Embodiment Construction

[0042] Reference will now be made in more detail to the provided embodiments, one or more examples of which are illustrated in the accompanying drawings. Each example is provided by way of explanation, not limitation of the disclosed embodiments. In fact, those skilled in the art will recognize that various modifications and changes can be made to the present embodiments without departing from the scope or spirit of the invention. For example, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Therefore, it is intended that the present invention cover such modifications and changes as the appended claims and their equivalents.

[0043] The present embodiment applies eg to gas turbine engines for aviation, power generation, industry or marine where the combustor burns fuel and discharges the hot combustion gases into a high pressure turbine. Exemplary structures and methods provide a combined oi...

Abstract

The present invention relates to a combined oil pan apparatus, the combined oil pan apparatus having a structure in which the oil pan is moved more closely together, the arrangement of the supply, return and discharge circuits and lines is simplified due to the commonality between them.

Description

technical field [0001] Embodiments herein relate generally to apparatus and methods for combining two separate oil sumps in a single area to save space and weight in a turbine engine. More specifically, but without limitation, embodiments herein relate to apparatus and methods for mounting two oil sumps to a single frame and sharing oil supply and discharge lines. Background technique [0002] In a turbine engine, air is pressurized in a compressor and mixed with fuel in a combustor to produce hot combustion gases, which flow downstream through the turbine stages. These turbine stages obtain energy from the combustion gases. A high pressure turbine includes a first stage nozzle and a rotor assembly including a disk and a plurality of turbine blades. The high-pressure turbine first receives hot combustion gases from the combustor and includes first-stage stator nozzles that direct the combustion gases downstream through a row of high-pressure turbine rotor blades that flow ...
