A method for assembling a compressor for use with a turbine is provided. The method includes coupling at least a first stator ring to a second stator ring via at least one fastener sized to extend through at least one stator ring opening. The method further includes coupling a shield assembly to at least one of the first stator ring and the second stator ring to facilitate reducing convection and aerodynamic bleed losses of the at least one stator ring. The shield assembly includes a downstream surface, a retaining portion, and a contoured upstream surface extending from the downstream surface to the retaining portion.

What is claimed is: 1. A method for assembling a compressor for use with a turbine, said method comprising: coupling at least a first stator ring to a second stator ring via at least one fastener sized to extend through at least one stator ring opening; and coupling a shield assembly to at least one of the first stator ring and the second stator ring, wherein the shield assembly includes a downstream surface, a retaining portion, and a contoured upstream surface extending from the downstream surface to the retaining portion, wherein said coupling comprises: coupling a first arcuate member to the at least one stator ring opening, wherein the first arcuate member includes at least one retaining slot defined therein; coupling a second arcuate member to at least one retainer, wherein the second arcuate member includes an aperture extending therethrough; and coupling the first arcuate member and the second arcuate member together. 2. A method in accordance with claim 1 further comprises inserting the at least one retaining portion of the shield assembly within a groove defined in at least one of the first stator ring and the second stator ring such that the shield assembly substantially shields at least one stator ring from air flowing past at least one stator ring. 3. A method in accordance with claim 1 wherein coupling a shield assembly to at least one of a first stator ring and a second stator ring further comprises coupling the shield assembly to the stator ring to facilitate reducing aerodynamic bleed losses of the stator ring. 4. A method in accordance with claim 1 wherein coupling a shield assembly to at least one of a first stator ring and a second stator ring comprises: providing a plurality of shield segments that each have a first arcuate member, a second arcuate member, and a body extending therebetween; coupling the first arcuate member of a first shield segment and the second arcuate member of second shield segment together such that fluid leakage between the first and second shield segments is facilitated to be reduced. 5. A method in accordance with claim 1 wherein coupling the first arcuate member to the at least one stator ring opening further comprises coupling the at least one retaining slot to the at least one stator ring opening by securing the at least one retaining slot in position with at least one nut coupled to the at least one fastener. 6. A method in accordance with claim 1 wherein coupling the second arcuate member to at least one retainer further comprises securing the shield assembly second arcuate portion in position with respect to the at least one of the first stator ring and the second stator ring by positioning the at least one retainer in at least one stator ring and extending a pin through the at least one retainer. 7. A turbine assembly comprising: a compressor assembly with at least one flange coupled to at least one stator ring via at least one fastener sized to extend through at least one stator ring opening; and a shield assembly coupled to said at least one stator ring, wherein said shield assembly comprises a downstream surface, a retaining portion, and a contoured upstream surface extending from said downstream surface to said retaining portion, wherein said shield assembly comprises a first arcuate member and a second arcuate member coupled together, wherein said first arcuate member comprises at least one retaining slot defined therein, wherein said second arcuate member further comprises an aperture extending therethrough, wherein said first arcuate member is coupled to said at least one stator ring opening, and wherein said second arcuate member is coupled to at least one retainer extending through said at least one stator ring. 8. A turbine assembly in accordance with claim 7 wherein said shield assembly retaining portion is inserted within a groove defined in the at least one stator ring such that said shield assembly substantially shields said at least one stator ring from air flowing past said at least one stator ring. 9. A turbine assembly in accordance with claim 7 wherein said at least one flange is coupled to said at least one stator ring such the said flange extends downstream from said stator ring, and said shield assembly is coupled to said at least one stator ring to facilitate reducing windage losses of said at least one stator ring. 10. A turbine assembly in accordance with claim 7 wherein said shield assembly retaining slot is coupled to said at least one stator ring opening, wherein said retaining slot is secured in position with at least one nut coupled to said at least one fastener. 11. A turbine assembly in accordance with claim 7 wherein said shield assembly further comprises of a plurality of shield segments, wherein each shield segment comprises a first arcuate member, a second arcuate member, and a body extending therebetween, wherein said first arcuate member of a first shield segment is coupled to said second arcuate member of a second shield segment such that fluid leakage between said first shield segment and said second shield segment is facilitated to be reduced. 12. A compressor assembly for use with a turbine, said compressor assembly comprising: at least one flange coupled to at least one stator ring via at least one fastener sized to extend through at least one stator ring opening; and a shield assembly coupled to said at least one stator ring, said shield assembly comprises a downstream surface, a retaining portion, and a contoured upstream surface extending from said downstream surface to said retaining portion, wherein said shield assembly further comprises a first arcuate member and a second arcuate member coupled together, wherein said first arcuate member comprises at least one retaining slot defined therein, wherein said second arcuate member further comprises an aperture extending therethrough, wherein said first arcuate member is coupled to said at least one stator ring opening, and wherein said second arcuate member is coupled to at least one retainer extending through said at least one stator ring. 13. A compressor assembly in accordance with claim 12, said shield assembly retaining portion is inserted within a groove defined in said at least one stator ring such that said shield assembly substantially shields said at least one stator ring from air flowing past said at least one stator ring. 14. A compressor assembly in accordance with claim 12 wherein said at least one flange is coupled to said at least one stator ring such that said flange extends downstream from said stator ring, and said shield assembly is coupled to said at least one stator ring to facilitate reducing windage losses of said at least one stator ring. 15. A compressor assembly in accordance with claim 12 wherein said shield assembly further comprises of a plurality of shield segments, wherein each shield segment comprises a first arcuate member, a second arcuate member, and a body extending therebetween, wherein said first arcuate member of a first shield segment couples to said second arcuate member of a second shield segment such that fluid leakage between said first shield segment and said second shield segment is facilitated to be reduced. 16.
