center body support.
19 . The method as recited in claim 18 , further comprising:
welding a front center body section and to a bearing section at a frustro-conical interface section.
20 . The method as recited in claim 18 , further comprising:
mounting a geared architecture to the flex support.
21 . A method for maintaining a gas turbine engine comprising:
providing access from a forward section of a front center body assembly to a flex support mounted to a front center body support, the flex support mounted to a geared architecture.
22 . The method as recited in claim 21 , further comprising:
interconnecting a fan of the gas turbine engine to the geared architecture.
23 . The method as recited in claim 22 , further comprising:
disassembling the geared architecture and the fan as a unit.
24 . The method as recited in claim 23 , further comprising:
removing a multiple of fasteners located from the front center body assembly through the forward section.
25 . The method as recited in claim 24 , further comprising:
locating the multiple of fasteners to provide access from the forward section of the front center body assembly opposite a bearing package.
26 . The method as recited in claim 22 , further comprising:
assembling the geared architecture and the fan as a unit.
27 . The method as recited in claim 26 , further comprising:
inserting a multiple of fasteners into the front center body assembly through the forward section.
28 . The method as recited in claim 27 , further comprising:
assembling the multiple of fasteners to a fastener flange of the flex support and a front center body section of the front center body support.
29 . The method as recited in claim 21 , further comprising:
locating the flex support at least partially within the front center body support at a splined interface.
