ABSTRACT:
Present gas turbine engines fail to effectively and efficiently position and locate the components making up the engine to more effectively improve engine cost, serviceability and efficiency. The present gas turbine engine utilizes an external central frame which enhances engine cost, serviceability and efficiency. For example, a front plate structure of the external central frame is removably attached to a combustor section, a rear plate structure of the external central frame is removably attached to a compressor section and a plurality of elongate tie members extend between the front plate structure and the rear plate structure. Thus, the external central frame provides a cost savings by simplifying the structure design and eliminating the need for high stress and high temperature capability materials of a portion of the components of the gas turbine engine, reduces and may eliminates the need for thermal shields and insulation by separating the hot flow path from the engine components, and reduces the complexity of serviceability.
